Análisis de la situación actual de la producción de maíz y de la pluriactividad de los agricultores en el Valle de Puebla.
Provedor de dados: 32
Autores: Osorio García, Nemesio.
En México el maíz es el cultivo más importante debido a que es la base de la alimentación de la población y porque actualmente se le considera como materia prima para la industria. Lo anterior hace necesaria una mayor producción de este grano para garantizar la seguridad alimentaria de los mexicanos. Por lo tanto es necesario analizar la situación actual de la producción de maíz a diferentes niveles, incluyendo el regional, para hacer propuestas que nos permitan incrementar la producción de este grano básico. En el Valle de Puebla los rendimientos de maíz son bajos comparados con los resultados experimentales en este cultivo. Los objetivos de esta investigación fueron determinar cuál es la situación actual de la utilización, oferta y demanda de la...

Stormwater management has long been a critical societal and environmental challenge for communities. An increasing number of municipalities are turning to novel approaches such as green infrastructure to develop more sustainable stormwater management systems. However, there is a need to better understand the technological decision-making processes that lead to specific outcomes within urban stormwater governance systems. We used the social-ecological system (SES) framework to build a classification system for identifying significant variables that influence urban stormwater governance decisions related to green infrastructure adoption. To adapt the framework, we relied on findings from observations at national stormwater meetings in combination with a...

Intra and Inter organisational determinants of electronic-based traceability adoption: evidences from the French agri-food industry
Provedor de dados: 31
Autores: Galliano,   Danielle; Orozco,   L.
Traceability, the ability to trace the origin of products throughout the supply chain, has become an instrument to assure food quality and safety in agri-food chains. This process is organized within both institutional and market constraints, yet it integrates also a technological sphere marked by the unprecedented development of information and communication technologies. This paper analyses the factors influencing firms’ behaviour, with regards to adopting electronic-based traceability, in the French agri-food industry. These factors (microeconomic determinants) related to firms’ internal characteristics and the factors related to their environment. We use data from the ICT and Electronic Commerce survey from 2002, carried out by the French National...

Technology Adoption and Off-Farm Household Income: The Case of Herbicide-Tolerant Soybeans
Provedor de dados: 31
Autores: Fernandez-Cornejo,   Jorge; Hendricks,   Chad; Mishra,   Ashok K.
We model the interaction of off-farm work and adoption of agricultural technologies and the impact of adopting these technologies on farm household income from on farm and off-farm sources after controlling for such interaction, and estimate the model for the case of adoption of herbicide-tolerant (HT) soybeans using a nationwide survey of soybean farms for 2000.  We find that adoption of HT soybeans is positively and significantly related to off-farm household income for U.S. soybean farmers, after controlling for other factors.  In addition, while on-farm household income is not significantly related to adoption, total household income increases significantly with adoption.

Land Degradation in Ethiopia: What do Stoves Have to Do with it?
Provedor de dados: 31
Autores: Gebreegziabher,   Zenebe; van Kooten,   G. Cornelis; van Soest,   Daan P.
Land degradation is a particularly vexing problem in developing countries; as forests are depleted, crop residues and dung are used for fuel, which degrades cropland. In Ethiopia, the government encourages tree planting and adoption of energy efficient stove technologies to mitigate land degradation. We use data from 200 households in Tigrai, Ethiopia to examine the adoption of new stove technologies. Adoption is an economic decision, related to savings in time spent collecting fuel and cooking, and cattle required for everyday purposes. Results indicate adopters of efficient stoves reduce respective wood and dung use by 68 and 316 kg per month.

Socioeconomic Profiles of Early Adopters of Precision Agriculture Technologies
Provedor de dados: 31
Autores: Daberkow,   Stan G.; McBride,   William D.
Corn producers are the largest users of cropland and agrichemicals in U.S. agriculture, and represent a major market for precision agriculture technologies. Based on a USDA survey of 950 corn-producing farms, approximately 9% utilized some aspect of precision agriculture for corn production in 1996. A logit analysis indicated that farmers were more likely to adopt precision technologies if they farmed a large number of corn acres, earned a sizable farm income, and had high expected corn yields. The probability of adoption was also higher for farm operators using a computerized farm record system, who were less than 50 years of age, and who relied on crop consultants for information on precision agriculture.

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.

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...

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....

Identifying farmer attitudes towards genetically modified (GM) crops in Scotland
Provedor de dados: 31
Autores: Hall,   Clare.
Consumer attitudes towards genetically modified (GM) food are well documented but there has been much less focus on farmer attitudes to GM technology in agriculture. This paper reports findings from a study investigating farmers’ attitudes to GM crops in Scotland. Results from a Q methodology study reveal three discourses, one apparently pro-GM and demonstrating an expectation of benefits, the second representing a more uncertain position, wary of the potential risks of the technology but likely to be reluctant adopters, and the third describing a group who demonstrate a somewhat fatalistic attitude towards the issue of GM technology adoption and impact. The paper also reports findings from a postal survey conducted as part of the Q methodology study....

Investigation of size wage premium in earning’s literature neglects the important role played by technology adoption. This study models the size selection corrected earning’s function by introducing an extra dimension of selection of technology complexity, using a sample from workers in US hog farms. The estimated wage gap between large and small farms is reduced once correction in selection is controlled. Workers compensate monetary income for better work environment, better health and more job security, in which large farms and technologically advanced farms have advantages.

Establishments in metropolitan and nonmetropolitan locations are surprisingly similar in their adoption of new technologies, worker skill requirements, use of government programs and technical assistance, exports, and sources of financing, according to the results of a nationwide survey of 3,909 manufacturing businesses. The most widespread concern of both metro and nonmetro businesses appears to be with quality of labor. Survey respondents report rapidly increasing skill requirements, and many report problems finding qualified workers. Quality of local labor is the most frequently cited problem associated with nonmetro business locations. Access to credit, transportation, and telecommunications infrastructure is a problem of secondary importance for both...

AN INITIAL INVESTIGATION OF THE POTENTIAL FOR HERMETIC PURDUE IMPROVED CROP STORAGE (PICS) BAGS TO IMPROVE INCOMES FOR MAIZE PRODUCERS IN SUB-SAHARAN AFRICA
Provedor de dados: 31
Autores: Jones,   Michael; Alexander,   Corinne E.; Lowenberg-DeBoer,   James.
Pests like the larger grain borer (P. truncatus) and the maize weevil (S. zeamis) cause significant storage losses for African maize producers.  The value of storage protection to a market-oriented farmer is a function of price seasonality, value loss prevention, and their opportunity costs of capital.  Evidence suggests that hermetic technologies like Purdue Improved Crop Storage (PICS) bags can be effective against these key maize storage pests, but sustainable technology transfer requires that it be profitable for producers. This analysis references dry weight loss figures from key life science articles and builds on previous value loss research to provide a geographic model for potential storage technology adoption.  PICS bag profitability with one and...

Making the market: How U.S. Policy influences near term agriculture and biofuel industry production and profitability under technology adoption
Provedor de dados: 31
Autores: Meyer,   Seth D.; Binfield,   Julian C.R.; Westhoff,   Patrick C.
The beneficiaries of technology adoption in agriculture and biofuels markets in the United States are heavily influenced by domestic biofuel policies and market context. Biofuel mandates, one of the key pillars of domestic biofuel policies, may significantly alter the elasticity of demand for biofuels as well as the derived demand for maize used to produce a significant share of ethanol in the United States. Using a stochastic agriculture and biofuels model, we assess how the introduction of technology may affect the crops and biofuel markets under binding and non-binding biofuel mandates and discuss the implications for analysis of EU biofuel policies.

PAYOFFS TO FARM MANAGEMENT: HOW IMPORTANT IS CROP MARKETING?
Provedor de dados: 31
Autores: Nivens,   Heather D.; Kastens,   Terry L.; Dhuyvetter,   Kevin C.
In production agriculture, good management is demonstrated by profits that are persistenly greater than those of similar neighboring farms.  This research examined the effects of management practices on risk-adjusted profit per acre for Kansas farms over 1990-1999.  The management practices were price, cost, yield, planting intensity, and technology adoption (less-tillage).  Cost management, planting intensity, and technology adoption had the greatest effect on profit per acre, and cash price management was found to have the smallest impact.  If producers wish to have continuously high profits, their efforts are best spent in management practices over which they have the most control.

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.

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.

Complementarities and differences in adoption: an application of hazard models to two technologies in Madagascar
Provedor de dados: 31
Autores: Butler,   J.S.; Moser,   Christine M.
This paper explores the adoption of two agricultural technologies, how their patterns of adoption differ, and the relationship between them.  The first technology, the System of Rice Intensification, has been studied previously and high rates of disadoption were observed in some areas.  The second technology is off-season cropping, the practice of growing crops (primarily potatoes) in the rice fields during the winter season after the rice harvest.   The rates of adoption of off-season cropping were much higher than for SRI and very little disadoption was observed.  Through this study we are trying to understand the factors that might explain the differences in adoption and how the adoption of and experience with one technology affects the likelihood of...

This study is based on data collected from 141 family-type farms in the Yatenga province in Burkina Faso. A probit approach is used to analyze the effect of perception of land degradation and other factors on the adoption of zaï and stone rows. The results of the estimation show that the availability of organic matter from small ruminants is determinant for the adoption of both zaï and stone rows. Although most of farmers are aware of the causes and consequences of land degradation, this factor does not significantly impact on farmers’ decision to invest in SWC measures. Opportunities do exist for making more efficient use of local sources of nutrients, such as small ruminants’ organic matter in combination with locally accepted SWC measures. This may...

Technology Adoption Against Invasive Species
Provedor de dados: 31
Autores: Ranjan,   Ram.
This article looks at technology adoption in agriculture that is specifically targeted against invasive species.  The analysis involves predicting the long-term distribution of technology choices when technology can be adopted and is adopted based on current and expected agricultural profits influenced by pest infestation.  The theoretical analysis is based on an extension of two authors’ findings in 1993 and incorporates the possibility that psychological factors, such as complacency, have a significant impact on technology adoption and hence disease establishment.  An empirical application is performed for soybean rust.

Why Don't Lenders Finance High-Return Technological Change in Developing-Country Agriculture?
Provedor de dados: 31
Autores: Blackman,   Allen.
Most of the literature attributes credit constraints in small-farm developing-country agriculture to the variability of returns to investment in this sector. But the literature does not fully explain lenders. reluctance to finance investments in technologies that provide both higher average and less variable returns. To fill this gap, this article develops an information-theoretic credit market model with endogenous technology choice. The model demonstrates that lenders may refuse to finance any investment in a riskless high-return technology--regardless of the interest rate they are offered--when they are imperfectly informed about loan applicants, time preferences and, therefore, about their propensities to default intentionally in order to finance...

OFF-FARM INCOME, TECHNOLOGY ADOPTION, AND FARM ECONOMIC PERFORMANCE
Provedor de dados: 31
Autores: Fernandez-Cornejo,   Jorge; Mishra,   Ashok K.; Nehring,   Richard F.; Hendricks,   Chad; Southern,   Malaya; Gregory,   Alexandra.
The economic well-being of most U.S. farm households depends on income from both onfarm and off-farm activities. Consequently, for many farm households, economic decisions (including technology adoption and other production decisions) are likely to be shaped by the allocation of managerial time among such activities. While time allocation decisions are usually not measured directly, we observe the outcomes of such decisions, such as onfarm and off-farm income. This report finds that a farm operator’s off-farm employment and off-farm income vary inversely with the size of the farm. Operators of smaller farm operations improve their economic performance by compensating for the scale disadvantages of their farm business with more off-farm involvement....

Environmental and production cost impacts of no-till: Estimates from observed behaviour
Provedor de dados: 31
Autores: Laukkanen,   Marita; Nauges,   Celine.
No-till has been promoted as a cultivation method that reduces both production costs and the environmental impacts of farming relative to conventional tillage. Using farm-level data from Finland, we show that no-till has no statistically significant effect on total variable costs but that it increases the use of plant protection products and fertilizers, and decreases the use of labor. An environmental impact simulation combining the results on input use with a nutrient and herbicide runoff model predicts that no-till produces environmental benefits on highly erodible land, but may be even detrimental to the environment in average conditions.

Autores: Saint-Macary,   Camille; Keil,   Alwin; Zeller,   Manfred.
In Vietnam, a quasi-private property regime has been established in 1993, with the issuance exchangeable and mortgageable land use right certificates. Using primary qualitative and quantitative data, this paper investigates the role of the titling policy in fostering the use of soil conservation practices by upland farmers in the northern mountains region. There, population growth and growing market demands have induced farmers to intensify agricultural production onto steep slopes. While poverty has been reduced, environmental 16 problems such as soil erosion, landslides, and declining soil fertility have become severe over the past years. Our findings suggest that soil conservation technologies although relatively well known are perceived as being...

MODIFYING THE NEO-CLASSICAL APPROACH TO TECHNOLOGY ADOPTION WITH BEHAVIORAL SCIENCE MODELS
Provedor de dados: 31
Autores: Lynne,   Gary D.
The dualistic nature of humans has been recognized for centuries.  The intriguing question is the extent to which the human being with her/his display of concern for others can simultaneously act as an egoist, the latter being descriptive of the homo oeconomicus rendition of the human.  Multiple utility theory suggests a way to approach research on such issues.  A test case of water conserving technology adaptation behavior by Florida growers is examined.  Empirical evidence supports moving toward an expanded version of the mono-utility or I-utility model to include a We-utility.

Environmental Labeling and Technology Adoption in the Presence of Strategic Interactions
Provedor de dados: 31
Autores: Konishi,   Yoshifumi.
This manuscript analyzes the effect of binary ecolabeling on the strategic competition of Cournot duopolists in environmental technology and the output market. Under binary labeling, firms' abatement technologies are not directly observable by consumers but are certified if they satisfy preset ecological standards. Given this asymmetry, I set up the regulator's problem as one of choosing a technology standard, or "cutoff," in emissions per unit of output, below which all abatement efficiency levels are certified. The regulatory authority faces a trade-off in choosing the socially optimal cutoff: The regulator would like to raise the standard to reduce emissions but needs to lower it in order to induce technology adoption. There are three important...

ASSESSING THE RESPONSE OF FARM HOUSEHOLDS TO DAIRY POLICY REFORM IN ISRAEL
Provedor de dados: 31
Autores: Kimhi,   Ayal; Rubin,   Ofir D.
After nearly fifty years of stability and stagnation of dairy market regulations in Israel, a dramatic policy reform has been enacted in 1999. The reform enabled farm households, for the first time, to trade production quotas. In addition, the reform signaled to farmers that milk prices will gradually go down in real terms, and therefore only producers who expand and become more efficient will prevail. The reform allowed for generous financial support for investment in expansion, but also required the adoption of environmental regulations which could be costly to many farm families. This paper uses data from a census of small family-operated dairy enterprises that was conducted in 2001, in order to analyze the response of farm households to the reform. The...

Revisiting the Impact of Bt Corn Adoption by U.S. Farmers
Provedor de dados: 31
Autores: Fernandez-Cornejo,   Jorge; Wechsler,   Seth James.
This study examines the impact of adopting Bt corn on farm profits, yields, and insecticide use. The study employs an econometric model that corrects for self-selection and simultaneity.  The model is estimated using nationwide farm-level survey data for 2005.  Regression analysis confirms that Bt adoption is associated with increased profits, yields and seeding rates.  However, the results of this analysis suggest that Bt adoption is not significantly related to insecticide use. This result appears to be related to the fact that insect infestation levels were lower in 2005 than they were in earlier years.

Poverty status and the impact of social networks on smallholder technology adoption in rural Ethiopia
Provedor de dados: 31
Autores: Liverpool-Tasie,   Lenis Saweda O.; Winter-Nelson,   Alex.
Despite recent traces of economic growth, Ethiopia remains one of the poorest countries in the world. Though about 80% of its population is engaged in agriculture, agricultural productivity remains low and extremely vulnerable to climatic conditions.  The adoption and use of modern technologies is generally accepted as a potential vehicle out of poverty for many but  adoption rates in the country remain low with the nature of the adoption process largely unstudied (Spielman et al, 2007). This paper studies the impact of social networks in the technology adoption process in rural Ethiopia. In particular it tests for the presence of social learning effects. In addition to geographic networks, it considers the role played by other networks with more...

Information Acquisition and Adoption of Organic Farming Practices
Provedor de dados: 31
Autores: Genius,   Margarita; Pantzios,   Christos J.; Tzouvelekas,   Vangelis.
This study offers an empirical framework for analyzing farmers' joint decisions to adopt organic farming practices and to seek technical (i.e., farming) information from various sources. To that end, a trivariate ordered probit model is specified and implemented in the case of organic land conversion in Crete, Greece. Findings suggest that the decisions of information acquisition and organic land conversion are indeed correlated, and different farming information sources play a complementary role. Structural policies improving the farmer's allocative ability are found to play an important role in encouraging organic farming adoption.

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...

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.

Factors Affecting Adoption of Cow-Calf Production Practices in Oklahoma
Provedor de dados: 31
Autores: Ward,   Clement E.; Vestal,   Mallory K.; Doye,   Damona G.; Lalman,   David L.
Most technology adoption research has focused on crops. Primary data were used to determine differences in management practices among two groups of Oklahoma cow-calf producers based on herd size and cattle income dependence. Significant differences were noted between two groups of producers (smaller operations with less dependence on cattle versus larger with more dependence on cattle) in 79% of the management practices examined. Logit models determined factors influencing the probability of adopting 17 recommended practices. Important factors included the firm goal to choose practices that reduce labor, income dependence on cattle, human capital, and size of operation.

Profitability of Hermetic Purdue Improved Crop Storage (PICS) Bags for African Common Bean Producers
Provedor de dados: 31
Autores: Jones,   Michael; Alexander,   Corinne E.; Lowenberg-DeBoer,   James.
Bruchid species like Acanthoscelides obtectus (Coleoptera) and Zabrotes subfasciatus (Coleoptera) cause significant storage losses for African common bean producers.  The value of storage protection to a market-oriented farmer is a function of price seasonality, value loss prevention, and their respective opportunity costs of capital.  Evidence suggests that hermetic technologies like Purdue Improved Crop Storage (PICS) bags could be effective against key legume storage pests, but sustainable technology introduction requires that it be profitable for producers.   While PICS bag effectiveness against these specific common bean bruchid species is still under investigation, this analysis references dry weight loss figures from life science articles and builds...

On the interaction between risk-taking and risk-sharing under farm household wealth heterogeneity
Provedor de dados: 31
Autores: Delpierre,   Matthieu; Verheyden,   Bertrand; Weynants,   Stephanie.
Empirical evidence on developing countries shows on the one hand that rich farm-households are more keen to adopt new technologies and are higher risk takers than poor households. On the other hand, however, they are shown to be less vulnerable to income shocks than poor farmers. This paper provides a rationale for these observations. Risk averse agents, heterogeneously endowed with wealth, non-cooperatively decide on their level of subscription to risk-sharing and on the degree of individual production risk they take. Rich households take more risks and subscribe more to risk-sharing. Although risk-sharing allows all households to cope with idiosyncratic shocks, the risk-taking behavior of rich households increases the covariate component of poor...

Factors Influencing the Adoption of Breeding Technologies in U.S. Hog Production
Provedor de dados: 31
Autores: Gillespie,   Jeffrey M.; Davis,   Christopher G.; Rahelizatovo,   Noro C.
An important aspect of structural change in the U.S. hog industry has been the adoption of breeding technology. The adoption of each of four breeding technologies, weekly farrowing, intensive breeding, terminal crossbreeding, and artificial insemination, in U.S. hog production is analyzed using multivariate probit analysis. Results suggest that diversification, whether the producer raised breeding stock, debt and asset levels, and producer’s education influence adoption rate. Larger, more risk-averse producers were more likely to adopt technology. Producers who rated the quality of labor available as higher were more likely to adopt management-intensive technologies.

Technology Adoption and Aggregate Energy Efficiency
Provedor de dados: 31
Autores: Pizer,   William A.; Harrington,   Winston; Kopp,   Raymond J.; Morgenstern,   Richard D.; Shih,   Jhih-Shyang.
Improved technology is often cited as a means to alter the otherwise difficult trade-off between the economic burden of regulation and environmental damage. Focusing on energy-saving technologies that mitigate the threat of climate change, we find that both energy prices and financial health influence technology adoption among a sample of industrial plants in four heavily polluting sectors. Based on a model linking technology adoption to growth in aggregate efficiency, we estimate that a doubling of energy prices, after raising the growth rate to 2.1%, would require slightly more than 50 years to generate a 50% improvement in aggregate efficiency relative to the baseline forecast.

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.

Land Degradation in Ethiopia: What Do Stoves Have To Do With It?
Provedor de dados: 31
Autores: Gebreegziabher,   Zenebe; van Kooten,   G. Cornelis; van Soest,   Daan P.
In Ethiopia deforestation is a major problem and many peasants have switched from fuelwood to dung for cooking and heating purposes, thereby damaging the agricultural productivity of cropland. The Ethiopian government has embarked on a two-pronged policy in an effort to stem deforestation and the degradation of agricultural lands: (i) tree planting or afforestation; (ii) dissemination of more efficient stove technologies. The motivation in here is, therefore, to examine the potential of the strategy of disseminating improved stoves in the rehabilitation of agricultural and forests lands. For empirical analysis we used a dataset on cross-section of 200 farm households from the highlands of Tigrai, northern Ethiopia. We used a two-step procedure reminiscent...

FACTORS INFLUENCING TECHNOLOGY ADOPTION IN A LOUISIANA AQUACULTURE SYSTEM
Provedor de dados: 31
Autores: Caffey,   Rex H.; Kazmierczak,   Richard F., Jr.
A multinomial logit model was estimated and used to analyze the impact of various producer characteristics on the adoption of flow-through and recirculating technology in soft-shelled crab production.  Because of the industry's geographic isolation and high turnover rate, data was collected by personal interviews in 1991.  The results suggest that increased adoption might be fostered by targeting education programs towards full time, family operated businesses in nontraditional production regions.  However, development of effective education programs may be hindered by the lack of a significant relationship between producer adoption decisions and the information provided by university or extension personnel.

INFORMATION AND THE ADOPTION OF PRECISION FARMING TECHNOLOGIES
Provedor de dados: 31
Autores: McBride,   William D.; Daberkow,   Stan G.
Precision farming technologies have been commercially available since the early 1990s, but the pace of adoption among U.S. farmers has been modest. This study examines the relationship between the adoption of diagnostic and application techniques of precision farming and sources of information available to farmers about precision farming. The model used in the analysis accounts for sources of self-selection in the adoption process that could bias the results. Results indicate interpersonal information sources have increased adoption relative to information from the mass media, and the private sector has been the driving force behind the diffusion of precision farming. Information from crop consultants and input suppliers has had the greatest impact on the...

Organic farmers are dependent on alternative, biology-based insect control methods and are innovative in their on-farm experimentation with new strategies.  By understanding the factors that influence the insect management portfolio chosen by organic farmers, research and education programs to promote sustainable insect management practices for all farmers may be devised.  A negative binomial model of the factors influencing the number of alternative practices adopted is applied to survey data from American organic farmers.  It is found that college-educated farmers with smaller acreages, more than half their acreage in horticultural production, and extensive experience with organic production have the greatest diversity in their insect management...

Learning, Misallocation, and Technology Adoption: Evidence from New Malaria Therapy in Tanzania
Provedor de dados: 31
Autores: Adhvaryu,   Achyuta.
I show that malaria misdiagnosis, common in resource-poor settings, decreases the expected effectiveness of an important new therapy–since only a fraction of treated individuals have malaria–and reduces the rate of learning via increased noise. Using pilot program data from Tanzania, I exploit variation in the location and timing of survey enumeration to construct reference groups composed of randomly chosen, geographically and temporally proximate acutely ill individuals. I show that learning is stronger and adoption rates are higher in villages with more misdiagnosis. Subsidizing diagnostic tools or improving initial targeting of new technologies may thus accelerate uptake through learning.

Community Pressure and Clean Technology in the Informal Sector: An Econometric Analysis of the Adoption of Propane by Traditional Mexican Brickmakers
Provedor de dados: 31
Autores: Blackman,   Allen; Bannister,   Geoffrey J.
In many developing countries the informal sector, comprised of low-technology unlicensed micro-enterprises, is a major source of pollution. Environmental management in this sector is exceptionally challenging. Though clean technologies offer a means of mitigating the problem, to our knowledge there has been no rigorous empirical research on why informal (or even small-scale) firms do and do not adopt them. As a first step towards filling this gap, this paper presents the results of an econometric analysis of the diffusion of propane among informal 'traditional' brickmakers in Cd. Juárez, Mexico--a leading source of air pollution owing to their reliance on cheap, highly polluting fuels such as used tires and scrap wood. The two key policy implications of...

The Market-based Lead Phasedown

Autores: Newell,   Richard G.; Rogers,   Kristian.
The U.S. lead phasedown was effective in meeting its environmental objectives, and did so more quickly with the allowance of permit banking. The marketable lead permit system was highly costeffective, saving hundreds of millions of dollars relative to comparable policies not allowing trading or banking. Estimates suggest that transaction costs brought about only a modest reduction in program efficiency. The market-based nature of the program also provided incentives for more efficient adoption of new lead-removing technology, relative to a uniform standard. Distributionally, it is likely that the program was actually more responsive to the cost concerns of small refiners than a similar uniform standard would have been. The flexibility of the program likely...

Binary logit analysis was used to identify the factors influencing adoption of Global Positioning System (GPS) guidance systems by cotton farmers in 11 Mid-south and Southeastern states. Results indicate that adoption was more likely by those who had already adopted other precision-farming practices and had used computers for farm management. In addition, younger and more affluent farmers were more likely to adopt. Farmers with larger farms and with relatively high yields were also more likely to adopt. Education was not a significant factor in a farmer’s decision to adopt GPS guidance systems.

Factors that affect the decision to feed or sell calves at weaning are analyzed for Arkansas cow-calf operators.  A discrete choice logit model is used to analyze the adoption of value-added cattle production.  Farm size, human capital, perception of risk/returns and enterprise diversification are hypothesized to explain this decision.  Regional factors and land quality are also accounted for.  Operator perceptions towards risk, profitability and facilities were important.  Production control and attention to marketing were also significant, but farm size and scale of cattle production had a minimal impact.  Effects of human capital and off-farm labor opportunities need further investigation.

Precision agriculture and autosteer technology are, overall, profitable investments for farmers, as previous literature has established. However, what has not been investigated is whether or not farmers perceive these technologies as such. This research postulates that cotton farmers must see potential for higher profits as a result of adopting precision technologies in order to adopt it. Using the 2009 Southern Cotton Precision Farming Survey  and multinomial logit model, this research investigates farmers’ perception of precision agriculture and how those perceptions impact adoption of the autosteer GPS guidance system. Autosteer adoption was found to be significant and positively related to the perceived future importance of precision agriculture as...

THE COMPLEX DYNAMICS OF SMALLHOLDER TECHNOLOGY ADOPTION:  THE CASE OF SRI IN MADAGASCAR
Provedor de dados: 31
Autores: Moser,   Christine M.; Barrett,   Christopher B.
This paper explores the dynamics of smallholder technology adoption, with particular reference to a high-yielding, low-external input rice production method in Madagascar.  We present a simple model of technology adoption by farm households in an environment of incomplete financial and land markets.  We then use a probit model and a symmetrically trimmed least squares estimation of a dynamic Tobit model to analyze the decisions to adopt, expand and disadopt the method.  We find that seasonal liquidity constraints discourage adoption by poorer farmers.  Learning effects – both from extension agents and from other farmers– exert significant influence over adoption decisions.

Using USDA’s Agricultural Resource Management Survey data, factors leading to the adoption of technology, management practices, and production systems by U.S. beef cow-calf producers are analyzed. Binary logit regression models are used to determine impacts of vertical integration; region of the U.S.; farm size, diversification, and tenure; and demographics on adoption decisions. Significant differences were found in adoption rates by region of the U.S., degree of vertical integration, and size of operation, suggesting the presence of economies of size and vertical economies of scope. Results also indicate high degrees of complementarity among technologies, management practices, and production systems.

STOCHASTIC TECHNOLOGY, RISK PREFERENCES AND ADOPTION OF SITE-SPECIFIC TECHNOLOGIES
Provedor de dados: 31
Autores: Isik,   Murat; Khanna,   Madhu.
This paper develops a model of farmer decision-making to examine the extent to which uncertainties about the performance of site-specific technologies (SSTs) and about the weather impact the value of these technologies. The model uses the jointly estimated risk and technology parameters to examine the impacts of SSTs on returns and nitrogen pollution. The availability of uncertain soil information and production uncertainty can lead risk-averse farmers to apply more fertilizers and generate more pollution. Ignoring the impact of uncertainty and risk preferences of farmers leads to a significant overestimation of the economic and environmental benefits of SSTs and underestimation of the required subsidy for inducing adoption of SSTs.

Effectiveness of Integrated Pest Management Dissemination Techniques:  A Case Study of Potato Farmers in Carchi, Ecuador
Provedor de dados: 31
Autores: Mauceri,   Maria; Alwang,   Jeffrey Roger; Norton,   George W.; Barrera,   Victor.
Potato farmers in Ecuador rely on chemical inputs to manage pests and optimize yields.  Integrated pest management techniques lower production costs, reduce pesticide exposure, and improve long-term agricultural sustainability.  Public extension does not, however, exist in Ecuador and cost-effective means of communicating complex messages to producers are needed.  We analyze cost-effectiveness of alternative dissemination methods, including farmer field schools (FFS), field days, pamphlets, and word-of-mouth transmission.  Field days and pamphlets have strong impacts on adoption, especially considering their low costs.  FFS are effective, but expensive.  Evidence also indicates significant diffusion from FFS to non-FFS farmers, indicating high...

Economies of Feedlot Scale, Biosecurity, Investment, and Endemic Livestock Disease
Provedor de dados: 31
Autores: Hennessy,   David A.
Infectious livestock disease creates externalities for proximate animal production enterprises. The distribution of production scale within a region should influence and be influenced by these disease externalities. Taking the distribution of the unit costs of stocking an animal as primitive, we show that an increase in the variance of these unit costs reduces consumer surplus. The effect on producer surplus, total surplus, and animal concentration across feedlots depends on the demand elasticity. A subsidy to smaller herds can reduce social welfare and immiserize the farm sector by increasing the extent of disease. While Nash behavior involves excessive stocking, disease effects can be such that aggregate output declines relative to first-best. Disease...

THE DETERMINANTS OF ADOPTION OF SUSTAINABLE AGRICULTURE TECHNOLOGIES: EVIDENCE FROM THE HILLSIDES OF HONDURAS
Provedor de dados: 31
Autores: Arellanes,   Peter; Lee,   David R.
Recent years have seen a growth of interest in the adoption and diffusion of low-input sustainable agricultural technologies among smallholder agriculturalists in developing countries.  This paper examines the adoption of one such technology, labranza minima, a form of minimum tillage, among resource-poor agricultural households in villages in central Honduras.  Logistic regression is used to analyze the determinants of adoption of minimum tillage among a sample of 250 agricultural households.  The results show that plots with irrigation, plots farmed by their owners and plots with steeper slopes were more likely canididates for minimum tillage adoption.  Farmer household characteristics are not generally found to represent significant influences on...

Intrafirm Effects on Water Conservation in Agriculture
Provedor de dados: 31
Autores: Moreno,   Georgina.
Conservation technology adoption behavior is frequently analyzed at the smallest unit of production to capture important heterogeneity among adopters. Conclusions about firm-level decisions are drawn from these microunit outcomes.  However, there may be significant intrafirm interactions that create a dependence among the microunits.  This paper tests and quantifies these effects. Using a unique dataset of agricultural water use in California, this paper finds significant differences in water price elasticities of conservation technology adoption between the standard model and models that accounts for the intrafirm interactions.

This paper examines the performance of rural groups in Kenya and addresses the methodological issues and challenges faced in doing this, and presents the empirical evidence regarding various hypothesized explanatory factors for relative performance levels. Eighty-seven groups and 442 households were surveyed using several approaches. Various performance measures were tested. Both descriptive analysis and regression models were used to gain a better understanding of the group-level and household-level factors that explain performance. Collective action is desired and practiced for a large number of tasks. The findings highlight the incredible number, diversity and dynamic nature of groups in the highlands of Kenya (and we suspect this finding is not...

Probit analysis identified factors that influence the adoption of precision farming technologies by Southeastern cotton farmers. Younger, more educated farmer who operated larger farms and were optimistic about the future of precision farming were most likely to adopt site-specific information technology. The probability of adopting variable-rate input application technology was higher for younger farmers who operated larger farms, owned more of the land they farmed, were more informed about the costs and benefits of precision farming, and were optimistic about the future of precision farming. Computer use was not important, possibly because custom hiring shifts the burden of computer use to agribusiness firms.

Estimating the Implicit Value of Crop Stubble as a Barrier to Technology Adoption in Morocco
Provedor de dados: 31
Autores: Magnan,   Nicholas; Larson,   Douglas M.
For mixed cereal-livestock farmers, cereal production provides a bundle of goods. Grain is consumed by the household or sold at market, and crop residues are used as livestock feed. The straw component of crop residue can be bought and sold at market and therefore has a well-established local market price. Crop stubble, the portion of the crop residue left on the ground, is generally not traded and therefore has no market price. Some agricultural technologies require farmers to forgo using crop stubble as feed, and cultivation of high value crops entails sacrificing residue production altogether. In this paper we apply a structural econometric model to household data from Morocco to estimate the implicit value of crop stubble. We use a sample splitting...

A Dynamic Adoption Model with Bayesian Learning: Application to the U.S. Soybean Market
Provedor de dados: 31
Autores: Ma,   Xingliang; Shi,   Guanming.
Agricultural technology adoption is often a sequential process. Farmers may adopt a new technology in part of their land first and then adjust in later years based on what they learn from the earlier partial adoption. This paper presents a dynamic adoption model with Bayesian learning, in which forward-looking farmers learn from their own experience and from their neighbors about the new technology. The model is compared to that of a myopic model, in which farmers only maximize their current benefits. We apply the analysis to a sample of U.S. soybean farmers from year 2000 to 2004 to examine their adoption pattern of a newly developed genetically modified (GM) seed technology. We show that the myopic model predicts lower adoption rates in early years than...

Farm Level Impacts of Bt Corn Adoption in a Developing Country: Evidence from the Philippines
Provedor de dados: 31
Autores: Mutuc,   Maria Erlinda M.; Pan,   Suwen; Rejesus,   Roderick M.; Yorobe,   Jose M., Jr.
This article examines the ex post farm-level impacts of Bt corn adoption in the Philippines. Using an econometric approach that addresses simultaneity, selection, and censoring problems, we show that Bt corn adoption provides modest but statistically significant increases in farm-level yields and profits. Furthermore, our results suggest that farm-level yield and profit impacts of Bt corn adoption are underestimated when censoring in the pesticide application variable is not considered in the estimation procedures. Previous literature have emphasized the importance of simultaneity and selection problems but this is the first study that have raised the issue of censoring problems in estimating the farm-level effects of Bt corn adoption.

Autores: Schreinemachers,   Pepijn; Berger,   Thomas; Sirijinda,   Aer; Praneetvatakul,   Suwanna.
This paper studies the diffusion of greenhouse agriculture in a watershed in the northern uplands of Thailand by applying econometrics and agent-based modeling in combination. Adoption has been rapid by farmers in the central valley of the watershed, while farmers at higher altitudes, lacking transferable land titles that could serve as mortgage collateral, have been unable to obtain loans for greenhouse investment. The objectives of the paper are both methodological and empirical. On the methodological side, it shows that econometrically estimated models of farm household behavior are useful to design and to parameterize an agent-based model. On the empirical side, simulation results show that if mortgage collateral would not be required, then adoption in...

We analyze technology adoption decisions of manufacturers in response to energy audits provided by Department of Energy Industrial Assessment Centers. Using fixed effects logit estimation to control for unobserved plant characteristics, we find that plants respond as expected to financial costs and benefits, though there are unmeasured project-related factors that also influence investment decisions. Revealed behavior of plants suggests that most require a payback of 15 months or less as their investment threshold, corresponding to an 80% or greater hurdle rate. This is consistent with survey results for stated investment thresholds, suggesting that these programs do not lower hurdle rates, as some suggest. Plants reject about half of recommended projects;...

Effects of Bt Cotton in India During the First Five Years of Adoption
Provedor de dados: 31
Autores: Sadashivappa,   Prakash; Qaim,   Matin.
While previous research has analyzed the impacts of Bt cotton in India, most available studies are based on one or two years of data only. We analyze the technology’s performance over the first five years of adoption, using panel data with three rounds of observations. On average, Bt adopting farmers realize pesticide reductions of about 40%, and yield advantages of 30-40%. Profit gains are in a magnitude of US $60 per acre. These benefits have been sustainable over time. Farmers’ satisfaction is reflected in a high willingness to pay for Bt seeds. Nonetheless, in 2006 Indian state governments decided to establish price caps at levels much lower than what companies had charged before. This intervention has further increased farmers’ profits, but the impact...

Autores: Calatrava-Leyva,   Javier; Franco,   Juan Agustin; Gonzalez-Roa,   Maria del Carmen.
This paper presents some results from a survey carried out in 2004 among 223 olive tree farmers from mountainous areas in the Spanish Southern provinces of Granada and Jaen regarding the adoption of soil conservation and management practices. Olive tree groves in mountainous areas are subject to a high risk of soil erosion and have to incur in higher costs of soil conservation. This results in greater difficulties to comply with cross-compliance and to benefit from agri-environmental schemes. Our main objectives are to analyse the current level of adoption of soil conservation practices and to analyse which socio-economic and institutional factors determine such adoption. Three Probit models are estimated. Dependant variables are three different soil...

Autores: Fernandez-Cornejo,   Jorge; Klotz-Ingram,   Cassandra; Jans,   Sharon.
This paper estimates the on-farm impacts of adopting herbicide-tolerant soybean on herbicide use, yields, and farm profits, using an econometric model that corrects for self-selection and simultaneity and is consistent with profit maximization.  The model is estimated using nationwide farm-level survey data for 1997.  Given that the use of herbicide-tolerant soybeans involves the substitution of a particular herbicide - primarily glyphosate - for other herbicides, we explicitly consider this substitution process in the model.

Policy interventions to promote the adoption of water saving sprinkler systems: the case of lettuce on the Gnangara Mound

Autores: Brennan,   Donna C.
The potential for improving irrigation scheduling decisions and adoption of more efficient irrigation systems is explored using a bioeconomic simulation model of lettuce production on the Gnangara Mound near Perth, Western Australia. Sandy soils with poor water and nutrient holding capacity are associated with declining marginal productivity of water at high water use, which would create an incentive to reduce water use and to adopt closer sprinkler spacing if farmers had correct information about the declining marginal productivity of water. Incorrect perceptions regarding water–yield relationships lead to over use of water by up to 50 per cent and reduce profits by $475 per crop hectare (12 per cent) in the short run, and remove the incentive to adopt...

Provedor de dados: 31
Autores: Owens,   Nicole N.; Swinton,   Scott M.; van Ravenswaay,   Eileen O.
Virtually all technology adoption studies are conducted ex post, yet policy makers often need to assess the likely level of adoption before the technology is introduced.  This study uses data from a contingent valuation survey of Michigan corn growers to assess what factors would influence the adoption of two safer corn herbicides, one that is not carcinogenic and one that does not leach. Results indicate that price, risk perception, and sources of pest control information are all important.  This suggests that public policies designed to change perceptions and improve information dissemination may encourage voluntary use of more environmentally friendly technologies.

This study uses data from a 2001 survey of Great Plains farmers to explore the adoption, usage patterns, and perceived benefits of computers and the Internet. Adoption results suggest that exposure to the technology through college, outside employment, friends, and family is ultimately more influential than farmer age and farm size. Notably, about half of those who use the Internet for farm-related business report zero economic benefits from it. Whether a farmer perceives that the Internet generates economic benefits depends primarily on how long the farmer has used the Internet for farm business and for what purposes.

We develop a stochastic-dynamic model of technology adoption that imposes fewer restrictions on behavior than do previous studies of similar decision problems.  Like these previous studies, our model is forward-looking and can be used to demonstrate the additional "hurdle rate" that must be met before adoption will take place when the future state of the world is uncertain.  Unlike these previous studies, our approach does not impose the untenable assumptions that investment in a new technology is irreversible or that technologies have unlimited useful lifetimes.  Rather, we address the more reasonable situation of costly reversibility and limited lifetimes.  Our solution method utilizes Bellman's equation and standard dynamic programming techniques....

We used the 2009 Southern Cotton Precision Farming Survey data collected from farmers in twelve U.S. states (Alabama, Arkansas, Florida, Georgia, Louisiana, Missouri, Mississippi, North Carolina, South Carolina, Tennessee, Texas, and Virginia) to understand why farmers do not adopt seemingly profitable precision farming technology. Farmers provided cost, time constraint, satisfaction with the current practice and other as reasons for not adopting precision farming technology. Results from a multinomial logit regression model indicated that manure application on field, more formal education, larger farm size, participation in conservation easement or agricultural easement generally decreases the probability of nonadoption of precision agriculture in cotton...

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. Farmer-based organizations may link farmers to these markets by helping them overcome information deficiencies with respect to production standards and consumer preferences. Based on original survey data from 241 small-scale farm households in Honduras, we find that both participation in organic markets and farmer-based groups have...

Autores: Breustedt,   Gunnar; Muller-Scheessel,   Jorg; Latacz-Lohmann,   Uwe.
This paper explores farmers’ willingness to adopt genetically modified oilseed rape prior to its commercial release and estimates the ‘demand’ for the new technology. The analysis is based upon choice experiments with 202 German arable farmers. A multinomial probit estimation revealed that GM attributes such as gross margin, expected liability from cross pollination, or flexibility in returning to conventional oilseed rape significantly affect the likelihood of adoption. Neighbouring farmers’ attitudes towards GM cropping and a number of farmer and farm characteristics were also found to be significant determinants of prospective adoption. Demand simulations suggest that adoption rates are very sensitive to the profit difference between GM and non-GM rape...

A vast literature has accumulated since crop varieties with transgenic resistance to insects and herbicide tolerance were released to farmers in 1996 and 1997. A comparatively minor segment of this literature consists of studies conducted by agricultural economists to measure the farm-level impact of transgenic crop varieties, the size and distribution of the economic benefits from adopting them, consumer attitudes toward GE products, and implications for international trade. This paper focuses only on the applied economics literature about the impact of transgenic crop varieties in non-industrialized agricultural systems, with an emphasis on methods.

An Operational Approach for Evaluating Investment Risk: An Application to the No-Till Transition
Provedor de dados: 31
Autores: Upadhyay,   Bharat Mani; Young,   Douglas L.
Roy's safety-first rule is used to provide measures popular with farmers of short and long term business risk associated with various no-till transition strategies over an investment horizon. The short run rule provided more sensitivity to inter-year financial risk than other commonly used criteria. Results revealed that speed of adoption influenced the probability of successful transition more than did the sequence of drill acquisition methods. Higher equity and larger farms had a greater chance of transition success. Slow acreage expansion with a custom or rental drill reduces risk until a no-till yield penalty is eliminated.

POISSON COUNT MODELS TO EXPLAIN THE ADOPTION OF AGRICULTURAL AND NATURAL RESOURCE MANAGEMENT TECHNOLOGIES BY SMALL FARMERS IN CENTRAL AMERICAN COUNTRIES
Provedor de dados: 31
Autores: Ramirez,   Octavio A.; Schultz,   Steven D.
Evaluations of the factors influencing the adoption of agricultural and natural resource management technologies among small farmers in developing countries have been mostly limited to qualitative discussions or simple descriptive statistics resulting in superficial and inconclusive findings. This study introduces the use of Poisson Count Regressions as a statistically appropriate procedure to analyze certain common types of adoption data. It uses them to assess the impact of key socio-economic, bio-physical, and institutional factors on the adoption of integrated pest management, agroforestry, and soil conservation technologies among small farmers in three Central American countries: Costa Rica, Panama, and El Salvador.

Adoption of Conservation-Tillage Methods and Genetically Modified Cotton
Provedor de dados: 31
Autores: Roberts,   Roland K.; English,   Burton C.; Gao,   Qi; Larson,   James A.
Adoption of herbicide-tolerant cotton and conservation tillage may be simultaneously related.  Bayes' theorem and a two-equation logit model were used to test the simultaneity hypothesis.  Evidence for Tennessee suggests that adoption of these technologies reduced residual herbicide use and soil erosion more than if adoption of these technologies were independent.

Provedor de dados: 31
Autores: Gabrielyan,   Gnel; Chintawar,   Sachin; Westra,   John V.
With increasing environmental concerns, increasing population, changing tastes and preferences of consumers towards healthier foods, and with more food safety requirements, agronomic practices have changed gradually to provide not only food and fiber but also public goods and other beneficial services from agriculture. Cover cropping is one type of technology increasingly being adopted by producers of multifunctional agriculture. Cover crops provide a range of benefits, both private and public. In this paper we identify factors affecting farmers’ choice to adopt cover crops. We examine the impact on nitrogen use from adopting cover crops and the resultant decrease in input costs. Using a two-stage approach that incorporates endogeneity of adoption in...

Agricultural Technology Adoption and Rural Poverty: Application of an Endogenous Switching Regression for Selected East African Countries
Provedor de dados: 31
Autores: Asfaw,   Solomon; Shiferaw,   Bekele A.
Achieving agricultural growth and development and thereby improving rural household welfare will require increased efforts to provide yield enhancing and natural resources conserving technologies. Agricultural research and technological improvements are therefore crucial to increase agricultural productivity and thereby reduce poverty. However evaluation of the impact of these technologies on rural household welfare have been very limited by lack of appropriate methods and most of previous research has therefore failed to move beyond estimating economic surplus and return to research investment. This paper evaluates the potential impact of adoption of modern agricultural technologies on rural household welfare measured by crop income and consumption...

Revitalizing and Modernizing Smallholder Agriculture for Food Security, Rural Development and Demobilization in a Post-War Country: The Case of the Aldeia Nova Project in Angola
Provedor de dados: 31
Autores: Kimhi,   Ayal.
The Aldeia Nova project aimed at demobilizing ex-combatants to remote areas and settling them in modern agricultural communities. Three years since the first settlers arrived at the Waku-Kungu valley, 600 families are using modern agricultural technology to produce milk, eggs and vegetables which are marketed in the urban centers of Angola. These families earn a decent living and provide employment to hundreds of others. The entire area was revitalized with thousands of families pouring in to enjoy the benefits of the booming local economy. This paper presents the concept of the Aldeia Nova project, describes its evolution, and discusses its strengths and weaknesses. It concludes that the benefits of the project go far beyond its measureable economic...

Learning-by-Doing and the Choice of Technology: The Role of Patience
Provedor de dados: 31
Autores: Karp,   Larry S.; Lee,   In Ho.
If agents learn-by-doing and are myopic, less advanced firms might adopt new technologies while more advanced firms stick with the old technology. This kind of overtaking can also occur if agents are forward looking and have high discount rates. However, overtaking never occurs if agents are sufficiently patient. A finite discount rate increases the set of states at which agents adopt new technologies, so more patient agents tend to upgrade their technology more frequently.

Simultaneous Adoption of Herbicide-Resistance and Conservation-Tillage Cotton Technologies
Provedor de dados: 31
Autores: Roberts,   Roland K.; English,   Burton C.; Gao,   Qi; Larson,   James A.
If adoption of herbicide-resistant seed and adoption of conservation-tillage practices are determined simultaneously, adoption of herbicide-resistance seed could indirectly reduce soil erosion and adoption of conservation-tillage practices could indirectly reduce residual herbicide use and increase farm profits. Our objective was to evaluate the relationship between these two technologies for Tennessee cotton production. Evidence from Bayes' theorem and a two-equation logit model suggested a simultaneous relationship. Mean elasticities for acres in herbicide-resistance seed with respect to the probability of adopting conservation-tillage practices and acres in conservation-tillage practices with respect to the probability of adopting herbicide-resistance...

Governing the Co-existence of GM Crops: Ex-Ante Regulation and Ex-Post Liability under Uncertainty and Irreversibility
Provedor de dados: 31
Autores: Beckmann,   Volker; Soregaroli,   Claudio; Wesseler,   Justus.
The future institutional environment for the co-existence of genetically modified (GM) crops, conventional crops and organic crops in Europe combines measures of ex-ante regulation and ex-post liability rules. Against this background we ask the following two questions: How does ex-ante regulation and ex-post liability under irreversibility and uncertainty affect the adoption of GM crops? What are the implications for regional agglomeration of GM and non-GM crops? Ex-ante regulations and ex-post liabilities for using GM crops will induce additional costs. These costs are modelled in a classical way. The model is advanced by including irreversibility and uncertainty and taking into account transaction costs of negotiating possible solutions with neighbouring...

After the Bubble: The Survival and Ownership of Internet Marketplaces for Farmers and Agribusiness
Provedor de dados: 31
Autores: Wheatley,   W. Parker; Buhr,   Brian L.
This paper presents a theory of how industry structure and beliefs about Internet marketplace use have driven choice and ownership of marketplaces. The theory's predictions suggest that surviving Internet marketplaces will be those with strong historical linkages in an industry and those owned by or affiliated with major commodity buyers. Comparisons of these predictions with actual outcomes provide validation of the theory. Where predictions differ from results, observations are made as to the nature of the deviations.

Autores: Banerjee,   Swagata (Ban); Martin,   Steven W.
Agricultural Resource Management Survey (ARMS) data for 2003 were used to estimate two binary logit models for two definitions of genetically modified (GM) cottonseed adoption. Results indicate conservation tillage did not positively affect adoption of GM cotton with either of these definitions, while adoption of GM cotton in the previous year did. Refuge cotton also did not affect these adoption decisions for the study year.

CONSERVATION TILLAGE AND PESTICIDE USE IN THE CORNBELT
Provedor de dados: 31
Autores: Fuglie,   Keith O.
Adoption of conservation tillage can lead to substantial environmental benefits from reduced soil erosion.  But benefits may be partially offset if adoption increases reliance on agricultural chemicals.  Using area study data from the Cornbelt, this study examines factors affecting adoption of no-till and other conservation tillage systems and their effect on chemical use and corn yield.  The results find no evidence that herbicide or fertilizer application rates are higher on fields with conservation tillage systems compared with conventional tillage.  However, insecticide use may increase somewhat and yield may be lower.  Current demographic trends in U.S. agriculture favor continued diffusion of conservation tillage.

Provedor de dados: 106
Autores: Sopheap, U.; Aran Patanothai; Aye,T.M.
Cassava is one of the most important upland crops of Cambodia. While improved technologies are needed for sustainable production of the crop, their adoption depends on how farmers view cassava against other crops. The objective of this study was to assess the perception of Cambodian farmers on growing cassava, relative to other upland crops. The study was conducted in Kampong Cham province in Northeast Cambodia which has the largest cassava production area in the country. Secondary data on production and price of cassava and other crops were collected, and 45 households in four cassava production zones were interviewed to obtain information on farmer’s perceptions on cassava and other crops. The results showed that production of cassava and other upland...

Estimation of the lifespan of agricultural tractor using a diffusion model at the aggregate level
Provedor de dados: 118
Autores: Muñoz,Ricardo; Llanos,José.
The adoption of agricultural tractors by farms has resulted in different combinations, relationships and established ways of production of localities, regions and countries. The dynamics of the tractorization process are defined by the balance of the units that enter the fleet and those that are removed at the end of their useful life. This study uses a diffusion pattern and aggregated adoption of the agricultural tractor, the parameters of which were determined using a nonlinear estimation procedure and country-level data for Chile. Using the predictive power of the model, a longitudinal series of tractor fleets was estimated, and then the balance was calculated considering the units that were discharged. To more accurately determine the average lifespan...

Adoption of beef cattle traceability at farm level in São Paulo State, Brazil
Provedor de dados: 65
Autores: Vinholis,Marcela de Mello Brandão; Carrer,Marcelo José; Souza Filho,Hildo Meirelles de.
ABSTRACT: This paper aimed to identify the determinants of beef traceability adoption at farm level in São Paulo State, Brazil. A sample survey of 32 farmers who adopted the European Union certified traceability and 52 other farmers who did not adopt traceability provided data to test hypotheses on determinant factors. Three binomial logit models were used in the analysis. Results suggested that capital-intensive livestock production system, high scale production, access to specialized information and high level of human and social capital play significant role in the adoption decision.
