Agricultural costs for reducing nitrogen surpluses in the Weser river basin
Provedor de dados: 31
Autores: Heidecke,   Claudia; Kreins,   Peter.
Agriculture is to a large part responsible for nitrate leaching into groundwater and rivers in Germany, especially in highly intensive agricultural regions. To evaluate the link between nitrogen surpluses from agriculture and nutrient leaching into ground- and surface waters, a model network to analyse current and future nitrogen surplus developments and water quality is set up by connecting hydrological and hydrogeological models with the German agricultural sector model RAUMIS. A set of different environmental measures and their costs is selected to fulfil surface and groundwater targets of the European water framework directive (WFD) for the case of the Weser River basin. Results show that with additional agri-environmental measures covering around 1...

ASYMMETRIC PRICE TRANSMISSION IN THE ISRAELI CITRUS EXPORT SECTOR IN THE AFTERMATH OF LIBERALIZATION
Provedor de dados: 31
Autores: Goetz,   Linde; von Cramon-Taubadel,   Stephan.
The Israeli citrus export sector was liberalized in 1991 with the aim to increase citrus growers’ income and to improve overall efficiency of the international citrus marketing channel. However, the former government export monopoly’s activities were mainly taken over by four large companies accounting for over 90% of total Israeli citrus market exports. In addition, citrus exporters maintained the monopoly’s consignment system, substantially limiting transparency on how the grower price is determined. This lead the government to intervene in the newly liberalized market by implementing a minimum price agreement in the 1994/95 season to protect citrus growers against exporters’ abuse of market power. In this paper we analyze whether market power was...

Determinants of adoption and intensity of use of improved maize varieties in the Central Highlands of Ethiopia: A Tobit analysis
Provedor de dados: 31
Autores: Alene,   Arega D.; Poonyth,   Daneswar; Hassan,   Rashid M.
This study employed a Tobit model to examine factors that influence the adoption and intensity of utilisation of improved maize varieties in the West Shoa Zone in the central highlands of Ethiopia. The estimated results indicate that level of education, household labour, farm size, extension services, farm income, and timely availability of improved maize seeds significantly influence the adoption and intensity of use of improved maize. It also showed that the impact of off-farm income and age of the household head on adoption and intensity of use of improved maize seed was insignificant.

Irrigated Acreage Projections in Georgia
Provedor de dados: 31
Autores: Cai,   Ruohong; Mullen,   Jeffrey D.; Bergstrom,   John C.
Irrigated acreage is an important indicator for agricultural water demand which is a major category of water use. Three methodologies were applied in this study to project irrigated acreage of major crops in Georgia from 2010 to 2050. These three methodologies show consistent results. Total irrigated acreage of major crops in Georgia is projected to increase for the next 40 years. The acreage projection results provide useful information for Georgia agricultural policy makers and farmers.  However, the methodologies used in the study have some limitations. They can only be used under certain assumptions. Thus, better methodologies are needed for future related research.

Economic Determinants of Invasion and Discovery of Nonindigenous Insects
Provedor de dados: 31
Autores: Hlasny,   Vladimir; Livingston,   Michael J.
Introductions of nonindigenous organisms into the United States have been linked to international trade. The individual contributions of imports, immigration, and international travel, however, are poorly understood because introduction dates are unavailable. We examine relationships between economic trends and discoveries of nonindegenous insects and use these relationships to infer the timing and determinants of introductions. We find that a few variables can explain much variation in species introductions and identifications. The most significant contributor to the introduction appears to be agricultural imports. Currently available proxies for academic effort are weak determinants of the probability that introduced species are identified.

Estimating the Adoption of Bt Eggplant in India: Who Benefits from Public-Private Partnership?
Provedor de dados: 31
Autores: Krishna,   Vijesh V.; Qaim,   Matin.
The study analyzes ex-ante the adoption of insect resistant Bt eggplant in India. Farmers' willingness to pay (WTP) is estimated using the contingent valuation method. Given the economic importance of insect pests, the average WTP for proprietary Bt hybrids is more than four times the current price of conventional hybrids. Since the private innovating firm has shared its technology with the public sector, it is likely that public open-pollinated Bt varieties will also be released after a small delay. This will reduce farmers' WTP for Bt hybrids by 35%, thus decreasing the scope for corporate pricing policies. Nonetheless, ample profit potential remains. Analysis of factors influencing farmers' adoption decisions demonstrates that public Bt varieties will...

Autores: Kipkoech,   Anderson Kipruto; Schulthess,   Fritz; Yabann,   Wilson K.; Maritim,   Henry K.; Muchugu,   Erick; Mithofer,   Dagmar.
The braconid larval parasitoid Cotesia flavipes Cameron was introduced from Asia into East and Southern African region starting in 1993 to control the invasive exotic maize stemborer Chilo partellus (Swinhoe) (Lepidoptera: Crambidae). A quasi-experiment was constructed using farmers that applied sublethal dosages of pesticide in assessing the counterfactual for the impact of the establishment of the introduced parasitoid in five countries in the region. Logistic regression method was used to estimate the probability that farmers’ would inadvertently exclude parasitoids in their maize field. Thereafter the propensity score matching method was used to find corresponding farmers excluding parasitoids among those who did not for yield comparison. The...

TECHNOLOGICAL CHANGE, TECHNICAL AND ALLOCATIVE EFFICIENCY IN CHINESE AGRICULTURE: THE CASE OF RICE PRODUCTION IN JIANGSU
Provedor de dados: 31
Autores: Fan,   Shenggen.
This paper develops a frontier shadow cost function approach to estimate empirically the effects of technological change, technical and allocative efficiency improvement in Chinese agriculture during the reform period (1980-93). The results reveal that the first phase rural reforms (1979-84) which focused on the decentralization of the production system have had significant impact on technical efficiency but not allocative efficiency. During the second phase reforms which was supposed to focus on the liberalization of rural markets, technical efficiency improved very little and allocative efficiency has increased only slightly, however. In contrast, the rate of technological change continued to increase, although at a declining rate during the second phase...

Evaluating Marketing Channel Options for Small-Scale Fruit and Vegetable Producers: Case Study Evidence from Central New York
Provedor de dados: 31
Autores: LeRoux,   Matthew N.; Schmit,   Todd M.; Roth,   Monika; Streeter,   Deborah H.
An investigation of the relative costs and benefits of marketing channels used by typical small-scale diversified vegetable crop producers is conducted. Using case study evidence from four small farms in Central New York, this study compares the performance of wholesale and direct marketing channels, including how the factors of risk, owner and paid labor, price, lifestyle preferences, and sales volume interact to impact optimal market channel selection. Given the highly perishable nature of the crops grown, along with the risks and potential sales volume of particular channels, a combination of different marketing channels is needed to maximize overall firm performance. Accordingly, a ranking system is developed to summarize the major firm-specific...

Adoption of Maize Production Technologies in the Coastal Lowlands of Kenya
Provedor de dados: 31
Autores: Wekesa,   E.; Mwangi,   Wilfred; Verkuijl,   Hugo; Danda,   Milton Kengo; De Groote,   Hugo.
Maize is the major food crop grown in the coastal region of Kenya and constitutes a major component of the diet of the population in the region. However, average yields are far below the potential for the region and low production levels create serious food deficits. Over the years, new technologies have been introduced but adoption has remained low, especially for fertilizer. This paper examined current maize-farming practices and technological and socioeconomic factors that influenced adoption in the Kilifi and Kwale Districts of the Coast Province, that together account for half of maize production in the region. The study found low adoption levels for improved maize varieties and technology, especially fertilizer, among farmers in the area. Farmers...

Relationships between Agricultural policies and Environmental Effects in Japan: An Environmental-Economic Integrated Model Approach
Provedor de dados: 31
Autores: Sasaki,   Hiroki.
This study investigates the optimal agricultural land use allocation and nitrogen application to a representative Japanese farm. The site-specific nature of numerous agri-environmental issues necessitates analysis at a disaggregated level in order to capture the underlying heterogeneity of agricultural productivity and environmental sensitivity across different parcels of land. This study adopts an integrated approach—a decision-making economic model for representative farms is combined with a stylized site-specific biophysical model, which quantifies the impact of different policy instruments on agricultural production practices and on multiple environmental effects. This model estimates the government budget outlays and social welfare, which require...

Decaffeinated? Situation, Trends, and Prospects for Smallholder Coffee Production in Rwanda
Provedor de dados: 31
Autores: Loveridge,   Scott; Nyarwaya,   Jean Baptiste; Shingiro,   Emmanuel.
Most Rwandan coffee is currently grown and processed the same way it was a decade ago.  Consequently, Rwanda’s coffee production and marketing system has not been able to keep up with  changes in the global market for high quality coffee. Given world market gluts of relatively poor quality coffee, Rwanda is now exporting a product that fetches low prices. Despite the challenges in coffee marketing and production, coffee remains one of Rwanda’s most important official sources of foreign exchange and the drop in production is of major concern to both the public and private sectors. In an effort to assist decision makers in the coffee sector better understand factors affecting farmers’ production decisions and their attitudes about coffee, the FSRP fielded a...

The Adoption and Impact of Improved Maize and Land Management Technologies in Uganda
Provedor de dados: 31
Autores: Sserunkuuma,   Dick.
In spite of the fact that the Ugandan National Agricultural Research System has developed and released several production-enhancing technologies over a century, yields of most major crops at the farm level have been low. Given that about 80 percent of Uganda’s labor force is employed in agriculture, the scope for sustainable poverty reduction in Uganda depends very much on improving agricultural productivity. It is in this context, this paper examines why there has been poor adoption of production-enhancing technologies in the production of maize, which is a major crop in Uganda and what the impacts of the exiting production environment are on factor payments. This study reveals that farmers do not pay proper attention to soil fertility management, which...

Distribution of Benefits and Adoption of Bt Cotton in Pakistan: Ex-ante Analysis
Provedor de dados: 31
Autores: Nazli,   Hina; Sarker,   Rakhal; Meilke,   Karl D.; Orden,   David.
This poster presents the potential impact of Bt cotton adoption in Pakistan. The size and distribution of economic benefits from the commercial adoption of Bt cotton in Pakistan are examined under four hypothetical scenarios. The adjusted economic surplus model is used to measure total benefits and their distribution between producers, consumers and technology innovators. To account for uncertainty in key parameters, the stochastic simulation techniques is applied. The results show that the total net benefits of adopting Bt cotton in Pakistan are large. As a result of increase in production, farmers get considerable benefits despite a decline in price. The share of benefits to innovators is small. The results indicate that the total cost of adopting latest...

Antidumping and Market Power in the Agriculture Sector, with a Special Case Study of the Fresh Tomato Industry
Provedor de dados: 31
Autores: Baylis,   Katherine R.
In this article we highlight the anticompetitive nature of antidumping (AD) legislation. Antidumping legislation was set up to protect domestic firms from predatory pricing by foreign firms. We argue that protecting highly concentrated industries drastically reduces competition at home. In cases where the industry consists only of one or two firms, import restriction may breed monopolies at the expense of domestic consumers. This article looks at cases filed by the agriculture sector, and at the market concentration of industries in this sector, to illustrate the above possibility. We study the case of fresh tomatoes in detail to further demonstrate the anticompetitive nature of AD legislation. We show the effect of AD legislation on imports, as well as...

Incentive to reduce crop trait durability
Provedor de dados: 31
Autores: Ambec,   Stefan; Langinier,   Corinne; Lemarie,   Stephane.
Inbred line seed producers face competition from their own consumers: farmers who save part of their harvest can costly self-produce. To reduce this competition, seed producers can switch to non-durable hybrid seed production.  In a two-period model, we investigate what is the impact of crop durability on self-production, pricing strategies and switching decision. We first study the pricing decisions and switching decisions of an inbred line seed monopoly. Then, we analyze how the monopoly's behavior is affected by the entry of a hybrid seed producer. We also examine how the introduction of royalties on farmers who self-produce improves efficiency.  Our main finding is that, for some constellation of costs, an inbred line seed monopoly has an incentive to...

Modelling Forestry in Dynamic General Equilibrium
Provedor de dados: 31
Autores: Lennox,   James A.; Turner,   James A.; Daigneault,   Adam J.; Jhunjhnuwala,   K.
Adequately representing dynamic characteristics of land use change and forestry in computable general equilibrium models is challenging but essential if modellers are to provide credible assessments of policies that directly or indirectly influence these phenomena. In this paper, we show how a dynamic representation of planted or naturally regenerating forests may be integrated within a neoclassical, intertemporal general equilibrium model. We demonstrate the application of such a model to assess the impacts of including forestry within a hypothetical emissions trading scheme in the US, showing the resulting changes in land use and increases in the optimal rotation length.

IMPACTS OF POLICY REFORM ON SUSTAINABILITY OF HILL FARMING IN UK BY MEANS OF BIO-ECONOMIC MODELLING
Provedor de dados: 31
Autores: Acs,   Szvetlana; Hanley,   Nick; Dallimer,   Martin; Robertson,   Philip; Gaston,   Kevin J.; Armsworth,   Paul R.
Hill farming in UK is experiencing very difficult economic circumstances and many farmers rely on subsidies provided by the government for a large fraction of their income. The Peak District National Park is used as a case study to examine how farmers might respond to current policy changes � in particular, the move from area- and headage-based payments to the Single Farm Payment, and how optimal business plans should respond to these changes. The objective of this paper is thus to develop production models that predict how farmers will respond to changing policy framework conditions. For this purpose socio-economic surveys were carried out on 44 sample farms, in order to investigate how the land is managed on hill farms including ongoing policies and...

Greenhouse Tomatoes Change the Dynamics of the North American Fresh Tomato Industry
Provedor de dados: 31
Autores: Cook,   Roberta L.; Calvin,   Linda.
The rapid growth of the North American greenhouse tomato industry has changed the longstanding dynamics of the fresh tomato industry. During the 1990s, Canada emerged as the largest North American producer of greenhouse tomatoes, a prominence it never attained in the fresh field tomato industry. The United States and Mexico have also become important greenhouse tomato producers, consistent with their long dominance in North American fresh field tomato production. Greenhouse tomatoes have changed the look of U.S. retail tomato sales, where they now account for 37 percent of the quantity sold of fresh tomatoes. While the primary U.S. fresh field tomato product, the mature green tomato, long dominated retail sales, its share has decreased significantly due to...

Plant Breeding: A Long-term Strategy for the Control of Zinc Deficiency in Vulnerable Populations
Provedor de dados: 31
Autores: Ruel,   Marie T.; Bouis,   Howarth E.
Because trace minerals are important not only for human nutrition, but for plant nutrition as well, plant breeding holds great promise for making a significant low-cost and sustainable contribution to reducing micronutrient deficiencies in humans, and may have important spinoff effects for increasing farm productivity in developing countries in an environmentally beneficial way. This paper describes ongoing plant breeding research that could increase the intake of bioavailable zinc from food staple crops among vulnerable populations in developing countries. The three most promising plant breeding strategies to achieve this goal are (1) increasing the concentration of zinc in the plant, (2) reducing the amount of phytic acid (a strong inhibitor of zinc...

THE PRICE COMPETITIVENESS OF HUNGARIAN WINES IN EUROPEAN UNION MARKETS
Provedor de dados: 31
Autores: Bozsik,   Norbert.
In the case of homogeneous goods (corn, eggs, milk, etc.) the price differential between products is the strongest determinant of success in market competition. In these days, however, it is more and more the highly processed foodstuffs that land on the consumer’s table. Wine is one of these. This study appraises the price competitiveness of Hungarian wines on EU markets. The question is to what extent do price differences determine the competitiveness of wine on potential markets? Or does a lower price give a real advantage to a special product like wine? Or is the demand for a product due to factors other than price? Our findings show that most Hungarian wines, except bottled white quality wines, are compatible on EU markets as far as prices are...

Autores: Islam,   Q.; Mullen,   John D.; Brennan,   John P.; Li,   G.D.; Helyar,   K.R.; Jones,   Randall E.
Acid and acidifying soils occur extensively in Australia. Currently, some 90 million hectares of agricultural land in Australia is considered to be acidic and around 35 million hectares are considered to be highly acidic which is both a serious agricultural and environmental problem. The nature, impact, and causes of soil acidification vary across Australia, as do farming systems and the institutional and socioeconomic issues relating to land management. In high-rainfall areas of south-eastern Australia, managing acid soils is particularly difficult in permanent pasture systems. In this paper, an economic analysis is made of the results of a long-term trial (MASTER – Managing Acid Soils Through Efficient Rotations) aimed at developing a sustainable...

Autores: Greene,   Catherine R.; Slattery,   Edward; McBride,   William D.
Organic agriculture has established a foothold in many U.S. farm sectors, particularly among horticultural specialties, but the overall use of organic practices lags behind that of many other countries. Recent data from several producer surveys illustrate notable differences and similarities between organic and conventional farmers. Emerging issues in the organic sector include dampened consumer demand resulting from the weaker U.S. economy and potential competition from new labels like the “locally grown” label.

COMPLIANCE WITH EUREPGAP STANDARDS: DETERMINANTS, COSTS AND IMPLICATIONS ON PROFITABILITY AMONG SMALLHOLDER FRENCH BEANS EXPORTERS IN KIRINYAGA DISTRICT, KENYA
Provedor de dados: 31
Autores: Muriithi,   Beatrice Wambui.
Horticulture provides many developing countries with opportunities for export diversification, poverty alleviation and rural development. However, stringent public and private-sector food-safety standards, for example EurepGap, pose a challenge especially to small export farmers. Compliance with these standards entails costly investments that may be a burden to smallholder farmers, failure to which might lead to their exclusion in the global market. A number of questions which require empirical research arise to confirm or refute these concerns. The study assesses awareness of the EurepGap standards among smallholder farmers and analyzes the critical factors influencing their compliance. It also identifies the costs of complying with these standards and...

Has growth in productivity in Australian broadacre agriculture slowed?
Provedor de dados: 31
Autores: Sheng,   Yu; Mullen,   John D.; Zhao,   Shiji.
Agricultural productivity growth has been strong relative to other sectors in the Australian economy, and relative to the agricultural sectors of other developed countries. However, as commonly observed among other developed economies, growth in productivity in the broadacre sector of Australian agriculture seems to have slowed in the past decade. This paper uses the adjusted cumulative sum square (CUSQ) index to examine the trend stability of total factor productivity in Australian broadacre agriculture over the period 1952-53 to 2006-07. The results show that a significant slowdown occurred around the mid-1990s. Further analysis shows that the slowdown in productivity growth is driven by a longterm decline in public R&amp;D investment in addition to poor...

Performance of traditional cooperatives: the Portuguese Douro wine cooperatives
Provedor de dados: 31
Autores: Rebelo,   Joao; Caldas,   Jose Vaz; Matulich,   Scott C.
Globalization is challenging the very core of cooperative governance and ownership decision, especially in Southern European countries, like Portugal, where a large number of producers are organized in traditional and Mediterranean-style agricultural cooperatives. This paper analyses the effects of governance and control variables related with size over two alternative indicators of performance: revenues transferred to members/patrons and capital structure. The results suggest that these cooperatives have difficulties being sustainable in the more competitive global wine markets, if they follow, essentially, a practice of maximum patronage refund, reducing their capacity to improve leverage and to finance more profitable, but risky, long run investments.

Economic evaluation of a weed-activated sprayer for herbicide application to patchy weed populations
Provedor de dados: 31
Autores: Bennett,   Anne L.; Pannell,   David J.
Spatial distribution of weeds in a crop is patchy. Traditional boom sprayers waste herbicide by applying it to areas where weed density is already low. A new technology, Weed Activated Spray Process (WASP), uses sensors to detect the presence of weeds and control spray nozzles accordingly. The economic benefits of this technology to extensive crop farmers in Western Australia are investigated using a model based on the economics of information. Existing technology is likely to reduce profits because the weed density at which it switches off spraying is too high. Even if sensitivity to low densities could be improved, likely benefits of pre‐crop usage would still be very low or negative.

EXOGENOUS PRODUCTION SHOCKS AND TECHNICAL EFFICIENCY AMONG TRADITIONAL IVORIEN RICE FARMERS
Provedor de dados: 31
Autores: Sherlund,   Shane M.; Barrett,   Christopher B.
This paper uses a unique panel data set and data envelopment analysis (DEA) to obtain estimates of technical efficiency for 492 traditional rice plots in Côte d'Ivoire.  The objective of this paper is to explore the importance of explicitly controlling for exogenous shocks to production in technical efficiency estimation.  We show how omission of such variables in highly stochastic production environments can lead to serious inferential errors, with potentially significant policy implications.  Conventional DEA estimation of a production frontier, followed by second-stage Tobit estimation of the correlates of plot- level technical efficiency, suggest widespread and substantial inefficiency related to crop fragmentation and seed varieties.  However, when...

Autores: Miller,   Stephen E.; Kahl,   Kandice H.; Rathwell,   P. James.
We estimate actuarially sound premium rates for individual yield guarantee and income protection crop insurance products for Georgia and South Carolina peaches.  In most cases, the premium rate for an income protection product equals or exceeds the premium rate for an individual yield guarantee product for a given coverage level and average farm yield.  Although the premium rates for the two products differ in a statistical sense, they do not appear to differ in an economic sense except at high coverage levels for growers with very high yields.

The aim of the study is to review the vertical and horizontal reshuffling that took place in a specific area of the Hungarian grain product cycle, i.e. raw material production, and its effect on the demand-side power structure. The answers derived from questionnaires and in-depth interviews allowed the classification of buyers using cluster analysis, and also the modeling of their decisions during the price negotiation. The completed analysis shows us that on the grain market, price leaders are primarily among the large trading companies and holdings, which can be attributed to their size, storage capacity, logistical capabilities and strategy. Processing (mills, feed mixers, seed-sellers), integrator, retail and other companies on the grain market are...

Autores: Debnath,   Deepayan; Stoecker,   Arthur L.; Epplin,   Francis M.
Biorefineries that plan to use switchgrass exclusively will have to account for year-to-year variability in feedstock production. The objective of this research is to determine the quantity, class, and location of land to lease for switchgrass production to provide for the needs of a biorefinery. The firm could elect to lease land based on average switchgrass yields or to lease to attempt to insure that even in the worst case (based on historical data) production year the area leased will produce sufficient feedstock to fully provide for the needs of the biorefinery. EPIC was used to generate empirical distributions of switchgrass biomass yields for three land classes for each of 30 counties. Mathematical programming was used to address the objectives and...

Autores: Minot,   Nicholas.
Given that Sub-Saharan Africa has the highest incidence of poverty and malnutrition in the world, the stagnation in per capita grain production there is worrisome. Since 1970, per capita grain production in Sub-Saharan Africa has declined more than 10 percent. Increasing the productivity of staple foodcrops will help poor farmers and consumers, and one of the most sustainable ways to expand food production in Sub-Saharan Africa is to generate new technologies—including staple seed varieties—that are adapted to the constraints of the continent's small-scale farmers. The region thus requires a cost-effective system of seed production and distribution to ensure that appropriate seeds are delivered to farmers. Both the private and public sectors have a role to...

POTENTIAL CORN ACREAGE EXPANSION FOR ETHANOL PRODUCTION: WESTERN NORTH DAKOTA
Provedor de dados: 31
Autores: Gustafson,   Cole R.
Several recent developments have stimulated farmers' interest in raising corn for ethanol production in northwestern North Dakota.  The purpose of this study is to estimate the corn supply response of western North Dakota farmers for ethanol production.  Two focus groups of western North Dakota farmers (Williston and Minot) were organized.  The market premium over prevailing local corn prices that was required by western North Dakota farms to entice additional production of an ethanol specific hybrid was determined.  Aggregation of these farm responses yielded a supply function of corn for the region.  Results show that sufficient corn can be produced in the surrounding region to support a 12 million gallon ethanol facility if modest price premiums are...

The net impact of pest-resistant GM crops on the welfare of both producers and consumers in developing countries is currently unknown and subject to speculation. This study uses choice-based conjoint protocol to estimate the net impact of pest-resistant Genetically Modified (GM) cowpea on net social welfare in Benin given price and income risks. Results imply that Bt cowpea will increase expected net social welfare by about $US 50 million per year in Benin given no inefficiencies in the seed sector. If inefficiencies in the seed sector are such that cowpea growers can access Bt cowpea seeds only 50% of the time, net benefits from Bt cowpea drop to about $US 11 million per year.

INTERNATIONAL AND INSTITUTIONAL R&amp;D SPILLOVERS: ATTRIBUTION OF BENEFITS AMONG SOURCES FOR BRAZIL'S NEW CROP VARIETIES
Provedor de dados: 31
Autores: Pardey,   Philip G.; Alston,   Julian M.; Chan-Kang,   Connie; Magalhaes,   Eduardo Castelo; Vosti,   Stephen A.
In general, reported rates of return to agricultural R&amp;D are high, but questions have been raised about upward biases in the evidence.  Among the reasons for this bias, insufficient attention to attribution aspects-matching of research benefits and costs-is a pervasive problem, the magnitude of which is illustrated here with new evidence for Brazil.  Over the period 1981 to 2003, varietal improvements in upland rice, edible beans, and soybeans yielded benefits attributable to research of $14.8 billion in present value (1999 prices) terms; 6.1 percent of the corresponding value of crop output.  If all of those benefits were attributed to Embrapa, a public research corporation accounting for more than half Brazil's agricultural R&amp;D spending, the...

The farm level economic impacts of the Farm Security and Rural Investment Act of 2002 on representative crop and livestock operations are projected in this report. The analysis was conducted over the 2001-2007 planning horizon using FLIPSIM, AFPC’s whole farm simulation model. Data to simulate farming operations in the nation’s major production regions came from two sources: - Producer panel cooperation to develop economic information to describe and simulate representative crop, livestock, and dairy farms. - Projected prices, policy variables, and input inflation rates from the Food and Agricultural Policy Research Institute (FAPRI) January 2003 Baseline. The FLIPSIM policy simulation model incorporates the historical risk faced by farmers for prices and...

THE PERFORMANCE OF AGRICULTURAL MARKET ADVISORY SERVICES IN CORN AND SOYBEANS
Provedor de dados: 31
Autores: Irwin,   Scott H.; Martines-Filho,   Joao Gomes; Good,   Darrel L.
The purpose of this paper is to evaluate the performance of market advisory services for the 1995-2000 corn and soybean crops. A new database from the Agricultural Market Advisory Services (AgMAS) Project is used in the evaluation. This database should not be subject to survivorship and hindsight biases. Overall, the results provide limited evidence that advisory programs as a group outperform market benchmarks, particularly after considering risk. In contrast, some evidence exists that advisory programs as a group outperform the farmer benchmark, even after taking risk into account. There is little evidence that advisory programs with superior performance can be usefully selected based on past performance.

Modeling economic, biophysical, and environmental dynamics of potato production system
Provedor de dados: 31
Autores: Khakbazan,   Mohammad; Hamilton,   Cliff; Belcher,   Kenneth W.
The adoption and use of diversified cropping practices has become widely accepted by producers. However, the profitability of an enterprise is dependent on the biophysical and economic factors. The biophysical factors determine the enterprise relationship among the various crops, their interactions with the ecosystem, and how each of them fits into the overall management plan. The economic factors determine the relative advantage of each crop and service in the farm plan. Although there have been experimental studies in Canada examining the impacts of rotations on the agronomics of field crops, there is limited research in modeling economic and environmental dynamics of the potato production system. Potato production in Manitoba has rapidly increased in...

Benefit cost analysis is a tried and tested analytical framework that can clearly  communicate likely net changes in social welfare from investment decisions to  diverse stakeholder audiences. However, in a plant biosecurity context, it is often  difficult to predict policy benefits over time due to complex biophysical interaction between invasive species and their hosts. In this paper, we demonstrate how benefit cost analysis remains highly relevant to biosecurity decision-makers using the example of a plant pathogen targeted for eradication from banana growing regions of  Australia, banana bunchy top virus. We develop a partial budgeting approach using a stratified diffusion spread model to simulate the likely benefits of eradication to the banana...

SOIL QUALITY ATTRIBUTE TIME PATHS:  OPTIMAL LEVELS AND VALUES
Provedor de dados: 31
Autores: Smith,   Elwin G.; Lerohl,   Mel L.; Messele,   Teklay; Janzen,   H. Henry.
We develop a dynamic soil quality model to evaluate optimal cropping systems in the northern Great Plains. Modeling soil quality attributes is feasible, and attribute model results apply to a wide range of soils. A crop production system with continuous spring wheat and direct planting is the most profitable system. This system has low soil erosion and high quality attributes, indicating the benefits of increased soil quality exceed the higher maintenance costs. On-site value of additional soil organic carbon (OC) ranges from $1 to $4/ton OC/hectare/year. These values for soil OC impact the optimum tillage practice, but not the crop rotation.

Muddied Waters: Estimating the national economic cost of soil erosion and sedimentation in New Zealand
Provedor de dados: 31
Autores: Eastwood,   Callum; Krausse,   Michael; Alexander,   Robert R.
Soil erosion research in New Zealand has focused on the on-site costs of soil loss in the form of production loss and storm damage. Subsidization and implementation of soil conservation measures have primarily been justified through maintenance or improvement of farm productivity levels. The shift in responsibility for soil conservation management and damage remedies from national to regional government has highlighted public good issues raised by soil erosion. This paper develops an inventory and assessment of the relative magnitude of the impacts of soil erosion and sedimentation in New Zealand. It also provides an estimate of the total economic costs of these impacts based on the limited data available. The impacts of greatest economic significance are...

Estimating productivity of water at different spatial scales using simulation modeling
Provedor de dados: 31
Autores: Droogers,   Peter; Kite,   Geoff.
A clear understanding of the current water balance is required to explore options for water saving measures. However, measurement of all the terms in the water balance is infeasible in terms of spatial and temporal scale, but hydrological simulation models can fill the gap between measured and required data. For a basin in Western Turkey, simulation modeling at three different scales, field, irrigation scheme and basin scale, was performed to obtain all terms of the water balance. These water balance numbers were used to calculate the Productivity of Water at the three spatial levels distinguished to assess the performance of the systems.

Local Markets, Local Varieties: Rising Food Prices and Small Farmers' Access to Seed

Autores: Smale,   Melinda; Cohen,   Marc J.; Nagarajan,   Latha.
In-depth field research—undertaken by IFPRI with the Food and Agriculture Organization of the United Nations (FAO) and other partners in India, Kenya, and Mali—brings to light new evidence about farmers’ access to seed and the role of village markets in supplying it, with a focus on semi-arid environments.1 The findings point to several policy options aimed at improving the effectiveness of these markets, which can be crucial for reducing the potential negative impacts of high food prices. Such options might be considered in tandem with those recommended for more favorable environments, where seed systems already function more effectively. This brief introduces the issues that drove this research project, relevant concepts, and methods. The accompanying...

Charging for the use of plant varieties
Provedor de dados: 31
Autores: Kingwell,   Ross S.
Private and many publicly funded plant breeding organisations charge farmers for use of varieties they develop. This article compares four alternative charging mechanisms and outlines responses to these alternatives by farmers and plant breeders. Risk‐averse farmers and breeders are shown to have opposite preferences for charging mechanisms. Results suggest profit‐based or royalties are preferred by farmers whereas breeders prefer area or tonnage‐based royalties. Risk‐sharing arrangements between both parties could lead to an overall preference for profit‐based or royalties. However, this finding is subject to important caveats and practical limitations.

2001 OUTLOOK OF THE U.S. AND WORLD SUGAR MARKETS
Provedor de dados: 31
Autores: Koo,   Won W.; Taylor,   Richard D.
This report evaluates the U.S. and world sugar markets for 2000-2010 by using the Global Sugar Policy Simulation Model. This analysis is based on assumptions about general economic conditions, agricultural policies, population growth, weather conditions, and technological changes.  Both the U.S. and world sugar economies are predicted to improve over the next ten years after the current over supply is reduced. World demand for sugar is expected to grow faster than world supply, resulting in gradually increasing Caribbean sugar prices from 8.51 cents/lb in 2000 to 12.67 cents/lb in 2010. The U.S. wholesale price of sugar is projected to increase from 22.5 cents/lb in 2000 to 26.6 cents/lb in 2010, if the United States maintains its sugar programs. World...

Effects of Soybean Checkoff Research Expenditures on U.S. Soybean Yields and Net Revenue: A Time Series Analysis
Provedor de dados: 31
Autores: Bessler,   David A.
Statistical methods are used to study relationships between research expenditures (adjusted for inflation) made from producer checkoff programs and soybean yields and net revenues in the United States for the years 1978 – 2007. Results presented are for yield and net revenue data and research expenditures for the entire United States. We find that research expenditures over the years 1994 to 2007 are responsible for a 0.95 bushel per acre per year increase in soybean yields. We calculate net producer revenues to be about $17 per acre higher than would have been the case without the soybean research checkoff expenditures.

Autores: Mohanty,   Samarendu; Smith,   Darnell B.; Peterson,   E. Wesley F.
In this paper, relationships between U.S. and Canadian wheat prices are examined using cointegration and error correction approach.  The use of an error correction model is appropriate because U.S. and Canadian wheat prices are first differenced stationary and cointegrated.  The results suggest that both U.S. durum and hard spring wheat prices respond to restore the equilibrium relationship with the corresponding Canadian price while the Canadian price does not respond to restore equilibria.  That is, the structure of the respective policies is such that Canadian markets are largely insulated from influences flowing from the United States while U.S. markets are not insulated from Canadian influences.  These results could be interpreted to support the...

THE CHANGING FACE OF THE U.S. GRAIN SYSTEM: DIFFERENTIATION AND IDENTITY PRESERVATION TRENDS
Provedor de dados: 31
Autores: Elbehri,   Aziz.
This report examines current trends in the U.S. grain industry. Many identity preservation(IP) grain systems have emerged recently, driven by a confluence of supply and demand factors. IP grain requirements for specific production protocols, marketing channels, and quality assurance depend on whether the crops are trait-specific, non-GM (genetically modified), organic, or pharmaceutical. Cost structures vary according to the relative importance of segregation and risk management. High information management, greater market coordination, and frequent reliance on contracts characterize IP grains. IP grain markets are also inherently riskier, with volatile supply, inelastic demand, and fluctuating price premiums. Increasing grain differentiation is altering...

An Economic Risk Analysis of Tillage and Cropping Systems on the Arkansas Grand Prairie
Provedor de dados: 31
Autores: Hignight,   Jeffrey A.; Watkins,   K. Bradley; Anders,   Merle M.
No-till (NT) has been shown to reduce fuel, labor, and machinery costs compared to conventional-till (CT) but very few rice producers in Arkansas practice NT.  The low adoption rate is most likely due to difficulties in management but also limited information on the profitability and risk of NT.  Most rice producers are knowledgeable on NT costs savings but consider it less profitable due to yield reductions offsetting costs savings.  This study evaluates production costs, crop yields, and economic risk of both NT and CT in five rice-based cropping systems (continuous rice, rice-soybean, rice-corn, rice-wheat, and rice-wheat-soybean-wheat).  Yields, crop prices, and key input prices are simulated to create net return distributions.  Stochastic efficiency...

Access Issues for Plant Breeders in an Increasingly Privatized World

There is a growing trend to widespread privatisation of crop breeding, and there are grounds for expecting this trend to continue and even to accelerate. Possible consequences for Australian grain growers and the national interest of much greater private sector involvement in plant breeding are explored. Growing privatisation and commercialisation of plant breeding will lead to increased competition between plant breeders. While this increased competition has been at least partly driven by the potential for value creation, it also is likely to enhance value creation from plant breeding so long as there is adequate continuing investment in the capacity for plant breeding, and more particularly in productivity enhancing enabling technology. In the event of...

Irrigation vegetable farmers in Seymour District, Eastern Cape, have had problems concerning market access. Initial action by the researcher showed that problems can be solved. A survey showed younger farmers to be better educated, more businesslike and more eager to solve problems than older farmers. The unavailability of transport, poor infrastructure, lack of market information and to a lesser extent, dishonesty of some traders are major problems for these farmers. The community involved should be regarded as progressive, and can be expected to prosper once their problems have been solved.

Smallholder Heterogeneity and Maize Market Participation in Southern and Eastern Africa: Implications for Investment Strategies to Increase Marketed Food Staple Supply
Provedor de dados: 31
Autores: Mather,   David; Boughton,   Duncan; Jayne,   Thomas S.
In many African countries, as well as in other parts of the world where a significant part of the rural population is poor and food insecure, policymakers face what is called the food price dilemma. On the one hand, they need to provide farmers with incentives to increase the quantity of marketed food staples to feed a growing population, especially in rapidly growing urban centers where unrest can be politically destabilizing. On the other hand, because staple foods account for a large portion of total household expenditures for both urban and rural households, policymakers also are drawn to policies that lower the retail price of staple foods for consumers. Achieving both objectives – increasing marketed supplies of food staples while maintaining low...

Multiple Criteria Decision Making: Method Selection And Application To Three Contrasting Agricultural Case Studies
Provedor de dados: 31
Autores: Dooley,   A.E.; Sheath,   Gavin W.; Smeaton,   D.
Agribusiness, farm business and agricultural-environmental decisions which varied in their characteristics were used to evaluate multiple criteria decision making (MCDM) in an agricultural context. This paper discusses differences between the case studies, strengths and weaknesses of the methods used, and the success of the MCDM process based on participants’ expectations and experiences. While MCDM can help identify the best decision, the main benefits identified in using MCDM included better understanding of their own and other’s perspectives, a means to explain the decision and a structured way to work through the decision process. Key problem areas identified included time limitations, understanding and ownership.

THE ECONOMIC IMPACT OF THE RED IMPORT FIRE ANT ON THE HOMESCAPE, LANDSCAPE, AND THE URBANSCAPE OF SELECTED METROPLEXES OF TEXAS
Provedor de dados: 31
Autores: Lard,   Curtis F.; Hall,   Charles R.; Salin,   Victoria.
The imported fire ant has become a major economic pest to various sectors of the Texas economy.  In order to determine the economic impact of this pest on selected urban areas, an economic study was conducted in 1998-1999 in the 5 metroplexes of Austin, Dallas, Fort Worth, San Antonio and Houston to estimate the costs of controlling and managing fire ants.  The main purpose of this study was to estimate the annual economic impact of the fire ant on the households, schools, cities, and golf courses for the aforementioned metroplexes.  Other sectors within the urban areas are affected but this study shows the major impacted sectors that interfere with the human activities in living areas, work areas and recreational areas.

Autores: Feng,   Hongli; Rubin,   Ofir D.; Babcock,   Bruce A.
As the United States begins to move towards putting an economic value on reducing greenhouse gas (GHG) emissions, the need for improved accounting standards becomes acute. Lifecycle analysis (LCA), which involves the systematic collection and interpretation of material flow in all relevant processes of a product, has become the accepted procedure to use to determine greenhouse gas emissions of products ranging from transportation fuels, to building materials, to food production (Farrell et al., 2006; Hill et al., 2006; Owen, 2004). The basic motivation of LCA is that, to conduct a fair assessment of the environmental impacts of a product, it is necessary to take into account all of the processes throughout the product’s lifespan, including the extraction...

This report evaluates the U.S. corn sector, especially changes in ethanol production.  This analysis is based on a series of assumptions about general economic conditions, agricultural polices, weather conditions, and technological change.  Changes in ethanol production will impact the production, feed use, and exports of corn, as well as the general price level.  Federally mandated ethanol usage dictates the growth of ethanol production in the United States.  Other factors have limited impact on corn price.

Economic Implications of the Methyl Bromide Phaseout
Provedor de dados: 31
Autores: Osteen,   Craig D.
The pesticide methyl bromide is being phased out internationally under the Montreal Protocol. Methyl bromide has been used for over 50 years to control insect, nematodes, pathogens, and weeds. It is used for soil fumigation before planting many fruits, vegetables, ornamentals, and agricultural nurseries; for post-harvest fumigation of commodities in storage and prior to shipment; and for government-required quarantine treatment to prevent the spread of regulated exotic pests. Many U.S. users are concerned that existing alternatives to methyl bromide will be less effective and cause financial losses. To help mitigate the impacts of the phaseout, USDA, the U.S. Environmental Protection Agency (EPA), universities, and private firms are working to develop new...

Whole Truth in Herbicide Labelling
Provedor de dados: 31
Autores: Nordblom,   Thomas L.; Medd,   Richard W.
The 1999 National Competition Policy Review of Ag &amp; Vet Chemical legislation recommended, inter alia, that registrants no longer be required to prove ‘APPROPRIATE’ levels of efficacy of their products but only that the claims on product labels be ‘TRUE’. ‘Appropriate’ efficacy standards amount to market regulation, limiting economic competition from formulations with lower efficacies. Cheaper formulations with lower efficacies are excluded from the marketplace by such standards. Unanswered is the question of what ‘TRUTH’ on a label means in practical terms. Flexibility in dose rates and guidance with usage information is not always well-stated on herbicide labels. There is considerable evidence that efficacy of herbicide varies with dose and with...

The Agricultural and Food Policy Center (AFPC) at Texas A&amp;M University develops and maintains data to simulate eighteen representative cotton operations in major production areas of seven states. The chief purpose of this analysis is to project those farms’ economic viability for 2005 through 2009. The data necessary to simulate the economic activity of these operations is developed through ongoing cooperation with panels of agricultural producers in each of these states. The Food and Agricultural Policy Research Institute (FAPRI) provided projected prices, policy variables, and input inflation rates in their August 2005 Baseline. Under the August 2005 Baseline, only the moderately sized Tennessee cotton farm (TNC1900) and Louisiana cotton farm...

Some comments are required to put in perspective the results obtained by Ngwenya, Battese and Fleming (1997). In particular, it is necessary to examine their main conclusion that in 1988/89 there was a significant inverse relationship between the technical inefficiency of wheat farmers in the Eastern Free State and farm size, because this is in direct contrast with the findings of Van Zyl, Binswanger and Thirtle (1995) who used the same dataset.

The history of starvation in the world is very tightly linked with the history of humanity.  The problem of starvation was discussed in 1945 at the Worldwide Constitutional Conference of Food and Agriculture Organization of the United Nations.  The main goal of the organization was and remains a food policy for the benefit of all, in order to liberate all people from starvation.   Since 1950, there has been a notable decrease in agricultural production per capita in the developing counties in comparison to the needs.  In 1972 and 1973, poor harvests created a dramatic situation in many regions of the world and once again it was in the developing countries where people suffered the most.  In the Sahel countries, many thousand of lives would have been lost...

Autores: Henneberry,   Shida Rastegari; Schatzer,   Raymond Joe; El Beheisi,   Yousif.
The impact of hypothetical changes in yields, costs, and demand that might result from the organization of Oklahoma vegetable growers into cooperatives or other multifarmer marketing associations is estimated using a sector programming model. A comparative static analysis is used to evaluate the impact of these changes on planted acreage, growers' revenues, and consumers' and producers' surplus. The results of this analysis indicate that changes in demand are most effective in increasing revenues for Oklahoma growers.

Diffusion of Bt Cotton in India: Impact of Seed Prices and Technological Development
Provedor de dados: 31
Autores: Arora,   Anchal; Bansal,   Sangeeta.
Recent studies in the literature examining impact of government seed price intervention on adoption of Bt cotton get different results depending on the specifics of the situation analyzed. According to one study, reduction in seed prices enables farmers to buy seeds at lower prices and this can result in surge of area sown under Bt cotton. The other view holds that seed price interventions have little impact on the adoption rates rather these interventions may adversely affect firms’ incentives to innovate. Which of the two views characterize adoption of Bt cotton in India? Using three variations of dynamic logistic model, this paper analyzes the impact of certain economic factors like seed prices, technological development, and cotton prices on the...

The size of the Texas-Oklahoma spot market analyzed by the Daily Price Estimation System (DPES) for the 2000/2001 marketing year decreased considerably from the previous year. The average price received by producers during the 2000/2001 marketing year was about 50.9 cents/lb. The 2000 crop was generally of good quality, but the averages for the first digit of the color grade and leaf grade detoriated as compared with the 1999 crop. The percentage of bales having level 1 and 2 bark, and level 1 and 2 other extraneous matter decreased in comparison to the 1999 crop. With the exception of the second digit of the color grade price discounts for the 2000 crop decreased for all quality attributes. The premiums for the first digit of the color grade and strength...

Analysis of Production Efficiency of Mexican Coffee-Producing Districts
Provedor de dados: 31
Autores: Cardenas,   Gabriela; Vedenov,   Dmitry V.; Houston,   Jack E.
Despite the decline of coffee prices during the 1990s, coffee production remains a main economic activity for producers in Southeastern Mexico. This paper analyzes the coffee production system for 24 municipios, or districts, in Veracruz, Mexico during a five-year cropping period (1997-–2002). A stochastic frontier approach is used in order to estimate an input distance function and evaluate production efficiency during the period. Factors such as coffee quality and access to markets are tested in terms of their effect on efficiency. The results show the production process in these municipios, as measured by technical efficiency, seems to be stable over time despite of price fluctuations in the global market. Production of staple crops (corn) along with...

Tissue-culture propagated "Chicksaw" blackberry plants were set four feet apart in April of 2000 as part of a five-year trellising trial near Reidsville, Georgia. There were five treatments: an untrellised control, posts with plastic baling string on both sides, posts and three vertical wires, "raspberry" V trellis, and Limited Arm-Rotation Shift-Trellis (eliminated in 2003). There were four replications with twenty feet for each treatment per replication, for a total of 80 feet per treatment. Primocanes were tipped at 3.5 to four feet and re-tipped several times during the summer when new growth exceeded about 12 inches. Mature plant height at the end of the growing season was about five feet. Starting in the third growing season, yield data was collected...

Policies drain the North China Plain: Agricultural policy and groundwater depletion in Luancheng County, 1949-2000
Provedor de dados: 31
Autores: Kendy,   Eloise; Molden,   David J.; Steenhuis,   Tammo S.; Liu,   Changming; Wang,   Jinxia.
The report examines the relationships between agricultural policies in the North China Plain, the approaches to water management that evolved from them, the quantity of water that was actually used, and the consequent groundwater depletion beneath Luancheng County, Hebei Province, from 1949 to 2000. To systematically address these relationships, we use a comprehensive water-balance approach. Our results indicate that a single, longstanding policy-that of using groundwater to meet the crop-water requirements not supplied by precipitation-is responsible for the steady rate of groundwater decline.

Consistency of functional characteristics in wheat is a concern confronting buyers and sellers.  This research analyzes the cost and risk of different procurement strategies for importers.  A stochastic simulation model is used to determine the  probability of a functional characteristic being satisfied subject to quality targets and costs for alternative purchase strategies (purchase by protein only, variety, location, variety by location, or functional tests).  Joint probabilities of meeting specifications and costs were determined for the alternative purchase strategies.  Stochastic dominance was used to determine which purchase strategies dominate others, and stochastic efficiency was utilized to determine the degree of preference.  Results indicate...

This paper examines the problem of transforming information on fresh fruit and vegetable Arrivals to U.S. Metropolitan Statistical Areas into a distribution of products to larger geographical regions.  Three methods for the regional distribution of Florida-grown produce are compared.  A new method, which takes into account regional population sizes in the allocation of an area's produce to the region, is shown to produce allocations similar to those obtained through trucker surveys.  Finally, the new approach is applied to produce from other areas, and allocations to regions compared to that obtained using the Arrivals data only.

As part of an ACIAR-funded project on genetic diversity in wheat in Australia and China, Australian wheat breeders were surveyed to assess the importance of genetic diversity to breeders. This paper reports the findings of that survey, and identifies the key issues that concern wheat breeders. The issues addressed include the breeders’ attitude to diversity and the diversity available in their current gene pool. The sources of materials that breeders use to maintain and/or increase diversity in their programs are identified, and ways in which diversity influences breeding decisions are also examined. More importantly from the policy view point, survey responses identify changes over time in the environment in which breeders operate that affect the extent...

This paper uses extensive data on production outcomes for processing tomato growers in California to examine the efficacy of explicit incentives observed in grower-processor contracts. Our data include all deliveries of tomatoes to some 51 processors over a period of 7 years in which at least 65 unique types of contracts are employed. Results indicate that incentives account for a significant proportion of observed variation in production outcomes, and that complementarities across different sorts of "incentive instruments" play a prominent role in contract design. Although explicit incentives explain a substantial portion of the variation in production outcomes relative to that which could be explained by incentives (as captured by processor/year fixed...

UNCERTAINTY AND THE MANAGEMENT OF SALINITY WITH IRRIGATION WATER
Provedor de dados: 31
Autores: Feinerman,   Eli; Vaux,   Henry J., Jr.
The impact of uncertain salt balances in irrigate fields is assessed with a hydroeconomic model that incorporates the effects of salinity.  Uncertainty in two parameters that jointly determine root zone salinity is investigated and the conclusions prove to depend upon the way in which these parameters enter the mass-balance equation for soil salinity.  It is shown that water has a risk reducing marginal effect on output when growers are risk averse and, under certain conditions, when they are risk neutral.  The effects of prices, water quality, and crop salt sensitivity on the conclusions are analyzed and an empirical example is employed to illustrate the magnitude of the impacts.

The ability of agricultural policy makers to promote national development objectives requires an accurate and reasonably current picture of what crops farmers grow, what they eat, the importance of various crops in their incomes, and how they spend their money. In Zambia’s case, there is reasonably accurate information on production levels and trends in a specific set of crops grown by smallholder farmers, but very little knowledge of how important these specific crops are in smallholders’ total crop incomes, the importance of crop production in total smallholder incomes (which include livestock and non-farm activities), and how changes in crop prices affect smallholders’ welfare.

The proportion of smallholder households selling horticultural produce is very low suggesting that new demand points could enjoy substantial supply response if they link effectively to the smallholder sector. The small-scale traditional marketing system continues to dominate fresh produce flows in the country. Prices for consumers in this system are much lower, and quality is comparable and sometimes superior to supermarkets. Yet these markets suffer from serious structural problems due to a lack of public investment and little collaboration between public officials and traders in market management.

Food security in Uganda: a dilemma to achieving the millennium development goal
Provedor de dados: 31
Autores: Ssewanyana,   Sarah N.; Kasirye,   Ibrahim.
The status of food security in Uganda is worrying. The share of Ugandans suffering from food insecurity measured in terms of caloric intake is alarmingly high with low rates of income poverty. Based on the 2005/06 Uganda National Household Survey data, the study provides insights into access to food at household level. More importantly, the study shows that average caloric intake stood at 1,970 calories per person per day, which is below the minimum caloric requirement of 2,200 calories. As such, a population of 17.5 million Ugandans in 3.1 million households were unable to meet the minimum caloric requirement in 2006. This raises questions on whether Uganda will be able to achieve the Millennium Development Goal (MDG) 1: halving extreme poverty and hunger...

Deficiencies of micronutrients such as vitamin A are widespread, expecially in Africa. Biofortified crops such as maize, bred for high levels of provitamin A might offer a solution, but these crops are often bright orange, and African maize consumers prefer white. To estimate the consumers interest in orange biofortified maize, sensory evaluations were organized in rural Ghana with white, yellow and orange maize. The effect of information on willingness to pay for biofortification was estimated using a simulated radio message. Results indicate that color preferences are highly regional, wide variation exist within regions, and the provision of information is able to change these preferences. The color of biofortified maize should therefore not be seen as...

This paper aims to define this worldview, compare this with expectations of marketing intermediaries down the vegetable supply chain, and assess the gaps between these views. Discrepancies between and among the definitions of the different groups affect the entire chain because of incompatible decisions in production, marketing and quality management. These decisions contribute to the efficiency or inefficiency of the entire chain. Introduction

Cotton in Zambia: 2007 Assessment of its Organization, Performance, Current Policy Initiatives, and Challenges for the Future
Provedor de dados: 31
Autores: Tschirley,   David L.; Kabwe,   Stephen.
Cotton is one unquestioned success of Zambia’s turn towards a market economy. After liberalization in late 1994, production rose from 20,000 mt to over 100,000 mt in the 1998 harvest year. After collapsing to less than 50,000 mt in 2000, it has risen steadily, nearing 200,000 mt in 2005. Over 2002-2005, exports of cotton lint were first among all agricultural exports in value, 30% higher than any other agricultural export (Export Board of Zambia 2006). The closest competitor to cotton during this time –raw cane sugar –is primarily produced on large operations, while cotton is almost entirely a smallholder crop. Its potential role in poverty alleviation and food security is, thus, very large. The success of this sector has been achieved despite persistent...

Fruit Flies: Solutions to Food Crop Losses and Opportunities for Business Development
Provedor de dados: 31
Autores: Drew,   Dick.
Fruit flies are the major insect pests of fruit and vegetable production, worldwide. In developing countries, fruit crop losses are so large that they contribute significantly to reduced household food security, poor human nutrition and poverty. In addition to the direct crop losses, many countries lose export trade opportunities if they have major pest fruit fly species, while others spend considerable sums on quarantine detection and eradication procedures in order to remain free of fruit fly. Indeed, fruit flies rate with some of the major animal diseases in terms of economic losses and quarantine problems.

RATIONAL EXPECTATIONS ESTIMATION OF GEORGIA SOYBEAN ACREAGE RESPONSE
Provedor de dados: 31
Autores: Ahouissoussi,   Nicolas B.C.; McIntosh,   Christopher S.; Wetzstein,   Michael E.
The general method of moments procedure is used for estimating a soybean acreage response function assuming the producers hold rational expectations. Results indicate that soybean, corn, and wheat futures prices, lagged acreage, and government programs are significant factors for determining soybean plantings. Implications of the results are that crop acreage selection by Georgia producers is not very responsive to demand shocks. Thus, producers in other regions are more likely to absorb impacts from these shocks on crop acreage selection.

An economic analysis of the possibility of reducing pesticides in French field crops
Provedor de dados: 31
Autores: Jacquet,   Florence; Butault,   Jean-Pierre; Guichard,   Laurence.
The paper aims to study the effects of reducing pesticide use by farmers in the arable sector in France and the feasibility of a policy target of reducing pesticide use by half. The originality of the approach is to combine statistical data and expert knowledge to describe low-input alternative techniques at the national level. These data are used in a mathematical programming model to simulate the effect on land use, production and farmers’ income of achieving different levels of pesticide reduction. The results show that reducing pesticide use by 30% could be possible without reducing farmers’ income. We also estimate the levels of tax on pesticides necessary to achieve different levels of reduction of pesticide use and the effect of an incentive...

Forecasting the market outlook for the South African maize and sorghum sector using econometric modeling
Provedor de dados: 31
Autores: Poonyth,   Daneswar; van Zyl,   Johan; Meyer,   Ferdinand H.
In this study, an econometric model of the South African maize and sorghum sector is estimated. Using the developed model, a market outlook for the two major grain sectors – maize and sorghum - for 1999/00 to 2006/07, is generated under the specified assumptions. Results indicate that for both maize and sorghum, consumption will gradually increase over time. In spite of varying areas of maize and sorghum being harvested, total production will also gradually increase over time due to increases in particularly yields.

Autores: Butcher,   G.V; Ford,   Stuart.
The 2007-08 drought affected a large area of New Zealand. This paper describes the analytical framework used to estimate the associated regional and national economic impacts. Results suggest that calculating drought economic impacts by applying standard farming industry multipliers to changes in farm gate output can greatly overstate both regional and national economic impacts. Calculating impacts using differences between forecast and actual farm production and expenditure by farm type is both feasible and produces far more reliable impact estimates.

Autores: Welch,   J. Mark; Lyford,   Conrad P.
Increasing competition from foreign manufacturers threatens the viability of textile producers in the United States. This paper evaluates the U.S. competitive position in the cotton yarn segment using established quantifiable measures and provides an overall competitive assessment. The measures employed show the United States to be at a relative competitive disadvantage when compared to major international producers of cotton yarn. However, the margin of this competitive disadvantage is shown to be relatively small and in some cases, decreasing.

Technical Efficiency Effects of Technological Change: Another Perspective on GM Crops
Provedor de dados: 31
Autores: Weaver,   Robert D.; Curtiss,   Jarmila; Brümmer,   Bernhard.
An important approach to reducing persistent technical inefficiency is through technical change. This paper considers the case of genetically modified crop production. A stochastic frontier approach is used to examine how a drastic change from non-GM to GM technology effects the position of the production frontier as well as the extent and nature of technical inefficiency. A one-step method is applied to consider firm-level effects on technical inefficiency. Using soybean production from the U.S. we find that GM technology improves productivity and reduces technical inefficiency though these effects vary across farm characteristics.

Changing Incentives to Sow Cotton for African Farmers: Evidence from the Burkina Faso Reform
Provedor de dados: 31
Autores: Kaminski,   Jonathan.
Over the last 10 years, Burkina Faso has experienced a reform of its cotton sector, and is now the largest African cotton producer and exporter. The cotton ”boom” consisted of a rapid expansion of cotton areas through the growth of land shares allocated to cotton (and new producers), together with an overall increase in total cultivated land. In this paper, we present an empirical framework to determine the contribution of total farmland changes in the increase of land dedicated to cotton, where both processes are represented by ordered endogenous variables. We then analyze data that we collected in rural Burkina Faso in March 2006 within this framework. From measurable indicators of farmer behavior and variables that measure farmer statements for the...

This paper outlines the role of improved soil fertility in the process of structural transformation, and examines specific financial, economic, social, and political arguments in favor of promoting increased fertilizer use, particularly in smallholder farming systems. This paper draws experiences and insights from the literature on which policies and programs appear to work best and which least well in providing a consistent and growing supply of fertilizer to smallholders. Particular attention is given to addressing the question of fertilizer subsidies: Under what circumstances are they warranted and what form should they take, if and when they are implemented?

Assisting decision-making in Queensland barley production through chance constrained programming
Provedor de dados: 31
Autores: Gali,   Jyothi; Brown,   Colin G.
A chance constrained programming model is developed to assist Queensland barley growers make varietal and agronomic decisions in the face of changing product demands and volatile production conditions. Unsuitable or overlooked in many risk programming applications, the chance constrained programming approach nonetheless aptly captures the single‐stage decision problem faced by barley growers of whether to plant lower‐yielding but potentially higher‐priced malting varieties, given a particular expectation of meeting malting grade standards. Different expectations greatly affect the optimal mix of malting and feed barley activities. The analysis highlights the suitability of chance constrained programming to this specific class of farm decision problem.

Using Ecological Indices and Economics to Explain Diversity in a Wheat Crop: Examples from Australia and China
Provedor de dados: 31
Autores: Smale,   Melinda; Meng,   Erika C.H.; Brennan,   John P.; Hu,   Ruifa.
Spatial diversity indicators may serve policymakers as they seek to manage crop genetic diversity and externalities associated with diffusion of some genetically modified crops. This paper adapts ecological indices of spatial diversity to area distributions of modern wheat varieties in contrasting production systems of Australia and China. The variation in three concepts of spatial diversity—richness, abundance, and evenness—is explained using Zellner’s seemingly unrelated regression (SUR). Determinants of wheat diversity differ by concept, but include variety traits other than yield potential, environmental factors, and policies affecting the supply of varieties, research spill-ins, and market liberalization.

Monsanto's Adventures in Zulu Land: Output and Labour Effects of GM Maize and Minimum Tillage
Provedor de dados: 31
Autores: Gouse,   Marnus; Piesse,   Jenifer; Thirtle,   Colin G.
The only commercial genetically modified (GM) subsistence food crop is white maize in South Africa, which was released in 2001/2. This paper reports on the performance of insect resistant (Bt) white maize grown by smallholders in Hlabisa, KwaZulu Natal, where the other development is minimum tillage. The results show that, contrary to many inflated claims, in the dry 2003/4 season, there was no significant difference between the yield per kg of seed for Bt and conventional maize, due to very low stalk borer infestation levels. Farmers who planted Bt maize in 2003/2004 were thus worse off as they paid more for seed and obtained no benefit. This is measured using efficiency scores from a stochastic frontier analysis. These results conflict with the yield per...

This study is part of a larger effort to explore the impact of agricultural research on poverty reduction. It examines the diffusion and impact of hybrid maize in selected resettlement areas of rural Zimbabwe, paying particular attention to varieties made widely available from the mid-1990s onwards. While “Zimbabwe’s Green Revolution” of the early 1980s was characterized by the widespread adoption of hybrid maize varieties and significant increases in yields, the subsequent diffusion of newer varieties occurred more slowly and had a more modest impact. Several factors account for this. Government now plays a much-reduced role and one that increasingly focuses on “better farmers.” Private-sector institutions that have entered the maize sector operate mainly...

Fertilizer Impacts on Soils and Crops of Sub-Saharan Africa
Provedor de dados: 31
Autores: Weight,   David; Kelly,   Valerie A.
Successful agricultural development has resulted in substantial alleviation of poverty and food security in Asia and Latin America since the 1960s. Much of this success can be attributed to the introduction of high-yielding varieties of crops, especially wheat and rice, which have addressed the constraints faced by farmers using traditional varieties. In Sub-Saharan Africa (SSA), however, productivity levels have remained stagnant despite the introduction of new crop germplasm. In recent years, scientists have recognized that low soil fertility is the primary constraint blocking agricultural development in SSA. Major findings from this study may be summed up in five key points. Declining fertility and SOM in SSA are a result primarily of...

This paper uses a random sample of 881 farmers drawn from eastern and western Kenya to examine the prevalence and drivers of seed and pollen mediated geneflow in the two major sorghum growing regions. It employs both qualitative and quantitative techniques to assess farmers’ awareness of wild sorghum varieties, the practices they use in maintaining varietal purity and the conditioners of their success in maintaining the purity of cultivated varieties. The study finds that, among others, cultural differences, agro-climate and poverty affect the awareness, practices used in maintaining varietal purity and farmers’ success in doing so. These findings have implication for biosafety and policy in Kenya due to the clamour to introduce genetically modified...

DEMAND, SUPPLY AND PRICE PREDICTION OF RICE IN TAIWAN FROM 1976 TO 1985
Provedor de dados: 31

Taiwan is located in the subtropical area of the Far East.  With the benefit of suitable weather, average temperature just under 71 F in the north and nearly 76 F in the south, and with the yearly precipitation around 75 inches, rice has been the self sufficient staff crop in Taiwan.  Even in the early eighteenth century, Taiwan exported rice to support the supply in Mainland China.  Rice is a necessity for Taiwanese.  A sufficient supply and stabilization of its price are relevant to the whole economy and society.  Because of the development of industry and economic growth, a lot of cultivated land has been transferred from rice production to industrial or architectural utilization under the principle of comparative advantage since 1958.

Irrigated agriculture has increased steadily in Syria over the last decades, almost doubling since 1985. This mounting pace has responded to the nation’s food security policy objectives to satisfy the food production needs of an increasing population that features one of the largest growth rates in the world, namely 3,50 percent in 1985 and still 3,39 percent in 2007. Total expenditures for irrigated agriculture accounted for almost 70 percent of all expenditures in agriculture. Sustainable irrigation water policies aimed at increasing the efficiency of water use in agriculture and at conserving water resources by reducing future consumption.

Autores: Hughes,   David W.; Brown,   Cheryl; Miller,   Stacy; McConnell,   Tom.
Farmers’ markets presumably benefit local economies through enhanced retention of local dollars. Unlike other studies, the net impact of farmers’ markets on the West Virginia economy is examined. Producer survey results are used in estimating annual direct sales ($1.725 million). Using an IMPLAN-based input-output model, gross impacts are 119 jobs (69 full-time equivalent jobs) and $2.389 million in output including $1.48 million in gross state product (GSP). When the effect of direct revenue losses are included (primarily for grocery stores), the impact is reduced to 82 jobs (43 full-time equivalent jobs), $1.075 million in output, and $0.653 million in GSP.

Alternative Hedging Strategies in Maize Production to Cope with Climate Variability and Change
Provedor de dados: 31
Autores: Fuhrer,   Jurg; Beniston,   Martin; Calanca,   Pierluigi; Torriani,   Daniele Simone.
Climate change with increasing climate variability is likely to alter risks in agricultural production. The effectiveness of using weather derivatives to hedge against drought risks for rain-fed grain maize production was investigated for current (1981-2003) and future (2070- 2100) climates in Switzerland. The climate change scenario was extrapolated from results of a regional climate model (HIRHAM4) based on the IPCC A2 emission scenario. In addition, a sensitivity analysis was performed by varying the mean and variance of the initial probability space for the seasonal precipitation sum. Profits and risks with and without hedging were compared using the analogy of the value-at-risk measure (VaR), i.e., a quantile-based measure of risk. A Monte Carlo chain...

FINANCIAL RISK IN COTTON PRODUCTION
Provedor de dados: 31
Autores: Wilson,   Paul N.; Gundersen,   Carl E.
Risk analysis continues to emphasize price and yield variability as the principal components of the decision-maker's risk environment.  This research demonstrates the relative importance of financial risk for a representative cotton farm in Arizona.  For highly leveraged operations, financial risk may account for 70 percent of the total risk faced by the producer.  Implications for future risk analysis are discussed in light of these findings.

NONCONSTANT PRICE EXPECTATIONS AND ACREAGE RESPONSE: THE CASE OF COTTON PRODUCTION IN GEORGIA
Provedor de dados: 31
Autores: Parrott,   Scott D.; McIntosh,   Christopher S.
An adaptive regression model is used to examine the relative importance of cash and government support prices in determining cotton production over time. The results show that the cash price is more important as a source of price information for cotton producers than the government program price. The cash price was shown to have a greater influence on acreage response in every year, including periods thought to be dominated by government commodity programs.

The Choice of Tillage, Rotation, and Soil Testing Practices: Economic and Environmental Implications
Provedor de dados: 31
Autores: Wu,   JunJie; Babcock,   Bruce A.; Lakshminarayan,   P.G.
Which management practices farmers adopt has a significant effect on agricultural pollution. Research has analyzed factors influencing adoption of a single management practice. But often adoption decisions about many practices are made simultaneously, which suggests use of a polychotomous-choice model to analyze decisions. We apply such a model to the choice of alternative management practices on cropland in the Central Nebraska Basin and control for self-selection and the interaction among alternative practices. We use the results of the choice model to estimate the economic and environmental effect so adopting alternative combinations of management practices.  Our results suggest that crop rotation and soil N testing are complementary practices, perhaps...

Solving the Problem of Sustainable Use of Bt Crops
Provedor de dados: 31
Autores: Dun,   Zhe; Mitchell,   Paul D.
Transgenic plants producing insecticidal protein derived from Bacillus thuringiensis (Bt) have been widely adopted since their commercial introduction in 1996. The widespread adoption of such plants has reduced use of conventional insecticides while attaining yield gains, thus providing economic, environmental and human health benefits. However, the benefits from Bt crops will be reduced or even eliminated if pests develop resistance to these toxins so that Bt crops are less or no longer effective. Although field resistance to Bt crops has not yet been found in the continental U.S., resistance to Bt sprays has been found in diamondback moth and greenhouse populations of cabbage looper. Hence, considerable attention has been devoted to developing management...

Autores: Fuglie,   Keith O.
We use an index number approach to measure total factor productivity (TFP) growth in Indonesian crop and livestock agriculture between 1961-2000. A Tornqvist index is developed to minimize biases that may result from relative price changes in factor and output weights. The results indicate that agricultural TFP growth accelerated in the 1970s but was halted in the late 1990s. Agricultural productivity growth was not limited to rice but also extended to other food and horticultural crops.

VALUATION OF NEW SPRING WHEAT VARIETIES: TRADEOFFS FOR GROWERS AND END-USERS (SUMMARY)
Provedor de dados: 31
Autores: Dahl,   Bruce L.; Wilson,   William W.; Johnson,   D. Demcey; Nganje,   William E.
Variety release decisions involve a number of tradeoffs, usually between grower and end-user characteristics as well as significant uncertainties about agronomic, quality, and economic variables.  In this study, methodologies were developed to value tradeoffs for grower and end-user characteristics for wheat.  The models capture effects of variability in agronomic, quality, and economic variables.   The models were applied for three experimental varieties which have since been released and for two hypothetical varieties.  Results indicate two of the experimental varieties provide improvements in grower and end-use value over most of the incumbents.   Comparison of a risk adjusted portfolio model consisting of characteristics of end-use and grower values...

Fertilizer Use and Maize Production in Sub-Saharan Africa
Provedor de dados: 31
Autores: Heisey,   Paul W.; Mwangi,   Wilfred.
In sub-Saharan Africa, greater use of mineral fertilizers is crucial to increasing food production and slowing the rate of environmental degradation. Regional growth rates in fertilizer consumption have never been particularly high, in part because the real price of fertilizer is higher in Africa than in many other developing regions. As subsidies have been removed and exchange-rate distortions corrected over the past decade or more, relative prices paid by farmers have risen to reflect more closely the economic cost of fertilizer. Consumption growth has thus slowed even more.  Nonetheless, during the period of declining growth in consumption, fertilizer use on cereals, particularly maize, has become relatively more important than use on cash crops....

Autores: Hock,   Cricket; Naseem,   Anwar; Hossain,   Ferdaus; Pray,   Carl E.
The application of modern biotechnology to plant breeding is considered to be more efficient and quicker than conventional breeding techniques in the development of new and more resilient crop varieties. To test the impact that biotechnology is having on a industrial plant breeding activities, we relate firm level Plant Variety Protection Certificate (PVPC) applications to corresponding expenditure on research and development (R&amp;D), agricultural biotechnology patents applications, field trials of genetically modified crops, firm structure, as well as industry specific characteristics. Regression results indicate agbiotech activities are directly related to PVP applications, hence the creation of new plant varieties.

Effective information and the influence of an extension event on perceptions and adoption
Provedor de dados: 31
Autores: Llewellyn,   Rick S.; Lindner,   Robert K.; Pannell,   David J.; Powles,   Stephen B.
Perceptions are known to play an important role in the innovation adoption decision. Once influential perceptions have been identified, there is the potential for information to influence adoption by changing these perceptions. In this paper, the influence of an extension workshop targeting grain growers’ perceptions known to be associated with the adoption of integrated weed management and herbicide resistance management has been measured using regression analysis. Consistent with a Bayesian learning framework, the greatest influence on grower perceptions and intended adoption behaviour was observed where information could be delivered with a high degree of certainty and validity.

In order to evaluate food security, technology potential and the environmental impacts of production in a strategic and regional context, it is critical to have reliable information on the spatial distribution and coincidence of people, agricultural production, and environmental services. This paper proposes a spatial allocation model for generating highly disaggregated, crop-specific production data by a triangulation of any and all relevant background and partial information. This includes national or sub-national crop production statistics, satellite data on land cover, maps of irrigated areas, biophysical crop suitability assessments, population density, secondary data on irrigation and rainfed production systems, cropping intensity, and crop prices....

ESTIMATING SITE-SPECIFIC NITROGEN CROP RESPONSE FUNCTIONS: A CONCEPTUAL FRAMEWORK AND GEOSTATISTICAL MODEL
Provedor de dados: 31
Autores: Malzer,   Gary L.; Hurley,   Terrance M.; Kilian,   Bernard.
Confirming the precision agriculture hypothesis for variable rate nitrogen applications (VRA) is challenging.  To confront this challenge, researchers have used increasingly sophisticated statistical models to estimate and compare site-specific crop response functions (SSCRFs).  While progress has been made, it has been hampered by the lack of a conceptual framework to guide the development of appropriate statistical models.  This paper provides such a framework and demonstrates its utility by developing a heteroscedastic, fixed and random effects, geostatistical model to test if VRA can increase nitrogen returns.  The novelty of the model is the inclusion of site, spatial, treatment, and treatment strip heteroscedasticity and correlation.  Applied to data...

DO CORN FARMERS HAVE TOO MUCH FAITH IN THE SUGAR PROGRAM?
Provedor de dados: 31
Autores: Rendleman,   C. Matthew; Hertel,   Thomas W.
Corn producers frequently have been told that the sugar program provides an important stimulus to corn demand through its positive influence on the high fructose corn syrup sector. In this article we qualify the extent of this support and find it to be very small- not more than 3 cents per bushel, and probably less. Previous studies have overstated this effect due a lack of attention to the interindustry linkages in the sweetener complex.

Drought is a major constraint affecting rice production especially in rainfed areas of Asia. Despite its importance in rice growing areas, the magnitude of economic losses arising from drought, its impact on farm households and farmers' drought coping mechanisms are poorly understood. This paper provides insights into these aspects of drought based on a cross-country comparative analysis of rainfed rice growing areas in China, India and Thailand. The economic cost of drought is found to be substantially higher in eastern India than in the other two countries. Higher probability and greater spatial covariance of drought and less diversified farming systems with rice accounting for a large r share of household income are likely to be the main reasons for...

Upon identification of the yield moments under a variety of climate and irrigation regimes, we utilize maximum entropy techniques to analyze the distributional impacts from switching regimes. We consider the case of Arkansas, Mississippi, and Texas upland cotton to demonstrate how climate and irrigation affect the shape of the yield distribution, and compare our findings to other moment based approaches.

Valuing Catastrophic Citrus Losses
Provedor de dados: 31
Autores: Adams,   Damian C.; Kilmer,   Richard L.; Moss,   Charles B.; Schmitz,   Andrew.
Courts are often required to estimate changes in welfare to agricultural operations from catastrophic events. For example, courts must assign damages in lawsuits, such as with pesticide drift cases, or determine "just compensation" when the government takes private land for public use, as with the removal of dairy farms from environmentally sensitive land or destruction of canker-contaminated citrus trees. In economics, the traditional method of quantifying producer losses is estimating changes in producer welfare, but courts rarely use this method. Instead, they turn to substitute valuation methods that may not fully capture welfare changes, such as changes in land value, tree replacement value, and total revenue.

GROUNDNUT TRADE LIBERALIZATION: A SOUTH-SOUTH DEBATE?
Provedor de dados: 31
Autores: Beghin,   John C.; Diop,   Ndiame; Matthey,   Holger; Sewadeh,   Mirvat.
We use a new partial-equilibrium, multi-market international model to analyze trade and agricultural policies affecting markets for peanut/groundnut products. The model covers four goods in thirteen countries/regions, including a large set of developing countries. Welfare is evaluated by looking at consumers' equivalent variation, quasi-profits in farming, quasi-profits in crushing, and taxpayers' revenues and outlays implied by distortions. We calibrate the model on recent historical data and current policy information. We analyze several groundnut trade liberalization scenarios in deviation from the recent historical baseline. Trade liberalization in groundnut markets has a strong South-South dimension, opposing India and, to a lesser extent, China to...

Economic analysis of integrated weed management strategies for annual barnyardgrass (Echinochloa crus-galli complex) in Philippine rice farming systems
Provedor de dados: 31
Autores: Beltran,   Jesusa C.; Pannell,   David J.; Doole,   Graeme J.; White,   Benedict.
This paper describes a dynamic simulation model that has been developed to provide a comprehensive assessment of integrated weed management programmes for the control of annual barnyardgrass (Echinochloa crus-galli complex) in Philippine rice farming systems. The main outputs of the model include weed seed and plant densities and seasonal and annualised profit over the simulated planning horizon. Model output emphasises the substantial economic benefits associated with effective long-term weed management strategies. In addition, a mixture of chemical and non-chemical treatments provides good weed control in rice crops, and maximises long-term profit for systems where the main weed is annual barnyardgrass. However, the performance of this strategy is...

Technical Efficiency of Grain Production in Ukraine
Provedor de dados: 31
Autores: Kurkalova,   Lyubov A.; Jensen,   Helen H.
A stochastic production frontier model with technical inefficiency effects is estimated on a representative sample of Ukrainian state and collective grain-producing farms. Technical efficiency declined from 1989 to 1992. More experienced managers were found to be more productive, with the effect of experience diminishing with age. We found that on-farm provision of production infrastructure was associated with higher efficiency, a result supporting the hypothesis that disorganization causes output to decline in transition economies.

Autores: Pender,   John L.; Abdoulaye,   Tahirou; Ndjeunga,   Jupiter; Gerard,   Bruno; Kato,   Edward.
This study investigated the impacts of access to inventory credit, input supply shops, fertilizer microdosing demonstrations, and other factors on farmers’ use of inorganic fertilizer and other inputs in Niger and on crop yields. We found that access to inventory credit and input supply shops has increased the use of inorganic fertilizer and seeds and that microdosing demonstrations have increased the use of inorganic fertilizer. Ownership of traction animals and access to off-farm employment have also contributed to the use of inorganic fertilizer, while larger farms use less fertilizer and labor per hectare. The impacts of these interventions and technologies depend on the crop mix. Inorganic fertilizer has a positive impact on millet and millet–cowpea...

Cotton Futures Dynamics: Structural Change, Index Traders and the Returns to Storage
Provedor de dados: 31
Autores: Power,   Gabriel J.; Robinson,   John R.C.
The commodity bull cycle of 2006-2008 and subsequent dramatic price decline have been a source of hardship for traditional commodity market participants such as producers and merchant/shippers. The usefulness of futures markets has been called into question, especially given that some market movements did not appear to be justified by economic fundamentals. An emerging research literature examines the possible influence of futures traders, and particularly the non-traditional Index Traders, on the well-functioning of futures markets and underlying commodity markets. Cotton is a relatively under-studied commodity that is of particular importance for producers in the South and Southwest. To this end, this paper asks the following questions: (1) What role...

World Soybean Demand: An Elasticity Analysis and Long-Term Projections
Provedor de dados: 31
Autores: Masuda,   Tadayoshi; Goldsmith,   Peter D.
Soybeans are one of the most valuable crops in the world and are characterized by their multi-purpose uses: food, feed, fuel and other industrial usages such as paint, inks, and plastics.  Out of 183.9 million tons of world supply/demand of soybeans in 2001-03 year, about 10% of them were directly consumed as food (5.9%) or feed (3.8%) but 84.2% of them were crushed into soyoil and soymeal.  Soyoil is mainly processed to vegetable oil for human consumption and recently used as a biodiesel feedstock.  Soymeal is used not only as feed for livestock (especially for pork and poultry due to its low fiber level) and aquaculture, but also as a good source of protein for the human diet in a variety of forms in different cultures.

Investment in Water Saving Technology on Horticultural Farms
Provedor de dados: 31
Autores: Mallawaarachchi,   Thilak; Hall,   Nigel H.; Phillips,   Brian.
A long run programming model for analysing investment behaviour on perennial crop farms is formulated and applied to citrus and wine grape producing farms in the Murumbidgee Irrigation Area. Prices and technological parameters are defined exogenously, while the optimal replanting pattern of the crops and the optimal mix of irrigation techniques are determined endogenously. The model is used to examine likely investment in water saving irrigation technology at different crop prices and input costs. The results indicate that such investment is a profitable option at current water charges, particularly for those farmers with access to off-farm employment However, the adoption decision will be highly sensitive to potential cost savings.

Crop switching as a strategy for adapting to climate change
Provedor de dados: 31
Autores: Kurukulasuriya,   Pradeep; Mendelsohn,   Robert.
This paper examines the impact of climate change on primary crops grown in Africa. An innovative approach is presented that bridges the gap between agro-economic and traditional Ricardian models. We label it a ‘structural Ricardian model’. It first captures the type of crop a farmer will select and then examines the conditional net revenue of that crop. The model is estimated using a sample of over 5000 farmers across 11 countries in Africa. The analysis finds that farmers shift the crops they plant to match the climate they face. Studies that fail to account for crop switching will overestimate the damages from climate change and underestimate the benefits.

How a National Carbon Policy Could Affect Grain Variety Selection:  The Case of Rice in Arkansas
Provedor de dados: 31
Autores: McFadden,   Brandon R.; Nalley,   Lawton Lanier; Popp,   Michael P.
This study conducts a life cycle assessment (LCA) of carbon emissions and estimates the carbon sequestered in 14 commonly sown rice varieties across the Arkansas Delta.  Given the uncertainty regarding future carbon legislation, and increased consumer and industry demand for “greener” products, this study estimates how potential carbon policies would affect rice cultivar selection Hybrid rice varieties, given their higher yield and higher yield per unit of green house gas (GHG) emission, are better positioned to take advantage of any increase in consumer demand for “greener” products and/or absorb any government policy better than conventional rice cultivars.

Eighty-nine percent of American households were food secure throughout the entire year in 2005, meaning that they had access, at all times, to enough food for an active, healthy life for all household members. The remaining households were food insecure at least some time during that year. The prevalence of food insecurity declined from 11.9 percent of households in 2004 to 11.0 percent in 2005, while the prevalence of very low food security remained unchanged at 3.9 percent. This report, based on data from the December 2005 food security survey, provides the most recent statistics on the food security of U.S. households, as well as on how much they spent for food and the extent to which food-insecure households participated in Federal and community food...

Testing Day’s Conjecture that More Nitrogen Decreases Crop Yield Skewness
Provedor de dados: 31
Autores: Du,   Xiaodong; Hennessy,   David A.; Yu,   Cindy L.
While controversy surrounds skewness attributes of typical yield distributions, a better understanding is important for agricultural policy assessment and for crop insurance rate setting. Day (1965) conjectured that crop yield skewness declines with an increase in low levels of nitrogen use, but higher levels have no effect. In a theoretical model based on the law of the minimum (von Liebig) technology, we find conditions under which Day’s conjecture applies. Employing four experimental plot datasets, we investigate the conjecture by introducing (a) a flexible Bayesian extension of the Just-Pope technology to incorporate skewness, and (b) a quantile-based measure of skewness shift. For corn yields, the Bayesian estimation provides strong evidence in favor...

This study undertaken in Punjab on kinnow mandarin has suggested to include marketing loss in the estimation of marketing margins, price spread and efficiency and has used a modified formula for it. It has been observed that a majority of kinnow producers sell their orchards to the pre-harvest contractors/ traders at different stages. The aggregate post-harvest losses from orchards to consumers in kinnow in two different markets ranges from 14.87 per cent in Delhi market to 21.91 per cent in Bangalore market. It has indicated the necessity of establishing kinnow processing industries for development of value-added ready-to-serve (RTS) quality products, minimizing post-harvest losses and providing remunerative price to the producers.

SPATIAL REGRESSION MODELS FOR YIELD MONITOR DATA: A CASE STUDY FROM ARGENTINA
Provedor de dados: 31
Autores: Lambert,   Dayton M.; Lowenberg-DeBoer,   James; Bongiovanni,   Rodolfo.
Precision agricultural technology promises to move crop production closer to a manufacturing paradigm, but analysis of yield monitor, sensor and other spatial data has proven difficult because correlation among neighboring observations often violates the assumptions of classical statistical analysis. When spatial structure is ignored variance estimates tend to be inflated and significance levels of test statistics are reduced. The gap between data analysis and site-specific recommendations has been identified as one of the key constraints on widespread adoption of precision agriculture technology. This paper compares four approaches that explicitly incorporate spatial correlation into regression models: (1) a spatial econometric approach; (2) a polynomial...

COCOA PRODUCTION PROSPECT IN TOGO
Provedor de dados: 31
Autores: Assiongbon,   Ekoue K.
Cocoa has made an important contribution to economic development in Togo.  Until recently, virtually all of Togo's exports were agriculture, mainly:  cocoa and coffee.  In 1961, phosphate exports began, and by 1965 became the leading export commodity.  Even after the discovery and production of phosphate minerals, agriculture exports, however, continue to provide more than 30 percent of all foreign exchange and to employ about 75 percent of the active population.  Cocoa and coffee represent 70 percent of agricultural exports and cocoa alone provided an average of 27 percent of recorded export earnings between 1966 and 1975.  Since 1965, the agriculture sector has been accorded top priority in the national development plan.  However, this proclamation has...

Autores: Kipperberg,   Gorm; Bond,   Craig A.; Hoag,   Dana L.
This paper analyzes Colorado Corn producers’ preferences over both private- and environmental public-good production system attributes. Current production practices are characterized by intensive water and chemical use, resulting in non-point source pollution to water bodies as well as soil erosion problems. Data from a stated preference survey are employed to analyze key attributes of experimentally configured irrigation systems, proposed as alternatives to current practices. Panel mixed logit estimations find positive preferences for profit, risk reduction, and, importantly, systems with less environmental impact in terms of nitrate leaching and soil erosion. The results also find presence of significant preference heterogeneity and a complementary...

Portfolios of Agricultural Market Advisory Services: How Much Diversification is Enough?

Autores: Cabrini,   Silvina M.; Stark,   Brian G.; Irwin,   Scott H.; Good,   Darrel L.; Martines-Filho,   Joao Gomes.
This study analyzes the potential risk-reduction gains from naïve diversification among market advisory services for corn and soybeans.  The total possible decrease in risk through naïve diversification is small, mainly because advisory prices are highly correlated on average.  Moreover, because marginal risk-reduction benefits decrease rapidly with size and the cost of holding the portfolios increases linearly due to services’ subscription fees, it is optimal to limit portfolio size to a few advisory programs.  Based on certainty equivalent measures and two representative risk-aversion levels, preferred portfolio sizes are between one and three programs.

Market-Based Instruments for the Optimal Control of Invasive Insect Species: B. Tabaci in Arizona
Provedor de dados: 31
Autores: Richards,   Timothy J.; Ellsworth,   Peter; Tronstad,   Russell; Naranjo,   Steve.
Invasive insect species represent perhaps one of the most significant potential sources of economic risk to U.S. agricultural production. Private control of invasive insect species is likely to be insufficient due to negative externality and weaker-link public good problems. In this study, we compare a system of Pigouvian taxes with tradable permits for invasive species control. While the emissions control literature shows that taxes are preferred to permits under cost uncertainty, invasive-species control involves correlated cost and benefit uncertainty. Hence, we expect a quantity-based system to be preferred. Monte Carlo simulations of optimal steady-state outcomes confirm our expectations.

The objective of this paper is to characterize the production of roses at the region of Barbacena and to identify its transaction attributes, that is, asset specificity, transaction frequency, and uncertainty. The research is based on the theoretical framework of the New Institutions Economy which allows the use of qualitative methods in order to understand in depth the study object. The results have shown that rose producers in the region of Barbacena seek to demand the requirements of their customers, but they perceive the need of improvement in the productive chain through associations and contractual relations, informal ones included, among the agents involved in the agribusiness of roses.

Determinants of Improved Maize Seed and Fertilizer Use in Kenya: Policy Implications
Provedor de dados: 31
Autores: Ouma,   James Okuro; De Groote,   Hugo; Owuor,   George.
Maize is a key food crop in Kenya. While maize yields increased from 1.25 t ha-1 in early 1960s to over 2 tonnes in 1982, they fell below 1.5 t ha-1 in 2000. Given the limited land area, there is no doubt that Kenya will have to rely more on modern technologies for increased yields .Use of improved maize varieties and fertilizers will therefore continue to be critical inputs for improving productivity. To improve production, it is important to understand factors determining adoption and intensity of use of modern technologies. A stratified 2-stage sampling design was used to select 1800 households, subsequently interviewed by means of structured questionnaire. Econometric models were used to explore factors influencing adoption and intensity of use of the...

Price transmission in the Hungarian vegetable sector

Autores: Bakucs,   Lajos Zoltan; Ferto,   Imre; Szabo,   Gabor G.
In this paper we analyse price transmission for the carrot, parsley, tomato, green pepper and potato markets. Although there is a dual farm structure dominated by small individual farms, our results imply that price information flows from the producer to the retail level for potatoes, parsley and carrots. Our results also suggest that farmers do not merely accept prices, but can actually influence market prices. Tomato and green pepper prices have large transmission elasticities, and causality runs from the retail to producer level. It therefore follows that tomato and green pepper producers tend to accept prices and that the sector’s prices are determined by upper market levels (processors, wholesalers, retailers). These results are reinforced by the fact...

Peasants and plantations in the Sri Lankan tea sector: causes of the change in their relative viability
Provedor de dados: 31
Autores: Herath,   Deepananda P.B.; Weersink,   Alfons.
In contrast to the increasing trend in farm size found in most agricultural sectors, the absolute number of producers and relative share of total production from small farms growing green leaf tea in Sri Lanka have increased significantly over time. The boom in peasant production and the corresponding decline in plantations are due to the same general drivers explaining the increase in farm size elsewhere. Government programs and price effects that reduced revenue uncertainty and relative costs of production have enhanced the competitive position of small farmers relative to large estates.

THE ADOPTION OF IPM TECHNIQUES BY VEGETABLE GROWERS IN FLORIDA, MICHIGAN AND TEXAS
Provedor de dados: 31
Autores: Fernandez-Cornejo,   Jorge; Beach,   E. Douglas; Huang,   Wen-Yuan.
Factors influencing the adoption of Integrated Pest Management (IPM) techniques are studied using survey data from individual vegetable producers from Florida, Michigan, and Texas.  Farmers who adopt IPM tend to be less risk averse and use more managerial time on farm activities than nonadopters.  Adopters are also more likely to operate large, irrigated farms and use more family labor.  Locational factors and the type of crop grown are also influential in IPM adoption.  The analysis uses a logit framework and introduces adopter categories first conceptualized by rural sociologists.

Identification of stochastic processes for an estimated icewine temperature hedging variable
Provedor de dados: 31
Autores: Cyr,   Don; Kusy,   Martin.
Weather derivatives are a relatively new form of financial security that can provide firms with the ability to hedge against the impact of weather related risks to their activities.  Participants in the energy industry have employed standardized weather contracts trading on organized exchanges since 1999 and the interest in non-standardized contracts for specialized weather related risks is growing at an increasing rate. The purpose of this paper is to examine the potential use of weather derivatives to hedge against temperature related risks in Canadian ice wine production. Specifically we examine historical data for the Niagara region of the province of Ontario, Canada, the largest icewine producing region of the world, to determine an appropriate...

Pressures and Preferences Affecting Willingness to Apply Beef Manure on Crops in the Colorado High Plains
Provedor de dados: 31
Autores: Hoag,   Dana L.; Lacy,   Michael G.; Davis,   Jessica.
Little is known about producers' willingness to use manure. Past studies have focused on substitutability for fertilizers. We surveyed crop producers in a cattle-dense region of the Colorado Plains about whether and why they apply manure, focusing on how pressures (like owning cattle) or preferences (pro and con) affect their adoption. Using logistic regression, findings show that pressure and preference (PS/PF) significantly affect adoption. A producer with high PS/PF was 10 times more likely to use manure than one with low PS/PF. Policy and decision makers can use such findings to inform education and policy aimed at increasing the land application of manure.

Beyond semi-dwarf wheat yield increases: impacts on the Australian wheat industry of on-going spillovers from the International Maize and Wheat Improvement Center
Provedor de dados: 31
Autores: Brennan,   John P.
Wheat genetic materials developed from research at the International Maize and Wheat Improvement Center (CIMMYT) in Mexico for developing countries have provided spillover benefits to Australia. Varieties developed from those genetic materials have resulted in yield increases in Australia. While the initial impact came through the introduction of higher-yielding semi-dwarf wheat crops, those impacts have continued in the post-semidwarf period. CIMMYT’s success in developing countries has also reduced the world price for wheat. While the lower prices affect returns in Australia, the increased yields in Australia from the CIMMYT spillovers from both the semi-dwarfs and the postsemidwarf phases have provided benefits to Australia averaging A $30 million per...

CORPOICA and IFPRI implemented a research project in Ventaquemada, Colombia. The project’s goal was to asses the benefits of Integrated Pest Management (IPM) practices and the potential of Genetically Modified insect resistant (Bt) potatoes to manage damage caused by the Guatemalan Tuber Moth (Tecia solanivora Povolny). The Guatemalan Tuber Moth is particularly destructive because field spraying on the adult stage is ineffective and there exists damage specificity to the tubers. Excessive pesticide sprays have resulted in resistance to several insecticides. Insect resistant (Bt) potatoes has been shown an effective means to control other members of the Tuber Moth complex. Thus a Bt potato may play a role in managing Tecia in Colombia. This is an ex ante...

Agriculture’s impact on climate change is unambiguous although its role is multifaceted as it is a source of greenhouse gases but also a sink. It’s feasibility to mitigate climate change has raised interest, but thorough studies about the net benefits of the mitigation practices are needed. The aim of this paper is to analyse the social net benefits of barley cultivation on three different soil types in Finland (clay, silt and organic) by using an integrated economic and ecological model. We ask whether it would be privately or socially profitable to allocate some of barley cultivation permanently for alternative land uses or cultivation systems, when production costs, GHG emissions and surface water quality impacts are taken into account. We compare the...

A controversa presença da cana nos assentamentos rurais nos últimos anos exige uma cuidadosa reflexão sobre sua interferência no modo de vida dos assentados e na relação dos assentamentos com a dinâmica do desenvolvimento regional. A presença da cana nos assentamentos tem suscitado ao longo desse período conflitos internos, discussões, nada consensuais, sobre o passado/ presente/ futuro dessas experiências. A análise da parceria com as agroindústrias é atravessada, do nosso ponto de vista, pela noção de trama de tensões. Nos termos em que a parceria vem se concretizando, temos discutido a necessidade de desconstrução desse conceito calcado na matriz teórica de capital social e a importância de submeter ao crivo analítico as desigualdades constitutivas...

THE EXPECTED COST OF AN INCOME SUPPORT PROGRAM FOR PROCESSING ORANGES
Provedor de dados: 31
Autores: Weldon,   Richard N.; VanSickle,   John J.
The Florida citrus industry operates in a competitive global market. However, unlike program crops, producers in this industry do not benefit from direct income support under the new Farm Bill. There is concern about the impact of elimination of the orange juice tariff on the financial health of the Florida orange industry. The purpose of this paper is to examine the level of government expenditure that would be needed to provide income support to orange producers if the orange juice tariff were eliminated. For the span of the Bill direct payments to corn are estimated to total $25.1 billion. By comparison the direct expenditures incurred for an income support program for oranges would be substantially less. In the early years with the tariff in place the...

CHANGES IN TRANSPORTATION COSTS AND INTERREGIONAL COMPETITION IN THE U.S. APPLE INDUSTRY
Provedor de dados: 31
Autores: Dunn,   James W.; Garafola,   Lynn A.
An interregional competition model of the U.S. apple industry is constructed.  This model includes the consumer products of fresh apples, applesauce and apple juice.  The validation of the model showed that it did a good job of estimating consumer's quantity demanded and prices and a reasonable job of estimating utilization.  This model was used to study the effects of transportation cost changes on the industry in the short- and intermediate run.  The total production and consumption levels changed by moderate amounts with changing transport costs while the utilization of a region's crop was quite sensitive to such changes.

A BIOTIC CONTROL PERSPECTIVE ON NITRATE CONTAMINATION OF GROUNDWATER FROM AGRICULTURAL PRODUCTION
Provedor de dados: 31
Autores: Erickson,   Jon D.; Schlapfer,   Felix.
Agronomists consider the continuity and nutrient capturing properties of cover crops as important determinants of nutrient cycling in agricultural systems.  Managing for these biotic control functions can help limit nutrient loss and groundwater contamination between main crop harvests.  This simulation study highlights the potential role of cover crop management in a welfare economics framework.  The objective is to find the optimal combination of nutrient input to the main crop, the extent of off-season cover crops, and crop functional diversity to maximize the sum of benefits from agricultural production and groundwater protection.

A DYNAMIC INVESTMENT MODEL FOR TREE CROP AGRICULTURE
Provedor de dados: 31
Autores: Ajobo,   Owolabi.
The objective of this paper is to develop a dynamic model that may be useful in the analysis of investment in long term tree crop agriculture.  The model is based on linear programming as modified by fixed assets theory.  The starting point is the Heady-Loftsgard dynamic linear programming model restated in a stochastic form and imbedded in a decision theoretic construct to give a stochastic mixed integer programming model.  The paper goes into a discussion of problems associated with agricultural data collection in Nigeria-on the conviction that specific use of any model can only come after the data problem has been reasonably solved.

A stochastic, dynamic, and control-system econometric model of the wheat sector is developed to assess the effects of the Payment-in Kind program.  Empirical results the complex dynamics of the responses.  Reduced storage costs and deficiency payments for the U.S. government and increased income for wheat farmers are benefits from the PIK program in the short-run.  Increased direct government transfers from the public to support the program were required.  The long-run economic implications are not clearly desirable.  This is due primarily to the highly sensitive international wheat market.

Understanding Spatial Welfare Impacts of a Grain Ethanol Plant
Provedor de dados: 31
Autores: Van Wart,   Justin; Perrin,   Richard K.
A changing world of increasing complexity, fluctuating prices, high energy costs and limited data necessitate creative blending of economic theory and available empirical statistics to understand the welfare impacts in a specific market.  In this paper, a programming approach is used in tandem with spatial economic theory to understand the spatial welfare impacts of an ethanol plant established in an area with a beef feeding industry.  The study concludes that corn transportation costs are less significant in plant pricing strategy than originally identified by other studies.  Local ethanol plant competition is found to explain the lower-than-feed value pricing of ethanol byproducts at the plant.  In the study, average welfare effects are calculated for...

VARIETAL SALES AND QUALITY DIFFERENTIATION: THE CASE OF CERTIFIED SOYBEAN SEED IN THE SOUTHEASTERN U.S.
Provedor de dados: 31
Autores: Houston,   Jack E.; Jeong,   Kihong; Fletcher,   Stanley M.
Variation in annual soybean plantings contributes to uncertainty in supplies of and demand for soybean seed in the southeastern U.S. This study used an expenditure valuation approach in an hedonic analysis framework to estimate returns to soybean seed quality differentiation. Analysis of pooled cross-sectional and time series observations narrowed important quality characteristics to yield and disease resistance attributes. In general, unexpected environmental factors affect seed crops over time, and the demand for other performance attributes is less predictable than for expected yield attributes. The results also suggest that geographical location is not significantly related to sales of varietal soybean seed in the study area.

AN EXAMINATION OF PROFIT INEFFICIENCY OF RICE FARMERS IN NORTHERN GHANA
Provedor de dados: 31
Autores: Abdulai,   Awudu; Huffman,   Wallace E.
This paper employs a stochastic frontier model to examine profit inefficiency of rice farmers in the Northern Region of Ghana using farm-level survey data. The efficiency index, based on a half-normal distribution of the stochastic error term is related to farm and household characteristics. The empirical results show that farmers' human capital represented by the level of schooling contributes positively to production efficiency, suggesting that investment in farmers' education improves their allocative performance. Access to credit and greater specialization in rice production, are found to be positively related to production efficiency. A farmer's participation in nonfarm employment and being older, however, reduce production efficiency.  Farmers...

Increasing volumes and speed of agricultural trade and the opening of new markets for agricultural products create greater challenges to systems established to protect countries from invasive organisms that can be harmful to human and animal health, crops and natural environments. In reaction to the threat of exotic pests and diseases, the World Trade Organization recognises the right of country members to protect themselves from the risks posed by exotic pests and diseases through the application of Sanitary and Phytosanitary (SPS) measures. One possible response from exporting countries facing SPS trade barriers is to obtain pest-free area (PFA) certification. While large benefits can potentially be achieved from greater access to world markets through...

Pricing, Distribution and Adoption of Genetically Modified Seeds under Alternative Information Regimes
Provedor de dados: 31
Autores: Basu,   Arnab K.; Qaim,   Matin.
This paper considers genetically modified (GM) seed adoption decisions by farmers in a developing country under two alternative information regimes (with and without perfect information regarding production conditions) that allows the monopolist producer of GM seeds to either practice perfect discrimination or uniform pricing. Under each regime we analyze two scenarios: when the government can and cannot credibly commit to the announced form of welfare enhancing intervention in the domestic seed market. We show that the optimal policy under either information regime is to subsidize the price of conventional seeds. The optimal size of the conventional seed subsidy depends systematically, in turn, on the (i) marginal cost of GM and conventional seeds, (ii)...

A DESCRIPTIVE AND ECONOMETRIC ANALYSIS OF RELATIONSHIPS IN THE RICE SUBSECTOR OF BURKINA FASO
Provedor de dados: 31
Autores: Hebie,   Sekou.
As in almost all sub-Saharan African countries, agriculture plays an important role in the economic life of Burkina Faso. The World Bank's 1983 report indicates that agriculture's contribution to the country's Gross Domestic Product (GDP) was 41 percent in 1981 compared to 16 percent for the industrial sector.  In 1980, exports of agricultural products (basically cotton, groundnuts, and livestock) accounted for 89 percent of total export earnings.  The country is primarily agricultural, with nearly 90 percent of the population dependent on agriculture as a livelihood.  Yet it is well known today that Burkina Faso, going into its third decade as a sovereign nation, is still facing, like its Sahelian counterparts, one of the biggest challenges of economic...

INVESTMENT ANALYSIS OF ALTERNATIVE FRUIT TREE SPRAYERS IN MICHIGAN ORCHARDS
Provedor de dados: 31
Autores: Swinton,   Scott M.; Asuming-Brempong,   Samuel; van Ee,   Gary R.
Changing orchard sprayer technology and rising pesticide costs to fruit growers raise the need to analyze the profitability of alternative sprayer investments.  This study analyzes investments in four orchard sprayers for use in Michigan apple production: an air blast sprayer, a tower boom sprayer, a tower boom sprayer equipped with electronic sensors that activate spray nozzles when foliage is detected, and an air curtain sprayer that targets spray with a layer of forced air.  Assuming equal pest control efficacy, the study calculates the annualized net present cost per acre of owning and operating each sprayer for ten years using a baseline discount rate of 10 percent over 200 acres of semi-dwarf apple trees.   The analysis found the annualized net...

Autores: Boteon,   Margarete; Silva,   Rafaela Cristina Da; Deleo,   Joao Paulo Bernardes.
A tecnologia está mais acessível ao produtor. O valor de um computador hoje equivale a 1 tonelada de adubo (uréia). A medida que o custo da tecnologia caiu, os valores dos fatores de produção – fertilizantes e salários – subiram significamente. Assim, é vital o produtor encontrar formas de otimizar o uso de insumos e melhorar a produtividade da mão-de-obra no campo. A superação desse desafio pode ter apoio importante na tecnologia da informação. Pesquisa realizada com produtores de frutas e hortaliças observou que boa parte deles já tem acesso aos principais meios de comunicação. No entanto, o uso desses meios integrado ao sistema de produção, como controle de custos de produção e uso de ferramenta de agricultura de precisão, ainda é pequeno. A conclusão...

Livestock and water interactions in mixed crop-livestock farming systems of Sub-Saharan Africa: Interventions for improved productivity
Provedor de dados: 31
Autores: Descheemaeker,   Katrien; Amede,   Tilahun; Haileslassie,   Amare.
Focusing on mixed crop-livestock farming systems of sub-Saharan Africa, this review brings together the available knowledge in the various components of the livestock and water sectors. Through an analysis of livestock-water interactions, promising strategies and interventions to improve Livestock Water Productivity are proposed. In the biophysical domain, the numerous interventions relate to feed, water and animal management. These are interlinked with interventions in the socio-political-economic domain. The paper identifies critical research and development gaps in terms of methodologies for quantifying water productivity and integrating different scales, and also in terms of institutions and policies.

Welfare Impacts of Property Rights in the Seed Industry
Provedor de dados: 31
Autores: Lence,   Sergio H.; Hayes,   Dermot J.; McCunn,   Alan; Smith,   Stephen C.; Niebur,   Bill.
The paper examines the welfare impact of different intellectual property right (IPR) regimes in private sector seed research.  The model takes into account the period after expiration of IPR protection, and requires a simultaneous equilibrium in the markets for R&amp;D, seeds, and final product (grain).  Simulation results show that with the exception of R&amp;D productivity, the optimal level of IPR protection is remarkably insensitive to parameters of the model.  There is a range of IPR appropriability levels where the interests of consumers and producers (taken together) are complementary to the interests of R&amp;D firms, and another range of appropriability levels where the welfare of producers and consumers can be increased only at the expense of the...

Factors influencing adoption of agroforestry among smallholder farmers in Zambia
Provedor de dados: 31
Autores: Kabwe,   Gillian; Bigsby,   Hugh R.; Cullen,   Ross.
Agroforestry technologies have been extensively researched and introduced to smallholder farmers in Zambia for over two decades. Despite the research and extension effort over this period, not many farmers have adopted these technologies. The purpose of this paper is to determine why agroforestry technologies are not being taken up by examining factors that influence the adoption of agroforestry practices. Based on data obtained from 388 farming households, statistical analysis show an association between adoption of both improved fallows and biomass transfer technologies with knowledge of the technology, availability of seed, and having the appropriate skills. In addition some household characteristics are found to be linked to the incidence of adoption....

ADDITIVE VERSUS PROPORTIONAL PEST DAMAGE FUNCTIONS: WHY ECOLOGY MATTERS
Provedor de dados: 31
Autores: Mitchell,   Paul D.
Economic analyses of pests typically assume damage is either additively separable from pest free yield or proportional to it.  This paper describes the ecological assumptions required for additive and proportional damage functions to demonstrate that both specifications are reasonable.  Ecological research supports a proportional damage function for competitive pests such as weeds, while for insect pests the appropriate damage function depends on the level of pest free yield.  Theoretical analysis identifies differences between additive and proportional damage functions in terms of the impact of pest control on output variance and the concavity of output in the pest control input.

A DYNAMIC ANALYSIS OF THE IMPACT OF WATER QUALITY POLICIES ON IRRIGATION INVESTMENT AND CROP CHOICE DECISIONS
Provedor de dados: 31
Autores: Wu,   JunJie; Mapp,   Harry P., Jr.; Bernardo,   Daniel J.
A dynamic model is developed to analyze farmers' irrigation investment and crop choice decisions under alternative water quality protection policies.  The model is applied to an empirical example in the Oklahoma High Plains.  The choices of crops and irrigation systems and the resulting levels of irrigation, income, and nitrogen runoff and percolation are simulated over a ten-year period.  An effluent tax on nitrogen runoff and percolation is shown to be effective in reducing nitrate pollution.  The efficacy of cost sharing in adopting modern irrigation technologies and restrictions on irrigation water use depends on soil type.  A tax on nitrogen use is shown to be the least effective policy.

Pathways out of poverty through secondary crops and private sector processing as well as institutional arrangements in Viet Nam
Provedor de dados: 31
Autores: Anh,   Dao The; Thinh,   Le Duc; Binh,   Vu Trong; Huan,   Dao Duc.
In Viet Nam, the diversification of CGPRT crops is the main thrust of poverty alleviation in remote and mountainous areas with new opportunities in the market. However, the sustainable development of these commodity chains is in question due to the lack of integrated policy for value chain development and assuring the participation of the poor in the value chains. Two case studies of cassava and maize commodity chains respectively in Yen Bai and Son La provinces suggest ways to encompass these challenges of diversification.

Effects of Socio-Institutional and Emotional Factors of Japanese Farmland Rental Transactions
Provedor de dados: 31
Autores: Kunimitsu,   Yoji.
Farmland reallocation between farmers through rental transactions is critical for improving Japanese rice productivity.  This study examined effects of socio-institutional and emotional factors as well as economic factors on rental transactions.  A stochastic choice model was applied to contingent valuation data by considering regional heteroscedasticity.  Empirical results showed (1) existence of economic inefficiencies, 3% loss of economic surplus due to socio-institutional restriction, which is probably reflected in transaction costs; (2) a 15% reduction in surplus due to emotional reluctance of farmers; and (3) strong influences of rice price, wages, and geographical location on the rental rate and agreement level.

The farm level economic impacts of the Farm Security and Rural Investment Act of 2002 on representative crop and livestock operations are projected in this report. The analysis was conducted over the 2001-2008 planning horizon using FLIPSIM, AFPC’s whole farm simulation model. Data to simulate farming and ranching operations in the nation’s major production regions came from two sources: - Producer panel cooperation to develop economic information to describe and simulate representative crop, livestock, and dairy farms. - Projected prices, policy variables, and input inflation rates from the Food and Agricultural Policy Research Institute (FAPRI) January 2004 Baseline. The primary objective of the analysis is to determine the farms’ economic viability by...

Assessment of Kenya's Domestic Horticultural Production and Marketing Systems and Lessons for the Future
Provedor de dados: 31
Autores: Tschirley,   David L.; Ayieko,   Miltone W.
After reviewing trends in the production and marketing of fresh produce for the domestic market in Kenya since 1997, this paper presents detailed information on the structure of the flow of this produce from rural areas to wholesale markets in Nairobi and from those wholesale markets to assorted retail markets. Market shares are estimated by product for geographic areas supplying Nairobi, and for each important wholesale and retail market in the city. It is found that horticultural production for the domestic market is keeping up with rural population growth but not with the much faster urban population growth. The urban wholesaling and retailing system has decentralized dramatically and with little planning over the past two decades in response to lack of...

Weather risk and machinery costs – A Monte Carlo simulation for the wheat harvest
Provedor de dados: 31
Autores: Lips,   Markus; Bolli,   Simon.
In eastern Switzerland there is a substantial weather risk during the wheat harvest. Increasing the number of available combine harvesters reduces harvest losses due to bad weather conditions, whilst increasing machinery costs. Simulating weather risk, we analyse harvest losses and machinery costs. In doing so, we apply both a deterministic and a stochastic approach – the latter by means of a Monte Carlo simulation. The costs per hectare of wheat are higher in the stochastic approach, because bad weather conditions lead to high costs. There is no difference between the two approaches in terms of minimum costs, which in both cases are achieved by a density of 20 harvesters per 1000 hectares. Calculation results are lower than the actual density, which is...

Constructing Farm Level Yield Densities from Aggregated Data: Analysis and Comparison of Approaches
Provedor de dados: 31
Autores: Cooper,   Joseph C.; Langemeier,   Michael R.; Schnitkey,   Gary D.; Zulauf,   Carl R.
Yield variability can be significantly higher at the farm level than at more aggregated levels, including the county. However, due to a dearth of available farm level data, much stochastic analysis involving farm yields utilizes more aggregated yield data as a proxy for the farm level.  We empirically evaluate farm-level variability using longitudinal farm level data sets available from the Kansas Farm Management Association and the Illinois Farm Business and Farm Management Association.  For corn, soybeans, and wheat, we compare the farm level yield variability obtained from this data to that inferred from Federal crop insurance premiums.  The farm management data exhibit lower yield variability than are implied by the crop insurance premiums.

Effects of Marketing Loans on U.S. Dry Peas and Lentils:  Supply Response and World Trade
Provedor de dados: 31
Autores: Lin,   William W.; Lucier,   Gary.
The 2002 Farm Act required USDA to implement marketing loans for the 2002-07 crops of dry peas, lentils, and small chickpeas. This provision led to expanded acreage for dry peas and lentils, crops analyzed in this study. The analysis found that marketing loans played a role in expansion for dry peas in 2003-05 and for lentils in 2003. For dry peas and lentils, marketing loans contributed to acreage expansion in North Dakota and Montana. Simulation model results suggest that marketing loans had negligible impacts on world prices for dry peas and lentils in 2003-05. Impacts on U.S. exports were minor, increasing by about 2 percent in 2003.

The Effects of Energy Price Increases on Dutch Horticulture
Provedor de dados: 31
Autores: Bunte,   Frank H.J.; van Galen,   Michiel A.
This paper elaborates on the effects of a rise in energy costs for Dutch glasshouse horticultural producers. The effects on production, bilateral trade and consumption in 25 European countries plus Morocco, Turkey and the Rest of the World, are estimated using a version of the HORTUS partial equilibrium supply and demand model. This model includes 11 sorts of fruit and vegetables, and two categories of ornamental plants and flowers. As energy, especially natural gas, is a major intermediate input in Dutch glasshouse horticulture, it has potentially large impacts on producers and trade. The results indicate that a 10 percent increase in energy prices could cause significant shifts in production and trade flows, as well as some changes in consumption...

How much can be gained by optimizing nutrient abetment spatially – Cost – efficiency comparison of non – point arable loads from different Finnish watersheds
Provedor de dados: 31
Autores: Helin,   Janne; Tattari,   Sirkka.
Targeting has become the buzz word in the national agri-environmental policy reform in Finland. It is generally accepted that more environmental benefits could be reaped by implementing environmental protection measures where they have the biggest positive impact. However, considering one of the main environmental problems in Finland resulting from agriculture, eutrophication, the identification of first-best policy or even the biggest contributors among the diffuse nutrient sources remains as a considerable challenge. The model developed in this study aims to demonstrate how the agricultural nutrient load potential can be calculated in a way which supports the identifying of cost-efficient abatement policies. We use metamodeling of dynamic nutrient load...

Best Management Practices to Enhance Water Quality: Who is Adopting Them?
Provedor de dados: 31
Autores: Ghazalian,   Pascal L.; Larue,   Bruno; West,   Gale E.
This study investigates the determinants affecting producers’ adoption of some Best Management Practices (BMPs). Priors about the signs of certain variables are explicitly accounted for by testing for inequality restrictions through importance sampling. Education, gender, age, and on-farm residence are found to have significant effects on the adoption of some BMPs. Farms with larger animal production are more apt to implement manure management practices, crop rotation, and riparian buffer strips. Also, farms with larger cultivated acres are more inclined to implement herbicide control practices, crop rotation, and riparian buffer strips. Belonging to an agro-environment club has a positive impact for most BMPs.

Autores: Yunez-Naude,   Antonio; Juarez-Torres,   Miriam; Barceinas-Paredes,   Fernando.
Using a stochastic production frontier model and data for 2002 from a representative sample of Mexican rural households, in this paper we first study empirically whether or not small and medium farmers produce corn efficiently. The results show that corn production is inefficient, nation-wide and for both commercial and subsistence farmers. Our findings also show that this is even more so for subsistence producers and for the Center and the South-southeast regions of rural Mexico. In addition, we find that subsistence farmers use less prod uctive inputs (seeds and agrochemicals) with respect to commercial farmers. Based on these results, we then apply a regression model to inquire about the factors explaining inefficiency. We get that farmers facing...

Measuring the Contribution of Genetic Characteristics as an Indicator of Innovation: The Case of Corn in the USA, 1990-2009
Provedor de dados: 31
Autores: Nolan,   Elizabeth; Santos,   Paulo.
Intellectual Property Rights (IPR) regimes for plant breeding are generally justified on the basis that they encourage innovation. Introduction of IPR regimes for plant varieties in the United States has led to increased concentration, but it is less clear whether IPRs have promoted useful innovation, as measured by productivity of available corn hybrids. There are difficulties in finding a satisfactory measure of innovation in plant breeding, and in this paper we propose a procedure. Results from the annual corn hybrid trials conducted by 11 US universities over the 20 years from 1990 to 2009, at 365 separate locations in the 11 states, have been collated. This set of unbalanced panel data for grain corn hybrid trials has been used in a fixed effects...

Autores: Stair,   Christina Welch; Quan,   Peter; Martin,   Marshall A.
Economic questionnaires were administered in 1997 and 1998 to farmers in the Indiana/Illinois, Kansas, and Iowa sites involved in the Areawide Pest Management (AWPM) program for the control of corn rootworms.  These questionnaires provided information regarding variable and fixed costs of production for fields located within the management site and also the companion acreage.  The economic analysis indicated that yields, variable costs per acre, and machinery costs per acre were not statistically different within a site across the inner core, outer ring, and companion acreage, with relatively few exceptions.  This gives a solid baseline for a Net Present Value comparison between the soil insecticide and AWPM methods for control of corn rootworms, since...

A cultura cafeeira foi e continua sendo de primordial importância para a economia brasileira. Além de importante fonte de renda para a economia brasileira, o café tem destacada participação nas receitas cambiais, na transferência de renda entre setores e na formação de capital no setor agrícola nacional. Outro fator que privilegia o Brasil na produção cafeeira é o fato de sua produção ser em larga escala e diversificada, ao contrário da maioria dos países produtores que se especializam na produção de uma única espécie. A possibilidade de flutuações cíclicas nos preços e nas quantidades produzidas e/ou exportadas constitui sério problema para esse setor. Essa constatação motivou o presente estudo que utilizou basicamente dois métodos de análise para a...

Sensory Evaluation and Consumers’ Willingness to Pay for Quality Protein Maize (QPM) using Experimental Auctions in Rural Tanzania
Provedor de dados: 31
Autores: Kiria,   Christine G.; Vermeulen,   Hester; De Groote,   Hugo.
The purpose of this study was to evaluate the sensory characteristics and consumer acceptability of quality protein maize (QPM) in rural Tanzania. Due to the malnutrition problem facing consumers in developing countries, QPM which has almost double the amount of tryptophan and lysine, has been identified as a possible solution to this problem. To know whether consumers will accept QPM, it is vital that its sensory attributes and consumer acceptance tests are carried out. Sensory characteristics were determined using home use testing and central location methods by use of stiff porridge.

SEQUENTIAL STOCHASTIC PRODUCTION DECISIONS FOR A PERENNIAL CROP:  THE YIELD/QUALITY TRADEOFF FOR ALFALFA HAY
Provedor de dados: 31
Autores: Blank,   Steven C.; Orloff,   Steve B.; Putnam,   Daniel H.
The "optimal cutting schedule" for alfalfa hay is described as a function of the trade-off between rising yield and falling quality of alfalfa over time and the local market prices being offered for different qualities of hay during the harvest season.  Field test results quantify the yield/quality tradeoff for a California case study.  A general decision rule is then derived to assist growers in making cutting decisions during a season.  Finally, the optimal cutting schedule is shown to be the sum of sequential decisions for cuttings throughout the harvest season, with no schedule being best a priori.

Under the December 2006 Baseline, 25 of the 65 crop farms are considered in good liquidity condition (less than a 25 percent chance of negative ending cash in 2011). Five crop farms have between a 25 percent and a 50 percent likelihood of negative ending cash. The remaining 35 crop farms have greater than a 50 percent chance of negative ending cash. Additionally, 33 of the 65 crop farms are considered in good equity position (less than a 25 percent chance of decreasing real net worth during the study period). Eight crop farms have between a 25 percent and 50 percent likelihood of losing real net worth, and 24 crop farms have greater than a 50 percent probability of decreasing real net worth.

THE CROWDING OUT EFFECTS OF THE 2002 FARM BILL ON HEDGING: EVIDENCE FROM PACIFIC NORTHWEST GRAIN FARMS
Provedor de dados: 31
Autores: Wang,   H. Holly; Makus,   Larry D.; Chen,   Xiaomei.
The 2002 Food Security and Rural Investment (FSRI) Act introduced a price protection program called Counter Cyclical Payments (CCP) to major grain producers in the US.  The CCP program is an addition to the Loan Deficiency Payment (LDP) and Direct Payment (DP) programs from the previous 1996 Federal Agriculture Improvement and Reform (FAIR) Act.  At the same time, US federally subsidized crop revenue insurance programs also protect farmers from market and production risks.  These government policy programs may crowd out the traditional price risk management role of hedging in commodity futures markets.

Factors Contributing to Zambia’s 2010 Maize Bumper Harvest
Provedor de dados: 31
Autores: Burke,   William J.; Jayne,   Thomas S.; Chapoto,   Antony.
Key Points • Zambia’s maize crop grew by 48% between the 2009 and 2010 harvests, leading to the largest crop recorded in recent history. • Yield growth accounted for 59% of the maize production growth between 2009 and 2010. Expansion of area planted to maize explains an additional 23%, while the remaining 18% can be attributed to a rise in the ratio of harvested to planted land. • Favourable weather conditions contributed 47% of the maize yield growth between 2009 and 2010, whilst, 25% came from increased fertilizer use from both the private and public sectors, and 23% from area expansion. The remaining 5% can be attributed to hybrid seed use and improved management. • Due to favorable weather conditions in both 2008/09 and 2009/10 growing seasons, maize...

Weed Management: A Review of Applied Economics Research in Australia
Provedor de dados: 31
Autores: Pannell,   David J.
Australian research into the economics of privately and publicly funded weed control is reviewed. Of the published studies that consider farm-level problems, most have been simplistic. Complexities which affect a farmer's optimal control strategies for crop and pasture weeds are outlined. The determination of herbicide rates on an economic basis is proposed as an area for further work. The traditional economic threshold concept is not suitable for this purpose. Studies of the economics of public weed control programs are slightly more common than farm-level studies in the literature, although work on public weed problems has focussed on just a few weed species. Future directions for weed economics research are suggested.

This article presents an alternative approach to the specification of systems of crop acreage responses. Derived demands for acreages of individual crops are specified as conditional on total crop acreage, and related separability and dynamic specifications help to reduce the effects of multicollinearity in the system. A simple econometric model of crop acreage demands for Western Canada illustrates the methodology.

Actuarial Impacts of Loss Cost Ratio Ratemaking in U.S. Crop Insurance Programs
Provedor de dados: 31
Autores: Woodard,   Joshua D.; Sherrick,   Bruce J.; Schnitkey,   Gary D.
This study examines the actuarial implications of the loss cost ratio (LCR) ratemaking methodology employed by the Risk Management Agency as a component of base rates for U.S. crop insurance programs, and identifies specific conditions required for the LCR methodology to result in unbiased rates when liabilities trend. Specifically, constant relative yield risk resulting in growing absolute variance through time and other restrictive requirements are required for the LCR to result in unbiased rates. These requirements are tested against a large farm-level data set for Illinois corn. Our findings indicate that the conditions required for appropriate use of the LCR methodology are violated for this high premium volume market, resulting in large implied rate...

A closer look at the role of the fruit and vegetable planting restriction provision on land use in the United States
Provedor de dados: 31
Autores: Lei,   Lei; Rickard,   Bradley J.; Balagtas,   Joseph Valdes; Krissoff,   Barry.
Current U.S. farm programs make payments to farmers based in part on historical base acres planted in particular program crops such as corn, soybeans, cotton, wheat and soybeans. Eligibility for payments includes regulations on the crops allowed to be grown on base acres, and there are restrictions on planting horticultural crops on such base acres. The fruits and planting restriction on base acres has potentially influenced the number of acres planted to fruits and vegetables over the past two decades. This research carefully examines the effects of planting restrictions applied to vegetables and program crops, using county-level data in the United States in 1982, 1987, 1992 and 1997. The paper employs the difference-indifference (DiD) approach to...

Smallholders' Cost Efficiency in Mozambique: Implications for Improved Maize Seed Adoption
Provedor de dados: 31
Autores: Zavale,   Helder; Mabaya,   Edward T.; Christy,   Ralph D.
Maize is an important staple in Mozambique. It is also a dominant crop produced by smallholder farmers. However, the actual maize yields, currently estimated at 1.4 tons/ha, fall short of potential yields of 5-6.5 tons/ha. With population growth rate increasingly exceeding agricultural (and maize) productivity growth rate, the government of Mozambique faces a serious problem of food insecurity and poverty alleviation. This study examines cost inefficiency among smallholder maize farmers in Mozambique, and the impact of improved maize seed adoption on cost efficiency. A Translog functional form is used to estimate the frontier cost function. A cost-inefficiency function is used to examine the factors that determine cost inefficiency among farmers....

Trade-distorting SPS and TBT regulations in the EU? A qualitative assessment from the market for live plants and cut flowers.
Provedor de dados: 31
Autores: Drogue,   Sophie; Gozlan,   Estelle.
Using specific estimation of ad-valorem equivalents, the paper compares sectors where observed trade flows are significantly lower than predicted flows, with sectors where a SPS/TBT measure is notified in the TRAINS database. Only three sectors are found where a significant negative coefficient matches a notified regulation. Focusing on the market for live plants and cut flowers, the paper provides a description of existing EU import requirements and discusses recent trends in relevant private standards and certification schemes. The trade-restrictiveness of EU and private standards is then assessed based on the results of a survey conducted among exporters of flowers in developing countries.

Energy Crop Production Costs and Breakeven Prices Under Minnesota Conditions
Provedor de dados: 31
Autores: Lazarus,   William F.
Production costs and breakeven prices were calculated for four energy crops plus corn stover.  The energy crop breakeven prices were calculated under two different scenarios regarding land costs and the opportunity costs of not utilizing the land for some other competing land use.  One scenario is that the competing land use is pasture.  The other is that the energy crops would compete with grain crops on more expensive land, and would need to provide a return over land costs equal to returns on the grain crops.   Corn stover would be the cheapest of the energy biomass sources considered, at $50/ton to cover the additional machinery costs to shred, rake, bale, and transport 25 miles to a processing plant.  Aside from stover, a grassland crop under high...

Watching Corn Grow: A Hedonic Study of the Iowa Landscape
Provedor de dados: 31
Autores: Secchi,   Silvia.
Landscape amenities can be scarce in places with large areas of open space. Intensely farmed areas with high levels of monocropping and livestock production are akin to developed open space areas and do not provide many services in terms of landscape amenities. Open space in the form of farmland is plentiful, but parks and their services are in short supply. This issue is of particular importance for public policy because it is closely linked to the impact of externalities caused by agricultural activities and to the indirect effects of land use dynamics. This study looks at the impact of landscape amenities on rural residential property values in five counties in North Central Iowa using a hedonic pricing model based on geographic information systems.

CERTIFICATION AND SUPPLY RESPONSE IN THE ORGANIC LETTUCE MARKET
Provedor de dados: 31
Autores: Lohr,   Luanne; Park,   Timothy A.
The impact of supply relationships and certification programs on the organic lettuce market is examined using an integrated partial adjustment and asymmetric supply response model. Costs associated with organic certification, production, and marketing have not restricted producers’' abilities to respond to price signals. Organic growers allocate output between certified and noncertified markets in response to changing price premiums. Estimates of short-run supply elasticities indicate that organic lettuce growers are more responsive to price changes than producers of nonorganic lettuce. Long-run elasticity has increased since 1988, a change that coincides with the market entry of larger producers.

Accounting for agronomic rotations in crop production: A theoretical investigation and an empirical modeling framework
Provedor de dados: 31
Autores: Carpentier,   Alain; Gohin,   Alexandre; Letort,   Elodie.
As far as crop acreage choices are concerned, a consensus seems to exist among agricultural scientists and extension agents: crop rotation effects and the related constraints are major determinants of farmers’ crop choices. Crop rotation effects are inherently dynamic. They are generally ignored in multicrop models with land as an allocable input found in the literature since most of these models are developed within a static framework. The aim of this paper is twofold (i) to propose a new approach and tools for investigating dynamic crop acreage choices accounting for crop rotation benefits and constraints and (ii) to illustrate the impacts of crop rotation effects and constraints on farmers’ acreage choices through simulation examples. The models...

How Far Can Poultry Litter Go? A New Technology for Litter Transport
Provedor de dados: 31
Autores: Carreira,   Rita I.; Young,   Kenneth B.; Goodwin,   Harold L., Jr.; Wailes,   Eric J.
Exporting northwest Arkansas excess turkey and broiler litter to partially fertilize nutrient-deficient cropland in eastern Arkansas can be more cost effective than to supply all crop nutrients with chemical fertilizer only, given current high fertilizer prices.  Cost savings are greater if litter is baled in ultraviolet resistant plastic and transported via truck, since backhaul opportunities reduce truck rates, or alternatively, if raw litter is shipped via a truck-barge combination.  Rice is the crop that allows for greater savings according to a mathematical programming model implemented in General Algebraic Modeling System (GAMS).

INVENTORY AND TRANSFORMATION RISKS IN SOYBEAN PROCESSING
Provedor de dados: 31
Autores: Dahlgran,   Roger A.
This study examines strategies for hedging processing operations generally and uses soybean processing as a specific example. The approach assumes a mean-variance utility function but because of the focus on hedging, the analysis concentrates on risk minimization with risk defined as the variance of the processing margin from its currently expected level. We find that risk so defined contains three components. These are (1) the risk of input/output cash price misalignment at the time of transactions, (2) the risk resulting from the firm's inability to utilize inputs and produce outputs in proportion to the mix that minimizes risk in cash market transactions, and (3) the risk of price change during the time between the purchase of inputs and the sale of...

Readdressing the Fertilizer Problem
Provedor de dados: 31
Autores: Paulson,   Nicholas D.; Babcock,   Bruce A.
The production literature has shown that inputs such as fertilizer can be defined as risk-increasing. However, farmers also consistently overapply nitrogen. A model of optimal input use under uncertainty is used to address this paradox. Using experimental data, a stochastic production relationship between yield and soil nitrate is estimated. Numerical results show that input uncertainty may cause farmers to overapply nitrogen. Survey data suggest that farmers are risk averse, but prefer small chances of high yields compared to small chances of crop failures when expected yields are equivalent. Furthermore, yield risk and yield variability are not equivalent.

Estimating the Potential Value of Variable Rate Nitrogen Applications: A Comparison of Spatial Econometric and Geostatistical Models
Provedor de dados: 31
Autores: Hurley,   Terrance M.; Oishi,   Kikuo; Malzer,   Gary L.
Site-specific crop response functions (SSCRFs) are useful for estimating the value of variable rate nitrogen applications (VRA), but appropriate statistical models are necessary. Problems estimating SSCRFs using experimental field data include region, spatial, treatment, and strip dependent heteroskedasticity and correlation. We develop a spatial autoregressive error (SARE) model for dealing with these problems and compare results with previous analysis based on a geostatistical (GEO) model. VRA value estimates for the two models differ notably for 1995 data from Southern Minnesota. Furthermore, findings show that the results of a comparison of model performance are location specific.

IN SITU CONSERVATION OF CROP GENETIC RESOURCES IN THE MEXICAN MILPA SYSTEM
Provedor de dados: 31
Autores: Van Dusen,   M. Eric.
This dissertation focuses on the theoretical modeling and empirical testing of household motivations for the in situ conservation of crop genetic resources (CGR). An original household survey is used to test whether the household diversity outcomes are different for the cropping system as a whole, for the principal crop, maize, or for the secondary crops, beans and squash.  Agro-ecological characteristics and market characteristics are found to significantly affect the levels of diversity maintained by households.     A review of the economic literature relevant to modeling in situ conservation is presented.  A theoretical model is developed in which a household's decision to plant a milpa variety is linked to household, agro-ecological, and market...

TECHNICAL EFFICIENCY OF CHINESE GRAIN PRODUCTION: A STOCHASTIC PRODUCTION FRONTIER APPROACH
Provedor de dados: 31
Autores: Chen,   Adam Zhuo; Huffman,   Wallace E.; Rozelle,   Scott.
This article examines technical efficiency of the Chinese grain sector using the framework of stochastic production frontier. The results reveal that: the marginal products of labor and fertilizer are much smaller than that of land; human capital and farm-level specialization have positive effect on efficiency, land fragmentation is detrimental to efficiency, and elder farmers are as efficient as younger farmers. We also examine the effects of size, mechanization and geographic location. Simulation results show that significant output gains can be obtained by eliminating land fragmentation, improving rural education and promoting specialization and mechanization.

PESTICIDE TAX, CROPPING PATTERNS, AND WATER QUALITY IN SOUTH CENTRAL TEXAS
Provedor de dados: 31
Autores: Shumway,   C. Richard; Chesser,   Rayanne R.
The impact of an ad valorem pesticide tax on cropping patterns and pesticide use was examined in the South Central Texas Crop Reporting District.  Output supply equations were econometrically estimated and used in the simulation.  A 25 percent tax on pesticide was estimated to have major impacts on cropping patterns and on pesticide use.  Assuming other input and output prices were unaffected, the supply of one important crop would fall by more than half.  Demand for some of the highly soluble and persistent pesticides, which present the greatest threat to groundwater quality, would also decrease substantially (some as much as 50 percent).

Environmental Indices for the Chinese Grain Sector
Provedor de dados: 31
Autores: Chen,   Ming; Karp,   Larry S.
Increased population pressure and political decisions have led to more intensive agricultural practices in China. As in other regions of the world, these practices can damage natural capital We use the Kalman filter and Chinese panel data to estimate an index of environmental productivity (natural capital), together with the parameters of environmental dynamics and the production function. These estimates show that intensive practices are likely to have had persistent, substantial, and statistically significant negative effects on productivity. Ignoring these effects can cause substantial misallocation of resources. The results illustrate the possibility of estimating sectoral environmental indices using data commonly available.

Autores: Soliman,   Ibrahim; Fabiosa,   Jacinto F.; Gaber Amer,   Mohamed; Kandil,   Siham.
From 1986 to 2007 Egypt’s agricultural policy transitioned from a tightly controlled to a more liberalized regime. This study examines the impact of this change on the performance of the wheat (imported grain) and rice (exported grain) sectors.   In terms of profitability, we found that the cost of production increased substantially in both grains, driven primarily by the rise in land rent and labor wage. But the wheat and rice sectors’ profitability did not suffer significantly, as advances in new seed technologies and adoption of better farm practices including farm mechanization increased yield and compensated for the higher cost.    Considering market efficiency, we found that over the study period the farmer’s share of the consumer’s expenditure...

Az öntözés egyik alapvető célja, hogy javítsa az egyre növekvő népesség élel-miszerrel való ellátását. A világon jelenleg a szántóterület 17%-át öntözik, vi-szont ez a felület adja az évenként betakarítható össztermés valamivel több mint 40%-át. Hazánkban a vízjogi engedéllyel rendelkező öntözésre berendezett terü-letünk 210 ezer hektár, ami a szántóterület közel 5%-a, de a ténylegesen öntözött terület évjárattól függően ennek kb. a fele. Az Európai Unióban átlagosan a szántóterület 13,5%-a tekinthető öntözöttnek. Az elkövetkező évek alapvető fejlesztési feladata a már meglévő öntözőrend-szerek felújítása és bővítése. A szántóföldi növények közül a kukorica, a napra-forgó, a cukorrépa és a burgonya öntözése indokolt. Az öntözött területek ará-nyának...

This report evaluates the U.S. and world sugar markets for 2006-2016 using the Global Sugar Policy Simulation Model. This analysis is based on assumptions about general economic conditions, agricultural policies, population growth, weather conditions, and technological changes. Both the U.S. and world sugar economies are predicted to remain profitable over the next ten years mainly because higher world oil prices have increased the conversion of sugar into ethanol by Brazil, while other exporting countries have increased their production in response to those higher prices. Brazil is the largest exporter of sugar, and it is expected that the rate of increase in Brazilian sugar exports may be reduced due to high oil prices. World demand for sugar is expected...

Surveys on consumer acceptance of GM foods revealed differences in knowledge, risk perception and acceptance of GM foods in Japan, Norway, Spain, Taiwan and the United States. There were opponents and proponents of GM foods. However, even in the United States, one of the most supportive countries, consumers were willing to pay substantial premiums to avoid GM alternatives. While genetic engineering holds great potential to enhance yield and productivity for many crops, especially those widely cultivated in the developing world, there have been little, if any tangible benefits to the consumer from the first wave of GM crops. Partially due to this lack of consumer benefits, there has been consumer resistance to GM foods in many parts of the world. It would...

Optimal Grazing Termination Date for Dual-Purpose Winter Wheat Production
Provedor de dados: 31
Autores: Taylor,   Karen W.; Epplin,   Francis M.; Brorsen,   B. Wade; Fieser,   Brian G.; Horn,   Gerald W.
Dual-purpose winter wheat (fall-winter forage plus grain) production is an important economic enterprise in the southern Great Plains. Grazing termination to enable grain production is a critical decision. The objective is to determine the optimal grazing termination date for dual-purpose wheat. The value of knowing the occurrence of first hollow stem (FHS), a wheat growth threshold for grazing termination, is also determined. Results indicate that for most price situations grazing should be terminated at or before FHS. Marginal wheat returns from extended grazing were negative and the value of FHS information ranges from $1.50 to $10 per acre.

It has been a long time since we have seen a cost of production study for horticultural crops, notably processing vegetable crops, in New York State; however, research in this arena is completed in many other states and continues to offer useful information to industry stakeholders. This type of information is especially important in the processing vegetable sector in New York State as it has seen substantial acreage decreases in recent years. Here we develop a survey to collect data from processing vegetable growers in New York State and use it to calculate costs and net returns of producing snap beans and green peas. Our results indicate that the average cost of producing snap beans in New York State is $568 per acre and is $563 per acre for green peas;...

Modeling Texas Dryland Cotton Yields, With Application to Crop Insurance Actuarial Rating
Provedor de dados: 31
Autores: Chen,   Shu-Ling; Miranda,   Mario J.
Texas dryland upland cotton yields have historically exhibited greater variation and more distributional irregularities than the yields of other crops, raising concerns that conventional parametric distribution models may generate biased or otherwise inaccurate crop insurance premium rate estimates. Here, we formulate and estimate regime-switching models for Texas dryland cotton yields in which the distribution of yield is conditioned on local drought conditions. Our results indicate that drought-conditioned regime-switching models provide a better fit to Texas county-level dryland cotton yields than conventional parametric distribution models. They do not, however, generate significantly different Group Risk Plan crop insurance premium rate estimates.

Environmental Benefits from Reduced Pesticide Use and Returns to Research: An Application to the U.S. Cotton Industry
Provedor de dados: 31
Autores: Sande,   Doris N.; Mullen,   Jeffrey D.; Matekole,   Augustus N.
Cotton production is one of the main pesticide use industries in the U.S. This intensive use has resulted in the disruption of naturally occurring biological control factors that regulate other insect pest populations and “the pesticide treadmill”. The result is resistance to insecticides, high control costs and unacceptable levels of chemical insecticides in the environment. Concerns about the environmental and human health effects from pesticide use thus need to be modeled in evaluation studies.

Previous climate information studies have used static models to estimate the benefits of using seasonal forecasts.  Technology adoption studies, on the other hand, have used dynamic models but have examined the benefits of adoption ex post.  The objective of this study is to examine ex ante the effects of climate forecast adoption on the international wheat market over time.  Two general sets of scenarios are analyzed.  The first set assumes all wheat-producers within a country or set of countries adopt the forecasts, while producers in the remaining country (ies) do not.  Next, producers adopt sequentially over time based on S-shaped adoption curves, whose rates vary by country.  Welfare implications are examined and compared in the different scenarios....

Existing literature suggests the influence of household wealth on farmer's technology adoption decisions. In 2007, this study was conducted to provide a clearer understanding of how differences in household wealth affect the way in which other variables influence adoption decisions. Using data from 369 households in Adama and Adami Tulu Jido Kombolcha districts of Ethiopia, the paper first stratified households into poorly and well-endowed categories based on wealth indices constructed using their productive assets by the principal components method. A double hurdle model was then specified and estimated for each wealth group to assess factors influencing the adoption and use intensity of improved varieties.

UNITED STATES AND CANADIAN AGRICULTURAL HERBICIDE COSTS: IMPACTS ON NORTH DAKOTA FARMERS
Provedor de dados: 31
Autores: Taylor,   Richard D.; Koo,   Won W.
Pesticides have become a major farm production cost over the past 25 years. There are price and label differences for agricultural herbicides between the United States and Canada. Trade names are different in some cases, label restrictions vary, and weights and measures are different. The reasons for the price differences are unclear. Whether they are due to increased costs in labeling requirements, different levels of competition and use, or market segmentation is not determined. The largest total impact of using lower priced Canadian herbicide is on HRSW, followed by durum and corn. The largest per acre impact is for canola, corn, and HRSW. Herbicides with the largest total impact are Puma, followed by Roundup and Fargo. Net farm income for large,...

Autores: Bangsund,   Dean A.; DeVuyst,   Eric A.; Leistritz,   F. Larry.
Switchgrass, a warm-season perennial grass, native to the region, has received considerable interest for its potential role as a dedicated feedstock for cellulosic-based bio-fuels.  This research examined the farm-gate price needed for switchgrass to provide per-acre net returns equal to those obtained from traditional crops in south central North Dakota.    Future production costs for switchgrass and net returns from traditional crops were estimated for three soil productivity classes and also were developed to reflect the historical revenue and cost patterns associated with producers who are typically more or less profitable (i.e., average net return per acre) than regional averages.  Prices were calculated using an annualized equivalent analysis of...

Prospects of Chinese Grain Supply and Demand in 2010: A Regionalized Multimarket Model Simulation and Policy Implication
Provedor de dados: 31
Autores: Lu,   Wencong C.; Kersten,   Lutz.
Based on China's Agricultural Regional Market Equilibrium Model (CARMEM), the paper projects the production and consumption of rice, wheat and maize in China toward 2010 at both national and regional level under two different scenarios. The results show that China can ensure a stable grain market development under more liberalized internal and external conditions. Transmission of the world market prices as projected by the World Bank (2003) to the Chinese domestic market would lead to a long-run recovery of the growth in grain production. Total production of paddy rice, wheat and maize is forecast to increase from 386 million tons in the base period 2002 to over 420 million tons in 2010. However, the rate of grain self-supply will be 91% due to higher...

Actual farm records were used to evaluate variation of crop yields for corn, wheat, and soybeans grown in Michigan.  The assumption of yields being normally distribute with independent and constant variance was tested for all farms, farms characterized by soil groupings, and individual farms of a selected soil group.  Sufficient evidence was not found to reject the assumption that yield variation is normally distributed with independent and constant variance when all farms were grouped together.  Grouping farms by soil potential showed strong support for yields being independent and normally distributed.  The assumption of constant variance had strong support for wheat, but was weak for corn.  Analysis of individual farms for a selected soil group,...

In recent years, plant breeders' rights (PBR) has become a controversial subj ect worldwide. This paper reports the results of a survey of the seed distribution industries in the nine member countries of the International Union for the Protection of New Varieties of Plants (UPOV) as well as the seed trade in the United States (U.S . ) and Canada. The general consensus of the UPOV members was that PBR had resulted in increased private investment in plant breeding and that there had been a shift toward more basic research in the public sector. The findings in the U.S. were similar except that there the changes were perceived to be more crop specific with less funding available for public sector research. In Canada, the major concern centered around the...

AN EVALUATION OF INTEGRATED PEST MANAGEMENT WITH HETEROGENEOUS PARTICIPATION
Provedor de dados: 31
Autores: Wetzstein,   Michael E.; Musser,   Wesley N.; Linder,   David K.; Douce,   G. Keith.
Principal component analysis in employed to develop indices that distinguish between participants and nonparticipants in Integrated Pest Management (IPM) programs.  Results of incorporating these indices into yield, net return, and production cost functions for cotton producers indicate that both yield and costs increase as the degree of producer participation in IPM increases.  Although these results are inconsistent with previous research, they are consistent with the theoretical relationship between IPM and conventional input usage.

A Dynamic Decision Model of Technology Adoption under Uncertainty: Case of Herbicide-Resistant Rice
Provedor de dados: 31
Autores: Annou,   Mamane Malam; Wailes,   Eric J.; Thomsen,   Michael R.
Herbicide-resistant (HR) rice technology is a potential tool for control of red rice in commercial rice production.  Using an ex ante mathematical programming framework, this research presents an empirical analysis of HR rice technology adoption under uncertainty.  The analysis accounts for stochastic germination of red rice and sheath blight to model a profit maximization problem of crop rotation among HR rice, regular rice, and soybeans.  The results demonstrate that risk attitudes and technology efficiency determine adoption rates and optimal rotation patterns.

Wealth, Living Standards and Perceptions in a Cotton Economy: Evidence from the Cotton Reform in Burkina Faso
Provedor de dados: 31
Autores: Kaminski,   Jonathan.
The cotton economy of Burkina Faso has been characterized by a changing rural environment for farmers since late nineties, which has come with the cotton reform and the resulting cotton boost. There have been slight improvements in living standards and rural households’ income while the subjective feeling of wealth has significantly increased. In this paper, I explore the channels through which the elements of the changing rural environment can bridge the wedge between subjective and objective measures of wealth. In addition to the basic determinants of subjective welfare that can be found in the happiness economics literature, namely absolute and relative income measures, health and social status (and expectations of future incomes), I investigate the...

Policies and politics: Challenges and opportunities for agricultural and resource economists
Provedor de dados: 31
Autores: Pannell,   David J.
This is a broad-ranging discussion of the role of economics and economists in the formation of government policies. The focus is on helping economists who wish to be influential in the policy process. The paper covers rationales for and against economist involvement in the policy process (market failure, government failure, economist failure), a range of theories that attempt to explain aspects of the policy process, and practical advice and insights based on the experiences of policy economists. Many challenges are highlighted, but some clear opportunities are apparent, particularly through explicit advocacy for the public interest.

Increasing Demand For Quality In World Cotton Markets: How Has Zambia Performed?
Provedor de dados: 31
Autores: Tschirley,   David L.; Kabwe,   Stephen.
1. Changes in spinning technology have increased the premium on high quality lint in the world market and increased the discount for lint contaminated with non-vegetative matter 2. The inherent characteristics of most African lint, plus the fact that it is hand-picked, should give it a substantial premium in the world market. However, because so much African lint is highly contaminated by world standards, much of it trades at a discount to Index A. 3. Zambia has been the outstanding success among a sample of nine SSA countries in improving quality; this achievement is directly attributable to the efforts of Dunavant and Cargill, made possible by company culture and by the concentrated structure of Zambia's industry 4.

Ranking New Zealand river values – a novel approach to managing the ‘chalk and cheese’ problem
Provedor de dados: 31
Autores: Hughey,   Kenneth F.D.
In New Zealand, regional councils have the task of sustainably managing rivers and their flows. In trying to achieve this task they face enormous challenges including the need to allocate flows amongst often highly disparate in- (e.g., angling, kayaking, native fish and birds) and out-of-river (e.g., irrigation and hydro energy) values/needs. To aid in this task these councils need to know which rivers or parts of rivers are relatively more or less important on national, regional and local bases, for particular values. This task becomes even more challenging given limited information availability for many values, and no overarching policy or decision framework. In this paper I report on a FRST-funded (and less than 1-year long) project which has addressed...

The Canadian Wheat Board in an Open Market: The Impact of Removing the Single-Desk Selling Powers
Provedor de dados: 31
Autores: Fulton,   Murray E.
Over the summer and early autumn of 2006, the Government of Canada  has indicated its desire to remove the single-desk selling powers of  the Canadian Wheat Board (CWB). The purpose of this paper is to  explore the impacts of this proposal. The main conclusion of the  paper is that it will be very difficult, if not impossible, for the  CWB to survive as an organization. Thus, contrary to what the recent  task force report by the federal government indicates, the most  likely impact of removing the single-desk selling powers is that the  CWB will cease to exist. The elimination of the CWB would transform  the Canadian grains industry, with the impact of this change felt in  virtually every part of the system. The changes that would accompany  the loss of...

INCORPORATION OF WITHIN-SEASON YIELD GROWTH INTO A MATHEMATICAL PROGRAMMING SUGARCANE HARVEST SCHEDULING MODEL
Provedor de dados: 31
Autores: Salassi,   Michael E.; Champagne,   Lonnie P.; Legendre,   Benjamin L.
This study focuses on the development of a optimal harvest scheduling mathematical programming model which incorporates within-season changes in perennial crop yields.  Daily crop yield prediction models are estimated econometrically for major commercially grown sugarcane cultivars.  This information is incorporated into a farm-level harvest scheduling linear programming model.  The harvest scheduling model solves for an optimal daily harvest schedule which maximizes whole farm net returns above harvesting costs.  Model results are compared for a commercial sugarcane farm in Louisiana.

GRAIN PRICE STABILITY AND FARMER DECISION MAKING IN CHINA
Provedor de dados: 31
Autores: Chen,   Jing; Rozelle,   Scott; Carter,   Colin A.
In this paper we find that real grain prices in China have displayed increased volatility in the past decade. This is true for rice, wheat, corn, and for most of provinces. Farmers in China are found to be risk averse because when they make acreage allocation decisions.  Given the widespread access to land in China, farmers mostly respond negatively in their sown area decisions towards price risk.  The large price variations from 1984-1995 may have contributed to the slowdown in agricultural output growth from 1984-1995.

Potential adjustments in U.S. commodity program for rice are evaluated in this paper using stochastic analysis in a global modeling framework. Corresponding threshold and loss-compensatory increases in target price and loan rates are determined with assumed outright and gradual elimination of direct payments. Results show that if direct payments (DP) are eliminated in 2012, a 23% increase in both the target price (TP) and loan rate (LR) triggers counter-cyclical payments (CCP) 80% of the time; and it will take an increase of 48% in TP and LR to generate CCP enough to compensate for the loss in total DP. If DP is gradually removed over 5 years, the trigger and compensatory increases in TP and LR are 41% and 46%, respectively. Furthermore, if DP is...

A study was conducted during 1994-1995 amongst policy makers, government officials, retailers and millers in Lesotho to review the maize marketing system and procedures for setting maize prices at producer, mill-gate and consumer levels. Set prices distort price signals which influence decisions to allocate and distribute resources to provide goods and services for markets. Lesotho is a net importer of maize grain, the major staple, implying that maize pricing and marketing policy affect food security. Results indicate flexible informal marketing channels, fixed formal marketing channels and declining real producer, mill-gate and consumer prices in recent years Falling real South African Maize Board export grain prices and evidence of subsidies to...

Este trabalho tem como objetivo analisar o impacto do crescimento do preço de etanol no preço do açúcar. Para tal análise utiliza-se a metodologia de vetores autorregressivos para identificar a relação de causalidade entre os preços do etanol e do açúcar. O crescimento do preço do etanol é resultado de um aumento da demanda internacional pela commodity devido a questões ambientais, econômicas e geopolíticas; e resultado também do crescimento do consumo interno de etanol com a introdução de veículos flex na frota brasileira. Com esse aumento da demanda por etanol, foi gerada uma competição com a produção de açúcar, reduzindo a disponibilidade dessa commodity. Como resultado, foi encontrada uma relação de bicausalidade entre os preços do etanol e do açúcar....

Investment in Cellulosic Biofuel Refineries: Do Renewable Identification Numbers Matter?
Provedor de dados: 31
Autores: Miao,   Ruiqing; Hennessy,   David A.; Babcock,   Bruce A.
A floor and trade policy in Renewable Identification Numbers (RINs) is the market mechanism by which U.S. biofuel consumption mandates are met. A conceptual model is developed to study the impact of RINs on stimulating investment in cellulosic biofuel refineries. In a two-period framework, we compare the first-period investment level (FIL) in three scenarios: (1) laissez-faire, (2) RINs under a nonwaivable mandate (NWM) policy, and (3) RINs under a waivable mandate (WM) policy. Results show that when firm-level marginal costs are constants, then RINs under WM policy do not stimulate FIL but they do increase the expected profit of more efficient investors. When firm-level marginal costs are not constants, however, RINs under WM policy stimulate FIL. RINs...

A Survey of Literature on Genetically Modified Crops: Economics, Ethics and Society
Provedor de dados: 31
Autores: White,   R. McKay; Veeman,   Michele M.
This paper reports on a review of literature in the form of academic papers and published research on ethical and consumer issues for GM crops in North America, with particular emphasis on GM wheat. The issues raised in these papers and the findings and arguments posed by the authors are outlined. A general conclusion that can be drawn from this overview is that public attitudes toward GM foods are diverse and sometimes quite strongly held. The strong negative views of GM food held by some appear to be mainly grounded in individuals’ ethical or moral values. Ethical and risk assessment issues have not been fully explored in the existing literature. There is a general consensus in the applied economics literature that GM crops result in economic benefits,...

This paper presents a quantitative analysis of the Chinese wheat and rice industries.  The specific purpose is to analyze government policies for wheat and rice, and their impacts on industry performance.  Dynamic relationships among prices, quantities and total GNP are investigated with a vector autoregression using Chinese data. Government intervention in domestic commodity markets is quite common in China.  The Chinese government is not only heavily involved in production, but also in marketing and distribution of most commodities, especially agricultural products.  Production planning and collection rationing are used to reduce the need for food imports.  Grain price policy is used as an economic tool to promote the government's objectives of...

GENETICALLY ENGINEERED CROPS FOR PEST MANAGEMENT IN U.S. AGRICULTURE
Provedor de dados: 31
Autores: Fernandez-Cornejo,   Jorge; McBride,   William D.
Adoption of genetically engineered crops with traits for pest management has risen dramatically since their commercial introduction in the mid-1990's.  The farm-level impacts of such crops on pesticide use, yields, and net returns vary with the crop and technology examined.  Adoption of herbicide-tolerant cotton led to significant increase in yields and net returns, but was not associated with significant changes in herbicide use.  On the other hand, increase in adoption of herbicide-tolerant soybeans led to small but significant increases in yields, no changes in net returns, and significant decreases in herbicide use.  Adoption of Bt cotton in the Southeast significantly increased yields and net returns and significantly reduced insecticide use.

This paper compares factors explaining the inter-specific diversity (diversity among species) and infra-specific diversity (diversity among varieties within a species) of cereal crops grown in communities and on individual farms in the northern Ethiopian highlands.  Using named varieties and ecological indices of spatial diversity (richness, evenness, and inverse dominance), we find that a combination of factors related to the agro-ecology of a community, its access to markets, and the characteristics of its households and farms significantly affect both the inter-...

PRECISION AGRICULTURE, WHOLE FIELD FARMING AND IRRIGATION PRACTICES: A FINANCIAL RISK ANALYSIS
Provedor de dados: 31
Autores: Gandonou,   Jean-Marc; Dillon,   Carl R.
One of the main advantages of precision agriculture (PA) is its potential to increase profitability by optimizing the productivity of each section of the field. Incorporating irrigation practices to the PA technology could further increase profitability. However, investing in a complete set of precision agriculture (PA) and/or irrigation equipment represents for the average Kentuckian grain producer a substantial investment that can have a significant impact on the financial risk the he/she faces. An analysis of the consequences of that investment on the farm's cash flow and debt to asset ratio is investigated here

The Value of Accurate Crop Production Forecasts.
Provedor de dados: 31
Autores: Jayne,   Thomas S.; Rashid,   Shahidur.
Crop production forecasts are widely recognized as an important input into food balance sheets and for anticipating production shortfalls. However, the role of accurate crop production forecasting systems in mitigating food price instability and transitory food insecurity is often under-appreciated. This paper explains how crop production forecasting systems affect price instability and risks, and how they can be improved to stabilize the food system.

Estimating the public benefits of mitigating damages caused by invasive plant species in a subsistence economy
Provedor de dados: 31
Autores: Rai,   Rajesh Kumar; Scarborough,   Helen.
This paper presents analysis of a choice experiment (CE) designed to estimate willingness-topay (WTP) to mitigate damages caused by invasive plant species (IPS) in a rural community of Nepal. In order to address the cash constraints problem in a subsistence economy, two payment attributes, labor contribution and membership fee, were included in the choice sets. The results reveal that rural farmers have significant WTP for forest management activities, in terms of both cash and labor contributions. The results also suggest that rural farmers value their time in this context at a different rate to the current wage rate.

How can allocative inefficiency reveal risk preference? An empirical investigation on French wheat farms
Provedor de dados: 31
Autores: Blancard,   Stephane; Boussemart,   Jean-Philippe; Crainich,   D.; Leleu,   Herve.
We focus on a simple framework on wheat producer behaviour in a context of price output uncertainty. More precisely, we establish a relationship between ex post output price level and allocative inefficiency that allows to characterize farmers’ risk preferences. Given this analysis, the connection between risk aversion and other socioeconomic variables (such as degree of output specialisation, total asset, debts, farmer’s age…) can furthermore empirically be explored. This relationship is empirically tested on an unbalanced panel including about 650 wheat producers located in the French Department of Meuse over 1992- 2003.

Are Corn and Soybean Options Too Expensive?
Provedor de dados: 31
Autores: Urcola,   Hernan A.; Irwin,   Scott H.
A growing body of recent evidence suggests that premiums for financial options might be too high. For agricultural options, market participants often make similar claims, however there is very limited scientific literature to prove or disprove such claims. This research investigates the efficiency of corn and soybean options markets by directly computing trading returns. Time effects on market efficiency are also investigated. When the sample period is considered as a whole, risk adjusted returns indicate that no profits can be made by taking either side of the corn or soybean options markets. However, when time effects are analyzed, corn calls appear to have provided excess returns during the 1998--2005 period. This result do not appear to be driven by...

COMPARATIVE ANALYSIS OF RICE PRODUCTION COSTS IN SMALL- AND LARGE-SCALE IRRIGATED PERIMETERS IN THE UPSTREAM ZONE OF THE FLEUVE, MAURITANIA
Provedor de dados: 31
Autores: Koita,   Tocka.
Some agricultural project analysts advocate that "small-scale" perimeters are more cost effective and successful than large ones.  Patterson argues that the small scale perimeter if potentially conducive to development because of their smallness and their flexibility in terms of innovations.  Morever a recent survey irrigation in the Sahelian countries by Stryker, Gotsch, McIntire and Roche, suggests that labor intensive schemes generally have better distributional characteristics than those that are more capital intensive.  These advantages attributed to the small schemes have even biased some donors towards funding small scale perimeters. Efforts to expand rice production and therefore to increase self-sufficiency can be analyzed in terms of their...

Provides some background on concerns about the sustainability of agriculture, outlines and discusses views about what constitutes sustainable agriculture and contrasts the sustainability of modern industrialised agriculture with that of traditional agriculture. Then the question is considered (taking into account the available evidence) whether organic agriculture is more sustainable than non-organic agriculture. Barriers to switching from non-organic to organic agriculture are mentioned. The development of agriculture usually has a serious negative impact on wild biodiversity. Whether or not more intensive agriculture would reduce the negative ecological footprint is unclear but many scientists believe it will do this. Globally, there has been a rapid...

Risk premiums and GM traits
Provedor de dados: 31
Autores: Nolan,   Elizabeth; Santos,   Paulo.
An argument in favor of the development of genetically modified (GM) hybrids is that their presence is considered to be risk decreasing. On this basis, insurance premiums for corn growers in the United States who plant approved hybrids have been reduced. In this study we investigate, using a large dataset of experimental data compiled from reports of results from experimental field trials of corn hybrids by the State Agricultural Extension Services of ten universities over 20 years, whether the presence in a corn hybrid of a GM trait, or a combination of these traits, is likely to increase or decrease risk. The effects of input use on production uncertainty can be quantified through the specification and estimation of heteroskedastic production functions...

Technical Efficiency in Organic Farming: An Application on Italian Cereal Farms Using a Parametric Approach
Provedor de dados: 31
Autores: Madau,   Fabio A.
A stochastic frontier production model was applied to estimate technical efficiency in a sample of Italian organic and conventional cereal farms. The main purpose was to assess which production technique revealed higher efficiency. Statistical tests on the pool sample model suggested that differences between the two cultivation methods were significant from a technological viewpoint. Separate analyses of two sub-samples (93 and 138 observations for organic and conventional farms, respectively) found that conventional farms were significantly more efficient than organic farms, with respect to their specific technology (0.892 vs. 0.825). This implies that organic (conventional) cereal farmers could increase their income to 99.19 €/ha (40.95 €/ha). Analysis...

A BIOECONOMIC SIMULATION APPROACH TO MULTI-SPECIES INSECT MANAGEMENT
Provedor de dados: 31
Autores: Boggess,   William G.; Cardelli,   Dino J.; Barfield,   C.S.
Classical approaches to the economics of pest management have focused almost exclusively on single-species models.  This study develops and implements a methodology with which to evaluate multi-species, non-stochastic, managerial decisions subject to stochastic elements of the plant-insect system.  Multi-species insect management strategies (combinations of scouting interval, threshold value, and choice of pesticide) are analyzed using a physiological mechanistic soybean plant growth model coupled to three insect population dynamics models.  Preliminary results indicate that net returns are maximized and variance is reduced with lower thresholds and more frequent scouting than current recommendations.

ECONOMIC ANALYSIS OF TEMIK ON CITRUS IN THE INDIAN RIVER AREA IN SOUTHEASTERN FLORIDA
Provedor de dados: 31
Autores: Blakeley,   Lindsey; Weldon,   Richard N.; Fairchild,   Gary F.
Temik [R](aldicarb) is a pesticide labeled for use on several citrus crops to control rust mite, whitefly, nematode and brown citrus aphid pests. Analysis of previous research experiments indicates that this pesticide is beneficial to both orange and grapefruit production and that both cost savings and higher yields can be experienced in many types of groves. Actual grove data shows that net returns for mature grapefruit that receive Temik [R] can be $500 per acre greater than net returns for identical acreage that uses other pest control options. Also, based on grove reset data it is shown that with an application of Temik [R] the resulting increased yields for three-year-old trees more than cover the additional cost of applying the Temik [R].

The farm level economic impacts of the Farm Security and Rural Investment Act of 2002 on representative crop and livestock operations are projected in this report. The analysis was conducted over the 2001-2007 planning horizon using FLIPSIM, AFPC’s whole farm simulation model. Data to simulate farming operations in the nation’s major production regions came from two sources: - Producer panel cooperation to develop economic information to describe and simulate representative crop, livestock, and dairy farms. - Projected prices, policy variables, and input inflation rates from the Food and Agricultural Policy Research Institute (FAPRI) November 2002 Baseline. The primary objective of the analysis is to determine the farms’ economic viability by region and...

U.S. FRESH PRODUCE MARKETS:  MARKETING CHANNELS, TRADE PRACTICES, AND RETAIL PRICING BEHAVIOR
Provedor de dados: 31
Autores: Dimitri,   Carolyn; Tegene,   Abebayehu; Kaufman,   Phillip R.
Retail consolidation, technological change in production and marketing, and growing consumer demand for produce have altered the traditional market relationships between producers, wholesalers, and retailers. Increasingly, produce suppliers are asked to provide additional marketing services and incentives in exchange for volume purchases and other commitments by buyers. This report synthesizes the results from a multiphase project that examined the dynamics of produce marketing, the produce shipper-retailer relationship, and how changes in the produce market affect the relative market influence of producers, retailers, and consumers.

Privatised provision of essential plant breeding infrastructure
Provedor de dados: 31
Autores: Lindner,   Robert K.
As private plant breeding replaces public programs, the efficient provision and utilisation of key enabling technologies for crop breeding, which are largely knowledge based and provide the foundation for variety improvement, might be at risk. Typically, such inputs are non‐rival in use and are therefore termed essential plant breeding infrastructure (EPBI). Specific threats include the possibility of wasteful duplication in production, under‐production, under‐utilisation of produced EPBI because of price rationing, and anticompetitive outcomes in plant breeding and downstream markets. The likely level of under‐investment in hypothetical molecular‐marker technology by a profit‐maximising monopoly producer, charging uniform prices for access, is analysed...

Experimental Economics and the Environment: Eliciting Values for Controversial Goods
Provedor de dados: 31
Autores: Shogren,   Jason F.; Parkhurst,   Gregory M.; Hudson,   Darren.
We illustrate the experimental method by examining bidding behavior for controversial goods, i.e., goods in which bidders have positive and negative values. Our results suggest that bidding behavior differs across auction type. Bidders with positive induced values bid sincerely in a WTP auction. Bidders bid conservatively, however, in the WTA auction, foregoing profitable opportunities. Informing bidders of their optimal strategy serves to attenuate bidding discrepancies but does not eliminate them. Treating the WTP and WTA auctions as equivalent given positive and negative values could lead one to overstate the costs relative to the benefits of the controversial good.

ESTIMATING PRICE VARIABILITY IN AGRICULTURE: IMPLICATIONS FOR DECISION MAKERS
Provedor de dados: 31
Autores: Ray,   Daryll E.; Richardson,   James W.; Torre Ugarte,   Daniel de la; Tiller,   Kelly.
Using a stochastic version of the POLYSYS modeling framework, an examination of projected variability in agricultural prices, supply, demand, stocks, and incomes is conducted for corn, wheat, soybeans, and cotton during the 1998-2006 period. Increased planting flexibility introduced in the 1996 farm bill results in projections of significantly higher planted acreage variability compared to recent historical levels. Variability of ending stocks and stock-to-use ratios is projected to be higher for corn and soybeans and lower for wheat and cotton compared to the 1986-96 period. Significantly higher variability is projected for corn prices, with wheat and soybean prices also being more variable. No significant change in cotton price variability is projected.

Seasonal Analysis of Selected Fresh Fruit and Vegetable Prices at Wholesale Level in Key Urban Markets of Kenya
Provedor de dados: 31
Autores: Mathenge,   Mary K.; Tschirley,   David L.
Agricultural commodities typically show a strong seasonal pattern in production, with supplies which come off the farm during one or perhaps two distinct periods of the year having to meet relatively stable demand over the course of the entire year. This seasonal pattern in production can give rise to strong seasonal patterns in price movements, with low prices during and shortly after the harvest, rising to peaks just prior to the next harvest. Understanding this price seasonality, the typical timing and levels of seasonal highs and lows, and the reliability of each, is a key task for anyone wishing to understand the market for an agricultural commodity. This paper presents the results of seasonal analysis for seven fresh fruit and vegetable crops in...

Potential for Corn Oil Extracted from Distillers’ Dried Grain and Solubles as a Feedstock for Biodiesel
Provedor de dados: 31
Autores: Ferris,   John N.
Rising prices on vegetable oils and animal fats have enabled dry mill ethanol plants to profitably extract corn oil from distillers’ dried grain.  While the mandates under the Energy Independence and Security Act of 2007 for grain based ethanol will level off at 15 billion gallons in 2015, the mandates for biodiesel will likely continue to increase from 1.0 billion gallons in 2012 to nearly 2.0 billion gallons in 2022.  Corn oil from distillers’ dried grain can provide the needed profits and diversification of feedstock to assist the biodiesel industry in meeting the mandates.

Industrial disposal of effluents on land and the subsequent pollution of groundwater and soil of surrounding farmlands – is a relatively new area of research. The environmental and socioeconomic aspects of industrial effluent irrigation have not been studied as extensively as domestic sewage based irrigation practices, at least for a developing country like India. The disposal of effluents on land has become a regular practice for some industries. Industries located in Mettupalayam Taluk, Tamil Nadu, dispose their effluents on land, and the farmers of the adjacent farmlands have complained that their shallow open wells get polluted and also the salt content of the soil has started building up slowly.

Some ideas of economic aspects of precision plant production (protection)
Provedor de dados: 31
Autores: Takacs-Gyorgy,   Katalin.
Precision farming – besides other aspects – enables the reduction of use of chemical substances in crop production while decreases farming risks, contributes to specific field-crop-plant applications, makes production processes more designable and increases profitability. The introduction of a new technology requires complex farm-management decisions, including the consideration of economic correlations (costs-yield-income). Considering the three basic meanings of sustainability, the farming strategies have to meet these requirements. There are several alternatives to reduce artificial chemical use (applying new chemicals with lower doses, chemical-free ways like organic farming, negative environmental taxes, precision farming, etc.). In Hungary the farm...

MARKETING ASPECTS OF THE MICHIGAN POTATO INDUSTRY
Provedor de dados: 31
Autores: Fabre,   Michel.
The Michigan potato industry has undergone major transformations in the last twenty-five years.  In Michigan the number of farms harvesting potatoes in 1969 was 1.4% of what it was in 1945.  Since that date acreage in potatoes in the state decreased by two thirds.  The industry deeply felt the shift in consumption from fresh potatoes to processed potato products.  The industry has been a stagnant portion of the state agricultural economy with around 2% of the cash receipts from marketings since 1960.  Yet there are some indications that the Michigan potato industry has a good potential which could be realized, if certain modifications in the way it markets its products were implemented.  This paper focuses on the market for potatoes in their raw form, as...

THE ECONOMICS OF GENERATING AND MAINTAINING PLANT VARIETY RIGHTS IN CHINA
Provedor de dados: 31
Autores: Koo,   Bonwoo; Pardey,   Philip G.; Qian,   Keming; Zhang,   Yi.
Notwithstanding the ambiguous research and productivity promoting effects of plant variety protections (PVPs), even in developed countries, many developing countries have adopted PVPs in the past few years to comply with their Trade-Related Aspects of Intellectual Property Rights (TRIPS) obligations. Seeking and maintaining PVPs reserves options to an expected revenue stream from the future sale of protected varieties, the value of which varies for a host of reasons. In this paper we empirically examine the pattern of plant variety protection applications in China since its PVP laws were first introduced in 1997. We place those PVP rights in the context of China's present and likely future seed markets to identify the economic incentives and institutional...

Combining Biophysical and Price Simulations to Assess the Economics of Long-Term Crop Rotations
Provedor de dados: 31
Autores: Murray-Prior,   Roy B.; Whish,   J.; Carberry,   Peter S.; Dalgleish,   N.
Biophysical simulation models (e.g. APSIM) using historical rainfall data are increasingly being used to provide yield and other data on crop rotations in various regions of Australia. However, to analyse the economics of these rotations it is desirable to incorporate the other main driver of profitability, price variation. Because the context was that APSIM was being used to simulate an existing trial site being monitored by a farmer group Gross Margin output was considered most appropriate. Long-run rotational gross margins were calculated for the various rotations with yields (and other physical outputs) derived from APSIM simulations over a period of 100+ years and prices simulated in @Risk based on subjective triangular price distributions elicited...

WHAT CAN WE INFER ABOUT FARM-LEVEL CROP YIELD PDF's FROM COUNTY-LEVEL PDF's?
Provedor de dados: 31
Autores: Xu,   Zhiying.
Accurate estimates of farm-level crop yield probability density functions (PDF's) are crucial for studying various crop insurance programs and production under risk and uncertainty. Unfortunately, farm-level crop yield PDF's are difficult to estimate due to the lack of sufficient farm yield data. County yield data cover much longer time periods than farm yield data, but using county yield distributions to conjecture about farm yield distributions is dangerous. The theoretical reason is that county yield is the average of correlated farm yields, for which there is no recognizable probability density function (PDF). This paper investigates the relationship between farm and county yield distributions using both statistical theory and the Monte-Carlo...

The 1997/98 Texas-Oklahoma producer cotton markets experienced a decrease in the average producer price of almost 5.5 cents/lb. from the previous marketing year. Overall, quality was generally high and differed little from the 1996 crop. The size of the 1997 crop increased significantly, while the amount of cotton available in the spot market increased accordingly, possibly contributing to the fall in prices. With the exception of strength, discounts for the 1997 crop decreased for every quality attribute, while premiums increased for every quality attribute except staple.

Commodity Payments, Farm Business Survival, and Farm Size Growth
Provedor de dados: 31
Autores: Key,   Nigel D.; Roberts,   Michael J.
In the last 25 years, U.S. crop farms have steadily declined in number and grown in average size, as production has shifted to larger operations. Larger farms tend to receive more commodity program payments because most payments are tied to a farm’s current or historical production, but whether payments have contributed to farm growth is uncertain. This study uses farm-level data from the census of agriculture to determine whether there is a statistical relationship between farm commodity program payments and greater concentration in production. The analysis indicates that, at the regional level, higher commodity program payments per acre are associated with subsequent farm growth. Also, higher payments per acre are associated with higher rates of farm...

Marker-assisted breeding could have a major impact in relieving productivity constraints that cannot as easily or rapidly be relieved by conventional breeding alone. This paper estimates the benefits of using marker-assisted breeding, as compared to conventional breeding alone, in developing cassava varieties resistant to cassava mosaic disease, green mite, whitefly and post-harvest physiological deterioration in Nigeria, Ghana and Uganda. Marker-assisted breeding is estimated to save at least four years in the breeding cycle for varieties resistant to the pests and to result in incremental net benefits over 25 years in the range of $34 to $800 million depending on the country, the particular constraint and various assumptions. Benefits may reach as high...

Factors Affecting Hay Supply and Demand in Tennessee
Provedor de dados: 31
Autores: Bazen,   Ernest F.; Roberts,   Roland K.; Travis,   John; Larson,   James A.
Understanding the interactions between supply and demand for hay is important because of hay’s significance to the agricultural sector and economy, and because hay is an important crop on highly erodible soils. As an example, Tennessee has the most erodible cultivated cropland in the United States (Denton, 2000), nearly half of the state’s current CRP acreage contracts are set to expire in 2007 (U.S. Department of Agriculture, 2006), and hay is one of the most economically important crops produced in the state (U.S. Department of Agriculture, 2004). Cross (1999) attributed the upward trend in Tennessee hay acreage since 1980 to an increasing number of farmers who were searching for alternative production activities, such as hay, pasture and livestock, to...

The comparative advantage of dryland soybean production in Brits, North West
Provedor de dados: 31
Autores: Gronum,   C.F.; van Schalkwyk,   Herman D.; du Plessis,   J.H.
The effect of policy on the South African soybean industry is analysed, using the policy analysis matrix. The absence of effective protection from cheap imports of soy-cake and -oil, as well as the ineffectiveness of the processing industry, lead to relatively low farmgate prices of soybeans in South Africa. This could result in producers using their resources for more profitable crops, thus depriving the South African feed industry to benefit from more full fat soy in feed rations.

RICE MARKETS, AGRICULTURAL GROWTH, AND POLICY OPTIONS IN VIETNAM
Provedor de dados: 31
Autores: Goletti,   Francesco; Minot,   Nicholas.
Viet Nam has undergone a profound transformation in recent years and, as a result of a series of macroeconomic and institutional reforms since 1986, it has made substantial progress toward becoming a market economy. As this transition continues, Viet Nam faces the challenge of formulating and implementing a growth strategy which is both economically and politically feasible. Critical to this growth strategy is the role of agriculture and, within agriculture, the development of an efficient rice marketing system. The emergence of Viet Nam as a major rice exporter has raised a number of important policy questions. First, will the country be able to continue its impressive growth? Second, how far has Viet Nam moved along the path toward a market economy?...

Against the background of increasing concerns regarding the energy supply security as well as environmental concern the interest for renewable energy sources has increased in recent years. The biofuel sector, backed by public policies, experienced a strong increase in and outside Europe. A methodology that allows for the estimation of the impacts of the fulfilment of the proposed biofuel targets in the EU member states is proposed and implemented in the AGMEMOD model for France and Germany. The so called normative approach, based on the use of a logistic function as biofuel demand function allows to perform simulations to assess the impact of the biofuel demand expansion on agricultural markets. The implemented approach and the simulation results indicate...

Is There Supply Distortion In The Green Box? An Acreage Response Approach
Provedor de dados: 31
Autores: Bakhshi,   Samira; Kerr,   William A.
The shift of the farm subsidies toward programs classified as being decoupled income supports in the WTO’s URAA raises the question of their true impact on production and trade.  In this study, we measured the acreage effects of the Canadian whole farm programs under uncertainty. Based on the theoretical discussions regarding the role of the insurance effect in acreage decisions, we extend the theoretical restrictions examined by Chavas and Holt (1990)which enables us to include this effect in our model specification. Hence, we modified the expected utility maximization framework (under the hypothesis that farmers are risk averse) developed by Chavas and Holt (1990) and derived three distinct effects: market effects, the wealth effect, and the insurance...

The farm level economic impacts of the Farm Security and Rural Investment Act of 2002 are projected for representative Texas cotton farms. The analysis was conducted over the 2001-2008 planning horizon using FLIPSIM, AFPC’s whole farm simulation model. Data to simulate farming operations in Texas’ major cotton production regions came from two sources: - Producer panel cooperation to develop economic information to describe and simulate representative cotton farms. - Projected prices, policy variables, and input inflation rates from the Food and Agricultural Policy Research Institute (FAPRI) August 2004 Baseline. The primary objective of the analysis is to determine cotton farms’ economic viability by region through 2008, assuming provisions of the 2002...

The Agricultural and Food Policy Center (AFPC) at Texas A&amp;M University develops and maintains data to simulate eleven representative cotton operations in major production areas across Texas. The chief purpose of this analysis is to project those farms’ economic viability for 2005 through 2009. The data necessary to simulate the economic activity of these operations is developed through ongoing cooperation with panels of agricultural producers throughout the state. The Food and Agricultural Policy Research Institute (FAPRI) provided projected prices, policy variables, and input inflation rates in their August 2005 Baseline. Under the August 2005 Baseline, none of the Texas representative cotton farms are classified in good liquidity condition (less than...

Irrigation Decision Rules for Cottongrowing in the Brookstead Area of the Darling Downs
Provedor de dados: 31
Autores: Nuthall,   Peter L.
A decision problem faced by cottongrowers using irrigation is that of deciding the soil moisture level at which irrigation should occur. A simulation model was developed so that the effect on cotton yield of irrigation at different soil moisture levels could be explored. The output from the model was used to develop relationships enabling the determination of an optimal decision rule. The results indicate that under most situations heavy irrigation in the period "first open flowers to first open bolls" will be profitable.

Effects of Government Maize Marketing and Trade Policies on Maize Market Prices in Kenya
Provedor de dados: 31
Autores: Jayne,   Thomas S.; Meyers,   Robert J.; Nyoro,   James K.
The objectives of this paper are to determine the effects of NCPB maize trading activity and the maize import tariff on wholesale maize market price levels and volatility. The analysis uses monthly maize price and trade data covering the period January 1990 to September 2004. Results are based on a vector autoregression (VAR) approach that allows estimation of a counterfactual set of maize prices that would have occurred over the 1990-2004 period had the NCPB not existed and trade restrictions been removed. Assessed are the separate impacts of policy on wholesale prices in Kitale, a major surplus-producing area, and Nairobi, the major urban demand center in the country.

Autores: Arouna,   Aminou; Adegbola,   Patrice Ygue; Adekambi,   Souleimane Adeyemi.
This study contributes to the debate regarding the competitiveness of developing countries in the context of globalization. To take advantage of this trend, developing countries will have to position themselves properly through new policies and efficiency in production. In Benin, new orientation of agricultural policy concerns the diversification of exported products. Therefore, and due to the decrease of international price of cotton which represents the main exported crop, cashew nut, the second exported crop by Benin, becomes more interesting for government policy. The study quantified cashew nut production farmers’ efficiency using a stochastic production frontier and a cost function combined with numerical classification. Primary data were collected...

Behavior of subsistence producers in response to technological change- The elasticity of cassava production and home consumption in Benin
Provedor de dados: 31
Autores: Takeshima,   Hiroyuki.
The welfare effects of GM (genetic modification)-led productivity growth for cassava producers are partly affected by the characteristics of individual cassava producing households. Those household characteristics include the elasticity of production and home consumption of cassava. Some studies assume the inelastic home consumption when conducting ex-ante welfare effects analysis for subsistence crops. This study modifies the estimation methods used in the past literature to estimate both elasticities using the dataset from Benin. Several assumptions are also tested regarding the heterogeneity of cassava producers. On estimation of elasticities, the paper tests the hypothesis that on-farm sellers are characteristically different from off-farm sellers by...

Autores: Parhusip,   Uben.
Indonesia is an agrarian country with more than seventy percent of her population living in rural areas.  The population of Indonesia was 119.2 million in 1971 with a very high growth rate.  This population is not evenly distributed, with 63.8 percent of the population concentrated in the Java and Bali Islands, which is only about seven percent of the total area of Indonesia.  Java is recognized by its crowded rural region, high unemployment and therefore low standard of living for the rural area.   Indonesian economy is still an agrarian economy, with more than fifty percent of national income from agriculture, with low productivity in traditional techniques of production and very small holding size.  Rice holds a dominant position in both production and...

Accuracy and Asymmetry of Corn, Soybean and Wheat Interval Forecasts
Provedor de dados: 31
Autores: Isengildina-Massa,   Olga; Sharp,   Julia L.; Zhang,   Jing; Campbell,   Wallace A.
This study evaluates the accuracy of USDA interval forecasts for corn, soybean, and wheat prices using Christoffersen’s (1998) tests for unconditional coverage, independence and conditional coverage adjusted for asymmetries in tail probabilities. The findings of this study demonstrate that due to uneven distribution of forecast misses around the interval, calibration of soybean price forecasts in several cases was rejected by basic coverage tests (suitable for symmetric intervals) but not rejected by the tests adjusted for asymmetry. Thus these forecasts were asymmetric but accurate. Symmetry was not a limiting assumption for corn and wheat interval forecast accuracy.

Autores: Williams,   Jeffery R.; Tanaka,   Donald L.; Herbel,   Kevin L.
Relationships among topsoil removal treatments and additions of nitrogen and phosphorus fertilizer in spring wheat yields are used to determine the effects on net returns and to estimate the marginal value of soil. The results indicate that risk-averse managers are not willing to make an expenditure for controlling erosion from the first 2.5 inches of soil if the erosion rate is 20 tons/acre/year or less and the planning horizon is 20 years or less. These managers would be willing to make an erosion control investment for the second 2.5 inches of soil equivalent to $4.90 to $5.20/acre from the twenty-first to forty-third year in the planning horizon.

THE ADEQUACY OF TRUCKING SERVICE SUPPLIES FOR PRODUCE: TRENDS IN THE 1980S
Provedor de dados: 31
Autores: Beilock,   Richard P.; Dunton,   William; Kepler,   Paul.
Over 90 percent of interstate produce movements are by truck.  In recent years, concerns have been raised regarding the adequacy of motor carrier services.  Reasons for these concerns include the possibility of increased costs or service erosions resulting from relaxed economic regulations, an eroding road infrastructure, increasing congestion, more stringent safety regulations, demographic trends suggesting the onset of an increasingly severe driver shortage, and declines in rail capacity devoted to produce haulage.  In this study, trends in the adequacy of trucking services for trucking during the 1980s was examined employing data sets developed by the USDA regarding haulage from five growing areas to six metropolitan areas across the United States, and...

A mixed-integer programming model is developed to assess the economic feasibility of siting a woody biomass-based ethanol facility in the central Appalachian hardwood region. The model maximizes the net present value (NPV) of a facility over its economic life. Model inputs include biomass availability, biomass handling system type, plant investment and capacity, transportation logistics, feedstock and product pricing, project financing, and taxes. Four alternative woody biomass handling systems, which include all processes from stand to plant, are considered. Eleven possible plant locations were identified based on site selection requirements. Results showed that the optimal plant location was in Buckhannon, West Virginia. The NPV of the plant with a...

Autores: Ulimwengu,   John M.; Funes,   Jose; Headey,   Derek D.; You,   Liang.
Given its vast land resources and favorable water supply, the Democratic Republic of Congo's (DRC) natural agricultural potential is immense. However, the economic potential of the sector is handicapped by one of the most dilapidated transport systems in the developing world (World Bank, 2006). Road investments are therefore a high priority in the government's investment plans, and those of its major donors. Whilst these are encouraging signs, very little is known about how the existing road network constrains agricultural and rural development, and how these new road investments would address these constraints. To inform this issue the present paper primarily employs GIS-based data to assess the impact of market access on agricultural and rural...

Prospects for adopting system of rice intensification in Sri Lanka: A socioeconomic assessment
Provedor de dados: 31
Autores: Namara,   Regassa E.; Weligamage,   Parakrama; Barker,   Randolph.
Today, there is an increasing worldwide interest in assessing the potential for maintaining or increasing rice yields by reducing or eliminating the use of chemicals and by decreasing irrigation requirements. The System of Rice  Intensification (SRI) first developed in Madagascar and now being tested in many countries, is an example of such an approach. The system is based largely on organic farming principles and additional requirements for spacing and the transplanting of seedlings.

Fusarium Head Blight (FHB), commonly known as scab, has been a severe problem for wheat and barley producers since 1993.  This study provides an update of economic losses suffered by wheat and barley producers in scab-affected regions in the United States.  Emphasis is placed on estimating direct and secondary economic impacts of yield and price losses suffered by wheat and barley producers from 1993 to 2001.   Nine states are included in the analysis for three wheat classes.  Three of the nine states were also used for the analysis of malting and feed barley.  The cumulative direct economic losses from FHB in hard red spring (HRS) wheat, soft red winter (SRW) wheat, durum wheat, and barley are estimated at $2.492 billion from 1993 through 2001.  The...

Small forests, big ambitions and a hard reality - Community Forestry in Nepal
Provedor de dados: 31
Autores: Rai,   Chandra; Bigsby,   Hugh R.; MacDonald,   Ian.
Community forestry in Nepal is intended to reduce poverty by sustainable management of forests. Timber is one of the most high-value forest products, especially in the case of Sal (Shorea robusta) forests in the Terai region of Nepal. Despite having several advantages, including high value forests on fertile land, connection with transportation networks, and being close to regional markets, community forests in the Terai region produce little or no timber from their Sal forests. This research looks at what is affecting the production of Sal timber from community forests. Three aspects of community forest user groups (CFUG) are examined using institutional economics, transaction cost economics and micro-economics. First, the scale of CFUG operations is...

FORECASTING CROP QUALITY
Provedor de dados: 31
Autores: Ryland,   G.J.
The need for a forecasting system of biological quality arises as a result of the price-quality payment schemes in grower and processor contracts which operate in many agricultural cropping industries. The seasonal nature of the series of vertical quality height gives rise to questions as to the repetitive pattern of the shape and trend translation of the series. These hypotheses can be tested using conventional statistical methods. For non-stationary series, however, a Box-Jenkins type dynamic seasonal model is proposed. These forecasting procedures are applied to a series of sugar cane quality.

DOES CASH CROP ADOPTION DETRACT FROM CHILDCARE PROVISION? EVIDENCE FROM RURAL NEPAL
Provedor de dados: 31
Autores: Paolisso,   Michael J.; Hallman,   Kelly K.; Haddad,   Lawrence James; Regmi,   Shibesh.
Using data from fieldwork conducted in Nepal, the impact of a project designed to commercialize vegetables and fruits—the Vegetable and Fruit Cash Crop Program (VFC)—on male and female time allocation is examined. Using a rigorous time collection methodology, activity patterns in households that adopt and do not adopt the new technology are profiled. Very few studies examine changing activity patterns of both men and women in response to commercialization of agriculture. Though women’s time is valuable in agriculture, it is also valuable in the production of child nutrition. The recent evolution in thinking as to the causes of child malnutrition—the three pillars being food intake, health, and time to care—warrants further analyses of the time trade-offs...

Investment Spikes in Dutch Horticulture: An Analysis at Firm and Aggregate Firm Level Over the Period 1975-1999
Provedor de dados: 31
Autores: Goncharova,   Natalia V.; Oskam,   Arie J.
An intermittent and lumpy pattern of investments is observed in the Dutch horticulture sector: only 16.5% of firms experience of investment spike, but they account for 67.7% of total investment. The objective of this paper is to examine the impact of time-varying and time-invariant variables on the probability of observing an investment spieke. This paper investigates the spells between investment spikes in a discrete-time proportional hazard framework. Duration models were estimated on two data sets: on an unbalanced panel and on a grouped into 10 groups data of Dutch glasshouse firms over the period 1975-1999. Different specifications of the model were estimated. Theoretically based model can sufficiently explain the occurrence of investment spikes. Both...

Feed grains researchers have abundant technical opportunities to select various options for improvement of nutritional characteristics of feed grains. Choosing between those opportunities is a difficult issue for research funding organisations. In this paper, efforts to address the relative economic benefits from the different options for feed grains nutritional improvement are reported. The economic benefits arising from nutritional improvements in various feed grains are examined and compared to the benefits from increasing yields of the feed grains rather than improving their nutritional value. The results of the analysis of these options are presented in an economic surplus framework that enables the major beneficiaries and the relative gains for the...

Autores: Dinar,   Ariel; Yaron,   Dan.
This article describes the influence of input quality and scarcity, environmental conditions, human capital, water price, and other variables on adoption rates for modern irrigation technologies in terms of both speed and extent of application. An empirical model is developed to apply these relationships to citrus groves in Israel. Results show that modern irrigation technologies tend to be adopted sooner and to a greater extent (a) on groves located on relatively low quality land, (b) in regions with higher evaporation rates, (c) on groves planted with more sensitive rootstock, and (d) on groves grown under conditions of restricted water allotments and higher water prices. Management, human capital, and scale of operation also affect the level and speed...

Hungarian agricultural production plays a significant role in the preservation of rural areas, in its sustainable development, and in lessening the regional differences. The value of our agricultural sector is primarily provided by the combination of favourable climate, good natural makings and growth traditions. The effectiveness of our crop growing greatly depends on our most important plant cultures such as for example the results wheat growing. In our country wheat growing has a traditional importance in the plant growing branch since centuries, it is grown on most farms. The basic purpose of our analytic work was to compare the results of wheat growing based on the production results collected by us concerning wheat growing in Hungary and Austria....

BOUNTIES FOR FERTILIZERS
Provedor de dados: 31
Autores: Mauldon,   Roger G.
Bounty payments on fertilizers have rapidly emerged as a major form of assistance to Australian agriculture. They have been justified as a way of reducing costs and increasing productivity, though economic theory and experience from agricultural production studies suggest that they achieve these objectives inefficiently. The bounties are directed towards making acres more productive, which should in turn make farmers more productive. It is suggested that greater economic welfare would result from tackling the problem the other way round.

Intellectual Property Regimes (IPRs) have been justified on the basis that they promote innovation, but it is not always clear that they do so. Empirical studies of IPRs in an Australian context have been limited. Plant variety protection is one form of IPR. The passing of the Australian Plant Breeder’s Rights Act of 1994 has been followed by significant commercialisation of the wheat breeding industry. The purpose of this paper is to consider whether this commercialisation has benefited wheat productivity through varietal improvement. We estimate a linear crop production function, using a random effects Hausman Taylor estimator to evaluate differences in genetic contributions to productivity between public and private wheat varieties commercially released...

The Agricultural &amp; Food Policy Center (AFPC) updated the comparison of corn and sorghum county loan rates following the general methodology outlined in the October 2002 Food and Agricultural Policy Research Institute (FAPRI) study on corn and sorghum loan rates. The study answers two questions: 1. Are the 2006 county loan rates established by USDA consistent with the Congressional mandate that national average loan rates for both commodities be $1.95 per bushel? 2. What would be the impact if USDA were to adopt a different weighting scheme in setting county loan rates while continuing to maintain the mandated national average loan rate? Specifically, what would be the impact on sorghum loan rates if each county’s loan rate were weighted by the county’s...

ECONOMIC VIABILITY OF BT-CORN IN THE U.S.
Provedor de dados: 31
Autores: Kim,   Hong Jin; Konyar,   Kazim; Sargent,   Keith.
Bt-corn, a genetically engineered insect resistant variety, has been adopted by almost one-quarter of all corn farmers, resulting in economic impacts on both conventional corn growers and Bt-corn growers.  we estimate changes in profits for both types of farmers with different levels of seed premiums, yield increases and adoption rates.  We find that Bt-corn growers will see their profits decline when the adoption rate and seed premium are high, if they are not offset by higher yields.  Conventional corn growers will always experience a decline in profits because the yield increase from Bt-corn causes corn price to fall.

The Asymmetric Cycling of U.S. Soybeans and Brazilian Coffee Prices: An Opportunity for Improved Forecasting and Understanding of Price Behavior
Provedor de dados: 31
Autores: Ramirez,   Octavio A.
The behavior of agricultural commodity markets can arguably result in markedly asymmetric price cycles, that is, downward cycles of substantially different length and breadth than upward cycles. This study assesses whether asymmetric-cycle models can enhance the understanding of the dynamics and provide for a better forecasting of U.S. soybeans and Brazilian coffee prices. The forecasts from asymmetric cycle models are found to be substantially mode precise than those obtained from standard autoregressive models. The asymmetric cycle models also provide useful insights on the markedly different dynamics of the upward versus the downward cycles exhibited by the prices of these two commodities.

LOGISTICAL COSTS AND STRATEGIES FOR WHEAT SEGREGATION
Provedor de dados: 31
Autores: Schlecht,   Shannon M.; Wilson,   William W.; Dahl,   Bruce L.
Special segregations that provide unique qualities for end use products are being specified by buyers.  As users of wheat become more specific about quality, the number of quality segregations that the logistical pipeline must accommodate increases.  The additional cost of increased grain segregations will influence the optimal level of wheat variety segregations marketed in a supply chain.    The primary objective of this research is to develop a model that captures the logistical costs of increased grain segregations in the marketing system.  A simulation model was developed to add logistical uncertainty in demand, receipts, rail deliveries, and transit time.  Sensitivities were conducted on certain variables to determine their effects on logistical...

Can virtual water 'trade' reduce water scarcity in semi-arid countries? The case of Spain
Provedor de dados: 31
Autores: Garrido,   Alberto; Novo,   Paula; Rodriguez Casado,   Roberto; Varela-Ortega,   Consuelo.
Agricultural trade is by far the largest vehicle to ‘move’ water virtually around the world. Observing that most countries import and export water embedded in the exchanged products, the objective of this study is to assess the virtual water ‘trade’ in Spain for the period 1997-2006. We differentiate between the green and blue components of virtual water from a hydrological and economic perspective. The combination of spatial and time dimensions offers a unique empirical setting to determine whether virtual water ‘trade’ can contribute to reduce water scarcity. The study reveals that Spain is a net ‘importer’ of virtual water. By far the largest virtual water ‘imports’ are linked to cereals and animal feed products whilst the virtual water ‘exports’ are...

The effect of nine different fungicide seed treatments for soybeans were tested from 2004 to 2007 at Keiser, Stuttgart, and Hope, Arkansas. While seedling emergence was effective across all treatments, only three treatments showed statistically significant differences in partial returns, defined as gross revenue minus seed and seed treatment costs. Comparisons of the regret a producer would experience as a result of non-optimal seed treatment suggested that broad spectrum seed treatment could enhance profitability by an average of $32 per acre with similar treatment recommendations across a range of seeding rates, output prices and study conditions.

A Return of the Threshing Ring? A Case Study of Machinery and Labor-Sharing in Midwestern Farms
Provedor de dados: 31
Autores: Artz,   Georgeanne M.; Colson,   Gregory; Ginder,   Roger G.
Machinery-sharing provides an alternative for smaller producers to obtain the efficiencies of large farming operations and remain competitive in an increasingly concentrated agricultural industry. This research uses a multiple case study design to examine the motivations for sharing equipment and labor among farms and to better understand how group members handle the transaction costs of sharing. Our case evidence finds that in addition to cost savings, access to reliable labor is an important motivation for participating in a sharing arrangement. Trust and frequent communication among group members helps to minimize the transaction costs incurred from sharing.

Irrigation Restriction and Biomass Market Interactions: The Case of the Alluvial Aquifer
Provedor de dados: 31
Autores: Popp,   Michael P.; Nalley,   Lawton Lanier; Vickery,   Gina B.
The U.S. Geological Survey has determined that irrigation in Arkansas’ Delta is unsustainable. This study examines how irrigation restrictions would affect county net returns to crop production. It also considers the effect of planting less water-intensive bioenergy crops—switchgrass and forage sorghum—in the event biofuel markets become a reality. Results suggest that sustainable irrigation restrictions without bioenergy crops would decrease producer returns by 28% in the region. Introducing these alternative crops would both reduce groundwater use and may restore state producer returns, albeit with significant spatial income redistribution to crop production throughout the state.

Dynamic Optimization of Fertilizer Application with Carryover and Runoff
Provedor de dados: 31
Autores: Zhou,   Xia (Vivian); Clark,   Christopher D.; Lambert,   Dayton M.
The Economics of fertilizer application has been an interesting issue in regard to crop production (Kennedy et al., 1973). Understanding the temporal dynamics complicates the issue along two dimensions: fertilizer carryover and fertilizer runoff. Fertilizer carryover measures the amount of fertilizer applied in the previous period that is available for crops in current growing period (Kennedy et al., 1973). Fertilizer runoff refers to fertilizer leaving the ground and flowing into water bodies. Thus, the optimal quantity of fertilizer to be applied in the current period depends on the amount of previous application, runoff, and carryover. Because fertilizer carryover and runoff makes optimization of application a complicated intertemporal problem, static...

Do Refuge Requirements for Biotechnology Crops Promote Economic Efficiency? Some Evidence for Bt Cotton
Provedor de dados: 31
Autores: Livingston,   Michael J.; Storer,   Nicholas P.; Van Duyn,   John W.; Kennedy,   George G.
We examine producer behavior, resistance evolution, and returns under alternative refuge requirements in an eastern North Carolina region with multiple corn, cotton, and soybean fields infested by a mobile pest. Returns are highest, pyrethroid sprays occur least frequently, and pyrethroid resistance evolution is delayed most effectively with no refuge requirement. Complying with the current 20% refuge requirement costs the producer $8.67 per cotton acre, or $34.21 per non-transgenic insecticidal (Bt) cotton acre. Returns are highest under each refuge requirement when one-toxin Bt cotton is not phased out; however, removal of the technology at the earliest phase-out date minimizes regional pyrethroid sprays.

The Effects of Strengthened IPR Regimes on the Plant Breeding Sector in Developing Countries
Provedor de dados: 31
Autores: Eaton,   Derek J.F.; Tripp,   Robert; Louwaars,   Niels P.
This paper analyzes the effect of intellectual property rights (IPR) regimes on the plant breeding sector in developing countries. Most of these countries have implemented a system of plant variety protection (PVP), or are in the process of doing so, generally as part of their obligations under the Agreement on Trade Related Aspects of Intellectual Property (TRIPS) of the World Trade Organization (WTO). This paper presents the results of research on the initial effects of IPRs on the plant breeding sector in five case study countries (China, Colombia, India, Kenya and Uganda). Three of the countries have PVP systems in place and the other two are in the process of either developing or implementing legislation. But the ease of implementing PVP seems to have...

Inputs use in the agriculture of Emilia-Romagna: farm comparison through the Total Factor Productivity (TFP) index
Provedor de dados: 31
Autores: Ghelfi,   Rino; Bertazzoli,   Aldo; Marchi,   Alan; Rivaroli,   Sergio; Samoggia,   Antonella.
In order to measure agriculture sustainability, the efficient use of inputs becomes a crucial issue. In this perspective, the analysts concentrate their attention on the total factor productivity index (TFP). In this view, Lynam and Herdt (1989) proposed the TFP as a suitable assessment of the sustainability of single crops, of cropping systems or of farming systems. Even if the TFP does not take into account the non-market output (social and environmental aspects), it is possible to argue that a negative trend of TFP represents a resources’ degradation if related to the generated outputs. On the other hand, the non-negative trend of TFP represents a fitting measure of a sustainable agricultural system and of an efficient use of the resources. The aim of...

A Dynamic Programming Approach to the Economic Control of Weed and Disease Infestations in Wheat
Provedor de dados: 31
Autores: Fisher,   Brian S.; Lee,   R.R.
Weeds and fungal diseases cause significant losses to grain crops in Australia. In many cases cultural methods of control are effective. However, it is often difficult for farm decision-makers to select the optimum crop rotation, from an economic point of view, given the technical constraints they face. A decision to plant a particular crop will have implications for both current and future profitability because the current decision will alter the constraints faced by the decision-maker in subsequent periods. Dynamic programming is used to solve the rotation problem faced by grain growers in north-western New South Wales in areas where the weed, wild oats (A vena falua or A vena ludoviciana), and the disease, crown rot (Fusarium graminearum Group I), have...

Stocker cattle grazing warm season perennial grasses is an important economic activity in the southern Great Plains.  Substantial increases in the price of nitrogen fertilizer is negatively affecting forage producers’ profitability.  Two alternative nitrogen management systems that use annual and perennial legumes have been developed for bermudagrass pastures.  The goal of the study is to determine if the legumes systems are more profitable than the conventional practice of applying synthetic sources of nitrogen.  Results of the two-year grazing study show that the legume systems could not compete economically with the common practice.

Incentives for Fertilizer Use in Sub-Saharan Africa: A Review of Empirical Evidence on Fertilizer Response and Profitability
Provedor de dados: 31
Autores: Yanggen,   David; Kelly,   Valerie A.; Reardon,   Thomas; Naseem,   Anwar.
This research addresses two questions: Why is fertilizer not yet fulfilling its potential as a major stimulus to agricultural productivity in SSA? What can be done to improve the situation? Our answers are based on an extensive review of fertilizer response, profitability, and policy literature as well as some analysis of crop budgets and aggregate national statistics on fertilizer consumption. Much of the debate about fertilizer use in SSA focuses on two issues: whether the profit incentive is adequate and, if so, whether farmers have the capacity to access and use it.

Counterproductive Counternarcotic Strategies?
Provedor de dados: 31
Autores: Andersson,   Camilla I.M.
We model the economic incentives surrounding opium crop production in Afghanistan. Specifically, we examine the impact of eradication policies when opium is used as a means of obtaining credit, and when the crops are produced in sharecropping arrangements. The analysis suggests that when perfect credit markets are available, an increased risk of eradication will lead to less land being allocated to opium poppy. However, when opium is used as a means of obtaining credit, the effects of eradication are no longer clear-cut. Finally, under sharecropping arrangements, increased risk of eradication will make the tenants worse off, while landlords may benefit.

Technological Innovation and Efficiency in the Nigerian Maize Sector: Parametric Stochastic and Non-parametic Distance Function Approaches
Provedor de dados: 31
Autores: Aye,   Goodness C.; Mungatana,   Eric D.
The current food crisis all over the globe has necessitated alternative policy actions by various stakeholders in almost all countries of the world. Consequently, efforts are focused on increased investment in agricultural research and development. The study evaluates impact of technological innovations on estimates of technical, allocative and cost efficiency from a parametric stochastic and non-parametric distance functions. Inefficiency effects are modelled in a second stage endogeniety-corrected Tobit regression model as a function of technological innovation and other policy variables. The results from both approaches show there is substantial technical, allocative and cost inefficiency in maize production and that analysis of technical, allocative...

Autores: Dimithe,   Georges; Bernsten,   Richard H.; Staatz,   John M.; Coulibaly,   B.S.; Mariko,   Dramane; Kergna,   Alpha O.
The high costs of rehabilitating and/or expanding government-managed irrigated schemes in Mali (Office du Niger) has prompted policy-makers and researchers to explore the potential for the underdeveloped farmer-managed bas-fond  to contribute to ensure an adequate rice supply and increase rural households' incomes.  Because little is known about nas-fond rice production in Mali, this paper analyzes its financial profitability based on data collected from a random sample of 221 farmers.  Data analysis revealed that there are numerous rice production systems in the bas-fond.  Budget analysis showed that the four most common bas-fond production systems yield higher returns than the opportunity cost of labor and they are more profitable than the main upland...

Farmers’ Subjective Perceptions of Yield and Yield Risk
Provedor de dados: 31
Autores: Egelkraut,   Thorsten M.; Sherrick,   Bruce J.; Garcia,   Philip; Pennings,   Joost M.E.
Using survey responses of Illinois corn farmers to differently framed yield questions, we examine their subjective information by relating stated yields and risk to the corresponding objective county measures.  The results show that farm-level yields can be best characterized by soliciting probabilistic information, which provides more accurate yield assessments than an open-ended frame and consistent estimates of producers’ subjective risk.  Moreover, we find that overconfidence can be confused with differences in relevant information and that using recent data may be more appropriate in examining subjective risk statements.  Our results are important for agricultural policy-makers and researchers, particularly those who work with surveys that include...

This study explores the constraints on agricultural productivity and priorities in boosting productivity in rice, the main staple in Madagascar, using a range of different data sets and analytical methods, integrating qualitative assessments by farmers and quantitative evidence from panel data production function analysis and willingness-to-pay estimates for chemical fertilizer. Nationwide, farmers seek primarily labor productivity enhancing interventions, e.g., improved access to agricultural equipment, cattle and irrigation. Shock mitigation measures, land productivity increasing technologies and improved land tenure are reported to be much less important. Poorer farmers have significantly lower rice yields than richer farmers, as well as significantly...

Costs and Benefits to Taxpayers, Consumers, and Producers from U.S. Ethanol Policies
Provedor de dados: 31
Autores: Babcock,   Bruce A.; Barr,   Kanlaya J.; Carriquiry,   Miguel A.
The U.S. ethanol industry is lobbying hard for an extension of existing ethanol import tariffs and blenders tax credits before they expire at the end of 2010. The purpose of this study is to examine the likely consequences on the U.S. ethanol industry, corn producers, taxpayers, fuel blenders, and fuel consumers if current policy is not extended. Impacts of different ethanol policies in both 2011 and 2014 were estimated.  Estimates were obtained by developing a new stochastic model that calculates market-clearing prices for U.S. ethanol, Brazilian ethanol, and U.S. corn. The model is stochastic because market-clearing prices are calculated for 5,000 random draws of corn yields and wholesale gasoline prices.   Key assumptions in this study are that the...

Autores: Ben Salk,   Sana; Blondel,   Serge; Daniel,   Christophe; Deffains-Crapsky,   Catherine; Jutard,   Catherine; Sejourne,   Bruno.
In agriculture, there is need for a deeper analysis of management of climate risks, because the farmers appear to have a paradoxical position: they perceived that they are strongly exposed to climate risks but, they do not want to pay for adapted tools, arguing that this is too expensive or complex. However, under risk, it is well-known that the decision-makers could be subject to paradox (Allais for example). Our assumption is that to know better the behaviours of farmers in general risky situations will help to understand their reluctance to use the weather market. We conducted a study over the wine growers in the Maine-et-Loire department. 60 wine growers have responded to the questionnaire about climate risk management, and 29 amongst them have...

Contracts for Grain Biosecurity and Grain Quality
Provedor de dados: 31
Autores: Abougamos,   Hoda; White,   Benedict; Sadler,   Rohan.
The export of grain from Western Australia depends upon a grain supply network that takes grain from farm to port through Cooperative Bulk Handling receival and storage sites. The ability of the network to deliver pest free grain to the port and onto ship depends upon the quality of grain delivered by farmers and the efficacy of phosphine based fumigation in controlling stored grain pests. Phosphine fumigation is critical to the grain supply network because it is the cheapest effective fumigant. In addition, it is also residue free. Unfortunately, over time, common stored-grain pests have evolved to develop resistance to phosphine and there is a risk that phosphine will become less effective and may need to be replaced with more expensive alternative...

Profitability and Resource Allocation Among Cotton and Peanuts When Considering Planting and Harvest Timeliness
Provedor de dados: 31
Autores: Meeks,   Timothy A.; Flanders,   Archie; Shurley,   W. Donald; White,   Fred C.; Gunter,   Lewell F.
Harvest timeliness is a continual problem in rotation of cotton and peanuts.  Efficient allocation of land and labor resources during production of cotton and peanuts requires decisions be made on allocating resources throughout the growing season. Of particular concern is efficient allocation during planting and harvesting.  Through economic analysis and linear programming optimization, planting and harvesting timeliness issues are addressed and compared with prevailing practices.  Results for a representative farm indicate that cotton planting should increase during the early period of the planting season as compared with current practice, and most cotton should be harvested before peanut harvest begins.

This note presents the situation of the Malian cotton sector as of 2001/02, with emphasis on the possibility of emerging from the crisis at that time. ] The CMDT, the Malian company for textile development, has as its mission the production, storage, and marketing of cotton. Despite excellent performance over the years, CMDT was faced by a major crisis in 1999/2000 which has persisted. Cotton is very important to the Malian economy. The area of the cotton zone is about 163,303 km2, and included a population of about 3.8 million in 2000. Income from cotton was 96.5 billion CFA francs in 1998/99. However, since the 1999/00 campaign, the producers’ income decreased, falling to 41.3 billion CFA francs in 2000/01. Since the devaluation of the CFA franc in...

Aerobic Rice: Benefits without going to the Gym?
Provedor de dados: 31
Autores: Bayot,   Ruvicyn; Templeton,   Deborah J.
Rice, a staple food for over 70% of Asians, is also the single biggest user of water, requiring 2‐3 times more water per unit of grain produced than crops such as wheat and maize. With growing populations, increased urbanisation and environmental degradation, the supply of fresh water is depleting. Recognising the water constraints to rice yield, the aim of the project entitled ‘Developing a System of Temperate and Tropical Aerobic Rice (STAR) in Asia’ was to develop water‐efficient aerobic rice technologies. This paper highlights the success of that project.

Pulse Policy Reform in India: Implications for Trade, Prices and Production, 1970-1999
Provedor de dados: 31
Autores: Agbola,   Frank W.
India is a major producer and consumer of pulses in the world. In the last two decades, India’s pulse economy has undergone major policy and institutional reforms. These changes are likely to influence India’s trade in pulses and consequently world pulse trade. This article examines the impact of these reforms on trade, prices and production in India. The article discusses the factors that instigated these policy reforms and the consequences. The results indicate that a number of key economic, political and technological factors are reshaping pulse trade in India. The policy implications of the findings are explored.

Shifting from Agriculture to Agribusiness: The Case of Aromatic Plants
Provedor de dados: 31
Autores: Mittal,   Rashi; Singh,   S.P.
This study has examined the agribusiness opportunities in medicinal and aromatic plants (MAPs), based on the field level information from the state of Uttarakhand. The financial feasibility of important aromatic plants has been studied. It has been found that the returns are substantially higher from these crops than the most profitable commercial crops like sugarcane. The study has identified the constraints that affect the spread of cultivation of MAPs; these include inadequate processing capacities, price risks and non-availability of planting material. It has been suggested that concerted efforts should be made to address these constraints and increase access to the world market.

Globalization of Fresh Fruit Products: The Role of Public Agencies and the Transformation of the Petrolina-Juazeiro Valley
Provedor de dados: 31
Autores: Valente,   Airton Saboya Junior.
Fresh fruits became one of the most globalized products within the agricultural sector. Different factors have contributed to propel this trend, such as cost reduction in transportation, improvement in cold chain facilities and changes in dietary habits. Production of fresh fruits for export has grown in Brazil, and it is present in over 30 production hubs. The Brazilian Northeast became one of those focal points, where its fruit production and exports come mainly from irrigated valleys, such as the Petrolina-Juazeiro one. Fruit exports have contributed to transform the Petrolina-Juazeiro valley: they have attracted producers, agribusiness firms, services companies, undergraduate schools, machinery and farm implement manufactures. Besides that, the job...

This report summarizes the financial and production records of 18 Michigan tree fruit farms. To be included, the farms must have produced at least 50 percent of gross cash farm income from one or a combination of sales from cherries, apples, and other fruits. The records came from Michigan State University's TelFarm/MicroTel project, the Farm Credit Service system, or by AgriSolutions in Michigan. The values were pooled into averages for reporting purposes.  Farm records were included if a farm financial summary was completed on 2002 data including beginning and ending balance sheets, plus income and expenses. The data was checked to verify that cash and debt discrepancy were within an acceptable range. While considerable variation in the data exists,...

Price Discrimination in the Context of Vertical Differentiation: An Application to Canadian Wheat Exports
Provedor de dados: 31
Autores: Lavoie,   Nathalie.
This study examines the ability of the Canadian Wheat Board (CWB) to price discriminate in bread wheat exports. This study models wheat as a vertically differentiated intermediate good and modifies the model of vertical differentiation by Mussa and Rosen to the realities of wheat import demand. The conceptual model isolates the bases of price discrimination and demonstrates that the CWB’s ability to exploit cost differences in pricing depends on the extent of the differentiation between Canadian and U.S. wheat. This model is implemented using monthly confidential price data provided by the CWB for exports to Japan, the United Kingdom, and two markets aggregating remaining exports through Canada’s west and east coasts, for 1982 1994.  The data indicate that...

Comparing the profitability of sheep, beef, dairy and grain farms in southwest Victoria under different rainfall scenarios
Provedor de dados: 31
Autores: Browne,   Natalie; Kingwell,   Ross S.; Behrendt,   Ralph; Eckard,   Richard.
Dryland farming is commonplace in Australia so the profitability of dryland farms often depends on the amount and timing of rainfall. With drier weather conditions featuring in climate change projections for southern Australia, it is important to understand the relationships between rainfall, commodity prices and farm profitability. Using correlated farm commodity and input prices from the past nine years, farm profitability was calculated for a range of farm types in southwest Victoria under low, average and high rainfall scenarios. Fourteen representative farms were examined that included production of Merino fine wool, prime lamb, beef cattle, milk, wheat and canola. This paper compares and contrasts the spread of profitability of these farms against...

Autores: Hancock,   Wayne M.; Harrison,   Jennifer L.; O'Brian,   Dennis T.
The genetically modified INGARD™ cotton seed was released in Australia in 1996 and was greeted with high expectations and enthusiasm within the cotton industry. INGARD™ cotton seed contains the Cry1A(c) gene from the soil bacteria Bacillus thuringiensis var kurstaki for the biological control of Helicoverpa armigera and H. punctigera moth larvae in cotton. These are the most serious insect pests of cotton and account for the majority of insecticides applied to cotton in Australia. Significant environmental and economic benefits were claimed by the manufacturer (Monsanto) at the time of release through the reduction in pesticide use and from a less complex production management system. Grower attitudes and perceptions relating to INGARD™ were followed over...

Three facts about marijuana prices
Provedor de dados: 31
Autores: Clements,   Kenneth W.
Australians are among the largest consumers of marijuana in the world, and estimates show that their expenditure on marijuana is approximately twice that on wine. In the present paper, the evolution of Australian marijuana prices over the last decade is analysed, and a decline in real terms by almost 40 per cent is shown. This decline is far above that experienced by most agricultural products. Why has this occurred and what are the implications? One possible reason is the adoption of hydroponic growing techniques that have enhanced productivity and lowered costs and prices. Another reason is that laws have become softer and penalties reduced. Patterns in prices are found that divide the country into three broad regions: (i) Sydney, where prices are...

DISTRIBUTED LAGS AND BARLEY ACREAGE RESPONSE ANALYSIS
Provedor de dados: 31
Autores: Anderson,   Kym.
The need to incorporate production response lags in agricultural supply models is established, and two such lags are considered: the familiar adaptive expectations geometric lag, and a more general polynomial lag. These distributed lag supply response models are applied to Australian barley data for the period 1946-47 to 1968-69. A number of statistical problems associated with the adaptive expectations model are discussed, and in particular it is concluded that lags both in the formation of price expectations and in acreage adjustment should be considered when using geometric lag models. While the polynomial lag model does not provide useful results in the present study, its simplicity and flexibility suggest it may be useful in other studies requiring...

INCORPORATING THE 1990 FARM BILL INTO FARM-LEVEL DECISION MODELS: AN APPLICATION TO COTTON FARMS
Provedor de dados: 31
Autores: Duffy,   Patricia A.; Cain,   Danny L.; Young,   George J.
A five-year, 0.1, mixed integer programming model was developed to analyze the effects of 1990 Farm Bill legislation on the crop-mix decisions made on cotton farms.  Results showed that, when compared to the 1985 Farm Bill, the 1990 Farm Bill can result in higher whole-farm income despite new "triple base" provisions limiting payment acres.  The increase in income results from elimination of limited cross-compliance provisions and the change to a three-year base calculation.  The model was also used to assess the likely impact of possible changes in the current legislation.

Autores: Grimm,   Sadi S.; Paris,   Quirino; Williams,   William A.
The century-old “law of the minimum” proposed by von Liebig was tested using five independent sets of crop response data on wheat, corn, cotton, silage, and sugar beets. The rival models were polynomial functions reported in the literature as the most suitable models for interpreting those data. Overall, the von Liebig model performed very well. While the nonnested hypothesis test was inconclusive with regard to silage and sugar beets, the von Liebig model rejected the polynomial specifications for wheat, corn and cotton.

A Comparison of the Great Mississippi River Floods of 1993 and 2011: Implications for Crop Insurance and Reinsurance
Provedor de dados: 31
Autores: Vergara,   Oscar.
The flooding situation in 2011 is similar in nature to the Great Mississippi Flood of 1993, but different in the particulars. First, the timing of the flood within the growing season is different. Second, the two floods occurred in different regions, with the 1993 flood affecting a portion of the Corn Belt and the 2011 flood affecting a region farther south. While floodwaters have inundated several million acres of cropland in 2011, yield losses from delayed planting are expected to be limited. Furthermore, the affected states from the current flood are primarily Group 2 states under the current SRA, which are provided with greater reinsurance protection by the government than the Group 1 states.

A Reexamination of the U.S. Export Demand for Soybeans and Soybean Products
Provedor de dados: 31
Autores: Uri,   Noel D.; Hyberg,   Bengt.
This paper addresses the question of whether the export demand for soybeans and soybean products changed structurally over the 1950 to 1992 period as the U.S. agricultural sector became more integrated with the rest of the world economy. The results suggest that export demands were stable for soybeans, soybean meal and soybean oil over the sample period. Moreover, it is possible to infer conclusively that the long-run soybean and soybean product export price elasticities were in the elastic range. The implications include that for each one percent reduction in the price of soybeans, soybean meal and/or soybean oil brought about through a government program, exports increased by more than one percent, leading to a reduction in the variability of soybean and...

Economic Impacts of the U.S. Soybean Aphid Infestation: A Multi-Regional Competitive Dynamic Analysis
Provedor de dados: 31
Autores: Kim,   C.S.; Schaible,   Glenn D.; Garrett,   Lynn; Lubowski,   Ruben N.; Lee,   Donna J.
We estimated the economic benefits resulting from controlling soybean aphid infestation by using a multi-regional competitive dynamic equilibrium model. Results indicate that the reduction of soybean production resulting from a soybean aphid infestation is largely absorbed by reducing soybean exports, due to the higher price elasticity of export demand compared to domestic demand. Producer benefits resulting from controlling soybean aphids would increase by between $949 million and $1.623 billion in ten years under various scenarios. Results also suggest that it is economically more efficient to control soybean aphids when the rate of intrinsic growth is relatively lower, the supply price elasticity of soybean acreage is relatively more elastic, and...

EFFECTS OF RISK, DISEASE, AND NITROGEN SOURCE ON OPTIMAL NITROGEN FERTILIZATION RATES IN WINTER WHEAT PRODUCTION
Provedor de dados: 31
Autores: Howard,   Donald D.; English,   Burton C.; Larson,   James A.; Roberts,   Roland K.; Walters,   Jeremy T.
Interactions among nitrogen (N) fertilization rate, N source, and disease severity can affect mean yield and yield variance in conservation tillage wheat production.  A Just-Pope model was used to evaluate the effects of N rate, N source, and disease on the spring N-fertilization decision.  Ammonium nitrate (AN) was the utility-maximizing N source regardless of risk preferences.  The net-return-maximizing AN rate was 92 lb N/acre, providing $0.52/acre higher net returns than the best alternative N source (urea).  If a farmer could anticipate a higher than average Take-All infection, the difference in optimal net-returns between AN and urea would increase to $35.11/acre.

ECONOMICS OF TRADE-OFF BETWEEN UREA NITROGEN AND POULTRY LITTER FOR RICE PRODUCTION
Provedor de dados: 31
Autores: Govindasamy,   Ramu; Cochran,   Mark J.; Miller,   David M.; Norman,   Richard J.
This paper identifies optimal combinations of nitrogen in the form of urea, fresh litter and composted litter for rice production.  Traditional cost minimization techniques using data from experimental results conducted at three sites in Arkansas during 1991 have been employed.  Comparisons between different scenarios indicate that the trade-off between the use of poultry litter and urea nitrogen depends on such factors as soil fertility, the yield response to litter application and the relative prices of nitrogen and litter.  The use of litter is more economical at high target yields than at low target yields.

Banana policy: a European perspective
Provedor de dados: 31
Autores: Tangermann,   Stefan.
European Union banana policies do not make economic sense, and hence criticism of these policies is justified. Some facts should, though, be remembered. If the EU had chosen free trade in bananas when the Single Market was established, certain producers both inside and outside the EU would have lost income, and it proved politically impossible to choose direct financial compensation. Also, the quantitative implications of the new EU banana regime may be less than sometimes assumed, as trade has not been reduced very much. The WTO's role is not to judge the economic merits of these policies, but their legal justification.

Local and Regional Food Aid Procurement in Zambia
Provedor de dados: 31
Autores: Haggblade,   Steven; Tschirley,   David L.
By law, US food aid relies on commodity procurement in the US. A powerful political coalition of US farm groups, shippers and relief agencies vigorously supports these in-kind food aid donation. As an alternative, local procurement of food aid, in Africa, has attracted growing interest because of its potential to reduce landed costs and speed delivery times. For this reason, many food aid donors, other than the US, have switched to local and regional procurement of food aid commodities. This paper reviews experience with local and regional food aid procurement in Zambia. The study focuses primarily on experience of the World Food Programme (WFP), the agency with the most extensive experience conducting local and regional procurement in Africa. WFP’s...

ARE CROP YIELDS NORMALLY DISTRIBUTED?
Provedor de dados: 31
Autores: Ramirez,   Octavio A.; Misra,   Sukant K.; Field,   James E.
This paper revisits the issue of crop yield distributions using improved model specifications, estimation and testing procedures that address the methodological concerns raised in recent literature that could have invalidated previous conclusions of yield non-normality. It shows beyond reasonable doubt that some crop yield distributions are non-normal, kurtotic and right or left skewed, depending on the circumstances. A procedure to jointly estimate non-normal farm- and aggregate-level yield distributions with similar means but different variances is illustrated, and the consequences of incorrectly assuming yield normality are explored.

The Adoption of Water Conservation and Intensification Technologies and Farm Income: A Propensity Score Analysis for Rice Farmers in Northern Ghana
Provedor de dados: 31
Autores: Faltermeier,   Liane; Abdulai,   Awudu.
This study uses cross-sectional data of 342 small-scale lowland rice farmers in Northern Region of Ghana to analyze the impact of the adoption decision of bund construction and seed dibbling on net returns, input demand and output supply. Matching was conducted based on Mahalanobis distance combined with propensity score. Balancing tests by checking the mean standardized absolute bias in the matched sample were conducted as well as sensitivity analysis to check for hidden bias due to unobservable selection. The empirical results of impact assessment using propensity score matching controlling for self-selection bias suggest that input demand is significantly higher for adopters of bunds, but not statistically different for adopters and non-adopters of...

A MATHEMATICAL PROGRAMMING MODEL FOR VEGETABLE ROTATIONS
Provedor de dados: 31
Autores: Musser,   Wesley N.; Alexander,   Vickie J.; Tew,   Bernard V.; Smittle,   Doyle A.
Rotations have historically been used to alleviate pest problems in crop production.  This paper considers methods of modeling rotations in linear programming models for Southeastern vegetable production.  In such models, entering each possible crop rotation as a separate activity can be burdensome because of the large numbers of possible rotational alternatives.  Conventional methodology for double crop rotations reduces the number of activities but must be adapted to accommodate triple crop rotational requirements in vegetable production.  This paper demonstrates these methods both for a simple example and an empirical problem with numerous rotation alternatives.  While the methods presented in this paper may have computational disadvantages compared to...

HOW COMPETITIVE IS THE WORLD WHEAT MARKET?
Provedor de dados: 31
Autores: Carter,   Colin A.; MacLaren,   Donald; Yilmaz,   Alper.
Japan is one of the largest importers of wheat in the world, with imports originating from three countries, Australia, Canada, and the United States.  Australia, Canada, and Japan all use a government single-desk agency to control wheat trade.  Many previous studies on competition in the world grain trade have argued the market is imperfectly competitive, and they often point to the Japanese market. We study the Japanese wheat import market for this reason, but find no compelling evidence of imperfect competition.

Potential Impacts of Golden Rice on Public Health in India
Provedor de dados: 31
Autores: Stein,   Alexander J.; Sachdev,   H.P.S.; Qaim,   Matin.
Vitamin A deficiency (VAD) affects millions of people world-wide, causing serious health problems. Golden Rice (GR), which has been genetically engineered to produce beta-carotene, is being proposed as a remedy. While this new technology has aroused controversial debates, its nutritional impact and cost-effectiveness remain unclear. We determine the current burden of VAD in India from a public health perspective,and simulate the potential alleviating impact of GR using representative household food consumption data. Given broad public support, GR could more than halve the overall burden of VAD. Juxtaposing health benefits and overall costs suggests that GR is very costeffective.

Projecting Livestock Numbers
Provedor de dados: 31
Autores: Forbes,   Rod; Gardiner,   Peter.
The Ministry of Agriculture and Forestry (MAF) undertakes forecasts and projections of livestock numbers as part of the twice yearly contribution to The Treasury’s economic and fiscal updates. MAF’s Pastoral Supply Response Model (PSRM) was recently re-developed and used for the first time in the Budget Economic and Fiscal Update round of 2004. The PSRM projects annual inventory numbers as at 30 June, births and livestock numbers for slaughter. The paper discusses the PSRM, the post-model adjustments process, and the feed through to a simplistic assessment of land use changes within pasture areas.

Comparing Accuracy and Costs of Revealed and Stated Preferences: The Case of Consumer Acceptance of Yellow Maize in East Africa
Provedor de dados: 31
Autores: Kimenju,   Simon Chege; De Groote,   Hugo; Morawetz,   Ulrich B.
For quite a while, stated preferences have been a major tool to measure consumer preferences for new products and services. Revealed preference methods, in particular experimental economics, have gained popularity recently because they have been shown to be more incentive compatible, and therefore more accurate. However, this advantage comes at the expense of higher survey costs. In the developing countries with limited funding for research, it is important to determine whether the extra cost can be justified by the extra gain in accuracy. A survey of 100 farmers was carried out in Western Kenya to determine consumer preference for yellow maize using the contingent valuation, choice experiments and experimental auction methods. Experimental auctions...

IMPACTS OF THE ADOPTION OF GENETICALLY ENGINEERED CROPS ON FARM FINANCIAL PERFORMANCE
Provedor de dados: 31
Autores: McBride,   William D.; El-Osta,   Hisham S.
The rapid adoption of genetically engineered (GE) crops by U.S. farmers suggests that these technologies have been perceived to improve farm financial performance.  This study develops and applies an econometric model to data from corn and soybean producers in order to evaluate the financial impacts of the adoption of GE crops.  Results indicate that the adoption of GE crops has had a limited impact on financial performance that varies by crop, type of technology, type of farm, and region of the nation.  Factors other than the financial impacts appear to be important reasons for the rapid adoption of GE crops.

UK SUGAR BEET FARM PRODUCTIVITY UNDER DIFFERENT REFORM SCENARIOS: A FARM LEVEL ANALYSIS
Provedor de dados: 31
Autores: Renwick,   Alan W.; Revoredo-Giha,   Cesar; Reader,   Mark A.
The purpose of this paper is to study the effect that the imminent reform in the European Union (EU) sugar regime may have on farm productivity in the United Kingdom (UK).  We perform the analysis on a sample of sugar beet farms representative of all the UK sugar beet regions. To estimate the changes in productivity, we estimate a multi-output cost function representing the cropping part of the farm, which is the component that would be mostly affected by the sugar beet reform. We use this cost function to compute the new allocation of outputs and inputs after the changes in the sugar beet quota and price support. This are subsequently used to compute measures of total factor productivity. Our results show slight decreases in the productivity at the...

FACTORS AFFECTING DEMAND AND SUPPLY OF RICE IN SIERRA LEONE
Provedor de dados: 31
Autores: Kargbo,   Alimami M.
Sierra Leone, like most developing  countries is primarily agricultural, with about 75 percent of its population getting its living from farming.  The main characteristic of its farming is the large number of small holdings-averaging about two hectares per farm.  Most of these farms are fragmented.  Large-scale farming is a fairly recent development and the few large farms are either government or quasi-government institutions, confined to crops that require expensive machinery and timely processing.  In the country's search for new sources of economic expansion, agriculture assumed first priority.  This was due, in part, to the fact that a large percentage of the population derived its living from agriculture.  In addition, the development of agriculture...

Market and Welfare Effects of Mandatory Country-of-Origin Labeling in the US Specialty Crops Sector
Provedor de dados: 31
Autores: Plastina,   Alejandro S.; Giannakas,   Konstantinos; Pick,   Daniel H.
This study provides a new framework of analysis of the market and welfare effects of mandatory country of origin labeling (MCOOL) for fruits and vegetables that accounts for heterogeneous consumer preferences for domestic products, differences in producer agronomic characteristics, and retailer market power when buying and selling these products. The market and welfare effects of MCOOL are shown to be case-specific and dependent on the labeling costs at the farm and retail levels, the strength of consumer preference for domestic products, the market power of retailers, the marketing margin along the supply chain, and the relative costs of imported and domestic products. Simulation results for the US markets of apples and tomatoes indicate that for the...

Fusarium Head Blight (FHB), commonly known as scab, has been a severe problem for wheat and barley producers since 1993.  This study provides an update of economic losses suffered by wheat and barley producers in scab-affected regions in the United States.  Emphasis is placed on estimating direct and secondary economic impacts of yield and price losses suffered by wheat and barley producers from 1998 to 2000.   Nine states are included in the analysis for three wheat classes.  Three of the nine states were also used for the analysis of malting and feed barley.  The cumulative direct economic losses from FHB in hard red spring (HRS) wheat, soft red winter (SRW) wheat, durum wheat, and barley is estimated at $870 million from 1998 through 2000.  The combined...

Combining revealed and stated preference methods to assess the private value of agrobiodiversity in Hungarian home gardens
Provedor de dados: 31
Autores: Birol,   Ekin; Kontoleon,   Andreas; Smale,   Melinda.
Hungarian home gardens are small-scale farms managed by farm households using traditional management practices and family labor. They generate private benefits for farmers by enhancing diet quality and providing food when costs of transacting in local markets are high. Home gardens also generate public benefits for society by supporting long-term productivity advances in agriculture. In this paper, we estimate the private value to farmers of agrobiodiversity in home gardens. Building on the approach presented in EPTD Discussion Paper 117 (2004), we combine a stated preference approach (a choice experiment model) and a revealed preference approach (a discrete-choice, farm household model). Both models are based on random utility theory. To combine the...

Autores: Frisvold,   George B.; Hurley,   Terrance M.; Mitchell,   Paul D.
This study examined adoption of ten best management practices (BMPs) to control weed resistance to herbicides. Using data from a survey of 1,205 U.S. cotton, corn, and soybean growers, count data models were estimated to explain the total number of practices frequently adopted. Ordered probit regressions were used to explain the frequency of individual BMP adoption. Growers practicing a greater number of BMPs frequently (a) had more education, but less farming experience; (b) grew cotton, (c) expected higher yields relative to the county average; and (d) farmed in counties with a lower coefficient of variation (CV) for yield of their primary crop. Yield expectations and variability were significant predictors of the frequency of adoption of individual...

Cross-Commodity Analysis of China's Grain Sector: Sources of Growth and Supply Response
Provedor de dados: 31
Autores: Colby,   Hunter; Diao,   Xinshen; Somwaru,   Agapi.
We investigate sources of output growth and supply response in rice, wheat, corn, and soybeans, the four most important crops in China's grain sector, during 1978-97. Using a growth accounting methodology, we found large total factor productivity (TFP) contributions to growth in grain production immediately following China's rural economic reform (1978-85). In 1995-97, the TFP contribution dropped to only 16 percent of growth in grain production, as greater use of inputs increasingly drove growth. In the supply response analysis, the results of the econometrically estimated restricted profit function confirm a joint and nonseparable multiproduct technology for China's grain sector. Complementarity prevails in the grain sector among different outputs and...

This study investigates firm level technical efficiency of production and its determinants in a sample of 137 olive oil manufacturing firms in Tunisia using a stochastic frontier production model applied to cross-section data. Results indicate that technical efficiency of production in the sample of olive oil manufacturing firms investigated ranges from a minimum of 47.1% to a maximum 99.5% with an average technical efficiency estimate of 86.5%. This implies olive oil manufacturing firms in Tunisia can increase their production on average by 13.5% through more efficient use of technology and production inputs. The fact that 93 firms represented more than 64.4% of the sample hit more than 80% of technical efficiency score implies the efficacy of...

Buyer Market Power and Vertically Differentiated Retailers
Provedor de dados: 31
Autores: Wang,   Shinn-Shyr; Rojas,   Christian; Lavoie,   Nathalie.
We consider a model of vertical competition where downstream firms (retailers) purchase an upstream input from a monopolist and are able to differentiate from each other in terms of quality. Our primary focus is to study the effects of introducing a large retailer, such as a Wal-Mart Supercenter, that is able to lower wholesale prices (i.e. buyer market power). We obtain two main results. First, the store with no buyer market power responds to the presence of the large retailer by increasing its quality, a finding that is consistent with recent efforts by traditional retailers to enhance shoppers’ buying experience (i.e. quality). Second, the presence of a large retailer causes consumer welfare to increase. There are, however, two reasons for the increase...

This article reports the results of an industry-level study that seeks to identify empirical regularities between firm strategy, management style, organisational structure and performance in the Spanish fresh fruit and vegetable (fresh produce) industry using strategic group analysis. Groups were formed from key dimensions reflecting firms' strategic orientations. Performance levels did not differ systematically between strategic groups, but performance was found to be influenced by the alignment between entrepreneurial culture and organisational structure. A move towards greater flexibility and/or adopting an entrepreneurial style are both likely to contribute to an improvement in the overall performance of the firm.

Groundwater use is rapidly increasing in Sri Lanka, bringing several benefits to small farmers—by allowing them to grow more crops, minimize the impact of droughts, and profit from selling high-value produce. But how can this be sustained? Lessons learned from other countries with longer histories of groundwater use can help policymakers, planners, and development organizations avoid the pitfalls and dangers of indiscriminate use, and capture the benefits that groundwater can bring.

This article describes the relative size of the green industry within the U.S. economy and how it is linked to supporting industries through the volume of transactions and economic impact multipliers. This analysis was based on IMPLAN, an input-output model developed by the U.S. Forest Service. In terms of 1990 employment, the green industry was the second leading employer in United States production agriculture. In terms of output, the greenhouse and products sector ranked sixth within production agriculture, behind cattle, other livestock, grains, other crops and oil bearing crops.

The Almond Board of California proposed to require that all almonds shipped from California handlers be treated to achieve a 4-log reduction in the pathogen that leads to salmonellosis. The Assurance program is expected to add several million dollars to transactions costs in the almond marketing system. There is a wide range in these cost estimates, mainly because of the difficulty in predicting how many firms will be interested in applying for the program.

Autores: Skees,   Jerry R.; Hazell,   Peter B.R.; Miranda,   Mario J.
Natural disasters can be extremely disruptive to farmers and to others whose incomes depend on a successful crop. Society can gain from more efficient sharing of crop and natural disaster risks. However, the costs associated with traditional agricultural risk programs have historically exceeded the gains from improved risk sharing. This paper explores government intervention in agricultural risk markets and discusses new approaches to risk sharing with limited government involvement. In particular, we build the case for introducing negotiable state-contingent contracts settled on area crop yield estimates or locally appropriate weather indices. These instruments could replace traditional crop insurance at a lower cost to government while meeting the risk...

This paper examines the impact of direct income payments on productive efficiency of Korean rice farms, using farm-level cross sectional data in 2006. For representation of efficiency and its determinants, this paper uses a model that estimates the deviations of farms from a translog distance function and the determinants of these deviations. This paper especially estimates a stochastic frontier production function to explain deviations from best-practice productivity with a two-part error term including statistical noise from measurement error and technical inefficiency arising from farms not reaching the production frontier boundary. The empirical evidence finds that farms that get a higher share of direct payments in farm revenue are less efficient than...

The impact of the EU Water Framework Directive on irrigated agriculture in Italy: the case of the North-East fruit district
Provedor de dados: 31
Autores: Bazzani,   Guido Maria; di Pasquale,   S.; Gallerani,   Vittorio; Morganti,   S.; Raggi,   Meri; Viaggi,   Davide.
The objective of the paper is to evaluate the sustainability of irrigated agriculture under Water Framework Directive (60/2000) and Agenda 2000. The methodology relies on scenario analysis combined to farm level multicriteria mathematical programming. The methodology is applied to the case study of fruit farming in Northern Italy. The research shows that water pricing can improve irrigation efficiency, but the impact of water policy is strongly affected by agricultural policy scenarios. In order to make water policies more socially sound, it is necessary to consider a broader range of impacts and to provide a higher co-ordination between policy goals.

CONSTRAINTS FOR COLLECTIVE ACTION IN BULGARIA'S IRRIGATION SECTOR
Provedor de dados: 31
Autores: Theesfeld,   Insa.
Water for irrigation and irrigation infrastructure are both common pool resources, due to their low excludability and high rivalry. The wellknown common pool resource dilemma is often the consequence. Collective action may be a way how societies can overcome this dilemma. First results from a three-month empirical field study in Bulgaria are presented trying to explain how actor groups characteristics, such as lack of trust between community members and effective institutional settings at the local level, such as information asymmetry, limited sanctioning and enforcement mechanisms and almost no monitoring mechanisms provide conditions under which opportunistic behaviour dominates. The effective rules-in-use in local communities are presented. The simplest...

QUANTIFYING THE HETEROGENEITY OF ABATEMENT COSTS UNDER CLIMATIC AND ENVIRONMENTAL REGULATION CHANGES: AN INTEGRATED MODELLING APPROACH
Provedor de dados: 31
Autores: Leclere,   David; Jayet,   Pierre-Alain; Zakharov,   Paul; de Noblet-Ducoudre,   Nathalie.
We present here preliminary results of an integrated modelling approach combining a crop model (STICS) and an economic model (AROPAj) of European agricultural supply. This modelling framework is designed to perform quantitative analysis, regarding climate change impacts on agriculture and more generally the interactions between soils, land use, agriculture and climate integrating physical and economical elements (data, process, models). It explicitly integrates an agricultural diversity dimension with regards to economic set of choices and soil climate spatial variability. First results are given in term of quantitative analysis combining optimal land allocation (economic optimality) and “dose-response” functions related to a large set of crops in Europe,...

Evidence on trends in the single factoral terms of trade in African agricultural commodity production
Provedor de dados: 31
Autores: Fleming,   Euan M.; Fleming,   Pauline.
The ability of African countries to achieve sustained improvements in agricultural incomes depends on their ability to generate total factor productivity (TFP) change in their agricultural sectors and adjust to movements in agricultural output and input prices. The single factoral terms of trade index measures these changes, calculated as changes in the product of TFP and the agricultural terms of trade. Estimates of the single factoral terms of trade index for the selected commodities over the period 1970-2002 are reported and discussed for 33 African countries for which data sets are available. The index is estimated for producers of coffee, cocoa, copra, palm kernel oil, coconut oil, palm oil, rice, cotton and sugar using annual agricultural sector...

Empirical Confidence Intervals for WASDE Forecasts of Corn, Soybean and Wheat Prices

Autores: Isengildina,   Olga; Irwin,   Scott H.; Good,   Darrel L.
This study suggests that confidence intervals for WASDE forecasts of corn, soybean, and wheat prices may be improved if they are estimated using an empirical approach.  Empirical confidence intervals are calculated following Williams and Goodman's (1971) method and use historical forecast errors to estimate forecast error distributions which is then used to predict confidence limits for future forecast errors.  Three procedures for empirical distribution estimation are compared: 1) histogram, 2) changing distribution, 3) fixed distribution.  The results suggest that the fixed distribution approach using logistic distribution provided accurate confidence intervals for WASDE corn, soybean, and wheat price forecasts.

Forecasting World Crop Yields as Probability Distributions
Provedor de dados: 31
Autores: Ferris,   John N.
Traditionally, agricultural forecasts, whether for the coming year or several years into the future, have been based on assumptions of normal weather and trend crop yields.  That weather is seldom normal and that yields seldom fit trends are well recognized.  However, relatively little attention has been given to projecting crop yields stochastically even though computer capacity and software programs are available to do so.  One reason is that the task is more challenging than to assign standard deviations to various crop yields and simulate normal distributions using random number generators.  For one, deviations of crop yields from trends may be correlated especially if the locations of the crops overlap such as is the case with US corn and soybeans....

We implement stochastic frontier analysis techniques to show the effects of information technology use on firm efficiency.  Results from a sample of 1,865 U.S. cash grain farms reveals that information technology use within the farm business moved farms significantly towards the efficiency frontier.  Also moving farms towards the  efficiency frontier were the use of written long-term plans, advanced input acquisition strategies, and increased farm labor hours relative to total labor hours.  In contrast, an increase in the debt to asset ratio was associated with movements away from the efficiency frontier.

Trait Stacking, Licensing, and Seed Firm Acquisitions on Genetically Modified Grains: A Strategic Analysis
Provedor de dados: 31
Autores: Wilson,   William W.; Huso,   Scott R.
Commercialization of genetically modified (GM) traits leads to interesting strategic questions for agbiotechnology and seed firms.  The purpose of the study is to evaluate equilibrium strategies of agbiotechnology and seed firms regarding commercialization of GM traits.  Two game theory models were developed to examine equilibrium strategies.  In the first, both agbiotechnology firms have commercialization strategies of licensing or not.  In the second, the agbiotechnology firm also has the strategic option to purchase a seed form as a commercialization strategy.  Results indicate that the equilibrium strategy would be for each of the agbiotechnology firms to license their traits, and the seed firm would release a stacked trait.  However, order of play...

Autores: Perry,   Gregory M.; Rister,   M. Edward; Richardson,   James W.; Grant,   Warren R.
Whole farm simulation analysis and econometric techniques are employed in an analysis of crop rotations and tenure arrangement strategies. The FLIPSIM model is used to analyze a representative Texas Upper Gulf Coast rice and soybean farm. Probit analysis is then used to determine the impact of net cash farm income, land tenure, and crop rotation on probability of survival. Results suggest that, although the simulation model is useful in providing information on the effect at the farm level of following the different strategies, probit results provide greater understanding into the returns and risk inherent to each strategy.

ASSESSING THE COMPETITIVENESS OF INDIAN COTTON PRODUCTION: A POLICY ANALYSIS MATRIX APPROACH
Provedor de dados: 31
Autores: Mohanty,   Samarendu; Fang,   Cheng; Chaudhary,   Jagadanand.
This paper uses a modified policy analysis matrix (PAM) approach to assess the efficiency of cotton production in five major producing states in India. The results indicate that cotton is not efficiently produced in the second-largest cotton-producing state in the country. Without government interventions in this state, it is likely that acreage will move away from cotton to more profitable crops such as sugarcane and groundnut. In addition, we conclude that cotton is not the most efficiently produced crop in the other four states; however, there is at least one crop in each state that is less efficiently produced than cotton. These findings suggest that Indian policies directed at maintaining the availability of cheap cotton for the handloom and textile...

The analysis is based on detailed data on final consumption and prices at both shipper and consumer levels for two types of tomatoes in France. The structural model is composed of a system of demand equation and supply equation. Supply equation includes a term that represents the market power of the retail sector. We use different models of demand in order to test the robustness of our results. We show that i) elasticity of demand varies during the year ii) the retail sector exercise only a "moderate" market power iii) the estimated...

THE MICROECONOMIC IMPACT OF IPM ADOPTION: THEORY AND APPLICATION
Provedor de dados: 31
Autores: Fernandez-Cornejo,   Jorge.
This paper develops a methodology to calculate the impact of integrated pest management (IPM) on pesticide use, yields, and farm profits.  The methodology is applied to the IPM adoption among fresh market tomato producers in eight states.  The method is of general applicability.  It accounts for self-selectivity and simultaneity, and the pesticide demand and yield equations are theoretically consistent with a profit function.  The results support the notion that fresh market tomato growers who adopt IPM for insects and diseases apply significantly less insecticides and fungicides, respectively, than do those who do not adopt IPM; IPM adoption has an insignificant effect on yields and a small effect on profits.

While the population of the world is continually growing, there are doubts that the food supply will be sufficient to keep pace.  Although 14% of the world is undernourished today, an exponentially increasing population could be catastrophic if agricultural production lags too far behind.  This paper attempts to forecast agricultural yield given the recent advent of genetically modified crops as a means to see whether this technology has the potential to help supply the world with food in the future.  Through regression, a model was developed to make predictions of corn yields as a case study on how biotechnology might affect future agricultural production.

The purpose of this report is to improve understanding of USDA crop forecasting methods, performance and market impact.  A review of USDA's forecasting procedures and methodology confirmed the objectivity and consistency of the forecasting process over time.  No changes in methodology occurred in 2004.  Month-to-month changes in corn and soybean production forecasts from 1970 through 2004 indicated little difference in magnitude and direction of monthly changes over time.  USDA production forecast errors were largest in August and smaller in subsequent forecasts.  There appeared to be no trend in the size or direction of forecast errors over time.  On average, USDA corn production forecasts were more accurate than private market forecasts over 1970-2004,...

The paper discusses a methodology for design and pricing of index insurance contracts for crop production. The methodology heavily relies on establishing a relationship between the index and yields in order to evaluate the contract performance in hedging farmers' risk. However, analysis of yield/rainfall data series for Iowa corn and Kansas wheat fail to produce a reliable and meaningful relationship which can be used uniformly across several counties and/or crop producing districts. Further research is needed as to applicability of rainfall insurance to specific crop/region combinations.

Autores: Price,   Gregory K.; Lin,   William W.; Falck-Zepeda,   Jose Benjamin; Fernandez-Cornejo,   Jorge.
This study estimates the total benefit arising from the adoption of agricultural biotechnology in one year (1997) and its distribution among key stakeholders along the production and marketing chain. The analysis focuses on three biotech crops: herbicide-tolerant soybeans, insect-resistant (Bt) cotton, and herbicide-tolerant cotton. Adoption of these crops resulted in estimated market benefits of $212.5-$300.7 million for Bt cotton, $231.8 million for herbicide-tolerant cotton, and $307.5 million for herbicide-tolerant soybeans. These benefits accounted for small shares of crop production value, ranging from 2 percent to 5 percent. U.S. farmers captured a much larger share (about a third) of the benefits for Bt cotton than with herbicide-tolerant soybeans...

Autores: Siregar,   Masdjidin; Sugino,   Tomohide.
Since the Kyoto Protocol came into effect in 2005, more attention has been paid to the development of biomass resource use. The tropical Asian countries have large potential for biomass production. In order to reduce imported fuel, the Government of Indonesia is attempting to find alternative renewable energy, particularly in the form of biofuel. The report presents the prospects for biofuel projects and the possible impacts on rural society based on a case study of bioethanol production from cassava. In this study, East Lampung and North Lampung districts have been chosen for case study

Estimating the Spatial Distribution of Groundwater Demand In the Texas High Plains
Provedor de dados: 31
Autores: Zhao,   Shiliang; Wang,   Chenggang; Bordovsky,   James P.; Sheng,   Zhuping; Gastelum,   Jesus R.
Developing groundwater management plans requires a good understanding of the interdependence of groundwater hydrology and producer water use behavior. While state-of-the-art groundwater models require water demand data at highly disaggregated levels, the lack of producer water use data has held up the progress to meet that need. This paper proposes an econometric framework that links county-level crop acreage data to well-level hydrologic data to produce heterogeneous patterns of crop choice and irrigation practices within a county. Together with agronomic data on irrigation water requirements of various crops and irrigation practices, this model permits estimation of the water demand distribution within a county. We apply this model to a panel of 16...

Autores: Urfi,   Peter; Kormosne-Koch,   Krisztina.
Az ökológiai gazdálkodás költség-jövedelem viszonyait a hagyományos termeléssel összehasonlítva, modellszámítások alapján vizsgáltuk. A modellépítéshez szükséges adatokat Hortobágy térségében működő egyéni gazdálkodók körében gyűjtöttünk. Az egy hektárra jutó költségek összegében a két gazdálkodási mód között jelentőseltérések nem voltak, a költségek szerkezete azonban markáns különbségeket mutatott, amely a technológiák eltéréseivel magyarázható. Az ökológiai növénytermelésben a hozamok jellemzően alacsonyabbak voltak, az önköltség és az értékesítési árak viszont magasabbak. Egyik termelési mód sem bizonyult életképesnek támogatások nélkül, a bruttó jövedelem különbségeit azonban nem a támogatások, hanem elsősorban az eltérő hozamok és értékesítési árak...

PLANT PESTICIDE ECONOMICS WITH SPECIAL REFERENCE TO COTTON INSECTICIDES
Provedor de dados: 31
Autores: Longworth,   John W.; Rudd,   Don.
The energy crisis and the current world food situation have both drawn attention to the importance of off-farm inputs in high-technology agricultural systems. Plant pesticides are one of the most important of these off-farm inputs. The correct use of chemical pesticides requires a high level of managerial competence since the issues involved are extremely complex. The development of an integrated approach to the management of plant pests offers an alternative to the increasingly expensive chemical control techniques. Cotton production illustrates both the complexities of the management involved in plant pest control and the feasibility of developing integrated control strategies. Plant pesticides, especially insecticides, also create externalities. The...

STUDY ON THE ECONOMIC EFFECT OF PRODUCTION FREE FROM CHEMICAL USE
Provedor de dados: 31
Autores: Kis,   Sandor.
The assumption, that in case of production different from the conventional one, operational and production risk are increasing in farms, is supported by the calculations. Input/output relations undergo a change in each sector and this may have serious financial outcomes, which would importantly determine profit yielding capacity and efficiency of farming. The statement of Offermann and Nieberg is true of the cost structure, according to which essential cost difference between the two technologies can not be measured. By the aid of the calculation, it was successfully verified – in compliance with the opinion of Wookey – that organic production can be as profitable, as the conventional production or even more so. In contradiction to Bmvel’s data, it can be...

Estimation of Actual and Potential Adoption Rates and Determinants of Improved Rice Variety Among Rice Farmers in Nigeria: The Case of NERICAs
Provedor de dados: 31
Autores: Dontsop Nguezet,   Paul Martin; Diagne,   Aliou; Okoruwa,   Victor O.
The article used the ATE estimation framework to derive consistent semi-parametric estimators of population adoption rates and their determinants of the NERICA (New Rice for Africa) rice varieties in Nigeria. Empirical evidence shows that the observed sample adoption rate does not consistently estimate the population adoption rate even if the sample is random. NERICA awareness was found to be a major constraint to NERICA adoption in Nigeria. Several socioeconomic/demographic characteristics were found to be important determinants of NERICA awareness and adoption. Among those factors are age, gender, major occupation, year of experience and vocational training. In particular, we have found that the NERICA adoption rate in Nigeria would have been up to 76%...

CANADIAN TRANSPORTATION AND GRAIN HANDLING: ISSUES AFFECTING THE NORTH AMERICAN BARLEY SECTOR
Provedor de dados: 31
Autores: Park,   Joon J.; Wilson,   William W.; Johnson,   D. Demcey.
The Canadian grain handling and transportation system has undergone substantial change in recent years, particularly since the elimination of rail subsidies in 1995. Competitive pressures and branch line abandonment have forced many primary elevators to close, while scores of new high-throughput elevators have been constructed across the Prairies. Rationalization of the grain handling system and proposals for further deregulation of rail transportation are driven by the need to improve system efficiency. Policy recommendations of the Estey Report (notably, the elimination of rail rate caps, and 'port buying' by the Canadian Wheat Board) would have important consequences for the grain trade and are contentious issues within Canada. Changes in grain...

Adoption and Impact of Hybrid Wheat in India
Provedor de dados: 31
Autores: Matuschke,   Ira; Qaim,   Matin.
In the light of ongoing debates about the suitability of hybrid seeds for smallholder farmers, this paper analyzes the adoption and impact of hybrid wheat in India. Based on survey data we show that farmers can benefit significantly from the proprietary technology. Neither farm size nor the subsistence level influence the adoption decision, but access to information and credit matters. Moreover, willingness-to-pay analysis reveals that adoption levels would be higher if seed prices were reduced. Given decreasing public support to agricultural research, policies should be targeted at reducing institutional constraints, to ensure that resource-poor farmers are not bypassed by private sector innovations.

Selection of Peach Varieties and the Role of Quality Attributes
Provedor de dados: 31
Autores: Park,   Timothy A.; Florkowski,   Wojciech J.
Timely adoption of new varieties is critical to profitable peach production, and peach quality is a primary factor driving adoption. An adoption model for peach varieties is estimated, incorporating grower evaluations of peach quality. The model identifies the impact of farm characteristics such as the farmer's quality preferences, on-farm agronomic and orchard conditions, as well as geographic effects in Georgia peach-growing regions. The relative impact of the key external and internal peach quality attributes on adoption is assessed. Decisions on new varieties are influenced by the age distribution of the orchard, information which can be used in targeting new varieties to growers.

Grain Contracting Strategies to Induce Delivery and Performance in Volatile Markets
Provedor de dados: 31
Autores: Wilson,   William W.; Dahl,   Bruce L.
One of the impacts of higher prices along with greater volatility in futures and basis is that there is pressure for an escalation in cash contracting for grain. This volatility has resulted in an unprecedented level of contracting with growers in recent years. There is a wide array of cash contracts with varying terms. There is also a growing realization of growers not delivering on contracts, in part due to escalation in postcontract prices. These are evolving as major strategic issues for buyers and the marketing system, particularly as buyers seek to use such contracting strategies as an element of risk mitigation. There are three purposes of this article. First is to provide a broad survey of contract terms used in grain contracting with growers....

MARKETING MECHANISMS TO FACILITATE CO-EXISTENCE OF GM AND NON-GM CROPS
Provedor de dados: 31
Autores: Henry,   Benjamin; Wilson,   William W.; Dahl,   Bruce L.
Development of genetically modified (GM) and specialty crops has had a great impact on the grain handling industry during recent years. Added costs associated with handling these crops have become an important issue for grain handlers. For this study, data were collected from a survey of elevators in the Upper Midwest. The information focused on segregation practices, time requirements, and costs. This study shows the different costs (grading and handling) associated with segregation practices at the grain-handler level. The results revealed that the cost of modifying systems to handle GM is of major importance. A stochastic simulation model of an engineering cost function is developed to analyze costs for segregation and testing using results from the...

State Government support for WA farmers experiencing adverse seasons in 1998 to 2001: A comment
Provedor de dados: 31
Autores: Coyle,   Peter; Mayberry,   Chris.
In response to a series of adverse weather events, in parts of the cereal crop belt from 1998 to 2001, the State and the Commonwealth Governments implemented support measures for farmers in the cereal belt of Western Australia. A critique of the State Government Adverse Seasonal Conditions in the Agricultural Sector (ASCAS) support packages is presented. The schemes are expensive, could adversely affect the normal adjustment process, have subjective boundaries, deliver grants to some multi millionaires, attract a small element of clearly ineligible claimants, and in 2001 the second ASCAS package was provided prior to excellent late winter and spring rains.

A Unified Approach to the Estimation of Demand for Improved Seed in Developing Agriculture
Provedor de dados: 31
Autores: Langyintuo,   Augustine S.; Hamazakaza,   Petan; Nawale,   Edah; Mekuria,   Mulugetta.
This paper proposes a new approach for estimating the demand for seed within a developing country context where only improved seeds are sold but adoption rates for improved varieties low. A farmer views an improved seed firstly as a derived input embodying production attributes and secondly, as a technology embodying consumption characteristics. He therefore jointly decides on its adoption and the quantity of seed required to plant a predetermined area. Drawing on the theory of demand for consumption goods characteristics and production input attributes, this paper specified and estimated non-separable household demand and consumption models using data collected from 300 farm households in Zambia during the 2003/04 crop season. The estimated results...

ANALYSIS OF IMPORT DEMAND FOR U.S. FRESH GRAPES: AN APPLICATION OF THE ROTTERDAM MODEL
Provedor de dados: 31
Autores: Weatherspoon,   Dave D.; Davis,   Christopher G.; Olorunnipa,   Zacch.
The Rotterdam model was used to determine the demand for fresh table grapes in Canada, Japan, and Sweden from 1971-1990.  Results of elastic expenditure elasticities and cross price elasticities indicating that U.S. grapes are considered substitutes for grapes from other countries, suggest that the U.S. grape producers have a competitive edge in these countries.  The trade agreements and trade negotiations with Canada and Japan will assist in making relative prices lower for U.S. grapes, encouraging their consumption.  Lastly, Canada, Japan, and Sweden are all expected to grow in wealth, as well as their demand for fruit, especially grapes.

Smallholder Household Maize Production and Marketing Behavior in Zambia: Implications for Policy
Provedor de dados: 31
Autores: Zulu,   Ballard; Jayne,   Thomas S.; Beaver,   Margaret.
CSO/MACO nationally-representative rural surveys provide important insights on smallholder crop marketing behavior from the 2001 and 2004 harvests. Only about 25 percent of smallholder farmers in Zambia sold maize in both seasons, and about 15-20 percent of smallholders sold fresh horticulture as well as groundnuts, with 11-13 percent selling cassava. From 6-10 percent of farmers produced and sold cotton. Overall, Zambian smallholder agriculture has become more diversified over the past decade, with maize, cassava, groundnuts, cotton, horticultural crops, and animal products all becoming important sources of cash revenue as well as production for home consumption (except, of course, cotton). Importantly in both seasons studied, horticulture crop sales are...

Intellectual Property Rights and Their Impacts in Developing Countries: An Empirical Analysis of Maize Breeding in Mexico
Provedor de dados: 31
Autores: Leger,   Andreanne.
There is little empirical evidence concerning the effects of intellectual property rights (IPR) on a technologically advanced developing country. Complete enumeration of the Mexican maize breeding industry showed that, contrary to the hypothesis that IPR would provide, in a technologically advanced developing country, incentives for R&amp;D and innovation, IPR play no role for the industry in general, but that they are important for certain breeders' categories. The paper presents the theory on IPR and a short background on the Mexican maize breeding industry.

Vertical Integration in Produce Markets: A Colorado Cooperative’s Strategic Response to Change
Provedor de dados: 31
Autores: Hine,   Susan E.; Pritchett,   James G.; Loureiro,   Maria L.; Meyer,   Susan E.
An evolving produce industry has placed vegetable growers in northern Colorado at a competitive disadvantage. The Colorado producers’ strategic response is to form a value-added, cold storage processing cooperative in the hopes of establishing a better position for marketing their vegetables on a year-round basis. This case study discusses the results of both a market demand and processing feasibility study conducted for these vegetable growers.

Is Investment in Agricultural Research a Good Substitute for Price Support in U.S. Cotton?
Provedor de dados: 31
Autores: Pan,   Suwen; Wang,   Changgang; Hudson,   Darren.
This article examines the effects of R&amp;D on cotton yield and relationship between R&amp;D and commodity support programs. The results indicate that yield elasticities with respect to cotton R&amp;D is around 0.2-0.5 based on different regions. It further indicates that R&amp;D increases government expenditures when both commodity programs and R&amp;D funding exist. However, if the future WTO Doha negotiations rules out the possibility of price support programs, increasing R&amp;D funding may provide one of the solutions for farmers to recover their income with 5-6 years lag.

ACCESSING SEED THROUGH SHARECROPPING:  A RISK-SHARING STRATEGY FOR ANDEAN FARMERS
Provedor de dados: 31
Autores: Godtland,   Erin; Sadoulet,   Elisabeth; de Janvry,   Alain; Murgai,   Rinku.
In the Northern Andes, one of the riskiest agriculture climates in the world, farmers use sharecropping to obtain seed, their most costly input.  With survey data from Peru, this paper calculates that the cost of seed, when it is provided though sharecropping, is two times higher than the market price.  We test the hypothesis that risk-averse farmers are willing to pay more to receive seed through sharecropping because the contract provides implicit crop insurance.

Russia’s cereal markets: current trends, changes in net-trade position, and policy implications
Provedor de dados: 31
Autores: Muller,   Marc; Wehrheim,   Peter.
This paper provides an overview of the most recent developments on Russian cereal markets. A review of annual statistics on domestic production, trade, consumption, and storage of cereals reveals that the improvement in Russia’s net trade position cannot only be explained by increased productivity of grain producers. Exhausted storage capacities and lowered real trade costs after the devaluation of the Russian rouble in 1998 seem to have contributed to these developments. A computable general equilibrium model for Russia based on 1999 data was used for analyzing various economic developments and policy changes. The model simulations show that market protection in the short run, when the flexibility of labor and capital is restricted, may benefit Russian...

The breakdown of the planned economy in the Czech Republic induced many changes for the Czech sugar industry. Successful restructuring should foster competitiveness of sugar production and processing. Another target of the sugar sector is its preparation for EU-accession by adjusting to EU market regulations. Consequently, the liberal sugar market policy which was introduced shortly after 1989 was transferred into a system with price and quantity control. Today, this policy differs only in degree from EU market policy. The processes of privatization, restructuring and modernization have been conducted successfully in the nineties. International investors made significant contributions, especially by investing in sugar processing. Despite of a favorable...

Economic possibilities in the integrated wheat production through the agri-environment measures in a Hungarian agricultural enterprise
Provedor de dados: 31
Autores: Nemeth,   Barbara; Fodor,   Attila.
The payment amount of the entry level scheme significantly exceeds the additional costs which arise from abiding by the regulations and with this the financial situation and competitiveness of the viable agricultural enterprises may improve. Based on the pre-calculation in relation to the fortuituos entry into the integrated target scheme it can be concluded that the additional cost determined by the target scheme would only use up just about half of the surplus payment allotted through the integrated target scheme. It is well-worth to make use of the opportunities given by these schemes, because through them the enterprise can obtain a regular, secure and significant income.

Through a survey of scientists from the International Maize and Wheat Improvement Center (CIMMYT) in 2004, this study assessed the extent to which participatory methods had been used by the center, how they were perceived by the scientists, and how participatory research could be applied more effectively by CIMMYT and partners. Results for 19 CIMMYT projects suggest among other things that participatory approaches at the center were largely “functional”—that is, aimed at improving the efficiency and relevance of research—and had in fact added value to the research efforts. The authors suggest that CIMMYT should (1) create a more conducive environment for scientists to share experiences on such approaches and (2) better document their impacts on farmers’...

This paper describes research to create a national database of switchgrass supply as part of the biomass program launched by the Department of Energy. The paper provides an estimate of county level switchgrass yield data for the state of Oklahoma. The estimates are made for the top five most productive and abundant soils for each county in Oklahoma. A simple approach of ratio calculation and estimation is used to predict the switchgrass yield of one soil type by comparing it with the yield of several other crops in another soil type. The data for switchgrass yield for a particular soil type are obtained from the state research experiment stations. The yields for other crops for the top five soils are obtained from the NASS data sources. Switchgrass supply...

Autores: Fadiga,   Mohamadou L.; Mohanty,   Samarendu; Pan,   Suwen.
This study uses a stochastic simulation approach based on a partial equilibrium structural econometric model of the world fiber market to examine the effects of a removal of U.S. cotton programs on the world market. The effects on world cotton prices and African export earnings were analyzed. The results suggest that on average an elimination of U.S. cotton programs would lead to a marginal increase in the world cotton prices thus resulting in minimal gain for cotton exporting countries in Africa.

Autores: Wilson,   William W.; Dahl,   Bruce L.
This study examined moisture specification practices in the United States and for major exporters and assessed impacts of changes to a nil or constant moisture basis on prices and revenue.  These were examined under scenarios where information on moisture in current prices is limited and under a scenario where current prices reflect Full Knowledge of moisture advantages.  Results indicate that changing to a nil moisture basis (which requires a subsequent adjustment in volumes to reflect the subtraction of moisture) would increase reported prices from 42 to 70 c/bu for the wheat classes, while changing to a 12 percent constant moisture basis would have limited impacts on reported prices.  Effects on relative prices/revenue depend on whether knowledge of...

PRICE LINKAGES IN THE INTERNATIONAL WHEAT MARKET
Provedor de dados: 31
Autores: Ghoshray,   Atanu; Lloyd,   Tim A.
This paper brings time series techniques to bear on the relationships between the prices of the principal types of wheat traded internationally.  In all, the relationships between eleven wheat prices (categorised by wheat quality, harvest date and port of despatch) are scrutinised to uncover the structure of the wheat market implicit in the behaviour its prices reveal.  The statistical evidence supports the notion of a highly integrated market that is segmented according to wheat strength-the principal determinant of end-use.  Three segments are identified: a market for 'strong' (bread-making) wheat, another for 'weak' (confectionary products-making) wheat and a third for medium strength wheat suitable for unleavened breads and noodles.  Whilst...

Autores: Gaspar,   P.; Mesias,   F.J.; Escribano Sanchez,   Miguel; Pulido,   F.
The aim of this paper is to model some production variables in extensive livestock farms located in the dehesa ecosystem. We intend to use not only purely economic variables in the construction of the model, but also structural variables in order to identify the characteristics of the farms that have the higher influence. Another objective is to be able to predict these variables at the farm level, using structural variables that are easy to measure. The data used in this work were obtained from a questionnaire survey to the holders/managers of a sample of 69 dehesa farms in Extremadura (SW Spain). The statistical methodology used for the construction of the model was Partial Least Square Regression (PLSR). It can be concluded that the variables relative...

Markets, Institutions, and the Quality of Agricultural Products: Cotton Quality in India
Provedor de dados: 31
Autores: MacDonald,   Stephen; Naik,   Gopal; Landes,   Rip.
The modern global textile industry requires cotton with strong and consistent fibers in order to produce high quality goods at the high speeds necessary to recover capital costs. The introduction of high volume instrument (HVI) measurement of cotton fiber quality has strengthened the link between cotton prices and attributes on world markets. The spread of genetically modified (GMO) cotton in India has driven India to the second ranked producer and exporter of cotton in the world. However, contamination and other quality problems are endemic to Indian cotton. Using a unique data set of Indian cotton prices and quality attributes from 5 Indian states, this study uses hedonic price modeling to demonstrate that the linkages between cotton quality and price...

Food product differentiation leads to significant price variations among the same products, meaning that specific products can be sold in higher prices. An Hedonic Price  analysis  is  adopted  to  investigate  the  influence  of  food  differentiation  on  consumer  prices and to identify product attributes’ values for the olive oil market. This will con- tribute to device the most appropriate olive oil differentiation strategies in order to be  purchased by consumers in a higher price. The retail price structure was estimated in  relation to several product natural attributes, to production and processing conditions,  to quality control and to labeling and distribution. Findings demonstrate that olive oil  price differentiation is mainly influenced by...

Managing European Corn Borer Resistance to Bt Corn with Dynamic Refuges
Provedor de dados: 31
Autores: Secchi,   Silvia; Hurley,   Terrance M.; Hellmich,   Richard L.
Genetically engineered Bt (Bacillus thuringiensis) corn provides farmers with a new tool for controlling the European corn borer (ECB). The high efficacy and potential rapid adoption of Bt corn has raised concerns that the ECB will develop resistance to Bt. The Environmental Protection Agency has responded to these concerns by requiring farmers to plant refuge corn. Current refuge requirements are based on models that do not consider the value of dynamically varying refuge in response to increased scarcity and diminished control over time or the importance of backstop technologies currently being developed. The purpose of this paper is to evaluate dynamically optimal refuge requirements with the arrival of alternative backstop technologies and to compare...

Bioethanol production under endogenous crop prices: Theoretical analysis with an empirical application to barley
Provedor de dados: 31
Autores: Rinne,   J.; Lankoski,   Jussi E.; Ollikainen,   Markku.
The European Union’s Emission Trading Scheme (EUETS) and the current renewable resource program provide strong incentives to use agricultural crops either for combustion in power plants to produce electricity and heat or as a feedstock for transportation fuels. In this paper we examine the social desirability of ethanol production from agricultural crops. To endogenize the competition on land use, we employ a Ricardian model of heterogeneous land quality, where land is allocated to alternative crops on the basis of their relative profitability. The model comprises three land use types: bioenergy crop, conventional feed crop and green setaside. Industry demands crops for both ethanol and feed production. Effects on the GHG balance are explicitly taken into...

Autores: Urcola,   Hernan A.; Schnitkey,   Gary D.; Irwin,   Scott H.; Sherrick,   Bruce J.
This study uses corn yield data from McLean County, Illinois to test whether farmer skill influences yields.  This analysis is conducted by performing persistency tests on unadjusted, soil productivity adjusted (PA), and productivity and input intensity adjusted (PIA) yields.  Correlation analysis and winner/loser tables indicate that unadjusted, PA, and PIA yields exhibit persistency across time. PIA yields exhibiting persistency is consistent with farmer skill influencing yield.  Hence, our results support the hypothesis that farmer skill influences yields.

Labor-Intensive U.S. Fruit and Vegetable Industry Competes in a Global Market
Provedor de dados: 31
Autores: Calvin,   Linda; Martin,   Philip L.
The U.S. fruit and vegetable industry is labor intensive, pays higher wages than are paid in many other countries, and increasingly operates in a global economy. U.S. fruit and vegetable farms rely on seasonal workers who are likely to be unauthorized immigrants; any future immigration reform could reduce the supply of labor or raise wages. Fruit and vegetable growers may respond to any potential wage increases by reducing the number of seasonal workers employed, adopting mechanized harvesters or other labor-saving technologies in the field, or reducing production.

Deregulation of the Maize Marketing System of Swaziland and Implications for Food Security
Provedor de dados: 31
Autores: Mashinini,   Nkosazana N.; Obi,   Ajuruchukwu; van Schalkwyk,   Herman D.
Recent shortfalls in the supply of maize in the Kingdom of Swaziland have exacerbated the country's growing food insecurity and led to fresh calls for full deregulation of the maize marketing system. The proponents of deregulation believe that it eliminates inefficient production and service units by transferring resources to their best alternative uses. While the theoretical foundations for that position are not questionable, no studies have to date explicitly investigated the effects of the current arrangements and the potential effects of full deregulation. This paper reports on a study that examined the welfare effects of the regulation of the country's maize industry and considered the likely impacts of full deregulation of the industry. Using a...

Effects of Price Volatility and Surging South American Soybean Production on Short-run Soybean Basis Dynamics
Provedor de dados: 31
Autores: Zhang,   Rui (Carolyn); Houston,   Jack E.
This study investigates the effects of South American production (SAP) and futures volatility on the soybean price dynamics in terms of their effects on the basis. The results of the econometric model showed that both South American production and futures volatility of the nearby contract have negative effects on the basis though in the forecast model, lagged values of these two factors failed to predict basis change in the future. If information about the change of the expected SAP or futures volatility is available, then the model can predict the changes in basis. This information would be helpful for hedgers to decide the time to lift their hedge.

BIOPHYSICAL SIMULATION IN SUPPORT OF CROP PRODUCTION DECISIONS: A CASE STUDY IN THE BLACKLANDS REGION OF TEXAS
Provedor de dados: 31
Autores: Dillon,   Carl R.; Mjelde,   James W.; McCarl,   Bruce A.
Economic feasibility of Texas Blacklands corn production in relation to sorghum, wheat, and cotton is studied. Biophysical simulation generated yield data are integrated with an economic decision model using quadratic programming. Given the various scenarios analyzed, corn is economically feasible for the Blacklands. A crop mix of half corn and half cotton production is selected under risk neutrality with wheat entering if risk aversion is present. Corn and grain sorghum production are highly substitutable. Profit effects attributed to changing corn planting dates are more pronounced than profit changes resulting from altering corn population or maturity class.

The impact of Access to Credit and Training on Technological Adoption: A Case of the Rice Sector in Tanzania
Provedor de dados: 31
Autores: Nakano,   Yuko; Kajisa,   Kei.
Using an extensive household-level data set collected in Tanzania, this paper investigates the determinants of the technological adoption of rice cultivation and of paddy yield. We especially focus on the impact of credit and training on the adoption of modern technologies. Based on empirical results, we argue that modern inputs and improved practices of rice cultivation enhance the increase in paddy yield. We also argue that the impact of credit and training on the adoption of modern technologies can differ for different technologies. If the adoption of a specific technology does not require a large amount of cash, knowledge given by training is sufficient to enhance adoption. On the other hand, those who can access credit or self-finance can adopt...

Provedor de dados: 31
Autores: Larson,   James A.; Gwathmey,   C. Owen; Roberts,   Roland K.
Farmers are concerned about the high costs of transgenic seed and technology fees associated with the large plant population densities recommended for ultra-narrow row cotton.  This study evaluated the effects of alternative plant population density decision criteria on net revenues under different lint price and transgenic seed cost scenarios.  Results indicate that farmers may be able to maximize profits by seeding for a target plant population density of approximately 15.5 plants m-2.

Industry Organization and Output Size Distribution of Cotton Gins in the U.S.
Provedor de dados: 31
Autores: Mutuc,   Maria Erlinda M.; Hudson,   Darren.
With cotton output declining by 46 percent from 2005-2008 (from 23.89 M bales in 2005 to 12.8 M bales in 2008), gins are processing less cotton.  This paper examines how output size distribution of cotton gins in the U.S. has evolved and the extent to which the developments in the U.S. ethanol industry, specifically the passage of the Energy Policy Act in 2005 (and its subsequent revisions), have influenced this structural process.  Markov transitional probability matrices (TPMs) are estimated for two periods: 1994-2004 and 2005-2008 to determine changes in output size distribution of gins.  TPMs indicate that relative to the pre-2005 period, gins had a greater propensity to process lower outputs after 2005. It is purported that in industries constrained...

Cassava production in Benin is still characterized by low productivity compared to those of sub regional countries. Improved cassava varieties have been then developed. They have been promised to raise the productivity and thereby the income of farmers. This study examines the relationship between agricultural technology adoption and productivity improvement with focusing on high yield cassava varieties. The data used were collected from 267 randomly selected cassava producers in Benin. The paper uses the counterfactual outcomes framework of modern evaluation theory to estimate the Average Treatment Effect (ATE) of high yield cassava varieties adoption on farm-level average yield. Results indicate that the adoption of high yield cassava varieties...

The effect of policy on the Southern African Valencia industry
Provedor de dados: 31
Autores: Joubert,   Christo J.; van Schalkwyk,   Herman D.
The policy analysis matrix (PAM) was used in this study to determine the definable impact of policies on the Southern African Valencia industry. By using a PAM the effects of divergences between private and social values of revenue, tradable inputs, domestic inputs and profits are determined. With the calculation of the private cost coefficient, domestic resource cost coefficient, nominal protection coefficients on tradable outputs and inputs, effective protection coefficient, profitability coefficient and the producer subsidy ratio the effect that government policies had on the Southern African Valencia industry was highlighted. The results show distortions in the market, comparative advantages and the sensitivity of the industry.

Estimating an Ex Ante Cost Function for Belgian Arable Crop Farms
Provedor de dados: 31
Autores: Hansen,   Kristiana; Baudry,   Alexandre; De Blander,   Rembert; Frahan,   Bruno Henry de; Polome,   Philippe.
We estimate a farm-level cost function for Belgian crop farms using FADN data over the study period 1996-2006. We rely on an estimation of farmers' expected yields at the time cropping decisions are made rather than actual yields observed in the FADN data. The use of an ex ante cost function improves the cost function estimation. We subsequently suggest how our cost function can be used in simulations to analyze farmer response to changes in output price risk.

Potential economic impacts of providing for Aquaculture Management Areas in Canterbury
Provedor de dados: 31
Autores: Meyer-Hubbert,   Gerit; Cullen,   Ross.
This research estimates the commercial costs and benefits associated with selected aquaculture projects in the Canterbury region. Mussel farming employment will most likely be generated in coastal communities that at present have few employment opportunities. These communities are likely to profit as well from increased infrastructure needs for the marine farming enterprise. Any development in the marine farming industry will take many years to reach full potential. This means that the costs and benefits from increased marine farming activities will be staggered over a number of years. It is acknowledged that the gains might be achieved at different locations than the losses occur. The effects on other stakeholders are often uncertain.

This article summarizes a study of consumers' willingness to pay (WTP), in urban areas in Tennessee, Mississippi, and Michigan, for a powdery mildew resistant dogwood tree. Powdery mildew is a disease affecting flowering dogwoods that can limit growth, detract from the appearance, and may cause plant decline and death.  Study objectives were to provide information about consumers' WTP and to identify potential marketing strategies for the introduction of the disease-resistant tree. On average, survey respondents indicated they are willing to pay a $13.35 premium for a flowering dogwood tree which is resistant to powdery mildew. Regression results led to inferences that the presence of dogwoods in a respondent's yard, presence of dogwoods infected with...

THE DYNAMIC EFFECTS OF AGRICULTURAL SUBSIDY PROGRAMS IN THE UNITED STATES
Provedor de dados: 31
Autores: de Gorter,   Harry; Fisher,   Eric O'N.
This paper analyzes the dynamic effects of the acreage restrictions and land diversion requirements that are characteristic of the farm subsidy programs in the United States. The subsidy payments a farmer receives are based upon historical base acreage, and it 1s sometimes optimal for a farmer not to participate in a pr9gr~m in order to increase base acreage in anticipation of higher future subsidies. This paper determines the farmer's optimal policy as the solution to a deterministic dynamic program. It shows that farmers with low base acreage typically opt out of these programs, whereas those with high base acreage participate in them. The paper concludes with an examination of aggregate data from the programs involving barley, corn, cotton, oats, rice,...

AN EVALUATION OF SELECTED DECISION MODELS: A CASE OF CROP CHOICE IN NORTHERN THAILAND
Provedor de dados: 31
Autores: Vieth,   Gary R.; Suppapanya,   Pramote.
This research examines the predictability of a profit maximization model, an expected value-variance utility maximization (E-V) model, and two versions of the target-MOTAD model for modeling risky agricultural production decisions. Model solutions were translated into expected value and variance of farm income for analysis. Direct comparison and chi-square analysis of actual and predicted expected income distributions were used in the analyses. It was concluded that the utility maximization and cash-cost target-MOTAD models predicted distributions of farm income better than the variable-cost target-MOTAD and profit maximization models.

Autores: Mutambatsere,   Emelly; Mabaya,   Edward T.; Christy,   Ralph D.
For most countries in southern Africa, food security has been addressed through self-sufficiency, traditionally attained through widespread government involvement in the input and output markets for major food commodities.  Food policies through the 1980’s have been characterized by input subsidies for farmers; fixed, pan-seasonal and pan-territorial farm level pricing systems, mainly implemented through parastatal marketing boards; as well as subsidies and price controls at the wholesale and retail levels.  Under Structural Adjustment Programs of the 1990’s, most of those policies were abandoned for more market oriented policies.  During the same period, many countries in the region joined the multilateral trading system, and on a regional level, two...

PROFITABILITY OF ALFALFA HAY STORAGE USING PROBABILITIES:  AN EXTENSION APPROACH
Provedor de dados: 31
Autores: Shane,   Ronald L.; Myer,   Gordon L.
Film managers are usually faced with making decisions involving risk and uncertainty. A common source of risk and uncertainty is related to price variability. It is possible to attach probabilities to price variability based on historical data, thus providing the manager with additional information to base decisions. The purpose of this study is to develop and present extension information in a form that assists a producer to choose a marketing strategy based on the producer’s own risk preference. This was done by developing profitability of percentage rates of return based on historical data. Alfalfa hay is used as the commodity example.

COMPARATIVE ANALYSIS OF CAPITAL INTENSIVE AND LABOR INTENSIVE RICE IRRIGATED PERIMETERS IN THE SENEGAL RIVER VALLEY
Provedor de dados: 31
Autores: Diallo,   Mamadou Dian.
Senegal is heavily dependent on imported food, particularly rice.  During the late sixties and early seventies the Sahelian drought made the country painfully aware how dependent its agriculture is on rainfall.  Irrigation and full water control systems along the major rivers became the "priority of priorities" in the recent Senegalese national plans.  In the Senegal River Valley two major types of irrigation schemes had been implemented along the river valley since 1973:  large scale and small scale irrigated perimeters.  The objectives are to increase rice production and reduce dependence on foreign imports of rice.  This paper analyzed the two types of irrigation schemes in the Senegal River Valley and compares the financial and economic cost of...

One of the Government of Rwanda’s key post-war policy objectives has been to increase agricultural productivity and ensure food security by promoting a transition from semi-subsistence production and marketing practices to intensive production and highly commercialized agricultural markets. The government wants farmers to increase land and labor productivity through the use of modern inputs, thereby generating substantial surpluses which can be sold to pay for inputs and generate increases in farm incomes.

Autores: Alemu,   Zerihun Gudeta; Oosterhuizen,   K.; van Schalkwyk,   Herman D.
This paper quantifies the responsiveness of producers of teff, wheat, maize and sorghum to incentives using an error-correction model (ECM). It is found that planned supply of these crops is positively affected by own price, negatively by prices of substitute crops and variously by structural breaks related to policy changes and the occurrence of natural calamities. It has found significant long-run price elasticities for all crop types and insignificant short-run price elasticities for all crops but maize. Higher and significant long-run price elasticities as compared to lower and insignificant short-run price elasticities are attributable to various factors, namely structural constraints, the theory of supply and the conviction that farmers respond when...

ASSESSING AND ATTRIBUTING THE BENEFITS FROM VARIETAL IMPROVEMENT RESEARCH: EVIDENCE FROM EMBRAPA, BRAZIL
Provedor de dados: 31
Autores: Pardey,   Philip G.; Alston,   Julian M.; Chan-Kang,   Connie; Magalhaes,   Eduardo Castelo; Vosti,   Stephen A.
In general, reported rates of return to agricultural R&amp;D are high, but questions have been raised about upward biases in the evidence. Among the reasons for this bias, insufficient attention to attribution aspects-matching of research benefits and costs-is a pervasive problem, the magnitude of which is illustrated here with new evidence for Brazil. Over the period 1981 to 2003, varietal improvements in upland rice, edible beans, and soybeans yielded benefits attributable to research of $14.8 billion in present value (1999 prices) terms; 6.1 percent of the corresponding value of crop output. If all of those benefits were attributed to Embrapa, a public research corporation accounting for more than half Brazil's agricultural R&amp;D spending, the...

The Global Welfare Effects of GM Sugar Beet under Changing Sugar Policies
Provedor de dados: 31
Autores: Dillen,   Koen; Demont,   Matty; Tollens,   Eric.
Since most of the recent agricultural biotechnology innovations have been developed by private companies, the central focus of societal interest is on the distribution of the gains from these technologies among all stakeholders. In a partial equilibrium model, assuming perfect corporate pricing strategies given the heterogeneous population of potential adopters, we model the worldwide introduction of GM sugar beet. The introduction is modelled under both the old and new CMO for sugar in the EU. We see GM sugar beet could bring great benefits to both consumers in the world and sugar beet producers even when the innovation is protected by intellectual property rights and the innovator uses his restricted monopoly to the full extend.

Provedor de dados: 31
Autores: Ouma,   Emily Awuor; Jagwe,   John.
Smallholder farmers in developing countries need to improve their position in food value chains in order to improve their margins and as a strategy for coping with agricultural food price volatility through innovations within the chains. Value chain mappings and gross margin analysis were employed to assess constraints and opportunities for existing value chains for bananas in Central Africa using market survey data. The results showed weak linkages within the banana value chains with poor integration of value chain actors and minimal involvement with regional markets and high-value domestic chains such as supermarkets. Value addition in terms of agroprocessing was carried out at small scale levels using rudimentary techniques limiting the final product to...

THE CHOICE BETWEEN CONVENTIONAL AND ORGANIC FARMING – A HUNGARIAN EXAMPLE
Provedor de dados: 31
Autores: Ferto,   Imre; Forgacs,   Csaba.
The organic agriculture represents a promising alternative for the future of European agriculture. It is consistent with the notion of sustainable development set forth already in the 1992 CAP Reform. Despite of increasing importance of organic farming, the research on organic farming is still limited. This scarcity of the research is especially true for New Member States of the enlarged EU. This paper investigates the choice between conventional and organic production technologies for individual farmers in Hungarian agriculture. We apply a model that explicitly accounts for the effects of farm-specific variables like age and education on the expectations farmers have on the utility of both production technologies. In addition we take into account the...

Commerce International des Céréales et Production Céréalière au Mali
Provedor de dados: 31
Autores: Dembele,   Niama Nango.
The liberalization of foreign trade has positively impacted the production of cereals in Mali. The increase in the production of cereals is due to both price increases and the effectiveness of the marketing system. The liberalization made Mali a cereal exporter in contrast with its former status ten years ago, that of a cereals importer Mali supplies its neighboring countries such as Mauritania, Niger, Burkina Faso, Senegal and Cote d’Ivoire with coarse grains. However, subsidies, rapid urbanization, and changes in the food habits of the urban population threaten Mali’s capacity to remain an exporter. To remain an exporter, Mali should, in the long term, process coarse grains into products conforming to the expectations and food habits of the urban...

Autores: Rosario,   Joe A.
Much water has flowed under the bridge since ministers failed to conclude world trade negotiations in July 2009. The world underwent an historical recession brought about by the U.S. financial toxic asset scandal. Global trade has declined sharply and is forecasted to decline by 9% in real terms in 2009. World economic growth rates have declined dramatically. There have been several cases of covert (and some overt) protectionism by both developed and advanced economies. Despite declarations from world leaders on several occasions for the need to refrain from protectionist measures and the need for the resumption and conclusion of the Doha Round of trade negotiations over the past nine months, no such action has materialized. The two major contestants in...

Autores: Aly,   Hassan Y.; Belbase,   Krishna P.; Grabowski,   Richard; Kraft,   Steven E.
The purpose of this paper is to measure the extent of technical inefficiency among a sample of Illinois grain farms using the corrected ordinary least squares method. Instead of assuming a Cobb-Douglas production function, a linear form of the ray-homothetic is used. The results show a significant amount of technical inefficiency among all the farms in the sample, but with large farms being less technically inefficient than small farms.

The Economic Impacts of Bioenergy Crop Production on U.S. Crop Production
Provedor de dados: 31
Autores: Torre Ugarte,   Daniel de la; Walsh,   Marie E.; Shapouri,   Hosein; Slinsky,   Stephen P.
In  response  to  energy  security  concerns,  alternative  energy  programs  such  as  biomass  energy  systems  are  being developed to provide energy in the 21st century. For the biomass industry to expand, a variety of feedstocks will need to be utilized. Large scale production of bioenergy crops could have significant impacts on the United States agricultural sector in terms of quantities, prices and production location of traditional crops as well as farm income. Though a number of scenarios were examined to study the impact of bioenergy crop production on the agricultural sector, two cropland scenarios are presented in this report. Under the wildlife management scenario, the analysis indicates that, at $30/dry  ton  (dt)  for  switchgrass,...

Autores: Poonyth,   Daneswar; van Zyl,   Johan.
This paper evaluates the production structure of the South African agricultural sector for the period 1970-1998, using a translog function. The results show that the production structure is best represented by production technology that is Hicks-neutral and homothetic. This information is useful in evaluating the results of previous research on the structure of South African agricultural production, particularly relatively recent research on elasticities of substitution. In addition, it also provides the basis for meaningful future analysis of aspects related to the production structure of agriculture.

This study provides an empirical assessment of the competitiveness of Albanian dairy and wine production, based on specifically collected survey data. For both product groups, the analysis is carried out on two levels: farm level production of raw material and processing and manufacturing of the final product in the food industry. In a third step, both levels are aggre-gated to analyse the competitiveness of the entire production chain for each product group. Overall, the wine sector appears in an economically more favourable situation than the milk sector. Although there is currently no relevant export of wine, there has been considerable in-vestment activity at the farm level and the harmonisation of quality standards with EU legislation is currently...

Autores: Burt,   Oscar R.; Worthington,   Virginia E.
The dynamic structure of wheat acreage supply response is considerably more complex than previous studies have recognized.  The distributed lag response is saw-toothed in its pattern, which is believed to eminate from the influence of summer fallow in crop rotations in the Great Plains.  The acreage response elasticity estimate for the Great Plains at mean price was 1.3, and for the aggregate U.S. it was 1.5.  For the Unites States, the proportion of long-run response experienced over the first five years from an increment to price was .24, .44, .70, .95, and. 99.

The Value of Inherent Soil Characteristics: A Hedonic Analysis
Provedor de dados: 31
Autores: Samarasinghe,   Oshadhi; Greenhalgh,   Suzie.
In an attempt to value soil natural capital, we use the inherent characteristics of soil and land valuation data to examine the relationship between soil characteristics and rural farmland values in the 6000ks2 Manawatu catchment in New Zealand. The study applies a hedonic pricing method to determine if the value of ‘critical’ inherent characteristics of soils are reflected in land values. We find empirical evidence that the examined characteristics of soil natural capital stock, e.g., particle size, drainage, potential rooting depth and profile available water, are in fact reflected in rural land values.

Autores: Hyde,   Jeffrey; Martin,   Marshall A.; Preckel,   Paul V.; Buschman,   Lawrent L.; Edwards,   C. Richard; Sloderbeck,   Phillip E.; Higgins,   Randall A.
While most Corn Belt farmers consider planting Bt corn to control European corn borer, southwestern Kansas farmers must also take into account an array of other insect pests, including corn rootworm, spider mites, and southwestern corn borer. This research uses a decision analysis framework to estimate the expected economic value of Bt corn in southwest Kansas. Mean per acre Bt values ranged from $12.49 to $34.60, well above the technology fee assumed to be $14 per unit, or $5.25 per acre at a seeding rate of 30,000 seeds per acre. The minimum value over all scenarios was $8.69 per acre. Using Monte Carlo simulation, it was shown that European and southwestern corn borer infestation probabilities, expected corn price, and expected pest-free yields are...

Evaluating Benefits from Subsistence Pearl Millet Production in the Northern Communal Area of Namibia
Provedor de dados: 31
Autores: Matanyaire,   C.M.
Using experimental data from the northern Namibia pearl millet based subsistence sector the gross margins (GM) and savings on food expenditure (SFE) were computed and compared. The value to cost ratios from the SFE approach were higher than those from the GM approach implying that investment into the selected technologies would be more attractive under subsistence production than under commercial production. This underlines the importance of change agents not to change the farmers' target for farming. Furthermore, it helps explain why subsistence farmers continue to farm when all GM calculations show that they are always loosing money.

The Economics of Annual Legume and Double Legume Cover Cropping in Southern Minnesota
Provedor de dados: 31
Autores: McLellan,   Ashleigh; Carlberg,   Jared G.
Using historical data from crop producing farms in southern Manitoba, this study quantifies the economic savings that could be realized by using legumes to supply nitrogen in a cereal-oilseed based rotation. Stochastic budgets are developed for four alternative crop rotations and the returns associated with each are evaluated using the utility-based risk ranking methods of stochastic dominance and stochastic efficiency. It is found that including a legume cover crop in a cereal-oilseed based rotation can reduce the amount of nitrogen required by a subsequent crop and in turn increase the net returns associated with the complete crop rotation.

Economic Outlook for Representative Cotton Farms Given the August 2006 FAPRI/AFPC Baseline
Provedor de dados: 31
Autores: Richardson,   James W.; Outlaw,   Joe L.; Knapek,   George M.; Raulston,   J. Marc.
The majority of the cotton farms are in poor overall financial condition under the August 2006 Baseline. Drought conditions this year will deplete cash built from more favorable yields in 2004 and 2005 in many cases. In addition, the poor financial performance of the farms is attributed in part to the large increase in input prices. Fuel costs, previously projected to decrease modestly in 2005 and 2006, are now more accurately depicted as significant increases, building further on the large increases experienced in 2003 and 2004. The increase in cost is not limited to fuel expense for trucks, equipment, and irrigation motors, but includes the cost of nitrogen fertilizer and ag-related services which are closely linked to energy prices. Many cotton...

Measurement of Yield distribution: A Time-Varying Distribution Model
Provedor de dados: 31
Autores: Yang,   Tsung Yu.
Regarding the nature of yield data, there are two basic characteristics that need to be accommodated while we are about to model a yield distribution. The first one is the nonstationary nature of the yield distribution, which causes the heteroscedasticity related problems. The second one is the left skewness of the yield distribution. A common approach to this problem is based on a two-stage method in which the yields are detrended first and the detrended yields are taken as observed data modeled by various parametric and nonparametric methods. Based on a two-stage estimation structure, a mixed normal distribution seems to better capture the secondary distribution from catastrophic years than a Beta distribution. The implication to the risk management is...

Coffee is the most important export crop in Uganda and an important source of income among smallholder farmers in large parts of the country. The Robusta type dominates coffee production and Ugandan Robusta is demanded by roasters as a component in certain blends due to its special taste qualities. However, a combination of events outside and within Uganda, especially the collapse of world coffee prices in the late 1990s, are eroding farmer incomes and export revenues and threaten the long-term viability of the industry. In this context, the paper first investigates the challenges faced by the Ugandan coffee industry, namely the decline in the world coffee market, changes in procurement strategies among coffee importers, the rapidly expanding market for...

This case study on the former Rice Growers Association (RGA) analyzes the effects of a variety of business decisions and market changes, relative to the ongoing Farmers’ Rice Cooperative (FRC). Interview and survey findings reveal that many respondents felt RGA’s Board of Directors was passive and, despite its large size, lacked the necessary expertise to direct management and represent the best interest of the broader cooperative membership. In the midst of challenging market conditions, RGA’s management teams were accused of making a number of poor business decisions that led to significant financial stress and the eventual dissolution of the firm.

This paper analysis the effects of farmer characteristics, farm structure and farm performance on farm renewal and farm growth. The data set used in this research consists  of panel data from the Dutch Farm Accountancy Data Network of farms specialized in plant production extended with a data from survey among those farms. Probit models were used to determine the likelihood of the changes. Results show that the degree of mechanization increases the probability of farm growth and farm renewal. Family labour  input and solvency have a negative impact on farm growth. Farm size is positively correlated with farm renewal. No indications of the influence of the life cycle have been  found.

Provedor de dados: 31
Autores: Colby,   Hunter; Diao,   Xinshen; Somwaru,   Agapi.
A growth accounting method is used to analyze the sources of growth in China's rice, wheat, corn and soybeans, the four most important crops in China's grain sector, during 1978-97.  A large TFP contribution to growth in grain production is found in the period immediately following China's rural economic reform (1978-85).  In recent years the growth rate of TFP falls sharply, contributing less than 20 percent of growth in grain production, as increased use of inputs became the major engine of growth.  If the current government policy environment remains unchanged, China's grain production will become increasingly costly and constrain future growth and competitiveness in world grain markets.  The supply response of the four grains is estimated using a...

2003 OUTLOOK OF THE U.S. AND WORLD SUGAR MARKETS, 2002-2012
Provedor de dados: 31
Autores: Koo,   Won W.; Taylor,   Richard D.
This report evaluates the U.S. and world sugar markets for 2002-2012 using the Global Sugar Policy Simulation Model.  This analysis is based on assumptions about general economic conditions, agricultural policies, population growth, weather conditions, and technological changes.   Both the U.S. and world sugar economies are predicted to improve over the next 10 years after the current over-supply is reduced. World demand for sugar is expected to grow faster than world supply, resulting in Caribbean sugar prices gradually increasing from 7.88 cents/lb in 2002 to 12.15 cents/lb in 2012. The U.S. wholesale price of sugar is projected to increase from 21.76 cents/lb in 2002 to 25.28 cents/lb in 2012, if the United States maintains its sugar programs. World...

Yield Information Needed for the Analysis of Crop Improvement Research
Provedor de dados: 31
Autores: Dalrymple,   Dana G.
The purpose of developing new crop technology is generally to increase yields per unit of land and to reduce costs per unit of product. A rather elaborate' methodology has been developed to measure the rates of return from such investments, principally involving ex post analysis. Improvements to this methodology are continually being suggested.1/ Yet much of this sophisticated methodology is built on a rather limited statistical base--particularly when it comes to the actual measurement of the effect of the technology on yields. Some of these yield measurement problems, such as the difficulties in isolating the yield effect of a specific technology when it is part of a package of interacting technologies, have long been recognized. The influence of weather...

Factors Influencing ACRE Program Enrollment
Provedor de dados: 31
Autores: Woolverton,   Andrea E.; Edwin,   Young.
Authorized by the 2008 Farm Act, the Average Crop Revenue Election (ACRE) program is the first revenue-based, income-support program that calculates payments using recent market prices and a producer’s actual plantings. The payments are triggered when a farm’s revenue and State revenue (price multiplied by yield per planted acre) fall below a calculated guarantee for a crop. By contrast, other income-support programs are based on legislated rates and support levels, computed using a farm’s base acres and payment yields. Had the ACRE program been available during crop years 1996-2008, this report shows that farmers would have benefited more from participating in 2002 Farm Act programs than in the hypothetical ACRE program. The report further suggests that,...

SPECIFICATION OF AGRICULTURAL SUPPLY FUNCTIONS - EMPIRICAL EVIDENCE ON WHEAT IN SOUTHERN N.S.W
Provedor de dados: 31
Autores: Griffiths,   William E.; Anderson,   Jock R.
The implications of alternative disturbance specifications in supply functions have been considered in recent theoretical work but little, if any, empirical evidence has been provided on such specifications. Any empirical investigation of the nature of a supply function disturbance is hampered by considerable uncertainty about the deterministic part of the function. Nevertheless, some progress might be made by considering alternative disturbance specifications in conjunction with a variety of deterministic specifications. Applying this approach to the supply of wheat in southern N.S.W., we find some empirical support for an additive disturbance and, surprisingly, for the use of price, rather than revenue, as an argument In supply functions.

LIBERALIZATION'S IMPACT ON THE INDIAN SEED INDUSTRY: COMPETITION, RESEARCH, AND IMPACT ON FARMERS
Provedor de dados: 31
Autores: Pray,   Carl E.; Ramaswami,   Bharat.
This article attempts to measure the impact of India’s limited liberalization on the seed industry and on farmers.  Using a unique data set on the structure, research, and sales of private seed firms at two points in time, 1987 and 1995, we provide evidence that liberalization increased the competitiveness of the seed industry, and increased the amount of research by Indian and foreign seed firms.  Then, using government district level data and data collected from these firms, we show that private hybrids increased farmers’ yields.  This suggests that Indian farmers are the true beneficiaries of liberalization and that policies that encourage more competition and more research will provide future benefits to farmers.

The Impact of Agricultural Policy Distortions on the Productivity Gap: Evidence from the Rice Production
Provedor de dados: 31
Autores: Rakotoarisoa,   Manitra A.
This study determines how production and trade policy distortions affected rice productivity in thirty-three rice-producing countries.  A rice-productivity index for each country is constructed, and a model linking the productivity gap with policy distortions is presented.  After controlling for the differences in infrastructure, openness, and human capital, this article shows that high subsidies and protection in developed countries combined with taxation of rice farming in poor countries have widened the gap in rice productivity between rich and poor rice countries.

In this article, justifications by producers (economic protectionism), consumers and social advocates (humanitarian motives) for including labour standards in international trade agreements are discussed. To date, little work has been undertaken to determine empirically whether low labour standards lead to trade distortions. This article provides some empirical evidence pertaining to this question. Consumer groups, social advocates and traditional vested interests such as labour unions have attempted to have labour standards included in WTO disciplines. In the absence of success at the WTO, the relationship between labour standards and international trade has, however, been evolving in the areas of private standards and preferential trade agreements.

This report reviews the impacts of the Asian Maize Biotechnology Network (AMBIONET), organized by the International Maize and Wheat Improvement Center (CIMMYT) with funding from the Asian Development Bank to strengthen the capacity of public maize research institutions in China, India, Indonesia, Philippines, Thailand, and Vietnam to produce high-yielding, disease resistant, stress tolerant maize cultivars. It was found that, during its lifetime (1998-2005), AMBIONET clearly benefited researchers and institutions in participating countries, as well as CIMMYT. In addition, there was good progress toward developing improved cultivars. Asian farmers are just beginning to gain from the work, but their future benefits will likely pay for AMBIONET’s relatively...

Stochastic Dynamic Northern Corn Rootworm Population Model
Provedor de dados: 31
Autores: Mitchell,   Paul D.; Riedell,   Walter.
A complete life cycle model for northern corn rootworm, Diabrotica barberi Smith and Lawrence, is developed using a published single-season model of adult population dynamics and data from field experiments. Temperature-dependent development and age-dependent advancement determine adult population dynamics and oviposition, while a simple stochastic hatch and density-dependent larval survival model determine adult emergence. Dispersal is not modeled. To evaluate the long-run perform nce of the model, stochastically generated daily air and soil temperatures are used for 100-year simulations for a variety of corn planting and flowering dates in Ithaca, NY, and Brookings, SD. Once the model is corrected for a bias in oviposition, model predictions for both...

The Uganda government has since 1987 initiated a sequence of tax reforms to address the fiscal challenges facing the country. This paper uses a Computable General Equilibrium (CGE) model to analyze the welfare effects of tax reforms on households and the impact of these challenges on production and firm activities. The findings are consistent with previous studies which found that the introduction of VAT was indeed a progressive policy reform. Zero rating all food items and agricultural products mainly benefit the low income households whose consumption basket is mainly food items. In a quest for further sources of revenue by overtaxing the rich, this could generate further revenues albeit lower savings and investments by this group. Finally, over-reliance...

Risk aversion and sustainable maize production in Nigeria: Some challenges and prospects for agricultural and economic development
Provedor de dados: 31
Autores: Olarinde,   Luke O.; Manyong,   Victor M.
This paper determines the degree or extent of farmer’s risk aversion that affects sustainable maize production in Northern Nigeria. Using a ridge regression analysis, a measure of risk aversion was derived for each individual farmer in a model of safety-first behaviour from a cross-sectional survey of 350 maize producers in northern Nigeria. The distribution of the degree of risk aversion shows a high skewness towards the risk averters (high risk farmers) and centered around 1.20, and standard deviation of 0.37. This distribution is then explained by a set of specific variables that characterize the farmers’ behaviour in the study area using a Tobit model. Susceptibility to risk was found to be highly premised on the socioeconomic factors (e.g. age of...

This study estimated a dynamic logistic model to explain the diffusion Bt cotton in the United States. Regional differences in the speed and extent of Bt cotton adoption were explained by differences in availability of Bt seed adapted to local conditions, potential seed supplier profits, and economic variables affecting grower gains from adoption. The study also estimated the impact of Bt cotton on insecticide use, controlling for differences in pest infestations and prices and correcting for the endogeneity of the Bt adoption decision. Bt cotton significantly reduced insecticide applications to control target pests – cotton bollworm, tobacco budworm, and pink bollworm. Bt cotton has led to an overall reduction in these applications per total US cotton...

Quality Signaling through Certification
Provedor de dados: 31
Autores: Auriol,   Emmanuelle; Schilizzi,   Steven.
This paper analyzes the problem raised by quality provision in globalizing economies. When quality is a credence attribute, there is a signaling problem and quality drops to its minimum level. A way out of this under-provision equilibrium consists to rely on certification. However certification of goods involves costs, most of which are fixed, because to credibly signal quality, the certification process has to be carry out by an independent authority above all suspicion. The certification costs, which might justify a centralized intervention, become a major force in deciding market structure. Then in a given population the rate of certification depends on the consumers' wealth and size. If the population is too poor the market for certification collapses...

SUPPLY RESPONSES IN THE SOUTH AUSTRALIAN POTATO INDUSTRY
Provedor de dados: 31
Autores: Mules,   T.J.; Jarrett,   Frank G.
The potato industry in South Australia is characterised by very unstable prices. One hypothesis for this instability is that potato growers' acreage responses follow a cobweb pattern, that is, a one year lag of acreage to price. This hypothesis is tested, together with a two year lag and a distributed lag. The distributed lag model seems the most satisfactory and gives a short-run elasticity of acreage to price of 0.36 and a long-run elasticity of 1.09. An alternative to the lagged price hypothesis is the "constant cash return" hypothesis which postulates that potatoes are grown to provide a certain cash income to permit farm development. This explanation of acreage response only seems relevant in the dairying and fat lamb areas of the State.

OPTIMAL RATE OF APPLIED NITROGEN AND CHOICE OF REDUCED TILLAGE
Provedor de dados: 31
Autores: Bocoum,   Kolado; Stoecker,   Arthur L.
The objective was to compare optimal long-term farm level investments in conservation tillage systems and annual nitrogen use in wheat production from a private and social perspective. The performance of four tillage systems was simulated on a 243 hectare (600-acre) Oklahoma wheat farm with six soil types. A decomposition method was used to find the optimal tillage system. It was found that private producers would select a disk chisel system while the less erosive sweep system was optimal from a social perspective.

An assessment of the social impact of treadle pump technology for manual irrigation in eastern India, the Nepal Terai, and Bangladesh, South Asia's so-called "poverty square." Treadle pump technology can be a powerful tool for poverty reduction in this region. It "self-selects" the poor, and puts to productive use the region's vast surplus family labor. It is claimed that the treadle pump could raise the annual net household income by US$100, on the average.

The Role of the Private Sector in Transferring Hybrid Corn Technology
Provedor de dados: 31
Autores: Pray,   Carl E.; Echeverria,   Ruben G.
It is widely accepted that new technology is an important source of agricultural growth. Developing countries have tried a variety of policies to accelerate the development and diffusion of new technology. These policies include: (1) government investment in agricultural research and extension, (2) tax breaks and other incentives to private companies that conduct agricultural research, and (3) incentives to transfer new technology developed outside the country. At the same time, many countries have other policies that reduce the incentive of private companies to do research or transfer technology. These include restrictions on importing technology and importing research inputs, restrictions on which companies are allowed to do research, and regulations...

Grain Contracting Strategies to Induce Delivery and Performance in Volatile Markets
Provedor de dados: 31
Autores: Wilson,   William W.
One of the impacts of higher prices along with greater volatility in futures and basis is that there is pressure for an escalation in cash contracting for grain. This volatility has resulted in an unprecedented level of contracting with growers for specific purchases in recent years. There is a wide array of cash contracts with varying terms. Beyond that array, there is also a growing realization of growers not delivering on contracts, in part due to escalation in post-contract prices. This realization is evolving as a major strategic issue for buyers and the marketing system, particularly as buyers seek to use such contracting strategies as an element of risk mitigation. There are three purposes of this article. First is to provide a broad survey of...

Autores: Nott,   Sherrill B.
The sources of the 51 cash grain farms analyzed in this report were Telfarm/MicroTel at Michigan State University, plus the AgriSolutions offices in East Lansing, Adrian, Mt. Pleasant, and Alpena. Farm types were assigned using the 1992 Census of Agriculture's Standard Industrial Classification (SIC) definitions.  Basically, any farm with 50 percent or more of value of farm sales from one item becomes a farm of that type. Cash grain farms have 50 percent or more of value of combined sales from corn, soybeans, wheat, all varieties of navy beans, oats, and other small grains. This report is a summary of the financial and production records kept by cash grain farmers enrolled in the Telfarm/MicroTel record program through Michigan State University Extension.,...

Autores: Zhao,   Xufu; Tisdell,   Clement A.
After providing information about the global importance of cotton as a textile and China’s and Australia’s contribution to global cotton production, this paper examines and compares trends in the time-series of cotton production of China and Australia for the period 1980-2007. In doing so, it takes account of changes in the area planted with cotton and its yield. Correlation estimates and decomposition analysis are used to determine the relative contribution to variations in the total output of cotton of changes in the total area planted with cotton and its yield in both countries. These relative contributions are found to be quite different for Australia and China. In addition, there is a comparative analysis of fluctuations in the production of cotton,...

Niche Agribusiness Supply Chains and the Channel Coordinator’s Role in their Creation and Management
Provedor de dados: 31
Autores: Patterson,   Alastair; Martin,   Sandra; Mollenkopf,   Diane A.
The role of the channel coordinator and the structure of their supply chains are critical to the success of a supply chain that produces a product targeted at a specific market niche. Without the management of the channel coordinator, focussed on delivering a product with specific attributes to the target niche, the supply chain will be incapable of working in concert and creating a cohesive product offering. The supply chain structure is critical to this process. Although these two concepts are often mentioned in the supply chain and associated literature, and despite their importance, there is very little empirical evidence that shows the linkage between the channel coordinator and the supply chain structure. This paper is based on the analysis of five...

The Renewable Fuel Standard mandates in the Energy Independence and Security Act of 2007 will require 36 billion gallons of ethanol to be produced in 2022. The mandates require that 16 of the 36 billion gallons must be produced from cellulosic feedstocks. The potential land use implications resulting from these mandates were examined using two methods, the POLYSYS model and a general equilibrium model. Results of the POLYSYS analysis indicated that 72.1 million tons of corn stover, 23.5 million tons of wheat straw, and 24.7 million acres would be used to produce 109 million tons of switchgrass in 2025 to meet the mandate.

Finding a sustainable linkage between the emerging farmer and formal markets: The case of pick ‘n pay and the Zanyokwe farmers in the eastern Cape of South Africa
Provedor de dados: 31
Autores: Bediako,   J.A.; Debrah,   Kofi.
A major problem confronting rural and emerging farmers is the marketing of their products. Most of the farmers encountered depend on the local or village markets which are often saturated or purchases are not backed by effective demand to make sales meaningful for the desired benefits. Small scale South African farmers have not been able to access the formal sector to sell their goods. There are several reasons for this which is linked to the nature of the historical evolution of the South African agricultural sector and in particular the food production system. Recently, it has been argued that the small scale farmers are not able to meet the standards that are set by the formal sector and are therefore responsible for their own exclusion by producing...

The paper outlines an approach to estimation and analysis of the futures basis in the U.S. cotton market under weakly rational expectations. Given the model specification derived from the underlying dynamic profit optimization problem of the dealers, the intermediary market model is estimated using the self-organizing state-space (SOSS) approach. Estimation results are used to evaluate the prediction power of the method and test the main assumptions about the existence and consistency of the subjective rational expectations incorporated in the model.

Prices Paid to Cotton Farmers: How Does Zambia Compare to its African Neighbors?
Provedor de dados: 31
Autores: Tschirley,   David L.; Kabwe,   Stephen.
1. Zambia has paid among the best nominal seed cotton prices to farmers in SSA since 1995.  2. By a more refined measure (share of FOT), during 1995-1999, Zambia paid prices comparable to those in Tanzania (a very competitive sector), and substantially higher than in Mozambique and WCA. However, from 2000-2005, Zambia's pricing performance fell, and exceeded only Zimbabwe and Mozambique in our sample  3. The recently announced reference price for 2008 of ZKW 1,200/kg of seed cotton was negotiated and jointly announced by ginners and farmers. It amounts to about 53% of FOT at current exchange rates and Index A prices; about equal to recent shares received by farmers in Zambia, but well below levels in WCA and Tanzania.  4.

Innovation Systems and Technical Efficiency in Developing-Country Agriculture
Provedor de dados: 31
Autores: Mekonnen,   Dawit Kelemework; Spielman,   David J.; Fonsah,   Esendugue Greg.
The paper uses a stochastic frontier analysis of production functions to estimate the level of technical efficiency in agriculture for a panel of 29 developing countries in Africa and Asia between 1994 and 2000. In addition, the paper examines how different components of an agricultural innovation system interact to determine the estimated technical inefficiencies. Results show that the mean level of technical efficiency among the sampled countries was about 86 percent, with some modest increases during the period in question. These results suggest that there is room for significant increases of production through reallocations of existing resources. Despite significant variation among countries, these results also indicate quite a number of least...

Autores: Wilson,   William W.; Jabs,   Eric J.; Dahl,   Bruce L.
A stochastic optimization model was developed to determine optimal testing strategies, costs, and risks of a dual marketing system.  The model chooses the testing strategy (application, intensity, and tolerance) that maximizes utility (minimizes disutility) of additional system costs due to testing and quality loss and allows simulation of the risk premium required to induce grain handlers to undertake a dual marketing system versus a Non-GM system.  Cost elements including those related to testing, quality loss, and a risk premium were estimated for a model representing a grain export chain.  Uncertainties were incorporated and include test accuracy, risk of adventitious commingling throughout, and variety declaration.  Sensitivities were performed for...

Dynamic Diffusion with Disadoption: The Case of Crop Biotechnology in the USA
Provedor de dados: 31
Autores: Fernandez-Cornejo,   Jorge; Alexander,   Corinne E.; Goodhue,   Rachael E.
Controversy over the use of genetically engineered (GE) crops may have induced some farmers to disadopt these seeds, making a traditional diffusion model inappropriate. In this study, we develop and estimate a dynamic diffusion model, examine the diffusion paths of GE corn, soybeans, and cotton, predict the adoption of those crops over the next two years, and explore the main determinants of the diffusion rate. Our estimates indicate that future growth of Bt crops will be slower or negative, depending mainly on the infestation levels of the target pests. Adoption of herbicide-tolerant soybeans and cotton will continue to increase, unless consumer sentiment in the United States changes radically.

Crop genetic resources are the basis of agricultural production, and significant economic benefits have resulted from their conservation and use. However, crop genetic resources are largely public goods, so private incentives for genetic resource conservation may fall short of achieving public objectives. Within the U.S. germplasm system, certain crop collections lack sufficient diversity to reduce vulnerability to pests and diseases. Many such genetic resources lie outside the United States. This report examines the role of genetic resources, genetic diversity, and efforts to value genetic resources. The report also evaluates economic and institutional factors influencing the flow of genetic resources, including international agreements, and their...

Spatial Price Discovery, Dynamics, and Leadership in Evolving Distiller’s Grain Markets
Provedor de dados: 31
Autores: Van Winkle,   Tyler W.; Schroeder,   Ted C.
Recent dramatic growth in corn-based bio-refining has generated considerable growth in the by-product of this process, distiller’s grains. Distiller’s grains are rapidly becoming important livestock feed ingredient sources. However, little public market information is available on distiller’s grain. This study determines spatial and temporal price relationships among distiller’s grain markets. Results indicate spatial distiller’s grain markets operate somewhat independently suggesting potential arbitrage opportunities and indicating distiller’s grain markets are information starved. Furthermore, available futures markets are not viable price risk transfer tools for distiller’s grains.

Market Access by Smallholder Farmers in Malawi: Implications for Technology Adoption, Agricultural Productivity, and Crop Income
Provedor de dados: 31
Autores: Zeller,   Manfred; Diagne,   Aliou; Mataya,   Charles.
In Malawi, maize is the major crop and food staple. Given limited off-farm employment opportunities, much-needed increases in household income for improving food security must come from gains in agricultural productivity through better technology and more profitable crops. In the past, agricultural policy promoted hybrid maize and, more recently, tobacco to increase smallholder income. This paper presents an analysis of what determines the adoption of these two crops and what kind of income effects follow from adoption. Apart from factor endowment and exposure to agroecological risks, differences in the household's access to financial and commodity markets significantly influence its cropping shares and farm income.

SIMULATION OF HARVESTING ASPARAGUS: MECHANICAL VS MANUAL
Provedor de dados: 31
Autores: Cembali,   Tiziano; Folwell,   Raymond J.; Ball,   Trent.
Asparagus harvesting methods and strategies have remained unchanged since inception in Washington. A bioeconomic model was developed to determine the profit optimizing frequency of harvesting for manual and mechanical harvesting techniques. The mechanical harvester is economically viable if the harvester cuts 72.3 percent and 73.55 percent of what a hand crew would cut for process and fresh utilization, respectively. The results indicate that decreasing the frequency of harvest increases profit for asparagus used in processing. This research is the first attempt to address the problem of asparagus harvesting with a bioeconomic model.

Has Imported Rice Crowded-out Domestic Rice Production in Ghana? What has Been the Role of Policy?
Provedor de dados: 31
Autores: Asuming-Brempong,   Samuel; Osei-Asare,   Yaw Bonsu.
Commercial rice imports have accounted for approximately 61%, food aid in rice accounted for about 2%, and domestic rice accounted for some 37% per annum of rice consumption in Ghana over the four years between 2000 and 2003. Compared to the 1990s, these figures show a gradual decline in the share of local rice production in the total quantities of rice consumed in the country. On the other hand, the proportion of food aid in rice consumed has remained relatively constant over the period, while the proportion of commercial imports has increased steadily. Using the Engel-Granger residual-based co-integration test, a market integration analysis was explored for imported rice and domestic rice which compared a central market for imported rice and five key...

Shape Persistence in Elicited Subjective Crop Yield Probability Density Functions
Provedor de dados: 31
Autores: Clop-Gallart,   M. Merce; Juarez-Rubio,   Francisco.
The shape persistence of a crop yield probability density function (PDF) was studied by using two variants of the Visual Impact Method (VIM) to elicit subjective estimations by farmers. In one variant ten weights were used to describe the PDF and in the other variant the farmer chose the number of weights. Results were compared directly and by means of Weibull distributions fitting, with evidence being obtained in favor of methodological persistence and the equivalence of the two estimation methods.

Contributions of U.S. Crop Subsidies to Biofuel and Related Markets
Provedor de dados: 31
Autores: Devadoss,   Stephen; Bayham,   Jude.
The U.S. crop subsidies provide incentives for farmers to expand feedstock production, which benefits the biofuel producers by lowering input costs. This study develops a general equilibrium model to analyze the effects of a reduction in the U.S. crop subsidy on biofuel industries and social welfare. The impacts of feedstock policies on the biofuel market are marginal. In contrast, the biofuel mandate has a larger impact and counteracts the effects of the crop subsidy reduction. The mandate increases the demand for feedstock and causes not only grain ethanol, but also cellulosic ethanol production to rise. The mandate exacerbates the distortion, and government spending increases significantly, leading to greater welfare loss.

Duality theory and static multi-product technology have been applied to analyze aggregate agricultural data by Shumway; Weaver; and McKay, Lawrence and Vlastuin. Several studies (e.g., Antle; Binswanger; and Lopez, 1985a) have indexed technology with a time trend, but no study has attempted to investigate the effects of agricultural research, extension, and education in the multiple-output dual static framework. The objectives of this paper are (i) to assess the bias effects in cash-grain farmers' production decisions caused by public agricultural research, public extension, and farmers' schooling and (ii) to present new estimates of the shadow values of agricultural research, extension, and schooling obtained from the static dual model of agricultural...

Economic Significance of Peanut Production and Income to Georgia Farms, Rural Communities
Provedor de dados: 31
Autores: Shurley,   W. Donald.
Peanuts accounted for 34 percent of Georgia’s crop income and 13 percent of the State’s total farm income in 1992. The total economic impact of peanut production to the Georgia economy is $1.16 billion annually. Per acre, peanuts provide 2.8 times the debt serving capacity of cotton, 6.1 times that of soybeans and 16.4 times that of corn. The peanut price support and quota program adds economic stability to local economies. The value of peanut quota adds an estimated $48 million to Georgia farmland values, which provides collateral for agricultural lenders. A reduction in peanut prices would adversely reduce farm income and cash-flow, quota values, land values, and the real estate tax base of rural communities. Adverse changes may not alter the comparative...

This report is a summary of five years of grape costs and returns data collected from Lake Erie Region grape growers for the 1996 – 2000 seasons. “Concord” and “Niagara” grapes utilized for juice and generic wine accounted for over 90 percent of the survey acreage. About two-thirds of the acreage surveyed was in New York and one-third from Pennsylvania. In recent years, about 40 growers participated, with total vineyard acreage of just over 4,000. Average costs per acre were $1,559 including an imputed value for the operator’s labor. Major cost categories were paid labor ($341 per acre), depreciation ($200), interest ($126), operator labor ($125) and chemicals ($105). Average yield per farm was 6.4 tons per acre (with a range of 3.6 to 9.8 tons per acre)....

Land Use Consequences of Crop Insurance Subsidies
Provedor de dados: 31
Autores: Miao,   Ruiqing; Feng,   Hongli; Hennessy,   David A.
There have long been concerns that federal crop insurance subsidies may significantly impact land use decisions. It is well known that classical insurance market information asymmetry problems can lead to a social excess of risky land entering crop production. Our conceptual model shows that the problem will arise absent any information failures. This is because the subsidy is i) proportional to acres planted, and ii) greatest for the most production risky land. Using farm-level data, we follow this observation through to establish the implications of subsidies for the extent of crop production, with particular emphasis on U.S. regions where the cropland growth is likely to have marked adverse environmental impacts. Simulation results show that when...

The sugar industry is an important contributor to the South African (SA) economy, with average annual production estimated at 2.5 million tons of sugar. This study aims to quantify actual use of management instruments by a sample of commercial sugarcane farmers in KwaZulu-Natal (KZN) that are commonly associated with risk management, and uses factor analysis to investigate the extent to which these farmers bracket their management decisions. Data were obtained in 2006 via personal interviews of a stratified random sample of 76 large-scale sugarcane farmers in two separate mill-supply areas of KZN. Respondents were asked questions regarding risk-related management strategies, including diversification of on-farm enterprises, investments and management time....

Converting to organic farming in France: Is there a selection problem?
Provedor de dados: 31
Autores: Latruffe,   Laure; Nauges,   Celine.
Using a sample of French crop farms during the 1999-2006 period, we test whether less technically efficient farmers are more likely to engage in organic farming in order to benefit from conversion subsidies. Despite some limitations in our data, we find no evidence of such selection effect. On the contrary, our estimation results indicate that more technically efficient farmers are more likely to convert to organic farming. This finding is found to be robust to the method of calculation of efficiency scores, either parametric or non-parametric. This study also confirms that farm’s characteristics (education, farm size and legal status) and farmers’ practices under conventional farming do impact the probability of conversion to OF.

SOME TESTS OF THE ECONOMIC THEORY OF COOPERATIVES:  METHODOLOGY AND APPLICATION TO COTTON GINNING
Provedor de dados: 31
Autores: Sexton,   Richard J.; Wilson,   Brooks M.; Wann,   Joyce J.
Little progress has been made in testing the often conflicting hypotheses generated from theoretical research on cooperatives.  This paper addresses the deficiency by describing and applying (to California cotton ginning cooperatives) a methodology to test key hypotheses concerning (a) cooperatives’ price-output equilibrium, (b) allocative efficiency, and (c) utilization of capital inputs.  The empirical results (a) are consistent with predictions from the game theory model of cooperative behavior, (b) reject the null hypothesis of absolute allocative efficiency, and (c) indicate absolute overutilization of capital inputs among the sample cooperatives.

ESTIMATION OF DEMAND FOR WHEAT BY CLASSES FOR THE UNITED STATES AND THE EUROPEAN UNION
Provedor de dados: 31
Autores: Mohanty,   Samarendu; Peterson,   E. Wesley F.
This study estimates demand for wheat differentiated by classes using a dynamic AIDS model for the United States and the European Union (EU). The results suggest that imported wheat is more price responsive than domestic wheat in the U.S. market but not in the EU market. This may suggest that the Canadian policy that reduces prices of Canadian wheat in the U.S. market or U.S. export subsidies that raise prices of U.S, wheat could be expected to give rise to substantial substitution of Canadian for U.S. wheat. It is also found that in the EU, complementary relationships exist between spring and other wheat groups, This complementary relationship between the lower and higher quality wheat in the EU is not surprising because EU millers blend cheaper wheat...

This paper investigates the determinants of farm households‟ participation in export cropping and the impact of export cropping on household welfare, using cross-sectional data obtained from the Ghanaian living standards survey 2005-6. Given the problem of selectivity bias that arise when households self-select into export cropping, we employ the full information maximum likelihood approach to analyze the participation decision, and generalized propensity matching approach to examine the welfare impacts of participation. The empirical results indicate that farmers facing lower transport costs and having better access to credit facilities are more likely to participate in export cropping. Estimates of the welfare impacts of export cropping generally reveal...

Are Corn and Soybean Trend Yields Changing in Illinois?
Provedor de dados: 31
Autores: Sheppard,   Jessica.
Crop yields are influenced by a complex combination of factors, including weather, seed genetics, soil quality, and production management. Regardless, yields still tend to show a general trend over time, which is referred to as the “trend yield.” There has been much debate over whether improved technology has caused trend yields to change in recent years. Many experts believe recent corn yield increases were caused by advancements in biotechnology for seed genetics. It has been suggested that a lack of research on soybean genetics has led to a plateau in the soybean trend yield. It has been widely accepted that these new trends began in the mid-1990s and that they should be used for estimating future yields. However, weather should be taken into...

Since the 1940s, kenaf has been viewed as a potential source of fiber, mainly for newsprint and high quality paper. Kenaf research has once again risen to the forefront due to the recent USDA tobacco buyout. Many states and farmers dependent upon tobacco revenues have been seeking alternative crops for a number of years. This study seeks to expand the current literature by examining the economic feasibility of growing kenaf within three counties in Tennessee. Nitrogen meta-yield response functions for kenaf and four traditional crops were developed for 30 soils through crop growth simulation modeling and used to compare optimal crop budgets for each soil. Results reveal that kenaf would not compete favorably with traditional crops on any soil at prices...

Dry bean prices, as received by the grower and the dealer, were analyzed for four different production regions, and for two of the major varieties grown in the US.  The dry bean price series were not stationary.  Prices for each variety were cointegrated across the production regions and between grower and dealer markets.  However causality tests failed to show the dominant regional variety as the price leader.  Further, prices of the two varieties were not cointegrated, which indicated that growers would benefit from growing more than one variety at the same time.

Autores: Magnier,   Alexandre; Kalaitzandonakes,   Nicholas G.; Miller,   Douglas J.
The purpose of this study is to evaluate potential changes in the length of product life cycles in the US seed corn industry. We use the observed survival time on the market for hybrids sold during 1997-2009 to conduct a survival analysis. Our empirical results show that the average lifetimes of conventional and biotech corn hybrids have decreased over the last twelve years at similar rates and that the rate of decline in the life cycle length increased since 2004. We also find that the shorter product life cycles are closely linked to the accelerated levels of biotech product innovation in the US seed corn industry observed over the period of the analysis.

Optimal Coverage Level Choice with Individual and Area Plans of Insurance
Provedor de dados: 31
Autores: Bulut,   Harun; Collins,   Keith J.; Zacharias,   Thomas P.
We theoretically examine a farmer’s coverage demand with area and individual insurance plans as either separate or integrated options. The individual and area losses are assumed to be imperfectly and positively correlated. With actuarially fair rates, the farmer will fully insure with the individual plan and demand no area insurance regardless of the plans being separate or integrated. Under separate plans, free area insurance and the fair rate for individual insurance, area insurance replaces a portion of individual insurance demand. Under integrated plans, free area insurance, and the fair rate for individual insurance, the farmer will over-insure with individual plan and demand additional area insurance.

The higher commodity prices provide windfall profits to producers of affected crops who did not need the banned pesticide, while those producers who were previous users of the banned pesticide may gain or lose, depending on price elasticities of demand and supply. Increased imports may dampen consumer prices and reduce previous gains made by some producers. A crop-by-crop phase-out, based on economic effects in place of an immediate ban on all affected crops, could reduce the adverse effects on consumers, producers, and the balance of trade, while still achieving many of the human health and environmental benefits of an immediate total ban of all...

ASSESSING THE IMPACT OF CLIMATE CHANGE ON AGRICULTURE IN GERMANY - A RICARDIAN ANALYSIS
Provedor de dados: 31
Autores: Aurbacher,   Joachim; Lippert,   Christian; Krimly,   Tatjana.
To assess the impact of climate change on agriculture in German districts, a Ricardian analysis accounting for spatial autocorrelation is used. The analysis relies on land rental prices from agricultural statistics and climate data from the network of German weather observation stations. The results of the cross-sectional analysis show a significant correlation between land rents and increasing mean temperatures, as well as (except for East Germany) a significant increase of land rents along with declining spring precipitation. Next, climate data from the regional climate model REMO are used to calculate local land rent changes under different IPCC scenarios for a time horizon between 2011 and 2040. The overall result is an increase in land rents which...

GMOs: Prospects for Increased Crop Productivity in Developing Countries
Provedor de dados: 31
Autores: Evenson,   Robert E.
Genetically Modified Crops (GMO foods) have been widely available to farmers since 1996. The Gene Revolution, based on recombinant DNA (rDNA) genetic engineering techniques, is seen by proponents as both supplanting Green Revolution varieties, based on conventional plant breeding techniques, and potentially enabling “disadvantaged” production environments, unreached by Green Revolution varieties to achieve productivity improvements. This paper argues that the private firms supplying GM crop products have generally had little interest in selling products in disadvantaged production environments. The paper also argues that present rDNA techniques allow only static gains from specific “trait” improvements. But these GM products can be installed on Green...

Feasible Fumigant-Herbicide System Alternatives to Methyl Bromide for Bell Pepper Producers
Provedor de dados: 31
Autores: Byrd,   Mark M.; Escalante,   Cesar L.; Fonsah,   Esendugue Greg; Wetzstein,   Michael E.
With the current methyl bromide (MeBr) system for producing Georgia’s peppers being phased out, alternative fumigant and herbicide systems for producers are analyzed. Using stochastic dominance analyses, two alternatives exceeding MeBr’s yield and financial efficiency were identified. A programming model, incorporating simulation-optimization techniques, generated optimal production and financial plans. Results indicate potential economic viability under alternative systems vis-à-vis the traditional MeBr production system. The Telone II and Chloropicrin combination with Metham potassium may offer a viable substitute for MeBr.

WELFARE IMPLICATIONS OF INTRODUCING BIOTECH TRAITS IN A MARKET WITH SEGMENTS AND SEGREGATION COSTS: THE CASE OF ROUNDUP READY® WHEAT--SUMMARY
Provedor de dados: 31
Autores: Wilson,   William W.; DeVuyst,   Eric A.; Koo,   Won W.; Taylor,   Richard D.; Dahl,   Bruce L.
Roundup Ready® Wheat (RRW) was one of the first genetically modified (GM) traits for the wheat sector and was under review by regulatory agencies in the United States and Canada when Monsanto withdrew it from further consideration.  There are a multitude of issues associated with the ex ante evaluation of this decision.  These include market acceptance and segregation, as well as the varying sources of cost savings and productivity gains.  In this article, we develop a spatial partial equilibrium model of the higher-protein hard wheat market and assess the changes in the distribution of welfare associated with release and adoption of RRW.   It incorporates segments for GM aversion in each market and segregation costs for each segment.  Major conclusions...

Fiji's Sugar Woes: The Challenge of the Land Tenure System, Ethnicity and the Erosion of EU Sugar Preferences
Provedor de dados: 31
Autores: Mahadevan,   Renuka.
The non-renewal of land leases since 1997 and the impending withdrawal of the European Union’'s sugar preferences in 2007 have created major uncertainties in Fiji’'s sugar industry. In the context of this troubled environment, this paper examines the impact of various socio-economic factors on the viability of the industry by focusing on farm efficiency in sugar cane production. It was found that, in general, farmers were inefficient and produced 25% less than their potential output. Among the farm inputs, land (labour) was relatively the most (least) efficiently used input. Empirical evidence also suggests that the more productive Indian farmers rather than the natives be left to farm cane and that large scale farming should be seriously considered by...

A Dynamic Optimisation Model of Weed Control
Provedor de dados: 31
Autores: Jones,   Randall E.; Cacho,   Oscar J.
It is argued in this paper that static approaches to weed management, where the benefits and costs are only considered within a single season, are inappropriate for assessing the economic benefits of weed control technologies. There are carryover effects from weed management as weeds that escape control in one season may reproduce and replenish weed populations in following seasons. Consequently, it is appropriate to view weed control in the context of a resource management problem where the goal is to determine the optimal inter-temporal level of weed control that maximises economic benefits over some pre-determined period of time. A dynamic optimisation model for weed control is presented. Using the tools of comparative static analysis and Pontryagin's...

Selective vs. Broad-Spectrum Pesticides: When Do Private Decisions Differ from Socially Optimal Decisions?
Provedor de dados: 31
Autores: Grogan,   Kelly A.; Goodhue,   Rachael E.
This paper examines the spatial externalities of conventional and organic pest control methods to determine if, and how, the two types affect each other. These interactions make the problem more complicated than the usual analysis of a single externality. The numerical simulation model includes one organically managed and one conventionally managed field. One pest and one predator of the pest move between the two fields over five seasons. In each season, the conventional grower has the option of applying a broad-spectrum pesticide that kills the predator a selective pesticide that has no adverse effects on the predator but is either more expensive or less effective than the broad-spectrum pesticide. The organic grower can apply an organic pesticide,...

INSURING AGAINST LOSSES FROM TRANSGENIC CONTAMINATION
Provedor de dados: 31
Autores: Ripplinger,   David G.; Hayes,   Dermot J.; Lamkey,   Kendall R.
Concerns about contamination of the food supply and the financial losses that would result have limited the promise of certain genetically engineered plants. This article addresses the situation by constructing an insurance pricing model to protect against those losses.  The model first estimates the physical dispersal of corn pollen subject to a number of parameters.  This physical distribution is then used to calculate the premium for fair valued insurance that would be necessary to destroy contaminated fields.  The flexible framework can be readily adapted to other crops, management practices, and regions.

The Impact of NAFTA on Agricultural Commodity Trade: A Partial Equilibrium Analysis.
Provedor de dados: 31
Autores: Naanwaab,   Cephas B.; Yeboah,   Osei-Agyeman.
This paper examines the effects of the North American Free Trade Agreement on agricultural commodity trade using extensive data.  The data cover agricultural exports and imports between the U.S. and NAFTA partners over the extended period of 1989-2010.  The commodities covered in our analyses include; corn, soy bean, cotton, wheat, fresh vegetables, poultry, dairy products, and red meats.  Since the signing of the agreement, U.S. total agricultural commodity trade with NAFTA members has increased three-fold from $18 billion in 1994 to $61 billion in 2010.  A partial equilibrium model, in which we derive each trading partner's excess demand and excess supply, is used to study the impact of NAFTA on trade, controlling for other trade-inducing variables such...

Wheat Diversity and Productivity in Indian Punjab After the Green Revolution
Provedor de dados: 31
Autores: Smale,   Melinda; Singh,   Joginder; Di Falco,   Salvatore; Zambrano,   Patricia.
The Punjab of India is an historical source of key wheat genetic resources in national and global plant breeding, and a focus of concerns about the abandonment of local varieties during the Green Revolution. Much of the wheat area in Punjab was already planted with earlier products of modern plant breeding programs when the Green Revolution began. These cultivars were more genetically similar and less productive than the semi-dwarf wheat varieties that succeeded them. We define, summarize and test indices of variety change and genetic diversity for the modern wheat varieties released and grown in Indian Punjab during the post-Green Revolution period. The first is the area-weighted average of varieties grown, which measures the rate of variety change,...

Natural endowments, production technologies, and the quality of wines in Bordeaux. Is it possible to produce wine on paved roads?
Provedor de dados: 31
Autores: Gergaud,   Olivier; Ginsburgh,   Victor.
We study whether quality assessments made by wine experts and by consumers (based on prices obtained at auction between 1980 and 1992), can be explained by variables describing endowments (land characteristics, exposures of vineyards) and technologies (from grape varieties and picking, to bottled wines). However, since technological choices are likely to depend on endowments, the effects can only be identified using an instrumental variables approach. We show that technological choices affect quality much more than natural endowments, the effect of which is negligible.

This report evaluates the U.S. and world wheat markets for the 2003-2013 period using the Global Wheat Policy Simulation Model.  This analysis is based on a series of assumptions about general economic conditions, agricultural policies, weather conditions, and technological change.  Both the U.S. and world wheat economies are predicted to improve for the next 10 years.  World demand for both common and durum wheat are expected to grow faster than world production, resulting in gradual increases in prices of the wheat varieties.  However, the higher price levels experienced in 2002 and 2003 due to weather conditions will not be maintained in the short-term.  World trade volumes of both classes of wheat are expected to expand, but trade volume of durum wheat...

Autores: Frisvold,   George B.; Bicknell,   Kathryn; Bicknell,   Ross.
The objective of this research is to undertake an ex ante economic analysis of basic scientific research that aims to identify the gene(s) that control apomictic reproduction, with the ultimate aim of transferring the characteristic into commercially important crops. This paper reports very preliminary results, using the introduction of apomixis into rice as a case study. Apomixis is a natural, asexual method of plant reproduction resulting in offspring that are genetically identical to the mother plant. Apomixis promises to revolutionize plant breeding by providing a system for crop improvement that allows any desired variety, including hybrids, to breed true. This ability will make both breeding and seed production more efficient. It offers the...

Economics in plant breeding: A case focusing on doubled haploid technology
Provedor de dados: 31
Autores: Pluske,   Johanna M.
With increasing choices in technologies, decision makers responsible for allocating resources in plant breeding programs can benefit from using bioeconomic models. This paper illustrates how such a model works when doubled haploid technology is incorporated into a hypothetical lupin breeding program. The results derived from the model are presented in terms of seed prices required to achieve an 8% return on research. Doubled haploid technology will be used in a breeding program providing the price for seed produced using this technology is less than the seed market price and the estimated price for seed produced using alternative technologies.

Are there customary rights to plants? An inquiry among the Baganda (Uganda), with special attention to gender
Provedor de dados: 31
Autores: Howard,   Patricia L.; Nabanoga,   Gorettie.
Debates around Common Property Resources and Intellectual Property Rights fail to consider traditional and indigenous rights regimes that regulate plant resource exploitation, establish bundles of powers and obligations for heterogeneous groups of users, and create differential entitlements to benefits that are related to social structures. Such rights regimes are important to maintaining biodiversity and to human welfare; failing to recognize them presents dangers. The case study investigates the gendered nature of informal rights to selected tree and plant species that are distinct from, but related to, customary rights to land and trees, and are embedded in cosmology and social norms.

Sources of Productivity Growth in Wheat: A Review of Recent Performance and Medium- to Long-Term Prospects
Provedor de dados: 31
Autores: Rejesus,   Roderick M.; Heisey,   Paul W.; Smale,   Melinda.
Sources of yield growth in wheat are investigated based on a stylized framework of technical change. Evidence suggests that the relative contribution of input intensification to yield growth has diminished in recent years and is likely to continue to decline in the future. One potential source of yield growth in wheat during the medium to long term is improved efficiency of input use, rather than input intensification, through sustainable wheat production practices rather than pure input increases. Other large gains could be made with continuous adoption of newer and better modern varieties based on advances in wheat breeding. Wide crossing and biotechnology could improve the stability of wheat yields in the intermediate term; their long-term impact on...

Introducing deficit irrigation crop techniques derived by crop growth models into a Positive Mathematical Programming model
Provedor de dados: 31
Autores: Severini,   Simone; Cortignani,   Raffaele.
There is a growing policy pressure to reduce water use in agriculture when this generates sufficiently large environmental benefits and increases the well-being of other water users. Several analysis investigate farmers’ response to water policy by means of mathematical programming models including Positive Mathematical Programming (PMP). The originals PMP methods refer only to activities observed in the reference period. However, under the pressure of new water policies, farmers can adjust not only their cropping patterns but also the irrigation techniques they use. In particular, they could introduce water deficit irrigation crop techniques that were not profitable in past conditions. This paper proposes an extension of the Röhm and Dabbert approach...

Using 23 years of data (1978-2000), this study examines seven vertically integrated sugar beet plants representing three different companies in the United States. The objective of this research is to identify the marginal costs of producing sugar beets for vertically integrated sugar beet processors as a way of determining the cost savings from higher quality sugar beets. In doing so, we account for quality differences in the sugar beet input that are used to manufacture the refined sugar output. The results quantify links between high quality sugar beets and lower processing costs.

The growing importance of economic factors in farmers’ decision to go organic has raised interest in characterizing the economic behavior of organic versus conventional farms. Published analyses so far have not considered differential uncertainties and farmers’ risk preferences between conventional and organic practices when comparing these techniques. Our article attempts to assess this issue. We use a model of farmer decision under risk to analyze the differential values between Spanish COP organic and conventional farms and to assess the incentives for adoption of organic practices. Results show that organic and conventional farms do have different abilities to control production risk as well as different risk preferences. Organic price premiums and...

The rice stink bug is a major pest of rice in Texas, causing quality related damage.  The previous threshold used for assisting in rice stink bug spray decisions lacked flexibility in economic and production decision variables and neglected the dynamics of the pest population.  Using stochastic dynamic programming, flexible economic thresholds for the rice stink bug were generated.  The new thresholds offer several advantages over the old, static thresholds, including increased net returns, incorporation of pest dynamics, user flexibility, ease of implementation, and a systematic process for updating.

This paper investigates the determinants of rice seed variety choice in Indonesia with respect to a meta-profit function. Varietal choice is modeled as depending on the profitability of high yielding varieties of seed relative to traditional varieties of seed, the schooling of cultivators and factors associated with yield uncertainty and risk aversion. Careful attention is paid to the stochastic structure of the estimated simultaneous equations switching regimes model. The maximum likehood method applied to Indonesian farm-level data is complicated by endogenous regressors and heteroskedastic errors. Adoption of high yielding varieties was found to be positively associated with its relative profitability, the likelihood of flooding, quality of irrigation...

Spatio-temporal Risk and Severity Analysis of Soybean Rust in the United States
Provedor de dados: 31
Autores: Bekkerman,   Anton; Goodwin,   Barry K.; Piggott,   Nicholas E.
Soybean rust is a highly mobile infectious disease and can be transmitted across short and long distances.  Soybean rust is estimated to cause yield losses that can range between 1%-25%.  An analysis of spatio-temporal infection risks within the United States is performed through the use of a unique data set.  Observations from over 35,000 field-level inspections between 2005 and 2007 are used to conduct a county-level analysis.  Statistical inferences are derived by employing zero-inflated Poisson and negative binomial models.  In addition, the model is adjusted to account for potential endogeneity between inspections and soybean rust finds.  Past soybean rust finds and inspections in the county and in the surrounding counties, weather and overwintering...

Impact of Government Payments, Depreciation and Inflation on Investment Behavior in American Agriculture Sector Using Sample of Kansas Farms
Provedor de dados: 31
Autores: Ariyaratne,   Chatura B.; Featherstone,   Allen M.
A farm’s physical investment is affected by its fundamental q and by its financial situation, with the later comprising both the firm’s liquidity and its possibility of facing capital market imperfections. This study determines the effects of government payments, depreciation, and inflation on crop farm machinery and equipment investment behavior employing the Nonlinear Generalized Method of Moment (GMM) estimator to estimate the investment system. The magnitude of the lagged cash flows such as government payments, cash crop income, and grain income were largely responsible for determining farm investment behavior in the Kansas agriculture sector. An increase in lagged machinery and equipment depreciation and lagged farm motor vehicle and listed property...

Effects of participation in organic markets and farmer-based organizations on adoption of soil conservation practices among small-scale farmers in Honduras
Provedor de dados: 31
Autores: Wollni,   Meike; Lee,   David R.; Thies,   Janice E.
Conservation agriculture is often perceived to provide “win-win” outcomes for farmers leading to reduced erosion and off-site sedimentation, as well as improved soil fertility and productivity. However, adoption rates for conservation agriculture in many regions of the world remain below expected levels. This paper looks at the effect of organic markets in providing incentives for farmers to adopt soil conservation practices based on the willingness of consumers to pay a price premium for the use of sustainable production technologies. Farmer-based organizations may help farmers overcome information deficiencies with respect to production processes as well as consumer preferences. Based on original survey data from 241 small-scale farm households in...

Greenhouse Gas Emission Factor Module: Land Use in Rural New Zealand—Climate Version 1
Provedor de dados: 31
Autores: Hendy,   Joanna; Kerr,   Suzi.
Several different New Zealand economic models produce measures of rural economic activity that have greenhouse gas implications. For climate change analysis, models need to translate economic activity into greenhouse gas emissions. This document estimates functions and creates projections for land-use related greenhouse gas emissions per unit of economic activity that are simple; are based on readily available data and strong science; are consistent with the national inventory in 2002; evolve so that implied net emissions approximately match past inventory totals (1990–2002); and can be linked easily to a variety of models so they can be used in simulations. We estimate dynamic greenhouse gas emission functions for five land uses: dairy, sheep, beef,...

The Marketing Performance of Illinois and Kansas Wheat Farmers
Provedor de dados: 31
Autores: Dietz,   Sarah N.; Aulerich,   Nicole M.; Irwin,   Scott H.; Good,   Darrel L.
The purpose of this paper is to analyze the marketing performance of wheat farmers in Illinois and Kansas over 1982–2004. The results show that farmer benchmark prices for wheat in Illinois and Kansas fall in the middle third of the price range about half to three-quarters of the time. Consistent with previous studies, this refutes the contention that Illinois and Kansas wheat farmers routinely market the bulk of their wheat crop in the bottom portion of the price range. Tests of the average difference between farmer and market benchmark prices are sensitive to the market benchmark considered. The marketing performance of wheat farmers in Illinois and Kansas is about equal to the market if a 24- or 20-month market benchmark is used, slightly above the...

Technical efficiency analysis and decomposition of productivity growth of Spanish olive farms
Provedor de dados: 31
Autores: Lambarraa,   Fatima; Serra,   Teresa; Gil Roig,   Jose Maria.
The concept of technical efficiency is critical to measuring the firm performance, determining the degree of innovative technology adoption and the overall production efficiency. Traditionally, technical efficiency has been measured as the ratio of observed output to maximum feasible output. Stochastic frontier models have been widely utilized to assess this issue. Our research evaluates technical efficiencies in the Spanish olive sector. Specifically, the main objective of this study is to estimate a stochastic frontier production model by using a farm- level panel of data. The non- negative technical efficiency effects are assumed to be a function of firm- specific variables. A sample of Spanish farms observed from 1999 to 2002 is obtained from the FADN...

ECONOMIC AND TECHNICAL ANALYSIS OF ETHANOL DRY MILLING: MODEL DESCRIPTION
Provedor de dados: 31
Autores: Dale,   Rhys T.; Tyner,   Wallace E.
Ethanol, the common name for ethyl alcohol, is fuel grade alcohol that is predominately produced through the fermentation of simple carbohydrates by yeasts.  In the United States, the carbohydrate feedstock most commonly used in the commercial production of ethanol is yellow dent corn (YDC).  The use of ethanol in combustion engines emits less greenhouse gasses than its petroleum equivalent, and it is widely hoped that the increased substitution of petroleum by ethanol will reduce US dependence on imported oil and decrease greenhouse gas emissions.  Production of ethanol within the United States is expected to double, from 3.4 billion gallons in 2004, to about seven billion gallons in the next five years.    Two processes currently being utilized to...

WHEAT CHARACTERISTIC DEMAND AND IMPLICATIONS FOR DEVELOPMENT OF GENETICALLY MODIFIED GRAINS
Provedor de dados: 31
Autores: Janzen,   Edward L.; Mattson,   Jeremy W.; Wilson,   William W.
Agricultural biotechnology is advancing rapidly and is embracing all major crops.  The adoption of genetically modified corn, soybeans, and cotton have reached high levels in the United States.  Wheat is the next major crop confronting the biotechnology issue, but no commercial varieties of genetically modified (GM) wheat have been released yet.  Primary opportunities for GM developments in wheat center around improvements that meet consumer and end-user needs/issues in addition to meeting producer efficiencies.  Developers and proponents of GM wheat must focus on education of consumers and restoration of worldwide confidence in the regulatory systems.  The most desired wheat quality trait among millers and bakers is the assurance of consistent quality.

Developments in the Indian seed industry and their impact on access and use of commercial seed by farmers have been examined. Various types of seed systems such as hybrids, self-pollinated crops, vegetatively propagated crops, crops with high seed volume, etc have been analysed. It has been shown that the commercial seed markets for hybrids are well developed, but these need improving flow of information to farmers and effective regulation of unscrupulous traders, etc. There are significant changes in terms of seed regulations, management of GM crops and protection of intellectual property. Since all these regulations are mutually enforcing, there is a need for developing institutional capacity for their enforcement, as well as flexibility to learn from...

Neoclassical consumer theory and genetically modified food
Provedor de dados: 31
Autores: Kaye-Blake,   William.
Three axioms underpin consumer choice in neoclassical theory: weak order, independence, and continuity. Two of these axioms may not hold, however, for consumers’ choices regarding genetically modified (GM) food. Consumers may evaluate product attributes differently depending on whether the food is GM or not, violating attribute independence. Some consumers may not want GM food at all, violating continuity. The axioms were empirically investigated with a choice experiment survey. The paper discusses evidence of violations of both independence and continuity, as well as a non-neoclassical approach to modelling consumer choice.

Autores: Miranowski,   John A.; Jensen,   Helen H.; Batres-Marquez,   S. Patricia; Ishdorj,   Ariun.
An important dimension of product differentiation and segregation for specialty crops is the added handling and transaction costs incurred. Some forms of business organization may realize lower costs of providing such services, and if specialty crop production is growing relative to commodity production, these two factors may have implications for industry structure. We use data from an Iowa grain handling survey to test hypotheses developed in the non-empirical transaction-costs literature with respect to organizational and financial governance of cooperatives and private and corporate firms. Preliminary results are discussed with respect to business organizations, added costs, investments, crops, and contracting.

A theoretical optimal hedging model is developed to determine potential demand from Australian farmers for a hedging tool to remove the economic consequences of climate related variability in wheat yield. In the past, financial instruments have been developed to hedge price risk on capital markets; however, in more recent times new financial instruments, weather derivatives, have been developing that hedge the volumetric risk associated with unfavourable weather. Weather derivatives have the ability to effectively hedge weather related volume risk for the agricultural, mining, energy and manufacturing industries, while also providing a risk management tool for construction firms and special events organisers, although there are still many hurdles to...

Greenhouse Gas Mitigation through Energy Crops in the United States with Implications for Asian-Pacific Countries
Provedor de dados: 31
Autores: Schneider,   Uwe A.; McCarl,   Bruce A.
Agriculture-based biofuels have the potential to replace fossil fuels, thereby offsetting greenhouse gas emissions. We estimate emission abatement supply curves from energy crops switchgrass, hybrid poplar, and willow under a wide range of sectorwide greenhouse gas emission reduction incentives in U.S. agriculture. The Agricultural Sector Model employed captures market interactions of biofuel production with traditional agricultural production and with alternative emission mitigation strategies. U.S. results suggest an increasing importance of biomass-based electricity for carbon mitigation incentives above an economic threshold of $50 per ton. At incentive levels of $170 per ton and higher, emission offsets from energy crops provide the highest net...

Household Level Financial Incentives to Adoption of Conservation Agricultural Technologies in Africa
Provedor de dados: 31
Autores: Haggblade,   Steven; Tembo,   Gelson; Donovan,   Cynthia.
Although several studies have been conducted to determine the viability of conservation agriculture in Sub-Saharan Africa, almost all such studies are fragmented – often country specific – and with undue emphasis on output effects. However, assessment of the attractiveness of these technologies in Sub-Saharan Africa requires a detailed case-by-case comparison of changes in output and input costs and benefits. This paper reviews a set of responses known collectively as “conservation” or “sustainable” agriculture. Though definitions vary, these technologies typically involve agricultural management practices that prevent degradation of soil and water resources and thereby permit sustainable farm productivity without environmental degradation.

Autores: Cochran,   Rebecca L.; Larson,   James A.; Roberts,   Roland K.; Tyler,   Donald D.
Soil acidity and cotton yields are influenced by cover crop, nitrogen, and tillage method.  Applying half the recommended lime rate may be possible without reducing cotton yields.  Using a nitrogen intensive cover crop and applying less nitrogen should mitigate the effects on soil acidity and yields.

Food Pricing Policy and Rural Poverty: Insights from Maize in Kenya
Provedor de dados: 31
Autores: Mghenyi,   Elliot W.; Jayne,   Thomas S.
This study estimates the effects on poverty resulting from maize price changes associated with the operations of the maize marketing board in Kenya. We consider both supply and demand responses and the accompanying adjustments in rural labor markets in estimating a second order approximation to equilibrium income changes. We then use stochastic dominance techniques to generate poverty rankings between the distribution of income with the effects of the government marketing operations and the distribution of counterfactual incomes. This approach effectively addresses concerns regarding the sensitivity of poverty estimates to the type of poverty measure used. Results indicate that the price-elevating effects of government maize marketing operations have...

The Effects of Market Reform on Maize Marketing Margins in South Africa: An Empirical Study
Provedor de dados: 31
Autores: Traub,   Lulama Ndibongo; Jayne,   Thomas S.
This paper determines the effect of market reform and price decontrol on the size of maize milling/retail margins in South Africa. Regression models of monthly milling/retail margins are run over the period May 1976 to September 2003. To assess the robustness of our findings, we estimate several different model specifications for representing structural change, vary the sample period to examine the sensitivity of findings to unusual weather and market conditions in the region during the 2001-2003 period, and use different estimation techniques, OLS with Newey-West robust estimators and Feasible General Least Squares. In virtually all models, the results indicate that real maize milling/retailing margins in South Africa have increased since the market...

Autores: Marra,   Michele C.; Gould,   Thomas D.; Porter,   Gregory A.
A model is developed to determine the minimum weed population where a decision to apply a postmergence herbicide would be profitable.  The economic threshold model accounts for changing economic conditions, the effect of weeds on crop quality, the effect of multiple weed species on yield and quality, and uncertainty about spraying period length.  The model is uncomplicated enough for microcomputer or programmable calculator applications. An example of weed threshold calculations for round white potatoes is given.

Optimal Coverage Level Choice with Individual and Area Plans of Insurance
Provedor de dados: 31
Autores: Bulut,   Harun; Collins,   Keith J.; Zacharias,   Thomas P.
We theoretically examine a farmer’s coverage demand with area and individual insurance plans as either separate or integrated options. The individual and area losses are assumed to be imperfectly and positively correlated. With actuarially fair rates, the farmer will fully insure with the individual plan and demand no area insurance regardless of the plans being separate or integrated. Under separate plans, free area insurance and the fair rate for individual insurance, area insurance replaces a portion of individual insurance demand. Under integrated plans, free area insurance, and the fair rate for individual insurance, the farmer over-insures using both area and individual plans.

A PROPOSAL FOR EFFECTIVE TECHNOLOGY TRANSFER
Provedor de dados: 31
Autores: Wilson,   Maurice.
The paper examines the performance of the agricultural sector over the 10 year period 1995-2004. Indicators suggest that investments in Agricultural Research and Development (used as a proxy for the quantum of technology generated) have had little impact on agricultural production.  In this regard, an assumption is made that technology generated has neither been adequately transferred nor adopted. Within the above context a holistic model for effective technology generation has been presented.  It is argued that effective technology generation is market driven technology is more likely to be transferred and adopted by agribusiness entities. To implement this process, strategic alliances should be forged in order to address resource limitations. The entire...

Towards the measurement of the impacts of improving research capacity: an economic evaluation of training in wheat disease resistance
Provedor de dados: 31
Autores: Brennan,   John P.; Quade,   Kathryn J.
It is notoriously difficult to assess the economic value of research aimed at improving research capacity, particularly for the human capital component of research capacity. In this paper, a framework is developed and an analysis is undertaken of the value of training for scientists in wheat rust resistance. The value of improving human capital is assessed through a framework based on marginal analysis of the improvement in productivity outcomes flowing from the increased capacity. On that basis, the value of programs to build human capacity through training or further education can be estimated. Although such estimates are necessarily qualified, they provide a basis for quantifying the value of building research and development capacity.

Impact of Zero Tillage in India's Rice-Wheat Systems
Provedor de dados: 31
Autores: Laxmi,   Vijay; Erenstein,   Olaf; Gupta,   Raj K.
To date, the most widely adopted resource conserving technology (RCT) in the Indo-Gangetic Plains (IGP)has been zero-tillage (ZT) for wheat after rice, particularly in India. This report reviews and synthesizes the experience with zero tillage in the Indian IGP. Zero tillage of wheat after rice generates significant benefits at the farm level, both in terms of significant yield gains (6–10%, particularly due to timelier planting of wheat) and cost savings (5–10%, particularly tillage savings). These benefits explain the widespread interest of farmers and the rapidity of the diffusion across the Indian IGP, further aided by the wide applicability of this mechanical innovation. The study  subsequently reports on the findings of village-level focus-group...

Four environments with contrasting potential for agricultural productivity and infrastructure development were identified in Guanajuato State, Mexico, to test hypotheses about the relationship of maize biological diversity to the region's potential for agricultural productivity and infrastructure development. Samples of all types of maize grown by a random sample of farmers were collected from each environment. The maize samples were classified by race, racial mixture, or type of 'creolized' or improved variety. Landraces were the dominant maize class in all four environments; the use of improved varieties was negligible. Several diversity indices were calculated, and no statistically significant differences were apparent between the environments with the...

Fresh Grapefruit Supply-Chain Adjustments: Consolidation in Produce Packing?
Provedor de dados: 31
Autores: Thornsbury,   Suzanne; Davis,   Kathy J.; Ward,   Ronald W.
This study evaluates long-term structural adjustments in fresh grapefruit packing under aggregate market pressures, including those from retail concentration. While individual firms enter and exit, Markov-model results are indicative of an industry near equilibrium with little expectation of change in the distribution of firm sizes given existing patterns of sector adjustment. Estimation of Lorenz curves and corresponding Gini coefficients fully support Markov analysis findings. Lags in the packing sector adjustment process in the face of sweeping forces of change in fresh produce markets are likely to put this sector at a relative disadvantage within the supply chain.

Fruit production forecasting by neuro-fuzzy techniques
Provedor de dados: 31
Autores: Atsalakis,   George S.; Atsalakis,   Ioanna G.
Neuro-fuzzy techniques are finding a practical application in many fields such as in model identification and forecasting of linear and non-linear systems. This paper presents a neuro-fuzzy model for forecasting the fruit production of some agriculture products (olives, lemons, oranges, cherries and pistachios). The model utilizes a time series of yearly data. The fruit forecasting is based on Adaptive Neural Fuzzy Inference System (ANFIS). ANFIS uses a combination of the least-squares method and the backprobagation gradient descent method to estimate the optimal food forecast parameters for each year. The results are compared to those of an Autoregressive (AR) model and an Autoregressive Moving Average model (ARMA).

Demographic and Management Factors Affecting the Perceived Benefit of Winter Cover Crops in the Southeast
Provedor de dados: 31
Autores: Bergtold,   Jason S.; Duffy,   Patricia A.; Hite,   Diane; Raper,   Randy L.
The inclusion of cover crops in cropping systems brings both direct and indirect costs and benefits. Farmers will adopt and continue to utilize cover crops in their production systems as long as the perceived benefit of using cover crops (e.g. increased yield, higher profits, and improved soil productivity) is positive.  The perceived benefits, while partially based on actual changes, may be influenced by demographic, economic and management factors. The purpose of this paper is to examine the demographic and management factors affecting the perceived benefit, in terms of improved crop yield, of using winter annual cover crops. A tobit model is estimated using survey data of Alabama farmers examining cover crop use and management. The model examines the...

Agricultural biodiversity is an environmental resource. Much of the agricultural biodiversity remaining in situ today is found on the semi-subsistence farms of poorer countries and the small-scale farms or home gardens of more industrialized nations. The traditional small farms of Hungary are labelled "home gardens" as a reflection of their institutional identity during the collectivisation period. Homesteads managed with family labor, they continue to serve essential food security and diet quality functions during economic transition. Home gardens contribute to the preservation of rural settlements and cultural heritage, and they contain relatively high levels of several components of agricultural biodiversity. The role of home gardens in the...

Global welfare effects of transgenic sugar beet
Provedor de dados: 31
Autores: Dillen,   Koen; Demont,   Matty; Tollens,   Eric.
Although the EU is still in a quasi moratorium stage concerning GM crops, doors for GM crops in the sugar industry seem to open. Herbicide tolerant sugar beet could mean a boost for the sugar beet sector. The ex ante impact assessment shows a created welfare of €15 billion during 1996-2014. The rule of thumb found in ex post impact studies of a sharing out between downstream and upstream sector of 2/3 versus 1/3 is seems to be applicable to this case as well. The sugar beet sector and consumers worldwide are the winners while cane growers lose due to technology eroded world prices. The reform of the EU Common market organization for sugar in 2006 seems to create an incentive for innovation to efficient European sugar producers. Crowding out of inefficient...

In despite of the several advantages for exporting ground and roasted coffee instead of green coffee, namely employment and value gains, there are many limitations to the private efforts. Effective attempts have been discouraged by large and stable national market, high risks associated to the international market, and a frightening bureaucracy. Even so, some progress has been reported in recent years as is shown in this paper, based on interviews with Brazilian export agents, industries and cooperatives. Some restrictions are inherent to the enterprises, such as managerial questions and innovation aptitude, while others are systemic. Suggestions to improve processed coffee exports are presented.

Economic Impact of a Proposed AGI Means Test on Representative Crop Farms
Provedor de dados: 31
Autores: Richardson,   James W.; Outlaw,   Joe L.; Raulston,   J. Marc.
The Administration has proposed revising the AGI means test for eligibility to farm program payments. The 2002 farm bill excludes producers from farm program payments (CCP, DP, and MLG/LDP) if their average adjusted gross income (AGI) for three preceding years exceeds $2.5 million and less than 75% of their AGI comes from farming, ranching or forestry operations. The revised means test would reduce the AGI cut-off to $200,000 and repeal the 75% exclusion. The purpose of this report is to estimate the impacts of the AGI proposal on average annual government payments and real net worth in 2014 for representative crop farms. The AFPC maintains a data base of 64 representative commercial family farms in major production regions across the United States. The...

Estimates of community preferences for preservation of natural land, derived from a choice modelling study, are used as input to a model of agricultural production in an optimisation framework. The trade‐offs between agricultural production and environmental protection are analysed using the sugar industry of the Herbert River district of north Queensland as an example. Spatially‐differentiated resource attributes and the opportunity costs of natural land determine the optimal trade‐offs between production and conservation for a range of sugar prices.

The Impact of Investments in Maize Research and Dissemination in Zambia Part I: Main Report
Provedor de dados: 31
Autores: Howard,   Julie A.; Chitala,   George M.; Kalonge,   Sylvester M.
Michigan State University (MSU) is currently assessing the impact of agricultural research on various commodities in seven African countries: Cameroon (maize, cowpea, sorghum), Kenya (maize, wheat), Malawi (maize), Mali (maize), Niger (sorghum, cowpea, millet), Uganda (oilseeds), and Zambia (maize). These countries were selected because they represent a variety of agro-ecological regions, and because their research systems have received significant levels of funding from USAID. The country studies undertaken by MSU are part of a series of research works recently commissioned to help USAID and the U.S. Congress analyze the effectiveness of aid given to strengthen national agricultural research systems in Africa. In Zambia, MSU collaborated with the Ministry...

PRODUCTION PLANNING AND INCOME VARIABILITY ANALYSIS FOR ALTERNATIVE SAGINAW VALLEY NAVY BEAN CROPPING SEQUENCES
Provedor de dados: 31
Autores: Marquez,   Jorge E.
Acreage allocation decisions by farmers have been identified as one of the causes of the decline in Michigan's navy bean production.  Growing navy beans in successive years or in short rotation with other crops that return little organic matter to the soil has been shown to adversely affect soil structure, depletion of organic matter, and increase disease and pest problems.  Furthermore, a large portion of the instability present in the quantity of navy beans produces, and therefore in prices and revenue, is directly related to variability in acreage allocation decisions of growers.  In consequence, the problem as it is seen in this paper is one of resource allocation decisions by farmers.  There is a need for defining a navy bean production strategy,...

Factor Input Demand Subject to Economic and Environmental Risk: The Case of Nitrogen Fertilizer in Corn Production
Provedor de dados: 31
Autores: Carriker,   Gordon L.
Nitrogen (N) fertilizer demand in relation to economic and environmental risks associated with N-fertilizer management are examined. Both nominal and environmental damage-adjusted net returns distributions are evaluated using stochastic dominance analysis. Results suggest that, in the absence of environmental risk, N demand becomes more elastic as farmers become more risk averse. When environmental risk is introduced to the decision-making process, N demand becomes even more elastic.

U.S. CORN MOVEMENTS, 1985: A PRELIMINARY REPORT OF DATA
Provedor de dados: 31
Autores: Fruin,   Jerry E.; Halbach,   Daniel Walter; Hill,   Lowell D.; Allen,   Albert J.
This paper presents the results of the corn portion of the 1985 grain flow survey and makes comparisons with 1977 when the previous survey was done.  The most significant change from 1977 was the increase in exports from the Pacific Northwest ports from 15 million bushels to over 290 million in 1985.  This was accomplished by an increase in rail shipments from Nebraska, Minnesota, and South Dakota.  The decline in European Economic Community demand reduced corn movements through the Great Lakes and Atlantic ports and, consequently, truck movements to those ports.  Trucks increased their share of domestic movements. The large 1985 corn crop and subsequent increase in stocks reduced the volume of interstate movements and the length of shipping distances....

AN ANALYSIS OF THE IMPACT OF A BAN OF METHYL BROMIDE ON THE U.S. WINTER FRESH VEGETABLE MARKET
Provedor de dados: 31
Autores: Deepak,   M.S.; Spreen,   Thomas H.; VanSickle,   John J.
This study evaluates the economic impact of a ban on methyl bromide on the U.S. winter fresh vegetable market for six major crops: tomatoes, green peppers, cucumbers, squash, eggplant, and watermelons. Florida is the primary domestic supplier of these products. Mexico and Texas are the competing suppliers of the five vegetable crops and peppers, respectively. Leontief technologies represent both monocrop and double-crop production systems; linear inverse demand functions represent four demand regions in the U.S. and Canada. By increasing production costs and reducing yields, a ban on methyl bromide decreases Florida's FOB revenues by 54% and increases those of Mexico by 65%. Price increases to U.S. fresh vegetable consumers range from near zero to over...

Adoption of a New Maize and Production Efficiency in Western Kenya
Provedor de dados: 31
Autores: Mignouna,   D.B.; Mutabazi,   K.D.S.; Senkondo,   E.M.; Manyong,   Victor M.
Declining yields of maize as a result of Striga infestation has necessitated a new technology known as Imazapyr-resistant maize (IRM) to contain the problem. As a result, research and development initiatives with substantial participation of the private sector to transfer this new technology to farmers have been made in western Kenya. This study therefore assesses the adoption of IRM variety and efficiency levels of farmers in western Kenya. A multi-stage sampling technique was used to select a total of 600 households from Nyanza and Western provinces for this study. Tobit model and stochastic production frontier analysis were the analytical methods. Results show that age, education, maize production gap, risk, contact with extension agents, lack of seeds,...

MINIMIZING FARM-TO-MILL COTTON CLEANING COST
Provedor de dados: 31
Autores: Bennett,   Blake K.; Misra,   Sukant K.
This study focuses on least-cost farm-to-mill cotton cleaning configurations employing survey, regression, and simulation techniques.  The resulting least-cost cotton cleaning configurations, employing standard textile technology, included the use of one lint cleaning in the ginning stage.  The use of a field cleaner in the harvesting stage was also found to be optimal with some variation based on the desired yarn quality.  Results of the study indicated that the optimal cleaning configurations were distinctly different from currently used practices, such that appropriate changes could save the cotton industry between $0.30 and $0.60 per bale of cotton, depending on the desired yarn quality.

The Regional Distribution of Farm-Level Impacts from Acreage Set-Asides
Provedor de dados: 31
Autores: Babcock,   Bruce A.
The question of whether the United States should once again authorize acreage setasides will be addressed now that Congress has decided to hold hearings about a possible early rewrite of farm policy. Questions about the impact of acreage set-asides on farm income and national policy goals will need to be answered. This paper takes an initial look at three pertinent questions: (1) What impact will acreage set-asides have on the prices of corn, soybeans, and wheat? (2) What would be the differential farm-level impacts of set-asides across regions? And (3) How might acreage controls work with existing marketing loans? A 10 percent reduction in corn, soybeans, and wheat would significantly raise prices in a one-year time frame. Over a three-year period,...

Malian farmers have been cultivating millet and sorghum for millennia, but they are slow to adopt and develop modern varieties because it is difficult to observe the difference in yields in their fields, given the challenging local growing conditions. Farmer participatory approaches are therefore recommended. This paper applies an instrumental variables method to survey data from Mali to evaluate the impacts of Diversity Field Fora, a type of farmer field school which aims to boost millet and sorghum yields by showing farmers how to manage diverse varieties. Impact indicators are expected and recalled millet and sorghum yields, the total number of unique attributes of millet and sorghum varieties stocked as seed, and the relative deprivation of the...

Stochastic maize production technology and production risk analysis in Dadar district, East Ethiopia
Provedor de dados: 31
Autores: Fufa,   B.; Hassan,   Rashid M.
A stochastic production technology that allows risk effects of factor inputs was estimated for maize farmers in Ethiopia. The results suggested that the promoted improved maize technology exhibits constant returns to scale whereas non-adopters use decreasing returns to scale technology. The study showed that timely planting is critical for maize yield stability among both adopters and non-adopters and suggests the importance of using oxen and higher efforts to achieve that. Nevertheless, the results showed that most of the factors under the control of the farmers do not offer powerful explanation to maize yield variability compared to natural factors such as rainfall, frost, pests and diseases.

Autores: Erraach,   Yamna; Sayadi,   Samir; Parra-Lopez,   Carlos.
Competitiveness and sustainability of the olive-oil sector are strongly associated with the satisfaction of customer demand and preferences towards quality, safety, and environmental issues. In product design and development, Quality Function Deployment (QFD) provides a comprehensive, systematic approach to ensure agrifood products meet or exceed customer expectations. QFD can be a powerful tool because it can reduce time to market, improve quality, and enhance customer satisfaction. Although QFD has been used in the food industry since 1987, no application has been found in the case of olive oil. In this study, after identifying customer needs or requirements of different attributes of quality olive oil, by a survey to 439 respondents to determine...

Determinants of the Speed of Adoption of Soil Fertility-Enhancing Technologies in Western Kenya
Provedor de dados: 31
Autores: Odendo,   Martins; Obare,   Gideon A.; Salasya,   Beatrice.
Most adoption studies have employed cross-sectional data in a static discrete choice modelling framework to analyze why some farmers adopt at a certain point in time. The static approach does not consider the dynamic environment in which the adoption decision is made and thus does not incorporate the speed of adoption and the effect of time-dependent elements in explaining adoption. The adoption speed of an innovation is important in various aspects. Based on data from a survey of a random sample of 331 smallholder households in western Kenya, this study investigated determinants of time to adoption of mineral fertilizer, animal manure and compost using Duration analysis. Results revealed that factors that influenced timing of the adoption varied by the...

MANAGING PHOSPHOROUS SOIL DYNAMICS OVER SPACE AND TIME
Provedor de dados: 31
Autores: Lambert,   Dayton M.; Lowenberg-DeBoer,   James; Malzer,   Gary L.
Understanding the relationship between soil fertility dynamics and crop response is conceptually appealing. Even more appealing is comprehension of the spatial and temporal heterogeneity of these connections over a production surface and across seasons. Knowledge of these interactions is complicated because nutrient carryover dynamics and crop response to inputs are determined simultaneously on the one-hand, and sequentially on the other. A second problem enters when crops are rotated, for example, in the corn-soybean system commonly practiced in the Corn Belt. This paper examines the nutrient carryover-crop response nexus using data from a corn-soybean, variable-rate nitrogen (N) and phosphorous (P) experiment conducted over five years. Site-specific corn...

FARMERS' DECISION PROCESSES AND ADOPTION OF CONSERVATION TILLAGE
Provedor de dados: 31
Autores: Westra,   John V.; Olson,   Kent D.
In a transect survey of crop residue levels in 1995 and 1996, two Minnesota counties had very different percentages of cropland with desired residue cover even though the soil types were similar.  To gain a better understanding of the reasons behind this difference, the farmers in these two counties were surveyed about their use or lack of use of conservation tillage practices.  A statistical logit analysis of survey responses showed farmers are more apt to adopt conservation tillage if they are larger; are more concerned about erosion on their land; have made a recent major investment in the farm; use other producers for tillage information; have the management skill for conservation tillage; and believe conservation tillage will fit with their production...

DETERMINING SOCIALLY OPTIMAL NITROGEN APPLICATION RATES USING A DELAYED RESPONSE MODEL:  THE CASE OF IRRIGATED CORN IN WESTERN KANSAS
Provedor de dados: 31
Autores: Nkonya,   Ephraim M.; Featherstone,   Allen M.
Nitrate contamination of groundwater is an important problem. The transport of leached nitrate from the root zone to groundwater takes approximately 30 to 60 years. Many previous studies ignore this time lag by assuming instantaneous contamination. This analysis applies a delayed response model to account for the time lag between nitrogen fertilizer applications to the time the leached nitrate reaches groundwater. Results show that accounting for the leached nitrate externality reduces the nitrogen application rate by 13% and the returns above variable costs by 8% for farmers who apply both nitrogen and phosphorus. For farmers who do not use phosphorus, nitrogen use is reduced by 14% and the returns above variable costs by 22%. The application of...

Fruit production and consumption have increased considerably in the past few decades in Taiwan. Market prices of fruits fluctuate in response to seasonality, changes in production costs, imports and exports, and demand. Some factors are more influential to fruit price changes. This research utilizes the Vector Autoregressive Model to analyze effects of exogenous shocks to market prices of fruits. Dynamic models were developed for bananas, grapes, guavas, papayas, pineapples, and watermelons. For the market of bananas, prices of pesticides have delayed positive effects; an increase of watermelon prices raises the prices of bananas; prices of banana exports explain some variations of domestic banana prices. For the market of grapes, income, interest rates,...

A Nonlinear Offset Program to Reduce Nitrous Oxide Emissions Induced by Excessive Nitrogen Application
Provedor de dados: 31
Autores: Rosas,   Francisco; Babcock,   Bruce A.; Hayes,   Dermot J.
On average, U.S. farmers choose to apply nitrogen fertilizer at a rate that exceeds the ex post agronomically optimal rate. The technology underlying the yield response to nitrogen rewards producers who over apply in years when rainfall is excessive. The overapplication of nutrients has negative environmental consequences because the nitrogen that is not taken up by the plant will typically volatilize causing N2O emissions, or leach causing water pollution. We present a nonlinear offset program that induces farmers to reduce their nitrogen applications to the level that will be consumed by the plant in a typical year and, as a result, reduce N2O emissions from agriculture. The offset program is nonlinear because of the nonlinear relationship between N2O...

In this study, we estimate an output distance function in the context of a multi-output and multi-input production technology by stochastic frontier techniques. Unbalanced panel data for smallholder farms that grown cassava and other crops in Southwestern Nigeria covering 2006/07 to 2008/09 farming seasons is used for the analysis. The results show that the marginal rate of transformation (MRT) between “other crops” grown by the farmers and cassava produced relative to the output mix is negative and significantly different from zero. We observed also that increasing returns-to-scale as well as technical progress characterized cassava production in the region. Furthermore, fertilizer and pesticides are found to have significant substitution effects on...

The effect of soil quality on fertilizer use rates among smallholder farmers in western Kenya
Provedor de dados: 31
Autores: Marenya,   Paswel Phiri; Barrett,   Christopher B.
Studies of fertilizer use in sub-Saharan Africa have been dominated by analyses of economic and market factors having to do with infrastructure, institutions, and incentives that prevent or foster increased fertilizer demand, largely ignoring how soil fertility status conditions farmer demand for fertilizer. We apply a switching regression model to data from 260 farm households in western Kenya in order to allow for the possibility of discontinuities in fertilizer demand based on a soil carbon content (SCC) threshold. We find that the usual factors reflecting liquidity and quasi-fixed inputs are important on high-SCC plots but not on those with poorer soils. External inputs become less effective on soils with low SCC, hence the discernible shift in...

Measuring the poverty impact of ACIAR projects: a broad framework
Provedor de dados: 31
Autores: Pearce,   David.
This report sets out some broad ideas about how poverty evaluation could be conducted for ACIAR research projects. As with good benefit–cost analysis, there are good practices that need to be observed when undertaking poverty analysis. While poverty is a broad concept, and can be addressed through many means, these need to be grounded in some common understanding of the economics of poverty. This report is concerned mostly with quantitative evaluation, in the same sense that current ACIAR project evaluations are quantitative. That is, it is concerned with saying something about the order of magnitude of the effects of the project. Of course, qualitative analysis is important, and in most cases is a prelude to quantification — there is little point...

The purpose of this study was to measure the economic contribution of the soybean industry to the North Dakota economy. Expenditures and returns from soybean production, grain handling, and transportation were estimated to calculate the direct economic impacts from soybean activities. Secondary economic impacts were estimated using the North Dakota Input- Output Model. Soybean production in North Dakota has trended upward over the past three decades. Increases in acreage were relatively modest in the 1980s, but by the mid 1990s acreage was beginning to rapidly expand. In 1990, North Dakota had about 500,000 acres of soybeans. By 2000, acreage had increased to 1.9 million acres. By 2009, soybean acreage in the state was approaching 4 million acres. Direct...

Pesticides Uses in Crop Production: What Can We Learn from French Farmers Practices?
Provedor de dados: 31
Autores: Fadhuile,   Adelaide; Lemarie,   Stephane; Pirotte,   Alain.
This article focuses on the demand system of French farmers concerning pesticides uses. We estimate the demand elasticities of herbicides, insecticides and fungicides with respect to pesticide expenditure, and considering crop differentiation. Then we compare two indexes that are used in agronomic literature to measure the intensity of pesticides uses. We retain a Linear Approximated Almost Ideal Demand System (LA/AIDS) specification. A Full-Information Maximum Likelihood estimation procedure is used for dealing with the problem of censored dependent variable. We consider two cross-sections observed in 2001 and 2006 covering pesticides uses of three crops. We confirm the previous results of the literature that farmers response to price variation is very...

Autores: Mahoo,   Henry F.; Mkoga,   Zakaria Juma; Kasele,   Sydney Stephen; Igbadur,   Henry E.; Hatibu,   Nuhu; Rao,   Karuturi P.C.; Lankford,   Bruce A.
Stakeholders in agriculture and water related issues have different perceptions about the productivity of water. This is evident by the different definitions of productivity of water, though most of the definitions hinge around the benefits accrued from water use. The viewpoint of smallholder farmers’ regarding the productivity of water is important in order to promote the concept of productivity of water in a country like Tanzania. This is because 95 percent of the farmers are smallholders. This paper presents the farmers’ understanding of the productivity of water in the Mkoji sub-catchment (MSC) in the Ruaha River Basin in Tanzania. It also presents their practices aimed at increasing the productivity of water in the area. It reveals that the concept of...

Demand for Irrigation Water for Pistachio Production from Depleting Groundwater Resources: Spatial Econometric Approach
Provedor de dados: 31
Autores: Jaghdani,   Tinoush Jamali; Brümmer,   Bernhard.
Depletion of groundwater resources is an international problem, and groundwater is probably the world’s most extracted raw material. The agriculture sector is one of the biggest users of groundwater resources for irrigation activities, and it plays an important role in the depletion of these resources. The estimation of demand function for groundwater resources is the first step toward any policy recommendation in this field of research. However, only scarce attention has been given to empirical studies of the demand structure of groundwater resources by the help of econometrics and considering the quality of the resources in the context of a single aquifer. Therefore, an empirical estimation of the demand function for individual users which considers...

Conditions Necessary for Private Investment in the Ethanol Industry
Provedor de dados: 31
Autores: Kenkel,   Philip L.; Holcomb,   Rodney B.
While agricultural economics literature has become rife with the economics of ethanol production and cellulosic ethanol feedstock production, little has been written about capital investment necessary for the magnitude of industry development mandated by the Energy Security and Independence Act of 2007. Financing the development of the ethanol industry to meet the 36 billion gallon production capacity set for 2022 (with 16 billion gallons from cellulosic ethanol) will require capital investments exceeding $100 billion for production facilities, plus extensive investment in feedstock establishment and transportation/handling infrastructure. Federal support associated with political mandates does not address all of the financial issues related with the...

Collective Action in Ant Control
Provedor de dados: 31
Autores: Ravnborg,   Helle Munk; de la Cruz,   Ana Milena; del Pilar Guerrero,   Maria; Westermann,   Olaf.
Leaf-cutting ants (Atta. cephalotes) represents a serious problem to farmers in many parts of Latin America and accounts of ants eating up a whole cassava plot or destroying one or more fruit trees overnight are not uncommon. Ants do not respect farm boundaries. Therefore, farmers who control anthills on their own fields might still face damage on their crops caused by ants coming from neighboring fields where no control measures are taken. In that sense, crop damage caused by leaf-cutting ants constitutes a transboundary natural resource management problem which, in addition to technical interventions, requires organizational interventions to ensure a coordinated effort among farmers to be solved. This paper reports on a research effort initiated by CIAT...

THE EFFECT OF QUALITY ASSURANCE POLICIES FOR PROCESSING TOMATOES ON THE DEMAND FOR PESTICIDES
Provedor de dados: 31
Autores: Starbird,   S. Andrew.
In California, acceptance sampling is used to monitor the quality of processing tomatoes delivered by growers to processors.  A proposal to change the current quality assurance policy was recently put forth to reduce the growers’' incentive to use pesticides.  In this article we examine the effect of alternative quality assurance policies on profit-maximizing grower’s' demand for pesticides.  The results indicate that the demand for pesticides is sensitive to changes in the quality assurance policy and that the proposed policy would reduce the optimal level of pesticide use on processing tomatoes.  Disregarding the impacts of quality assurance policy may be the reason that the demand for pesticides has been underestimated so often in the past.

Bt Corn Farmer Compliance with Insect Resistance Management Requirements: Results from the 2002 Minnesota and Wisconsin Farm Polls
Provedor de dados: 31
Autores: Buttel,   Frederick H.; Merrill,   Jeanne; Chen,   Lucy; Goldberger,   Jessica; Hurley,   Terrance M.
The U.S. Environmental Protection Agency (EPA) reregistered Bt corn in 2001 with mandatory Insect Resistance Management (IRM) requirements in order to promote sustainable use by farmers.  Since then studies report IRM compliance rates ranging from 80 to 90 percent.  Using survey data from Minnesota and Wisconsin, we show that previous compliance rate estimates are likely too high because they do not use a comprehensive measure for compliance.  With a more comprehensive measure, we find compliance rates ranging between 60 to 75 percent.

SUPPLY RESPONSE IN THE WHEAT-BELT OF SOUTH-EASTERN AUSTRALIA: THE IMPACT OF DELIVERY QUOTAS ON WHEAT PLANTINGS
Provedor de dados: 31
Autores: Fisher,   Brian S.
Supply response equations were estimated for a number of regions in south-eastern Australia using the area sown to wheat as the response variable. These equations were used to determine the effect of delivery quotas on the area of wheat sown in those regions. Results from this study indicate that delivery quotas were only effective in reducing wheat plantings in the south-eastern Australian wheat-belt in the 1970-71 season. Plantings in other seasons in which delivery quotas were applied could be explained using variables such as wheat prices and a time trend.

Autores: Silva,   Leonardo Xavier da.
A cadeia agroindustrial do tabaco no sul do Brasil está estruturada a partir de dois grupos distintos. De um lado, centenas de milhares de pequenos agricultores e, de outro, uma indústria constituída por um oligopólio de capital multinacional. A produção é a de fumos claros, cujo principal mercado é o externo, que o compra para transformá-lo em cigarros. O Brasil é o líder mundial dos negócios em tabaco para cigarros e nos últimos três anos têm-se colocado diante de um fato novo: a Convenção-Quadro para o controle do Tabaco, documento confeccionado e assinado por mais de cem países e cujo objetivo é reduzir a produção da folha no mundo. As reações dos agentes da cadeia têm sido distintas. Pelo lado dos agricultores, instituições como a Associação dos...

Farmers' Use of Improved Seed Selection Practices in Mexican Maize: Evidence and Issues from the Sierra de Santa Marta
Provedor de dados: 31
Autores: Rice,   Elizabeth; Smale,   Melinda; Blanco,   Jose-Luis.
The principal advantage of in situ conservation is that it allows adaptive evolutionary processes to continue in the species that are being conserved. For a cultivated crop species, in situ conservation involves farmers' management of their own genetic resources even as the farmers themselves adapt to a changing environment. Improved seed selection practices and other on-farm breeding strategies have been proposed as a means of providing economic incentives for farmers to continue growing traditional varieties or landraces identified as important for conservation. This paper describes a pilot study among a group of indigenous farmers in the Sierra de Santa Marta, Veracruz, Mexico, who have collaborated in such efforts. The findings raise key issues about...

Autores: Wegener,   Malcolm K.; Tullberg,   J.N.; Pearson,   L.E.
Dryland grain farmers in some 30 counties in Shanxi Province, Peoples Republic of China, are now practising some form of conservation tillage farming following a successful research and technology transfer project. While this represents only 5 percent of graingrowing land in the province, it marks the start of a trend that will lead to major changes in farming in China if the apparently attractive economics of conservation farming are confirmed. As well as the trend to conservation tillage farming in Chinese agriculture, there are other fundamental changes occurring. With the introduction of mechanisation, there are incentives to increase farm size and the structural changes that could flow from this could see farm workers displaced. The cost savings from...

Autores: Bhalla,   G.S.; Hazell,   Peter B.R.; Kerr,   John M.
IFPRI’s “2020 Vision Initiative for Food Agriculture, and the Environment” is intended to develop a shared vision on how to meet future world food needs while reducing poverty and protecting the environment. It brings together divergent schools of thought on these issues, working on the principle that divergent views can generate a constructive dialogue that will ultimately lead to a consensus for action. The current paper on projected supply and demand for cereals in India, and the possibility of an emerging cereal gap of serious proportions by the year 2020, is a useful illustration of the kind of constructive dialogue IFPRI hopes to encourage. It responds to several quite recent developments, notably the rapid expansion of India’s industrial and service...

ADOPTION OF DOUBLE-CROPPING SOYBEANS AND WHEAT
Provedor de dados: 31
Autores: Shapiro,   Barry Ira; Brorsen,   B. Wade; Doster,   D. Howard.
Double-cropping of soybeans and wheat is often promoted by extension personnel.  This paper seeks to explain how the decision to adopt double-cropping is made, using a Tobit regression model.  Tobit makes use of more of the information in the data set than do logit or probit and explains not only the decision to double-crop but also the rate of adoption.  The paper considers factors such as profit and risk perceptions and risk which have not been included in the past models used to explain adoption of technology.  The results show that risk perception is important.  Contrary to the findings of some other adoption studies, this decision is not influenced by human capital factors.  The farmers who double-crop are more highly leveraged and appear to do so...

Determinants of farmers’ compliance with coffee eco-certification standards in Mt. Kenya region
Provedor de dados: 31
Autores: Kirumba,   E.G.; Pinard,   F.
This paper sought to investigate determinants of farmers’ compliance with coffee eco-certification standards in Mt. Kenya region. Socio-economic, institutional and farm factors were analyzed and the binary logistic regression model was used to predict factors enhancing compliance. The findings show that perception of benefits, coffee as the main source of income, annual coffee production, and the number of times a farmer sprayed annually; were the main drivers of compliance. The findings point towards a growing concern that certification projects focus on ‘progressive’ farmers rather than seek to uplift and integrate ‘weak’ farmers. This calls for concerted efforts among all key stakeholders to enhance inclusivity and participation.

The fertilizer sector in Zimbabwe has evolved over the years in response to different policy changes based on the government’s priorities on agricultural development. The industry grew from the 1930s that targeted primarily large scale commercial farmers, through the liberalization period of the mid 1990s, and recent changes that have introduced controls on the marketing system. Since 2000, following the fast track land reform program, Zimbabwe has faced food insecurity challenges that have been exacerbated by the political and economic crises. This prompted the government to adopt policies that have reduced private sector interests in fertilizer supply. In this situation where explicit fertilizer markets have been absent, relief programs have been leading...

The Carbon Challenge for Mixed Enterprise Farms
Provedor de dados: 31
Autores: Kingwell,   Ross S.
As part of its climate change policy the Australian government has introduced a Mandatory Renewable Energy Target (MRET) scheme and is also attempting to introduce a Carbon Pollution Reduction Scheme (CPRS). Using as a case study a main agricultural region of Australia, this paper examines how farming systems in this region may be affected by the medium term policy settings of these two schemes. A bio-economic model of the region’s farming systems is developed and used to assess the schemes’ impacts on the nature and profitability of the farming systems. Results show a range of profit and enterprise impacts across the range of farming systems. Farms as providers of biomass for electricity generation and small users of electricity are liable to benefit from...

Analysis of the Impact of CIMMYT Research on the Australian Wheat Industry
Provedor de dados: 31
Autores: Brennan,   John P.; Quade,   Kathryn J.
Wheat genetic materials developed from research at the International Maize and Wheat Improvement Center (CIMMYT) in Mexico for developing countries have provided spillover benefits to Australia. Varieties developed from those genetic materials have resulted in yield increases in Australia. CIMMYT’s success in developing countries has also reduced the world price for wheat. While the lower prices affect returns in Australia, the increased yields in Australia from the CIMMYT spillovers have provided benefits to Australia averaging A$30 million per year since 1973. If these benefits are to continue in the future, Australia must continue its close relationship with CIMMYT.

Agriculture in India occupies an important place as it contributes nearly 25 per cent of GDP and two-thirds of the population depend upon it. Agricultural growth in the past has been sufficient to move from severe food crisis to aggregate food surplus today. The rainfed regions are diverse in terms of resource base, varying from resource rich regions harnessing substantial production to resource poor regions with restricted potential. These resource poor regions are mostly dominated by secondary crops. Barring maize and potato, secondary crops are loosing ground against the finer cereals, cash and commercial crops. Therefore, there is an urgent need to provide a leverage to these crops by providing support in terms of technological advancement and policy...

The paradox of household resource endowment and land productivity in Uganda
Provedor de dados: 31
Autores: Ainembabazi,   John Herbert; Angelsen,   Arild.
The paper investigates the conflicting findings in empirical studies linking land productivity to plot size, livestock ownership, investment in farm assets, and land improvement practices. The conflicting impacts found are partly as a result of different model specifications, the type of data used – panel or cross sectional data – and possibly due to imperfections in rural markets. We control for these problems using household and plot level panel data from rural farmers in Uganda. We find that ownership of cattle has a negative and significant impact on land productivity. Investment in farm related assets, land improvements and other small livestock, however, significantly increases productivity. The conflicting impacts are a result of measurement error....

Are EU spatial ex ante coexistence regulations proportional?
Provedor de dados: 31
Autores: Demont,   Matty; Daems,   W.; Dillen,   Koen; Mathijs,   Erik; Sausse,   C.; Tollens,   Eric.
The EU is currently struggling to implement coherent coexistence regulations on genetically modified (GM) and non-GM crops in all member states. While it stresses that any approach needs to be “proportionate to the aim of achieving coexistence”, very few studies have actually attempted to assess whether the proposed spatial ex ante coexistence regulations (SEACERs) satisfy this proportionality condition. In this article, we define proportionality as a functional relationship which is weakly increasing in the incentives for coexistence. We propose a spatial framework based on an existing landscape and introduce the new concept of shadow factor as a measure for the opportunity costs induced by SEACERs. This enables comparing the proportionality of (i) rigid...

Using a principal-agent model, we find the optimal subsidy contract that induces grower compliance with Bt corn refuge requirements for managing insect resistance when asymmetric information exists concerning grower behavior.  The optimal contract balances the cost of monitoring and the benefit of reducing the likelihood of insect resistance.

Consumers’ Willingness to Pay for Food Safety in Nairobi: The Case of Fresh Vegetables
Provedor de dados: 31
Autores: Lagerkvist,   Carl Johan; Hess,   Sebastian; Ngigi,   Marther W.; Okello,   Julius Juma.
Large urban areas in developing countries represent currently the most dynamically growing markets for food products. This study investigates the willingness to pay of consumers in Nairobi for safer leafy vegetables. We survey individuals’ perceived food safety across four major market categories, while also considering the explanatory role of trust and behavioral, psychological, and socio-demographic covariates. Results show that willingness to pay is market-specific and multi-faceted, with trust and perceived risks as important drivers, while income plays only a subordinate role. We conclude that policy makers should aim to reduce asymmetric information within the value chain without raising food prices such that safer vegetables would become...

Changing Pattern in U.S. Apparel Trade Post-2008: Implications for U.S. Cotton
Provedor de dados: 31
Autores: Mutuc,   Maria Erlinda M.; Mohanty,   Samarendu; Malaga,   Jaime E.; Rejesus,   Roderick M.
In 1995, the Agreement on Textiles and Clothing (ATC) provided for the calculated liberalization of the textiles and apparel sectors over a 10-year period ending in 2005, except for some safeguard measures ending on December 31,    2008.  These safeguard measures allowed for import restrictions by the U.S. on certain categories of cotton apparel from China.  Using a 57-equation, annual econometric, price equilibrium simulation model of the U.S. cotton and cotton apparel markets, results point to lower cotton apparel prices in the U.S. by as much as $ 0.25 per kilogram while cotton prices decline by less than $ 0.01 per kilogram once these safeguards expire.  In the baseline scenario, quotas are removed in 2009-2015 except for the safeguards. In the...

Simulation of production budgets were used to compare net discounted returns and the distribution of returns under alternative risk-mitigation scenarios.  Results indicate that the combination of freeze protection and crop insurance increases expected net discounted 20-year returns while decreasing the downside risk.  Break-even prices ranged from $.257 to $.289 per pound.  Crop insurance returns were constant across price.

DYNAMIC REGIONAL ANALYSIS OF THE CALIFORNIA ALFALFA MARKET WITH GOVERNMENT POLICY IMPACTS
Provedor de dados: 31
Autores: Konyar,   Kazim; Knapp,   Keith C.
Alfalfa's heavy reliance on irrigation water and its role as an alternate to program crops makes it susceptible to changes in government farm policies. This article presents a dynamic spatial equilibrium model of the California alfalfa market. The model is used to forecast alfalfa acreage, prices paid and received, and transportation flows for the short run and the long run under the base year conditions. The base year results then are compared to a situation of changing demand due to reductions in federal water subsidies and the implementation of a cotton acreage-reduction program.

Autores: Tranel,   Jeffrey E.; Hewlett,   John P.; Weigel,   Randolph R.; Rahman,   Tauhidur; Teegerstrom,   Trent; Ehmke,   Cole.
This report presents the preliminary results of a statistically valid 2006 survey of small agricultural producers (sales of less than $50,000) in three Western states (Wyoming, Colorado and Arizona). The West has undergone significant change, and the composition of farm managers has changed with it. This report provides information from farm operators in the rural West  on their perceived threats as well as characteristics of themselves and their operations. Topics of interest were demographics, reasons for involvement in agriculture, income, resource management (crops and livestock), and preferences for information delivery. The project was supported by the Western Center for Risk Management Education.

During participatory rural appraisals, farmers at the Lake Victoria basin of Kenya and Uganda identified Striga, stemborer and declining soil fertility as three major constraints to maize production To reduce food insecurity, several innovative integrated technologies to address these constraints have been developed, including push-pull (maize intercropped with Desmodium and surrounded by napier grass), maize-soybean and maize-crotalaria rotations, and Imazapyrresistant (IR) maize seed coated with the herbicide. To let farmers evaluate the new technologies, 12 demonstration trials, comparing the different technologies, were established in four villages in Siaya and Vihiga districts (Western Kenya) and two villages in Busia (Uganda).

Autores: Maynard,   Leigh J.; Harper,   Jayson K.; Hoffman,   Lynn D.
Stochastic dominance analysis of five crop rotations using twenty-one years of experimental yield data returned results consistent with Pennsylvania cropping practices.  The analysis incorporated yield risk, output price risk, and rotational yield effects.  A rotation of two years corn and three years alfalfa hay dominated for approximately risk neutral and risk averse preferences, as did participation in government programs under the 1990 Farm Bill.  Crop rotation selection appeared to impact net revenues more than the decision to participate in government programs.

The likely regional impacts of an agricultural emissions policy in New Zealand: Preliminary analysis
Provedor de dados: 31
Autores: Sin,   Isabelle; Brunton,   Emma; Hendy,   Joanna; Kerr,   Suzi.
Hendy and Kerr (2005b) find that an emissions charge on agricultural methane and nitrous oxide of $25 per tonne of carbon dioxide (CO2) equivalent would be likely to reduce New Zealand‘s net land-use related emissions for commitment period one in the order of 3%, with full accounting. The costs per farmer and as a percentage of profit would be very high. This paper considers the regional impacts of such a policy in New Zealand by allocating the emission charge across space according to the location of animals. We then combine our emissions charge information with data on the socio-economic characteristics of the affected areas. Obviously rural areas are heavily affected. In many respects, for example median income, ethnic mix, and percentage of working...

Territory and natural conditions in Macedonia are well known in the World market of high quality production of oriental type of tobacco. Production of oriental tobacco at such a small territory is insignificant towards other producers (Bulgaria, Turkey), buy it is very important for Macedonian economy. The high value of exported tobacco and other tobacco products is regularly above 100 million USD (113 million USD for 2006 and 106 million USD for 2007). As a family production with low grade of mechanized labor processes, it provides survival of more than 100 000 residents of Macedonia. These reasons are enough to evaluate the importance of tobacco for a country with a gross national income per capita of around $4,120 in 2008, (GNI, Atlas method) and high...

MEXICAN-U.S. FRESH TOMATO TRADE: AN ANALYSIS OF VOLUME, PRICES AND TRANSACTION COSTS
Provedor de dados: 31
Autores: Padilla-Bernal,   Luz E.; Thilmany,   Dawn D.
Tomato trade between the U.S. and Mexico has grown significantly during the past decade. Although the tariff reductions accorded under NAFTA may explain part of his increase, there are other supply and demand factors that affect trade flows. This study develops a U.S.-Mexico tomato trade model, with special focus on the interdependence between trading costs and the volume of Mexican imports. As expected, the exchange rate is a significant determinant of trading costs, but the level of tariffs was insignificant in both the trading and tomato supply equations. The shipping point price level and volume of imports also appear to affect these costs. For the import supply and demand models, there appears to be a significant share of imports that rely on previous...

Optimal export taxes – the case of cocoa in Cote d'Ivoire
Provedor de dados: 31
Autores: Burger,   Kees.
Export taxes can provide additional welfare to large exporters, an argument for interventions in many primary commodity exporting countries. We investigate the benefits of export taxation for Côte d'Ivoire, the dominant exporter of cocoa. Where many applications treat the formula for optimal export taxes incorrectly as a prescription, we take the endogeneity of the exporter’s share into account. We also distinguish between short-term and long-term effects, relevant for a tree crop like cocoa and we allow for a normal commercial margin between export and farm gate prices. Results are calculated via simulations in a model, in which the age-compositions of the tree stocks of major producing countries are distinguished. Simulations over a period of 15 years...

Giving credit to the microlenders. Formal microlending, credit constraints and adverse selection: a case study of shrimp farmers in Bangladesh
Provedor de dados: 31
Autores: Andersson,   Camilla I.M.; Holmgren,   Erik; MacGregor,   James; Stage,   Jesper.
Smallholder farmers have long been denied access to formal credit, largely because of the high administrative fees associated with loans. A possible solution to this problem, which has become increasingly popular, is the use of microcredit financing, where innovative means of securing the loans, such as peer monitoring, are used. This paper examines the effectiveness of formal microcredit schemes as compared to the traditional informal credit sources in a rural shrimp farming district of Bangladesh. We compare the two types of credit by studying the technical and allocative efficiencies of the two groups of borrowers. The findings suggest that farmers using both types of microcredit have difficulty accessing credit, often over-utilising labour in order to...

Autores: de Herrera,   Adys Pereira; Sain,   Gustavo.
An aggressive research and validation program launched in 1984 in Azuero, Panama, yielded a recommendation advocating zero tillage for maize production. Ten years later, maize farmers in Azuero used three land preparation methods: conventional tillage, zero tillage, and minimum tillage (an adaptation of the zero tillage technology). This study aimed to quantify the adoption of zero and minimum tillage for maize in Azuero; identify factors influencing adoption of the different land preparation practices; and analyze the implications of the findings for future maize research and extension. Between 1985 and 1994, farmers in Region I of Azuero changed from conventional tillage to zero (33%) and minimum tillage (43%). In Regions II and III, most farmers still...

This paper examines how the fertilizer sector in general, and farmers’ demand for  fertilizer in particular, has evolved since the introduction of fertilizer sector reforms in  Ethiopia. There is much debate in the agricultural development literature about whether fertilizer  use in Africa is constrained primarily by poor input distribution systems, by farmers’ lack of  knowledge concerning the benefits and correct use of fertilizer, or by lack of effective demand  because the product is simply not profitable enough. This paper looks at each of these issues in  an effort to understand the relative importance of the different constraints and how well current  policies are addressing the problems. It attempts to identify additional policy measures needed  to...

This paper provides an overview of concepts of sustainable agriculture and possible methods of attaining sustainability of agricultural yields and production. Reasons are given as to why modern industrialised agriculture might be less sustainable in terms of yields than traditional agriculture. The question of whether organic agriculture is likely to be more sustainable than non-organic agriculture is considered as well as organic agriculture’s likely impact on wild biodiversity. The impact of the development of agriculture on wild biodiversity is assessed because some environmentalists see the conservation of wild biodiversity as an important ingredient of sustainable development. However, there is a policy conflict between conservationist groups. Some...

A Dynamic Nutrient Carryover Model for Pastoral Soils and its Application to Optimising Fertiliser Allocation to Several Blocks with a Cost Constraint
Provedor de dados: 31
Autores: Woodward,   Simon J.R.
A dynamical model of soil phosphorus carryover in grazed pasture provides the basis for bioeconomic optimization of fertiliser rates. A linear constraint is introduced to optimise the allocation of limited funds to fertiliser on several farm blocks, each of which represents a different land and/or stock class. The optimal constrained maintenance application of fertiliser to each block is calculated, and an heuristic approach to this equilibrium is suggested. In some cases this involves withholding of fertiliser from unresponsive blocks. The dynamical model and economic optimisation method have been implemented in a commercial fertiliser planning decision support tool Outlook.

Two Stage Least Squares and principal component analysis were used to estimate the export demand and supply of South African (SA) fresh oranges in the United Kingdom (UK) during 1976-1993. Export demand was negatively related to the SA fresh orange price relative to the price of fresh oranges from Israel, and positively related to lagged orange exports (consumer brand loyalty proxy). Export supply was positively related to lagged net export realisation price relative to domestic orange price, the SA fresh orange price in the UK relative to the SA fresh orange price in France, lagged exports (export orientation), and supply shocks. The relative price elasticity of export demand was inelastic in both the short- and long-run, indicating that Capespan...

Autores: Deodhar,   Satish Y.; Sheldon,   Ian M.
In this article, the degree of imperfect competition in the world market for soymeal exports is estimated using a structural econometric model. The procedure consists of estimating a demand function and the industry first-order profit-maximization condition, from which an estimate of the degree of market power can be retrieved. Using a nonlinear three-stage least squares procedure, the estimate of market power shows that the world market for soymeal exports is perfectly competitive. The empirical results also indicate that this market was competitive even prior to entry by Argentinean firms in the mid-1970s.

Global food commodity price inflation beginning in 2006 and continuing through mid-2008 became a priority concern for global consumers, producers and policy-makers alike.  In response, many governments across the world implemented policies targeting high food commodity prices in their domestic markets.  These policy responses were concentrated in lower income countries and primarily targeted rice and wheat. The 2007-08 policy responses across countries included liberalized import tariffs, export restrictions and increased domestic support for both consumers and producers.

A bioeconomic model for determining the optimal response to a new weed incursion in Australian cropping systems
Provedor de dados: 31
Autores: Jayasuriya,   Rohan T.; Jones,   Randall E.
Invasions by non-indigenous plant species pose serious economic threats to Australian agricultural industries. When an invasion is discovered a decision has to be made as to whether to attempt to eradicate it, contain it or do nothing. These decisions should be based on long term benefits and costs. This paper describes a bioeconomic simulation framework with a mathematical model representing weed spread linked to a dynamic programming model to provide a means of determining the economically optimal weed management strategies over time. The modelling framework is used to evaluate case study invasive weed control problems in the Australian grains industry.

At a macro-level, however, farm output and productivity have stagnated and poverty rates have remained stubbornly high, even increasing in some areas. It is widely acknowledged that policy and infrastructural constraints play a large role in reducing incentives for farmers to invest in agriculture. Yet the fact that farmers have made some investments and that some progress has occurred suggests that characteristics of the technologies themselves, or the way in which they are promoted, also facilitate or inhibit wider adoption and impact. This research report, part of a set of studies on the...

Variety Choice by Australian Wheat Growers and Implications for Genetic Diversity
Provedor de dados: 31
Autores: Brennan,   John P.; Godden,   David P.; Smale,   Melinda; Meng,   Erika C.H.
Genetic diversity in agricultural systems relies on both the supply of diversity through varieties produced by breeding programs, and the demand for that diversity, through farmers' usage of varieties. Variety choice by farmers is demonstrated through the mix of varieties that is grown in a given region. In this paper, the conceptual issues relating to the supply of and demand for genetic diversity are explored. An empirical analysis of the varietal demand, based on the varieties grown in the Temora Shire in southern NSW over the post-War period, is undertaken. Changes over time in the choice of varieties by farmers are analysed, and some implications for genetic diversity are discussed.

This report summarizes the 2003 financial and production records of 92 Michigan cash grain farms. To be included, the farms must have produced at least 50 percent of gross cash farm income from one or a combination of these items; corn, soybeans, wheat, all varieties of navy beans, oats, sugar beets and other small grains. The records came from Michigan State University's TelFarm/MicroTel project, the Farm Credit Service system, or by AgriSolutions in Michigan. The values were pooled into averages for reporting purposes.   Farm records were included if a farm financial analysis was completed on 2003 data including beginning and ending balance sheets, plus income and expenses. The data were checked to verify that cash discrepancy was less than 10% of gross...

The Effect of Climate Change, CO2 Fertilization, and Crop Production Technology on Crop Yields and Its Economic Implications on Market Outcomes and Welfare Distribution
Provedor de dados: 31
Autores: Attavanich,   Witsanu; McCarl,   Bruce A.
Many studies have done econometric estimates of how climate alters crop yields and or land rents in an effort to gain information on potential effects of climate change.  However, an important related factor, the atmospheric carbon dioxide (CO2) concentration, and in fact a driver of climate change is ignored.  This means the prior econometric estimates are biased as they infer what will happen under climate change from observations in the recent past, but without consideration of CO2 effects.  Furthermore although CO2 has been varying, it has proceeded at a very linear pace and cannot be disentangled from technological progress using historical crop yield data.  This paper is designed to overcome this issue and estimate the consequences that CO2 has and...

Autores: Makus,   Larry D.; Guenthner,   Joseph F.; Lin,   Biing-Hwan.
A probit model identifies characteristics influencing Idaho potato producer support or opposition to a state mandatory certified seed law. Economic self interest appears to be the most important influencer. Current users of certified seed and growers of certified seed are strong supporters. However, producer attitudes about the impact of seed-borne diseases and effectiveness of certified seed as a control mechanism also are important. Respondent characteristics (gross farm income, potato acreage, and geographic region of the state) seem to be less important influencers.

ASSESSING THE IMPACT OF THE EXCHANGE RATE AND ITS VOLATILITY ON CANADIAN PORK AND LIVE SWINE EXPORTS TO THE UNITED STATES AND JAPAN
Provedor de dados: 31
Autores: Fabiosa,   Jacinto F.
A model of a representative Canadian pork exporter is developed to examine the impacts of the exchange rate and its volatility on pork and live swine exports. The pork export supply equation is expressed as a function of the expected level of real exchange rate and a time-varying variance of real exchange rate. An AR(p) model is used to represent the expected real exchange rate, and a GARCH(p, q) model is used to generate the time-varying variance. The same model is used to examine the sensitivity of pork exports to Japan from Canada, the United States, and Denmark. The parameters of all pork and live swine export equations have theoretically consistent signs and many are significant. That is, the domestic price in the exporting country has a negative...

FACTORS AFFECTING WHEAT PROTEIN PREMIUMS
Provedor de dados: 31
Autores: Parcell,   Joseph L.; Stiegert,   Kyle W.
This study used Rosen's methodology of deriving a marginal implicit price series from traditional hedonic modeling and then using this series to estimate a demand model.  This procedure was applied to Kansas Hard Red Winter wheat protein.  Results were mixed.  Own-district protein level was not economically significant; however, an increase in other Kansas district's protein level and the North Dakota Hard Red Spring protein level may have a slight economic impact on own-district protein premium.  The results of this study indicate that new varieties of wheat developed that increase protein content without loss of yield and that are regional specific can impact the price or wheat in other areas.

Agricultural Arbitrage, Adjustment Costs, and the Intensive Margin
Provedor de dados: 31
Autores: Tack,   Jesse B.; LaFrance,   Jeffrey T.
Farmland and capital are an important and rapidly expanding component of the agricultural economy, and empirical evidence suggests that these assets are quasi-fixed in that adjustment costs are incurred when holdings are altered. Increased interest in the rate of return for investing in farmland suggests that an important consideration is the effect of adjustment costs on this return. A novel theoretical model is developed that ties together contributions from the farmland pricing and adjustment cost literatures, and the first order conditions for a utility maximizing decision maker are rearranged into intertemporal arbitrage equations that are similar in spirit to traditional finance models. The common assumptions that land and capital are quasi-fixed...

A multinomial logit is utilized to model the choice of whether to purchase yield or revenue insurance using subjectively elicited survey data. Our results indicate that the demand for crop insurance is inelastic (-0.40), consistent with most earlier yield elasticity estimates, but the elasticity for choices between yield and revenue insurance is found to be relatively more elastic (-0.88).

Autores: Key,   Nigel D.; Roberts,   Robert J.
This study uses matching to evaluate the effect of decoupled payments on the acreage response of Iowa farmers who were in business in 1997 and 2002. Using farm-level panel data from the U.S. Agricultural Census, we examine whether farmers receiving high levels of 1997 agricultural payments per acre had a greater increase in program crop acreage between 1997 and 2002 than farmers receiving low levels of payments. The panel data set allows for conditioning current acreage on past individual acreage and operator characteristics. The large and exhaustive sample allows for comparisons across similar farms. The matching methodology avoids distributional and functional form assumptions about the relationship between the treatment and outcome. Results are...

AIR POLLUTION AND FARM-LEVEL CROP YIELDS: AN EMPIRICAL ANALYSIS OF CORN AND SOYBEANS
Provedor de dados: 31
Autores: Westenbarger,   David A.; Frisvold,   George B.
While many studies have estimated the impacts of air pollution on crop yields on experimental plots, few have estimated these impacts under actual farm production conditions.  This study econometrically estimates the impact of air pollution on corn and soybean yields, controlling for weather, soil quality and management practices, using farm-level data for the eastern United States.  Ozone pollution was found to reduce yields for both crops.  The mean elasticity of yield with respect to ozone exposure was -0.19 for corn and -0.54 for soybeans.  The benefits of ozone standards to protect crops, measured in terms of crop revenues, range from $17 to $82 million depending on the stringency of the standard.  Over 85 percent of the revenue gains are captured by...

ALERT:  FARMERS NEED TO SIGN UP FOR ACRE!
Provedor de dados: 31
Autores: Hilker,   James H.; Betz,   Roger; Black,   J. Roy.
Corn, soybean and wheat producers are facing serious financial challenges. And it is even worse for livestock producers, most of who are also crop producers and are therefore eligible for ACRE.  Crops are behind in maturity, some areas of the state need rain, product prices have fallen substantially, and USDA Counter Cyclical payments do not start until $2.35 on corn, $5.36 soybeans and $3.40 on wheat. Chances of prices that low are around 10-15%, but at that point ACRE payments would be much, much bigger.  Many producers do not understand ACRE and the benefits available; most of the reasons given for not participating are invalid.

OPTIMAL ROW WIDTH FOR CORN AND SOYBEAN
Provedor de dados: 31
Autores: Lambert,   Dayton M.; Lowenberg-DeBoer,   James.
Soybean production in narrow rows is not a novel idea.  Wiggans (1939) reported yield advantages of drilled soybeans in narrow rows (8-inches) over soybeans planted in 28-inch rows.  However, farmers, consultants, and extension agents face a bewildering array of information regarding optimal row widths intended to maximize return from corn and soybeans during a growing cycle.  This information is further complicated by the choices of planting equipment specialized for certain row widths.   That soybeans planted in narrow rows generally out-yield soybean produced in wider rows is well documented.  However, what is not clear is which narrow row width consistently and significantly outperforms other widths, yield-wise and return-wise, in which regions (Devlin...

The Economic Impact of Invasive Species in the Ornamental Commodity in Puerto Rico: Towards Establishing a Multidimensional Framework for Data Collection and Analysis
Provedor de dados: 31
Autores: Alamo,   Carmen I.; Franqui,   R.A.; Evans,   Edward A.
The ornamental commodity in Puerto Rico is valued for its economic contribution in the agricultural sector, its contribution to the esthetics of natural scenarios that impact the tourism sector, and for its environmental role. In the fiscal year 2001, ornamentals generated 4.8% of the total Agricultural Gross Product. In that year the production value at farm level was $34.1 million, the export value $0.5 million, and the import value $11.5 millions. Of the local production value, 1.5% was exported and 34.3% of the ornamental local market value was imported. The active trade traffic in Puerto Rico is a factor that increases the risk of the introduction of invasive species that affect the agricultural sector. It is necessary to estimate the economic impact...

Exports have been an integral and essential feature of the agriculture and food industry in Alberta. This is a product of the province’s relatively low population and consumption base on the demand side juxtaposed with a large resource base of prime agriculture land for crop production and an abundance of range and pasture for grazing and forage for raising livestock on the supply side. A host of factors influence the disposition of surplus production or exports including global supply/demand balances, relative cost/price relations, structural changes through farm consolidation and scale economies, market access, exchange rates, sanitary and phyto‐sanitary standards and regulations, disease and pest related issues. The inherent nature of agriculture means...

Using panel data econometric techniques and propensity score matching procedures, this study evaluates the impact of the MAUNLAD agricultural development program - a program designed to help alleviate poverty in Philippine coconut-producing communities.  Our results indicate that the program had a significant positive mean effect on the recipients' total net farm income.  Moreover, the probability of being in poverty is shown to decrease when a poor coconut producer participates in the program.  The program's emphasis on training, intercropping, and livestock integration, as well as the more participatory approach taken, contributed to the strong positive impact of the program.

The excessive use of pesticides in Indonesia during the 1970s and 1980s caused serious environmental problems such as acute and chronic human pesticide poisoning, animal poisoning and contaminated agricultural products, destruction of both beneficial natural parasites and pest predators, and pesticide resistance in pests.  To overcome these environmental problems, since 1989 the Indonesian government has actively adopted a strategy of integrated pest management (IPM).  During the first few years of the IPM program’'s implementation, the program has been able to help farmers reduce the use of pesticides by approximately 56 percent, and increase yields by approximately 10 percent.  However, economic literature that analyzes the impact of the IPM program on...

This report examines the likely effects of additional agricultural water rights under the Columbia River Initiative (CRI) on net crop revenues (hay, orchards, vegetables, potatoes, wheat, and other crops) in the state of Washington over the next 20 years. This study corrects for four potentially serious methodological flaws made in two previous studies associated with the CRI and concludes that those studies substantially overestimated the net revenues accruing to producers in the Columbia River area from new irrigated acreage under the CRI. In fact, the net revenues are more likely to be negative than positive. Methodological errors made in the two previous studies lead to results that support a policy prescription that is just the opposite of what would...

Urgent Need for Effective Public-Private Coordination in Zambia’s Cotton Sector. Deliberations on the Cotton Act.
Provedor de dados: 31
Autores: Tschirley,   David L.; Kabwe,   Stephen.
Cotton is an unquestioned success of Zambia’s turn towards a market economy. Yet the entry over the past two years of new players has put the sector under great stress and may have pushed it to a turning point. Now more than ever, effective “rules of the game” are urgently needed to protect Zambia’s remarkable cotton success story. Other countries in southern and eastern Africa have seen dramatic declines in input credit and extension to farmers, and in cotton quality, when competition among ginning firms intensified in the absence of suitable rules of the game. The focus in Zambia must be on establishing broadly accepted rules of the game that ensure honest competition that does not undermine input credit, extension, and cotton quality.

Improved Program Planning Approaches Generates Large Benefits in High Risk Crop Farming
Provedor de dados: 31
Autores: Musshoff,   Oliver; Hirschauer,   Norbert.
This paper examines whether there is room for the improvement of farm program decisions through the incorporation of mathematical optimization in the practical planning process. Probing the potential for improvement, we investigate the cases of four German cash crop farms over the last six years. The formal planning approach includes a systematic time series analysis of farmspecific single gross margins and a stochastic optimization model. In order to avoid solutions that simply exceed the farmer’'s risk tolerance, the apparently accepted variance of the observed program’'s total gross margin which represents an observable reflection of the individual farmer'’s risk attitude is used as an upper bound in the optimization. For each of the 24 planning...

VOLUNTARY ECONOMIC AND ENVIRONMENTAL RISK TRADEOFFS IN CROP PROTECTION DECISIONS
Provedor de dados: 31
Autores: Lohr,   Luanne; Park,   Timothy A.; Wetzstein,   Michael E.
An indirect utility model is employed for measuring farmers willingness to voluntarily accept yield losses for a reduction in environmental risk by decreasing pesticide use.  Results support the hypothesis that farmers have self-described risk perceptions that enable them to make assessments of risk-yield tradeoffs.  Policies designed to encourage and assist farmers making voluntary pesticide reductions can result in environmental risk reduction.

Factors Affecting Farmers’ Utilization of Agricultural Risk Management Tools: The Case of Crop Insurance, Forward Contracting, and Spreading Sales
Provedor de dados: 31
Autores: Velandia,   Margarita M.; Rejesus,   Roderick M.; Knight,   Thomas O.; Sherrick,   Bruce J.
Factors affecting the adoption of crop insurance, forward contracting, and spreading sales are analyzed using multivariate and multinomial probit approaches that account for simultaneous adoption and/or correlation among the three risk management adoption decisions. Our empirical results suggest that the decision to adopt crop insurance, forward contracting, and/or spreading sales are correlated. Richer insights can be drawn from our multivariate and multinomial probit analysis than from separate, single-equation probit estimation that assumes independence of adoption decisions. Some factors significantly affecting the adoption of the risk management tools analyzed are proportion of owned acres, off-farm income, education, age, and level of business risks.

Autores: Ethridge,   Don E.; Roy,   Sujit K.; Myers,   David W.
Markov chain analysis of changes in the number and size of cotton gin firms in West Texas was conducted assuming stationary and non-stationary transition probabilities.  Projections of industry structure were made to 1999 with stationary probability assumptions and six sets of assumed conditions for labor and energy costs and technological change in the non-stationary transition model.  Results indicate a continued decline in number of firms, but labor, energy, and technology conditions alter the configuration of the structural changes.

Romanian Maize - Distorted Prices and Producer Efficiency
Provedor de dados: 31
Autores: Sauer,   Johannes; Balint,   Borbala.
This research aims at shedding empirical light on the relative efficiency of small-scale maize producers in Romania. Farmers in transition countries still face heavily distorted price systems resulting from imperfect market conditions and socioeconomic and institutional constraints. To capture such distortions we formulate a stochastic shadow-cost frontier model to investigate the systematic input-specific allocative inefficiency. We further adjust the underlying cost frontier by incorporating shadow price corrections and subsequently reveal evidence on farm specific technical inefficiency. Different models are estimated due to the imposition of curvature correctness and the effects on the individual efficiency estimates are shown. The empirical results...

CROP DIVERSITY AS THE DERIVED OUTCOME OF FARMERS' 'SURVIVAL FIRST' MOTIVES IN ETHIOPIA: WHAT ROLE FOR ON-FARM CONSERVATION OF SORGHUM GENETIC RESOURCES?
Provedor de dados: 31
Autores: Wale,   Edilegnaw; Virchow,   Detlef.
Crop genetic resources are the building blocks of sustainable agricultural development due to their relevance not only as inputs for variety development but also as indigenous crop insurance mechanisms through traditional variety portfolio management. Their continuous survival is, however, threatened by natural and human driven factors. This threat has induced the need for designing conservation measures. Among the in situ and ex situ conservation options available to conserve crop genetic resources, on-farm conservation has recently attracted enormous attention. To make this option operational, placing incentives (that link conservation with utilization) and removal of perverse incentives are believed to be crucial so that landraces of no immediate...

Net Returns of Alternative Crops on Flood-Prone Land: Louisa County, Iowa, and Saline County Missouri
Provedor de dados: 31
Autores: Kruse,   John R.; Mitchell,   Paul D.; Bouzaher,   Aziz; Smith,   Darnell B.
The profitability of planting flood tolerant crops in flood plains relative to traditional row crops is evaluated under different assumptions concerning flood frequency and the level of government crop subsidy.  The alternative crops evaluated are short rotation woody crops and herbaceous energy crops.  The analysis is conducted for two growing environments: Louisa County, Iowa and Saline County. Missouri.  The economic indicator used to value the alternative scenarios is annualized net return per acre.  This indicator can account for the significant time lags between planting and harvesting of the two alternative crops.  The results indicate that row crops dominate the flood tolerant crops until flood frequency approaches 50 percent. The positive...

VARIATION IN MARGINAL RESPONSE TO NITROGEN FERTILIZER BETWEEN LOCATIONS

Autores: Graybeal,   Dale K.
A logistic growth equation with time and location varying parameters was used to model corn response to applied nitrogen. A nonlinear dummy-variable regression model provided a parsimonious representation of site and time effects on parameter values. The model was used to test for the equality of the mean marginal product of nitrogen fertilizer between locations on the coastal plain of North Carolina. Monte Carlo simulation and bootstrap simulation were used to construct finite sample covariance estimates. Results support rejection of the hypothesis that mean marginal products are equal when nitrogen is applied at 168 kg/ac. A comparison of bootstrapped errors and asymptotic errors suggests that results based on asymptotic theory are fairly reliable in...

Towards Quantifying The Economic Effects Of Poor And Fluctuating Water Quality On Irrigation Agriculture: A Case Study Of The Lower Vaal And Riet Rivers
Provedor de dados: 31
Autores: Armour,   R.J.; Viljoen,   Machiel F.
Irrigation farmers in the lower reaches of the Vaal and Riet Rivers are experiencing substantial yield reductions in certain crops and more profitable crops have been withdrawn from production, hypothesised, as a result of generally poor but especially fluctuating water quality. In this paper secondary data is used in a linear programming model to test this hypothesis by calculating the potential loss in farm level optimal returns. The model is static with a time frame of two production seasons. Linear crop-water quality production functions (Ayers &amp; Westcot, 1983; adapted from Maas &amp; Hoffmann, 1977) are used to calculate net returns for the eight most common crops grown. Results show optimal enterprise composition under various water quality...

Multifunctional agriculture is particularly fundamental to some working lands conservation policies and programs, such as the Environmental Quality Incentive Program (EQIP), Conservation Security Program (CSP) and Wildlife Habitat Incentive Program (WHIP). Farmers can also be engaged in providing recreational and agri-tourism services such as hunting, fishing, bird-watching, farm tours, petting zoos and hospitality services. Using the Agricultural Resource Management Survey (ARMS) we analyze factors associated with participation in conservation, recreation and agri-tourism activities as a function of farm structure, farm financial measures, production practices, and socio-demographic characteristics of the farm operator.

The call for school finance reform has threatened to modify or possibly remove the current property and sales and use tax exemptions currently benefiting Texas cotton producers. This study utilizes a whole farm simulation model to evaluate the economic and financial impact of three alternative sales and/or property tax policy changes on Texas cotton farms along with their respective landowners. Results indicate that removing sales tax exemptions would most adversely impact producers, while removing property tax exemptions has a more negative effect on landowners.

In particular, straw and stover total delivery costs, potential straw and stover supply sites and least cost transportation routes are identified using a linear programming transport model and a GIS (Geographic Information Systems) mapping system. We show that USDA/NRCS (Natural Resources Conservation Service) future crop residue removal rate policies will be important for determining whether it is economically viable to harvest crop residues as potential feedstock for energy generation. Increase in residue removal rates narrow the size of residue supply areas and consequently result in lowering...

In 1996, Bt cotton became one of the first genetically engineered crops to be available commercially.  This study focuses on the various sources and quality of information about Bt cotton profitability available to farmers in the Southeast and assesses the relative importance of such information in the farmers' adoption decisions.  A model of the individual decision to adopt is developed to incorporate two recent theories  of the role of information quality (the "effective information" hypothesis and the "popularity" hypothesis) as well as the effect of current technology depreciation.  The data show some support for all three factors as determinants of adoption.

What is the Difference in Profit per Acre between Organic and Conventional Coffee?
Provedor de dados: 31
Autores: Jensen,   Jennifer; Dicks,   Michael R.
The research addresses the economic problem of deforestation.  A contributing factor to deforestation is coffee production. Coffee is an indigenous plant that is naturally occurring in the native tropical forests. However, conventional coffee is grown on cleared forest soil. In the native forest there is the potential for additional fruits (bananas, mangoes, avocados) and wood products while in the conventional coffee production system the only product is coffee.  Conventional coffee production often causes deforestation and soil erosion while the organic coffee production system does not. In addition, the price risk associated with the coffee monoculture is high and has proven disastrous to the sustainability of coffee production in past years. Thus,...

The sugar industry is a major agro-based industry of Uttar Pradesh where cropping pattern is largely subsistence-oriented and sugarcane is one of the important cash crops. During 2001-02, the state had 20.35 lakh ha area under sugarcane out of the total 44.03 lakh ha area under sugarcane in the country. The sugar industry has shown considerable instability in the level of production as a result of inter-dependence and inter-relationship between sugarcane, gur, khandsari and white sugar, leading to fluctuations in the production of sugarcane as well as sugar. These fluctuations emanate from the presence of various processing sectors and the differential governmental policies. Such an uncertain state of affairs is neither conducive to sound growth of the...

In parallel with changes in official standards, supermarket chains in Europe have developed prescriptive, production-oriented standards, e.g. the European Union Retailers Produce Working Group for Good Agricultural Practices (GlobalGAP), and are asking their suppliers for produce to be certified according to food-safety and quality standards. There are concerns that the proliferation and enhanced stringency of standards that are imposed by high-income countries can negatively affect the competitiveness of producers in developing countries and impede actors from entering or even remaining in high-value food markets. Yet, in some cases, others argue that such standards can play a positive role, providing the catalyst and incentives for the modernization of...

A survey of 103 sugarcane farmers on the KwaZulu-Natal coast was conducted in order to analyse the impact of the Sectoral Determination for Farm Workers (2002) on South African agriculture. The sample was separated into a high wage paying North Coast and lower wage paying South Coast. Typically farmers were unable to distinguish between the impact of the Sectoral Determination and other labour laws. Results indicate that the impact of the legislation is similar in each region. No respondents reported mass retrenchment, but job shedding is disguised by not replacing workers (especially unskilled workers) that leave the farm. A sizeable number of growers (17 per cent on the South Coast and 44 per cent on the North Coast) have reduced the working week to 27...

Autores: Estes,   Edmund A.; Blakeslee,   Leroy L.; Mittelhammer,   Ronald C.
A 46-equation econometric model of the U.S. potato market was developed. The model examines the determination of planted acreage, yield, production, and farm prices in the Pacific Northwest and in five other producing regions which compete with Northwest production. National demand relationships for potatoes used in processing, fresh consumption and livestock feed are also specified. These estimated relationships are used to simulate future scenarios which assume alternative rates of expansion for Northwest potato production. Results suggest that opportunities for considerable expansion of Northwest potato production exist if the secular shift in potato demand continues and increases in acreage are not excessive or expansion does not occur too quickly.

Creating Carbon Offsets in Agriculture through No-Till Cultivation: A Meta-Analysis of Costs and Carbon Benefits
Provedor de dados: 31
Autores: Manley,   James G.; van Kooten,   G. Cornelis; Moeltner,   Klaus; Johnson,   Dale W.
Carbon terrestrial sinks are often seen as a low-cost alternative to fuel switching and reduced fossil fuel use for lowering atmospheric CO2. To determine whether this is true for agriculture, one meta-regression analysis (52 studies, 536 observations) examines the costs of switching from conventional tillage to no-till, while another (51 studies, 374 observations) compares carbon accumulation under the two practices. Costs per ton of carbon uptake are determined by combining the two results. The viability of agricultural carbon sinks is found to vary by region and crop, with no-till representing a low-cost option in some regions (costs of less than $10/tC), but a high-cost option in others (costs of $100-$400/tC). A particularly important finding is that...

Autores: Arandia Miura,   Amaia; Aldanondo-Ochoa,   Ana.
Organic farming may be seen as an alternative approach to agriculture that tries to integrate environmental concerns in management practices. By means of DEA, in this work we calculate and compare the efficiency of two samples of conventional and organic vineyards, from two different perspectives: in the first instance, the relationship between inputs and outputs is considered, exclusively, that is, the private efficiency; in the second instance, social efficiency is calculated, and the environmental impacts arising from the activity are also included. The comparison of the results obtained in these two scenarios allows us to draw some conclusions on the efficiency of organic farming in dry-farming conditions.

This study uses data from 1996/97 through 1998/99 to examine the relative efficiency of production of crops in Bangladesh and their comparative advantage in international trade as measured by net economic profitability (the profitability using economic, rather than financial costs and prices), and the domestic resource cost ratio, (the amount of value of non-tradable domestic resources used in production divided by the value of tradable products). The economic profitability analysis demonstrates that Bangladesh has a comparative advantage in domestic production of rice for import substitution. However, at the export parity price, economic profitability of rice is generally less than economic profitability of many non-rice crops, implying that Bangladesh...

A myriad of policy issues and questions revolve around understanding the bioeconomy. To gain insight, we develop a stochastic and dynamic general equilibrium model and capture the uncertain nature of key variables such as crude oil prices and commodity yields. We also incorporate acreage limitations on key feedstocks such as corn, soybeans, and switchgrass. We make standard assumptions that investors are rational and engage in biofuel production only if returns exceed what they can expect to earn from alternative investments. The Energy Independence and Security Act of 2007 mandates the use of 36 billion gallons of biofuels by 2022, with significant requirements for cellulosic biofuel and biodiesel production. We calculate the level of tax credits required...

FERTILIZER MARKET REFORM AND THE DETERMINANTS OF FERTILIZER USE IN BENIN AND MALAWI
Provedor de dados: 31
Autores: Minot,   Nicholas; Kherallah,   Mylene; Berry,   Philippe.
Most countries in sub-Saharan Africa have reduced or eliminated fertilizer subsidies and liberalized input marketing as part of the reform process that began in the early 1980s. The effect on fertilizer prices and use is one of the most frequently mentioned criticisms of liberalization. The effect of these reforms, however, has varied widely across countries. For example, in Benin fertilizer use has increased ten-fold since 1982, while in Malawi it has risen just 30 percent, less than population growth over the period. This paper explores the factors behind these widely different experiences with input market reform. It relies in part on household survey data collected by IFPRI and collaborating institutions in 1998. The two surveys used nationally...

Rabobank’s Success in Uncertain Times: An Executive Interview with Frans van Bijsterveld
Provedor de dados: 31
Autores: Hooper,   Richard.
The end of 2008 ushered in a severe and sweeping economic change throughout the global economy. In an Executive Interview conducted during IAMA’s 2009 World Forum and Symposium in Budapest, Hungary, Frans van Bijsterveld, Global Head of Food &amp; Agribusiness Research at Rabobank explains why Robobank is one of the few financial institutions that has not been heavily affected. Rabobank continues to remain successful in these uncertain times because of it’s careful selection of customers and sole focus on Food and Agribusiness (F&amp;A) outside of the Netherlands, as F&amp;A is typically far more resilient than other sectors.

Removing border protection on wheat and rice: effects on rural income and food self-sufficiency in China
Provedor de dados: 31
Autores: Mai,   Yinhua.
In this paper, I use the Monash Multi-Country model – a dynamic Computable General Equilibrium model of China, Australia and the Rest of the World – to analyse the effects of removing border protection on wheat and rice in China. The analysis points to the possibility that removing border protection on wheat and rice may lead to an increase in rural income in China. This is mainly due to the following two factors. First, removing border protection on wheat and rice not only leads to a contraction in agricultural activities, but also leads to an expansion in manufacturing and services activities. Second, on average, rural households in China obtain over half of their income from manufacturing and services activities.

DERIVED DEMAND FOR WHEAT BY CLASS
Provedor de dados: 31
Autores: Terry,   Justin J.; Marsh,   Thomas L.
To quantify price responsiveness and economic substitutability among wheat classes, derived demand functions were specified from a normalized quadratic profit function. Own-price and cross-price elasticities were estimated for hard red winter, hard red spring, soft wheat (combined red and white), and durum wheat. In general, soft wheat varieties were less responsive to their own price than were hard wheat varieties. Cross-price elasticities indicate that hard red winter wheat, hard red spring wheat, and soft wheat varieties are economic substitutes. Cross-price elasticities are different from those previously reported, which can have important policy implications.

Using a Farmer's Beta for Improved Estimation of Expected Yields
Provedor de dados: 31
Autores: Carriquiry,   Miguel A.; Babcock,   Bruce A.; Hart,   Chad E.
Effects of sampling error in estimation of farmers’ mean yields for crop insurance purposes and their implications for actuarial soundness are explored using farm-level corn yield data in Iowa. Results indicate that sampling error, combined with nonlinearities in the indemnity function, leads to empirically estimated insurance rates that exceed actuarially fair values. The difference depends on the coverage level, the number of observations used, and the participation strategy followed by farmers. A new estimator for mean yields based on the decomposition of farm yields into systemic and idiosyncratic components is proposed, which could lead to improved rate-making and reduce adverse selection.

AN ECONOMIC ANALYSIS OF CORN YIELD, CORN PROFITABILITY, AND RISK AT THE EDGE OF THE CORN BELT
Provedor de dados: 31
Autores: Chavas,   Jean-Paul; Kim,   Kwansoo; Lauer,   Joseph G.; Klemme,   Richard M.; Bland,   William L.
This study investigates the recent evolution of corn yield, with a special focus on the tradeoff between corn profitability and risk.  The analysis relies on time-series data from Wisconsin experimental farms at the edge of the Corn Belt.  An econometric model of corn yield, corn grain moisture, and corn profitability is specified.  Both conditional means and conditional variances are estimated for different sites in Wisconsin. The empirical analysis shows the changes in corn yield and profit over time and across space.  The evidence suggests that yield trends are due mostly to technical progress, with smaller effects generated by climate change.  On average, corn yield and profitability have improved faster in northern Wisconsin than in the Corn Belt....

Economic and Marketing Efficiency Among Corn Ethanol Plants
Provedor de dados: 31
Autores: Sesmero,   Juan P.; Perrin,   Richard K.; Fulginiti,   Lilyan E.
We extend data envelopment analysis (DEA) to decompose the economic efficiency of a sample of ethanol plants into internal (technical and allocative) and boundary (marketing) sources. This decomposition allows us to evaluate the channels through which different plant characteristics affect plant performance. Results show that plants are very efficient from a technical point of view. Plants with higher production volumes seem to perform better not because of economies of scale but because they can secure more favorable prices (higher marketing efficiency) and execute production plans accordingly (higher allocative efficiency). This may rationalize the increase in the size of the average plant observed in the industry in recent years despite evidence of...

PRECISION AGRICULTURE: ECONOMICS OF NITROGEN MANAGEMENT IN CORN USING SITE-SPECIFIC CROP RESPONSE ESTIMATES FROM A SPATIAL REGRESSION MODEL
Provedor de dados: 31
Autores: Bongiovanni,   Rodolfo; Lowenberg-DeBoer,   James.
Adapting variable rate technology (VRT) to Argentine conditions requires methods that use inexpensive information and that focus on the inputs and variability common to Argentine maize and soybean growing areas.  The goal of this study is to determine if spatial regression analysis of yield monitor data can be used to estimate the site-specific crop Nitrogen (N) response needed to fine tune variable rate fertilizer strategies.  N has been chosen as the focus of this study because it is the most commonly used fertilizer by corn farmers in Argentina.  The methodology uses yield monitor data from on-farm trials to estimate site-specific crop response functions.  The design involves a strip trial with a uniform N rate along the strip and a randomized complete...

Autores: Wanzala,   Maria N.; Jayne,   Thomas S.; Staatz,   John M.; Mugera,   Amin W.; Kirimi,   Justus; Owuor,   Joseph.
The paper has several specific objectives. First, it identifies how fertilizer marketing costs and the types of fertilizers used have changed over the course of the liberalization process in Kenya. A second objective is to examine the fertilizer subsector in Kenya with a view to identifying organizational and institutional changes that could improve its performance. Various types of fertilizer supply chains serving farmers in western Kenya are identified, examine the cost structure of these supply chains, identify potential sources of cost reduction in these supply chains, and last, estimate the impact of illustrative scenarios for reducing fertilizer marketing costs on the profitability of maize production in western Kenya.

THE ROLE OF SMALL RICE MILLS IN THE RICE SUBSECTOR OF THE OFFICE DU NIGER, MALI
Provedor de dados: 31
Autores: Diarra,   Salifou Bakary.
The presence of the small rice mills in the Office du Niger zone has changed the structure of the rice subsector, helping to reduce concentration and changing marketing options of both farmers and retailers. Current proposals call for major initiative to liberalize the rice market further and to shift the principal role of the O.N. toward provision of water and extension. In this context, it is extremely important to investigate the role of small mills in the subsector, their relative costs, and the segments of the market they serve.  Budgeting techniques were used to analyze milling cost data. Price data were used to calculate both correlation coefficients and spatial marketing margins. The analyses of correlation and calculation of spatial margins...

This paper is based on a survey of thirty-one market actors from producing and consumption markets in Kenya. The data was collected through personal interviews. In analyzing integration of p ineapple markets we use Ravallion-type model. Results show that pineapple market in Kenya is oligopsonistic in nature with aspects of collusion amongst the urban middlemen and local market traders thus barring further entry by oth er potential actors. There was little market integration between urban markets and producing markets, and no integration between the rural producing markets. However, model results show that information flow between production and consumption markets significantly influence market integration, an indicator for efficiency in resource...

Does a Rising Biofuels Tide Raise All Boats? A Study of Cash Rent Determinants for Iowa Farmland under Hay and Pasture
Provedor de dados: 31
Autores: Du,   Xiaodong; Hennessy,   David A.; Edwards,   William M.
Iowa’s farmland consists of over 16% hay crops and pastureland, a significant portion of which is under cash rental contracts. This study investigates the comparative relationships between cash rental rates for cropped land and non-cropped land, where the latter includes hay and pastureland. We find that higher crop prices resulting from biofuel demand induces land use conversion from non-cropped land to crop production and thus bids up non-cropped land rents. Compared with changes in cropped land cash rents, non-cropped farmland rents could increase by a higher percentage. Non-cropped land cash rental rates are largely determined by crop and feeder cattle prices, population density, soil quality, and proportion of non-cropped land in a specific area. A...

A regime-switching model for analysis of market integration has been developed that incorporates rate of trade information. An application of the methods to United States–China soybean trade demonstrates that the extended trade information allows better interpretation of market conditions. While the empirical results show that China’s reform efforts since mid 1990s toward an open market have greatly improved United States–China soybean markets integration, about 40% of nontransitional disequilibrium occurrences likely indicate infrastructural limits such as the lack of information availability and limited competition. The United States–China price linkage is observed to be closer after China’s World Trade Organization membership. The link has also been...

A diffusion model for the adoption of agricultural innovations in structured adopting populations
Provedor de dados: 31
Autores: McRoberts,   Neil; Franke,   A.C.
We introduce a new model for examining the dynamics of uptake of technological innovations in agricultural systems, using the adoption of zero-till wheat in the rice-wheat system in Haryana state, India, as a case study. A new equation is derived which describes the dynamics of adoption over time and takes into account the effect of aggregation (e.g. on a spatial and/or cultural basis) in the adopting population on the rate of adoption. The model extends previous phenomenological models by removing the assumption of homogeneity in the non-adopting fraction of the population. We show how factors affecting the per capita rate of adoption can be captured using cognitive mapping and simulate the dynamics of the adoption process.

The adoption of organic production has increased dramatically over recent years, especially in less developed countries. However, little information is available about who adopts, the difficulties they face in converting and how these factors vary over time. Using small-scale avocado producers (&lt;15ha) from Michoacán, Mexico as a case study, this paper explores the factors affecting the time-to-adoption of organic production and certification, drawing from five parametric descriptions of the data. These models are implemented using a Bayesian approach and advances in Markov chain Monte Carlo methods.

Using the Ricardian Technique to estimate the impacts of climate change on Crop Farming in Pakistan
Provedor de dados: 31
Autores: Ahmed,   Mirza Nomman; Schmitz,   P. Michael.
This study uses the Ricardian valuation technique to estimate the effect of climate change on the crop farming sector in Pakistan. As a main contribution this paper uses a large household level dataset comprising 3336 farming entities to analyze long-term climate impacts on farm net crop revenues. In particular temperature increases in key growing seasons can be harmful. Annual losses for crop farming ranging from 100-200US$ can be expected. Given an average crop net income of 450US$ per hectare, these impacts can be devastating for farmers. The climate impacts will vary across geographic regions. Temperature is found to be the detrimental factor for farming in Pakistan. Precipitation changes seem to have a rather negligible effect.

The paper investigates the linkages between technological change and production risk, with an application to corn. The effects of technology on risk exposure are characterized based on the properties of the risk premium. We define technological progress to be risk-increasing (risk-decreasing) if it increases (decreases) the relative risk premium. The analysis is applied to panel data from Wisconsin research stations. Conditional moments (including mean, variance and skewness) of corn yield, grain moisture and corn profit are estimated for different sites. We investigate how the trade-off between expected return and the risk premium varies over time and over space. The empirical results indicate that technological progress contributes to reducing the...

A hedonic approach to estimating the supply of variety attributes of a subsistence crop
Provedor de dados: 31
Autores: Edmeades,   Svetlana.
The paper extends the household hedonic model, as a non-market valuation tool, by estimating a supply function for variety attributes of a subsistence crop in a developing country. The model is applied to bananas in Uganda, making use of disaggregated data on variety-specific farm-gate banana bunch prices and attributes. The hedonic analysis is applied at the farm-gate, the first link in the market chain, while accounting for the semi-subsistence nature of banana producing households. Within the framework of the agricultural household, where consumption and production decisions are non-separable, prices reflect the implicit marginal valuation of both consumption and production attributes jointly. The paper is motivated by the need to quantify the value of...

Demand for Drought Tolerance in Africa: Selection of Drought Tolerant Maize Seed using Framed Field Experiments
Provedor de dados: 31
Autores: Dalton,   Timothy J.; Yesuf,   Mahmud; Muhammad,   Lutta.
Recent projections on the impact of climate change argue that eastern and southern Africa will be two regions around the globe that will experience dramatic reductions in maize yields by mid‐century. Absent from these projections is any consideration for farmer adaptation of cropping practices or land reallocation. This research quantifies risk, loss and ambiguity aversion for a sample of smallholder Kenyan farmers using framed field experiments. This behavioral information, directly elicited, is used to condition the selection of maize varieties differentiated by drought tolerance, pest resistance, maturity, and seed price. Overall, the willingness to pay for drought tolerance and other attributes is highly heterogeneous as determined through a Latent...

Provedor de dados: 31
Autores: Ziegelback,   Martin; Kastner,   Gregor.
For European operators of biofuels plants there are not many hedge vehicles available to hedge operational margins. Cross hedges for rapeoil (with the rapeseed futures contract) and RME (with the NYMEX diesel futures contract) could be useful instruments. We use recent developments on threshold cointegration approaches to investigate if asymmetric dynamic adjusting processes exist among rapeseed and diesel prices. The results suggest that a threeregime threshold cointegration model suitably explains the dynamics of the data.

PREDATOR-PREY SYSTEMS IN PEST MANAGEMENT
Provedor de dados: 31
Autores: Harper,   Carolyn R.
The use of chemical pesticides frequently causes minor pests to become serious problems by disturbing the natural controls that keep them in check.  As a result, it is possible to suffer heavier crop losses after pesticides are introduced than before their introduction.  Efficient use of pesticides requires complete biological modeling that takes the appropriate predator-prey relationships into account.  A bioeconomic model is introduced involving three key species: a primary target pest, a secondary pest, and a natural enemy of the secondary pest.  Optimal decision rules are derived and contrasted with myopic decision making, which treats the predator-prey system as an externality.  The issue of resistance in the secondary pest is examined briefly.

The cost of segregating GM canola: A case study
Provedor de dados: 31
Autores: Hatwell,   Bronwyn; Pluske,   Johanna M.
The Gene Technology Regulator's approval of Bayer CropScience's genetically modified (GM) canola variety, InVigor, and Monsanto's Roundup Ready, means that the commercial planting of Australia's first GM food crop is imminent. Under such circumstances, for Australia to continue marketing non-GM canola and comply with worldwide labelling requirements segregation must be implemented. This study investigates the cost effectiveness of three possible segregation methods. In considering each of these methods the increase in total grain handling cost due to segregation is expected to be between 5 and 9 per cent, or $1.35/tonne and $2.70/tonne. Such an increase is comparable with segregation costs reported in current Canadian literature.

Autores: de Cara,   Stephane; Jacquet,   Florence; Reynaud,   Arnaud; Goulevant,   Gael; Jeuffroy,   Marie-Helene; Lucas,   Philippe; Montfort,   Francoise.
This paper addresses the question of summer cover crop adoption by farmers in presence of a risk of yield loss due to take-all disease and climate variability. To analyse the public incentives needed to encourage farmers to adopt summer cover crops as a means of reducing N leaching, we combine outputs from an economic, an epidemiological and an agronomic model. The economic model is a simple model of choice under uncertainty. The farmer is assumed to choose among a range of summer fallow managements and input uses on the basis of the expected utility criterion (HARA assumption) in presence of both climate and take all risks. The epidemiological model proposed by Ennaïfar et al. [1] is used to determine the impact of take all on yields and N-uptake. The...

Assessing the Impact of Cowpea and Sorghum Research and Extension in Northern Cameroon
Provedor de dados: 31
Autores: Sterns,   James A.; Bernsten,   Richard H.
Throughout Africa, per capita food production has been declining since the early 1960s. Cameroon has sought to counter this trend by increasing agricultural productivity through research and extension. In order to establish future investment priorities, policy makers need to know if past agricultural research investments have earned sufficient returns to justify continued funding. Further, national experiences need to be compared to see if returns varied across programs, and in cases where they did, explanations need to be sought to discover why these variations exist. To address these issues, data were collected in Cameroon and analyzed in order to estimate the benefits and costs of investments in sorghum and cowpea research and extension in northern...

Best fit model selection for spatial differences (regression) in the profitability analysis of precision phosphate (P) application to winter cereals in Precision Agriculture (PA)
Provedor de dados: 31
Autores: Hough,   Ella Christina; Nell,   Wilhelm T.; Maine,   Ntsikane; Groenewald,   Jan A.; van der Rijst,   M.
Phosphates (P) are an important nutrient required by every living plant and animal cell, and deficiencies in soils could cause limited crop production, thereby reducing profitability. Phosphates are also a primary nutrient essential for root development and crop production, and are needed in the tissues of a plant where cells rapidly divide and enlarge. Precision agriculture (PA) could assist the farmer in applying the correct amount of P to the part of the field where it is required most. Variable rate technology (VRT) is a potential tool that can help with the development of strategies for phosphate fertilizer management. On-field trials were conducted on a commercial farm in the Western Cape Province; As many as five soil types occur on each field...

Optimal crop protection against climate risk in a dynamic cost-loss decision-making model
Provedor de dados: 31
Autores: Quiroga,   Sonia; Cerda,   Emilio.
Extreme meteorological events have increased over the last decade and it is widely accepted that it is due to climate change. Some of these extremes like drought or frost episodes largely affect agricultural outputs that could face a serious decline. Therefore, additional efforts on technology and adaptation become crucial to reduce the effect of climate change on agricultural production. Protection against adverse weather extremes is a significant component of risk management and large protection decisions need dynamic treatment, such as the vineyards or citrus protection against frost (Murphy et al., 1985), the water management for cereals irrigation in drought shortage contexts, the “options and futures” exchange markets decisions for major crops in...

AN EMPIRICAL BARGAINING MODEL OF PRICE DISCOVERY: AN APPLICATION TO THE WASHINGTON/OREGON ASPARAGUS INDUSTRY
Provedor de dados: 31
Autores: Folwell,   Raymond J.; Mittelhammer,   Ronald C.; Wang,   Q.
The bargaining process and its role in price discovery within the Pacific Northwest asparagus industry is analyzed using a general empirical bargaining model.  Growers' and processors' inverse supply and demand functions define boundaries for the negotiated prices.  OLS and Heckman's two-stage estimation procedures are used to estimate a stochastic bargaining model of price determination.  The results indicate that basic supply and demand forces exert substantial influences on the bargaining process.  In particular, expected levels of supply play a paramount role in the level of prices offered, while past prices also influence current offers.  The general framework of analysis used in relation to asparagus can be generalized to other commodities where...

The Economics of Nested Insurance: The Case of SURE
Provedor de dados: 31
Autores: Cooper,   Joseph C.; Sproul,   Thomas W.; Zilberman,   David.
Traditionally, disaster assistance was available on an ad hoc basis, but the 2008 Farm Act provides a standing disaster assistance program known as Supplemental Revenue Assistance (SURE). This paper introduces a theory of nested insurance to evaluate the impact on of SURE on intensification, acreage and adoption. The results suggest that parameters of a government program like SURE may enhance the adoption and value of crop insurance to the farm sector. A quantitative understanding of the interdependencies between programs like SURE and crop insurance, taking into account the nature of the ad hoc alternative, is important in assessing the welfare impacts on farmers, as well as insurance companies. Both our theory and simulation exercise suggest that...

Transition, development and the supply of wheat in China
Provedor de dados: 31
Autores: Rozelle,   Scott; Huang,   Jikun.
The overall goal of this article is to better understand the factors that influence China’s wheat supply. We assess trends in China’s wheat output and develop a framework to measure the relationship between output and key determinants of China’s wheat sector growth. Elasticity estimates and factor growth trends help decompose the growth of reform‐era wheat supply into its component parts. The results show that growth in the early reform period was due to institutional change and technology. In the late reform period, however, with the returns to institutional change exhausted, all of China’s growth in wheat supply was due to technology, a result that implies China’s government should invest heavily in agricultural research and development.

Autores: Egelkraut,   Thorsten M.; Garcia,   Philip; Irwin,   Scott H.; Good,   Darrel L.
Using 1971-2000 data, we examine the accuracy of corn and soybean production forecasts provided by the USDA and two private services. All agencies improved their forecasts as the harvest progressed, and forecast errors across the agencies were highly correlated. Relative accuracy varied by crop and month. In corn, USDA 's forecasts ranked as most accurate in all periods except in August during recent times, and improved more markedly as harvest progressed. In soybeans, forecast errors were very similar with the private agencies ranking as most accurate in August and September and making largest relative improvements in August during recent times. The USDA provided the most accurate October and November forecasts.

PROBABILITY DISTRIBUTIONS OF CROP PRICES, YIELDS, AND GROSS REVENUE
Provedor de dados: 31
Autores: Tew,   Bernard V.; Reid,   Donald W.
This study shows that the price-yield correlation is a major influence in determining the skewness of revenue.  Therefore, normality for revenue may not be rejected even if the price and/or yield distributions are significantly skewed.  Analysis of cotton revenue for Mississippi shows that this can be the case empirically when the correlation between price and yield is moderately negative and the relative variability of yield and price is not too high.  Hence, for crops produced in their major production regions where negative correlations between prices and yields are the greatest, revenue distributions may have a greater tendency toward normal.

Florida ranked ninth in the U.S. in agricultural receipts for the year 2000, and ranked first or second in receipts for 12 of the nation's top 25 agricultural commodities. Ten of these twelve leading agricultural commodities were fresh fruits or vegetables, and combined, they represented over 45 percent of the state's agricultural receipts in 2000. Despite Florida's preeminent standing as a producer of fresh fruits and vegetables, it's future leadership in this industry is less clear. In real terms, Florida's annual agricultural receipts have declined from $7.41 billion in 1992, to $6.42 billion in 2001. In 2000, receipts fell by over $521 million, the sharpest one-year drop since 1990. The overall trend in fresh vegetable receipts for the State has been...

Autores: Walshe,   Kim.
This paper evaluates changes in the fisheries regulation environment in New Zealand’s marine fisheries from 1970 to 2003. The quota management system was heralded as the introduction of a market based reform, with a move away from input controls to output controls. The QMS impacted primarily on the commercial sector but also the recreational sector. It was hypothesized (by policy advisors and policy makers) that the QMS would lead to less government intervention and less regulation for the commercial sector. The paper presents findings that suggest the expectations of policy makers may have been misplaced.

Competitiveness of Kenyan and Ugandan Maize Production: Challenges for the Future
Provedor de dados: 31
Autores: Nyoro,   James K.; Kirimi,   Lilian; Jayne,   Thomas S.
The purpose of this study is to assess the costs of maize production in Kenya and Uganda, starting from the fact that there is no single “cost of production” for maize. Cost of production varies according to region, the type of technology package employed, farmers’ management practices, and the weather. In light of this, the study disaggregates cost of production into seven region/technology categories, five in Kenya and two in eastern Uganda, in order to compare the relative competitiveness of maize among these regions and technology packages. Variations in cost of production within each region/technology category reflect differences in farmer management practices and micro-variability in soils and rainfall.

The grain system (grain producers and the grain industry) in Michigan finds itself in a transition period. Production (yield) and price limitations along with escalating cost factors have left producers in a situation where, without government assistance, many more would have to exit the farm. The grain industry (in this study, the industry refers to the grain handlers and processors), while in a stronger financial situation than producers, would suffer negatively if volume of grains bought and sold through their facilities decreased, and more in the industry would have to exit.  A transition is needed to increase profitability of grain producers and the grain handlers and processors in Michigan. Without a transition, the trend of decreasing farms and...

DETERMINING OPTIMAL FERTILIZATION RATES UNDER VARIABLE WEATHER CONDITIONS
Provedor de dados: 31
Autores: Talpaz,   Hovav; Taylor,   C. Robert.
This paper presents a theoretical framework for incorporating the following sources of risk into the determination of optimal fertilization rates: (a) the influence of weather and other stochastic factors on the marginal product of fertilizer, and (b) uncertainty about the coefficients of the response function. The decision criterion considered is the maximization of profit subject to a risk constraint on the probability of not recovering the cost of the fertilizer. The theoretical framework is applied to the fertilization of dryland grain sorghum in the Texas Blacklands. Results indicate that the risk averse producer should substantially lower his fertilization rate if soil moisture at fertilization time is low.

The Causality Between U.S.A. and Australian Wheat Prices
Provedor de dados: 31
Autores: Sniekers,   Peter; Wong,   Gordon.
It has been generally agreed that Australia is a price follower on the world wheat market. However, to date, this has not been tested empirically. In this paper a transfer function model between prices of U.S.A. wheat and Australian wheat is set up to examine the existence, if any, of a leader-follower relationship. By employing the causality criteria as described by Granger, this analysis is implemented to draw inferences about causality among these wheat prices. Results indicated that a significant leader-follower relationship exists, with the U.S.A. taking the leader role. The results reported are particularly useful for wheat price forecasting work and provide a basis for further modelling work.

An Examination of the Relationship Between Subsidies on Production and Technical Efficiency in Agriculture: The Case of Cotton Producers in Greece
Provedor de dados: 31
Autores: Emvalomatis,   Grigorios; Oude Lansink,   Alfons G.J.M.; Stefanou,   Spiro E.
Subsidies on production have long been criticized for protecting producers from competition, and thus removing an incentive for efficient use of the resources. This study undertakes the examination of the impact of partially decoupled subsidies on the technical efficiency scores of cotton producers in Greece. The results indicate that compensatory area payments reduce the efficiency scores of the producers by diverting resources from products for which the subsidy is based on the area planted to the production of cotton, for which the aid is related to the volume of output.

A national pesticide-use survey from sorghum producers and a survey of entomologists and weed scientists were used to determine the impacts of pesticide use on sorghum. A market framework was employed to derive the short-run welfare impacts to consumers and producers (users and non-users) of the removal of pesticides currently registered for use on sorghum. It was projected that the loss of atrazine, the most widely used pesticide in sorghum production, would have the largest overall impact, with an estimated total welfare loss between $58 and $65 million.

Early-warning systems for plant diseases are valuable when the systems provide timely forecasts that farmers can use to inform their pest management decisions. To evaluate the value of the systems, this study examines, as a case study, USDA’s coordinated framework for soybean rust surveillance, reporting, prediction, and management, which was developed before the 2005 growing season. The framework’s linchpin is a website that provides real-time, county-level information on the spread of the disease. The study assesses the value of the information tool to farmers and factors that influence that value. The information’s value depends most heavily on farmers’ perceptions of the forecast’s accuracy. The study finds that the framework’s information is valuable...

Cropping pattern in the Himalayan region of India has undergone a significant change in the recent past. Introduction of horticultural crops of vegetables, fruits and flowers have led to more intensive agriculture. Such a change, resulting in higher incomes and improvements of the overall living conditions has, however, been accompanied with increased income risk. This emphasises a need for proper analysis of the cropping pattern, at an appropriate scale, such as, a micro watershed. This was achieved by constructing a dynamic non-linear programming model incorporating appropriate objective function, constraints and crop and livestock activity budgets along with risk component present in the gross returns. The model was then solved under alternate policy...

COST OF SEGREGATING NON-TRANSGENIC GRAINS AT COUNTRY ELEVATORS IN SOUTH DAKOTA
Provedor de dados: 31
Autores: Qasmi,   Bashir A.; Van der Sluis,   Evert; Wilhelm,   Clayton J.
Genetically modified grains have rapidly become popular among producers across U.S.  Some consumers, particularly in the EU, South Korea, and Japan, are unwilling to purchase products containing ingredients from genetically modified or transgenic crops.  This paper develops a model to represent costs of segregating non-transgenic grains at country elevators and simulates these costs at representative elevators in South Dakota under alternative scenarios employing a case study approach. The overall cost of segregating non-transgenic grains under a zero rejection rate ranged from 1.5 to 21.7, 1.2 to 11.3, and 1.3 to 16.4 cents per bushel, for corn, soybeans, and wheat, respectively.

SETOR SUCROALCOOLEIRO DE ALAGOAS: A ULTRA-ESPECIALIZAÇÃO COMO ESTRATÉGIA COMPETITIVA (1990/2008)
Provedor de dados: 31
Autores: Carvalho,   Cicero Pericles.
A primeira década desde o fim do IAA (1990/1999) ficou marcada, para o setor sucroalcoleiro nordestino, pela liberação do mercado de açúcar e álcool. No mesmo período esse setor desenvolveu, em Alagoas, um processo de reestruturação produtiva que, adotando novas estratégias competitivas, conseguiu superar tanto as adversidades de um mercado recentemente desregulamentado como as dificuldades decorrentes do novo ambiente institucional. Na década subseqüente (2000/2008), esse processo vem apresentando novidades. Apesar da pressão pela adoção de propostas de diversificação produtiva, o setor reafirmou a estratégia empresarial e o foco de negócio no sentido do crescimento especializado da produção: aperfeiçoou sua matriz produtiva com alguns novos itens,...

Coping with the “Coffee Crisis” in Central America: The Role of the Nicaraguan Red de Protección Social
Provedor de dados: 31
Autores: Maluccio,   John A.
The international and local Nicaraguan media have widely reported on the “coffee crisis” in Latin America and there is substantial evidence that there has been a downturn and that this has been more severe in the coffee-growing regions. Using household panel data from a randomized community-based intervention carried out in both coffee- and noncoffee-growing areas, I examine the role of a conditional cash transfer program, the Red de Protección Social (RPS), during this downturn. While not designed as a traditional safety net program in the sense of reacting or adjusting to crises or shocks, RPS has performed like one, with larger estimated program effects for those who were more severely affected by the downturn. For example, it protected households...

Climate change impacts on hydrology and water resources of the Upper Blue Nile River Basin, Ethiopia
Provedor de dados: 31
Autores: Kim,   Ungtae; Kaluarachchi,   Jagath J.; Smakhtin,   Vladimir U.
The report evaluates the impacts of climate change on the hydrological regime and water resources of the Blue Nile River Basin in Ethiopia. It starts from the construction of the climate change scenarios based on the outcomes of several general circulation models (GCMs), uses a simple hydrological model to convert theses scenarios into runoff, and examines the impacts by means of a set of indices. The results, however uncertain with existing accuracy of climate models, suggest that the region is likely to have the future potential to produce hydropower, increase flow duration, and increase water storage capacity without affecting outflows to the riparian countries in the 2050s.

Zambia's Stop-And-Go Revolution: The Impact of Policies and Organizations on the Development and Spread of Maize Technology
Provedor de dados: 31
Autores: Howard,   Julie A.; Mungoma,   Catherine.
This paper explores how Zambia's policy and organizational environment has shaped the development, spread, and more recently, the disadoption of maize technology. It also traces the political motivations that drove the establishment of the policy and organizational framework supporting maize production and impeded the efficient operation of the parastatal-managed marketing system. Options facing Zambian policy makers for increasing food production under evolving political and economic conditions are discussed in the light of these experiences.

AN ANALYSIS OF CONSTRAINTS ON EXPANDING RICE OUTPUT IN THE CASAMANCE REGION OF SENEGAL
Provedor de dados: 31
Autores: Rigoulot,   Jean Pierre.
Senegal imports about 200,000 tons of rice annually.  These import consume a large share of the national budget and represent a heavy outflow of foreign exchange.  Despite the implementation of various agricultural projects aimed at increasing domestic rice production, Senegal still relies on imports to fill its deficit and there is no evidence that the situation will change in the near future. The purpose of this paper is to identify and analyze selected factors which are believed to impede expansion of rice production in the Casamance (southern) region of Senegal.  The following factors are studied:  1)  climatic uncertainties (effects of the drought); 2)  the competition between groundnuts and rice for the allocation of family labor; 3)  the...

Positive Analysis of Invasive Species Control as a Dynamic Spatial Process
Provedor de dados: 31
Autores: Buyuktahtakin,   Esra; Feng,   Zhuo; Olsson,   Aaryn; Frisvold,   George B.; Szidarovszky,   Ferenc.
This paper models control of invasive buffelgrass (Pennisetum ciliare), a fire-prone African bunchgrass spreading rapidly across the southern Arizona desert as a spatial dynamic process. Buffelgrass spreads over a gridded landscape. Weed carrying capacity, treatment costs, and damages vary over grid cells. Damage from buffelgrass depends on its spatial  distribution in relation to valued resources. We conduct positive analysis of recommended heuristic strategies for buffelgrass control, evaluating their ability to prevent weed establishment and to reduce damage indices over time. The high dimensionality of the problem makes full dynamic optimization intractable. However, two heuristic strategies – potential damage weighting and consecutive year treatment –...

Grain Marketing Strategies Within and Across Lifetimes
Provedor de dados: 31
Autores: Peterson,   Hikaru Hanawa; Tomek,   William G.
To reconcile the discrepancy between the efficient market hypothesis and grain marketing recommendations by advisory services and extension programs, simulated prices from an efficient market are used to compare performance of marketing practices over the long run and in individual 40-year periods. We find that an efficient market can generate diverse price behavior within finite samples, allowing for strategies that are inferior on average to perform relatively better, as frequently as half of the time in an average 40-year lifetime. Lifetime returns of strategies show considerable overlap, suggesting extremely low confidence in recommendations made based on short samples.

Recommendations on Sample Design for Post-Harvest Surveys in Zambia Based on the 2000 Census
Provedor de dados: 31
Autores: Megill,   David J.
The Central Statistical Office (CSO) has been conducting the annual Zambia Post-Harvest Survey (PHS) for many years. The current sampling frame for this survey is based on the census supervisory areas (CSAs) and standard enumeration areas (SEAs) defined for the 1990 Zambia Census of Population and Housing. A new listing of households is conducted in the sample SEAs each year for selecting the sample households. Although this is still a representative sample of households, changes in the population distribution during the past decade have made the 1990 sampling frame for the PHS less efficient. Now that the data from the 2000 Zambia Census of Population and Housing are available, it is possible to develop a more effective sampling frame for the PHS. The...

Social Costs of Herbicide Resistance: The Case of Resistance to Glyphosate
Provedor de dados: 31
Autores: Marsh,   Sally P.; Llewellyn,   Rick S.; Powles,   Stephen B.
Unlike in the pesticide and antibiotic resistance literature, potential social costs and externalities associated with herbicide resistance have not generally been considered by economists. The economics of managing herbicide resistance in weeds has focused on cost-effective responses by growers to the development of resistance at the individual farm and field level. Economic analyses of optimal herbicide use have focused on optimising farmer returns in the long run. Weeds have been considered less mobile, compared to insects and diseases, suggesting that externalities resulting from resistance spread will be minimal and any consequent social costs low. Glyphosate is the world's most widely used broad-spectrum non-selective herbicide. Declining glyphosate...

Farmers’ Willingness to Grow Switchgrass as a Cellulosic Bioenergy Crop: A Stated Choice Approach
Provedor de dados: 31
Autores: Fewell,   Jason E.; Bergtold,   Jason S.; Williams,   Jeffery R.
Farmers’ Willingness to Grow Switchgrass as a Cellulosic Bioenergy Crop:  A Stated Choice Approach  Agriculture’s role as a source of feedstocks in a potential lignocellulosic-based biofuel industry is a critical economic issue. Several studies have assessed the technical feasibility of producing bioenergy crops on agricultural lands. However, few of these studies have assessed farmers’ willingness to produce or supply bioenergy crops or crop residues. Biomass markets for bioenergy crops do not exist, and developing these markets may take several years. Therefore, an important, yet unaddressed question is under what contractual or pricing arrangements farmers will grow biomass for bioenergy in these nascent markets.  The purpose of this paper is to examine...

This report evaluates the U.S. and world sugar markets for 2004-2013 using the Global Sugar Policy Simulation Model.  This analysis is based on assumptions about general economic conditions, agricultural policies, population growth, weather conditions, and technological changes. Both the U.S. and world sugar economies are predicted to improve slightly over the next nine years after the current over-supply is reduced.  World demand for sugar is expected to grow faster than world supply, resulting in Caribbean sugar prices gradually increasing from 8.40 cents/lb in 2004 to 8.70 cents/lb in 2013.  The U.S. wholesale price of sugar is projected to decrease from 26.15 cents/lb in 2004 to 24.89 cents/lb in 2013, if the United States maintains its sugar programs....

This paper investigates the roles of industrial cluster on the efficiency of rice milling and the improvement of milled rice quality. The data were obtained in Kumasi area, central Ghana because the enhancement of domestic rice production is a urgent policy issue in this country, but little attention has been paid to the roles of clusters in post-harvest processing and marketing. Among 63 rice millers interviewed in the Kumasi area, 24 millers form a few clusters in the city of Kumasi, while others are scattered over 25 satellite towns around Kumasi, which enables us to examine the effect of the cluster. Regression analyses reveal that rice millers in the Kumasi clusters tend to adopt more advanced technology, and that the innovation increases milling...

ECONOMIC AND HYDROLOGIC IMPLICATIONS OF SUSPENDING IRRIGATION IN DRY YEARS
Provedor de dados: 31
Autores: Keplinger,   Keith O.; McCarl,   Bruce A.; Chowdhury,   Manzoor E.; Lacewell,   Ronald D.
A dry year irrigation suspension has been proposed as a way of reallocating water when aquifer levels are low for the Texas Edwards Aquifer. Under this program, farmers would be paid to suspend irrigation to allow more spring flow or nonagricultural pumping. When irrigation is suspended in the east, springflow response is markedly larger than when suspended in the western portions of the aquifer. Most acreage participates when a $90 per acre payment is offered before the cropping season. Considerably higher payments are needed and less water saved for a suspension program instituted during the cropping season.

Autores: Lopez,   Rigoberto A.
The objective of this article is to estimate historical economic surpluses for the subsectors involved in the U.S. sugar market.  Annual producer and consumer surpluses were computed based on a five-equation model and 1958-87 data.  In the last decade, the welfare position of cane- and beet-sugar producers has been roughly maintained, the domestic consumer surplus and the export quasi-rents to foreign countries have both declined, and quasi-rents of the corn-sweetener industry now surpass those that accrue to the cane industry and are about the same as those of the beet-sugar industry.  Some policy implications are discussed.

Recognition of the economic cost of weeds is important for a number of reasons which include the rationalization of weed control programmes and the direction of weeds research. Because of data deficiencies relating to extent and distribution, impact on production and the environment, and the spread potential of individual weed species, this area of weeds research has to date received little attention. In this paper, the concepts of economic surplus are utilized in a general social benefit framework to assess the economic importance of serrated tussock (Nassella trichotoma), the major...

FORWARD SHIPPING OPTIONS FOR GRAIN BY RAIL: A STRATEGIC RISK ANALYSIS; SUMMARY
Provedor de dados: 31
Autores: Priewe,   Steven R.; Wilson,   William W.
Grain hauling railroads began offering shipping alternatives in the late 1980s that have made transportation decisions more strategic. Shippers now confront alternatives ranging from nearby and unguaranteed ordering to various durations of forward and guaranteed shipment.  A dynamic stochastic simulation model was developed to analyze grain shipping and merchandising strategies that integrate these alternatives.

Motivation for Technology Adoption and Its Impact on Abandonment: A Case Study of U.S. Cotton Farmers
Provedor de dados: 31
Autores: Uematsu,   Hiroki; Mishra,   Ashok K.; Roberts,   Roland K.; Lambert,   Dayton M.; English,   Burton C.
We estimate a bivariate probit model with sample selection to identify factors affecting adoption and abandonment of precision farming technologies for cotton farmers, using the 2009 Southern Cotton Precision Farming Survey conducted in 12 Southern states in the United States.  Farmers for whom being at the forefront of agricultural technology is not an important reason for adoption are more likely to abandon precision farming technologies.  This study identified various factors associated with adoption and retention of precision farming technologies. Findings from this study offer significant information to policy‐makers for a better formulation of agri‐environmental programs that encourage farmers to adopt environmentally benign farming practices...

Agricultural Efficiency Gains and Trade Liberalization in Sudan
Provedor de dados: 31
Autores: Siddig,   Khalid H.A.; Babiker,   Babiker Idris.
The traditional agriculture in Sudan occupies 60% of the total cultivated land and employs 65% of the agricultural population. Nevertheless, it is characterized by its low crop productivity, which is mainly driven by low technical efficiency, while drought and civil conflicts threaten most of its areas countrywide.  Therefore, it has contributed only an average of 16% to the total agricultural GDP during the last decade. This paper addresses from an empirical point of view the sectoral and macroeconomic implications of agricultural efficiency improvement in Sudan and assesses the efficiency gains under the assumption of trade liberalization. Efficiency improvement experiments are implemented by augmenting the efficiency parameters of labor, capital, and...

FREEZE RISK AND ADOPTION OF TECHNOLOGY BY ORANGE PRODUCERS
Provedor de dados: 31
Autores: Schmitz,   Andrew; Rimal,   Arbindra.
Orange producers in many regions of the U.S. are affected by the recurrence of frost.  This study evaluated 147 California farmers' perceptions of frost risk relative to other business risks.  Freeze risk perception was negatively related, for example, to farm size.  Large farmers with diversified businesses had lower perceptions of freeze risk than small farmers.  Change in crop location and the adoption of anti-frost technology were two important responses to freeze risk.  California farmers shifted their location to frost-prone areas and adopted anti-frost technology.  Florida farmers, however, diversified to less frost-prone areas and adopted new planting technologies instead of anti-frost technologies. Key words: anti-frost technologies,...

THE ECONOMICS OF GRAIN PRODUCER CARTELS
Provedor de dados: 31
Autores: Gleckler,   James; Tweeten,   Luther G.
The objective of this study is to measure economic payoffs from a grain cartel. Two basic approaches to extract economic rents are considered: (i) Mandatory supply controls to restrict production and raise grain price, and (2) export price discrimination using export taxes or subsidies. The economic impacts of different producer cartel scenarios were estimated using a long-term, nine-region world trade simulation model incorporating the assumptions of neoclassical trade theory. The SWOPSIM program was used to write the model equations. Economic Research Service trade data for 1989 were used to initialize the model. Results reflect long-run changes from 1989conditions and are at 1989 general price levels. The model simultaneously estimated outcomes in...

Autores: Taruvinga,   Amon; Mushunje,   Abbyssinia.
Increased droughts in southern Africa have noticed some appreciation of the role that partial wetland cultivation can play to address household food security. This has also witnessed some indication of possible relaxation of wetland cultivation restrictive policies in Zimbabwe. However, the general perceptions of society towards wetland cultivation remain unclear and critically important for policy crafting before blanket recommendations are made. Using a Binary Logistic Regression Model seven predictor independent variables were regressed against a binary dependent variable of wetland cultivation status of households with the implicit goal of estimating socio-economic factors capable of influencing households` participation in wetland cultivation.

Pollution of the environment by metals and organic contaminants is an intractable global problem, with cleanup costs running into billions of dollars using current engineering technologies. The availability of alternative, cheap and effective technologies would significantly improve the prospects of cleaning-up metal contaminated sites. Phytoremediation has been proposed as an economical and ‘green’ method of exploiting plants to extract or degrade the contaminants in the soil. To date, the majority of phytoremediation efforts have been directed at leaping the biological, biochemical and agronomic hurdles to deliver a working technology, with scant attention to the economic outlook other than simple estimates of the cost advantages of phytoremediation over...

IMPACTS OF PRICE VARIABILITY ON MARKETING MARGINS AND PRODUCER VIABILITY IN THE TEXAS WHEAT INDUSTRY
Provedor de dados: 31
Autores: Brorsen,   B. Wade; Grant,   Warren R.; Richardson,   James W.; Schnake,   L.D.
The effects on marketing margins and Texas what producers of shifting from a period with stable prices to a period without stable prices were investigated using both econometric and simulation techniques.  Empirical evidence reveals wheat export firms are risk averse and that either futures markets were unable to absorb increased price risk or futures markets absorbed increased price risk at a cost of $0.054 per bushel.  Increased variability in prices and reduced farm program benefits substantially reduced the probability of Texas wheat producers receiving a reasonable return on equity and a reasonable rate of asset accumulation.

This paper analyses the demands from the society of Castilla y León (Spain) regarding its agricultural sector through the valuation of the relevance of its productive and non-productive functions. Additionally, it assesses the level of social satisfaction concerning the performance of these functions by irrigated agriculture in this region. For this purpose primary data colleted through a survey has been used. Results obtained show that the average citizen does not perceive a higher utility from irrigated agriculture compared with the whole agricultural sector. For these agricultural systems the social function is the element of multifunctionality considered most relevant regarding the perceived social welfare.

Will Higher Shipping Costs Drive the U.S. to Source More Localized Produce?
Provedor de dados: 31
Autores: Woods,   Timothy A.; Saghaian,   Sayed H.; Ona,   Lucia Y.
The recent wide fluctuations in diesel fuel costs and subsequent trucking costs has raised speculation within the produce industry of potential structural shifts in the location of production.  Recent increases in demand for local produce seem to further support speculation toward this end.  A component pricing model is used to actually examine the impact of fuel prices on farm gate and retail produce prices for strawberries, lettuce, and potatoes.  The study finds that distribution costs, while significantly increasing in absolute value, have surprisingly little contribution to changes in retail prices even in markets distant to the primary production regions.  These results suggest that factors other than lower distribution costs for local produce will...

PROFITABILITY ANALYSIS OF BEAN PRODUCTION IN HONDURAS
Provedor de dados: 31
Autores: Tshering,   Chhime.
In Honduras, dry beans are the second most important staple crop, next to maize, in terms of both production and consumption. During the past decade, agricultural scientists in Honduras, in collaboration with Bean/Cowpea CRSP scientists, have released numerous new varieties, developed improved bean-management practices, and actively worked with governmental agencies, NGOs, and farmer groups to ensure that these improved technologies are widely available to farmers. However, data on national bean production in Honduras fail to demonstrate that agricultural research has had an impact on bean production, yields, and area harvested. Given the situation, profitability analysis represents an alternative approach for assessing the farm-level impact of research....

Traditionally, the South African farmer has always been an entrepreneur, running his/her farming activities as a business to support lifestyle, provide a future for the children (as successors to the family farm or by providing education for a career) and to provide for comfortable retirement one day. However, a number of climatic- and economic environmental issues has resulted in severe constraints to farmers as entrepreneurs, creating a situation where farming are on the brink of collapse and maize farmers are struggling to survive. The production years 2005/6 and 2006/7 are critical.

A Bayesian Approach to Optimal Cross-Hedging of Cottonseed Products Using Soybean Complex Futures
Provedor de dados: 31
Autores: Rahman,   Shaikh Mahfuzur; Dorfman,   Jeffrey H.; Turner,   Steven C.
Cottonseed crushers face substantial risk in terms of input and output price variability and they are limited in their planning by the lack of a viable futures contract for cottonseed or cottonseed products. This study examines the feasibility of cross-hedging cottonseed products using the soybean complex futures. Different cross-hedging strategies are evaluated for eight time horizons relative to the expected profit and utility of the crusher. A Bayesian approach is employed to estimate both model parameters and optimal hedge ratios, allowing consistency with expected utility maximization in the presence of estimation risk. The results reveal that both whole cottonseed and cottonseed products can be successfully cross-hedged using soybean complex futures....

Changes in Yield Stability: Wheat and Maize in Developing Countries
Provedor de dados: 31
Autores: Gollin,   Douglas.
This study asks whether the diffusion of modern varieties has affected the yield stability of wheat and maize production in developing countries between 1960 and 2004. The data suggest strongly that, over the past forty-plus years, there has been a striking decline in the relative variability of grain yields in wheat and (to a lesser extent) maize. The declines are strongest when measured as the standard deviation of yield divided by the mean, but there have also been declines in other measures of variability, such as the percentage deviation from trend. Declines in yield variability do not appear to be driven by increases in intensification (e.g., irrigation), nor do they appear to extend to crops, such as oilseeds, in which there has been little...

This study examines several aspects of the Environmental Horticulture Industry (EHI) in the northeastern United States. First, the EHI is compared to other agricultural sectors in the region. The sector's growth is found to far outpace growth in traditionally important crops and commodities. The study then takes a closer look at the EHI in Pennsylvania, utilizing survey data and the IMPLAN input-output model to estimate the overall economic contributions of the industry to the state's economy. Results suggest that the EHI generates nearly $3.3 billion in value-added and more than 107,000 state jobs through direct, indirect, and induced effects. Finally, survey data are used to identify and discuss important issues that land grant universities throughout...

SOME ECONOMIC ASPECTS OF CURRENT PRODUCTION, MARKETING AND DISTRIBUTION POLICIES OF MAIZE IN KENYA AND A PROPOSED FRAMEWORK FOR GENERATING INFORMATION ON ITS DEMAND AND SUPPLY
Provedor de dados: 31
Autores: Chege,   Fred E.
Maize is one of the most important crops grown in Kenya.  It is important as a basic staple, a source of income to many Kenyans, a source of raw material for a budding manufacturing industry as well as a source of foreign exchange.  In fact, maize has been identified by the government as a major growth factor in agriculture.  The principal reason behind this rather special government ranking of the maize industry is that, whereas about 90 percent of the Kenyan population depends on maize as their basic staple food, the country was unable to produce sufficient maize to meet domestic requirements until the early 1970's.  Frequent shortages of maize have sometimes resulted in serious famines which, a part from causing a lot of suffering to many people, have...

EXPLAINING THE ADOPTION AND DISADOPTION OF SUSTAINABLE AGRICULTURE: THE CASE OF COVER CROPS IN NORTHERN HONDURAS
Provedor de dados: 31
Autores: Neill,   Sean P.; Lee,   David R.
Although technology adoption has been the subject of a great deal of economic research, that focused on the economics of adoption of low-input "sustainable" systems has been much more limited and recent. This paper attempts to explain the recent decline in the use of cover crops using in maize farming in the Department of Atlantida, Honduras. In the early 1970's, farmers in the region began rotating maize with the velvetbean (mucuna ssp.), a system learned from Guatemalan immigrants. Tohe mucuna-maize system decreased the labor required for maize farming even as it increased yields, prevented erosion, and conferred a variety of other agronomic benefits. By 1992, estimates show that the system had diffused among more than 60% of farmers in the Department....

The farm level economic impacts of the Farm Security and Rural Investment Act of 2002 (2002 Farm Bill) on representative crop and livestock operations are projected in this report. The analysis was conducted over the 2002-2009 planning horizon using FLIPSIM, AFPC’s whole farm simulation model. Data to simulate farming and ranching operations in the nation’s major production regions came from two sources: - Producer panel cooperation to develop economic information to describe and simulate representative crop, livestock, and dairy farms. - Projected prices, policy variables, and input inflation rates from the Food and Agricultural Policy Research Institute (FAPRI) August 2005 Baseline. The primary objective of the analysis is to determine the farms’...

The Agricultural and Food Policy Center (AFPC) at Texas A&amp;M University develops and maintains data to simulate 100 representative crop, dairy, and livestock operations in major production areas in 28 states. The chief purpose of this analysis is to project those farms’ economic viability by region and commodity for 2006 through 2011. The data necessary to simulate the economic activity of these operations is developed through ongoing cooperation with panels of agricultural producers in each of these states. The Food and Agricultural Policy Research Institute (FAPRI) provided projected prices, policy variables, and input inflation rates in their August 2006 Baseline. Under the August 2006 Baseline, 14 of the 65 crop farms are considered in good...

Tart Cherry Yield and Economic Response to Alternative Planting Densities
Provedor de dados: 31
Autores: Me-Nsope,   Nathalie Mongue.
The study investigates the economic response of tart cherry yields to planting density using an unbalanced longitudinal yield data from tart cherry orchards in Northwest Michigan. The relationship between tart cherry yield and tree age is specified as a linear spline function and planting density interacts with tree age. A random effect method, treating block as random, is used to estimate the spline function. Stochastic simulation was used to estimate the mean and variance of the product of two random variables (price and yield), and the coefficient of variation was used as a measure of how much risk is involved in corn/soybeans production relative to tart cherries production. Estimates of the variance provided the discount factor (10%) and with yields...

CASH MARKETING STYLES AND PERFORMANCE PERSISTENCE OF WHEAT PRODUCERS
Provedor de dados: 31
Autores: Cunningham,   Lewis T., III; Brorsen,   B. Wade; Anderson,   Kim B.
Years of research have been dedicated to determining the best time for producers to sell their commodities. Researchers have developed basis models, market efficiency tests, hedging/risk models, price forecasting models, and many other models in an attempt to help producers. There is a vast amount of material on how economists believe that a rational producer should act and react in the market place. However, there is little research on how producers actually sell commodities. This paper first measures the extent to which producers display an active or mechanical marketing style using individual farmer sales. Next, tests of performance persistence are conducted to determine if there is any advantage to an active marketing style. The results show that...

SOIL MANAGEMENT AND THE FARM TYPOLOGY: DO SMALL FAMILY FARMS MANAGE SOIL AND NUTRIENT RESOURCES DIFFERENTLY THAN LARGE FAMILY FARMS?
Provedor de dados: 31
Autores: Soule,   Meredith J.
There is increasing recognition that farmers face constraints on their farming decisions depending on the their resources, stage in life, and lifestyle choices.  These factors are captured in a new farm typology developed by the Economic Research Service.  The farm typology's definition of small and large farms is used to test the commonly stated hypothesis that small farmers practice better land husbandry than do large farmers.  The adoption of eleven different soil and nutrient management practices used by U.S. corn producers is analyzed with a bivariate logit model for each practice.  The farm typology is found to be significantly associated with two of the practices – rotation with legumes and conservation tillage.

The explicit evaluation of the post-harvest losses at different stages of marketing and their impact on farmers’ net price, marketing costs, margins and efficiency have been presented. It has been found that the existing methods tend to overstate the farmers’ net price and marketing margins of intermediaries. In fact, the margin of the retailers’ after taking into account the physical loss during retailing has been found to be negative (loss), which otherwise, was positive (profit) in the conventional estimation. Similarly, the producers’ net share and wholesalers’ margins also decrease substantially. It has been shown that marketing efficiency is inversely proportional to the marketing losses. The co-operative marketing has been found to be a more...

Production costs and economies of size for both conventional tillage and no-till wheat production were determined.  The reduction in the price of glyphosate after the patent expired improved the relative economics of no-till for continuous monoculture winter wheat.  Production costs differ across farm size and by production system.

A wealth of research papers, reports, and newsprint demonstrate the wide international interest in the ecological deterioration in the Aral Sea Basin in Central Asia (CA). The demise of the Aral Sea is a symptom that results from intensive agricultural activities aiming at maximizing agricultural production while neglecting environmental sustainability, as exemplified by the land use patterns also prevalent in the Republic of Uzbekistan, one of the five newly established states in CA. The environmental degradation is acute and continues, since various factors conducive to it have not been eradicated. This discussion paper deals with the potential role of forestry-based production systems and in their contribution to counterbalancing the ecological...

Storage, Trade, and Price Policy Under Production Instability: Maize In Kenya
Provedor de dados: 31
Autores: Pinckney,   Thomas C.
Instability in the production of a staple food causes severe hardship for many countries. For a country that is self-sufficient in its staple food in a normal production year, the large swings in price and consumption that result from an exclusive and uninhibited reliance on trade to stabilize prices are unacceptable. Most countries, therefore, intervene in their domestic cereal markets and move supplies from surpluses to deficit years through storage or by subsidizing international trade. The appropriate method of intervention and the most efficient way to achieve supply stability thus became topics of study. For the most part, economist have encouraged governments to rely more on trade than on stocks to make up deficits on years of production shortfalls....

The Comparative Cost and Profit Analysis of Organic and Conventional Farming
Provedor de dados: 31
Autores: Urfi,   Peter; Hoffmann,   Andras; Kormosne-Koch,   Krisztina.
The cost-profit relations of organic and conventional farming were examined on the basis of natural and financial data of a large agricultural - company in western Hungary and of economic models characterising private farms in eastern Hungary. The differences in cost structures reflect variable conditions relating to certain crops, but they can be well explained by the differences in the technologies used. According to the production data, in organic farming direct costs per hectare were lower in all of the four examined crops. Even cost per production unit and contribution were more favourable in three of the investigated crops. Regarding the calculation done by economy models, the costs per hectare relating to the two production methods were not...

Autores: Martinez,   Lourdes R.; Thornsbury,   Suzanne; Nagai,   Tomokazu.
This report presents global and domestic information regarding production, trade and market developments for pickled cucumbers. U.S. cucumber production and trade are commonly divided into two categories: fresh and pickling. Michigan is the largest producer of pickling cucumbers in the country, accounting for 18 percent of total U.S. production. Like many agri-food industries, this processed product sector has gone through numerous changes in the past decade which have influenced production and marketing trends, and assessing the influence of individual factors is difficult. However, using production and trade data it is possible to infer some possible drivers of trends and outcomes for the industry.   Year-round supply from other countries, quality...

COSTS AND RISKS OF CONFORMING TO EU TRACEABILITY REQUIREMENTS: THE CASE OF HARD RED SPRING WHEAT
Provedor de dados: 31
Autores: Wilson,   William W.; Henry,   Xavier; Dahl,   Bruce L.
Stochastic simulation was used to determine the marginal cost and optimal testing strategy (location and intensity) for an integrator conforming to proposed European Union traceability requirements for imported hard red spring wheat.  Cost, risks and premiums were determined for exports of non-genetically modified (non-GM) wheat from the U.S. to the EU.  Cost components include certified seed, certification and auditing, testing, traceability, quality loss, and a risk premium for the added risk of a dual traceability system over a single non-traceability system.  The optimal strategy is the one that maximizes the integrator's utility (minimizes disutility of integrator's additional costs).  Adventitious commingling is defined stochastically.  Results...

Since the inception of Pro-Fac Cooperative (PF) in 1960, the cooperative has undergone significant structural and organizational changes. The PF case presents a unique opportunity to examine the changes in the processed fruit and vegetable industry and the strategies adopted by a producer-owned cooperative to best represent member interests in the face of the industry structural changes over the past fifty years. PF is an agricultural cooperative that markets crops primarily grown by its member-growers, including fruits (cherries, apples, blueberries, and peaches), vegetables (snap beans, beets, peas, sweet corn, carrots, cabbage, squash, asparagus and potatoes), and popcorn.  Members are located principally in the states of New York, Delaware,...

Saskatchewan Wheat Pool
Provedor de dados: 31
Autores: Painter,   Marvin J.
In 1996, Saskatchewan Wheat Pool embarked on a strategy for growth and diversification by significantly expanding its asset base. This expansion brought with it many new costs, especially new fixed costs such as interest and depreciation. They failed to achieve the new revenues needed to support the higher fixed costs and consequently, found themselves in financial distress. In 2000, Mayo Schmidt was brought in as CEO to turn the company back to profitability. His strategy was to sell off all non-core assets and focus on the core businesses that built the company; grain handling and supplying farm inputs. 2004 would be a crucial year for Saskatchewan Wheat Pool.

Provedor de dados: 31
Autores: Meyer,   Ferdinand H.; Kirsten,   Johann F.; Poonyth,   Daneswar.
In this study, the structure of the South African wheat market is analysed using economic theory and econometric modelling techniques. The developed model is used to make baseline projections regarding the supply and use of wheat in South Africa and to analyse the impacts of various policy alternatives on the wheat sector for the period 2002 – 2008. Results indicate that after an initial decline in the area harvested in 2003, the area harvested will increase over time. Domestic consumption will gradually decrease over time, which will result in lower levels of imports and higher level of exports. Three policy scenarios are analysed, the elimination of the import tariff for wheat, a twelve percent depreciation in the exchange rate, and the convergence of...

Farm Animal Welfare, Consumer Willingness to Pay, and Trust: Results of a Cross-National Survey
Provedor de dados: 31
Autores: Nocella,   Giuseppe; Hubbard,   Lionel J.; Scarpa,   Riccardo.
Higher animal welfare standards increase costs along the supply chain of certified animal-friendly products (AFP). Since the market outcome of certified AFP depends on consumer confidence toward supply chain operators complying with these standards, the role of trust in consumer willingness-to-pay (WTP) for AFP is paramount. Results from a contingent valuation survey administered in five European Union countries show that WTP estimates were sensitive to robust measures of consumer trust for certified AFP. Deriving the WTP effect of a single food category on total food expenditure is difficult for survey respondents; hence, a budget approach was employed to facilitate this process.

An econometric model of cotton acreage response was estimated for four distinct production regions in the United States. This work builds on previous work in the area of supply response under government farm programs and provides up-to-date regionalized estimates of own-price elasticity of cotton acreage supply. The own-price variable used in this study is a weighted combination of expected market price and government policy variables. Results indicate regional similarity in response to own price but differences with respect to the prices of alternative enterprises. Differences in regional response to paid diversion are also indicated.

AN ANALYSIS OF RICE SUPPLY AND DEMAND IN THE IVORY COAST
Provedor de dados: 31
Autores: Coulibaly,   Dramane.
Despite the importance of rice in Ivorians's diet, and thus in the economy of the Ivory Coast, self-sufficiency in rice production, until recently, has received little attention from economists and statisticians.  Agronomists, sociologists and anthropologists have examined in some detail the cultural practices, soils, land barriers, tools and basic techniques used by the Ivorian farmers.  But they have failed to produce much needed basic information related to crop acreage, yields, prices and other areas which are most relevant for policy formulation.  This paper analyzes the rice demand and supply in the Ivory Coast, and attempts to estimate both price and income elasticities of demand, and price elasticity of supply.

Price competitiveness and variability in Egyptian cotton: effects of sectoral and economywide policies
Provedor de dados: 31
Autores: Bautista,   Romeo M.; Gehlhar,   Clemen G.
This paper examines the role of price incentives in the observed decline in cotton production during the 1980s and in the apparent improvement in recent years. The following determinants (in an accounting sense) of the changes in the relative producer price of cotton during 1980-92 are quantified: (1) changes in the foreign price; (2) changes in the real exchange rate; and (3) changes in nominal protection and the marketing margin. An estimated model of the real exchange rate for Egypt is used to provide a further decomposition of the changes in the relative cotton price that isolates the effect of policy-related factors. The comparative effects of sectoral and economywide policies are analyzed based on three alternative policy regimes in terms of the...

Provedor de dados: 31
Autores: Orr,   Leanne M.; McDougall,   Sandra; Mullen,   John D.
Research into IPM technologies has been conducted by NSW DPI for over 20 years. Evaluating the returns from investment in specific research and development projects is an important component of the NSW DPI science and research program. An economic evaluation has been conducted of IPM in managing invertebrate pests in lettuce in NSW. We found that there has been widespread adoption of IPM practices amongst NSW lettuce growers leading to a flow of economic benefits to the lettuce industry and the community. Important environmental and human health benefits were also identified. A benefit-cost ratio of 2 was calculated for the return to NSW DPI investment in lettuce IPM research which while satisfactory, is lower than returns calculated for other agricultural...

LOGISTICAL COSTS AND RISKS OF MARKETING GENETICALLY MODIFIED WHEAT
Provedor de dados: 31
Autores: Schlecht,   Shannon M.; Wilson,   William W.; Dahl,   Bruce L.
Genetically modified (GM) grains have increased in importance.  Moving biotech grains from producers to processors is a challenge for the grain handling system that could involve increased segregations.  The objective of this research is to determine how testing strategies affect the logistical costs of a grain pipeline when GM wheat is present.  A logistical model was developed and simulated to analyze impacts of uncertainty in demand, receipts, test accuracy, rail deliveries, and transit time.  Sensitivities were conducted on certain variables to determine their effects on logistical costs.  Analysis revealed that logistical costs are impacted by the number of quality categories and uncertainties in the system.  Adding GM grains increased costs due to...

Autores: Salin,   Victoria; Lard,   Curtis F.; Hall,   Charles R.
This research estimates the annual economic impact of the fire ant on key urban sectors in Texas.  A study was conducted in 1998-1999 in the 5 metroplexes of Austin, Dallas, Fort Worth, San Antonio and Houston to estimate the costs of controlling and managing fire ants (Lard, et al). This study found that the annual expenditure for fire ant control and management by selected sectors in these metroplexes totaled more than  $581 million. The total annual expense by sector amounted to $526 million for households, $29 million for golf courses, $25 million for schools, and $0.6 million for cities.  These annual cost figures do not include all urban costs or costs borne by electrical utility companies, communication firms and cable companies. These results can...

Autores: Hoque,   Ziaul; Farquharson,   Robert J.; Taylor,   Ian; Walker,   Steve; Osten,   Vikki; Jones,   Randall E.
Economic losses and costs associated with weeds in dryland cotton production are important, both for growers and for industry bodies when making decisions about research priorities and research and development funding. A survey was conducted to provide information on weed types, control strategies and estimated costs to growers. We used information from the survey to estimate conventional financial losses due to weeds, and as a basis for evaluating aggregate economic (society) impacts. An economic surplus model was used to estimate the aggregate societal impact of weeds for three production regions in north-eastern Australia. The annual economic costs associated with weeds were estimated to be $41 million, and the on-farm financial costs were $25 million....

Revisiting the "Cotton Problem:" A Comparative Analysis of Cotton Reforms in Sub-Saharan Africa
Provedor de dados: 31
Autores: Delpeuch,   Claire; Vandeplas,   Anneleen; Swinnen,   Johan F.M.
The cotton sector has been amongst the most regulated in Africa, and still is to a large extent in West and Central Africa (WCA), despite repeated reform recommendations by international donors. On the other hand, orthodox reforms in East and Southern Africa (ESA) have not always yielded the expected results. This paper uses a stylized contracting model to investigate the link between market structure and equity and efficiency in sub-Saharan cotton sectors and analyze the potential consequences of orthodox reforms in WCA. We argue that the level of the world price and of government intervention, the degree of post-reform competition, as well as the degree of parastatal inefficiency, all contribute to making reforms less attractive (but not less pressing)...

Harvest-Time Protein Shocks and Price Adjustment in U.S. Wheat Markets
Provedor de dados: 31
Autores: Goodwin,   Barry K.; Smith,   Vincent H.
Dynamic relationships among three classes of wheat are investigated using threshold VAR models that incorporate the effects of protein availability. Changes in the stock of protein are found to generate significant responses in the prices of hard red spring wheat and hard red winter wheat, but not soft red wheat. The responses to identical changes in protein stocks are larger when the magnitudes of deviations of protein stocks from normal levels are large. Shocks to the prices of individual classes of wheat result in complex responses in the prices of the other wheat classes. Notably, however, a shock to the price of hard red winter wheat appears to result in little or no response in the price of hard spring wheat, though importantly, the opposite is not...

ECONOMETRIC ESTIMATION OF TART CHERRY SUPPLY RESPONSE TO LOSS OF PESTICIDE ALTERNATIVES
Provedor de dados: 31
Autores: Rozanski,   Susan G.
Many agricultural producers are faced with the prospect of fewer chemical alternatives to mitigate damage from pests such as disease, weeds, insects, and rodents. Decreased pesticide availability can arise from health and environmental standards stipulated in federal and state regulations. Pesticide alternatives can also be lost due to natural pest resistance and economic considerations. The loss of pesticides due to economic considerations is especially troublesome to specialty crop producers such as fruit, fresh vegetable, and ornamental growers. Although these producers may use pesticides more intensively per acre than the major crop producers, the total acreage devoted to specialty crops is often not enough to warrant the pesticide registration costs...

Assessing Economic and Environmental Impacts of Ethanol Production on Fertilizer Use in Corn Production
Provedor de dados: 31
Autores: Nehring,   Richard F.; Vialou,   Alexandre; Erickson,   Kenneth W.; Sandretto,   Carmen L.
The share of corn used in ethanol production has been growing rapidly. USDA predicts that more than 30 percent of the corn crop will be used for ethanol production in 2009/2010. Expanded corn acreage contributes to the application of more fertilizer and is likely to introduce a larger volume of nutrients into the environment. This study found that an increase in ethanol production is consistent with a significant increase in quality-adjusted fertilizer use in selected corn states.

Aggregate and Farm-level Productivity Growth in Tobacco: Before and After the Quota Buyout
Provedor de dados: 31
Autores: Kirwan,   Barrett E.; White,   T. Kirk; Uchida,   Shinsuke.
We examine the distortionary effects of agricultural policy on farm productivity by examining the response of U.S. tobacco farmers' productivity to the quota buyout of 2004. We isolate the impact of distortionary policy, i.e., the tobacco quota, by decomposing aggregate productivity growth into the contribution of farm-level productivity growth and the contribution of reallocation of resources among tobacco growers. Reallocation of resources includes entry into and exit from tobacco farming, as well as growth or decline of the resources allocated to existing tobacco farms. We find that aggregate productivity of Kentucky tobacco farms grew 37% between 2002 and 2007.  Reallocation of resources among continuing tobacco farms contributed 22 percentage points...

Adjustment of Wheat Production to Market Reform in Egypt
Provedor de dados: 31
Autores: Kherallah,   Mylene; Minot,   Nicholas; Gruhn,   Peter.
In response to slow growth in the agricultural sector and as part of a general shift towards a more market-oriented economy, the Government of Egypt started liberalizing the agricultural sector in 1987. Controls over wheat production and marketing were eliminated and wheat producer prices were brought closer to international levels. As a result, there has been remarkable increases in wheat crop area and yields, causing wheat production to triple from 1986 to 1998. This study analyzes the results of a survey of 800 Egyptian wheat farmers in order to address three issues that are of interest to agricultural reform policy in Egypt. First, what are the patterns in wheat production and marketing that have emerged following the economic reforms? Second, why is...

Pricing and Marketing Practices for North Dakota Durum and HRS Wheat: 1991 Crop Year
Provedor de dados: 31
Autores: Scherping,   Daniel J.; Wilson,   William W.
Buyers of grain use premiums and discounts to convey to suppliers the value of quality characteristics. Premiums and discounts are determined by supply and demand for those quality characteristics. This report, the eighth in a series, contains the results of a 1991 survey of pricing and marketing practices used by North Dakota country elevators for durum and hard red spring (HRS) wheat. Results for HRS wheat show that the protein level increased to the highs of 1988 and 1989 and that the premium for 16 percent protein and the discount for 12 percent protein decreased from the previous year. Discounts continued the downward trend of recent years.

Local Seed Markets and the Determinants of Crop Variety Diversity in Marginal Environments: The Case of Millet in Semi-Arid India
Provedor de dados: 31
Autores: Nagarajan,   Latha; Smale,   Melinda; Glewwe,   Paul.
The purpose of the research paper is to characterize biological diversity related to millets in the semi-arid regions of India at various spatial scales of analysis (e.g., farm household versus community levels) and place that evidence in a broader seed systems (includes both formal and informal) context.  An important finding of this research is that producer access to millet genetic resources is affected by the extent to which seed is traded via formal markets or through other social institutions, along with farm and household characteristics. Findings also underscore the need for an enhanced theoretical understanding of local seed markets in analyzing crop variety choices and the diversity of materials grown in less favored environments.

Estimating Non-linear Weather Impacts on Corn Yield—A Bayesian Approach
Provedor de dados: 31
Autores: Yu,   Tian; Babcock,   Bruce A.
We estimate impacts of rainfall and temperature on corn yields by fitting a linear spline model with endogenous thresholds. Using Gibbs sampling and the Metropolis - Hastings algorithm, we simultaneously estimate the thresholds and other model parameters. A hierarchical structure is applied to capture county-specific factors determining corn yields. Results indicate that impacts of both rainfall and temperature are nonlinear and asymmetric in most states. Yield is concave in both weather variables. Corn yield decreases significantly when temperature increases beyond a certain threshold, and when the amount of rainfall decreases below a certain threshold. Flooding is another source of yield loss in some states. A moderate amount of heat is beneficial to...

Autores: Dixon,   Bruce L.; Garcia,   Philip; Adams,   Richard M.; Mjelde,   James W.
Duality methods utilizing a profit function framework are employed to estimate the output elasticity of ambient ozone levels on cash grain farms in Illinois.  While duality methods have been recommended as a cure to many of the statistical problems of direct estimation of production functions, multicollinearity may still be a problem.  A method for utilizing stochastic information on parameters of a seemingly unrelated system of equations, which is implied by profit function estimation, is developed and applied to measuring the impact of ozone.  Such an approach may be necessary in measuring other environmental effects because of a lack of regressor variability.

Farming systems research for wet-season non-rice upland crops in Cambodia is being conducted with the overall aim of poverty reduction and food security for farmers in the Provinces of Battambang and Kampong Cham. Some of these cash crops exhibit low and variable incomes, especially when grown in the early wet season. Cambodian farmers may borrow money to buy crop inputs and often sell their produce to companies and traders from neighbouring countries, hence they are price takers. Some new crop technologies are evaluated which relate to soil and crop fertility management interacting with climatic factors. The DSSAT crop simulation model is used to predict outcomes from alternative management strategies. Bio-economic analyses are conducted to assess the...

Cassava production has grown rapidly in Zambia since the early 1990’s. Available evidence suggests that volumes of traded cassava have been increasing roughly twice as fast as production.  Yet this cassava production boom could stall unless commercial markets for it develop. To help accelerate commercial development of cassava and cassava-based products at the national level, Zambia’s Agricultural Consultative Forum (ACF) initiated an Acceleration of Cassava Utilization (ACU) Task Force, beginning in August 2005. At a regional level, efforts such as the Cassava Transformation in Southern Africa (CATISA) project aim to complement national efforts and help facilitate regional spillovers, so that new products, new technologies or new lessons can help to...

ECONOMIC ANALYSIS OF ENVIRONMENTAL BENEFITS OF INTEGRATED PEST MANAGEMENT
Provedor de dados: 31
Autores: Mullen,   Jeffrey D.; Norton,   George W.; Reaves,   Dixie Watts.
Public support for integrated pest management (IPM) is derived in part from concerns over food safety and the environment, yet few studies have assessed the economic value of health and environmental benefits of IPM.  An approach is suggested for such an assessment and applied to the Virginia peanut IPM program.  Effects of IPM on environmental risks posed by pesticides are assessed and society's willingness to pay to reduce those risks is estimated.  The annual environmental benefits of the peanut IPM program are estimated at $844,000.  The estimates of pesticide risks and willingness to pay can be applied elsewhere in economic assessments of IPM.

IS INCREASED INSTABILITY IN CEREAL PRODUCTION IN ETHIOPIA CAUSED BY POLICY CHANGES?
Provedor de dados: 31
Autores: Alemu,   Zerihun Gudeta; Oosthuizen,   Klopper; van Schalkwyk,   Herman D.
In Ethiopia, growth in cereal production is accompanied by a more than proportionate increase in the standard deviation of production. This study applies descriptive and variance decomposition procedures to determine the sources of increased instability in cereal production in order to show whether they are caused by policy changes. It was found that production instability was caused more by increased yield instability. Considering the fact that use of high-powered inputs is limited to a small number of farmers, production is at subsistence level and that farmers' responsiveness to policy changes is constrained by infrastructural and institutional constraints and by the existing land policy, instability in yield is predominantly attributed to weather...

Danish farmers have been far less interested in agri-environmental subsidy schemes than anticipated. We use choice experiments to estimate 486 Danish farmers’ preferences for a number of policy relevant scheme-characteristics. Subsidy schemes for pesticide free buffer zones along hedgerows are used as a case and analysed using a random parameter logit framework. By quantifying farmers’ preferences in monetary values, we are able to assess the relative importance of individual scheme-characteristics. Farmer’s assessments of the administrative burden are captured by estimating how they value free-of-charge assistance for the application procedure. To our knowledge, this measure of administrative burden has not been tested before. Our results indicate that...

The impact of the CAP reforms on the efficiency of the COP sector in Spain
Provedor de dados: 31
Autores: Lambarraa,   Fatima; Stefanou,   Spiro E.; Serra,   Teresa; Gil,   Jose Maria.
The arable crop sector (COP) occupies a prominent position within the European Union’s agricultural sector. Within Spain, the COP sector accounts for almost a third of total Agricultural Guidance and Guarantee Fund expenses, and a half of the utilised agricultural area. The COP sector is not only relevant because of its physical and economic magnitude, but also because of the political attention it receives. The Common Agricultural Policy reforms that occurred during the 1990s paid special attention to this sector. This paper aims at determining the impacts of Agenda 2000 on a sample of Spanish COP farmers’ production decisions by using an output-oriented stochastic distance function. The distance function allows assessing the reform-motivated changes on...

Canola has become an important crop in the last decade in the U.S. Production of canola is risky and competes with other crops which have a range of risk reduction mechanisms. Alternative contracting strategies were evaluated by comparing returns to labor and management for growers and gross margins for processors. Alternative contracting strategies included no contract, fixed price with and without act of god provisions, and an oil premium contract. Grower returns and processor gross margins were simulated and resulting distributions were evaluated using stochastic efficiency with respect to a function.

Does Crop Insurance Affect Crop Yields?
Provedor de dados: 31
Autores: Roberts,   Michael J.; O'Donoghue,   Erik J.; Key,   Nigel D.
We use administrative data from the Federal crop insurance program to examine how yield distributions change as farmers cycle into and out of the program.  We are able to do this by linking many years of crop insurance data by individual farm conditioning observed yields on the particular county and year in which they are observed. Armed with millions of observations, we examine many states and five major crops: corn, soybeans, wheat, rice and cotton.  We find little evidence that yield distributions are affected by insurance.  An exception is rice in Arkansas, where insurance shifts the distribution markedly downward.

ECONOMETRIC PRODUCTION MODELS WITH ENDOGENOUS INPUT TIMING: AN APPLICATION TO ECUADORIAN POTATO PRODUCTION
Provedor de dados: 31
Autores: Antle,   John M.; Capalbo,   Susan Marie; Crissman,   Charles C.
In this article, a model was developed in which the quantity and timing of input and harvest decisions are endogenous.  The endogenous timing model allows all of the information about input and harvest behavior to be utilized, and it provides a basis for linking econometric production analysis to the time-specific analyses in other scientific disciplines used to assess the environmental or human health impacts of agricultural production practices. The case study of fungicide use on Ecuadorian potatoes was conducted with a unique data set containing detailed information on both quantity and timing of input use.  The results showed that both quantity and timing of chemical use were responsive to economic variables.

We focused on the Socio-Economic Evaluation of Farmer Field School Training on Integrated Pest Management in the humid forest region of Cameroon. The main objective was to assess the impact of training on integrated pest management (IPM) on cocoa farmer field school graduates. The results indicate that shade management, phytosanitary harvest, pruning, improved spraying practices and grafting of improved materials were adopted at the rate of 94, 93, 90, 66 and 35 % respectively, with the overall rate of adoption being 76 %. There was a 47 % reduction in the frequency of spraying fungicides and a 17 % reduction in the number of sprayers applied per treatment following the implementation of the training. Labour inputs increased significantly for pruning,...

CROP BASIS PATTERNS IN THE PRESENCE OF SPATIAL COMPETITION AND GOVERNMENT INTERVENTION
Provedor de dados: 31
Autores: Parcell,   Joseph L.
This study analyzes the effect of the Loan Deficiency Payment (LDP) program, established under the Federal Agriculture Improvement Reform (FAIR) act of 1996, on corn and soybean basis pattern patterns in Missouri.  Additionally, spatial competition is incorporated into the basis models.  Using weekly corn and soybean basis pattern data from 1993 through 2001 for multiple locations in Missouri, and incorporating a variable for when the LDP is in effect, empirical models examining factors affecting corn and soybean basis pattern patterns are estimated.   Results indicate that the presence of the LDP program has a significant economic impact on soybean basis.  Furthermore, spatial competition strengthens corn basis.

HIV/AIDS and Agrarian Livelihoods in Zambia: A Test of the New Variant Famine Hypothesis
Provedor de dados: 31
Autores: Mason,   Nicole M.; Chapoto,   Antony; Jayne,   Thomas S.; Myers,   Robert J.
Since the southern African food crisis of 2001/02, the ‘new-variant famine’ (NVF) hypothesis first proposed by de Waal and Whiteside (2003) has become an important part of the conventional wisdom surrounding the relationship between HIV/AIDS and food crises in the region. The NVF hypothesis suggests that HIV/AIDS is eroding agrarian livelihoods and exacerbating the effects of drought and other shocks on agrarian communities. These concepts have begun to shape the HIV/AIDS mitigation and food security policies and programs of governments and development agencies. To date, however, there is a dearth of empirical evidence to support the NVF hypothesis, and there have been no studies specifically designed to tests its predictions.

Provedor de dados: 31
Autores: Torre Ugarte,   Daniel de la; Sanford,   Scott; Skinner,   Robert A.; Westcott,   Paul C.; Lin,   William W.
The 1996 Farm Act gives farmers almost complete planting flexibility, allowing producers to respond to price changes to a greater extent than they had under previous legislation. This study measures supply responsiveness for major field crops to changes in their own prices and in prices for competing crops and indicates significant increases in responsiveness. Relative to 1986-90, the percentage increases in the responsiveness of U.S. plantings of major field crops to a 1-percent change in their own prices are wheat (1.2 percent), corn (41.6 percent), soybeans (13.5 percent), and cotton (7.9 percent). In percentage terms, the increases in the responsiveness generally become greater with respect to competing crops' price changes. The 1996 legislation has...

AN ANALYSIS OF THE FEASIBILITY OF IRRIGATION DISTRICT TRANSFER IN HONDURAS
Provedor de dados: 31
Autores: Hearne,   Robert R.; Martinez A.,   Carlos.
User participation in the management of irrigation systems has been touted as a means to establish incentives for proper operation and management, decrease distortionary governmental subsidies, and increase water-use efficiency.   The Government of Honduras has been in a process of rehabilitating and transferring management responsibility of the Flores irrigation districts to farmers.  This paper presents a review of the transfer process, an analysis of  farmers? capacity to accept financial responsibility for the systems, and an analysis of farmers? preferences towards the privatization process.  The research intends to support the ongoing transfer process by identifying constraints and proposing improved strategies.

BIOFUELS AND LEAKAGES IN THE FUEL MARKET
Provedor de dados: 31
Autores: Drabik,   Dusan; de Gorter,   Harry.
Leakage in the fuel market differs, depending on whether ethanol production is determined by a tax credit or consumption mandate. Two components of market leakage are distinguished: domestic and international. Leakage with both a tax credit and a consumption mandate depends on market elasticities and consumption/production shares, with the former having a bigger impact. Leakage is also more sensitive to changes in market supply and demand elasticities in the country not introducing biofuels. Although positive with a tax credit, market leakage can be negative with a consumption mandate, meaning that one gallon of ethanol can replace more than a gallon of gasoline. We also show that being a small country biofuels producer does not necessarily mean that...

Provedor de dados: 31
Autores: Lee,   Donna J.; Kim,   C.S.; Schaible,   Glenn D.
Soybean production ranks among the largest agricultural cash crops in the U.S., second only to corn. U.S. soybean production topped 3 billion bushels in 2005 with sales of $17 billion. Approximately 58% of U.S. soybeans are grown in Iowa, Illinois, Minnesota, Indiana, and Nebraska. A small percentage of the U.S. soybean crop, 2%, goes to human consumption in the form of whole beans, soybean oil, and soybean meal products. A third of the crop, 1 billion bushels per year is exported annually to China, EU, Mexico, Japan, and Taiwan, and other countries. Most of the crop, 2 billion bushels, goes to the U.S. livestock industry to feed poultry, hogs, and cattle. Variations in the supply of soybeans thus directly impact livestock production.

ECONOMICS OF PRODUCING FOR AN IDENTITY-PRESERVED (IP) GRAIN MARKET
Provedor de dados: 31
Autores: Gustafson,   Cole R.
Demand for identity-preserved (IP) crops produced by Northern Plains farmers is increasing.  Buyers are willing to pay a premium for grains that can be guaranteed to possess a unique characteristic.  Several general crop management practices apply to crops raised for IP.  These include greater investment in segregated storage facilities, more meticulous production, isolation, added cleaning/sorting, documentation, greater testing, additional marketing, and risks of liability.  To illustrate, the economics of producing certified seed for sale to other farmers is used as an example of IP grain production.  Many of the concepts and specific practices of certified seed production are applicable to most IP crops raised.

This study compares liquidity costs of electronic and open-outcry wheat futures contracts traded side-by-side on the Kansas City Board of Trade. Liquidity costs are considerably lower in the electronic market. Liquidity costs in the electronic market are still considerably lower after eliminating the bias created by splitting orders in the electronic market. Price volatility and transaction size are positively related to liquidity costs, while a negative relation is found between daily volume and liquidity costs. Price clustering at whole cent prices occurs in the open-outcry market which helps explain its higher liquidity costs. Daily volumes were distinctively higher during the Goldman-Sachs roll, but not enough to explain the higher liquidity costs in...

The Economic Feasibility of Sugarbeet Biofuel Production in Central North Dakota
Provedor de dados: 31
Autores: Maung,   Thein A.; Gustafson,   Cole R.
This study examines the financial feasibility of producing ethanol biofuel from sugar beets in central North Dakota. Under the Energy Independence and Security Act (EISA) of 2007, biofuel from sugar beets uniquely qualifies as an “advanced biofuel”. EISA mandates production of 15 billion gallons of advanced biofuels annually by 2022. A stochastic simulation financial model was calibrated with irrigated sugar beet data from central North Dakota to determine economic feasibility and risks of production for a 10MGY (million gallon per year) and 20MGY ethanol plant. Study results indicate that feedstock costs, which include sugar beets and beet molasses, account for more than 70% of total production expenses. The estimated breakeven ethanol price for the 20MGY...

Willingness to pay models have shown the theoretical relationships between the contingent valuation, cost of illness and the avertive behaviour approaches.  In this paper, field survey data are used to compare the relationships between these three approaches and to demonstrate that contingent valuation bids exceed the sum of cost of illness and the avertive behaviour approach estimates. The estimates provide a validity check for CV bids and further support the claim that contingent valuation studies are theoretically consistent.

Analytical models were developed in this paper to evaluate cost/risk tradeoffs of three alternative procurement strategies in the case of hard red spring (HRS) wheat. Results indicate a naive strategy has the lowest expected cost, but a high probability of not conforming to end-use requirements. Two alternative specifications for the constant share strategy result in higher probabilities of meeting requirements, but at higher costs. The opportunistic strategy results in a higher probability of meeting requirements than either of the other two alternative strategies at a comparable cost.

On farm conservation of crop diversity entails policy challenges, especially when the diversity of crops maintained on farms has both inter-specific (among crops) and infra-specific (within a crop) components. Survey data is used to compare the determinants of inter- and infra-specific diversity on household farms in the highlands of northern Ethiopia.  Physical features of the farm, and household characteristics such as livestock assets and the proportion of adults that are men, have large and significant effects on both the diversity among and within cereal crops grown, varying among crops. Demographic aspects such as age of household head and adult education levels affect only infra-specific diversity of cereals. Though there are no apparent trade-offs...

Pesticides Residues and Trade: the Apple of Discord?

Autores: Drogue,   Sophie; DeMaria,   Federica.
The impact of food safety standards on international trade has already been addressed. Generally, economists try to assess trade losses borne by exporters when importing countries impose stricter regulations. In this paper we assess the impact of the Maximum Residue Levels (MRL) of pesticides on the trade of apples and pears. Rather than focusing on a particular pesticide we take into account the entire list of substances set out by the various regulations with the aim is to understand how the similarity (or dissimilarity) of these can affect trade. Most studies assess the impact of sanitary standard regulations introducing directly in the analysis the MLR put in force in the importing country. We assume that what can be crucial is the difference in the...

During the past decade the Indian chickpea industry underwent a dramatic structural shift following the implementation of market-oriented policies by the Government of India.  This paper examines consumer attitudes to quality characteristics of chickpea in India.  A linear hedonic price model is estimated using auction price and quality data of chickpea samples obtained from major markets in India.  Empirical results indicate that specific physical quality characteristics and purity standards are important factors influencing the price of chickpea in India.  Thus, there may be an incentive for domestic producers and sellers of chickpea – and exporting countries – to improve the quality of their product, if improvements in specific physical characteristics...

During the last twenty years, the incidence of abnormal weather variation has increased, mainly due to El Nino. In Malaysia, the El Nino induced weather change has resulted in prolonged dry seasons, which have led to severe drought and increased temperatures. This has been further compounded by the formation of haze due to the large scale burning of forest and plantations for land preparation. These phenomena brought serious implications for farm productivity and land use patterns. This report describes, analyzes and quantifies the impact of El Nino induced climate variability on the agricultural sector and the rural economy. It also proposes measures to mitigate the damage and to stabilize agricultural production for the welfare of the rural population at...

Agricultural multifunctionality is the recognition of the joint exercise of economic, environmental and social functions by this sector. In order to make this concept operative for the design of public policies, it is necessary to estimate the social demand for such functions. The main objective of this article is to present an empirical application in this line. For this purpose we have taken the agricultural system of mountain olive groves in Andalusia (Southern Spain) at risk of abandonment after the decoupling of the EU subsidies as a case study. The economic valuation technique used is the Choice Experiment. According to the results, there is a different contribution of each attribute to the improvement of the Society level of utility.

This report evaluates the U.S. and world wheat markets for the 2004-2013 period using the Global Wheat Policy Simulation Model.  This analysis is based on a series of assumptions about general economic conditions, agricultural policies, weather conditions, and technological change.   Both the U.S. and world wheat economies are predicted to improve for the next nine years.  World demand for both common and durum wheat are expected to grow faster than world production, resulting in gradual increases in prices of the wheat varieties.  However, the higher price levels experienced in 2002 and 2003 due to weather conditions will not be maintained in the short term.  World trade volumes of both classes of wheat are expected to expand, but trade volume of durum...

Third Country Effects of Price Discrimination: The Case of the Canadian Wheat Board
Provedor de dados: 31
Autores: Rude,   James; Brewin,   Derek G.; White,   Martin.
This study considers whether the major concern with the behaviour of exporting state trading enterprises (STEs) should be the practice of price discrimination. Using a differentiated products world wheat model, the impacts of Canadian price discrimination on the welfare of competing exporters are considered. The results show that competing exporters could be better or worse off as result of price discrimination, but the impacts were small. Over a range of possible elasticities US producers were generally better off if North American arbitrage is assumed. Other wheat exporting regions could see their producer’s welfare change between 2 and -0.5%. Given these small impacts, the study suggests that explicit disciplines on discriminatory pricing exporting STEs...

The Long-Run Impact of Energy Prices on World Agricultural Markets: The Role of Macro-Economic Linkages
Provedor de dados: 31
Autores: Chantret,   Francois; Gohin,   Alexandre.
The world prices of food and energy products have followed similar large swings in recent years.  We investigate the long run relationship between these prices using a world Computable General Equilibrium model with detailed representations of food and energy markets.  Particular attention is paid to specify macro-economic linkages which have often been overlooked in recent analysis and debate.  We find that the omission of these macro-economic linkages has a substantial bearing on this relationship.  A positive relationship due to the cost push effect has been identified in most analysis, but we find that the introduction of the real income effect may indeed imply a negative relationship between world food and energy prices.  Accordingly, it is crucial to...

Foodgrain Supply, Distribution, and Consumption Policies within a Duel Pricing Mechanism: a Case Study of Bangladesh
Provedor de dados: 31
Autores: Ahmed,   Raisuddin.
Conflict between the short run welfare of poor consumers and agricultural production incentives creates some of the most difficult policy issues facing developing countries. Resulting policy option constraints are particularly severe in very low income countries. The conflict may on the one hand impede the growth in al production essential to improve long term welfare of low income consumers, and on the other hand restrain policies to increase consumption, which in the long run is essential to the success of the measures taken to increase production. The widely observed phenomenon of urban bias in food price policy is itself a product of the nature of low income societies and of this complex conflict.  This research by Raisuddin Ahmed delineates and...

The lower Krishna Basin trajectory: relationships between basin development and downstream environmental degradation
Provedor de dados: 31
Autores: Venot,   Jean-Philippe; Sharma,   Bharat R.; Rao,   Kamineni V.G.K.
Basin water development and rural dynamics in the Krishna Basin have led to a degradation of downstream ecosystems manifesting itself by salinizing soil and groundwater, increasing pollution, disappearing mangroves and desiccating wetlands. Reversing this evolution requires the formal recognition of the environment as a water user in its own right and the implementation of an environmental water provision. This provision should be based on a two-tier allocation system with assured discharges in the irrigation canals of the delta and to the ocean. This will lead to further commitment of water resources but this is needed to reconcile the social, economic and environmental objectives of a sustainable development. Other measures facilitating integrated...

Autores: Beltran,   Jesusa C.; Pannell,   David J.; Doole,   Graeme J.; White,   Benedict.
This paper describes a complex, dynamic simulation model that has been developed for the analysis of integrated weed management programmes for the control of annual barnyardgrass (Echinochloa crus-galli) in rice farming systems in the Philippines. Users of the model may simulate any feasible combination of 49 weed treatments options across wet and dry cropping seasons over 5, 10, 15, and 20 year periods, subject to a predetermined sequence of planting methods. The main outputs of the model include weed seed and plant densities and seasonal and annualised profit over the simulated planning horizon. Model output emphasises the substantial economic benefits associated with effective long-term weed management strategies. In addition, the most-profitable weed...

ON THE DEMAND FOR A STATE-CONTINGENT, COST-SAVING SEED TRAIT
Provedor de dados: 31
Autores: Hennessy,   David A.; Saak,   Alexander E.
Biotechnology has enriched the strategy set available to crop managers. Suppose a manager faces a decision between applying a pre-emergence pesticide or applying nothing at all. The advent of pesticide tolerance traits in plants admits the possibility of a state-contingent post-emergence application of pesticide. The innovation adds value in large part because it provides the manager with the option to wait for more information. For heterogeneous acre types, the determinants of trait royalties and of crop management strategies in equilibrium are studied. Pest resistance traits have different implications for crop management. Whereas a tolerance trait likely complements information technologies, the addition of a resistance trait may substitute for them.

Autores: Djuric,   Ivan; Goetz,   Linde; Glauben,   Thomas.
This paper analyzes how the market interventions of the Serbian government during the food crisis 2007/2008, inter alia a de facto export ban, have affected domestic wheat markets. Besides a comprehensive description of the crisis policy and its effects on the Serbian wheat market, we investigate how it influences the equilibrium and stability of the Serbian wheat market and its integration with the world market within a price transmission model. Applying a Markov-switching error correction model to weekly wheat grower prices in Serbia and world market prices, two states of the wheat market are identified. Our results suggest that although the long-run price elasticity did not change during the crisis, the market equilibrium was disrupted and the market...

Autores: Sparling,   Beth; Brethour,   Cher.
Environmental risk management is the process of measuring and/or assessing environmental risk and developing strategies to manage it. One strategy used in Canadian agriculture to manage environmental risk is the implementation of beneficial management practices (BMPs).     This paper provides a summary of a larger research project which explored farm profitability before and after participation in beneficial management practices, specifically those related to crop nutrients.  Based on producer perceptions and the assumptions used in this analysis, the results of this study indicate that the majority of the selected BMPs, including soil testing, minimum tillage, no-till and nutrient management planning, improved profitability for the representative farms....

Are U.S. Corn and Soybeans Becoming More Drought Tolerant?
Provedor de dados: 31
Autores: Yu,   Tian; Babcock,   Bruce A.
An objective drought index that measures the dry and hot conditions adversely affecting crop yields is used in a regression analysis to test whether corn and soybeans have become more drought tolerant. Results indicate that corn yield losses, whether measured in quantity terms or as a percentage of mean yield, have decreased. The null hypothesis that the absolute level of soybean yield losses due to drought has not changed cannot be rejected. But yield losses in percentage terms have decreased over time. Because drought is the primary cause of yield loss in the U.S. crop insurance program and because U.S. crop insurance rates assume that percentage of yield losses are constant over time, these results indicate that U.S. crop insurance rates in the Corn...

CIMMYT has invested a large and significant amount of public expenditures in wheat breeding research each year for several decades.  Estimates of the impact of the wheat breeding program on wheat yield increases provides information to scientists, administrators, and policy makers regarding the efficacy and the rate of return to these investments, providing important information for future funding decisions. Using CIMMYT test plot data from the Yaqui Valley in Mexico from 1990-2002, regression results indicate that the release of modern CIMMYT varieties has contributed approximately 53.77 kg/ha to yield annually.  The growing conditions of the experiment fields located in the Yaqui Valley approximate 40% of the developing world's wheat growing conditions....

Autores: Nagy,   Lajos.
This article has been made according to my dissertation in which I present some opportunity of risk analysis and risk management in the decision support of crop production. Plant production is one of the most hazardous agricultural enterprises. Among risk sources seasonal fluctuation of average yields plays an important role in the assessment of enterprises. Therefore, I analyzed the production risk of the produced crops in Hungary compared to the European Union’s, after that I took into consideration the production site’s circumstances as well. Decision-makers must possess such means, by which they can measure, oversee and manage the effects and consequences of risk. In crop production linear programming models can be used to determine the optimal crop...

Cereal price instability in Ethiopia: An examination of sources and policy options
Provedor de dados: 31
Autores: Shahidur,   Rashid; Meron,   Assefa.
Managing food price instability is a long standing policy challenge, which, with mixed experiences of agricultural price policy reforms, has re-emerged as a contemporary policy issue. This is particularly true for Ethiopia, where managing food price stability continues to be a formidable policy challenge. The objective of this paper is to examine the underlying causes of cereal price instabilities and to assess the policy options to manage them. It undertakes three tasks: (a) analyzes the sources and degree of cereal price instability, (b) discusses the viability of various policy options, and (c) critically reviews the country’s past, ongoing, and emerging policies for food price stabilization. The results show that the determinants of price...

In the Midwest, the adoption of precision farming technologies began in the early 1990s.  Research has produced  profiles of early adopters, evaluated adoption trends and has identified factors that influence the adoption and profitability of precision farming. Importantly, this information is available to producers, who are interested in precision farming  issues.  In addition, the Midwest regional agricultural industry, strong promoters of precision farming technologies, has gained the confidence of  farmers who now rely on them heavily for information on farming technologies. Precision farming in Arkansas, however,  is still in its infancy. Adoption levels lag far behind those in the Midwest.  Two reasons for this lag have been offered. First, some...

Why Don't Country Elevators Pay Less for Low Quality Wheat? Information, Producer Preferences and Prospect Theory
Provedor de dados: 31
Autores: Adam,   Brian D.; Hong,   Seung Jee.
Previous research found that country elevators that are the first in their area to grade wheat and pay quality-adjusted prices would receive above-normal profits at the expense of their competitors. Because of spatial monopsony, these early-adopting elevators would pass on to producers only 70% of the quality-based price differentials received from next-in-line buyers. If competing elevators also adopted these practices, profits for all elevators would return to near normal, and elevators would pass on to producers nearly all price differentials received from next-in-line buyers. However, that research could not explain why more elevators were not becoming "early adopters" by paying quality-adjusted prices. More recent research found that producers' risk...

VARIETY DEMAND WITHIN THE FRAMEWORK OF AN AGRICULTURAL HOUSEHOLD MODEL WITH ATTRIBUTES: THE CASE OF BANANAS IN UGANDA
Provedor de dados: 31
Autores: Edmeades,   Svetlana; Smale,   Melinda; Renkow,   Mitch; Phaneuf,   Daniel J.
Ugandan smallholder farmers produce the nation's major food crop using numerous banana varieties with distinctive attributes, while coping with important biotic constraints and imperfect markets. This empirical context motivates a trait-based model of the agricultural household that establishes the economic association between household preferences for specific variety attributes (yield, disease and pest resistance, and taste), among other exogenous factors, and variety demand, or the extent of cultivation. Six variety demands are estimated in reduced form, each in terms of both plant counts ("absolute" or levels demand) and plant shares ("relative" demand). Two salient findings emerge from the analysis: 1) the determinants of both absolute and relative...

Esta alavancagem do maracujá na região se deve às condições edafo-climáticas favoráveis e à necessidade de diversificar a economia em virtude da crise da cacauicultura. A sustentabilidade da cultura do maracujá depende das tecnologias e informações que possam ser disponibilizados aos produtores e que sejam gerados na própria região, a exemplo da análise do índice tecnológico da cultura e da sazonalidade dos preços, os quais são os objetos do presente trabalho. O estudo ficou concentrado nos municípios de Alcobaça, Prado e Teixeira de Freitas por serem os maiores produtores da...

Agricultural Trade and Freshwater Resources
Provedor de dados: 31
Autores: Reimer,   Jeffrey J.
Approximately 75% of all water used by humans goes towards food production, much of which is traded internationally.  This study formally models how this works in the case of crop agriculture, making use of recent advances in international trade theory and new data on the productivity by which countries use water for crop agriculture.  The strength of the model lies in its ability to predict, when there is a shock to the system, how trade between pairs of specific countries changes for products that use water intensively.  In one application of the model, international trade in final products is shown to be a means for countries to deal with short- and long-run shocks to water resources that are too big for one country to handle by itself in isolation.  In...

INCENTIVE CONTRACTS TO MEET FUNCTIONAL CHARACTERISTICS IN WHEAT PURCHASING -- SUMMARY
Provedor de dados: 31
Autores: Wilson,   William W.; Maxwell,   Brett J.; Dahl,   Bruce L.
Consistency of functional characteristics in hard red spring (HRS) wheat is a concern confronting sellers and buyers.  This research analyzes contract incentives for importers with respect to cost and potential risk of acceptance.  A principal-agent framework is utilized to examine contract incentives.  In the principal-agent contract, the principal offers the contract, the agent rejects or accepts the contract, and then decides how much effort to apply.  All this is subject to risk for the agent and moral hazard for the principal.  An example is presented, for which equilibrium contract terms are a base price of 454 cents per bushel for low quality wheat and a premium of 36 cents per bushel if high quality is achieved.  The premium for high quality is...

Tedera (Bituminaria bituminosa C.H.Stirt var. albomarginata) is a drought tolerant perennial legume originating in the Canary Islands. This study evaluates the potential role and value of tedera in dryland mixed crop and sheep production systems in southern Australia. Regional variants of the bio-economic model MIDAS are used to assess tedera in farming systems at two locations. The analysis considers the quantity and quality of feed produced by tedera, the ability of other forages to complement or substitute for tedera and its impact on meat versus wool-producing sheep flocks. The results indicate that tedera offers the potential to increase farm profits by up to 26% and be grown on ~28% of a low rainfall mixed enterprise farm. On a high rainfall mixed...

PLANTING DECISIONS AND UNCERTAIN CONSUMER ACCEPTANCE OF GENETICALLY MODIFIED CROP VARIETIES
Provedor de dados: 31
Autores: Saak,   Alexander E.; Hennessy,   David A.
There exists much uncertainty about consumer attitudes towards genetically modified foods.  If it happens that sufficient (insufficient) acres are planted under non-modified seed to meet post-harvest demand, then a price premium will not (will) emerge for the non-modified varieties.  A non-linearity originates in the fact that a price premium may be supported.  This non-linearity interacts with the extent of demand uncertainty to determine equilibrium varietal plantings and the probability that post-harvest varietal prices will differ.  Also, as planting approaches signals will be received by growers about the nature of demand they will be planting into.  We show how the non-linearity affects the order on the types of signals that risk-neutral growers will...

Factors Affecting Hedging Decisions Using Evidence from the Cotton Industry
Provedor de dados: 31
Autores: Isengildina,   Olga; Hudson,   Darren.
Few farmers utilize futures and options markets to price their crops despite significant educational efforts. This study seeks to analyze producer hedging behavior within the framework of the overall marketing behavior. Producer marketing behavior is modeled as a simultaneous choice between cash sales, cooperative marketing and forward contracts, and hedging. A multinomial logit model is used for empirical estimation using data from a survey administered to a sample of cotton producers from across the U.S. The most important factors that explain the use of forward pricing by cotton producers are producer preferences, farm size, use of crop insurance, risk aversion, income from government payments and off-farm income. Risk aversion, off-farm income, crop...

Policy reform and farmers' wheat allocation in rural China: a case study
Provedor de dados: 31
Autores: Buschena,   David E.; Smith,   Vincent H.; Di,   Hua.
Market-oriented policy reforms often have important effects on farm-level grain production and utilisation decisions in developing countries. China’s grain farmers are of particular interest because of China’s importance in world grain markets and because of China’s recent major agricultural policy advances and retrenchments. An empirical evaluation of market liberalisation among farmers located in two provinces in China on farm-level wheat consumption, market sales and on-farm storage during 1994 is presented. The results indicate that policymakers should account for such changes in farm household behaviour in designing and assessing the consequence ofmarket liberalisation programs for agricultural sectors in developing countries.

EFFICIENCY OF WIND INDEXED TYPHOON INSURANCE FOR RICE
Provedor de dados: 31
Autores: Banerjee,   Chirantan; Berg,   Ernst.
Index-based weather insurances are innovative tools for mitigating weather risks in agriculture. Several donor agencies and development organisations are investing substantially to propagate these programmes in developing countries. However, often due to high basis risks, these products mitigate risk only through diversification effect, thereby defeating the intended purpose. Besides, they send confusing messages to the farmers regarding the very concept of insurance. Therefore, this paper investigates the efficiency of two such index-based weather insurances in Philippines, designed to mitigate rice yield loss caused by strong typhoon winds. The insurance products are designed assuming negative linear correlation between wind speed and rice yield. To...

Safety Nets or Trampolines? Federal Crop Insurance, Disaster Assistance, and the Farm Bill
Provedor de dados: 31
Autores: Goodwin,   Barry K.; Rejesus,   Roderick M.
We review the implications of the 2007 Farm Bill for the risk management dimensions of U.S. agriculture and policy. Legislative proposals suggest significant changes in risk management policy, including the introduction of state or national revenue insurance. We also pursue an empirical analysis of the interrelationships of crop insurance, disaster relief, and farm profitability. We find an inverse relationship between disaster assistance and insurance purchases. Our analysis also suggests that farmers that buy insurance and that receive disaster payments tend to have higher returns to farming.

HEDGING PRICE RISK IN THE PRESENCE OF CROP YIELD AND REVENUE INSURANCE
Provedor de dados: 31
Autores: Mahul,   Olivier.
The demand for hedging against price uncertainty in the presence of crop yield and revenue insurance contracts is examined for French wheat farms. The rationale for the use of options in addition to futures is first highlighted through the characterization of the first-best hedging strategy in the expected utility framework. It is then illustrated using numerical simulations. The presence of options is shown to allow the insured producer to adopt a more speculative position on the futures market. Futures are shown to be performing, in terms of willingness to receive. Options are weakly performing when futures markets are unbiased, while they are more performing when futures markets are biased.

Adoption and Impacts of Zero-Tillage in the Rice-Wheat Zone of Irrigated Punjab, Pakistan
Provedor de dados: 31
Autores: Farooq,   Umar; Sharif,   Muhammad; Erenstein,   Olaf.
This study documents the adoption and impacts of zero-tillage (ZT) wheat in the ricewheat systems of Pakistan’s Punjab province primarily drawing on a detailed empirical survey of 458 rice-wheat farmers. Our random stratified sample revealed 19% to be ZT wheat adopters and a similar share of the wheat area in the surveyed communities to be under ZT. The study suggests that diffusion has stagnated and also flags the issue of disadoption (14%). ZT adopters, non-adopters, and disadopters differ significantly in terms of their resource bases, with adopters typically showing the most favorable values. ZT drastically reduces tractor operations in farmers’ ZT wheat fields from an average of 8 passes to a single pass, implying a saving of 7 tractor hours and 35...

The processes of agricultural policy decision-making in the East Asian economies of Japan, Taiwan, and Korea are characterized by the complex interactions of competing special interest groups in their respective political arenas. An analytical model is designed to investigate how adjustments in rice price policies are endogenously related to the political economic forces associated with macroeconomic changes. The model is tested against the case of Korean rice price policy, which has not been satisfactorily explained in earlier modeling efforts. A political preference function is used to estimate the relative political weights of producers, consumers, and government over a 25-year period (1961-1985) during which major macroeconomic changes occurred.

REFORM OF THE CANADIAN WHEAT BOARD: A “MADE IN CANADA” APPROACH TO MARKETING GRAIN
Provedor de dados: 31
Autores: Pedde,   Richard; Mirus,   Rolf.
The debate continues: whether or not single desk selling of Western Canadian grain provides the best return to producers. It is methodologically difficult to show that better returns may have been foregone in the past, yet the experience in Illinois suggests that, absent the CWB, farmers could also achieve worse results. While this battle – a battle that is in part ideological in nature – has been taking place, the world has moved forward and new services markets have evolved. There may indeed be $20 bills on the sidewalk that can be picked up by moving with the world – without, for the time being, abandoning the single desk. In this brief discussion paper we argue that the Canadian Wheat Board (CWB) can improve its performance through increased recourse...

The quality factor has been playing important role for the competitiveness of the enterprises. Some authors believe that, under the aegis of the market globalization, the quality reaches its highest level of importance in the business decision process and turns out to be the passport for opening the most challenging markets and for upholding the niches in the more competitive markets. However, systems or quality programs generate costs that, usually, are unknown for the firms. In Brazil, the literature on the costs of the quality lacks more comprehensive...

NE- 165 Case Study : CANOLA AS AN EMERGING INDUSTRY: A Processor and Producer Perspective
Provedor de dados: 31
Autores: Coaldrake,   Karen; Sonka,   Steven T.
The canola industry in the United States has been very small with a limited canola oil demand being met through imports. However, an apparent increase in consumer demand for more healthful alternatives to traditional vegetable oils has sparked an interest among domestic processors desiring to be among the first entrants to a U.S. canola oil market. Processor interest has in turn led to some producer experimentation with the crop. This case study documents the early activities of U.S. Canola Processors (USCP), one of two companies processing the U.S. crop, and Ralph King, a Central Illinois canola producer. USCP, a joint venture of Central Soya and Calgene, describes their role in terms of "building an industry," according to General Manager Larry Horn. The...

Sesamum, once an important oilseed crop, has been loosing its importance on the cropping map of the state agriculture, owing to favourable production and marketing environment for other crops like paddy. The study has reported the trends in area, production and yield of sesamum, its relative profitability, factors affecting productivity and various constraints inhibiting its growth in the state. The area under sesamum that had declined over the years, has shown a little progress due to oilseeds development programmes, initiated by the Govt. during late-1980s. On the comparative economics front, sesamum has been found to provide lower returns as compared to paddy. The benefit cost ratio of sesamum has been found to be 1.36 which shows its profitability in...

THE EFFECT OF A CHANGING MARKET MIX IN SEED CORN ON INVENTORY COSTS
Provedor de dados: 31
Autores: Dooley,   Frank J.; Kurtz,   Matthew M.
Changing product characteristics are causing U.S. seed corn companies to reevaluate their inventory strategies.   A simulation model based upon the Economic Order Quantity model is built in @Risk to reflect a shortened product life cycle and product proliferation.  Inventory costs levels increase because of increased uncertainty of demand.  Empirical results find that shortening the product life cycle and expanding the product line increases total inventory costs by 120.8%, increases the average inventory level (primarily due to added safety stock) by 56.2%, and increases the cost of carryover, stockout cost, and safety stock cost by 143, 165, and 119 %, respectively.

New Zealand’s success in raising agricultural productivity has been accompanied by higher input use, leading to adverse effects on the environment. Until recently, analysis of farm performance has tended to ignore such negative externalities. The current emphasis on environmental issues has led dairy farmers to target improvements in both environmental performance and productivity. Therefore measuring the environmental performance of farms and integrating this information into farm productivity calculations should assist informed policy decisions which promote sustainable development. However this is a challenging process since conventional environmental efficiency measures are usually based on simple input and output flows but nitrogen discharge is a...

DEMAND FOR PLANT NUTRIENTS IN TENNESSEE DISAGGREGATED BY MIXED FERTILIZERS AND DIRECT APPLICATION MATERIALS
Provedor de dados: 31
Autores: Roberts,   Roland K.; Garrod,   Peter V.
When obtaining nitrogen (N), phosphate (P) and potash (K), purchasing decisions concerning the quantity and the form of each plant nutrient must be made.  Logit models are estimated for the choice-of-form decision by considering those variables influencing the probability that plant nutrients will be purchased in Tennessee as part of a mixed fertilizer or as direct application materials.  Parameter and elasticity estimates can be used by fertilizer manufacturers and distributors to anticipate changes in the composition of demand for plant nutrients in Tennessee.

THE FOOD CHALLENGE IN THE SENEGALESE RURAL ECONOMY AN ANALYSIS OF THE DOMESTIC CEREALS PROMOTION POLICY
Provedor de dados: 31
Autores: Gaye,   Matar.
Since the colonial era, the expansion of the Senegalese economy was greatly sustained by the agricultural sector in which more than three-fourths of the total population were involved.  A 2.3 percent average annual growth of total production during the sixties matched the speed at which the agricultural population was growing and the rural economy was engaged in a kind of equilibrium path.  During the late sixties and early seventies, the situation began to change with an agricultural production growth rate dropping to the neighborhood of 1.3 percent against 2.8 percent for total population.  Such a situation which is prevailing at the present time is seriously striking if we know that the agricultural sector should produce not only enough food for a...

Asian Elephants as Agricultural Pests: Damages, Economics of Control and Compensation in Sri Lanka
Provedor de dados: 31
Autores: Bandara,   Ranjith; Tisdell,   Clement A.
Despite growing attention to crop and property damage caused by the Asian elephant, uncertainty exists about the magnitude of this problem. This paper explores the nature and magnitude of this problem of Sri Lanka. An economic analysis of individual farmers’ decisions to control elephants is provided. Government policies to assist farmers to cope with the elephant pest problem are assessed. Appropriate compensation schemes for farmers are seen as potentially more effective for conserving elephants in Sri Lanka than legal prohibitions on killing of elephants. Issues raised have wider relevance than merely to Sri Lanka or Asian elephants.

Uncertainty aversion in Australian regulation of agricultural gene technology
Provedor de dados: 31
Autores: Gray,   Emily M.; Ahmadi-Esfahani,   Fredoun Z.
There is potential for over-provision of environmental harms and under-provision of environmental benefits associated with GM crops. As a result, strong public regulation is needed to ensure that full social values are considered. However, one reason for opposition to GM crops is a lack of public trust in regulatory institutions and science, and the limited opportunities afforded to public-participation and nonscientific concerns. We aim to demonstrate the trade-off between social cost and managing the risks of gene flow arising from environmental release of GM canola in Australia, using the framework of a probabilistic risk assessment and safety-rule decision mechanism.

Provedor de dados: 31
Autores: Roosen,   Jutta; Hennessy,   David A.
Antibiotics are used in fruit production to control fire blight, a bacterial disease of fruit trees that causes yield losses and eventually tree death.  Fearing the development of widespread antibiotic resistance, scientists and public health officials are becoming increasingly concerned about antibiotics use in agriculture.  A framework is developed for assessing the impacts of changes in tree damage risk following a ban on antibiotics use in the apple industry.  Allowing for entry and exit, a long-run analysis of replanting dates and equilibrium prices is provided, as well as an estimate of the welfare impacts of a ban on antibiotics.

Autores: Lankoski,   Jussi E.; Ollikainen,   Markku; Uusitalo,   Pekka.
We study from economic and environmental angles under what conditions no-till technology is socially optimal. We demonstrate theoretically that if yield under no-till is equal to or greater than under conventional technology, its adoption is socially optimal provided that herbicide runoff damages under both technologies are close enough. Finnish data shows, however, that only in one case out of three no-till provides higher social returns. In terms of nutrient runoffs no-till performs better than conventional technology. No-till reduces surface runoffs of nitrogen by 58%, and surface runoffs of particulate phosphorus by 70% relative to conventional technology, but causes more than three times higher dissolved phosphorus surface runoffs. The amount of total...

Autores: Kourouma,   Aboubacar.
The purpose of this paper is to analyze some effects of export and food crop strategies on farm income and food self-sufficiency at the household level in the Eastern and upper Casamance regions of Senegal.  The objectives of the government of Senegal include food self-sufficiency and export crop expansion through crop diversification.  Over the last twenty years, extension programs have emphasized the introduction of cotton and maize.  Although maize seems to have found its way easily in the existing farming system, the performance of cotton is less clear.  After an initial rapid expansion, cotton acreage and production started to decline from the mid 70's.  This raises questions about the lont-term suitability of cotton and emphasizes the need for...

IMPROVED SYSTEMS OF RICE FARMING IN ZAIRE:  A COMPARISON OF UPLAND AND IRRIGATED RICE
Provedor de dados: 31
Autores: Kamuanga,   Mulumba.
Cassava, maize, rice, groundnuts and plantains constitute the main food crops in Zaire.  Rice is a staple food in several regions though its consumption has thus been concentrated in the urban centers.  The Department of Agriculture had estimated that rice consumption increased at an annual rate of 2.1 percent for the 1971-74 period and it has also predicted that this rate may reach 9.1 percent by the end of the decade.  One of Zaire's key problems is to meet its domestic demand for rice. The government policy of fixing annual hectarage targets for rice and other crops to be achieved through the opening of new land and through exhorting farmers to grow more rice has not succeeded in closing the gap between supply and demand. The focus now is on development...

The main objective of this study is to evaluate the comparative advantage of olive oil production in Albania using Policy Analysis Matrix (PAM) method. The result indicates that olive oil production in Albania is profitable for the producers. Whereas the DRC ratio equals to 2.2, meaning that olive oil production in Albania does not have a comparative advantage for the given situation of production, prices and technology. This means that while it is profitable for private producers to manufacture olive oil for the domestic market, it does not have a comparative advantage with other EU countries. In order for Albania to develop an olive oil industry comparable to neighboring countries with similar climatic and soil conditions, the country will need to...

Market power and subsidies in the Indonesian palm oil industry
Provedor de dados: 31
Autores: Chalil,   Diana.
Cooking oil is known as an essential commodity in Indonesia. Having such an important role, the Indonesian government often interfered the cooking oil market to assure its price remain low. To do so, the government uses a subsidy policy as one of its instruments. A dynamic duopoly model is applied to evaluate the impact of subsidies given the structure of the industry. Estimation results suggest an evidence of both an increase in the consumer surplus but a decrease in aggregate welfare due to market power. A possible reason is proposed, but, in order to obtain a clear explanation, further research is required.

Land degradation, in the form of soil erosion and nutrient depletion, threatens food security and the sustainability of agricultural production in many developing countries. Governments and development agencies have invested substantial resources in promoting soil conservation practices, in an effort to improve environmental conditions and reduce poverty. However, very limited rigorous empirical work has examined the economics of adopting soil conservation technology. This paper investigates the impact of stone bunds1 on crop production value per hectare in low and high rainfall areas of the Ethiopian highlands using cross-sectional data from more than 900 households having multiple plots per household. We use modified random effects models, stochastic...

Though Zambia has considerable agricultural potential, the sector’s contribution to growth and poverty reduction has been limited. The sector remains one of the most important employers of labour and remains the main source of livelihood for most rural households in Zambia. Thus key development challenge facing Zambian agriculture over the past two decades has been how it can effectively contribute to poverty reduction and broad-based economic growth. Agricultural commercialisation and surplus production, as revealed by nationally representative farm surveys, in the country has remained concentrated with only about 5% of Zambia’s small- and medium-scale farmers produce half of the marketed surplus. Meanwhile at least half of the smallholder farms sell...

Chemical pesticides will continue to play a role in pest management for the future. In many situations, the benefits of pesticide use are high relative to the risks or there are no practical alternatives. The number and diversity of biological sources will increase, and products that originate in chemistry laboratories will be designed for particular target sites. Innovations in pesticide delivery systems in plants promise to reduce adverse environmental impacts even further. The correct use of pesticides can deliver significant socioeconomic and environmental benefits in the form of safe, healthy, affordable food; and enable sustainable farm management by improving the efficiency with which we use natural resources such as soil, water and overall land...

Improved Program Planning Generates Large Benefits in High Risk Crop Farming – A Profitable Application of Time Series Models and Stochastic Optimization
Provedor de dados: 31
Autores: Musshoff,   Oliver; Hirschauer,   Norbert.
Agricultural production relies to a great extent on biological processes in natural environments. In addition to volatile prices, it is thus heavily exposed to risks caused by the variability of natural conditions such as rainfall, temperature and pests. With a view to the apparently lacking support of risky farm production program decisions through formal planning models, the objective of this paper is to examine whether, and eventually by how much, farmers’ “intuitive” program decisions can be improved through formal statistical analyses and stochastic optimization models. In this performance comparison, we use the results of the formal planning approach that are generated in a quasi ex-ante analysis as a normative benchmark for the empirically observed...

Southeastern Peanut-Production Cost Efficiency Under the Quota System:  Implications for the Farm-Level Impacts of the 2002 Farm Act
Provedor de dados: 31
Autores: Nadolnyak,   Denis A.; Fletcher,   Stanley M.; Hartarska,   Valentina M.
In the article, stochastic frontier analysis of peanut-production efficiency in the Southeastern region of the United States is conducted with a view of assessing the likely farm-level impacts of the 2002 Farm Act.  Results indicate that , although quota ownership did not significantly impact inefficiency, it is likely that limitations on the quota’s transferability to areas with better growing conditions were a significant cause of inefficiency.  The acreage shifts and improved yields following the passage of the 2002 Farm Act support this conclusion.  Certain farm characteristics, such as farm size and operator’s education and age, were also important for efficiency.

This paper examines different cropping practices, cost structures and gross margins for conventional table potato cropping in 6 different regions within the European Union: Czech Republic, Denmark, Italy, Poland, Portugal and Slovakia. Findings from this study show that potato cropping practices varies significantly between the various countries with major differences in yield and costs. Italy and Denmark are the two regions with highest gross margins due to high yields and revenues. Poland is by far the largest potato producing country among the 6 countries. However, the production is primarily based on small scale farming with low yields and economic revenues.

A study of irrigated strip-till soybean production compared gross margins over nematicide expense for a continuous triticale-soybean system versus a two-year rotation system alternating triticale-soybean with triticale-cotton. Half of the replicated plots under each system received nematicide treatment. Gross margins were calculated using recorded yields and Georgia average market prices by marketing years. Mean gross margins for untreated plots were not significantly different between crop-sequence systems. Within each system, however, mean gross margins were significantly higher for plots not receiving nematicide treatment versus treated plots, even when treated plots produced greater yields.

Herbicide resistance has become a major problem in Australian dryland agriculture. This situation has resulted from the repeated use of herbicides in place of the traditional weed control provided by cultivation and grazing. Farmers have addressed the problem of herbicide resistance by adopting a system of integrated weed management that allows weed control with a range of different techniques and herbicides. One of the non-chemical methods being considered by farmers is “green manuring”, which involves ploughing a healthy growing crop or pasture into the soil in order to prevent weed seed production and provide other benefits. In this study, the trade-offs between the effective weed control and biological benefits provided by green manuring and the large...

Autores: Satolo,   Luiz Fernando; Diehl,   Daiane.
O cultivo da cana-de-açúcar tem apresentado um expressivo crescimento ao longo de todo o território nacional, com destaque para a região Centro-Sul. O objetivo desse estudo é investigar como aspectos regionais (ou seja, a adoção de inovações tecnológicas) – representados pela evolução da produtividade nos principais Estados produtores – e nacionais (ou seja, as condições de mercado) – representados pela evolução do preço médio de açúcar e álcool – têm contribuído para a expansão da agroindústria canavieira no Brasil. A oferta dos 10 Estados brasileiros com maior produção de cana-de-açúcar foi estimada através de um modelo de regressões aparentemente não-relacionadas (SUR). Os dados anuais abrangeram as safras de 1990/91 a 2004/05. Exceto por Pernambuco e...

Hybrid Rice: Economic Assessment of a Promising Technology for Sustainable Food Grain Production in Bangladesh
Provedor de dados: 31
Autores: Azad,   Md Abdus Samad; Mustafi,   B.A.A.; Hossain,   Mahabub.
Hybrid rice, one of the viable and proven technologies has been considered as a new frontier to increase rice production for meeting growing demand for staple food in Bangladesh. Using farm survey data this paper examines comparative profitability of hybrid and inbred rice cultivation and estimates a Stochastic Frontier Function to determine the effect of key variables on farm efficiency. Results show that hybrid rice gives substantially higher yield as well as net return compared to inbred rice which leads to increase and sustainable growth of food grain production. Analysis of Stochastic Frontier model shows hybrid rice farms are technically more efficient than inbred.

From Ecology to Economics: The Case Against CO2 Fertilization
Provedor de dados: 31
Autores: Erickson,   Jon D.
The effects of increasing concentrations of atmospheric carbon dioxide (C02) on agricultural yields are analyzed. It is argued that any positive effects on yields from C02 fertilization, demonstrated in controlled experiments, would be weak in farm conditions given water and nutrient limits. Furthermore, possible benefits would be more than offset by predicted consequences of climate change, ozone depletion, and additional gases created from fossil fuel combustion. The impact of including C02 fertilization on crop yield and economic welfare predictions is evaluated. The policy distorting potential of fragile claims is stressed

EVIDENCE FOR A WEATHER PERSISTENCE EFFECT ON THE CORN, WHEAT AND SOYBEAN GROWING SEASON PRICE DYNAMICS
Provedor de dados: 31
Autores: Stevens,   Stanley C.
The growing season weather in the corn, wheat and soybean production areas of the United States is an important determinant of the U.S. supply of these commodities.  The weather and climatology literature strongly suggest that during the summer months there is a degree of persistence in the North American weather patterns.  Given this nonrandom character of weather and given that the corn, wheat and soybean belts are geographically concentrated enough to be dominated by a regional weather phenomenon, their futures markets are hypothesized to reflect this assimilation of nonrandom weather information as nonrandom price fluctuations.  An empirical test of this question is the subject of this paper.

An Empirically-Grounded Comparison of the Johnson System versus the Beta as Crop Yield Distribution Models
Provedor de dados: 31
Autores: Ramirez,   Octavio A.; McDonald,   Tanya U.
Previous research established that the expanded Johnson system can accommodate any theoretically possible mean-variance-skewness-kurtosis combination. Therefore, it has been hypothesized that this system can provide for a reasonably accurate modeling approximation of any probability distribution that might be encountered in practice. In order to test that hypothesis, this manuscript develops a more flexible expanded form of the Beta distribution which, in its original form, has been widely used to model and simulate crop yields for risk analysis. Empirically grounded evaluations suggest that the Johnson system can model a variety of typical yield data-generating processes that are based on the Beta distribution much more precisely than the Beta can model...

The incidence of post-harvest problems among small farmers surveyed in three regions of the Limpopo Province
Provedor de dados: 31
Autores: Randela,   Rendani.
High yielding varieties and new production technology have vastly increased the world's agricultural production and provided rural incomes and affordable food for large parts of the population. While production research has received considerable attention, until recently, post harvest activities have not received much attention. Post harvest research has significant contribution towards the alleviation of poverty, food insecurity and the sustainable use of resources. The objective of the paper is to assess the post-harvest constraints affecting main staple grain crops in three regions of the Limpopo Province. Some of the most common post harvest constraints revealed by the study are, weevils, rodents and transport for produce from the field to home...

Most Rwandan coffee is currently grown and processed the same way it was a decade ago.  Consequently, Rwanda’s coffee production and marketing system has not been able to keep up with  changes in the global market for high quality coffee. Given world market gluts of relatively poor quality coffee, Rwanda is now exporting a product that fetches low prices. Despite the challenges in coffee marketing and production, coffee remains one of Rwanda’s most important official sources of foreign exchange and the drop in production is of major concern to both the public and private sectors. In an effort to assist decision makers in the coffee sector better understand factors affecting farmers’ production decisions and their attitudes about coffee, the FSRP fielded a...

Autores: Priewe,   Steven R.; Wilson,   William W.
Grain hauling railroads began offering shipping alternatives in the late 1980s that have made transportation decisions more strategic. Shippers now confront alternatives ranging from nearby and unguaranteed ordering to various durations of forward and guaranteed shipment.  A dynamic stochastic simulation model was developed to analyze grain shipping and merchandising strategies that integrate these alternatives.

Washington Biofuel Feedstock Supply under Price Uncertainty
Provedor de dados: 31
Autores: Zheng,   Qiujie; Shumway,   C. Richard.
Biofuels, as alternative transportation fuels, are now being used globally. Taking advantage of in-state feedstock supply is an efficient way to stimulate in-state biofuel industries and the local economy. This paper uses the mean-variance model of utility maximization to estimate supply equations for major biofuel feedstock crops in Washington. We consider price risk, examine the comparative statics results of the model, and use the results to draw important decision-making implications for Washington farmers who are considering production of biofuel feedstocks. Of three potential feedstock crops, only one shows immediate promise in Washington.

The unprecedented growth in crop yields and agricultural total factor productivity over the past 70 years owes much to a series of biological innovations embodied in seeds, beginning with the development of hybrid crops in the United States in the early part of the 20th century, continuing with the adoption of high-yielding varieties during the Green Revolution of the 1960s and 1970s, and more recently, modern biotechnology. Throughout this period, the seed industry evolved, as small businesses gave way to larger enterprises that integrated plant breeding, production, conditioning, and marketing functions. The industry was further shaped by widespread mergers and acquisitions in the latter part of the century, rapid growth - in private research and...

Does On-Farm Quality Assurance Pay?  A Cost-Benefit Analysis of the Grainsafe Program
Provedor de dados: 31
Autores: Karaca,   Umit; Maier,   Dirk E.; Alexander,   Corinne E.
Since the introduction of genetically modified (GM) crops, the commodity grain system has been under pressure to segregate GM and non-GM crops.  Starting at the level of the grain handler, members of the grain supply chain have successfully used quality assurance and identity preservation programs to segregate non-GM crops.  Producers delivering high value, identity preserved crops have become interested in implementing these quality management systems at the farm level.  We conduct a cost-benefit analysis that shows that quality assurance program may be profitable for producers, depending on their farm size and equipment management strategy.

Land tenure and farm management efficiency: the case of paddy and cinnamon production in customary land areas of Sumatra
Provedor de dados: 31
Autores: Suyanto,   S.; Tomich,   Thomas P.; Otsuka,   Keijiro.
This study attempts to identify the impacts of land tenure institutions on the efficiency of farm management based on a case study of lowland paddy (rice) and upland cinnamon production in customary land areas of Sumatra. While the traditional joint‐family ownership system is found to exist in paddy land, more individualised ownership systems are widely observed in upland areas. Yet, we found no statistical evidence that residual profit per unit of land is affected by land tenure institutions in either the lowlands or uplands, indicating that the prevailing land tenure institutions are equally conducive to efficient farm management.

Policies for the regulation of coexistence between GM and conventional crops
Provedor de dados: 31
Autores: Ceddia,   M. Graziano; Bartlett,   Mark; Perrings,   Charles.
Pollen-mediated gene flow is one of the main concerns associated with the introduction of genetically modified (GM) crops, since growers of GM varieties normally do not take into account its possible impact on conventional and organic growers therefore generating negative externalities. Should a premium for non-GM varieties emerge on the market, 'contamination' with GM pollen would generate a revenue loss for growers of non-GM varieties. The existence of such externalities has led the European Union (EU) to put forward the concept of coexistence in order to guarantee farmers' freedom to plant both conventional and GM varieties without generating economic losses to conventional farmers. The first part of this paper develops a simple economic model analysing...

Autores: Egbendewe-Mondzozo,   Aklesso; Swinton,   Scott M.; Izaurralde,   R. Cesar; Manowitz,   David H.; Zhang,   Xuesong.
This paper introduces a spatial bioeconomic model for study of potential cellulosic biomass supply at regional scale. By modeling the profitability of alternative crop production practices, it captures the opportunity cost of replacing current crops by cellulosic biomass crops. The model draws upon biophysical crop input-output coefficients, price and cost data, and spatial transportation costs in the context of profit maximization theory. Yields are simulated using temperature, precipitation and soil quality data with various commercial crops and potential new cellulosic biomass crops. Three types of alternative crop management scenarios are simulated by varying crop rotation, fertilization and tillage. The cost of transporting biomass to a specific...

Olive oil is possibly the single globally consumed and traded product most closely linked to the Mediterranean; non-Mediterranean countries account for less than 2.5 per cent of world production. The paper addresses recent trends in the olive oil world market and the current structure of trade. With respect to existing analyses, its value added is in the level of detail at which the analysis of current trade is conducted, in particular by considering bilateral olive oil trade flows disaggregated with respect to its quality. The main conclusion reached is that the key factors for the future of the market are developments in demands and in the imperfectly competitive structure of the industry, while supply factors and expected changes in trade policies,...

Corn stover harvest and transport cost functions were estimated for two harvest operations for a proposed biomass-to-ethanol conversion facility located in southern Minnesota, USA.  This work presents an alternative methodology to estimating corn stover quantities and harvest costs at the county level, taking into account county-specific yields, transportation distances, erosion constraints, machinery specifications, and other key variables.  Monte Carlo simulation was also used to estimate the probability distribution of costs under alternative assumption on key parameters whose values vary widely in the literature.  Marginal stover cost for 50MM gal/year of ethanol output was estimated at $54/dt ($0.77/gal ethanol) for the more intensive harvest method...

We examined four evolution paths of the biofuel sector using a partial equilibrium world agricultural sector model in CARD that includes the new RFS in the 2007 EISA, a two-way relationship between fossil energy and biofuel markets, and a new trend toward corn oil extraction in ethanol plants. At one extreme, one scenario eliminates all support to the biofuel sector when the energy price is low, while the other extreme assumes no distribution bottleneck in ethanol demand growth when the energy price is high. The third scenario considers a pure market force driving ethanol demand growth because of the high energy price, while the last is a policy-induced shock with removal of the biofuel tax credit when the energy price is high. Standard results hold where...

Is the Green Revolution Vanishing? Empirical Evidence from TFP Analysis for Rice
Provedor de dados: 31
Autores: Adlas,   J.; Achoth,   Lalith.
A serious concern has been raised recently on the long run sustainability of the productivity effects of Green Revolution technologies in the light of decelerating trend in the yield growth of rice since the mid 1980s under irrigated ecosystem. However, the changes in physical yield are not true measures of productivity from efficiency perspective. Total factor productivity (TFP) is a true measure of economic efficiency of any technology impact. The paper addresses the crucial issue of "is green revolution vanishing" empirically by analyzing TFP for rice in India. Results suggest that various modern technologies (such as modern cultivars) adopted by the farmers over the period have continued to make considerable impact on rice productivity growth-as...

A common perception is that the value of Bt corn arises from two components-Bt corn increases expected profit and reduces profit variability.  This perception encourages farmers and the policy makers to add a risk benefit to estimates of the value of Bt corn to account for the variability reduction.  However, a conceptual model generates a useful decomposition of the value of Bt corn and a condition determining the impact of Bt corn on profit variability.  An empirical model finds that Bt corn increases profit variability and thus decreases the value of Bt corn by 10-25% depending on risk preferences.

Measuring market integration for apples on the South African fresh produce market: a threshold error correction model
Provedor de dados: 31
Autores: Uchezuba,   David Ifeanyi.
Apples constitute the bulk of deciduous fruit produced in South Africa, i.e. in 2000, apples made up the largest percentage of the deciduous fruit crop (43%). From 991/92 to 2002/03 production averaged 574 850 tons per annum with a standard deviation of 43 922 tons. The average distribution of the apple crop between the local market, exports and processing is more or less even. Because of its potential lucrative nature much emphasis in the apple industry is afforded to exports, but relatively little is known about how price transmission takes place on the domestic fresh produce markets (FPMs). Moreover, it is increasingly recognized that the formulation of market-enhancing policies to increase the performance of the local market requires a better...

Economic Impacts of Soybean Rust on the US Soybean Sector
Provedor de dados: 31
Autores: Gomez,   Miguel I.; Nunez,   Hector M.; Onal,   Hayri.
The spread of Asian Soybean Rust (ASR) represents a real threat to the U.S. soybean sector. We assess the potential impacts of ASR on domestic soybean production and commodity markets as well as the competitive position of the US in the soybean export market. We develop a mathematical stochastic dynamic sector model with endogenous prices to assess the economic impacts of ASR on US agriculture. The model takes into account the disease spread during the cropping season, the inherent uncertainty regarding the risk of infection, and the dichotomous decisions that farmers make (no treatment, preventive treatment, and curative treatment) facing the risk of infection. Our results suggest substantial impacts from potential ASR spread on agricultural output,...

Adoption of Improved Maize Seed by Smallholder Farmers in Mozambique
Provedor de dados: 31
Autores: Zavale,   Helder; Mabaya,   Edward T.; Christy,   Ralph D.
The objective of this paper is to investigate factors influencing the adoption of improved maize seed by smallholder farmers in Mozambique. The data used in this study were obtained from a national random sample of 4,908 smallholder farmers conducted by the Ministry of Agriculture and Rural Development in 2002. Using Probit and Logit models, the main factors influencing adoption of improved maize seed were identified. The results of this analysis indicate that fifteen out of twenty five factors are significantly found to be the determining factors influencing the probability of adopting improved maize seed. To increase the likelihood of adopting improved maize seed, policy makers should put more emphasis on improving rural infrastructures and providing...

Examining AWB’s market power in the international wheat market
Provedor de dados: 31
Autores: Chang,   Hui-Shung (Christie); Martel,   William; Berry,   Robert.
The Australian wheat marketing system has been through a number of stages of deregulation in recent years. However, the AWB still maintains the monopoly selling rights of Australian wheat exports. The AWB and its supporters justify the single desk by arguing that the monopoly power enables them to gain a higher price in the export markets. Opposition to the single desk argues that Australia does not produce enough wheat to influence prices. The objective of this study is to test the market power hypothesis by examining the quantity - price relationship of Australian wheat exports and the stability of this relationship over time using annual data from 1961 to 2000.

Efficiency and Pooling in Western Cape Wine Grape Production
Provedor de dados: 31
Autores: Conradie,   Beatrice; Cookson,   Graham; Thirtle,   Colin G.
This paper uses a stochastic frontier and inefficiency model to test the efficiency of grape production in the Western Cape. The data covers two panels of wine grape farms (34 in Robertson and 36 in Worcester) for 2003 and 2004 and 37 table grape farms in De Doorns for 2004 only. Tests show that Cobb Douglas stochastic production frontiers, with variables to explain the inefficiencies are an appropriate representation of the five individual samples. The stochastic frontier results indicate that output can be explained by land, labour and machinery and that efficiency cab be affected by labour quality, age and education of the farmer, location, the percentage of non-bearing vines and expenditures on electricity for irrigation. These data is sufficiently...

INCOME TAX REFORM AND CALIFORNIA ORCHARD DEVELOPMENT
Provedor de dados: 31
Autores: Carman,   Hoy F.
The effects of requiring capitalization of citrus and almond orchard development expenses on acreage, production and product prices for seven California orchard and vine crops are estimated.  Acreage and production of citrus and almonds decreased, as expected.  The decreases in orange and lemon acreage, however, were more than offset by increased acreage of walnuts and grapes.  The switch of developer and investor interest to walnuts and grapes appears to have added to the cyclical instability of production and prices for these two crops.  Perennial crop adjustments to selective changes in tax provisions involve very significant time lags.

PROFITABILITY OF SITE-SPECIFIC NITROGEN RECOMMENDATIONS FOR MICHIGAN CORN
Provedor de dados: 31
Autores: Liu,   Yanyan.
Site-specific nitrogen application (SSNA) has been considered a potentially more efficient nitrogen (N) management than uniform N application (UNA), because it tailors the N application rate to meet crop needs. However, previous studies on the profitability of SSNA were inconclusive. This study examines the conventional N fertilizer recommendation as a possible reason for the poor profitability of previous SSNA studies. Most previous SSNA experiments followed state-level N recommendations based on yield goals and/or soil nutrient levels that assume corn yield response to N does not vary site-specifically. This study challenges that assumption. It examines a set of six continuous site characteristic variables, more than any previous study, in order to...

VARIABLE-RATE NITROGEN APPLICATION UNDER UNCERTAINTY:  IMPLICATIONS FOR PROFITABILITY AND NITROGEN USE
Provedor de dados: 31
Autores: Isik,   Murat; Khanna,   Madhu.
A micro-level model of farmer decision making is developed to examine the extent to which uncertainty about potential yields influences the value of site-specific technologies.  The economic and environmental benefits of these technologies arise from two sources: information gathering and variable-rate nitrogen application is higher on fields with low average potential yields, high spatial variability, positively skewed potential yield distributions, responsive yield to nitrogen, and low uncertainty.  Variable-rate application decreases nitrogen use by reducing the extent of overapplication.  However, in the presence of uncertainty about potential yields, the incentives to overapply nitrogen irrespective of the method of application, uniform of variable...

Impacts of Inventory Credit, Input Supply Shops and Fertilizer Micro-Dosing in the Drylands of Niger
Provedor de dados: 31
Autores: Pender,   John L.; Abdoulaye,   Tahirou; Ndjeunga,   Jupiter; Gerard,   Bruno; Edward,   Kato.
This study investigates the impacts of access to inventory credit (warrantage), input supply shops, fertilizer micro-dosing demonstrations, and other factors on farmers' use of inorganic and organic fertilizer in Niger, and the impacts on crop yields. We find that access to warrantage and input shops and participation in fertilizer micro-dosing demonstrations have increased use of inorganic fertilizer. Access to off-farm employment and ownership of traction animals also contribute to use of inorganic fertilizer. Use of organic fertilizer is less affected by these factors, but is substantially affected by the household's crop mix, access to the plot, ownership of durable assets, labor and land endowments, and participation in farmers' associations.

Energy Crop Supply in France: A Min-Max Regret Approach
Provedor de dados: 31
Autores: Kazakci,   Akin; Rozakis,   Stelios.
This paper attempts to estimate energy crop supply using an LP model comprising hundreds of representative farms of the arable cropping sector in France. In order to enhance the predictive ability of such a model and to provide an analytical tool useful to policy makers, interval linear programming (ILP) is used to formalise bounded rationality conditions. In the presence of uncertainty related to yields and prices it is assumed that the farmer minimises the distance from optimality once uncertainty resolves introducing an alternative criterion to the classic profit maximisation rationale. Model validation based on observed activity levels suggests that about 40% of the farms adopt the min-max regret criterion. Then energy crop supply curves, generated by...

Horizontal coordination and free-riding in a group of certified organic crop growers: An empirical study of the Ezemvelo Farmers’ Organization in KwaZulu-Natal, South Africa
Provedor de dados: 31
Autores: Gadzikwa,   Lawrence; Lyne,   Michael C.; Hendriks,   Sheryl L.
This study investigated the prevalence and determinants of free-riding in the Ezemvelo Farmers’ Organization (EFO), a group of certified organic crop growers in South Africa, using data gathered in a census survey of its 151 partially and fully certified members. The computed free-riding index scores suggested that free-riding posed a serious threat to the group’s collective marketing efforts. Regression analysis showed that members who were male, poorly educated, aware of loopholes in the grading system, and who did not trust the buyer, were more likely to free-ride. In the longer term, the EFO should address institutionalized free-riding by issuing tradable ownership rights. In the short term, it must engage with the packhouse (buyer) to remove flaws in...

COMPOSED ERROR MODEL FOR INSECT DAMAGE FUCNTIONS: YIELD IMPACT OF ROTATION RESISTANT WESTERN CORN ROOTWORM IN ILLINOIS
Provedor de dados: 31
Autores: Mitchell,   Paul D.; Gray,   Michael E.; Steffey,   Kevin L.
This paper describes a composed error model for estimating the conditional distribution of yield loss to serve as an insect damage function.  The two-part error separates yield variability due to pest damage from other non-pest factors such as soil heterogeneity, non-uniform application of agronomic practices, and measurement errors.  Various common functional forms (linear, quadratic, Cobb-Douglas, negative exponential, hyperbolic, sigmoid) for the pest damage function are presented and parameter estimation is described. As an empirical illustration, the model is used to estimate a damage function for corn rootworm, the most damaging insect pest of corn in the United States.  The estimated damage function gives expected proportional yield loss as a...

Scope economies can be used in studies of farming systems to provide a measure of synergies between different farm enterprises and between activities within farm enterprises. In this paper, they are reported for farms in three benchmarking groups in Australia by estimating stochastic input distance functions and calculating an 'economies of scope parameter'. Evidence of significant scope economies between sheep and crop enterprises, and between beef and crop enterprises, is presented and discussed. Similar evidence is reported between wool and lamb activities and wool and mature sheep trading activities within the sheep enterprise.

Provedor de dados: 31
Autores: Arzac,   Enrique R.
This paper evaluates stabilization policies by applying methods of stochastic control and dynamic analysis to an econometric model of the U.S. grain market. Its main results are: (1) the aggregate consumer and producer surplus generated by the model is insensitive to the choice of the market regime; (2) policies directed to stabilize prices at levels compatible with nondecreasing farm revenue require the management of both grain inventories and domestic supply; (3) price fluctuations are significantly less under optimal stabilization than in the unregulated version of the model; and (4) historical policies have destabilizing effects on the market model.

A magyarországi zöldség- és gyümölcságazat felkészülése az uniós csatlakozásra nem volt igazán eredményes, uniós tagságunk eddigi tapasztalatai, eredményei is felemásak. A csatlakozásnak eddig több a negatív, az ágazat jövőjét veszélyeztető következménye, mint a pozitív hozadéka. A korábbi gyengeségek – alacsony szervezettség, elavult műszaki színvonal, hiányos logisztikai rendszerek, elaprózott birtokstruktúra, szélsőségesen differenciált termelési (gazdálkodási) színvonal – következtében itthon piacvesztés, strukturális feszültségek jöttek létre.

OPTIMAL CONTROL OF PEST RESISTANCE TO TRANSGENIC CROP VARIETIES
Provedor de dados: 31
Autores: Grimsrud,   Kristine M.; Huffaker,   Ray G.
Transgenic corn varieties entered the market in 1996.  These plant varieties carry a gene from the soil bacterium Bacillus thuringiensis kurstaki, Bt, that makes the plant produce a toxin deadly to the pest insect European Corn Borer (ECB) Ostrinia nubilalis (Hübner).  Since ECB may build up genetic resistance to this toxin, the growers of transgenic corn varieties are required to plant a portion of their field (refuge) with regular corn.  This requirement is expected to prolong the efficiency of Bt corn in combating the ECB because some non-resistant pests can survive in the refuge, and thereby dilute the build-up of resistance in the overall pest population.  A fixed refuge size of 20 percent is the currently recommended "rule-of-thumb" by the...

Evaluation of historic, current and future water demand in the Olifants River Catchment, South Africa
Provedor de dados: 31
Autores: McCartney,   Matthew P.; Arranz,   Roberto.
Water resource development has played a significant role in the expansion of agriculture and industry in the Olifants River Catchment. However, currently water deficit is one of the major constraints hampering development in the catchment; both the mining and agricultural sectors are producing below optimal levels because of their reliance on insufficient supplies. In this study, the Water Evaluation and Planning (WEAP) model was used to evaluate scenarios of historic, current and future water demand in the catchment. For each scenario, the WEAP model was used to simulate demand in five different sectors (rural, urban, mining, commercial forestry and irrigation) over a 70-year period of varying rainfall and hydrology. Levels of assured supply were...

How Important is Reputation for New Zealand Wine Makers?
Provedor de dados: 31
Autores: Bicknell,   Kathryn; MacDonald,   Ian.
The wine industry in New Zealand has been maturing over the past few decades, with consumers becoming more sophisticated and wineries responding by increasing their production of premium varieties. In addition, there have been several legal changes and subsequent changes to the distribution and marketing of wine in New Zealand that have made wine more widely available. It is therefore an interesting and dynamic time to gain a more comprehensive understanding of the relative effects of regional reputation and producer-specific quality on the willingness to pay for domestically produced premium table wine in New Zealand. Previous empirical work suggests that New Zealand consumers rely on both expert opinion and regional reputation when determining their...

This study examines the impact of stochastic harvest field time, corn cob and stover harvest technologies, increases in farm size, and alternative tillage practices on profit maximizing potential of corn cob and stover collection in North Dakota. Using three mathematical programming models, we analyze farmers’ harvest activities under 1) corn grain only harvest option, 2) simultaneous corn grain and cob harvest(one-pass)  option 3) separate corn grain and stover harvest (two-pass) option. Under the first corn grain only option, farmers are able to complete harvesting corn grain and achieve maximum net income in a fairly short amount of time with existing combine technology. However, under the simultaneous corn grain and cob one-pass harvest option, our...

FACTORS AFFECTING FRESH POTATO PRICE IN SELECTED TERMINAL MARKETS
Provedor de dados: 31
Autores: Goodwin,   Harold L., Jr.; Fuller,   Stephen W.; Capps,   Oral, Jr.; Asgill,   Oladimagi W.
Monthly, quarterly, and annual cross-sectional and time-series data for the period 1982-85 were analyzed to identify factors affecting terminal market price for four types of fresh potatoes. Results indicated that state of origin, terminal market package type, and season of marketing were significant quality variables affecting price. Price differences among potato types because of season of marketing and stocks of fall potatoes were evident. These results suggest that cultivar selection, cultural practices, planting and harvesting schedules, packaging, and market selection – factors which are ultimately controlled by growers and grower/shippers – can be utilized effectively as mechanisms to increase price and expand markets.

Determinants of Profit Efficiency Among Small Scale Rice Farmers in Nigeria: A Profit Function Approach
Provedor de dados: 31
Autores: Kolawole,   Ogundari.
This study employs a stochastic frontier approach to examine profit efficiency of small scale rice farmers in Nigeria using farm-level survey data collected from 200 farmers in the study area. Data were analysed using descriptive statistics and standard profit function. The result shows that about 60 percent of potential profit is gain due to production efficiency while the remaining can be attributed to both technical and allocative inefficiencies in the study area. Also, the result further revealed that age, educational level, farming experience and household size positively affected profit efficiency. These variables are thus important in policy formulation by government.

Water Saving Technology in Chinese Rice Production - Evidence from Survey Data
Provedor de dados: 31
Autores: Abdulai,   Awudu; Glauben,   Thomas; Herzfeld,   Thomas; Zhou,   Shudong.
Whereas water is an important input in rice production, China faces severe problems with increasing demand for water and limited water resources. In conventional paddy production, one of the most important irrigated crops, a significant amount of irrigation water is lost due to percolation and evaporation. Therefore, it exist a vivid research in water saving rice technologies. This paper analyzes the adoption of one of these water-saving rice production technologies, the so-called Ground Cover Rice Production System (GCRPS), in the Hubei province. Based on farm survey data several factors which affect the adoption decision could be identified. The adoption decision is treated as a binary choice problem and therefore a probit model is used for the...

Autores: Mather,   David; Bernsten,   Richard H.; Rosas,   Juan Carlos; Ruano,   Abelardo Viana; Escoto,   Danilo; Martinez,   Julio.
Since the mid-1980s, bean research in Honduras has focused on the development of improved varieties resistant to key diseases, principally Bean Golden Yellow Mosaic Virus (BGYMV), one of the main constraints to bean production in the country. This paper presents evidence of recent adoption rates of improved bean varieties, the farm-level economic impact of adoption, and the ex post rate of return to bean research in Honduras from 1982-2010.   Results from a 2001 farm-level survey in the two principal bean-producing regions in Honduras show that 46 to 51% of bean farmers (depending upon the season) have adopted an improved variety, and that adoption is scale-neutral with respect to farm-size and market orientation.  Due to the potential problem of sample...

Regime shifts and technology diffusion in crop yield growth paths with an application to maize yields in Zimbabwe
Provedor de dados: 31
Autores: Myers,   Robert J.; Jayne,   Thomas S.
An alternative specification for the trend component of crop yield growth is developed and applied to maize yield data for Zimbabwe’s large‐scale farming sector. This accounts for permanent regime shifts as new technologies are discovered but allows gradual absorption as adoption follows a diffusion path. Econometric methods are used to estimate the timing and importance of innovations, as well as the length of the diffusion path. Results from an application to Zimbabwe commercial maize yields indicate two major regime shifts that can be associated with the introduction of hybrid seed varieties, and a diffusion path that extends over a decade.

Most of the supply elasticity estimates reported for Australian agriculture are derived from equations estimated using time series data and incorporating ad hoc assumptions about price expectations. The authors' aim is to compare previously obtained supply elasticity estimates with those derived using theoretically more acceptable survey data on both producers' intentions and price expectations. Surveys were conducted in three regions in N.S.W., namely, the Southern Tablelands, the South-West Slopes and a portion of the Western Division centred on Cobar .

Rapid increases in input prices have cast a large shadow over the enthusiasm created by higher product prices. In this paper we forecast the trends in input prices and use these trends to forecast production costs for corn, soybeans, and wheat at the national level, and for regions within the U.S. Although the Heartland is forecast to maintain its competitive edge in corn costs, the Northern Great Plains and Prairie Gateway regions are forecast to increase their competitive advantage due to using less fertilizer and chemicals on average which results in relative costs decreasing for these regions. For soybeans, the Heartland is forecast to maintain its competitive edge although the Eastern Uplands region was forecast to increase its competitive advantage...

Agriculture is the most significant contributor to Ethiopia’s economy. Most of the agricultural production is under rainfed conditions and thus extremely sensitive to rainfall variability. Irrigation development, including smallholder irrigation, is used by the Ethiopian Government to attempt to mitigate the effects of rainfall variability. In this study, we look at smallholder irrigation - modern and traditional irrigation systems. A detailed description of the cropping patterns is given. The stochastic frontier production function approach is used to estimate technical inefficiency, and constraints to production are analyzed. Since the traditional system is found to be efficient but on a lower production frontier, the study shows that significant gains...

Genetically modified cotton varieties have greater production efficiency for smallholders in farming communities in China. We also find that the adoption of Bacillus thuringiensis (Bt) cotton varieties leads to a significant decrease in the use of pesticides. Hence, we demonstrate that Bt cotton appears to be an agricultural technology that improves both production efficiency and the environment. In terms of policies, our findings suggest that the government should investigate whether or not they should make additional investments to spread Bt to other cotton regions and to other crops.

Does Adoption of Improved Maize Varieties Reduce Poverty? Evidence from Kenya
Provedor de dados: 31
Autores: Mwangi,   Wilfred; Mwabu,   Germano; Nyangito,   Hezron Omare.
Adoption of technologies that increase farm yields is a prerequisite for poverty alleviation in agrarian societies. However, the link between adoption of improved agricultural technologies and poverty reduction is not well understood or documented. This relationship is explored with an example of improved maize seed adoption in Laikipia and Suba - two rural districts in Kenya. We show that adopters of improved maize varieties have higher yields per acre and that poverty is negatively correlated with technology adoption. Policies for increasing diffusion of these technologies include improving access roads to market centers to enhance maize profitability and extension of information about improved maize varieties to farmers.

Using the economic surplus approach, we estimate the economic benefits of U.S. research and outreach for integrated pest management (IPM) of soybean aphid. We calculate ex ante net benefits from adoption of an IPM action threshold (AT). The AT triggers insecticide application only if the value of predicted yield damage from pest scouting is expected to exceed the cost of pest control. Our research finds that gradual adoption of AT-based IPM over the 15 years since soybean aphid IPM research began in 2003 generates a projected economic net benefit of $1.3 billion, for an internal rate of return of 140%....

Hybrid Rice Production Possibilities in the Southern Rice Producing Region
Provedor de dados: 31
Autores: Deliberto,   Michael A.; Salassi,   Michael E.
Hybrid rice represents a new and increasing popular variety option for rice producers. This study examines the acreage diversification among long grain rice varieties in the southern rice region and presents estimates of thedifferences in expected costs and returns among the production of conventional, Clearfield®, and hybrid rice varieties. Breakeven yield increases required to cover additional hybrid rice production costs are estimated over a range of rough rice market prices for both owner and tenant rental situations. Rough rice market price adjustments resulting from grade differences from milling yields are also discussed.

Autores: Aakre,   Dwight G.; Haugen,   Ronald H.; Swenson,   Andrew L.
The National Corn Growers Association Public Policy Team’s Base Revenue Projection Program (BRP) and the Revenue Countercyclical Program (RCCP) were analyzed. The analysis was done for soybeans using the BRP-RCCP calculator, as developed by the National Corn Growers Association. Three representative counties (Cass, Stutsman and Benson) were chosen in North Dakota. Historic and projected data were used to analyze 2002 to 2010 crop years. A comparison of the BRP-RCCP programs to the current farm program was done.  From 2002 to 2005, all counties would have received more payments with the BRP-RCCP program than they would have received under the current farm program. Benson County would benefit the most from this program, receiving $58.56 per acre more during...

Autores: Ferrer,   Stuart R.D.; Hoag,   Dana L.; Nieuwoudt,   W. Lieb.
A direct elicitation of utility approach is used to measure risk preferences of commercial sugar cane farmers in the Mzimkulu, Sezela and Eston sugarmill areas of KwaZulu-Natal. Arrow- Pratt absolute risk aversion coefficients are elicited, adjusted for both range and scale of the data, to allow both inter and intra study comparisons of risk preferences. Of 53 farmers surveyed, two refused to participate in lottery games for religious or moral reasons. Of the remainder 57.2 percent were risk averse, 29.6 percent risk neutral and 13.2 percent risk preferring. On average they were risk averse although risk preferences vary significantly amongst individuals. Regression analysis indicates that on average sugar cane farmers are averse to a possible loss in...

PLANT NUTRIENT DEMAND FUNCTIONS FOR TENNESSEE WITH PRICES OF JOINTLY APPLIED NUTRIENTS
Provedor de dados: 31
Autores: Roberts,   Roland K.
Several studies have estimated plant nutrient demand functions for nitrogen, phosphate, and potash. All included own-price effects but excluded prices of jointly applied nutrients. In this study, nutrient demand functions, which include prices of all three nutrients, are estimated for Tennessee by seemingly unrelated regression. Results suggest that cross-price effects are important in determining plant nutrient demand, at least in the case of Tennessee, and that multicollinearity need not be a hindrance in all cases to including cross-price effects in plant nutrient demand models.

This paper investigates the respective roles of spatial integration and arbitrage costs in explaining the adjustment of local prices to policy changes using the example of Ghana. We introduce a model of price formation and market integration that incorporates the price transmission process between local and central markets and also captures the implications for volatility of local prices. We explore the implications of the model for the time-path of price adjustments, as determined directly and indirectly through the marketing sector. We show that the price-adjustment process in a local market is determined by the degree of interdependence between that market and the central market in which price-shock originates, and estimate the intertemporal and...

Autores: Welsch,   Delane E.; Stuthman,   Deon; Showman,   Alan.
A mail survey was conducted in 1977 of farmers who were thought to be oats producers, using names obtained from several lists. The purpose of the 1977 mail survey was to obtain answers to the following questions: (1) What kind of farmer grows oats, (2) Where does he grow them, (3)Why does he grow them, (4) How does he produce them? Answers to these questions should enable the breeding program and the Extension Program at the University of Minnesota to better address the problems of oat production and thus maintain, or hopefully improve the relative competitive ability of oats as a crop in Minnesota.

Autores: Gomez,   Sonia Quiroga; Iglesias,   Ana.
The goal of this paper is to increase the capacity of the agriculture sector to understand and respond to the climate variability, by reducing the uncertainty of the farmers over decisions that are affected for meteorological conditions. To study the yield responses to meteorological variables in the past is crucial to understand the vulnerability of the agriculture to the climate change in the future. We have estimated regression models where the historical yields have been put in dependence of variables that can represent main drivers of global change, such as climate variables and technological ones. In this context we evaluate its influence over the yields. Among the conclusions we find that the adaptation to climate change requires challenges in which...

CONTRACT MARKETING IN THE US AFTER THE 2002 FARM ACT: THE CASE OF PEANUTS

Autores: Revoredo-Giha,   Cesar; Nadolnyak,   Denis A.; Fletcher,   Stanley M.
The elimination of the marketing quota system that regulated the peanut market since the 1930s has been accompanied by the emergence of marketing contracts between farmers and peanut buyers (mainly peanut shellers). Two types of contracts have been observed, forward contracts for delivery at harvest or at a later date and “option to purchase” contracts. We analyze the clauses of contracts used by major shellers in order to infer the motivation behind these contracts (i.e., risk sharing, reduction of transaction costs, improve coordination, exercise of market power, etc.). The analysis points out that the main role of the contracts is to replace the marketing structure existing prior the 2002 Farm Act, where peanut marketing was quite regulated. In this...

The impact of China's new rural income support policy and recent price trends on grain production and rural income inequality is assessed for two villages with different degrees of market access in Northeast Jiangxi Province. Two village-level general equilibrium models are used to analyze household decision making and interactions between households within these villages. Parameter estimation and model calibration is based on data collected during an extensive survey held in these villages in the year 2000. The household classification used in these models allows us to draw conclusions that are relevant for many other villages and regions in China. Simulation results show that the income support policy does not reach its goal of promoting grain...

The family farm in a globalizing world: The role of crop science in alleviating poverty
Provedor de dados: 31
Autores: Lipton,   Michael.
The topic of family farms has been gaining prominence in the academic, policy, and donor communities in recent years. Small farms dominate the agricultural landscape in the developing world, providing the largest source of employment and income to the rural poor, yet smallholders remain highly susceptible to poverty and hunger. With the advance of globalization and greater integration of agricultural markets, the need for increases in agricultural productivity for family farms is particularly pressing. Raising productivity and output of small farmers would not only increase their incomes and food security, but also stimulate the rest of the economy and contribute to broad-based food security and poverty alleviation. In this paper, Michael Lipton builds an...

Autores: Sennoga,   Edward B.; Matovu,   John Mary; Twimukye,   Evarist P.
Uganda still lags behind in its tax collections at the domestic level. For most of the commodities the tax collection effort is not more than 5 percent relative to the statutory rate of 18 percent. This results into a situation where the government has to rely a lot on foreign financing. From the analysis, there is a lot of improvement where URA can be able to increase its tax effort. this could be achieved by targeting commodities that are under-taxed and excluding food items for equity purposes. Increasing domestic collection would also result into less over reliance on taxing a few commodities especially fuel which is interlinked with a lot of other sectors and could indeed harm growth in the long-run. We also find that the tax effort on imports is...

Agriculture is the foundation of the Manawatu/Wanganui region’s economy, which consists of 300,000 ha of highly erodible land. Past land management practices caused a major threat to the long-term sustainability of the region. Horizons Regional Council introduced Whole Farm Plans (WFP) as part of a variety of tools to protect and conserve the land. This paper discusses the progressive findings of a study about farmers’ WFP adoption decisions. Following Gladwin’s (1989) ethnographic decision tree modeling (EDTM) approach, qualitative interviews were held with a sample of 15 WFP adopters and 14 non-adopters across the Region to develop the adoption decision tree. Key findings were that hill country farmers’ decision to develop, or not develop, a WFP was...

This chapter discusses the implementation challenges of the WHO Guidelines on safe wastewater use pertaining to the adoption of the so-called ‘post-treatment’ or ‘non-treatment’ options, like safer irrigation practices or appropriate vegetablewashing in kitchens. Due to limited risk awareness and immediate benefits of wastewater irrigation, it is unlikely that a broad adoption of recommended practices will automatically follow revised policies or any educational campaign and training. Most of the recommended practices do not only require behaviourchange but might also increase operational costs. In such a situation, significant efforts are required to explore how conventional and/or social marketing can support the desired behaviour-change towards the...

Forecasting World Crop Yields as Probability Distributions
Provedor de dados: 31
Autores: Ferris,   John N.
Traditionally, agricultural forecasts, whether for the coming year or several years into the future, have been based on assumptions of normal weather and trend crop yields. That weather is seldom normal and that yields seldom fit trends are well recognized. However, relatively little attention has been given to projecting crop yields stochastically even though computer capacity and software programs are available to do so. One reason is that the task is more challenging than to assign standard deviations to various crop yields and simulate normal distributions using random number generators. For one, deviations of crop yields from trends may be correlated especially if the locations of the crops overlap such as is the case with US corn and soybeans. To...

Cropping Structures Adjustments Under Water Limitations in the Egyptian Agriculture
Provedor de dados: 31
Autores: Abdou,   Amin I.
Using programming methods, the two models of cropping structures suggested by the study were remarkably different. The first model considered water availability levels, while the second tried to optimize its use. As such, some cash crops were excluded from the second model as water extensive users, such as some kinds of fruits. Hence, the second type models expected net revenues and benefit-cost ratios dropped to nearly one-third the corresponding estimates of the first type, and about 10-20% higher than those of the actual cropping structures in average. Accordingly, encouraging farmers to adopt cropping patterns of rational water use would be in vain unless fortified by taxation tools and guidance toward efficient methods of cost reduction and/or yields...

Autores: Latruffe,   Laure; Desjeux,   Yann; Fogarasi,   Jozsef; Bakucs,   Lajos Zoltan; Ferto,   Imre.
Pig farming is one of the strongest polluters of water resources due to its intensive production techniques and slurry rejection. Several European countries have already introduced environmental regulations aiming at reducing the pollution caused by nitrates from agricultural sources, but not yet Hungary. This paper investigates how Hungarian pig farms would be affected if such regulations are to be enforced. We calculate farm technical efficiency separately for two types of pig production systems – namely farrowing only and farrow-to-finish farms (FAFI farms) and finishing only farms (FI farms) – using 2001 data on pig activity and Data Envelopment Analysis (DEA). We then investigate whether environmental regulations would affect the farms’ technical...

ADOPTION OF BIOENGINEERED CROPS
Provedor de dados: 31
Autores: Fernandez-Cornejo,   Jorge; McBride,   William D.
Use of crop biotechnology products, such as genetically engineered (GE) crops with input traits for pest management, has risen dramatically since commercial approval in the mid-1990s. This report addresses several of the economic dimensions regarding farmer adoption of bioengineered crops, including herbicidetolerant and insect-resistant varieties. In particular, the report examines: (1) the extent of adoption of bioengineered crops, their diffusion path, and expected adoption rates over the next few years; (2) factors affecting the adoption of bioengineered crops; and (3) farm-level impacts of the adoption of bioengineered crops. Data used in the analysis are mostly from USDA surveys.

Local Seed Systems and Village-Level Determinants of Millet Crop Diversity in Marginal Environments of India
Provedor de dados: 31
Autores: Nagarajan,   Latha; Smale,   Melinda.
In the subsistence-oriented, semi-arid production systems of Andhra Pradesh and Karnataka, India, the environment is marginal for crop growth and often there is no substitute for millet crops. Across communities, farmers grow thirteen different combinations of pearl millet, sorghum, finger millet, little millet, and foxtail millet varieties, but individual farmers grow an average of only two to three millet varieties per season. The notion of the seed system includes all channels through which farmers acquire genetic materials, outside or in interaction with the commercial seed industry. Data are compiled through household surveys and interviews with traders and dealers in village and district markets. Based on the concept of the seed lot, several...

EFFECT OF PROPOSED GRAIN STANDARDS ON MARKETING COSTS OF THE U.S. SORGHUM SECTOR: AN INTERREGIONAL TRANSSHIPMENT-PLANT LOCATION MODEL
Provedor de dados: 31
Autores: Ziari,   Houshmand A.; Fuller,   Stephen W.; Grant,   Warren R.; Sutaria,   Vinod.
Recent legislative initiatives call for studies to evaluate costs associated with cleaning U.S. grains to meet more stringent standards. This paper reports on a study which developed a mixed-integer programming model of the U.S. sorghum sector to (1) determine the least-cost geographic location for new cleaning investment at the country, terminal and port elevator stages of the marketing system and (2) measure additional system marketing costs associated with implementing the proposed standards. Results show the least-cost cleaning location to be at country and terminal elevators in excess supply regions. Implementing the proposed standard would increase system costs about 2 percent.

Autores: Badstue,   Lone B.; Bellon,   Mauricio R.; Berthaud,   Julien; Ramirez,   Alejandro; Flores,   Dagoberto; Juarez,   Xochitl; Ramirez,   Fabiola.
This project explored the possible role of collective action among small-scale farmers in managing and maintaining genetic resources in a center of crop diversity. It focused on the local institutions that ensure the supply of seed of diverse maize landraces to small-scale farmers in the Central Valleys of Oaxaca, Mexico. The key hypothesis was that the medium-to-long-term supply of a diverse set of varieties to any individual smallscale maize farmer depends on an agreement among a group of farmers to manage and supply the seed of these landraces to each other, if the need arises, and that this constitutes a form of collective action. Six communities were studied, three of them indepth. Methodologies used included in-depth semi-structured interviews with...

2011 Outlook of the U.S. and World Corn and Soybean Industries, 2010-2020
Provedor de dados: 31
Autores: Taylor,   Richard D.; Koo,   Won W.
This report evaluates the United States and world corn and soybean markets for the 2010-2020 period using the Global Corn and Soybean Policy Simulation Model. This analysis is based on a series of assumptions about general economic conditions, agricultural policies, weather conditions, and technological change. Corn-based ethanol production has influenced United States corn industry. As long as the production of corn-based ethanol remains strong, corn prices will likely remain at a level higher than the long term average. However, changes in the U.S. Federal government subsidies or mandates could significantly impact the world corn market. Under the current assumptions in the model, corn price is expected to remain in a range between $4.68 and $5.35 per...

COSTS AND RISKS OF TESTING AND SEGREGATING GM WHEAT
Provedor de dados: 31
Autores: Wilson,   William W.; Dahl,   Bruce L.
Development of genetically modified crops is challenging the functions of the grain marketing system with many participants arguing for Identity Preservation systems prior to release of GM varieties.  In this study, a stochastic optimization model was developed to determine optimal testing strategies.  The model chooses the optimal testing strategy that maximizes utility (minimizes disutility) of additional system costs due to testing and rejection and allows estimation of the risk premium required for sellers to undertake a dual marketing system with GM/Non-GM segregations over the current Non-GM system.  Elements of costs (testing costs, rejection costs, and risk premium) were estimated for a base model representing a grain export chain.  The model...

Effect of Liberalization on Institutional Agricultural Credit Flow and its Relationship with Average Cost of Cultivation in Indian Agriculture
Provedor de dados: 31
Autores: Khan,   A.R.; Tewari,   S.K.; Shukla,   A.N.
This paper has examined (i) the nature and extent of inter-state disparities in per hectare flow of short-term institutional credit to agriculture, and (ii) its relationship with average cost of cultivation across states. It has covered all the six regions of the country comprising seventeen agriculturally most important states having about 96 per cent agricultural land in the country. It has revealed that inter-regional disparities in per hectare flow of institutional credit as measured through coefficient of variation (CV) had increased during the pre-liberalization period between 1980-81 and 1990-91. During the post-liberalization era (1991-92 to 2001-02), the inter-regional disparities have reduced. The per hectare institutional credit flow has shown...

Provedor de dados: 31
Autores: Camarena-Gomez,   Dena M.; Sanjuan,   Ana Isabel.
Stated consumer preferences for walnuts in Spain are investigated by means of a choice experiment. Conditional heterogeneity is explored, assuming two possible sources: how often walnuts are consumed and how driven by health and nutrition attitudes or convenience the consumer is. In particular, the possibilities for a mostly unknown variety in the Spanish market are investigated. Specific guidelines for the distribution and commercialisation of walnuts are provided.

Spatial and Temporal On-Farm Risk Management - Crop Production Scheduling and Index Insurance Strategies
Provedor de dados: 31
Autores: Lin,   Shanshan; Mullen,   Jeffrey D.; Hoogenboom,   Gerrit.
An agronomic crop growth model, Decision Support System for Agro-Technology Transfer (DSSAT), is used to find optimal crop management strategies for cotton production in Mitchell, Miller, and Lee Counties in Georgia during the past 10 years. Planting date and irrigation threshold are the two variables optimized to maximize farmer's expected utility. A decreasing absolute risk aversion - constant relative risk aversion (DARA-CRRA) utility function is used to examine crop management decision that can be influenced by changes in inter-temporal risk behavior. Comparison is made from management perspective - one is dynamic crop management strategy that varies each year; one is static (constant) strategy over 10 years. Based on the best crop management...

This report is a summary of five years of grape costs and returns data collected from Lake Erie Region grape growers for the 2001-2005 seasons. “Concord” and “Niagara” grapes utilized for juice and generic wine accounted for over 90 percent of the survey acreage. About two-thirds of the acreage surveyed was in New York and one-third from Pennsylvania. In recent years, 42 to 49 growers participated, with total vineyard acreage ranging from about 4,400 to 5,200 acres. Average costs per acre over the entire five year period were $1,663, including an imputed value for the operator’s labor. Major cost categories were paid labor ($380 per acre), depreciation ($213), interest ($114), operator labor ($116) and chemicals ($117). Average yield per farm was 6.4 tons...

Varieties, Attributes and Marketed Surplus of a Subsistence Crop: Bananas in Uganda
Provedor de dados: 31
Autores: Edmeades,   Svetlana.
In this paper, the heterogeneity of crops is recognized and food commodities are disaggregated into varieties of a crop in order to test whether variety attributes influence the size of the marketed surpluses of selling households. The behavior of semi-subsistence banana producing households in Uganda is examined using farm-level survey data collected in 2003. Bananas, the staple crop of the country, are important for meeting immediate consumption requirements and for income generation. The relationship between marketed surpluses and variety attributes is defined theoretically and tested empirically using a semi-parametric censored quantile regression. Inferences are made in two stages to account for differences in the structure of decision-making....

Technology adoption in precision agriculture has received considerable attention, while abandonment has received little. Our objective was to identify factors motivating adoption and abandonment of precision soil sampling in cotton. Results indicate younger producers who farmed more cotton area, owned more of their cropland, planted more non-cotton area, used a computer, or used a Personal Digital Assistant (PDA) were more likely to adopt precision soil sampling. Those with more cotton area or who owned livestock were more likely to abandon, while those who used precision soil sampling longer, used a PDA, or used variable-rate fertilizer application were less likely to abandon.

Partial Reform of World Rice Trade: Implications for the U.S. Rice Sector
Provedor de dados: 31
Autores: Haley,   Stephen L.
This paper analyzes the consequences for the United States of a partial reform of world rice trade. It is argued that likely trade reform would occur in the japonica rice producing countries of Japan, South Korea, Taiwan, and the European Community. Multilateral rice trade liberalization would have strong effects for medium grain rice in the United States. The strength of these effects might not be felt for a couple of years after the liberalization has begun because of minimal Japanese imports in the first couple of years of liberalization. U.S. rice millers will likely benefit more than producers. California producers would be the major beneficiaries of more open world rice markets.

Analyzing the Effects of Weather and Biotechnology Adoption on Corn Yields and Crop Insurance Performance in the U.S. Corn Belt
Provedor de dados: 31
Autores: Vado,   Ligia; Goodwin,   Barry K.
Favorable weather and the adoption of Genetically Modified (GM) corn hybrids are often argued to be factors that explain recent corn yield increases and risk reduction in the U.S. Corn Belt. The focus of this analysis is to determine whether favorable weather is the main factor explaining increased and more stable yields or if biotechnology adoption is the more relevant driving force. The hypothesis that recent biotechnology advances have increased yields and reduced risks by making corn more resistant to pests, pesticides, and/or drought is tested. Fixed effects models of yields and crop insurance losses as functions of weather variables and genetically modified corn adoption rates are estimated taking into account the non-linear agronomic response of...

Maize and wheat production trends in South Africa in a deregulated environment
Provedor de dados: 31
Autores: Breitenbach,   Marthinus C.; Fenyes,   Tamas I.
Qualitative control measures and government regulation of the marketing of agricultural produce was seen as distorting the working of the market mechanism. Trade liberalisation, with tariffication of agricultural produce and the deregulation of the marketing of agricultural produce was therefore promoted. It was expected that producers of agricultural produce would respond to liberalisation efforts and deregulation in a way that would move production closer to some optimum point. An analysis of production trends for maize and wheat confirms that production of these commodities have moved closer to an optimum point, especially after the deregulation of these markets.

The objective of this paper is to improve our knowledge of how the traditional goals of income and risk reduction may affect farmers' choice of production methods especially those that are more environmentally sensitive.  The distribution of net cash flows for alternative crop production methods or strategies were estimated. These distributions were compared to predict whether the traditional goals of income level and risk avoidance will be at odds with environmental goals or whether farmers can find production strategies that support both types of goals.  Previous studies have used average yields and conditions to find that alternative tillage systems have lower costs that conventional systems (e.g., Smolik, Dobbs, and Rickerl; Weersink et al.)

Autores: Schonhart,   Martin; Schauppenlehner,   Thomas; Schmid,   Erwin.
Integrated land use models (ILM) are increasingly applied tools for the joint assessment of complex economic-environmental farming system interactions. We present an ILM that consists of the crop rotation model CropRota, the bio-physical process model EPIC, and the farm optimization model FAMOS[space]. The ILM is applied to analyze agri-environmental measures to maintain biodiversity in an Austrian landscape. We jointly consider the biodiversity effects of land use intensity (i.e. nitrogen application rates and mowing frequencies) and landscape development (e.g. provision of landscape elements) using a rich indicator set and region specific species-area relationships. The cost-effectiveness of agri-environmental measures in attaining alternative...

IMPLICATIONS OF REMOTE SENSING IMAGERY AND CROP ROTATION FOR NITROGEN MANAGEMENT IN SUGAR BEET PRODUCTION
Provedor de dados: 31
Autores: Ali,   Mir B.; McBride,   William D.; Daberkow,   Stan G.
Adoption of new technologies, such as remote sensing, is slowed by such factors as high monetary and/or human capital costs and uncertainty about their value.  This analysis explores the impact on nitrogen fertilizer use and efficiency and net returns among sugar beet producers in the Red River Valley from using remote sensing technologies and crop rotation for nitrogen management.  The study found that cropping patterns had a significant impact on nitrogen use and net returns, but that most decision tools used for nitrogen management had little influence.  The impact of using remotely sensed images for nitrogen management in sugar beets was not statistically significant.

Strategic marketing issues and challenges face maize seed marketing firms as farmers increasingly adopt hybrid varieties in a modernizing third world country such as Uganda. The maize seed industry of Uganda has changed dramatically from a government owned, controlled, and operated industry to a competitive market oriented industry with substantial private firm investment and participation. The new maize seed industry is young, dynamic, growing and very competitive. The small maize seed market is already crowded with six firms and the possibility of new entrants including more foreign firms. Maize seed firms must develop a marketing plan (marketing strategy and the 4Ps of product, price, place, and promotion) to analyze what each firm can do to improve...

Economic Impact of Fusarium Head Blight in Malting Barley: Blending Margins and Firm-Level Risk
Provedor de dados: 31
Autores: Nganje,   William E.; Johnson,   D. Demcey.
FHB and DON present significant challenges to producers, grain elevators, and the brewing industry. Yield reductions and price discounts incurred by producers in North Dakota, Minnesota, and South Dakota averaged about $45.3 million annually during the years 1998 through 2000. Losses are more substantial when secondary economic impacts are considered. For every $1 of scab losses incurred by the producer, $2 in losses are incurred in other areas of rural and state economies. One way of mitigating these losses is to blend barley with DON and barley without DON. Results from the grain blending model show a sharp decline of DON discounts and losses after blending. The average discount fell from $0.57/bu to $0.17/bu in 1998, $0.48/bu to $0.14/bu in 1999, and...

The acceptance of the NAFTA and GATT trade agreements will impact the U.S. peanut industry. This paper examines trade distorting policies and evaluates the effects of trade liberalization on peanut producers, shellers, manufactures, and U.S. consumers of peanut products. Decreasing marketing quotas and support prices are expected to reduce gross income peanut farmers, revenues to local governments, and tax bases in rural communities. Reduced peanut production would impact buyers/shellers through greater price variability and risk, changes in marketing methods and contractual relationships, and increased emphasis on buying high quality peanuts. Manufactures will have additional sources for peanut supplies. Consumers’ savings from decreases in raw peanuts...

TRANSGÊNICO OU CONVENCIONAL: O DILEMA DA SOJA NO MATO GROSSO
Provedor de dados: 31
Autores: Leitao,   Fabricio Oliveira; Villar,   Patricio Mendez del; Ferreira,   Carlos Magri; Medeiros,   Josemar Xavier De; Carvalho,   Jose Marcio.
O presente artigo procura mostrar quais são os fatores que levam os produtores rurais de Mato Grosso a plantar a soja transgênica em detrimento da convencional, uma vez que a adoção da soja RR traz mudanças na governança dos produtores dentro dessa cadeia. Apesar de haver indícios de que a soja transgênica vai dominar o mercado nacional, é importante saber se isso já está sendo consolidado em Mato Grosso, pois esse é um dos mais representativos no plantio de soja do Brasil, sendo a região de Sorriso a maior produtora mundial em área dessa commoditie. Como aporte teórico para dar sustentação ao trabalho, utilizou-se a Economia dos Custos de Transação (ECT). Diante dos resultados encontrados junto a alguns produtores de Mato Grosso, pode-se inferir que a...

Regional economic impacts of a plant disease incursion using a general equilibrium approach
Provedor de dados: 31
Autores: Wittwer,   Glyn; McKirdy,   Simon; Wilson,   Ryan.
The present study uses a dynamic multiregional computable general equilibrium (CGE) model to estimate the micro- andmacroeconomic effects of a hypothetical disease or pest outbreak. Our example is a Karnal bunt incursion in wheat in Western Australia. The extent of the incursion, the impact of the disease or pest on plant yields, the response of buyers, the costs of eradication and the time path of the scenario contribute to outcomes at the industry, regional, state and national levels. We decompose the contribution of these individual direct effects to the overall impact of the incursion. This might provide some guidance regarding areas for priority in attempting to eradicate or minimise the impacts of a disease or pest. The study also introduces a theory...

DEMAND RELATIONS OF OILSEED PRODUCTS IN SOUTH AFRICA
Provedor de dados: 31
Autores: van Schalkwyk,   Hendrik P.
In this study demand relations for primary oilseeds in South Africa is estimated and interpreted with the use of econometric models. Two different models, namely the Linear Approximate Almost Ideal Demand System (LA/AIDS) and the two-step Error Correction Model (ECM), were applied to annual oilseed data for the years 1971-2002.  The F ratio test for separability failed to reject the null hypothesis of weak separability in most cases, indicating that sunflower seed, soybeans, groundnuts and cotton could be included in the same system and modeled together.  The Hausman test for exogeneity was conducted and proved that the expenditure variable included in the estimated equations is indeed exogenous. The exogeneity of the expenditure variable provides...

RECENT CHANGES IN MARKETING AND TRADE PRACTICES IN THE U.S. LETTUCE AND FRESH-CUT VEGETABLE INDUSTRIES
Provedor de dados: 31
Autores: Handy,   Charles R.; Thompson,   Gary D.; Glaser,   Lewrene K.
Fifteen lettuce and bagged salad shippers were interviewed as part of a larger study on changes in produce marketing. Retail consolidation, changes in technology, and increased consumer demand for convenience, product diversity, and year-round availability have all influenced shipper-retailer relations. The interviewed firms provided more fees and services to retail buyers in 1999 than 1994. Most of the bagged salad shippers paid slotting fees, while none of the lettuce shippers were currently doing so. Bagged salad firms tended to offer services to their customers, while lettuce firms generally complied with the service requests made by retailers.

Financing agricultural inputs in Northern Togo through an inventory credit system: an economic analysis of institutional response
Provedor de dados: 31
Autores: Konlambigue,   Abdou.
Agricultural intensification is widely seen as a condition sine-qua-non for enhanced food security and as a major driver for overall economic growth in sub-Saharan Africa (SSA). In this process, the financial system has an important role to play, especially to finance agricultural inputs. However in SSA, the financial institutions initiated by governments and donors have in general not lived up to the expectations, in particular not for the agricultural sector, because of inappropriate design and weaknesses in implementation. Even the microfinance institutions which were supposed to support the small-scale farmers have deflected for their goals due to the risks that the agricultural sector represents. To date, the economic research tends to concentrate on...

Analyzing the Economics Values of An Alternative Preprocessing Facility in the Biomass Feedstocks - Biorefinery Supply Chain
Provedor de dados: 31
Autores: Yu,   Tun-Hsiang (Edward); Larson,   James A.; Gao,   Yuan; English,   Burton C.
It is generally believed that preprocessing procedure can reduce the transportation and storage costs of biomass feedstock for biofuel production by condensing the feedstock’s size. However, the capital costs of preprocessing facilities could be significant in the feedstock logistics system. Applying a GIS and mixed-integer mathematical programming model, this study evaluates the economic values of a preprocessing technology, stretch‐wrap baling, in the biomass feedstock supply chain for a potential commercial-scale switchgrass biorefinery in East Tennessee. Preliminary results suggest that the stretch-wrap baling equipment outperforms the conventional hay harvest methods in terms of total delivered costs. Although the densification process involves...

With the possible exception of nuclear technology, few scientific breakthroughs have generated the level of emotive debate that has surrounded the roll-out of agricultural biotechnology. Initial discussion about the environmental impacts of agricultural genetic modification, are now frequently juxtaposed with counter-claims that the technologies could actually be part of a wider global environmental solution in relation to climate change mitigation and food shortages. This study tests whether there are any consistent messages on why some countries seem to be advancing adoption of the technology, while others are not. We consider the range of claims in existing literature on adoption tendencies and then use structural equation modelling to test and estimate...

The Role of Coordination and Cooperation for Bt-maize cultivation in Brandenburg, Germany
Provedor de dados: 31
Autores: Consmuller,   Nicola; Beckmann,   Volker; Schleyer,   Christian.
Since 2006, several varieties of transgenic Bt-maize are approved for commercial cultivation in Germany. The German regulatory framework for growing these crops comprises ex-ante regulations as well as ex-post liability rules to protect conventional and organic farming from possible negative side effects of transgenic plants and to ensure co-existence. Public regulation is also suspected to impose additional costs to those farmers who intend to plant Bt-maize. We address the question how Bt-maize growing farmers perceive the additional costs of regulation and whether coordination or cooperation takes place in order to diminish these costs. In 2006, we carried out a case study in the Oderbruch region (Brandenburg, Germany) comprising eight Bt-maize growing...

New Zealand has a long history of producing official statistics on agricultural, horticultural, and forestry production. Having a good population or survey frame is a key factor enabling the collection and production of quality statistics. Several population frames have been used over time for agricultural production censuses and surveys. These include land based frames, administrative registers, farmer and grower lists, and combinations of these. This paper discusses the frame currently used and earlier frames and associated challenges, including: the transition from a land based to administrative frame, coverage issues, frame updating, and issues when comparing statistics based on different frames.

The Tariff-only Import Regime for Bananas in the European Union: Setting the Tariff at Right Level is Impossible Mission
Provedor de dados: 31
Autores: Guyomard,   Herve; Le Mouel,   Chantal; Levert,   Fabrice.
On 29 November 2005, the European Union (EU) unilaterally introduced a tariff of €176 per tonne to apply from 1 January 2006 to bananas imported from countries enjoying the Most Favoured Nation (MFN) status. The new EU trade policy includes a duty-free annual import quota of 775,000 tonnes for bananas originating from African, Caribbean and Pacific (ACP) states. This regime replaces the very complex and highly contested tariff-rate quota policy in place in the EU between 1993 and 2005. However, the banana international trade war very likely has not come to an end. Several Latin American countries have announced their intention to challenge the new EU trade policy by initiating a new WTO complaint. In this paper, we first propose an analysis of the two WTO...

What Does the “Family Smoking Prevention and Tobacco Control Act” Mean to Tobacco Growers?
Provedor de dados: 31
Autores: Tiller,   Kelly; Starnes,   Jane H.; Feleke,   Shiferaw T.
The “Family Smoking Prevention and Tobacco Control Act” was signed into law on June 22, 2009. The bill grants the Federal Food and Drug Administration (FDA) an authority to regulate the manufacturing and marketing of tobacco products. Tobacco leaf is not subject to the regulation. As a result, it is not apparent what it does mean to tobacco growers. However, since the demand for tobacco is in large part determined by the demand for cigarettes, a change in demand for cigarettes due to the FDA regulation can affect the demand for tobacco. This paper explores the economic welfare consequences of the bill to tobacco growers.

ANALYSIS OF THE WORLD OIL CROPS MARKET
Provedor de dados: 31
Autores: Mattson,   Jeremy W.; Sun,   Changyou; Koo,   Won W.
The world of oilseeds, meals, and oils has been evolving.  New issues have emerged for researchers and policymakers.  The United States is still the largest player, mainly due to its dominant position in soybeans and soybean meals.  Nevertheless, the position of the United States has been challenged by several countries.  The growth by Brazil and Argentina in the production of soybeans and soybean meal has especially eroded the market share of the United States in recent years.  Malaysia and Indonesia have been aggressively marketing their palm oil, intensifying the competition for U.S. soybean oil exports.  Other issues include changing trade policies and demand in major importing countries, trade liberalization, and genetically modified crops.

COMPARING END-USE VALUES FOR NORTH DAKOTA HARD RED SPRING WHEAT VARIETIES
Provedor de dados: 31
Autores: Lambert,   David K.; Wilson,   William W.
Markets for agricultural products may be inefficient when signals do not adequately reflect product characteristics important to market participants.  Although preferences can be explicitly stated through price premiums or characteristic values can be determined via hedonic methods, the problem is compounded when product quality information is costly to obtain.  Bundling of quality traits by variety can serve to signal product quality.  A procedure is developed in this paper to derive the value of different varieties in meeting buyer demands.  An application to the hard red spring market wheat both validates the ability of the procedure to distinguish among varieties, as well as provides empirical support to the existence of Akerlof's lemon market in the...

PRODUCER CONTRACT STRATEGIES IN GM CROPS
Provedor de dados: 31
Autores: Maxwell,   Brett J.; Wilson,   William W.; Dahl,   Bruce L.
A number of challenges exist for genetically modified (GM) crop development at the production level.  Contract strategies can resolve some of  these challenges.  Contracts can be designed to induce legal adoption of GM crops by varying technology fees, violation detection, and penalties.  The objective of this research is to analyze contracting strategies to determine terms to induce legal adoption of GM wheat and to minimize technology agreement violations.  A simulation model of the prospective introduction of GM technology into hard red spring wheat was developed.  Results illustrate that contracts can be designed to induce desired behavior.  Technology fees, probability of detection, and the level of non-GM premium were the most notable factors...

PRICE VARIABILITY AND FINANCIAL RISK FOR SUGAR BEET GROWERS
Provedor de dados: 31
Autores: Nganje,   William E.; Stoltman,   Gwen.
This paper develops a portfolio framework to characterize and analyze the impact of price risk faced by sugar beet growers in the Red River Valley and derives implications for capital markets.  Other sources of risk incorporated in the analysis are yields and production cost.  Results from stochastic simulation analysis reveal that sugar beet growers incur significant price and financial risk.  The hypothesis that the loan rate for sugar truncates the distribution of net returns and protects growers against declining beets prices was not validated.

Autores: Gomez-Limon,   Jose Antonio; Riesgo,   Laura.
Recently the olive sector has had important changes in Andalusia due to both the enlargement and the intensification of farming. The expansion of the olive grove in Andalusia is causing sustainability problems, not only from the socio-economic dimension (profit reduction) but environmental (erosion, water pollution or biodiversity losses). The main objective of this study is to develop a methodology to analyse the sustainability of the olive grove farms in Andalusia. This methodology will allow us to bear with the three dimensions of sustainability (economic, social and environmental) as well as to obtain a precise diagnosis of the olive grove through a selection of a set of indicators. This methodology will be applied in future research works in order to...

VARIABLE RATE NITROGEN APPLICATION ON CORN FIELDS: THE ROLE OF SPATIAL VARIABILITY AND WEATHER
Provedor de dados: 31
Autores: Roberts,   Roland K.; Mahajanashetti,   S.B.; English,   Burton C.; Larson,   James A.; Tyler,   Donald D.
Meta-response functions for corn yields and nitrogen losses were estimated from EPIC-generated data for three soil types and three weather scenarios.  These metamodels were used to evaluate variable rate (VRT) versus uniform rate (URT) nitrogen application technologies for alternative weather scenarios and policy option.  Except under very dry conditions, returns per acre for VRT were higher than for URT and the economic advantage of VRT increased as realized rainfall decreased from expected average rainfall.  Nitrogen losses to the environment from VRT were lower for all situation examined, except on fields with little spatial variability.

SOYBEANS QUALITY PRICE DIFFERENTIALS FROM AN ELEVATOR'S PERSPECTIVE
Provedor de dados: 31
Autores: Murova,   Olga I.; Mumma,   Gerald A.; Hudson,   Darren; Couvillion,   Warren C.
Soybean prices are determined by interaction between various factors.  At an elevator, discount prices for unique characteristics can range from 0.02 cents per bushel to 7.71 cents per bushel of soybeans.  This variation suggests that producers of soybeans need quality-characteristic specific information concerning soybeans pricing at the market.  This study uses a hedonic model to evaluate price differentials associated with soybean quality based on grain elevator data during the 1998 production period.  Foreign material, moisture, bean damage, and net weight were found to significantly influence the cash price of soybeans.

A Practical Algorithm for Multiple-Phase Control Systems in Agricultural and Natural Resource Economics
Provedor de dados: 31
Autores: Doole,   Graeme J.
Many important problems in agricultural and natural resource economics concern an intertemporal choice between alternate dynamic systems. This significance has motivated a theoretical literature generalizing the necessary conditions of Optimal Control Theory to multiple-phase problems. However, gaining detailed insight into their practical management is difficult because general numerical solution methods are not available. This paper resolves this deficiency through the development of a flexible and efficient computational algorithm based on a set of necessary conditions derived for finite-time, multiple-phase systems. Its effectiveness is demonstrated in an application to a nontrivial crop rotation problem.

We assess market integration and price transmission of perishable agricultural produce in Sub-Saharan Africa by studying Ghanaian tomato markets which are characterized by pronounced seasonality in production and trade flows. We analyse the tomato markets of Ghana by simultaneously regarding its five most important markets, Navrongo, Techiman, Kumasi, Tamale and Accra, in a multivariate asymmetric price transmission framework. The estimation of the model is based on a unique dataset and on a modified version of the Johansen estimation procedure which is suitable for estimating such multivariate models. We estimate the price transmission parameters for four regimes which are a combination of the seasonal patterns in trade flows and asymmetries in the...

How do farmers and agribusinesses decide whether to adopt site-specific crop management (SSCM)?  In spite of many agronomic experiments on variable rate fertilizer application, the broader adoption question has received little attention.  In order to discuss SSCM adoption issues, five focus group meetings were held with 22 Michigan farmers in early 1996 plus a sixth focus group meeting with 6 agribusiness representatives.  This report summarizes results, provides frequency counts of responses, and includes the questions that guided the focus group meetings.   The farmers interviewed were overwhelmingly concerned with profitability and risk of adopting SSCM.  Yield monitors were the most widely adopted SSCM technology; several farmers had hired grid soil...

Agricultural trade between the U.S. and Mexico has become progressively liberalized over the past 20 years, with significant increases in bilateral trade in many sectors. The rice sector in both nations, however, continues to be highly protected, with producers and millers on both sides of the border continuing to protest the other nation's protectionist policies. This paper examines market efficiency and spatial price integration in ten U.S. and Mexican rice markets over the 1998-2002 period, during which a retaliatory antidumping duty was imposed by Mexico. The paper uses a multiple step analytical process, including analysis of market price differentials, stationarity tests, bivariate and multivariate cointegration tests, and impulse response analysis....

Evaluation on HYV of Pulse crops in Myanmar
Provedor de dados: 31
Autores: Thaung,   Nyein Nyein; Choi,   Kyu Seob.
This paper shows the evaluation on HYV of pulse crops in Myanmmar. This system is evaluated based on growth decomposition model. The result of the area response function showed that the price of pulses was significant factor affecting farmers' land allocation decisions. The price of pulses and fertilizer, however, not affected output by influencing the utilization of inputs and hence, crop yield. The results of the area and yield response functions are consistent with the hypothesis of the study. The contribution of technology variables on changes in area, yield, and production will estimate by applying a decomposition model. The result showed that the adoption of HYVs and the increase in nitrogen use were the predominant sources of growth in pulses...

FQPA IMPLEMENTATION TO REDUCE PESTICIDE RESIDUE RISKS: PART I: AGRICULTURAL PRODUCER CONCERNS
Provedor de dados: 31
Autores: Batie,   Sandra S.; Swinton,   Scott M.; Schulz,   Mary A.
The Food Quality Protection Act of 1996 (FQPA) transforms the regulation of pesticide residues on food in the United States.  Three changes are prominent.  First, under the FQPA, the U.S.  Environmental Protection Agency (EPA) is authorized to develop uniform pesticide residue tolerances for both fresh and processed foods.  These tolerances must be based on a conservative standard appropriate for infants and children, rather than the adult-based tolerances that prevailed previously for fresh-market produce.  Second, under the FQPA, pesticide registration will be based upon aggregate risk to the most susceptible consumers from all pesticides sharing a common biochemical mode of action in humans.  Third, the FQPA expands the scope of health effects included...

Autores: Xu,   Z.; Guan,   Zhengfei; Jayne,   Thomas S.; Black,   J. Roy.
Major Findings: The additional maize produced from a given amount of fertilizer applied varied widely across households even after largely controlling for soil and rainfall conditions. The median estimated response rate was 15.9kgs of maize per kg nitrogen applied; Under the range of conditions and smallholder management practices, average maize fertilizer response rates declined as the application rate increased beyond 2 bags of urea and 2 bags of D compound; Factors raising the response rate and profitability of fertilizer use included timely availability, application rates less than the MOA 4x4 recommendation, use of animal draft power in land preparation, and use of hybrid seed. In remote areas, and given current management practices, fertilizer use...

Economic analysis of site-specific wheat management with respect to grain quality and separation of the different quality fractions
Provedor de dados: 31
Autores: Meyer-Aurich,   Andreas; Gandorfer,   Markus; Weersink,   Alfons; Wagner,   Peter.
The paper analyzes site-specific and uniform management options for wheat production with respect to grain quality. Besides site-specific fertilization the economic potential of segregation of different grain qualities is the subject of this paper. Yield and quality response to fertilizer were taken from field experiments in Germany to calculate site-specific response functions. The economic optima were calculated for uniform management (UM), complete separate management of the subfields (SM), site-specific fertilization (SSF) and grain segregation (GS) for different price structures according to different grain qualities. The results show that over all price structures, highest economic potential was found with SM or SSF compared to UM. However, these...

Benefit-Cost Analysis and Socio-Economic Considerations of Trypanosomiasis Control and Treatment in Northern Ghana
Provedor de dados: 31
Autores: Wahab,   S.; Asuming-Brempong,   Samuel.
The paper estimates the cost of tsetse control and treatment of trypanosomiasis and the benefits involved, using benefit-cost analysis. It also estimates the extent to which socio-economic characteristics of farmers affect the use of tsetse control techniques, using a maximum Likelihood-Binary Logit model. The results show that farmers will benefit if they invest in control and treatment of the disease. We find that the farmer accepting the challenge that the tsetse fly is a threat to cattle production, the number of dependants the farmer has, and the farmer agreeing that the bite of the tsetse fly causes the nagana disease are significant factors that affect adoption of control practices including the use of prescribed drugs. Our findings suggest that...

Autores: Gustafson,   Cole R.; Barry,   Peter J.; Sonka,   Steven T.
A combination of experimental and simulation procedures identify important factors in an Illinois cash grain farmer’s machinery investment decisions. In an experiment setting, a panel of farmers based investment decisions on their own expectations, farm situations, and varying policy scenarios. In general, the results show investment levels statistically related to the tenure and leverage of operators, the economic conditions they faced, and the age of existing machinery. Alternative public policies of lower commodity price supports, tax reform, and interest rate subsidies influenced the timing of purchases but did not alter total investment amounts.

Desarrollando mercados rurales: el rol de la incertidumbre y la restricción crediticia
Provedor de dados: 31
Autores: Escobal D'Angelo,   Javier.
El estudio evalúa cuáles son los factores más relevantes para que un pequeño productor agrícola demande asistencia técnica con el propósito de incursionar en mercados “dinámicos”; es decir, en mercados que puedan absorber cantidades crecientes de su cultivo. Los resultados muestran que existe un segmento de productores cuya “distancia” a estos mercados no es tan significativa como para que no puedan incursionar en ellos. Sin embargo, restricciones asociadas al grado de organización de los productores, a su percepción del riesgo y a las posibilidades de acceso al mercado de crédito les impiden acceder a los beneficios adicionales que estos mercados ofrecen.

Farming communities in water-scarce regions increasingly practice the use of urban wastewater in agriculture. Untreated urban wastewater is generally considered unacceptable for direct use because of potential health risks. However, in many parts of the world, poor farmers in peri-urban areas use untreated wastewater. This situation is considered likely to continue even in the foreseeable future due to the high investment cost associated with the installation of treatment facilities.

Globalization and competitiveness of agricultural commodities could have significant potential benefits for food security and poverty reduction in West Africa. Participation in global trade and economy is potentially important but not enough to ensure benefits at all levels of the chains and equitable distribution of income for each participant. Efficiency is key in the commodity value chain, but effective support functions and services, infrastructure, legal and policy environment are important. This paper presents the framework of value chain concept and analysis, as a guide to enhance competitiveness of commodities at national, regional or global level. The paper applies the value chain framework to a case study on mango in Benin, West Africa. The...

Effect of Farm-Level Constraints, Existing and Prospective Policies on Expansion of Coconut-Based Intercropping in Sri Lanka
Provedor de dados: 31
Autores: Fernando,   Neil; Edwards,   Ian E.; Thomson,   Kenneth J.; Daw,   Mike.
Coconut-based intercropping (CBI) in Sri Lanka was introduced some 20 years ago to overcome the two main limitations of traditional coconut monocropping, inefficient land use and low incomes to farmers, but it has not been widely adopted. This study analyses the effect of farm-level resource constraints, and government policies on the intensity of adoption of CBI. A multiperiod linear programming (MLP) model was applied for three farmer groups - resource poor, medium endowed, well endowed - categorised using cluster analysis. Data was collected from a survey of randomly selected 113 intercroppers. Empirical results reveal that expansion of CBI is mainly constrained by seasonal labour shortages for all farmer groups, particularly the well endowed, and by...

Recognizing that the green revolution has resulted in considerable success in production of rice and wheat in many Asian countries, which are now self-sufficient or surpluses in these cereals, IFPRI believes that further growth in agriculture will rely on the productivity of these countries to diversify their agricultural production, while improving productivity in cereals through management and human capital-intensive increase in yield levels. Indonesia is an important example of a country where policy successes in rice production combined with other domestic and world developments in the economic environment of agriculture encouraged policymakers to consider agricultural diversification policies. Key developments leading to an increased interest in...

FACTORS AFFECTING ADOPTION OF IMPROVED MAIZE SEEDS AND USE OF INORGANIC FERTILIZER FOR MAIZE PRODUCTION IN THE INTERMEDIATE AND LOWLAND ZONES OF TANZANIA
Provedor de dados: 31
Autores: Kaliba,   Aloyce R.; Verkuijl,   Hugo; Mwangi,   Wilfred.
This paper examines factors influencing the adoption of improved maize seeds and the use of inorganic fertilizer for maize production by farmers in the intermediate and lowland zones of Tanzania. The results indicate that availability of extension services, on-farm field trials, variety characteristics and rainfall were the most important factors that influenced the extent of adopting improved maize seeds and the use of inorganic fertilizer for maize production. Farmers preferred those varieties which minimize field loss rather than maximizing yields. Future research and extension policies should emphasize farmer participation in the research process and on-farm trials for varietal evaluation and demonstration purposes.

SOFT WHITE AND SOFT RED WHEAT PRODUCTION AND MARKETING IN MICHIGAN:  IMPORTANCE SUPPLY, DEMAND, PRICE BEHAVIOR, AND FUTURES MARKET RELATIONSHIPS
Provedor de dados: 31
Autores: Carman,   Garth A.
Many different classes of wheat are grown in Michigan's agriculture sector but only two types of wheat are grown to any significant degree.  Easily the most dominant type of wheat grown is soft white wheat which is a sub-class of white wheat.  The other class of wheat grown in Michigan is soft red wheat.  Since these two wheat crops comprise consistently over 90% of the wheat acreage in Michigan this analysis will only be concerned with them.  The purpose of this study is to examine the trade-offs in producing and marketing soft white and soft red wheat in Michigan for the purpose of identifying optimal strategies for the participants.  The uses of both types of wheat will be examined as well as the impact of new technology on the substitutability of soft...

Agriculture is the largest sector in the economy of Sierra Leone, employing approximately 75 percent of the population in 1972 and accounting for over 30 percent of the gross domestic product.  But though the national economy has grown at an estimated 4.3  percent rate in the last decade, the agricultural sector is estimated to have grown only 1.6 percent per year.  The government of Sierra Leone, recognizing the importance of the agricultural sector and the need to develop policies to encourage its growth, has set a goal of increasing the growth rate of the sector to 4.6 percent per annum.  Central to the overall agricultural development plan is the emphasis on increased rice production.  Rice is the staple food in Sierra Leone, grown by over 80 percent...

GRAIN MARKETING POLICY CHANGES AND SPATIAL EFFICIENCY OF MAIZE AND WHEAT MARKETS IN ETHIOPIA
Provedor de dados: 31
Autores: Negassa,   Asfaw; Myers,   Robert J.; Gabre-Madhin,   Eleni Z.
In the context of on-going market reform in developing countries, there is a need for an improvement in the existing methods of spatial market efficiency analysis in order to better inform the debate toward designing and implementing new grain marketing policies, institutions, and infrastructure that facilitate the emergence of a well developed and competitive grain marketing system. The standard parity bounds model (PBM), while it overcomes many weaknesses of the conventional methods of spatial market efficiency analysis, it does not allow for the test of structural changes in spatial market efficiency as a result of policy changes. In this paper, building on the standard PBM, we develop an extended parity bounds model (EPBM). The EPBM is a stochastic...

Income-led growth in demand for meat is expected to provide the major stimulus for expansion in the Philippine corn sector. Traditionally eaten as a cheaper carbohydrate substituting for rice by many Filipinos, corn is now increasingly being used to grow corn, which has displaced rice as the most important crop in terms of cultivated area.  In recent years, the Philippine government had vigorously pursued a series of sectoral and economy wide policy reforms to invigorate the corn sector and support the feed requirements of the livestock industry. These reforms include more liberal foreign exchange policies, lifting of control over domestic marketing operations, deregulation of the interisland transportation system, and production- augmenting programs.

Autores: Farrigan,   Tracey L.; Durst,   Ron L.
Over the past two decades, the Federal tax code increasingly has been used as a tool for achieving social and other policy objectives, primarily through the expanded use of tax credits. A larger share of rural taxpayers benefit from Federal tax policies aimed at lower income taxpayers because they have historically had lower incomes and higher poverty rates than urban households. The earned income and child tax credits have provided a substantial boost in income to low and middle-income rural taxpayers and have reduced the rural poverty rate.

The Impact of Coordination of Production and Marketing Strategies on Price Behavior: Evidence from the Idaho Potato Industry
Provedor de dados: 31
Autores: Bolotova,   Yuliya; McIntosh,   Christopher S.; Muthusamy,   Kalamani; Patterson,   Paul E.
High potato price volatility, decreasing demand for fresh potatoes and prices below the cost of production led to a decision of a number of Idaho potato growers to organize the United Fresh Potato Growers of Idaho, a marketing cooperative. The programs and strategies of the cooperative target both the production and marketing of fresh potatoes in Idaho. To evaluate the effectiveness of the programs implemented by the cooperative, we examine the level and volatility of fresh potato prices during two periods: before the cooperative was organized and when the cooperative is in the market. We find empirical evidence suggesting that fresh potato prices were higher and less volatile during the period when the cooperative was in the market.

An Empirical Analysis of the Effects of Plant Variety Protection Legislation on Innovation and Transferability
Provedor de dados: 31
Autores: Srinivasan,   Chittur S.; Shankar,   Bhavani; Holloway,   Garth J.
Under the TRIPs Agreement, all member-countries of the World Trade Organization are required to provide an "effective" system of plant variety protection within a specific time frame. In many developing countries this has led to a divisive debate about the fundamental desirability of extending intellectual property rights to agriculture. But empirical studies on the economic impacts of PVP, especially its ability to generate large private sector investments in plant breeding and facilitate the transfer of technology, have been very limited. This paper examines two aspects of the international experience of PVP legislation thus far (i) The relationship between legislation, R&amp;D expenditures and PVP grants, i.e., the innovation effect, and (ii) The role...

Reductions of Agricultural Nitrogen Use Under Consideration of Production and Price Risks
Provedor de dados: 31
Autores: Finger,   Robert.
Production and price risks affect optimal nitrogen use as well as the effects of nitrogen taxation if farmers’ risk aversion is taken into account. Our empirical analysis for Swiss maize production shows that risk-aversion leads to lower levels of nitrogen application, and nitrogen taxes lead to higher reductions of nitrogen use for risk-averse than for risk-neutral farmers. Moreover, risk-averse farmers face lower abatement costs. Sensitivity analyses, that consider expected shocks in price and yield variability in Swiss maize production, show that these differences between risk-averse and risk-neutral farmers will increase further. Thus, agricultural policies should consider farmers’ risk-preferences as well as potential increases in farmers’ income risks.

ECONOMIC PROSPECTS FOR SPRINKLE IRRIGATING RICE IN TEXAS
Provedor de dados: 31
Autores: Griffin,   Ronald C.; Rister,   M. Edward; Parker,   Michael R.; McCauley,   Garry N.
The economic feasibility of investing in sprinkler irrigation technology for rice production is investigated using linear programming and capital budgeting to identify the net annual benefits and net present value, respectively.  Groundwater and both flat rate and volumetrically priced surface water sources of irrigation water are analyzed.  Under typical practices occurring in rice production operations in the Texas Rice Belt, sprinkler irrigation technology is not profitable at current water costs.  Producers using volumetrically priced surface water have the greatest incentive to consider sprinkler irrigation, but water prices must increase by over 250 percent for the investment in a sprinkler irrigation system to become attractive.  Yield reductions...

Discussion: Animal Identification Systems in North America: Achievements and Future Challenges
Provedor de dados: 31
Autores: Knutson,   Ronald D.
Although Canada has developed an effective animal identification system, and the provinces are progressing toward a system that has full traceback capabilities, the U.S. and Mexico have made little or no progress. Contemporary U.S. proposals for state initiatives will not work. In the meantime, the U.S. livestock industry will continue to lose markets for its products and has little to no basis for complaining about lost sales and the lack of open markets. Also indentified are relevant economic and political principles that both underlie animal identification systems and the failure to make positive steps forward toward establishing a North American animal identification system.

Autores: Engel,   Anna-Maria; Wegener,   Jens Karl; Lange,   Marco.
Organic farming is the most adequate system for the production of food and other agricultural 9 products to sustain ecological and environmental sources. Ecologically produced foods are 10 becoming more and more popular; accordingly, the demand for organic products is growing. In 11 addition to the renunciation of the use of chemical fertilisers and pesticides, the philosophy of 12 this type of food production includes as well the benefits of seasonal and regional goods such 13 as short ways of production and distribution. 14 In the present study the total emissions of greenhouse gases (GHG) in the production of 15 organic apple juice from two different regions were investigated.

AN IRRIGATION MODEL FOR MANAGEMENT OF LIMITED WATER SUPPLIES
Provedor de dados: 31
Autores: Bernardo,   Daniel J.; Whittlesey,   Norman K.; Saxton,   Keith E.; Bassett,   Day L.
A two-stage simulation/mathematical programming model is presented for determining the optimal intraseasonal allocation of irrigation water under conditions of limited water supply. The model is applied to a series of water shortage scenarios under both surface and center pivot irrigation. Economically efficient irrigation management is shown to involve the coordination of a number of managerial decisions, including irrigation scheduling, crop substitution, the adoption of improved irrigation labor practices, and idling land. The results indicate that significant opportunities exist for conserving water in the study area under both surface and center pivot irrigation.

ANALYSIS OF DRY BEAN PRICE BEHAVIOR IN BURUNDI
Provedor de dados: 31
Autores: Ndarusigiye,   Mevin.
Dry bean production and price statistics for Burundi from 1972 to 1987 indicate significant year-to-year (bean production) and monthly (bean prices) fluctuations.  These fluctuations are influenced by, among other things, climatic conditions, unpredictable markets, government policy, and phytopathological factors.  The objective of the study is to analyze the behavior of dry bean production in Burundi under uncertain prices and assess the degree of uncertainty for the period 1972-1987.  The hypotheses are that dry bean prices in Burundi are uncertain, and that annual dry bean production per capita has been falling because of dry bean price uncertainty.  Two types of regressions models, one with average annual data and another with monthly real price data,...

A REGIONAL CROP ACREAGE MODEL:  ESTIMATION OF ACREAGE RESPONSE TO GOVERNMENT PROGRAMS FOR THE EAST SOUTH CENTRAL REGION IN THE U.S. WITH A FORECAST FOR 1982-1985
Provedor de dados: 31
Autores: Wu,   Tzongyun Katy.
Since the early 1930's, congress has established a number of programs intended to soften the impact of economic forces upon farmers.  These programs seek to adjust production to utilization on a year-to-year basis by offering incentives to producers to expand or contract their crop planting.  As a result, accurate estimates of producer response to changing market prices and government programs are very important for policy makers as they attempt to adjust programs to balance demand and supply.  Good forecasts of future crop acreages can also help economists provide producers and agribusinesses with better guides for strategies and planning, marketing, and production decisions.  The objective of this study is to forecast acreage planted for a specific...

FARM LEVEL DEMAND FOR PECANS RECONSIDERED
Provedor de dados: 31
Autores: Wells,   Gary J.; Miller,   Stephen E.; Thompson,   C. Stassen.
Previous studies have consistently indicated the anomalous result of a price inflexible demand for pecans.  However, these efforts did not have an adequate measure of pecan stocks available and, as a result, stocks were either excluded from consideration or a proxy variable was introduced.  A time series of pecan stocks is now available.  Use of this time series in a price dependent demand function results in a flexible farm level demand for pecans.  This points out the danger of excluding an appropriate variable or using a so-called "reasonable" proxy variable.

Economics, Ecology and GMOs: Sustainability, Precaution and Related Issues
Provedor de dados: 31
Autores: Tisdell,   Clement A.
Ecological, evolutionary and economic issues involved in introducing genetically modified organisms (GMOs), mainly in agriculture, are discussed. The ecological and evolutionary impacts identified hamper (economic) valuation of GMOs and their biosafety regulation and creates difficulties for planning for sustainable development. Assessment of the desirability of releasing GMOs is difficult because of lack of communal agreement about the risks involved, about how much precaution should be exercised given collective risks, and disagreement on the appropriate social criterion to apply. Changes in legal liability are not always economic and cannot eliminate the social conflict generated by GMOs. The economics of developing and marketing GMOs is explored,...

POTENTIAL CORN ACREAGE EXPANSION FOR ETHANOL PRODUCTION: WESTERN NORTH DAKOTA--MINOT
Provedor de dados: 31
Autores: Gustafson,   Cole R.
Several recent developments have stimulated farmers' interest in raising corn for ethanol production in northwestern North Dakota.  The purpose of this study is to estimate the corn supply response of western North Dakota farmers for ethanol production.  Two focus groups of western North Dakota farmers (Williston and Minot) were organized.  The market premium over prevailing local corn prices that was required by western North Dakota farms to entice additional production of an ethanol specific hybrid was determined.  Aggregation of these farm responses yielded a supply function of corn for the region.  Results show that sufficient corn can be produced in the surrounding region to support a 12 million gallon ethanol facility if modest price premiums are...

This paper reports the analysis of two groups of wheat producers: American White Wheat Producers Association members who produce white wheat under contract with the cooperative and those who have chosen not to do so.  The results show the diversity of producers’ attitudes, preferences, knowledge and decision making.  Nonmembers tend to rely more on short-term profitability and are less willing to risk innovation for unproven profits.  Nonmembers also are less supportive of contract production and less inclined to use a young cooperative in that situation.  This study demonstrates that the development of a new coordination mechanism entails much education of participants and that producer involvement also depends on learning on the part of everyone in the...

Nationally, Florida ranked second in farm cash receipt from all crops and second, based on value, in vegetable production (USDA, 2003). It also ranked fourteenth out of all the states with respect to agricultural exports with its top exports, fruits and vegetables, falling within the category of specialty crops. According to the USDA (2003), Florida's agricultural exports help to boost farm prices and income and supported approximately 17,000 jobs both on and off farm in 2001, and as such are important to Florida's agricultural and statewide economy. From a Florida farm cash receipts perspective, increased imports could undermine revenue earnings from specialty crop production, especially if there is not a comparable growth in the exports of these crops....

Carbon sequestration through the planting of multi-annual energy crops: A dynamic and spatial assessment
Provedor de dados: 31
Autores: de Cara,   Stephane; Rozakis,   Stelios.
In this study, we examine the spatial and dynamic implications of policies aimed at increasing carbon sequestration in agricultural soils. We consider incentive mechanisms designed to encourage the planting of energy multi-annual crops that allow higher carbon sequestration rates for a longer period of time. By using a dynamic micro-economic model, we simulate the sequence of crop plantings over a given time horizon and investigate different payment mechanisms (per-ton or per-hectare). We discuss their implications in terms of regulation policy and efficiency. This model is then applied to the Central Plains of Thessaly, Greece, to assess the marginal costs of carbon sequestration and the optimal timing of switching to multi-annual energy crops. To do so,...

There is ample evidence to suggest that Sri Lanka’s climate has already changed. However, the bigger question of national importance is what Sri Lanka’s climate will look like in 50 or 100 years and how prepared the country is to face such changes. This report reviews the status of climate change (CC) research/activities in Sri Lanka in terms of observed and projected climatic changes, their impacts on water resources and agriculture, CC mitigation and adaptation, and research needs. The study also developed a pilot level CC Vulnerability Index, which was subsequently mapped at district level. The maps indicate that typical farming districts such as Nuwara Eliya, Badulla, Moneragala, Ratnapura and Anuradhapura are the most vulnerable to CC due to their...

We extend a multi-equation structural model of crop acreage response, insurance participation, CRP enrollment, and input usage developed in Goodwin and Vandeveer (2000) to wheat and barley production in the "Northern Great Plains" region. We also update earlier results for corn and soybean production in the "Heartland" region. Our results confirm earlier findings that increased participation in insurance programs provoke a statistically significant acreage response. This response is, however, relatively modest.  We find that cross-the-board decreases of 50% in insurance premiums significantly increase...

CHINA'S COTTON POLICY AND THE IMPACT OF CHINA'S WTO ACCESSION AND BT COTTON ADOPTION ON THE CHINESE AND U.S. COTTON SECTORS
Provedor de dados: 31
Autores: Fang,   Cheng; Babcock,   Bruce A.
In this paper we provide an analysis of China's cotton policy and develop a framework to quantify the impact of both China's World Trade Organization (WTO) accession and Bt (Bacillus thuringiensis) cotton adoption on Chinese and U.S. cotton sectors. We use a Chinese cotton sector model consisting of supply, demand, price linkages, and textiles output equations. A two-stage framework model provides gross cropping area and total area for cotton and major substitute crops from nine cotton-producing regions in China. Cotton demand, total fiber demand, and cotton share are estimated for each end user. The estimated parameters from the Chinese model are then used with the Food and Agricultural Policy Research Institute (FAPRI) modeling system to simulate various...

Best Management Practices: How Economical is it in Southern Agricultural Systems?
Provedor de dados: 31
Autores: Matekole,   Augustus N.; Westra,   John V.; Appelboom,   Timothy W.
Conventional drainage systems tend to aggravate runoff and nutrient leaching problems on farms especially during the off-season. This study uses a biophysical economic model to identify, evaluate and determine multifunctional benefits of implementing and establishing nitrogen rate fertilizer application and conservation tillage practices as best management practices (BMPs) in the lower Mississippi River Basin (MRB). Simulation results showed that agricultural producers generally preferred no tillage to conventional tillage in reducing nutrient runoffs from fields because of higher net revenue per acre. Finally, given nitrogen runoff restrictions, farmers reduced crop acreage and nitrogen fertilizer application rates to help minimize losses.

Economics and Marketing of Aromatic Rice - A Case Study of Chhattisgarh
Provedor de dados: 31
Autores: Marothia,   Dinesh K.; Singh,   R.K.; Chandrakar,   M.R.; Jain,   B.C.
In recent years there has been a serious concern among the farmers, scientists, policymakers and environmentalists regarding the continuous erosion of genetic biodiversity of rice cultivars in Chhattisgarh which has traditionally been known as bowl of scented rices in central India. In view of India’s potential competitiveness in aromatic rices in the international market, it is imperative to understand the dynamics of domestic trade in aromatic rice. In this study, marketing and price-spread patterns of aromatic rice in the state of Chhattisgarh have been examined. A few policy interventions have been suggested for promoting aromatic rices in the state.

A framework for combining extraneous information with an econometric model to evaluate the economic impacts of pesticide withdrawals is presented in this paper. The extraneous information, which can be a best guess or experimental data, is used to shift an econometrically estimated supply function. The full sectoral econometric model is then simulated through time with and without the supply shift to estimate the relative impacts of withdrawing the pesticide. The theoretical framework is applied to the withdrawal of all insecticides used on cotton.

Seasonal Farm Price Patterns in Selected U.S. Fresh Fruit Markets
Provedor de dados: 31
Autores: Plattner,   Kristy; Perez,   Agnes C.; Thornsbury,   Suzanne.
Our poster analyzes seasonal farm price patterns in five major U.S. fresh fruit markets (i.e. strawberries, apples, oranges, peaches and grapes) between 1980 and 2010. Shifts in the seasonal patterns between decades (1980-89, 1990-99, and 2000-10) signal price response to changes in market conditions, demand trends, and global linkages that have taken place overtime in these fruit markets.  Statistical comparatives and graphical analysis form the basis for assessment using U.S. Department of Agriculture, National Agricultural Statistics Service (NASS) monthly grower price data. Extended seasons through geographical and varietal diversity in major producing areas have had a smoothing effect on the seasonal behavior of fresh strawberry prices but a distinct...

Revisiting N fertilisation rates in low-rainfall grain cropping regions of Australia: A risk analysis
Provedor de dados: 31
Autores: Monjardino,   Marta; McBeath,   T.; Brennan,   Lisa E.; Llewellyn,   Rick S.
Mallee farmers minimize downside risk in dry seasons by applying low rates of nitrogen (N) fertiliser to their cereal crops. The opportunity to respond to and capitalize on the better years is further limited as most inputs are applied upfront at sowing. We used an economic-risk decision model to identify a range of tactical N fertilisation options that increase net returns, while minimising risk for farmers with different risk attitudes. Importantly, we concluded that when accounting for long-term risks affecting farmers, the use of higher N rates can play a risk-reducing role in a highly variable environment like the Mallee.

Economics of Groundwater Irrigation in Nepal:  Some Farm-Level Evidences
Provedor de dados: 31
Autores: Bhandari,   Humnath; Pandey,   Sushil.
This article examines the economics of groundwater irrigation and shallow tubewell (STW) ownership decision making, using farm-level data collected from 324 households in Nepal.  STW irrigation generated a significant positive effect on rice yield and farmers’ incomes.  Based on a probit model, the farm size, land fragmentation, access to electricity, and access to credit were found to significantly influence farmers’ decisions to own STWs.  Although the water market benefited poor farmers, it is too small and monopolistic.  Policy reforms needed to make groundwater accessible to the poor majority include effective credit programs, investments in rural electrification, and public sector support for promoting suitable pumping technologies

Impact of High Crop Prices on Environmental Quality: A Case of Iowa and the Conservation Reserve Program
Provedor de dados: 31
Autores: Secchi,   Silvia; Babcock,   Bruce A.
Growing demand for corn due to the expansion of ethanol has increased concerns that environmentally sensitive lands retired from agricultural production into the Conservation Reserve Program (CRP) will be cropped again. Iowa produces more ethanol than any other state in the United States, and it also produces the most corn. Thus, an examination of the impacts of higher crop prices on CRP land in Iowa can give insight into what we might expect nationally in the years ahead if crop prices remain high. We construct CRP land supply curves for various corn prices and then estimate the environmental impacts of cropping CRP land through the Environmental Policy Integrated Climate (EPIC) model. EPIC provides edge-of-field estimates of soil erosion, nutrient loss,...

Modeling Yield Risk Under Technological Change: Dynamic Yield Distributions and the U.S. Crop Insurance Program
Provedor de dados: 31
Autores: Zhu,   Ying; Goodwin,   Barry K.; Ghosh,   Sujit K.
The objective of this study is to evaluate the risk associated with major agricultural commodity yields in the United States. We are particularly concerned with the nonstationary nature of the yield distribution, which arises primarily as a result of technological progress and changing environmental conditions over time. In contrast to common two-stage methods, we propose an alternative parametric model that allows the moments of yield distributions to change with time. Several model selection techniques suggest the proposed time-varying model outperforms more conventional models in terms of in-sample goodness-of-fit, out-of-sample predictive power, and the prediction accuracy of insurance premium rates.

This paper examines the market potential for fresh organic lettuce and water melon with a recently collected data on consumers from Kumasi metropolis of Ghana. Using a doublebounded dichotomous choice contingent valuation technique, consumer’s willingness to pay is estimated with a Tobit model to address the zero willingness to pay responses in the sample data. As much as 71% of the consumers are willing to pay over 50% price premiums for organic vegetables and over 82% are willing to pay 1%–50% price premiums for organic fruits. The empirical results indicate that human capital, product attributes and consumer perception influence consumers’ willing to pay for organic food products.

Autores: Boussios,   David; Barkley,   Andrew P.
This research identifies and quantifies the impact of biophysical and economic variables on Kansas grain supply for the period 1977- 2007. This research estimates total supply response by aggregating yield and acreage responses. Previous methods have effectively analyzed the response of crop supply through either acreage or yield responses. However, the method proposed in this research incorporates both yield and acreage response to various production variables through recursive modeling. The results include the negative impact of acreage expansion on aggregate yields and thus the impact on total supply. The results also show that previous methods underestimate supply response elasticities by as much as 97%. Furthermore, this research estimates supply...

The gross and net margins for a representative sample of 53 Scottish potato producers classed as "Seed" (&gt;80% of area grown for seed), "Ware" (&gt;80% of area grown for Ware) and "Mixed" for the rest were obtained for the 1999 growing season according to the methodology of MAFF (1990,1999). The farms were arable. Yields were average but for seed growers for whom tuber number in the seed size is more important. Prices were the lowest for six years variable costs were high and gross margins are above the best for cereals. However fixed costs excluding seasonally rented land are considerable leaving negative net margins. Potato price fluctuates widely. Prices were high in 1998. Applying these prices to the 1999 data left good net margins. Average prices...

Autores: Binfield,   Julian C.R.; Westhoff,   Patrick C.; Le Cadre,   Elodie.
The impact of increased consumption of biofuels on agricultural markets has already been substantial, and will increase further as countries around the world seek to expand the proportion of their energy that they get from renewable sources. Models of the agricultural sector must therefore include some consideration of the demand for agricultural products for biofuels and the byproducts that are produced as part of the production process that are returned to the agricultural sector. In this paper the method of introducing biofuels into the FAPRI GOLD (grains, oilseeds, livestock and dairy) model is discussed. A scenario is run whereby the EU is assumed to introduce a binding 10% target by 2020 and the results are discussed in order to illustrate the...

A Value Chain Task Force Approach for Managing Private-Public Partnerships:  Zamiba’s Task Force on Acceleration of Cassava Utilization.
Provedor de dados: 31
Autores: Chitundu,   Maureen; Droppelmann,   Klaus; Haggblade,   Steven.
Smallholder farmers operate in vertical supply chains. Therefore, an understanding of key opportunities and constraints up through the value chain becomes necessary for sustaining smallholder growth. Yet market analysis is of little value unless key private and public sector stakeholders agree to implement necessary reforms. This paper advocates an approach which marries together value chain analysis with a stakeholder taskforce to ensure that analysis of opportunities and constraints gets translated into actions that will facilitate commercial growth. Using Zambia’s cassava task force as an example, the paper describes the value chain task force method and identifies elements critical to its effective implementation.

Stochastic Efficiency with Respect to a Function (SERF) is used to rank transgenic cotton technology groups and place an upper and lower bound on their value. Yield and production data from replicated plot experiments are used to build cumulative distribution functions of returns for nontransgenic, Roundup Ready, Bollgard, and stacked gene cotton cultivars. Analysis of Arkansas data indicated that the stacked gene and Roundup Ready technologies would be preferred by a large number of risk neutral and risk averse producers as long as the costs of the technology and seed are below the lower bounds calculated in this manuscript.

Crop Choice, Non-Target Pest Levels, Yield Loss and Their Effect on Insecticide Use in South Dakota
Provedor de dados: 31

Agriculturally, South Dakota is a unique state possessing the highest rate of adoption for genetically modified crop varieties.  In 2009 ninety-six percent of corn acres planted in South Dakota were genetically modified compared with eighty-five percent nationally (Economic Research Service).  Additionally, South Dakota has seen a dramatic increase in the number of acres treated with insecticide over the past 20 years.  These two situations taken together seem to be counterintuitive.  Some genetically modified varieties, such as Bt corn, are equipped with genetic defenses so that they can protect the plant from target pests.  Intuitively, one would expect to see a decrease in insecticide use as adoption of genetically modified varieties increase.  Recent...

The Restructuring of the Saskatchewan Wheat Pool: Overconfidence and Agency

This paper examines how agency problems combined with overconfidence and hubris by coop management lead to financial failure in the Saskatchewan Wheat Pool. As a consequence of both of these problems, the Pool made poor investment decisions and ended up in severe financial difficulties. These problems were exacerbated by three additional factors: (1) ownership and control were separated via an A-B share structure, leading to a situation where neither farmer members nor investors had an incentive to monitor management activities; (2) the sheer volume of investment activity undertaken made it virtually impossible for the board to stay on top of what was happening; and (3) as a result of the change financial structure, senior management had available a large...

Economics of spatial coexistence of genetically modified and conventional crops: Oilseed rape in Central France
Provedor de dados: 31
Autores: Demont,   Matty; Daems,   W.; Dillen,   Koen; Mathijs,   Erik; Sausse,   C.; Tollens,   Eric.
Europe is currently struggling to implement coherent coexistence regulations on genetically modified (GM) and non-GM crops in all EU Member States. We conduct simulations with the software ArcView® on a GIS dataset of a hypothetical case of GM herbicide tolerant oilseed rape cultivation in Central France. Our findings show that rigid coexistence rules, such as large distance requirements, may impose a severe burden on GM crop production in Europe. These rules are not proportional to the farmers’ basic incentives for coexistence and hence not consistent with the objectives of the European Commission. More alarming, we show that in densely planted areas a domino-effect may occur. This effect raises coexistence costs and even adds to the non-proportionality...

In order to meet the changing needs and preferences of consumers it will be important for Belgian glasshouse growers to change from a production-driven to a customer-driven strategy. More than ever, use of information and product innovation become critical factors in the changing competitive environment. The aim of the research is to analyse the relationship between business and managerial characteristics, use of information sources, product innovation and financial performance of the firm. The results indicate that the average Belgian glasshouse grower makes low use of external information sources for production decisions. However an important variation in information use can be observed among the growers. The results reveal that vegetable producers make...

The Effects of the Micro-Market Structure for Kansas Grain Elevators on Spatial Grain Price Differentials
Provedor de dados: 31
Autores: O'Brien,   Daniel M.
Corn and wheat cash prices in Kansas are affected by a number of local supply-demand, market structure, transportation access and other factors. Kansas corn prices in 2008 were affected by form of business organization, local feedgrain production and livestock feed usage, elevator storage capacity, access to railroad grain handling facilities, and to a limited degree by the number of competitors in local markets. Geographic proximity to grain ethanol plants did not have a positive impact on local corn prices, although a number of mitigating factors may exist. Kansas wheat prices in 2008 were affected by local wheat production, elevator storage capacity, the number of competitors in local markets, and by location relative to flour mills. Evidence of...

Optimal management of annual ryegrass ( Lolium rigidum Gaud.) in phase rotations in the Western Australian Wheatbelt
Provedor de dados: 31
Autores: Doole,   Graeme J.
Lucerne ( Medicago sativa L.) helps to prevent soil salinisation in the Western Australian Wheatbelt by reducing recharge to saline water tables. There is broad consensus, though, that it is not sufficiently profitable to motivate producers to plant it at the intensity at which considerable off-site benefits would be conferred. This paper employs a multiple-phase optimal control model to explore the value of this perennial pasture for the management of herbicide-resistant annual ryegrass ( Lolium rigidum Gaud.) in a crop–pasture rotation, given the difficulty of observing this value in practice. The availability of selective herbicides for efficient weed control is found to determine whether or not it is profitable to adopt lucerne pasture under optimal...

Farmers’ Awareness and Use of IPM for Soybean Aphid Control: Report of Survey Results for the 2004, 2005, 2006, and 2007 Crop Years
Provedor de dados: 31
Autores: Olson,   Kent D.; Badibanga,   Thaddee Mutumba; DiFonzo,   Christina.
In response to the introduction and rapid spread of soybean aphid, farmers in the Upper Midwest were surveyed about their treatment of and knowledge about soybean aphids for crop years 2004, 2005, 2006, and 2007. Overall, the farmers showed a fairly good understanding of soybean aphids and their impact on soybeans. Over 80% said soybean aphids could be treated and repopulate in the same crop year. For 2004-2006, at least 75% of the farmers said aphids damaged their soybeans by sucking sap. However this percentage dropped to 59% for 2007 with a greater percentage pointing at a combination of damage methods. This lower percentage for 2007 may be due to a broader, randomly selected sample of farmers who received the surveys by mail versus farmers who attended...

Discounting Spotted Apples: Investigating Consumers’ Willingness to Accept Cosmetic Damage in an Organic Product
Provedor de dados: 31
Autores: Yue,   Chengyan; Alfnes,   Frode; Jensen,   Helen H.
The appearance of organic produce is often less than perfect because of limited methods of avoiding plant diseases. We combine hypothetical and real auction mechanisms to investigate how cosmetic damage affects consumers’ willingness to pay for apples. We find that 75% of the participants are willing to pay more for organic than for conventional apples given identical appearance. However, at the first sight of any imperfection in the appearance of the organic apples, this segment is significantly reduced. Furthermore, the cosmetic damage has a larger impact on the willingness to pay for organic apples than for conventional apples.

Quantile Regression Estimates of Confidence Intervals for WASDE Price Forecasts
Provedor de dados: 31
Autores: Isengildina-Massa,   Olga; Irwin,   Scott H.; Good,   Darrel L.
This study uses quantile regressions to estimate historical forecast error distributions for WASDE forecasts of corn, soybean, and wheat prices, and then compute confidence limits for the forecasts based on the empirical distributions. Quantile regressions with fit errors expressed as a function of forecast lead time are consistent with theoretical forecast variance expressions while avoiding assumptions of normality and optimality. Based on out-of-sample accuracy tests over 1995/96–2006/07, quantile regression methods produced intervals consistent with the target confidence level. Overall, this study demonstrates that empirical approaches may be used to construct accurate confidence intervals for WASDE corn, soybean, and wheat price forecasts.

Modelling the impact of private quality standards on the fresh fruit and vegetable supply chains in developing countries
Provedor de dados: 31
Autores: Fontaine,   Damien; Gaspart,   Frederic; Frahan,   Bruno Henry de.
Stricter quality requirements and greater uses of private quality standards have a considerable impact on the fresh fruit and vegetable supply chain in developing countries. In particular, the future of small-scale production is in doubt. This paper presents a theoretical game theory model to study the impact of quality requirements on producer and consumer welfare within certified supply chains. The model shows that total producer welfare is maximized at higher quality levels where farmers who are efficient in the production of quality products participate, whilst less efficient producers are excluded. In addition, the model provides useful insights on welfare and poverty impact of increased competition and changes in private standard certification costs.

Crop Production Using Variable Rate Technology for P&amp;K in the United States Midwest: Evaluation of Profitability
Provedor de dados: 31
Autores: Bolotova,   Yuliya.
This study evaluates profitability of crop production with variable rate technology (VRT) for P&amp;K application relative to profitability of crop production with uniform rate technology (URT) using data from six fields with a corn-soybeans rotation situated in Indiana. The results suggest that crop production using VRT is more profitable than using URT in one of the six fields. In the case of the other five fields profitability of crop production using VRT relative to using URT falls in the range of 85 to 92%. Under the assumption of lower costs for field diagnostic services and variable rate fertilizer application profitability of crop production using VRT increases.

Market Structure Impacts on Market Distortions from Domestic Subsidies: The U. S. Cotton Case
Provedor de dados: 31
Autores: Pan,   Suwen; Hudson,   Darren; Ethridge,   Don E.
This analysis uses a residual demand elasticity model to measure market power in the international cotton market. The results indicate that China exerts significant market power and affects cotton prices. Those results, combined with a partial equilibrium model of the international cotton market, are used to evaluate the welfare consequences of U.S. cotton subsidy policies for major cotton exporters under alternative assumptions about global market structure. The results indicate that the effects of U.S. subsidies on the world cotton price are much smaller under an imperfectly competitive international market than under a perfectly competitive market scenario; the former appears to be a realistic case.

This report evaluates the U.S. and world wheat markets for the 2008-2018 period using the Global Wheat Policy Simulation Model. This analysis is based on a series of assumptions about general economic conditions, agricultural policies, weather conditions, and technological change. Both the U.S. and world wheat economies are predicted to remain relatively healthy for the next ten years. World demand for both common and durum wheat are expected to remain strong. The price levels in 2007 and 2008 will not be maintained in 2009 and future because increased wheat and corn production in 2008 and reduced demand for corn for ethanol production will lower demand and increase supply. World trade volumes of both classes of wheat are expected to expand, but trade...

Grain Contracting Strategies: The Case of Durum Wheat (Summary)
Provedor de dados: 31
Autores: Wilson,   William W.; Dahl,   Bruce L.
One of the impacts of higher prices along with greater volatility in futures, basis and spreads is that there is pressure for greater use of cash contracts for grain. Indeed there has been growth in contracting for a number of competing crops in recent years. There is a wide array of cash contracts with varying terms that pose major strategic alternatives for buyers and the marketing system, particularly as buyers seek to use contracting as an element of risk mitigation. Durum is a crop where many of these issues and challenges are apparent. Durum is more risky than competing crops. There is greater price and yield risk as well as quality risk, and in contrast to competing crops, futures do not exist, cross hedging is poor and forward contracting has been...

The aggregate approach to the evaluation of production oriented expenditure in the United States has consistently shown high rates of return to agricultural research investments. These efforts, while showing the value of agricultural research, are limited in the information they can provide policy and budget decisionmakers. More recently, efforts such as the analysis of four major commodity groups by Bredahl and Peterson and cross sectional studies by Evenson, White, and Havlicek have begun refining the level of analysis to individual regions and states and for specific commodities (Evenson, Bredahl and Peterson, White and Havlicek).

The effectiveness of biosecurity measures at national borders is influenced by the behaviour and levels of involvement of travellers. Involvement is the importance or relevance of an object or situation to an individual. Involvement helps regulate the way in which people receive and process information and thus influences the extent of information searching for decision making, and information processing and persuasion. In this study, we drew on the concept of involvement to investigate the response of individuals to New Zealand biosecurity requirements. A range of people associated with the agricultural and food processing sectors were surveyed using a five item scale of involvement to measure their level of involvement in biosecurity.

Genetically engineered (GE) soybeans first became available to farmers in 1996. Despite the common questions regarding any new crop technology, the new seeds were rapidly adopted. This study examines the characteristics of adopters, as well as yield and weed control cost changes, using survey results from Delaware farmers at the start of the 2000 season. Duration analysis reveals that earlier-adopting farmers had larger farms and tended to use computers for financial management, while regression analysis shows significantly lower weed control costs and, to a lesser extent, higher yields for GE soybeans.

Seasoning a Monopsonic Processor for Collective Action amongst Pepper Producers in Costa Rica
Provedor de dados: 31
Autores: Saenz-Segura,   Fernando J.F.; Schipper,   Robert A.; D'Haese,   Marijke F.C.
The small-scale pepper producers in the El Roble settlement Costa Rica face a monopsonistic market. Only one processing firm is buying the fresh pepper bunches. The processor has all bargaining power to decide on the price paid to the farmers and the quality selection criteria. The rejection rates are high, which is why farmers decided to market their pepper collectively. They started organizing the selection and transport of pepper and entered into group contracts with the firm. We use a non-linear integer simulation model to predict the price level and contractual form (individual or group contracts) which maximises the income of the firm and farmers under three conditions, namely, monopsony (firm holds all bargaining power), monopoly (producers hold all...

This study estimated technical efficiencies on rice farms in Osun State, Nigeria, and identified some socioeconomic factors, which influence productive efficiency. These technical efficiencies were estimated using the stochastic frontier production function approach applied to primary data. A translog production function was used to represent the production frontier of the rice farms. The study showed that the levels of technical efficiency ranged from 29.4% to 98.2% with a mean of 86.6%, which suggests that average rice output falls 13.4% short of the maximum possible level. Therefore in the short run there is scope to increase technical efficiencies on rice farms in the study area. The study also showed that these efficiencies are positively and...

THE EFFECTS OF FARM PRICE SUPPORT POLICIES: HOW LEVEL IS THE PLAYING FIELD FOR GRAIN PRODUCERS IN NAMIBIA?
Provedor de dados: 31
Autores: Akwenye,   P.; Low,   A.
In Namibia historically high levels of support to the commercial farm sector have been reduced in recent years in line with general market liberalisation trends. However some support remains. At the same time more attention has been paid to supporting the previously neglected communal sector. The avowed aim of politicians is to ensure that grain producers in Namibia operate “on a level playing field”. This paper examines to what extent the policy support playing field has been levelled for all major types of grain producer in Namibia. A methodology is introduced for developing a common measure of the effects of price support across grain producers with subsistence and commercial objectives and across scales of operation ranging from 1 hectare to 300...

PROJECTING THE BENEFITS OF GOLDEN RICE IN THE PHILIPPINES
Provedor de dados: 31
Autores: Zimmermann,   Roukayatou; Qaim,   Matin.
Golden Rice has been genetically engineered to produce beta-carotene in the endosperm of the grain. It could improve the vitamin A status of deficient food consumers, especially women and children in the developing world. This paper analyses the potential impacts in a Philippine context. Since the technology is still at the stage of R&amp;D, benefits are simulated within a scenario approach. The health effects are quantified using the methodology of disability-adjusted life years (DALYs). Golden Rice will not completely eliminate the problems of vitamin A deficiency, such as blindness or increased mortality rates. So it should be seen as a complement rather than a substitute for alternative interventions. Yet, the technology will reduce related health...

The Effect of Ethanol-Driven Corn Demand on Crop Choice
Provedor de dados: 31
Autores: Kleiber,   Kandice.
Since the late 1990s, U.S. production of corn ethanol has risen rapidly. In response to high demand, driven in part by rising ethanol production, corn prices and corn production surged in 2007 when corn plantings reached their highest level since 1944. To increase corn acreage, farmers shifted land to corn from other crops or, possibly, returned uncultivated land (e.g., cropland pasture, CRP land) to corn production.   Even before 2007, however, "islands" of relatively high corn prices formed around ethanol plants in the Midwest. Price impacts were usually concentrated around an ethanol plant and ranged between 4.6 cents and 19.6 cents, with an average price increase of 12.5 cents at the plant site. Prices were also affected up to an estimated 68 miles...

An economic model was developed to gain an understanding of price flows in the markets for New York Red Delicious and New York McIntosh apples. Price transmission processes of two apple products, fresh apples and apple juice, are analyzed and compared. Specific emphasis is placed on evaluating price lags and price asymmetry, two factors which complicate the flow of prices between market levels. Results indicate that retail prices of fresh New York Red Delicious apples and fresh New York McIntosh apples respond more fully to wholesale price increases than wholesale price decreases. Results suggest that wholesale prices of fresh New York Red Delicious and fresh New York McIntosh apples are not determined by shipping point price increases and decreases....

This analysis works out the economic implications for variable rate seeding of the corn population response curves estimated by Pioneer Hi-Bred agronomists. Examples are developed for various mixes of low, medium and high yield potential soil, as well as for a range of seed costs and variable rate equipment costs. The strategies analyzed were: variable rate planting using agronomic recommendations for each yield potential zone, variable rate planting using an economic decision rule for each yield potential zone, an information strategy which sets the uniform planting rate at the highest population indicated by agronomic recommendations for any part of the field and a second information strategy which uses an economic decision rule for the whole field based...

Changes in cereal land use and production level in the European Union during the period 1999-2009, focusing on New Member States
Provedor de dados: 31
Autores: Takacs-Gyorgy,   Katalin; Takacs,   Istvan.
The decrease in the area of arable land has further continued in the European Union (EU) since the Millennium. Sustainable development is partially based on the sustainable use of natural resources, which is based on the limitation of land use and on the introduction of different incentives. Previous direct subsidies resulted in increased production. The reform of the Common Agricultural Policy (CAP) has aimed to stop the increase in production, possibly even to decrease production. The objective of this research is to show whether such an effect on land use and on the change of production structure in the EU can be observed. Analyses have shown that agricultural and arable areas have further decreased within land use since the Millennium, continuing the...

Labor Cost and Technology Adoption: Least Squares Monte Carlo Method for the Case of Sugarcane Mechanization in Florida
Provedor de dados: 31
Autores: Iwai,   Nobuyuki; Emerson,   Robert D.; Walters,   Lurleen M.
The prospect of immigration reform has renewed farmers’ concerns of serious labor shortages and cost increases, which may urge highly labor-intensive specialty crop farmers to switch to less-labor-intensive technology. The large-scale mechanization of the Florida sugarcane harvest during the 1970s/80s serves as an historical example of how technologies evolved due to changes in local labor market conditions. We analyze the dynamic decision-making process of sugarcane farmers in the relevant period using net present value (NPV) approach and real options approach (ROA) with least squares Monte Carlo (LSMC).

AN EMPIRICAL EVALUATION OF YIELD PERFORMANCE AND CROSS-CROP YIELD CORRELATION
Provedor de dados: 31
Autores: Goodwin,   Barry K.; Mishra,   Ashok K.
This analysis considers two aspects of yield performance using a large sample of data collected from individual U.S. farms. In the first, observable farm and operator characteristics are related to relative yield perofmance. In general, larger, more diversified farms have higher relative yields. In addition, more intensive use of productive inputs tends to be associated with higher yields. In a second segment of the analysis, we focus on the extent to which yield performance for different crops on a single farm tend to be correlated. Our results suggest that farms in major growing regions tend to have greater correlation of crop yields. In addition, larger, more specialized farms tended to have more consistent yield performance across crops. Implications...

Autores: Crawford,   Eric W.; Howard,   Julie A.; Kelly,   Valerie A.
This paper presents a financial and risk analysis of improved versus traditional maize production technology in Ethiopia, based on yields simulated with the CERES-Maize crop growth model (Schulthess and Ward, 2000). The purpose is to analyze the potential performance of the SG2000/Ministry of Agriculture program technology under less favorable meteorological conditions (rainfall level and distribution), and in areas with lower agroecological potential than those covered by the SG2000/MOA program through 1998. At the time of this study, expansion of the MOA program into lower potential zones seemed likely. Results show that use of fertilizer and improved seed is highly profitable under a variety of assumptions about crop growth conditions, maize prices, and...

This case study focuses on a coffee farmer in Guatemala who, given current low coffee prices, is worried about his ability to maintain the family tradition of coffee production.  He wonders whether the current low prices are just another of the periodic downturns in the volatile coffee market or whether the market is experiencing structural changes that will have long-term implications.  In this case, the farmer is presented with three alternatives, including continuing to produce and market commodity coffee.  The other alternatives involve changes in production and/or marketing practices intended to increase profit margins.

The Controversy of Exchange Rate Devaluation in Sudan: An Economy-wide General Equilibrium Assessment
Provedor de dados: 31
Autores: Siddig,   Khalid H.A.
The international Monitory Fund (IMF) has been working with Sudan since 1997 to implement macroeconomic reforms including a managed float of the exchange rate (EXR). The IMF sees the EXR flexibility as key to safeguard and rebuild foreign exchange reserves and essential to meet the international reserve target in Sudan. However, the authorities in Sudan are concerned that greater exchange rate flexibility could contribute to inflationary pressures. In addition, a review of literature focusing on the exchange rate policies in Sudan reflects huge ambiguity about its outcome.  This calls for additional empirical investigations that provide economy wide assessments of the various possible scenarios that could be adopted in the Sudanese context. Accordingly,...

Autores: Basu,   Jyotish Prakash.
The paper attempts to examine the market integration with the help of cointegration test on the prices of potato of Hooghly district in West Bengal. The analysis has been made at two levels, namely at the level of wholesale markets and at the retail markets. The cointegration test by Johansen and Jeselius (1990) applied to weekly prices of three important potato markets in Hooghly district suggest that the markets are integrated. Our results revealed that price signals and information are transmitted smoothly across the markets. These results have important policy implications. In a situation when potato markets are spatially integrated the government may think of reducing or even withdrawing its efforts to influence the price in the market. The finding of...

This study describes a portion of the grain production and movement patterns in Minnesota.  1999 levels of grain and oilseed production were identified as well as livestock populations in individual counties of the state.  Animal scientists were consulted to ascribe typical consumption levels by the various livestock living in particular counties.  A series of assumptions were required in order to determine the number of additional animals required to maintain sufficient breeding herds and flocks of livestock. Graphs were constructed to present the consumption levels of grain by livestock species in a statewide fashion.  Tables provide detailed data to describe the consumption of feed grains and soybean meal by livestock in each county.  Use of electronic...

Computing Average Per Acre Indemnity Payments for Corn in Iowa
Provedor de dados: 31
Autores: Hart,   Chad E.; Smith,   Darnell B.
This study estimates average per acre indemnity payments for Iowa corn for traditional multiple-peril crop insurance and two new revenue insurance products, Crop Revenue Coverage and Income Protection. Yield and price difference distributions are formed and employed in 1,000 simulation runs.  From these simulations, corn yields for all 99 Iowa countries and futures prices are collected.  These are used to calculate per acre indemnities under the three insurance products.  Income Protection has the smallest per acre indemnities across the state, followed by multiple-peril and Crop Revenue Coverage.  Per acre indemnities are the lowest in northwest Iowa and highest in southeast Iowa.

Agriculture is the most significant contributor to Ethiopia’s economy. Most of the agricultural production is under rainfed conditions and thus extremely sensitive to rainfall variability. Irrigation development, including smallholder irrigation, is used by the Ethiopian Government to attempt to mitigate the effects of rainfall variability. In this study, we look at smallholder irrigation - modern and traditional irrigation systems. A detailed description of the cropping patterns is given. The stochastic frontier production function approach is used to estimate technical inefficiency, and constraints to production are analyzed. Since the traditional system is found to be efficient but on a lower production frontier, the study shows that significant gains...

ORGANIC PEST MANAGEMENT DECISIONS:  A SYSTEMS APPROACH
Provedor de dados: 31
Autores: Park,   Timothy A.; Lohr,   Luanne.
Organic farmers make system-level crop protection decisions that combine complementary insect, disease, nematode, and weed management strategies.  Data from a national survey of U.S. organic farmers were used in a multivariate count data model to identify the farm and regional factors influencing adoption across the linked pest management categories.  The results showed that weed management requires the greatest management effort by organic farmers.  More intensive information-seeking and on-farm experimentation, higher educational attainment, and intensity of commitment to organic farming were positively related to the number of weed control strategies adopted.  Predictions of adoption based on this model and customized to farm and region specifications...

An evolutionary economic perspective on technical change and adjustment in cane harvesting systems in the Australian sugar industry
Provedor de dados: 31
Autores: Brennan,   Lisa E.; Wegener,   Malcolm K.
Australian sugar-producing regions have differed in terms of the extent and rate of incorporation of new technology into harvesting systems. The Mackay sugar industry has lagged behind most other sugar-producing regions in this regard. The reasons for this are addressed by invoking an evolutionary economics perspective. The development of harvesting systems, and the role of technology in shaping them, is mapped and interpreted using the concept of path dependency. Key events in the evolution of harvesting systems are identified, which show how the past has shaped the regional development of harvesting systems. From an evolutionary economics perspective, the outcomes observed are the end result of a specific history.

When the Portuguese and Spanish navigators landed on the American continent in the 15th century, they found cassava being grown by Indians and used to prepare food and alcoholic drinks.  For this reason, cassava can be considered a native American plant which has spread to other regions of the tropics.  Cassava refers to any of several plants which are grown widely in many areas of the tropics for their fresh, starchy, edible root stocks.  It is known as cassava in English speaking regions, as manioc in French speaking areas, as tapioca in English speaking parts of Southeast Asia, as mandioca in Brazil, and as yuca in Spanish speaking regions of South America.  As one of the largest countries in the world, and with the necessity for much greater emphasis...

Wheat Cleaning and its Effect on U.S. Wheat Exports
Provedor de dados: 31
Autores: Haley,   Stephen L.; Leetmaa,   Susan E.; Webb,   Alan J.
This analysis shows that there could be net gains to the U.S. wheat industry if all U.S. export wheat were to be cleaned to a dockage level between 0.35 to 0.40 percent. These results are based on survey results of major importers of U.S. wheat, and a model of world wheat trade. Larger benefits to the U.S. wheat industry would be possible from cleaning only wheat destined to countries that demand higher quality U.S. wheat. However, these gains in export revenue from selling cleaner wheat could be offset if other exporters, especially Canada, responded in ways that would maintain their market share.

ESTIMATING SITE-SPECIFIC NITROGEN CROP RESPONSE FUNCTIONS: A CONCEPTUAL FRAMEWORK AND GEOSTATISTICAL MODEL
Provedor de dados: 31
Autores: Hurley,   Terrance M.; Malzer,   Gary L.; Kilian,   Bernard.
Confirming the precision agriculture hypothesis for variable rate nitrogen applications (VRA) has proven challenging.  To confront this challenge, researchers have begun to use increasingly sophisticated statistical models to estimate and compare site-specific crop response functions.  While progress has been made, we believe it has been hampered by the lack of a clear conceptual framework to guide and motivate the development of appropriate models and methods.  The purpose of this paper was to provide such a framework, while demonstrating its utility.  The framework was used to develop a heteroscedastic, fixed and random effects, geostatistical model to test the potential for VRA to increase nitrogen returns.  The model was implemented with data collected...

Several past studies used time series data to estimate price elasticities of demand for fertilizer or nutrient use on all crops in the United States or by region. In this study, demand functions for nitrogen, phosphorous and potassium applied per acre of corn, wheat and soybeans in the United States were estimated, using a combination of autoregressive least squares and seemingly unrelated regression techniques. The results suggest that the demands for nitrogen, phosphorous and potassium applied to corn are price elastic, while similar responses for wheat and soybeans are price inelastic. Nitrogen and phosphorous applied per acre of corn were found to be positively related to government sponsored acreage diversion. The estimated elasticities could provide...

Autores: Tisdell,   Clement A.; Poirine,   Bernard.
Concentrates on comparing socio-economic aspects of pearl culture in Australia, which mostly relies on the culture of the South Sea pearl oyster P. maxima, with that in French Polynesia which depends on the culture of the black-lipped pearl oyster P. margaritifera.  Australian culture of pearl oysters dates from the 1950s whereas culture of black pearls in French Polynesia dates from the second half of the 1970s.  After briefly outlining the history of pearl culture in Australia and Tahiti, this paper provides an overview of the industry, comparative structure of the industry in Australia and French Polynesia and its technologies.  Socio-economic impacts, especially regional impacts, of the industry are considered.  Market characteristics (such as  prices...

Factors affecting soil conservation decisions of KwaZulu-Natal commercial sugarcane farmers
Provedor de dados: 31
Autores: Ferrer,   Stuart R.D.; Nieuwoudt,   W. Lieb.
Technological information is used to assess KwaZulu-Natal commercial sugarcane farmers' intra-plot (panel) soil conservation relative to requirements of the Conservation of Natural Resources Act of 1983. Findings indicate that farmers consider enforcement of the Act to be unlikely and that 28 percent of farmers surveyed do not meet adequate intra-panel soil conservation standards. Multiple regression is used to estimate models representing intra-panel soil conservation adoption and soil conservation effort. Results show that farmers have greater conservation adoption and effort on their relatively steeper panels and implement soil conservation plans on these panels first. Amongst other factors, education and use of extension information sources are...

Comparing the effects of different approaches to liberalising world grains markets
Provedor de dados: 31
Autores: Hirad,   Hagi; Nelson,   Rohan; Andrews,   Neil; Shaw,   Ian.
The success of the current Doha Round of the WTO negotiations on agriculture will require substantial reform in each of the three areas of market access, export subsidies and domestic support. Substantial improvement in market access for agricultural products will be an essential requirement for achieving a successful outcome. However, the extent of improvement in market access resulting from the current negotiations will largely depend on the form and the approach followed to reduce tariffs and expand tariff rate quotas. In this paper different approaches to expanding market access for grains area analysed using a partial equilibrium model. Simulated scenarios include linear reductions in applied tariffs and expansions in tariff rate quotas, which are...

Autores: Velandia,   Margarita M.; Rejesus,   Roderick M.; Segarra,   Eduardo; Bronson,   Kevin.
This paper develops a management zone delineation procedure based on a spatial clustering approach and evaluates its economic impact for the case of Texas cotton production. The results show that there is potential economic value in using a spatial approach to management zone delineation, but its value critically depends on the cost of collecting soil test information needed to delineate those zones.

Autores: Brandao,   Elizabeth Santos; McCarl,   Bruce A.; Schuh,   G. Edward.
An analysis is done on the potential effects of several improved cropping practices in a subsistence agricultural farming system along with analyses of other development options.  The farming system is modeled as a linear programming model.  The problem involves mixture of perennials and annuals, sharecropping provisions and risk.  The practices are found to have differential effects on the distribution of income between the landlords and tenants, marketable surplus and on farm employment.

TECHNICAL EFFICIENCY OF UPLAND RICE PRODUCERS IN SOUTH WESTERN UGANDA
Provedor de dados: 31
Autores: Jude,   Asiimwe. K.
Uganda’s rice demand has been on an increase due to increasing population, urbanization and changing consumer preferences. The resulting effect has been increased importation of rice into the country consequently straining foreign exchange accounts. Insufficiency in the rice supply is related to the low national average yield of 1.5t/ha. New upland rice varieties that are high yielding have been introduced in the country to improve national supply, save wetlands, fight food insecurity and improve incomes of the rural poor. This study was conducted in South Western Uganda in the districts of Bushenyi and Rukungiri. It examined whether farmers were technically efficient in input use to generate the required output levels and the farm specific factors that...

Economic Aspects of the California Nursery and Floral Industry, 2001–2009
Provedor de dados: 31
Autores: Carman,   Hoy F.
California’s nursery and floral industry is the largest in the United States with a farm value for product sales totaling $3.78 billion in 2009. When floral and nursery product sales are combined, the industry ranks second among all California agricultural products, following the dairy industry. Production is in 55 of California’s 58 counties, although 16 counties account for more than 87% of the value of production. San Diego County dominates the industry with annual sales over $1 billion in 2007, 2008, and 2009. Since its 2008 and 2009 sales increased while California’s statewide sales decreased, San Diego County increased its share of California sales from 26% in 2007 to 30.3% in 2009.  California is the largest single retail market for lawn and garden...

The aim of this paper is to set-up the algorithm for determining the degree of workability of the soil, to help the owners of family farms to plan working hours of agricultural machines, i.e. with the machine park management. The plans, which would be made by use of these algorithms and based on the accurate information of the cultivation conditions, would result in the appropriate use of time and capacity of the agricultural machines. In some sectors, such as agriculture or certain industries, chance that certain event occurs plays a very important role. The influence of random events, however, can be significantly reduced if decision makers are counting on them, reveal their nature and gather as much information about them as possible.

Deciding how to coordinate activities can be a challenge posed in any marketing chain. This case involves an agricultural cooperative that has focused entirely on marketing raw sugar cane for additional refinement. Recent dramatic shifts in the sector have caused the members of the cooperative to consider building a facility that will process the raw sugar cane. In so doing, the cooperative can consider using the spot market, using contracts, vertically coordinating, or vertically integrating. This case study of Louisiana Sugar Cane Products, Inc. is a unique, real-life case that can be widely used in marketing and cooperatives courses.

Autores: Koo,   Won W.; Taylor,   Richard D.
This report evaluates the U.S. and world wheat markets for the 2005-2015 period using the Global Wheat Policy Simulation Model.  This analysis is based on a series of assumptions about general economic conditions, agricultural policies, weather conditions, and technological change.  Both the U.S. and world wheat economies are predicted to improve for the next nine years.  World demand for both common and durum wheat are expected to grow faster than world production, resulting in gradual increases in prices of the wheat varieties.  However, the current higher price levels in 2006 are due to weather conditions and will not be maintained, as production is expected to return to normal levels in 2007.  World trade volumes of both classes of wheat are expected...

Reducing Crop Nutrient Applications:  The Yield Reserve Program
Provedor de dados: 31
Autores: Metcalfe,   Todd; Bosch,   Darrell J.; Pease,   James W.
A proposed Yield Reserve Program designed to compensate farmers for any reduced yields resulting from reduced nitrogen (N) application rates below recommended rates is evaluated.  Assuming that farmers currently follow extension recommendations for applying N, Yield Reserve Program participation reduces expected net revenue by $10 to $13/ha.  The Yield Reserve Program reduces expected net revenue by $17 to $20/ha for farmers who apply N to maximize expected net revenue.  Farmers’ costs of participation increase with lower probabilities of inadequate rainfall and higher corn prices and decline with higher N prices.  The Yield Reserve Program can significantly reduce N applications to cropland, which may reduce N content of surface waters, but the costs to...

Measuring the Consistency of Phytosanitary Measures
Provedor de dados: 31
Autores: Bigsby,   Hugh R.
The paper presents a model for quantifying quarantine-related phytosanitary measures by combining the two basic components of pest risk assessment, probability of establishment and economic effects, into a single management framework, Iso-Risk. The model provides a systematic and objective basis for defining and measuring acceptable risk and for justifying quarantine actions relative to acceptable risk. This can then be used to measure consistency of phytosanitary measures. The Iso-Risk framework is applied using a database of USDA phytosanitary risk assessments. The results show that the USDA risk assessment system produces assessments that are not consistent across a range of intermediate values for consequence or likelihood of occurrence.

MOVING FROM UNIFORM TO VARIABLE FERTILIZER RATES ON IOWA CORN: EFFECTS ON RATES AND RETURNS
Provedor de dados: 31
Autores: Babcock,   Bruce A.; Pautsch,   Gregory R.
This study develops a model based on the yield potential of various soil types in 12 Iowa counties to estimate the potential value of switching from uniform to variable fertilizer rates. Results indicate modest increases in the gross returns over fertilizer costs, ranging from $7.43 to $1.52 per acre. The net profitability of variable-rate technology (VRT) is sensitive to the per acre costs of moving to a VRT program. Under the assumptions of the model, applying variable rates would increase yield by 0.05 to 0.5 bushels per acre, and would reduce fertilizer costs by $1.19 to $6.83 per acre.

This study focuses on development of agricultural best management practices (BMPs) for potato production areas in Northeast Florida, and presents the results of the initial situation assessment. BMP implementation is the primary strategy used by agencies and farmers to improve the efficiency and to ensure environmental sustainability of agricultural production. Although BMPs are defined as “economically feasible” and “cost-effective”, economic analysis conducted as a part of BMP development has been limited, leaving the room for disagreement about economic impacts of specific BMPs. As a part of the situation assessment, we used interviews, group discussions, a survey, and a field trip to collect information about farmers’ production practices and to...

Provedor de dados: 31
Autores: Ludena,   Carlos E.; McNamara,   Kevin T.; Hammer,   P. Allen; Foster,   Kenneth A.
Increased domestic concentration and international competition in the floricultural industry are forcing growers to improve resource management efficiency. Cost management and cost accounting methods are becoming key tools as growers attempt to reduce costs. These tools allow growers to allocate costs for each crop, increasing their greenhouse planning abilities. Growers have a relative high degree of risk due to potential crop and market failure. Individual growers have different tolerance for risk and risk bearing capacity. Growers need a cost accounting system that incorporates production and market risk, a system that allows them to make informed business decisions. The research reported in this paper developed a greenhouse budgeting model that...

A theoretical model based on opportunity cost and expected utility principles establishes linkages between the likelihood of prevented planting claims in crop insurance, existing share leasing arrangements and internal farm business structures.  Results of probit estimation procedures indicate that simpler internal business structures and a more dominant farmer-tenant leasing position can increase the probability of submitting a prevented planting claim.

Adoption of New Seed Varieties Under Production Risk: An Application to Rice in Iran
Provedor de dados: 31
Autores: Bakhshoodeh,   Mohamad; Shajari,   S.
This paper focuses on linkage between new rice seed varieties and production risk and also factors affecting adoption of these varieties in Iran. Farm-level data were collected from a sample of 154 rice farms located in two major districts of Fars province in Southern Iran for 2001-02. The risk-premium associated with the use of seed is estimated following by analyzing a moment-based production risk approach. The results show that the risk premium increases with new seed varieties in the lack of appropriate production conditions implying that new seed varieties is a riskincreasing input and involves a higher cost of risk. However, under suitable production conditions, the cultivation of new rice varieties on average ensures greater yield and at the same...

Hurricanes and Possible Intensity Increases: Effects on and Reactions from U.S. Agriculture
Provedor de dados: 31
Autores: Chen,   Chi-Chung; McCarl,   Bruce A.
Hurricanes have caused substantial damage in parts of the U.S. Damages are increasing, perhaps as part of a natural cycle or perhaps in part related to global warming. This paper examines the economic damages that hurricanes cause to U.S. agriculture, estimates the increased damage from an increase in hurricane frequency/intensity, and examines the way that sectoral reactions reduce damages. The simulation results show that hurricanes and associated adjustments cause widespread damage and redistribute agricultural welfare. We find that crop mix shifts of vulnerable crops from stricken to nonstricken regions significantly mitigate hurricane damages.

Impact of global warming on Chinese wheat productivity
Provedor de dados: 31
Autores: You,   Liangzhi; Rosegrant,   Mark W.; Fang,   Cheng; Wood,   Stanley.
Climate change continues to have major impact on crop productivity all over the world. While many researchers have evaluated the possible impact of global warming on crop yields using mainly indirect crop simulation models, there are relatively few direct assessments on the impact of observed climate change on past crop yield and growth. We use a 1979-2000 Chinese crop-specific panel dataset to investigate the climate impact on Chinese wheat yield growth. We find that a 1 percent increase in wheat growing season temperature reduces wheat yields by about 0.3 percent. This negative impact is less severe than those reported in other regions. Rising temperature over the past two decades accounts for a 2.4 percent decline in wheat yields in China while the...

An Economic Evaluation of Investment on Aonla (Emblica officinalis G.) in Gujarat
Provedor de dados: 31
Autores: Gondalia,   V.K.; Patel,   G.N.
The economic viability of aonla plantation in Gujarat has been studied through a sample of 120 aonla growers spread over 12 selected villages of the Kheda and Anand districts for the agricultural year 2003-04. It has been found that establishment of aonla orchard involves high investment, but the annual net returns are also quite high, after the third year of plantation. The values of economic parameters, viz. NPV, BCR, IRR and PBP have been found to be Rs 652652, 5.25, 65.03 per cent and 55 months, respectively at 10 per cent discount rate. Under varying cost and return situations, values of all these feasibility parameters have satisfied the acceptance rules for the investment proposition. It has confirmed the economic viability, stability and certainty...

THE PROFITABILITY ANALYSIS OF BEAN PRODUCTION IN NICARAGUA
Provedor de dados: 31
Autores: Ishikawa,   Yuki.
In Nicaragua, government policies have historically favored agro-export industries, such as coffee, cotton and sugar. In the early- 1990, the government began to implement policies favoring small-scale farmers cropping beans and maize. However, bean yields are still low. Since 1990, few studies have focused on Nicaragua's second most important crop, beans.  This study analyzes record-keeping (RK) data collected from 15 small bean farmers located in the Carazo and Masaya regions. The study assesses costs and patterns of input and labor use and the profitability of bean production. Five farmers among the sample grew traditional bean varieties and ten modem farmers cropped improved bean varieties.  The study found that the modem farmers intensively applied...

Optimal strategies for regional cultivar testing
Provedor de dados: 31
Autores: Brennan,   John P.; Kingwell,   Ross S.; Thomson,   Fiona M.; Cullis,   Brian R.
In undertaking cultivar trials, the variability of the response of the cultivars to the different environments in which they are grown introduces the possibility of release errors and non‐release errors in the decisions made on the basis of the trial results. In this article a model is developed that accounts for the economic costs of those errors as well as the costs of operating the trials, and enables the features of the optimal cultivar testing program to be identified. The model is illustrated by application to wheat cultivar trials in central and southern NSW.

CAN AGRICULTURAL PRODUCTION IN THE MARGINAL LANDS CONTRIBUTE TO IMPROVING FOOD SECURITY IN THE SAHELIAN AFRICAN COUNTRIES: AN EVIDENCE FROM THE BAS-FOND RICE PRODUCTION IN MALI
Provedor de dados: 31
Autores: Dimithe,   Georges; Bernsten,   Richard H.; Staatz,   John M.; Sanogo,   Ousmane; Coulibaly,   B.S.; Simpara,   M.
To improve national food security, successive Mali governments have always focused on expanding and intensifying production in the government-managed irrigation schemes (Office du Niger), which account for about 50% of domestic rice production.  Because the cost of expanding and  rehabilitating those schemes is high, the government is looking for complementary cost-effective ways to achieve this goal.  The government could increase domestic rice supply by investing in improving the farmer-managed inland valley swamps.  Although the government has paid little attention to those marginal lands, farmers have been growing rice in these areas using traditional technologies.  This paper used data from a survey of 334 bas-fond farmers and secondary data to...

INTERTEMPORAL DECISIONS OF FARMERS’ RISK MANAGEMENT: A DYNAMIC OPTIMIZATION WITH GENERALIZED EXPECTED UTILITY
Provedor de dados: 31
Autores: Du,   Wen; Wang,   H. Holly.
In this paper we attempt an intertemporal study of risk management decisions for wheat growers in the Pacific Northwest. We apply a generalized expected utility model (GEU) to examine the farmers’ optimal choices of hedging ratios and crop insurance coverage levels in the presence of government payment programs in a multi-period production environment. A stochastic trend model is used to identify the long-term time series patterns of annual wheat yields, cash prices, and futures prices from two counties in Washington. The fitted models are then used as the base for yield and price simulation over the next five years. The stochastic dynamic optimization problem is solved numerically based on simulated data. The optimal solutions indicate that the GEU model...

The Maize Green Revolution in Kenya Revisited

Autores: De Groote,   Hugo; Owuor,   George; Doss,   Cheryl R.; Ouma,   James Okuro; Muhammad,   Lutta; Danda,   Milton Kengo.
The maize green revolution, which increased maize yields through the use of improved varieties and fertilizer, has stalled since the mid-eighties in Kenya. This paper examines whether the stagnation of yields continued in the 1990s in spite of the implementation of the maize liberalization policies by the Kenya Government. Analysis of farm level surveys from 1992 and 2002 indicates slight increases in the use of improved maize varieties and fertilizer, but a substantial decrease in the intensity of fertilizer use. The econometric analysis suggests that the intensity of fertilizer use has a major effect on yield. The use of improved maize varieties, however, did not affect yield, suggesting that there are local varieties for some areas that do as well as...

This study used the 2005 ERS CEAP-ARMS data for corn production to first compare key operator, field, farm, economic, and environmental characteristics of conservation program participants with non-participants, by farm-size class.  We then estimate a cost-function based technology adoption model of producer decisions regarding the allocation of field-level acres between corn production and infield and perimeter-field conservation structures to examine how these conservation choices differ between program participants and non-participants, while accounting for differences in other field, farm, and environmental factors.  Our null hypothesis is that the average conservation structural practice acres across U.S. corn acres supplied by growers participating...

The Impact of the E.coli Spinach Outbreak on Acreage Decisions Under Uncertainty
Provedor de dados: 31
Autores: Mohr,   Belinda Acuna.
This article quantifies the effect of the 2006 food-borne illness spinach outbreak on harvested acreage for the fresh spinach market.  In September 2006, fresh spinach contaminated with E. coli O157:H7 caused hundreds of consumer illnesses across the U.S. and a few deaths.  The outbreak was detrimental to the spinach industry causing a significant decrease in the demand for spinach.  Spinach growers were prohibited from harvesting spinach until more was known about the contamination.  According to the Census of Agriculture, harvested spinach acreage for the fresh market fell by 17% from before the outbreak.  Due to the unanticipated effects resulting from the outbreak, farms potentially decreased their acreage of fresh market spinach to reduce profit...

Crop genetic resource policy: the role of ex situ genebanks
Provedor de dados: 31
Autores: Wright,   Brian D.
The world-wide capacity of genebanks for ex situ conservation of crop genetic resources has increased greatly since the 1970s, improving the access of crop breeders to landraces and wild and weedy relatives. But utilization of genebank resources has not kept pace. The set of popular cultivars in major crops is typically rather small, and their ancestry encompasses only a fraction of the genetic diversity currently available in other cultivars. Discussions of farmers' rights that focus on compensation for current incorporation of farmers' varieties in new cultivars have diverted attention from the question of why so little of the newly accessible genetic diversity is currently being utilized by public and private breeders. To optimize the future provision...

Adoption and impacts of zero tillage as a resource conserving technology in the irrigated plains of South Asia
Provedor de dados: 31
Autores: Erenstein,   Olaf; Farooq,   Umar; Malik,   R.K.; Sharif,   Muhammad.
The recent stagnation of productivity growth in the irrigated areas of the Indo-Gangetic Plains of South Asia has led to a quest for resource-conserving technologies that can save water, reduce production costs and improve production. The present synthesis of two detailed country studies confirmed widespread adoption of zero tillage (ZT) wheat in the rice-wheat systems of India’s Haryana State (34.5% of surveyed households) and Pakistan’s Punjab province (19%). The combination of a significant “yield effect” and “cost-saving effect” makes adoption worthwhile and is the main driver behind the rapid spread and widespread acceptance of ZT in Haryana, India. In Punjab, Pakistan, adoption is driven by the significant ZT-induced cost savings for wheat...

Rice Price Stabilization in Madagascar: Price and Welfare Implications of Variable Tariffs
Provedor de dados: 31
Autores: Dorosh,   Paul A.; Minten,   Bart.
Given the large share of major staples in the budgets of the poor, governments in many developing countries intervene in food markets to limit variation in the prices of staple foods. This paper examines the recent experience of Madagascar in stabilizing prices through international trade and the implications of adjustments in tariff rates. Using a partial equilibrium model, we quantify the overall costs and benefits of a change in import duties for various household groups, and compare this intervention to a policy of targeted food transfers or security stocks.

TESTING DYNAMIC SPECIFICATIONS FOR IMPORT DEMAND MODELS: THE CASE OF COTTON
Provedor de dados: 31
Autores: Arnade,   Carlos Anthony; Pick,   Daniel H.; Vasavada,   Utpal.
Error correction models impose few prior restrictions on dynamic model specification and allow the data to determine model structure. Despite this obvious advantage, few applications have adopted the error correction model to explain trade flows. An error correction model of cotton import demand is estimated for France, Japan, and Hong Kong. A variety of tests are applied to determine the dynamic structure of the model. We find the most general models are those that best fit the data for cotton import demand. Long-run elasticities from these general models are significantly different than elasticities derived from a comparable static model.

The East African country of Uganda might not be thought of as the location of a viable, growing dairy industry. However, Uganda recorded a threefold increase in milk production from 1991 to 2004. While Uganda's dairy industry faces important challenges, the industry possesses advantages that can lead to further increases in milk production if additional, profitable markets can be found for Uganda's milk and dairy products. A major advantage possessed by Uganda's dairy industry is a favorable climate for milk production. Uganda's farmers also have demonstrated a willingness to accept new technologies that can increase milk production. The biggest challenges facing the industry are those associated with poor milk quality and pronounced seasonality of milk...

Decades of Soviet rule have left a heritage of environmental and social problems in Central Asia. The demise of an entire ecosystem at unprecedented pace, the "Aral Sea Syndrome", is the most prominent of the undesired outcomes of the focus on agricultural production that has dominated land and resource use and continues till today. The international outcry over this ecological crisis has delegated other – and maybe more urgent – problems to a second pane. Rural livelihoods are rapidly deteriorating, unemployment is high, and rural poverty widespread. Ecological aspects, although strongly affecting everyday life in rural areas – such as water and soil salinity and environmental pollution – are not the fore most concern to the local population, as the...

FARMING FOR ETHICS: AN EXAMINATION OF THE ETHICAL CHALLENGES OF MISSOURI CORN AND SOYBEAN PRODUCERS
Provedor de dados: 31
Autores: James,   Harvey S., Jr.
Interviews with Missouri corn and soybean farmers reveal what farmers feel are the most important ethical challenges in agriculture. In contrast to the literature, which characterizes ethical challenges in term of philosophical debates about soil conservation, the use of pesticides and genetically modified seeds, or the treatment of animals, for instance, this research finds that farmers perceive ethical challenges in behavioral terms. The reason is rooted in the industrialization of agricultural production, which creates tensions for farmers between doing what they believe to be right and doing what they feel they must in order to survive.

The impact of reforming the Common Agricultural Policy on the sustainability of the irrigated area of Central Italy. An empirical assessment by means of a Positive Mathematical Programming model
Provedor de dados: 31
Autores: Cortignani,   Raffaele; Severini,   Simone.
The Common Agricultural Policy (CAP) is a major driver of the environmental and social sustainability of the agriculture in the European Union (EU). Under the 2003 CAP reform, most direct payments to agricultural producers were decoupled from production. This work assesses the possible impact of the CAP reform on the sustainability of an irrigated area of Central Italy with particular attention being paid to decoupling. The analysis has been conducted using the Positive Mathematical Programming (PMP) method that directly estimates the cost function parameters by imposing the first-order conditions of the farm model under consideration. The analysis assesses the impact of the CAP reform on farm cropping patterns, water and chemical use, labour use and...

The primary objective of this research was to measure the extent of market integration between major surplus and deficit maize markets in Mozambique namely, Chimoio-Maputo, Chimoio-Beira, Ribaue-Nampula, and Mocuba-Nampula. To achieve this objective, Threshold Vector Autoregressive models were applied. The choice of the model was motivated by unobservable transaction costs and the import ant influence that their presence may exert on equilibrium spatial price relationships. The following are some of the major findings of the study. Firstly, threshold values (i.e. estimates of transaction costs) are found to be correlated positively with distance and inversely with the condition of the roads connecting markets. Secondly, market integration analysis revealed...

THE OPTIMAL CHOICE OF RESIDUE MANAGEMENT, CROP ROTATIONS, AND THE COST OF SOIL CARBON SEQUESTRATION
Provedor de dados: 31
Autores: Choi,   Suk-Won; Sohngen,   Brent.
This paper develops a dynamic model of land, crop, and residue management choices in a typical Midwestern farm region. Carbon renting policy is implemented with alternative assumptions about relative crop prices. Model results show following results. First, crop choice between corn and soybean within a scenario does not appear to be sensitive to carbon prices. Second, residue management and carbon storage depend on crop prices and total carbon storage in soil is the greatest when more land is maintained in soybean. Third, there would be 4-7% increase in carbon per hectare with $3 per ton carbon price, 13-23% increase with $10 per ton carbon price, and 31-55% increase in carbon storage with $40 per ton carbon price.

The state enforcement mechanism is weak and cannot protect the individuals or eventually back the collective decisions. The above problem is investigated in the case of irrigation in Bulgaria where water usage declined by nearly 85% during the period of transition. In addition, large parts of the existing canal systems were abandoned. Three groups of institutional options are investigated in the paper: improvement of the local level...

INTERACTION EFFECTS OF PROMOTION, RESEARCH, AND PRICE SUPPORT PROGRAMS FOR U.S. COTTON
Provedor de dados: 31
Autores: Beach,   Robert H.; Murray,   Brian C.; Piggott,   Nicholas E.; Wohlgenant,   Michael K.
Many agricultural commodities have industry-funded generic promotion and/or research (“"checkoff”") programs designed to improve the economic performance of producers.  To determine the effectiveness of these programs, the net benefits to producers attributable to activities funded by the checkoff must be separated from those due to other factors influencing commodity markets.  One such factor that is very important in many agricultural commodity markets is the effect of government programs.  However, studies evaluating the returns to checkoff programs often do not explicitly discuss the impact of pre-existing distortions caused by federal farm programs.  Because the distortions caused by farm programs can be quite large, this omission can lead to...

How Much Do Decoupled Payments Affect Production? An Instrumental Variable Approach with Panel Data
Provedor de dados: 31
Autores: Weber,   Jeremy G.; Key,   Nigel D.
Agricultural support payments that cause no or minimal production distortions are exempt from World Trade Organization restrictions. If and how much decoupled payments, such as direct payments in the U.S., affect agricultural production remains an open empirical question with implications for policy. We use multiple years of the Census of Agriculture to estimate the aggregate supply response to changes in direct payments. To identify an exogenous source of variation in payments we exploit a provision of the 2002 Farm Act that departed from previous policy by making oilseeds eligible for direct payments, thus increasing payments to areas that historically produced more oilseeds. Using a sample of ZIP codes that accounts for more than eighty percent of the...

ECONOMIC CONTRIBUTION OF THE WHEAT INDUSTRY TO NORTH DAKOTA
Provedor de dados: 31
Autores: Bangsund,   Dean A.; Leistritz,   F. Larry.
The purpose of this study was to measure the economic contribution of the wheat industry to the North Dakota economy.  Wheat is produced in all areas of the state; however, production is concentrated in the Red River Valley and in the northern third of the state.  Wheat production (spring, durum, and winter wheat) in North Dakota averaged about 9.1 million planted acres and 275 million bushels annually from 2001 through 2003.   Direct impacts (in-state expenditures and returns) from wheat production averaged $126.50 per acre or $1.14 billion annually from 2001 through 2003.  Direct impacts from handling wheat at North Dakota elevators were estimated at $32 million annually.  Transportation of wheat to both in-state and out-of-state destinations was...

Sugar market is one of the most protected markets for agricultural products world wide. In almost every sugar producing country the sugar market is regulated in some way. With an increasing liberalization of agricultural trade in the "Millennium Round" of the WTO trade negotiations, the question of international competitiveness is of increasing importance. Based on empirical studies, in this article the competitiveness of sugar production in the most important sugar producing countries is analysed, including the whole production process from beet or cane production in the field to sugar processing in the factory. Special emphasis is focussed on the different location factors and their influence on competitiveness, so that finally, conclusions can be drawn...

Analysis of the Soybean-to-Corn Price Ratio and its Impact on Farmers' Planting Decision-Making in Indiana
Provedor de dados: 31
Autores: Ubilava,   David.
In Indiana agricultural land is used mostly for corn and soybean harvesting. Rotated corn is a common practice, but in recent years, essentially due to the "ethanol boom" and increased profitability of corn production, many farmers have switched to continuous corn. Corn price increase affects the soybean-to-corn (STC) ratio, however, it is hypothesized that over time market effects will be felt, and return the ratio to its stable range. The threshold autoregressive model is used to analyze the monthly time series of STC ratio in Indiana. Results suggest that exogenous shocks will not have permanent effect on the STC price ratio, but will require, however, a reasonably long time to die out.

A Methodology for Measuring Potential Benefits from Drought-Oriented Research in Nebraska
Provedor de dados: 31
Autores: Leholm,   Arlen G.; Supalla,   Raymond J.; Vollmar,   Glen.
The growth in agricultural productivity and significance of science and technology in contributing to this growth has been well documented by Bredahl, Cline, Evenson (1967), Griliches (1964), and Peterson. The results of these studies generally indicate that over the past several decades, investment in agricultural research has paid off with relatively high rates of return. Most of this previous work, however, has been directed at estimating returns to aggregate agricultural research in an ex post sense at the national level and does not address the question of potential future returns to research at a state or regional level (Norton). Thus, a particular need exists to develop a methodology for evaluating the potential returns to specific types of...

DYNAMIC ECONOMIC ANALYSIS OF A RESIDUE MANAGEMENT SYSTEM IN COTTON
Provedor de dados: 31
Autores: Paudel,   Krishna P.; Lohr,   Luanne.
Residue management system (RMS), comprised of no till cultivation, a winter cover crop, and poultry litter, could be an alternative to existing management system in cotton production in the Georgian Piedmont.  We compare the productivity and profitability of RMS with the current system over time, focusing on the role of organic matter.  Using dynamic bioeconomic modelling technique, we show that the net return and land value difference between these two systems increase as the terminal period increases.  We conclude that if financial and capital markets based on organic matter work efficiently, farmers will choose RMS in cotton production.

AN ECONOMETRIC ANALYSIS OF THE SUPPLY OF MAIZE IN LESOTHO
Provedor de dados: 31
Autores: Phoofolo,   Marabe.
Lesotho is largely agrarian.  More than 90 percent of the Basotho population lives in rural areas.  Agriculture provides an important source of income for over 50 percent of the rural population and is the largest contributor to GDP.  Apart from migrant labour in the Republic of South Africa (RSA) and limited work in administration and commerce in the few urban centers, there are few employment opportunities other then agriculture. Under production of maize coupled with a growing population has lead to great shortages of maize in Lesotho.  The hunger and nutritional problems associated with the maize shortage problem prompted the Government of Lesotho to set out self-sufficiency goals, which if met would help solve the maize shortage problem.

U.S. Peanut Markets Adjust to Policy Reform

Autores: Dohlman,   Erik; Hoffman,   Linwood A.; Young,   C. Edwin.
With the recent (2002) elimination of the longstanding "marketing quota" system that supported domestic peanut prices at well above world levels, the U.S. peanut sector is in the initial stages of adjusting to a more uncertain, market-oriented environment. At the aggregate level, some early indications are that the adjustment process for U.S. peanut farmers has been difficult, resulting in deep losses of revenue and a rapid exit from peanut production by some producers. In 2003, the value of U.S. peanut production was down 30 percent and prices fell by nearly 25 percent compared with 2001. U.S. peanut planted acreage is at its lowest since 1915, and planted acreage has declined sharply in several important peanut producing States-55 percent in Virginia and...

This paper reviews the structure and performance of the sorghum and millet seed sector in Mali. The Sahel is the origin of pearl millet and sorghum, seed selection and management of these crops is embedded in local cultures, and most producers of these crops are subsistence oriented. Despite seed sector reform, no certified seed of these crops is sold in local markets and farmers prefer to rely on themselves or each other for seed. The dominant source of certified seed is the national seed service. Certified seed is multiplied by contracted farmers and seed producer groups, and supplied to farmers through farmers’ associations, development organizations, and extension services. The informal sector supplies farmers with non-certified seed directly and...

Farmers’ supply responsiveness planting rice in Jambi Province was estimated using Meta- Profit analysis function. The objective of study is to analyze rice farmers’ supply response. Research was conducted in Jambi Province in the year of 2010. Result showed that farmers’ profit planting rice increased because its price increased. Furthermore, its share decreased when its labour wage increased. This implied to farmers to plant rice because rice was relatively more profitable than other plants. The result showed that farmers tended to pushed risk in planting decision. As expected that irrigation index was also the important significant factor. Following it found that its profit planting rice increased in wet season. This results were consistent with the...

Autores: Elmer,   Nicole A.; Thurow,   Amy Purvis; Johnson,   Jason L.; Rosson,   C. Parr, III.
The Dixit-Pindyck model was applied to examine the hypothesis that uncertainty associated with grapefruit production costs and returns is an important determinant of Texas grapefruit growers' investment behavior.  Freezes, price variability, and the effects of expanded trade were analyzed as risk factors.  An investment decision rule based on a net-present value calculation would approve a 25-year commitment to a 20-acre grapefruit grove, given a 6-percent discount rate.  The modified hurdle rate, calculated using an ex ante version of the Dixit-Pindyck model, is 24 percent.  The major source of the risk borne by Texas grapefruit investors is from freezes, rather than from expanded trade.

A Dynamic Optimal Crop Rotation Model in Acreage Response
Provedor de dados: 31
Autores: Cai,   Ruohong; Bergstrom,   John C.; Mullen,   Jeffrey D.; Wetzstein,   Michael E.
This paper presents a dynamic crop rotation model that shows how crop yield and price volatility could impact crop mix and acreage response under crop rotation considerations. Specifically, a discrete Markov decision model is utilized to optimize producers’ crop rotation decision within a finite horizon. By maximizing net present value of expected current and future profits, a modified Bellman equation helps develop optimum planting decisions. This model is capable of simulating crop rotations with different lengths and structures. Specifically, the corn-soybeans rotations were simulated using the crop rotation model.

They demonstrate that voluntary agreements can create value for both regulators and firms. Little has been written, however, that analyzes various voluntary arrangements in the winegrowing sector. The evidence accumulated from other sectors indicates that efforts in the winegrowing sector may be following an appropriate path for attaining management objectives. The California Sustainable Winegrowing Practices (SWP) project indicates a number of strategies that may be useful in developing voluntary agreements in other regions. The...

Improving Irrigated Agriculture: How Far Can We Go?
Provedor de dados: 31
Autores: Meyer,   Wayne S.
The last decade has seen the nexus between increasing world population and the area of irrigated land broken, indicating that further population will need to be fed by improved water productivity rather than through increased irrigated area. But how much improvement is possible? This paper systematically considers irrigated agriculture from the plant through to a catchment, and from production and natural resource use perspectives. While there is some evidence of improvement in transpiration productivity (yield per unit of transpired water) of our common irrigated crops, it seems we have reached the limit of potential improvement. Opportunity still exists to increase economic yield while containing seasonal water use through manipulation of vegetative and...

In this paper we analyse the technical efficiency of cotton farmers in the Punjab Province in Pakistan. Technical efficiency is measured relative to a stochastic frontier production function (SFPF). The estimated model includes a function in which technical efficiency is made an explicit function of firm specific factors (involving the levels of education and experience of farmers and other factors). For the purpose of analysis, survey data was collected for the 1996-97 season. Analysis is done on a district basis and the mean technical efficiencies obtained are 76, 78, 77 and 83 per cent for the districts of Arifwala, Bahawalpur, Multan and Rahim Yar Khan respectively. This study suggests that there is considerable room for productivity gains for the...

Farm retail marketing or farmer-to-consumer direct marketing is an important outlet for many New York vegetable products. Marketing direct to consumers takes special skills and abilities on the part of marketers, and also requires a favorable location with respect to land resources and local markets. Since many farmers and direct market managers lack the resources and experience to compete with supermarkets, it is important for direct marketing operators to differentiate themselves from the mass marketers. The goal of this study was to analyze the effectiveness of direct marketing activities and marketing strategies used by New York vegetable farms.

UNDERWRITING ASSISTANCE TO THE AUSTRALIAN WHEAT INDUSTRY - AN APPLICATION OF OPTION PRICING THEORY
Provedor de dados: 31
Autores: Bardsley,   Peter; Cashin,   Paul.
For the ten crop seasons 1979-80 to 1988-89, returns to producers in the Australian wheat industry were underwritten by a government-guaranteed price floor. Similar schemes operate in other rural industries (dairy, apples and pears, dried fruits). Although the underwriting provisions have only been triggered once (in the 1986-87 season), the provision of this scheme has acted to reduce the risk normally associated with returns to producers of wheat in all years of its operation. This reduction in risk has been granted free-of-charge by the Commonwealth Government.  The guaranteed price can be viewed as a put option taken out by the Government on behalf of growers - it gives growers the option to sell to the Australian Wheat Board at this floor price. The...

The increase of living standard requires ever more energy, despite energy saving measures. Domestic growth was 100 PJ between 2000 and 2006, and 77% of the total utilization was imported (Hungarian Central Statistical Office, 2008). Sustainability was endangered not only in our energy and commerce policy. Our domestic natural conditions are suitable for plant production; however, the stagnation of the domestic population and decreasing livestock numbers restrict inland marketing. Therefore, significant surpluses from year to year had to be stored and sold abroad, and the fact that the interventional purchase of corn and the expected stringent new EU regulation of the sugar beet sector, make the strategic significance of these branches uncertain.

Para tanto, utilizou-se o Índice de Vantagem Comparativa Revelada (IVCR). Verificou-se que o Brasil como um todo não possui vantagem comparativa para exportação de arroz. Por outro lado, entre os estados produtores, o Rio Grande do Sul se mostrou competitivo internamente em todo o período considerado e, em 2005, também como exportador. Santa Catarina, Mato Grosso e Goiás apresentaram competitividade apenas internamente para alguns dos anos analisados. Mato Grosso do Sul não se mostrou competitivo em nenhum dos anos considerados.----------------------------------------------This paper’s...

The capability of personal values and guanxi to reduce negative external effects of Chinese agriculture
Provedor de dados: 31
Autores: Weber,   Daniela; Bergmann,   Holger.
China is the world’s largest producer and consumer of agricultural products, but the intensive agriculture contributes in a remarkable manner to environmental problems. Since environmental protection has recently become a popular issue in China, the government attaches great importance to the formulation of laws and regulations. Accordingly, China faces serious challenges inter alia in the accomplishment of effective agricultural trainings, environmentally sensitive farming and especially in the farmers’ willingness to adopt optimized farming approaches. In order to promote a sustainable adaption of reduced input techniques, farmers’ behaviour and their production decisions are crucial. Based on a social-psychological approach of individual behaviour, this...

Trust and the Profitability of Rule-Breaking in Grain Production
Provedor de dados: 31
Autores: Hirschauer,   Norbert; Musshoff,   Oliver.
Malpractice in food production entails unacceptable procedures and undesirable product qualities and other negative material outcomes. Despite their physical implications, behavioural sources of risk have become known as moral hazards. The probability of malpractice increases with attached profits. It decreases with the probability of disclosure and resulting losses. It also decreases with social values, emotional bonds etc. which prevent food producers from yielding to economic temptations. Trust can be generated both by reducing the profitability of malpractice and by enhancing social trust factors. Referring to Hennessy et al. (2003), who conclude that misdirected incentives are a major source of food risk, we focus on the former and analyse the...

How Market Efficiency and the Theory of Storage Link Corn and Ethanol Markets
Provedor de dados: 31
Autores: Mallory,   Mindy L.; Hayes,   Dermot J.; Irwin,   Scott H.
In this article we use the theories of market efficiency and supply of storage to develop a conceptual link between the corn and ethanol markets and explore statistical evidence for the link. We propose that a long-run no-profit condition is established in distant futures markets for ethanol, corn, and natural gas and then use the theory of storage to define an inter-temporal equilibrium among these prices. The relationship shows that under certain conditions, future price expectations will influence current spot prices and that a short-term relationship between input and output prices will exist. This short-term relationship will contain fixed costs. We demonstrate validity of the theory using a structural price model and then by means of time-series...

An Analysis of Food Grain Consumption in Urban Jiangsu Province of China
Provedor de dados: 31
Autores: Zheng,   Zhihao; Henneberry,   Shida Rastegari.
The impacts of economic and demographic variables on the demand for food grain commodities in urban Jiangsu province of China are estimated, using both the QUAIDS and the AIDS models. Results show that the demands for wheat flour and coarse grains are price-elastic while the demands for rice and grain products are price-inelastic. Certain demographic variables show as having a significant impact on food grain demand. Finally, a decomposition of causes of changes in rice consumption over the period of 1995–2007 is performed.

Autores: Adekambi,   Souleimane Adeyemi; Diagne,   Aliou; Simtowe,   Franklin; Biaou,   Gauthier.
This study examines the relationship between agricultural technology adoption and poverty with a focus on New Rice varieties for Africa (NERICA). The NERICAs  are a group of rice varieties developed by the Africa Rice Centre during the 1990s, resulting from the inter-specific crosses between the Oryza sativa high yielding rice species from Asia and the locally adapted and multiple-stress resistant Oryza glaberrima African rice species. They are believed to provide great hope for African agriculture. Introduced in Benin in 1998, there has been no published analysis on the impact of their adoption by farmers.  The paper uses the counterfactual outcomes framework of modern evaluation theory to estimate the Local Average Treatment Effect (LATE) of NERICA...

EXPLAINING ECONOMIC INEFFICIENCY OF NEPALESE RICE FARMS: AN EMPIRICAL INVESTIGATION
Provedor de dados: 31
Autores: Dhungana,   Basanta R.; Nuthall,   Peter L.; Nartea,   Gilbert V.
Efficiency has been proven to be an important managerial tool in improving total factor productivity in agriculture. The four sources of economic inefficiency: allocative, technical, pure technical and scale inefficiency of a sample of seventy-six Nepalese rice farmers were examined using the data envelopment analysis (DEA) decomposition method. The inefficiency indices computed by the DEA were then used as the dependent variable in a Tobit (censored) regression model using decision- makers’ attributes as the explanatory variables. The results revealed relatively large inefficiencies among the farms sampled. The average economic, allocative, technical, pure technical and scale inefficiencies were 34%, 13%, 24%, 18%, and 7% respectively. There is also a...

THE VALUE OF INFORMATION IN HERBICIDE DECISION MAKING FOR WEED CONTROL IN AUSTRALIAN WHEAT CROPS
Provedor de dados: 31
Autores: Pannell,   David J.
Most weed control decisions are made with the benefit of some information about weather conditions and actual weed densities. This study is an investigation of the value of adjusting weed control decisions in response to these types of information. For a specific example, it is found that the expected value of information can reach 15% of expected gross margin. The value of information about yield prospects is higher than that for weed density. The value of information is markedly affected by the degree of risk aversion and the type of decision rule adopted. Use of information reduces the expected level of herbicide usage.

HEALTH TRADEOFFS IN PESTICIDE REGULATION
Provedor de dados: 31
Autores: Cash,   Sean B.; Sunding,   David L.; Zilberman,   David.
EPA has the authority to ban pesticides to reduce health risks to consumers from food residues. Such bans influence the price of fruits and vegetables, and the resulting consumption shifts impact consumer health. We develop a framework to compare the direct and indirect health effects of pesticide regulation, and investigate the distribution of these effects across social groups. Under some plausible scenarios, the increased incidence of disease from reduced fruit and vegetable consumption outweigh the direct benefits of regulation.  Furthermore, high income consumers receive the greatest direct health benefit from pesticide cancellations, whereas low and medium income consumers are most hurt by the resulting dietary changes.

The Production of Biofuels: Welfare and Environmental Consequences for Asia
Provedor de dados: 31
Autores: Tisdell,   Clement A.
The production of biofuels has been supported by many conservationists and environmentalists on the grounds that it reduces greenhouse gas emissions and is a renewable energy substitute for non-renewable fossil fuels, mainly oil. More recently the domestic production of biofuels (and the domestic supply of other forms of alternative energy) have been welcomed by several nations as ways to reduce their oil imports and increase their energy self-sufficiency, as for example, has happened in the United States. India also which is very dependent on oil imports has also begun to produce biofuels in Kerala and elsewhere. However, doubts have been raised about the effectiveness of biofuel use as a means to reduce the accumulation of greenhouse gases and elementary...

Trade policies form the main economic 'buffer' between one national economy and another, i.e. the general and specific elements of each nation's trade policy interact directly or indirectly with those of other nations in all economic transactions across international borders.  A nation's trade policy involves specific actions to encourage and promote or discourage foreign trade through the legal, financial and institutional environment within which foreign transactions occur.    This study evaluates the trade policy applicable to the beef and maize sub-sectors in South Africa.  Issues that are investigated include whether trade policy provides more or less protection than needed, whether it creates more openness for trade and the revealed comparative...

Optimal Herbicide Strategies Given Yield and Quality Impacts of Weeds
Provedor de dados: 31
Autores: Pannell,   David J.
Prices received by Australian wheat farmers have increasingly depended on grain quality, especially protein concentration. This concentration depends on various agronomic and physical factors including weed competition. In this paper a model of weed management in the presence of grain quality premiums is presented. Two types of quality premium are examined: a continuout linear payment schedule and a discontinuous "stepped" schedule with substantial premiums for quality levels above a critical level. The model is applied to an analysis of the impact of protein premiums on optimal management strategies for a particular weed in Western Australia. It is found that the impact of protein premiums on optimal weed management is likely to be very small indeed, even...

Wheat Marketing
Provedor de dados: 31
Autores: Ryan,   Timothy J.
Stabilization schemes for the Australian wheat industry, or marketing schemes as they are now called, first came into existence in 1914 when the Commonwealth Government exercised powers under the War Precautions Act and set up an Australian Wheat Board to acquire the crop, fix purchase prices, allocate shipping and make advance payments to growers on delivery of wheat. This first scheme was replaced by voluntary co-operatives and private trading between the two World Wars. A new Australian Wheat Board was set up again in 1939. The experience from compulsory pools during the two World Wars, incorporating the payment of fixed prices, help growers appreciate some of the advantages of centralised marketing and encouraged them to seek a compulsory national...

Prior research into variable-rate application (VRA) of fertilizer nutrients has found profitability to be lacking in single nutrient applications to U.S. cereal crops.  This study examines the yield and cost effects of VRA phosphorus, potassium and lime application on Michigan corn and soybean farm fields in 1998-2001.  After four years, we found no yield gain from site-specific management, but statistically significant added costs, resulting in no gain in profitability.  Contrary to results elsewhere, there was no evidence of enhanced spatial yield stability due to site-specific fertility management.  Likewise, there was no evidence of decreased variability of phosphorus, potassium or lime after VRA treatment.  Site-specific response functions and yield...

The development and promotion of improved crop varieties as well as efficient seed production, distribution, and marketing systems have contributed significantly to increased agricultural production and food security in Kenya. However, these impacts have not been replicated in the semi-arid midlands due to climatic, soil, and institutional factors. Following the liberalization of agriculture in the late 1980s, there has been greater participation of the private sector, non-governmental organizations, and voluntary agencies in the area. This study examined the extent to which these developments affected farmers’ access to dryland crops. The study found that the low quantity of seed traded, high cost of production, and high seed supply prices constrained the...

Autores: Ilaslan,   Gunes; White,   Gerald B.; Langhans,   Robert W.
A new CEA (Controlled Environment Agriculture) system growing Boston lettuce, Lactuca Sativa cv. ‘Vivaldi’, achieves the same quality and quantity of production every day of the year. The year-round constant quantity and quality production indicate potential for success. However, our research showed that out of nine selected U.S. locations with different climatic and economic conditions, the Northeast had 25.7 percent higher production costs for the same yield. The analysis indicated that given current prices and costs, CEA hydroponic lettuce production in northern climates such as Ithaca in upstate New York and Chicago is marginal to negative in terms of economic viability. As a result, the question arises about the future viability of CEA in areas such...

Weaning Off Corn: Crop Residues and the Transition to Cellulosic Ethanol
Provedor de dados: 31
Autores: Malcolm,   Scott A.
Recent legislation has set ambitious targets for cellulosic ethanol to be realized in the not-too-distant future. While corn-based ethanol will continue to be the most important supply, its share—but not the quantity—will diminish over time. How agriculture responds to market and environmental challenges will be in large part governed by the evolution and adoption of cellulosic ethanol production technology. One possible scenario is that development of cellulosic production technology occurs more rapidly than expected, before the establishment of alternative cellulosic feedstocks, enabling crop residues to be used in lieu of corn during the transition to dedicated energy crops. This article examines the market and environmental consequences of shifting...

A STUDY OF CEREAL PRICE INTERRELATIONSHIPS ACROSS MARKETS AND COMMODITIES AT THE WHOLESALE AND RETAIL LEVELS IN MALI
Provedor de dados: 31
Autores: Barry,   Abdoul Wahab.
Beginning in 1981, the government of Mali undertook several policy reforms to allow participation of private traders in cereal marketing, which up to that date was officially controlled by a parastatal.  These reforms can be expected to have an impact on the working of the cereals market.  One of the main objectives of this study is to assess the performance of the cereal marketing system.  The task is to study how different markets are interrelated in terms of price formation, by using wholesale and retail price data and different techniques of analysis.  These methods of analysis include bivariate correlations, calculation of margins, and multiple regression techniques.  Not only is the research aimed at showing the differences and similarities of the...

ACREAGE RESPONSES TO EXPECTED REVENUES AND PRICE RISK FOR MINOR OILSEEDS AND PROGRAM CROPS IN THE NORTHERN PLAINS
Provedor de dados: 31
Autores: Krause,   Mark A.; Koo,   Won W.
Wheat, barely, flaxseed, and oilseed sunflower acreage respond to different economic variables. Wheat and barely acreage must be divided among program-complying, program-planted, and nonprogram-planted acreage because these categories respond to different variables and respond to own expected-revenue and price-risk variables in opposite ways. Flaxseed, sunflower, and nonprogram-planted acreage of wheat and barley have highly significant, positive responses to their own expected revenue and negative responses to their own-price risk. Flaxseed and sunflower acreage have been more responsive to their lagged values than to expected revenues for wheat.

TECHNICAL EFFICIENCY OF RESETTLEMENT FARMERS OF ZIMBABWE
Provedor de dados: 31
Autores: Mushunje,   Abbyssinia; Belete,   Abenet; Fraser,   Gavin C.G.
This paper examines the technical efficiency of the resettlement sector of the agricultural system in Zimbabwe. The land reform programme aims to redistribute land from large-scale commercial farmers to the small-scale peasantry sector so as to reduce rural poverty. Since such an agrarian reform could result in higher output, higher labour absorption, and a more equitable distribution of income, it is important to assess the level of efficiency of the beneficiaries of this programme. The stochastic frontier function model of the Cobb-Douglas type was used to determine the technical efficiency of a group of 44 cotton farmers from Mutanda resettlement scheme of Manicaland province. Technical inefficiency effects are estimated and are assumed to be a function...

Relative Importance of Factors Affecting Customer’s Decisions to Buy Pick-Your-Own Versus Preharvested Fruit at North Carolina Farms
Provedor de dados: 31
Autores: Carpio,   Carlos E.; Wohlgenant,   Michael K.; Safley,   Charles D.
This study identifies the most important factors affecting customers’ decisions to buy pickyour- own versus prepicked strawberries and muscadine grapes at direct-market operations in North Carolina. The relative importance analysis identified the region of location of the operations and prices as the explanatory variable explaining most of the variation observed in the customer’s decision to choose the type of fruit to purchase. The estimated price elasticities indicate that sales of each type of fruit are very sensitive to prices.

Defining and Characterizing Approaches to Farm Management
Provedor de dados: 31
Autores: McBride,   William D.; Johnson,   James D.
Exploratory factor analysis was used to identify approaches to farm management based on a list of management questions posed to a sample of U.S. cash-grain farmers.  Three approaches were identified by the factor analysis:  price negotiation, long-term cost control, and input adjustment.  Estimated factor scores regressed against farm and operator characteristics indicate a profile of producers using each approach that is closely related to stage-of-life of the farm operator and farm business.  In addition to operator age and planning horizon, operator risk preference and farm organization and location were other important determinants of the approach to management.

ASYMMETRIC GRADING ERROR AND ADVERSE SELECTION: LEMONS IN THE CALIFORNIA PRUNE INDUSTRY
Provedor de dados: 31
Autores: Chalfant,   James A.; James,   Jennifer S.; Lavoie,   Nathalie; Sexton,   Richard J.
Grading systems are often introduced to address the classic adverse selection problem associated with asymmetric information about product quality. However, grades are rarely measured perfectly, and adverse selection outcomes may persist due to grading error. We study the effects of errors in grading, focusing on asymmetric grading errors- namely when low-quality product can erroneously be classified as high quality, but not vice versa. In conceptual model, we show the effects of asymmetric grading errors on returns to producers. Application to the California prune industry shows that grading errors reduce incentives to produce more valuable, larger prunes.

Economic Issues in Management of Herbicide-Resistant Weeds
Provedor de dados: 31
Autores: Schmidt,   Carmel P; Pannell,   David J.
Herbicide-resistant annual ryegrass (Lolium rigidum) is having a dramatic impact on the management and profitability of continuous cropping systems of southern Australia. In many cases ryegrass populations have exhibited cross resistance. where development of resistance through repeated use of one herbicide also bestows resistance to other groups of herbicides not previously used. Hence use of the major groups of selective herbicides as the predominant means of weed control is often ruled out. In this paper we discuss the development of herbicide resistance in Lolium rigidum, its costs and implications for farm management. Where high levels of resistance have developed, weed control strategies that include a range of control methods (such as increased crop...

THE IMPACT OF IMPROVED MAIZE GERMPLASM ON POVERTY ALLEVIATION: THE CASE OF TUXPENO-DERIVED MATERIAL IN MEXICO
Provedor de dados: 31
Autores: Bellon,   Mauricio R.; Adato,   Michelle; Becerril,   Javier; Mindek,   Dubravka.
This study documents how poor small-scale farmers in lowland tropical Mexico use improved maize germplasm and how this contributes to their well-being. It does this by assessing both the direct adoption of improved varieties and examining the process of their “creolization.” By exposing improved varieties for replanting, and in some cases promoting their hybridization with landraces, either by design or by accident, farmers produce what they recognize as “creolized” varieties. Our key hypothesis is that poor farmers benefit from improved germplasm through creolization. Creolization provides farmers with new options, as they deliberately modify an improved technology generated by the formal research system to suit their own circumstances and needs....

Economic Issues in Farm-to-Port Grain Storage, Handling and Transport
Provedor de dados: 31
Autores: Brennan,   Donna C.
In this paper, the literature on the economics of grain distribution systems is reviewed. The emphasis of this review is on farm to port issues and largely excludes port and shipping issues. In the first part of the paper, the discussion centres on the historical institutional environment in Australia, which was heavily regulated. The second part of the paper highlights some of the issues relating to the pricing of central grain distribution services that continue to exist even in the more competitive environment which has emerged in the 1990's. The scope for future agricultural economics research in this area is discussed.

Market and Welfare Effects of Trade Disruptions from Unapproved Biotech Crops
Provedor de dados: 31
Autores: Magnier,   Alexandre; Konduru,   Srinivasa; Kalaitzandonakes,   Nicholas G.
Genetically modified (GM) crops have been largely adopted in major exporting countries thereby representing a dominant share of a few key agricultural commodities that are traded in international markets. Regulatory reviews and approvals for the cultivation and marketing of GM crops, however, are country-specific and significant discrepancies in the amount of time required to review and approve new GM crops between importing and exporting countries has led to “asynchronous approvals”. Trade disruptions created by asynchronous approvals of GM crops are expected and can quickly deteriorate into effective trade bans because perfect segregation between approved and unapproved GM crops is difficult. The issues we examine in this paper are the potential market...

Indian Wheat and Rice Sector Policies and the Implications of Reform
Provedor de dados: 31
Autores: Landes,   Maurice R.; Jha,   Shikha; Srinivasan,   P.V.
During 1998-2002, India experienced record public surpluses of wheat and rice, sharply higher government grain subsidy outlays, and declining per capita consumption of wheat and rice. By 2006, despite continued high subsidies and sluggish domestic consumption, India developed a large wheat deficit because of reduced price incentives, weak yield growth, and rising subsidized consumption. The pronounced market cycles and declining per capita consumption for India’s major food staples are creating pressure for Indian policymakers to adjust longstanding policies. While there has been no political consensus on more fundamental reform, recent policy changes have moved toward better targeting of food subsidies to low-income consumers, decentralization of...

Learning About a New Technology: Pineapple In Ghana
Provedor de dados: 31
Autores: Conley,   Timothy G.; Udry,   Christopher R.
This paper investigates the role of social learning in the diffusion of a new agricultural technology in a developing country: Ghana. We use unique data on farmers’ communication patterns to define each individual’s information neighborhood, the set of others from whom he might learn. Our empirical strategy is to test whether farmers change their input decisions to align with those of their neighbors who were successful in previous periods. We present evidence that farmers adopt successful neighbors’ practices, conditional on many potentially confounding factors including the physical proximity of plots, credit arrangements, clan membership, and soil characteristics.

Autores: Peters,   Steven E.; Janke,   Rhonda R.; Johnson,   Dale M.; Hanson,   James C.
A long-term whole-farm analysis compared conventional and low-input farming systems.  Data from a nine-year agronomic study at the Rodale Research Farm, Kutztown, Pennsylvania, were used to analyze profitability, liquidity, solvency, and risk on a representative commercial grain farm.  Conventional and low-input farms participating in government programs are the most profitable scenarios, followed by conventional and low-input farms not participating in government programs.  All farms increased their net worth.  The low-input approach is advantageous for risk-averse farmers using a safety-first criterion.

Kazakhstan’s agricultural sector plays an important role in the country's economy. Not only does it function as an economic output producer, it also serves as a social buffer in times of transition to a market economy. The restructuring process had a strong impact on the economic performance of agricultural enterprises. As the state no longer functions as a back-up financier in times of economic downturn, farmers have to find their own sustainable instruments to manage business risks, which are significant in Kazakhstan due to the acute continental climate and the resulting revenue fluctuations.

A source-differentiated Almost Ideal Demand System model is used to analyze U.S. demand for the major tropical fresh fruit imports from different countries of origin. The tropical fresh fruits chosen for analysis include fresh bananas, fresh pineapples, papayas, and mangoes/guavas. To address endogeneity problem, we utilized an iterative 3SLS estimation method. Results show that consumer incomes are a major determinant of tropical fresh fruit import demand and most of the tropical fresh fruit imports are luxury commodities. U.S. consumers have a preference for Guatemalan and Costa Rican bananas, Costa Rican and Honduras pineapples, and Ecuador and Mexican mangoes. A competitive relationship exists between bananas from Ecuador and Colombia, Ecuador and...

Autores: Tumusiime,   Emmanuel; Brorsen,   B. Wade; Biermacher,   Jon T.; Mosali,   Jagadeesh; Johnson,   Jim; Locke,   James.
The parameters of yield response functions can vary by year. Past studies usually assume yield functions are nonstochastic or ‘limited’ stochastic. In this study, we estimate rye-ryegrass yield functions where all parameters are random. Optimal nitrogen rates are calculated for two yield response functions: linear response plateau and quadratic. Nonstochastic models are rejected in favor of stochastic parameter models. However, the economic benefits of using fully stochastic models are small since optimal nitrogen rates do not differ greatly between stochastic and nonstochastic models.

This study attempts to explain the variation in aggregate crop acreage in Argentina in the period 1960-97. It improves on previous studies by incorporating an expected yield variable and input price variables, extending the period of analysis, and attempting an aggregate crop acreage supply-response, of six crops. A single equation model is developed and the naive, moving average and simple weighted average price expectation mechanisms-are examined. Results show that a moving average specification of price expectation accounts better for the data.

Does Price or Income Affect Organic Choice? Analysis of U.S. Fresh Produce Users
Provedor de dados: 31
Autores: Smith,   Travis A.; Huang,   Chung L.; Lin,   Biing-Hwan.
This study analyzes consumer purchasing behavior of organic fresh fruits and vegetables using the 2006 Nielsen Homescan panel. An ordered logit model was estimated to quantify the impacts of economic and socio-demographic factors on the probability of a household belonging to a specific organic user group—devoted, casual, or nonuser. Results suggest that price and income, to some extent, affect consumer purchases of organic produce. Additionally, the profile of an organic produce user is most likely to consist of an Hispanic household residing in the Western United States with children under 6 years old and a household head older than 54 years with at least a college degree.

Sulphur test KCl-40 and growth of the Australian canola industry
Provedor de dados: 31
Two Australian Centre for International Agricultural Research (ACIAR) projects in the mid-1980s (Projects 8328 and 8804) funded research at the University of New England to help better understand and improve phosphorus and sulfur management in tropical agricultural systems. As tropical agriculture expands into more marginal land and production systems intensify, the demands for soil phosphorus and sulfur increase.  Major outcomes of the research were a better understanding of the nutrient dynamics in South-East Asia and the development of a new and more reliable soil test for available sulfur. The new test (KCl-40) more accurately measured the sulfur available to plants, as it was able to measure the sulfur held within organic matter. A spin-off from the...

ESTIMATING INSECTICIDE APPLICATION FREQUENCIES: A COMPARISON OF GEOMETRIC AND OTHER COUNT DATA MODELS
Provedor de dados: 31
Autores: Hubbell,   Bryan J.
The number of insecticide applications made by an apple grower to control an insect infestation is modeled as a geometric random variable.  Insecticide efficacy, rate per application, month of treatment, and method of application all have significant impacts on the expected number of applications.  The number of applications to control a given insect population is dependent on the probability of achieving successful control with a given application.  Results suggest that northeastern growers have the highest and mid-Atlantic growers the lowest probability of controlling an infestation with a given application.  Results also indicate that scales require the least and moths the most number of applications.  Growers are not responsive to per unit insecticide...

Measuring the economic value of redistributing parasitoids for the control of the maize stemborer Busseola fusca Fuller (Lepidoptera: Noctuidae) in Kenya
Provedor de dados: 31
Autores: Kipkoech,   Anderson Kipruto; Schulthess,   Fritz; Yabann,   Wilson K.; Kipsat,   Mary J.; Mithofer,   Dagmar.
This study assesses the ex ante economic impact of the establishment of two parasitoids, the scelionid egg parasitoid Telenomus isis Polaszek from West Africa and a virulent strain of the braconid larval parasitoid Cotesia sesamiae Cameron from western Kenya, to control stemborer. Using a Cobb-Douglas production function, it was estimated that yields increased by 28.5% when pesticides were used to control stemborers. The benefit-cost ratio after the establishment of the parasitoids ranged from 1:1 to 777:1, with a net present value of up to US$192 million. The study demonstrates the potential of redistributing parasitoids indigenous to Africa for the control of African stemborers. Because the benefits of biological control are positively scale dependent,...

THE ECONOMIC IMPORTANCE OF CROP ROTATION SYSTEMS: EVIDENCE FROM THE LITERATURE
Provedor de dados: 31
Autores: Gebremedhin,   Berhanu; Schwab,   Gerald.
Agricultural sustainability requires that the individual farm firm be competitive and profitable while simultaneously enhancing environmental quality and the natural resource base upon which the farm firm and agricultural economy depends.  The reliance of conventional agriculture systems on purchased inputs external to the firm presents possible challenges to the long-term sustainability of the system.  Crop rotation systems are one cropping system alternative that can reduce agriculture's dependence on external inputs through internal nutrient recycling, maintenance of the long-term productivity of the land, and breaking weed and disease cycles.  Decision criteria to choose among competing crop rotation systems can include impact on soil quality and...

Comparing Farm and Village-Level Determinant of Millet Diversity in Marginal Environments of India: The Context of Seed Systems
Provedor de dados: 31
Autores: Nagarajan,   Latha; Smale,   Melinda; Glewwe,   Paul.
The purpose of the research paper is to characterize biological diversity related to millets in the semi-arid regions of India at various spatial scales of analysis (e.g., farm household versus community levels) and place that evidence in a broader seed systems (includes both formal and informal) context. An important finding of this research is that producer access to millet genetic resources is affected by the extent to which seed is traded via formal markets or through other social institutions, along with farm and household characteristics. Findings also underscore the need for an enhanced theoretical understanding of local seed markets in analyzing crop variety choices and the diversity of materials grown in less favored environments.

Autores: Makki,   Shiva S.; Tweeten,   Luther G.; Miranda,   Mario J.
This study assesses storage and trade of wheat in an integrated global economy. Domestic and international linkages are analyzed using a dynamic rational expectations model of the world wheat market. The results of this study demonstrate the importance of endogenizing both storage and trade in studying commodity markets. Results suggest an optimal US buffer stock level of 150 million bushel. Results indicate that past government stockholdings have not followed efficient market outcomes. Private markets likely would perform better in the absence of government market distortions. Results indicate that elimination of the Export Enhancement Program by the US and of export restitution payments by the EU is unlikely to have a major impact on wheat exports from...

An econometric analysis of the competitive position of Australian cotton in the Japanese market
Provedor de dados: 31
Autores: Chang,   Hui-Shung (Christie).
Although a relatively small producer, Australia exports but about 90% of its cotton production, making it the third largest cotton exporter. This means that export performance plays a major role in determining the profitability of the Australian cotton industry. The primary aim was to determine the competitive position of Australian cotton in the Japanese market, based on the AIDS model using data from 1972 to 1998. The main findings were that the United States had a relatively strong market position and that to improve its market position, Australia should become more cost competitive and/or improve its quality image through promotion.

Policy Space for Mexican Maize: Protecting Agro-biodiversity by Promoting Rural Livelihoods
Provedor de dados: 31
Autores: Wise,   Timothy A.
Since the introduction of the North American Free Trade Agreement (NAFTA) in 1994, traditional maize farmers in Mexico have faced difficult economic conditions. In barely more than a decade, as many as one million farmers may have abandoned their land under economic pressure from rising imports, low prices for maize and other traditional crops, weak local and regional demand, and large reductions in public sector support for agriculture. The losses are environmental as well as economic. With the loss of traditional maize, there has been a documented loss of the agricultural biodiversity of which these farmers and their ancestors have been stewards for centuries. With maize trade scheduled to be fully liberalized under NAFTA in 2008, many farm groups are...

Fruit and Vegetables, and the Role They Have Played in Determining the EU’s Aggregate Measurement of Support
Provedor de dados: 31
Autores: Swinbank,   Alan.
In its periodic declarations of domestic support to the WTO, the EU has progressively reduced its amber-box declarations in line with its changing system of farm support. Surprisingly, however, in 2007/08 it managed to more than halve its amber box compared with that of the previous year, easily achieving the reduction targets being touted in the Doha Round. This was largely due to a change in the calculations for fresh fruits and vegetables. These had been linked to the entry price system, which was not affected by the 2008 fruit and vegetables reform. Why the EU chose to make this change during the ongoing Doha Round negotiations remains unclear.

The Effect of the El Nino Southern Oscillation on U.S. Corn Production and Downside Risk
Provedor de dados: 31
Autores: Tack,   Jesse B.; Ubilava,   David.
El Nino Southern Oscillation (ENSO) teleconnections imply anomalous weather conditions around the globe, causing yield shortages, price changes, and even civil unrests. Extreme ENSO events may cause catastrophic damages to crop yields, thus amplifying downside risk for producers. This study presents a framework for quantifying the effects of climate on crop yield distributions. An empirical application provides estimates of the effect that ENSO events have on the means of U.S. county-level corn yield distributions, as well as the probabilities of catastrophic crop loss. Our findings demonstrate that ENSO events strongly influence these probabilities systematically over large production regions, which has important implications for research and policy...

Optimal Management of Molds in Stored Corn
Provedor de dados: 31
Autores: Yigezu,   Yigezu A.; Alexander,   Corinne E.; Preckel,   Paul V.
Long term storage of corn is becoming more common due to the recent increase in the demand for corn by ethanol plants. Infection of maize kernels by toxigenic fungi remains a challenging storage problem despite decades of research. Experts in storage management propose the use of a combination of preventive and monitoring-based responsive strategies in response to mold risks. In this paper, a stochastic dynamic programming model is solved to determine the expected profitability and optimal combination, timing and intensity of the proposed mold management strategies using farmers’ existing infrastructure. The results show that even with relatively high monitoring costs, maintaining high quality grain using a monitoring based optimal mold management strategy...

This article is based on a socio-economic impact study of the introduction and adoption of tissue-culture (tc) technology in banana production in Kenya. It attempts to demonstrate that a prudent introduction and promotion of a new biotechnological innovation in farming can make a positive contribution to the socio-economic status of resource poor farmers in a developing country, such as Kenya. Adoption of tc technology in banana production in Kenya is considered a good example of biotechnological applications in agriculture. Hence the article hopes to make a contribution to recent debates at international levels as to whether biotechnology can make a difference in uplifting the living standards of people in the third world (Qaim, 1999; Graff, et al 2002;...

The Ricegrowers’ Cooperative Limited is a single‐desk seller of NSW Japonica rice on the export market. Confidential monthly price data supplied by the Cooperative were used to examine ‘pricing‐to‐market’ in four of its major export markets. The hypothesis of a competitive market was rejected. The Cooperative has been able to vary mark‐ups over different markets and with respect to the importer’s currency in each market. The exchange rate results in particular suggest that the Cooperative has been able to exercise market power to obtain price premiums.

Autores: Kiatpathomchai,   Sirirat; Schmitz,   P. Michael; Thongrak,   Sutonya.
The objective of this study is to assess the technical efficient frontier of rice farms using input-oriented data envelopment analysis. The frontier represents the minimum applicable level of efficiency of inputs given the current level of yields, technologies, and managerial ability among the farmers which can be used as a benchmark for efficiency improvement of rice farms. Two-stage DEA methodology of efficiency analysis was applied. The empirical results revealed that the technical efficiency of rice farming in southern Thailand could be improved through reduction of inputs by 8-14 % and the current output at 3.5 tons of paddy rice per ha could be maintained. In order to improve technical efficiency of rice farms in southern Thailand, our findings lead...

This study examines prospective additional costs associated with identity preserved (IP) transactions and their allocation among participants in the wheat marketing system (farmers, grain handlers, and millers).  Cost allocations for participants are computed across a range of potential specifications for IP transactions.  As strategies become more specific (moved toward either location, variety, or variety and location), the probability of lots meeting quality specifications for the desired end-use characteristic (absorption) generally increased and changes in costs for mills declined.  The exception is for strategies that include varieties which involve a premium paid by millers.  As strategies become more specific, higher economic costs are imposed on...

Autores: Krishna,   Vijesh V.; Qaim,   Matin.
The primary focus of the study is the changes that occurred in the pesticide-use structure of cotton production sector of India, owing to the diffusion of Bacillus thuringiensis (Bt) technology. Studies from different countries show that transgenic Bt crops can reduce chemical pesticide use with positive economic, environmental, and health effects. However, most of these studies build on cross-section survey data, so that longer term effects are uncertain. Bt resistance and secondary pest outbreaks may potentially reduce or eliminate the benefits over time, especially in developing countries where refuge strategies are often not implemented. Here, data from a unique panel survey of cotton farmers, conducted in India between 2002 and 2008, show that the Bt...

This study evaluated implications of increased bollworm problems in a 20-county area of the Texas High Plains relative to cotton yields and economic impact. Results did not indicate a serious effect of bollworms upon lint yield when insecticides were used for control. However, estimated annual reduction in farmer profit due to the bollworm for 1979-81 was over $30 million. Yields were estimated to decline about 300,000 bales without insecticide use and about 30,000 bales with insecticide use. This decline suggests potentially serious implications for the comparative economic position of cotton in this region if insecticide resistance were to develop among insect pests.

The paper provides an analysis of the impacts of the biofuel policy on the French arable crop sub-sector. The model used is a biofuel supply model composed of an agricultural module and an industrial biofuel processing module. The agricultural supply model is an aggregation of 1094 farm models, based on data from the French Farm Accountancy Data Network (FADN). Different biofuel chains are included in the model: ethanol from wheat and sugar beet, biodiesel (Vegetable Oil Methyl Ester) from rapeseed and sunflower. Scenarios are built upon the recent policy of an increased demand of biofuels for the next years, under the assumption of fulfilling the targets with domestic production only. Results show that the incorporation target of 7% of biofuels in...

Autores: Revoredo-Giha,   Cesar; Fletcher,   Stanley M.
Firm’s reputation depends on the quality of its goods and its reliability as a supplier.  This may explain observed price differences between commodities from different origins  but with the same observable characteristics. We analyse data for the Rotterdam market  and use hedonic price analysis to show the existence of a price premium that favours  the US over other origins. As secondary information points out exporter reliability as  one explanation we formalise the relationship between reliability and price premiums in  a theoretical model and analyse its implications.

A whole farm linear programming model, PRISM, was used to investigate the profitability of adopting a more intensive crop rotation in the central Mallee region of Victoria (annual rainfall 300-350mm). The model was optimised for farm profit with different amounts of working capital so that optimal proportions of a wheat-field peawheat- lupin rotation and a pasture-pasture-wheat rotation were included in the enterprise mix. Based on average yields from a 10 year rotation at the Mallee Research Station, Walpeup, increasing crop intensity from 33% of the farm to 77% of the farm increased annual profit by 38%. When the model was run again using typical input costs and average yields achieved in the region, intensification of cropping decreased annual profit by...

RICE TRADE LIBERALIZATION AND POVERTY
Provedor de dados: 31
Autores: Gulati,   Ashok; Narayanan,   Sudha.
Rice is the lifeline of almost 70% of the world's poor residing in Asia, where more than 90% of world rice production and consumption takes place. Rice trade liberalization therefore has tremendous implications for poverty. The world rice market is highly distorted, partly because of the high degree of intervention in rice markets across the world. While poor countries such as Thailand, Vietnam, and India tend to "disprotect" rice sectors, the rich countries of East Asia (Japan and Korea), Europe, and the United States heavily support their rice producers. As a result, there is great diversity in domestic rice price levels, with very high prices in the latter countries and very low prices in the former. Trade liberalization would thus result in flows from...

Evaluation of economic weights for selection and breeding in macadamia
Provedor de dados: 31
Autores: Coverdale,   Chris; Hardner,   Craig; Wegener,   Malcolm K.
The identification of economically sensitive traits is a critical step in the breeding process as it defines the direction of the breeding program. Quantifying how each trait affects the profitability of the production system further increases the efficiency of a breeding program. Production activities are ultimately aimed at maximising the level of consumer satisfaction with the product concerned which is, in turn, relfected by the profitability of the growing and processing stages of the production process. In that regard, breeding objectives need to be consistent with maximising the profitability of the farm production sector by producing genotypes with improved performance. By assigning economic weights to different traits, genotypes with differing...

Economic Analysis of Using Soybean Meal as a Mushroom Growing Substrate
Provedor de dados: 31
Autores: Fewell,   Jason E.; Gustafson,   Cole R.
Mushrooms have been grown commercially on many different substrates for years, usually agricultural by-products such as straw or stover.  Increased popularity for specialty mushrooms with consumers has led to increased production and great demand for economic substrates.  Oyster mushrooms are easier to grow relative to other types of mushrooms and their production has increased dramatically in recent years.  This study examines the economic feasibility of using soybean hulls as a primary substrate for oyster mushrooms, replacing traditional wheat straw.  The study uses a cost-benefit analysis to determine an optimal substrate based on yield and the number of crops harvested per year.   The study shows that soybean hulls, combined with corn gluten or...

• Strategic interaction between market players affects the performance of grain markets and the risk of food crises. Strategic dilemmas can arise if traders don’t trust government announcements on future maize purchases or if the government does not trust stock estimates provided by the private sector. • Government “pre-commitment” (announcing in advance how and when it will operate in the market and then behaving in a consistent manner) is found to produce superior welfare outcomes to “discretionary intervention” whereby the government operates in an unpredictable and ad hoc manner in markets. Situations of food shortage and over-supply were much more frequent under a discretionary policy environment because of the risk of poor coordination between the...

Analysis of Commodity Program Adjustments for U.S. Rice in Stochastic Framework
Provedor de dados: 31
Autores: Chavez,   Eddie C.; Wailes,   Eric J.
Potential adjustments in U.S. commodity program for rice are evaluated in this paper using stochastic analysis in a global modeling framework. Corresponding threshold and loss-compensatory increases in target price and loan rates are determined with assumed outright and gradual elimination of direct payments. Results show that if direct payments (DP) are eliminated in 2012, a 23% increase in both the target price (TP) and loan rate (LR) triggers counter-cyclical payments (CCP) 80% of the time; and it will take an increase of 48% in TP and LR to generate CCP enough to compensate for the loss in total DP. If DP is gradually removed over 5 years, the trigger and compensatory increases in TP and LR are 41% and 46%, respectively. Furthermore, if DP is...

From Kyoto to Copenhagen: Meeting the Climate Change Challenge
Provedor de dados: 31
Autores: Gaisford,   James D.
In spite of some superficial success in achieving its overall global target, there has been much disillusionment with the progress on climate change since the Kyoto Protocol was negotiated in 1997. The key problems in addressing GHG emissions under the Kyoto Protocol have been the incomplete coverage across countries and lack of credibility. While significantly more onerous reduction commitments should be expected and required of developed countries in the name of economic fairness, GHG emissions must also be capped effectively in developing countries.

THE VALUE OF PLANTING FLEXIBILITY PROVISIONS IN THE 1990 FARM BILL TO THREE REPRESENTATIVE TEXAS FARMS
Provedor de dados: 31
Autores: Chien,   Ming-Che; Leatham,   David J.
The 1990 Farm Bill reduces deficiency payments but also provides more planting flexibility for program participants.  In this study, a mean-standard deviation analysis is used to analyze the impacts of planting flexibility provisions on crop selection decisions, farm returns, and farm risk.  Results show that gains from the added planting flexibility do not offset the mandatory loss in the deficiency payments for program participants.  Planting flexibility will lead to an increase in corn and wheat planted in the Northern Plains and an increase in cotton planted in the Rolling Plains and Coastal Bend, Texas.

Background Information on the Chinese Fruit Sector
Provedor de dados: 31
Autores: Thornsbury,   Suzanne; Woods,   Mollie.
The People's Republic of China was established in 1949, ushering in an era of socialism and government centralization. Beginning in 1978, China's economy gradually transitioned from centralization to the transitional and somewhat more privatized society of today. Prior to 1978, government policies aimed at controlling food supplies and prices were common. Food rationing in 1953 was aimed at guaranteeing food for urban dwellers and included price administration by the government (Dong and Fuller, 2006). Agricultural productivity and the availability of food increased dramatically when laws that decentralized agricultural production were enacted in 1981. Food rationing and market centralization were abolished later in urban areas for non-staple food items,...

U.S./CANADA GRAIN HANDLING AND TRANSPORTATION SYSTEMS
Provedor de dados: 31
Autores: Park,   Joon J.; Koo,   Won W.
The United States and Canada have developed very different grain handling and transportation systems (GHTSs) over the last several decades to compete for global and domestic markets in Canada and the United States under CUSTA. Because the grain industries in both countries face long distance hauls, GHTSs are critically important to their operations and to producer returns.  There has been considerable pressure for change in Canada's grain handling and transportation sector. Some industry trends, such as the rationalization of elevators in the Prairies and investments in new high through-put facilities, are being driven by market and competitive forces. Changes in grain handling, reciprocal access to marketing functions, and elimination of rate caps may...

SOIL CONSERVATION OR COMMODITY PROGRAMS: TRADE OFFS DURING THE TRANSITION TO DRYLAND CROP PRODUCTION
Provedor de dados: 31
Autores: Lee,   John G.; Lacewell,   Ronald D.; Richardson,   James W.
Predicted crop yields and wind erosion rates from a multi-year/multi-crop growth simulation model provided input into a multi-period recursive QP model to evaluate erosion implications during the transition to dryland crop production on the Texas Southern High Plains.  Three farm-program participation options were considered in this study.  Participation in an extension of the current farm program resulted in an increase in net returns and wind erosion rates above nonparticipation.  Imposition of a soil loss limit without consideration of a flexible base option can significantly reduce discounted present values.  Increasing risk aversion across producers affects crop mix selection which can result in lower per acre wind erosion rates for this particular...

Driven by the expanding production of biofuels, the linkage between the agricultural and energy markets is evolving, and that has changed the market for agricultural commodities dramatically. These developments in agricultural markets consequently shifted the distribution of domestic grains and feeds and the utilization of shipping modes for these agricultural products. As the leading producer of corn, soybeans, and biofuels, Iowa is at the forefront of this shift. Because of the importance of maintaining an adequate state transportation system to accommodate the evolving patterns of grain and biofuel flows, it is important to have current information about grain flows from farms and country elevators to destination markets, along with the information...

The Impact of Weather Extremes on Agricultural Production Methods: Does Drought Increase Adoption of Conservation Tillage Practices?
Provedor de dados: 31
Autores: Ding,   Ya; Schoengold,   Karina; Tadesse,   Tsegaye.
The paper combines panel data techniques with spatial analysis to measure the impact of extreme weather events on the adoption of conservation tillage. Zellner’s SUR technique is extended to spatial panel data to correct for cross-sectional heterogeneity, spatial autocorrelation, and contemporaneous correlation. Panel data allow the identification of differences in adoption rates. The adoption of no-till, other conservation tillage, and reduced-till are estimated relative to conventional tillage. Extremely dry conditions in recent years increase the adoption of other conservation tillage practices, while spring floods in the year of production reduce the use of no-till practices.

Short term effects of moderate carbon prices on land use in the New Zealand emissions trading system: LURNZ-climate land use change simulations
Provedor de dados: 31
Autores: Kerr,   Suzi; Zhang,   Wei; Power,   William.
The New Zealand Emissions Trading Scheme (NZ ETS) was introduced through the Climate Change Response Act in September 2008 and remains in force. The forestry sector has been directly affected by the NZ ETS since 1 January 2008 and stationary energy, liquid fuels and industrial emissions have been affected since 1 July 2010. When it is fully implemented in 2015 it will cover all sources and gases including agricultural emissions. Using the Land Use in Rural New Zealand model (LURNZ), we simulate rural land use changes that could be driven by the NZETS in order that we can explore their potential implications for emissions and removals (sequestration) and rural incomes and land values.

The Australian Centre for International Agricultural Research (ACIAR), through collaborative projects with the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia, and the Chinese Academy of Forestry (CAF), has been involved in tree species selection trials in southern China since 1984. The trials were aimed at identifying fast-growing species of Eucalyptus, Acacia and Casuarina. The Chinese have been planting Australian tree species for more than 100 years, but before the ACIAR project there had been little progress in determining which species and provenances would be best for the local climate and soils. This paper presents an assessment of the economic impact of research undertaken under two ACIAR-supported projects....

The Ugandan coffee industry is facing some serious challenges, including low international prices in the international coffee market, aging coffee trees and declining productivity, and, more recently, the appearance of coffee-wilt disease, which have all contributed to the decline in both the quantity and value of coffee exports. The government of Uganda, through the Uganda Coffee Development Authority (UCDA), in 1993/94 started a coffee-replanting program to both replace coffee trees that were old or affected by coffee-wilt and expand coffee production into other suitable areas in northern and eastern Uganda. This program seems to be helping to both combat the industry’s problems and reverse the declining trends. However, the UCDA announced in 2004 that...

QUANTIFYING ECONOMIC AND ENVIRONMENTAL TRADE-OFFS OF INSTREAM FLOW REQUIREMENTS: A COMPARISON BETWEEN STEWART-HAGAN AND STEWART CROP YIELD RELATIONSHIPS
Provedor de dados: 31
Autores: Grove,   Bennie; Oosthuizen,   L.K.
Chance constrained mathematical programming was used to compare the effects of two different crop yield relationships on the economic cost to irrigation farmers while maintaining an instream flow requirement. Results showed that the Stewart-Hagan programming model underestimated the economic cost and overestimated potential return flows. Water policies based on this model will lead to the implementation of socially unacceptable water allocation policies that may even apply more pressure on stream flows. Meaningful water policies could only be advanced by a thorough understanding of the economic and hydrological consequences of alternative water allocation policies through the integration of economic and hydrological models at catchment level.

Autores: Babcock,   Bruce A.; Blackmer,   Alfred M.
The producer value of reducing temporal uncertainty concerning the level of soil nitrate is estimated for corn production in Iowa. The reduction in uncertainty is obtained through use of a late-spring nitrate test. Parametric representations of conditional densities of soil nitrates are used along with an estimated production function to estimate optimal nitrogen fertilizer applications under both uncertainty and certainty for a representative risk-neutral Iowa corn farm. Results indicate that decreasing uncertainty could reduce average fertilizer applications by up to 38% and that producer returns could be increased by up to $22.08/acre.

Grower Response to Contracts and Risk in Genetically Modified (GM) Crops
Provedor de dados: 31
Autores: Wilson,   William W.; Dahl,   Bruce L.; Maxwell,   Brett J.
Contract strategies can resolve some of the challenges that exist for property rights conformance of genetically modified (GM) crops. The purpose of this research is to determine how contract terms impact adoption decisions related to GM grain production and marketing. A simulation model was developed for prospective GM introduction in hard red spring (HRS) wheat, and distributions of net returns for growers were analyzed using stochastic dominance and stochastic efficiency. Results illustrate that contracts can be designed to induce desired behavior. Technology fees, probabilities of detection, and the level of non-GM premiums were the most notable factors influencing adoption decisions. In addition, point-of-delivery pricing and premiums for non-GM...

Autores: Vincent,   David P.; Quirke,   Derek.
The ACIAR-managed project CS1/1996/013, Herbicide-resistant weeds of wheat in India and Australia: integrated management, was designed to find a long-term method of control of Phalaris minor, a problem weed of the rice–wheat cropping system of north-western India. By 1993, the weed had developed resistance to isoproturon, a herbicide which had delivered effective weed control for 15 years. The short-term solution, implemented before the ACIAR project commenced, involved identification and registration of a new set of herbicides. But these new herbicides were expensive. To ensure high adoption they needed to be combined with changes in wheat-growing techniques that would provide cost savings to help farmers pay for them. And to avoid the re-emergence of...
