Adoption of an orphan infant in wild black and gold howler monkeys (Alouatta caraya)
Provedor de dados: 81
Autores: Pavé,Romina; Kowalewski,Martín M.; Zunino,Gabriel E.
This study reports the first case of adoption in a wild group of black and gold howler monkeys (Alouatta caraya). After the death of one adult female with a dependent infant, her daughter with a dependent infant adopted the orphan of similar age of her own infant. We recorded the activity and proximity between the adopter and both infants during two following days. The adoptive female appeared to provide equal treatment toward both infants and the orphan seemed to recognize the female as his mother. This report suggests that adult females of A. caraya can rear two infants at once.

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: Makokha,   Stella Nabwile; Karugia,   Joseph Thuo; Staal,   Steven J.; Oluoch-Kosura,   Willis.
Indicators of poverty in western Kenya show high poverty levels. The area has low dairy development yet the potential for dairy development is quite high. Dairy farming has the potential to reduce poverty by increasing incomes and reducing unemployment. This paper reports factor interrelationships in dairy adoption with a view to understanding factors that influence adoption. The binary probit model was used to analyse data from 1575 households. Contrary to findings from similar studies elsewhere, some factors had a negative association with adoption, thus unfolding a unique adoption process. The association between the factor interactive affects and technology adoption highlighted the importance of exploring factor interrelationships. The widely held...

AN ECONOMIC ASSESSMENT OF THE WHOLE-FARM IMPACT OF PRECISION AGRICULTURE
Provedor de dados: 31
Autores: Olson,   Kent D.; Elisabeth,   Pascal.
The full impact of an investment in a management information system (MIS), such as precision agriculture (PA), comes from improved managerial decision making throughout the whole farm and not just from improvements in a specific part of the farm.  This study was conducted to determine whether the adoption of PA had a positive impact on whole-farm profitability. To overcome problems of simultaneity and self-selection in the adoption decision of PA, this study used a two stage econometric model using data from farms in Southwest Minnesota. The PA adoption decision was evaluated in the first stage, and the impact of adopting PA was evaluated in the second stage. The whole farm rate of return to assets (ROA) was used to measure the impact of PA. For all 212...

A GROUP INCENTIVE PROGRAM FOR FARMER ADOPTION OF BEST MANAGEMENT PRACTICES: AN APPLICATION TO THE NITRATE POLLUTION PROBLEM IN CENTRAL ILLINOIS
Provedor de dados: 31
Autores: Ipe,   Viju C.; DeVuyst,   Eric A.
The paper demonstrates a group incentive program to encourage farmer adoption of best management practices.  It is demonstrated that the best management practices may not actually reduce farm profits but may increase farm profits and reduce environmental pollution.  This may bring about a win-win situation for sponsor, the farmer participating in the program, and  the society as a whole.  The results show that the farmers subjective beliefs about response of corn yields and profits to nitrogen application differ from the simulated responses which in turn results in the willingness-to-Accept for adoption best management practices significantly higher than the expected program payments.    The program could be implemented as an educational effort to...

Adoption of Conservation Agriculture Technologies by Smallholder Farmers in the Shamva District of Zimbabwe: A Tobit application
Provedor de dados: 31
Autores: Chiputwa,   Brian; Langyintuo,   Augustine S.; Wall,   Patrick.
Conventional agricultural practices such as the use of the moldboard plough are no longer sustainable due to their extensive soil degradation effects. As a panacea, several Conservation Agriculture (CA) technologies have been promoted to improve soil structure and water conservation. However, adoption of these technologies has been resisted by smallholder farmers and identifying causes of the low adoption rates to facilitate intervention strategies remains a challenge to development practitioners. Using data from 100 farmers, this paper uses a Tobit application to assess the underlying factors important in determining farmers’ adoption of zero-tillage, crop rotation and contour ridging technologies. Empirical results suggest that adoption and use intensity...

Autores: Bett,   Charles.
In this paper the conceptual framework of individual farmers' adoption decisions of new agricultural technologies is used to identify factors that influence adoption modified fanya juu terraces in semi-arid eastern Kenya. The adoption decision model was specified using farm and farmers' characteristics and technology characteristics though likely to influence farmers' adoption behaviour. To test intensity of adoption a Torbit model was specified and estimated. Results of logit regression analysis reveal that access to markets, education, costs, technology attributes, labour, credit and risk preferences significantly influenced adoption decisions. Results from the estimated intensity of adoption model (tobit) show that variation in the proportion of land...

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...

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.

Agricultural biotechnology has been advancing very rapidly, and while it presents many promises, it also poses as many questions. Many dimensions to agricultural biotechnology need to be considered to adequately inform public policy. Policy is made more difficult by the fact that agricultural biotechnology encompasses many policy issues addressed in very different ways. We have identified several key areas — agricultural research policy, industry structure, production and marketing, consumer issues, and future world food demand — where agricultural biotechnology is dramatically affecting the public policy agenda. This report focuses on the economic aspects of these issues and addresses some current and timely issues as well as longer term issues.

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.

The traditional way of information dissemination has been through people; the modern way is through the electronic media – improved information and communication technologies (ICTs).  For effectiveness, modern ICTs should help women to improve on their income generating capacity.  Issues of level of resource capacity of women, information needed, and current sources of such information become important.  This study sought to investigate the issues above with respect to rural women food producers in the Mfantsiman District of Ghana.  Simple descriptive statistics and econometric models were employed in the data analysis of 91 randomly selected respondents.  The results of the study showed that: In general, the women food producers were aged, subsistence...

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...

Food-safety Standards and Farmers Health: Evidence from Kenyan’s Export Vegetable Growers
Provedor de dados: 31
Autores: Asfaw,   Solomon; Mithofer,   Dagmar; Waibel,   Hermann.
Limited empirical evidence exists either to confirm or refute the hypotheses that food-safety standards confer a positive external effect on farmers adopting it. This article makes use of health indicators obtained from a random cross-section sample of 439 small-scale export farmers in Kenya to evaluate the impact of EU retailer food-safety standards on producers’ health. Results show average cost of pesticide-related health risks at about 165 KSh and 324 KSh per cropping season for GlobalGAP adopters and non-adopters export producers, respectively. These costs equal 86.4% of the mean household chemical expenditure per cropping season for non-adopters and 39.6% of those adopters. Using instrumental variable econometric techniques we demonstrate that...

Technology Adoption And Pest Control Strategies Among  UK Cereal Farmers: Evidence from Parametric and  Nonparametric Count Data Models
Provedor de dados: 31
Autores: Sharma,   Abhijit; Bailey,   Alastair; Fraser,   Iain.
This paper examines technology adoption and integrated pest management strategies employed by UK farmers, using both parametric and nonparametric methods.  We employ a unique survey data set collected from UK cereal farmers to assess  the determinants of technology adoption in relation to pest management. Our preferred model specification is nonparametric which makes use of the recently developed methods of Li and Racine (2007) and Racine and Li (2004). These methods allow us to combine categorical and continuous data and thereby avoid sample splitting and resulting efficiency losses. Our analysis reveals that total area farmed is positively related to the number of technologies adopted, whereas age is negatively  related. We also find evidence of...

Adoption and Abandonment of Organic Farming: An Empirical Investigation of the Irish Drystock Sector
Provedor de dados: 31
Autores: Lapple,   Doris; Donnellan,   Trevor.
The adoption and possible abandonment of organic farming has yet received little attention in the literature. As time plays an important role in explaining farming decisions, a dynamic econometric framework, namely duration analysis, is used. The probability of entry to and exit of the organic drystock sector is modeled considering a wide range of economic and non‐economic factors. Organic support payments emerge as important driving factor of adoption over time. The empirical results also highlight the importance of environmental and risk attitudes, farming experience as well as influence of other organic farmers on the probability to adopt organic farming; whereas decisions to abandon organic farming appear to be mainly driven by economic and structural...

Autores: Hoag,   Dana L.; Ascough,   James C.; Frasier,   W. Marshall.
Computers change rapidly, yet the last survey on computer use in agriculture was in 1991.  We surveyed Great Plains producers in 1995 and used logit analysis to characterize adopters and non-adopters.  About 37% of these producers use computers which is consistent with the general population.  We confirmed previous surveys emphasizing the importance of education, age/experience, and other farm characteristics on adoption.  However, we also found that education and experience may no longer be a significant influence.  Future research and education could focus on when and where computers are most needed, and therefore when adoption is most appropriate.

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...

Autores: Simtowe,   Franklin; Zeller,   Manfred; Diagne,   Aliou.
The paper investigates the impact of credit constraints on the adoption of hybrid maize among rural households in Malawi using the treatment-effects model. Results reveal that after effectively correcting for endogeneity, credit constraints have a reducing effect on the size of land allocated to hybrid maize. Farmers with larger land holdings allocate more land to hybrid maize while older farmers allocate less land to hybrid maize. These findings suggest that there is scope for increasing the cultivation of hybrid maize in Malawi if credit is targeted at younger farmers that are credit-constrained.

Autores: Gedikoglu,   Haluk; McCann,   Laura M.J.; Artz,   Georgeanne M.
Off-farm income as a share of total farm household income has been increasing. Previous studies found inconsistent results regarding the impact of off-farm income on adoption of conservation practices. We test the hypothesis that off-farm employment has a positive impact on adoption of capital incentive practices and a negative impact on adoption of labor-intensive practices. The results confirm that adoption of injecting manure into the soil, a capital intensive practice, is positively and significantly impacted by off-farm employment of the operator. However, off-farm employment variables had no effect on adoption of record keeping.

Autores: Herzfeld,   Thomas; Drescher,   Larissa S.; Grebitus,   Carola.
Privately initiated food quality standards are currently important elements in the marketing of food and agricultural products. At the same time, they stand in the centre of a discussion about potential negative effects on small farmers and farmers in developing countries. This study aims at analysing the adoption of two private food standards, BRC Technical Food Standard and GlobalGAP, at an aggregated cross-country level. The results of the econometric analysis reveal some (potential) barriers for developing countries to access this type of organisational innovation. Certificates seem to be issued more probably in larger and wealthier countries, countries with a better institutional quality, better infrastructural conditions and in former UK colonies.

Adoption of Phytase by Livestock Farmers
Provedor de dados: 31
Autores: Stahlman,   Michael; McCann,   Laura M.J.; Gedikoglu,   Haluk.
Phytase represents a potential win/win management practice for non-ruminant producers since it can reduce the need for phosphorous supplementation and also result in lower phosphorous runoff.  Cost of phytase has decreased and cost of phosphorous has increased.  The reported adoption rate for phytase for non-ruminants was 17.2 percent, however it is currently added to virtually all swine and poultry premixes by feed manufacturers due to the cost savings.  People were more likely to say they use phytase if they think it is profitable, not time intensive, and improves water quality.

Participatory technology development has been used for quite some time. However, little is known about how farmers perceive participatory methods and processes. Understanding farmers’ concerns about the participatory process can be an important starting point and can further the ultimate aim of encouraging sustained technology adoption. An ex-post participatory technology development and transfer evaluation was carried out in Zimbabwe in 2006/07 involving 231 farmers. It was revealed that use of demonstration trials encouraged the most participation and subsequent adoption and adaptation of the technologies to suit specific needs. The participatory nature of the process encouraged greater knowledge sharing among farmers and gave them more confidence in the...

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...

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 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...

Consumer Perception of Sorghum Variety Attributes in the Lake Zone Tanzania
Provedor de dados: 31
Autores: Mafuru,   January M.; Norman,   David W.; Fox,   J.S.
Many sorghum varieties have been developed by research institutes in an effort to address food security problems in the semi-arid areas of Tanzania. Although sorghum is better adapted to drier areas than maize, farmer adoption rates for sorghum varieties are always lower than that of maize. In addition, maize based food is more acceptable to urban consumers than sorghum based food. In this study consumer evaluated quality attributes of sorghum ugali based on different varieties in order to determine marketing potential relating to the different improved sorghum varieties. A total of 231 consumers, randomly selected from urban and rural areas participated in a food panel to evaluate ugali prepared from five sorghum varieties (three improved, two local)....

Adoption and impact of an award winning post-harvest technology: The ASI rice thresher in the Senegal River Valley
Provedor de dados: 31
Autores: Diagne,   Mandiaye; Demont,   Matty; Diagne,   Aliou.
In Senegal, one of the highest rice import-dependent countries in Sub-Saharian Africa, double cropping is recommended in the new national program for the Great Offensive for Food and Abundance (GOANA) to boost rice production. This target impels the respect of cropping calendar by using improved technologies like the ASI thresher-cleaner. The causal or treatment effect framework (ATE and LATE) is used to estimate the ASI adoption rate and impact. The results show that the true ASI adoption rate would be 86 % if all the population of irrigated rice farmers were exposed to it. The socioeconomic characteristics that increase the probability to adopt the ASI thresher are farmer experience, farm size, and participation to ASI field experiments and/or contact...

DEFORESTATION AND AGROFORESTRY ADOPTION IN TROPICAL FORESTS: CAN WE GENERALIZE? SOME RESULTS FROM CAMPECHE, MEXICO AND RONDONIA, BRAZIL
Provedor de dados: 31
Autores: Casey,   James F.; Caviglia-Harris,   Jill L.
The adoption of sustainable agriculture and other sustainable forestry  methods that can help to reduce tropical deforestation have received a great deal of attention in  the literature (Adesina and Zinnah 1993, Akinola and Young 1985, Feder and Slade 1984, Holden 1993, Kebede et al. 1990). Although results from different studies can be compared in an absolute sense, there are very few individual studies that compare results and determine, through empirical analysis, whether policy can be universally applied. This paper uses farm-level data to determine whether some universal conclusions can be drawn about the adoption of agroforestry by peasant farmers in developing countries by comparing the land use choices of farmers in Rondônia, Brazil and Campeche,...

INTRODUCING NEW TECHNOLOGIES AND MARKETING STRATEGIES FOR HOUSEHOLDS WITH MALNUTRITION: AN ETHIOPIAN CASE STUDY
Provedor de dados: 31
Autores: Yigezu,   Yigezu A.; Sanders,   John H.
Many developing regions have excellent potential agricultural resources. However, historically population has become so concentrated on such small holdings that acute poverty and malnutrition now predominate. The food scientists’ response to the chronic nutritional problem has often been subsidized bio-fortification with nutritional supplements or more recently cultivars with higher nutrient levels. Where much of the population is in this inadequate nutrition category as in highland Ethiopia, the supplements are neither financially feasible nor sustainable. The cultivars can provide a few critical nutrients but are not a comprehensive solution. To improve nutrition, it is necessary to increase income so that an increased quality and quantitative diet can...

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....

Autores: Nwankwo,   Uche M.; Wolfgang,   Bokelmann.
This paper is aimed at relating income fluctuation with adoptable innovations, adopter category and their access to some variables than those explained in the neoclassical economics principle of labor market demand and supply equilibrium. Using a quantitative and qualitative case study of some farmers in two States, we considered whether respondents are earning enough income and what constraints they face. The von Hipple’s lead user concept and decision model of risk aversion under uncertainty were used to explain causes of variability. Notably, farmers with enough steady income have access to market, various information and are less risk averse.

Autores: Kisaka-Lwayo,   Maggie.
Discriminant analysis was used to identify the characteristics that distinguish between fully-certified organic, partially-certified organic and non-organic farmers in Umbumbulu district, KwaZulu-Natal (KZN), South Africa (SA) during October- November 2004. 200 farmers interviewed were drawn by purposively selecting the 151 members of the Ezemvelo Farmers’ Organisation (EFO), and by random sampling 49 non-organic farmers in wards neighbouring EFO. Results from the two estimated discriminant functions suggested that farmers with higher household sizes, incomes, input costs per hectare and number of chickens owned, locations further from innovators and less risk aversion were more likely to be certified as organic. Household location should be considered in...

This study analyzes the factors driving interest in two agroforestry practices, riparian buffers and forest farming. Because agroforestry is outside main stream commodity production in US agriculture, the purpose is to evaluate a framework to understand attitudes. The framework incorporates Pierre Bourdieu's notions of "habitus" and "field" along with individual economic and demographic characteristics of farm operators' traditionally used in adoption studies. Four attitudes are analyzed: disengagers, conservatives, lifestyle, and accumulators.  A Logit regression measures the effects of respondents' attitudes, and other internal and external factors to assess interest in each practice. The data used is from a household survey of 364 farm-operators from...

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.

Analysis of the Adoption of Irrigation Technologies Under Uncertain Water Availability
Provedor de dados: 31
Autores: Escribano,   Maria Jesus; Calatrava-Leyva,   Javier.
This paper analyses the adoption process of water-conserving irrigation technologies by a risk averse farmer in a context of uncertain water availability. Firstly, it is analytically shown that the increase in water efficiency that the new technology allows results in a decrease in the cost of the effective irrigation water applied, as well as in an increase in both effective water applied and crop production. It is also concluded that the optimal amount of irrigation water applied depends on individual risk preferences of the producer, on the variance and asymmetry of the cost of water applied, and on the elasticity of the marginal productivity of the effective water applied. Lastly, it is theoretically shown that an increase in the level of uncertainty...

This study analyses the impact of the liberalization on the intensification of maize production in Kenya. It first analyses the impact of liberalization on input and output prices, followed by an analysis of farmer practices comparing two major farmer surveys, from 1992 and 2002. The results show that liberalization has had a general positive impact on the evolution of prices, with a decrease of input/output price ratios. However, fluctuations of maize prices has become very high and, combined with a decrease of marketing by the marketing board, has increased the uncertainty in maize production. The liberalization has also resulted in a decrease in extension services. Fortunately, farmers have an increased access to credit services. The combined effect of...

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...

Modern Supply Chains and Product Innovation: How Can Smallholder Farmers Benefit?
Provedor de dados: 31
Autores: Schipmann,   Christin; Qaim,   Matin.
There is an emerging body of literature analysing how smallholder farmers in developing countries can benefit from modern supply chains. However, most of the available studies concentrate on export markets and fail to capture spillover effects that modern supply chains may have on local markets. Here, we analyse the case of sweet pepper in Thailand, which was initially introduced as a product innovation in modern supply chains, but which is now widely traded also in more traditional markets. Using survey data from smallholder farmers and econometric techniques, we show that sweet pepper cultivation contributes significantly to higher household incomes. Strikingly, at this stage, participation in modern supply chains does not lead to higher incomes than...

Re-considering Agri-Environmental Schemes premiums: the impact of fixed costs in sign-up decisions
Provedor de dados: 31
Autores: Barreiro-Hurlé,   Jesús; Espinosa-Goded,   Maria; Dupraz,   Pierre.
Current EU legislation states that premiums for agri-environmental schemes must be calculated based on forgone profit and additional costs. This approach has been implemented for the last decades without much success in farmer uptake, a situation that might even worsen as the 20% additional payment as incentive for participation has been excluded in the new EU Rural Development Framework 2007-2013. This paper tries to explain why supply side estimated premiums might not suffice to assure farm profitability investigating the role that fixed costs have on adoption. A farm profit maximizing model is proposed where fixed and transaction costs are split from variations in marginal profit. This model is then developed to identify the potential barriers to...

We investigate whether social capital in the form of community involvement affects farmers’ choice to use sustainable agricultural practices. Using associational memberships as a measure of community involvement we study its effects on agricultural practices among Georgia farmers. Our findings show that, first, community involvement had a positive effect on the decision to adopt sustainable agricultural practices, and, secondly, it also had a positive effect on the extent to which farmers adopt these practices. These findings establish an additional dimension to the benefits that would accrue to policies that promote social interaction and civic engagement in rural areas.

Natural resource degradation and water scarcity are a global concern, which typically threatens the sustainability of smallholder farmers' livelihoods in semi-arid developing areas.  As part of research efforts, a number of water-conservation technologies (WCT) have been developed, yet with low adoption rates in smallholder farming environments.  This paper discusses the concepts of adoption and innovation, comparing the perspectives of research operators to the ones of smallholder farmers.  Discrepancies are highlighted and ultimately explain low uptake of technologies by farmer.  Then it addresses socio-economic factors affecting such adoption.

The Environmental Quality Incentive Program is designed to improve environmental stewardship of crop and livestock production.  Funds requested through the program greatly exceed the supply.  Recent changes make the program more attractive for larger farmers.  A survey of farmers in Missouri and Iowa found that larger farmers (in terms of farm sales) and those without a personal concern for water quality in their county are significantly more likely to be aware of EQIP.  Those who plan to expand in the next five years, and those who use and trust public information sources, are more likely to be aware of the program and also to participate in EQIP.

Policy-Induced Technology Adoption: Evidence from the U.S. Lead Phasedown
Provedor de dados: 31
Autores: Kerr,   Suzi; Newell,   Richard G.
The theory of environmental regulation suggests that economic instruments, such as taxes and tradable permits, create more effective technology adoption incentives than conventional regulatory standards. We explore this issue for an important industry undergoing technological responses to a dramatic decrease in allowed pollution levels - the petroleum industry's phasedown of lead in gasoline. Using a panel of refineries from 1971 to 1995, we provide some of the first direct evidence that alternative policies affect the pattern of adoption in expected ways. Importantly, we find that the tradable permit system used during the lead phasedown provided incentives for more efficient technology adoption decisions. Where environmentally appropriate, this suggests...

The Impact of Adoption of Genetically Modified Corn on the Off-Farm Labor Supply in the United States
Provedor de dados: 31
Autores: Chintawar,   Sachin; Mishra,   Ashok K.; Gillespie,   Jeffrey M.
With the production and cropping efficiency gains from adoption of Genetically Modified (GM) corn, the number of acres planted has increased steadily over the past decade. Also, the adoption of GM crops in general has an impact on the labor allocation decisions of farm operators. Using a large sample of Agricultural Resource Management Survey (ARMS) data, we estimate a two-stage left-censored simultaneous Tobit model to estimate the impact of adoption of GM corn on the off-farm labor supply of farm operators. Results indicate that the adoption of GM corn has had a negative and significant impact on the off-farm labor supply.

We examine the factors affecting the willingness of German farmers to adopt genetically modified (GM) oilseed rape after the pending commercial release of GM varieties. The analysis is based mainly on a web-based Discrete Choice Experiment with 217 oilseed rape growers in Germany. The determinants of adoption were estimated with the use of a multinomial probit model. Results indicate a significant impact of economic determinants on the adoption willingness: the difference in gross margins between GM and conventional rape, the probability and level of liability for damage caused by cross-pollination, and the length of the waiting period before a farmer can return to conventional rape are all highly significant. Among the farm characteristics, farm size...

Farmers' Willingness to Grow Cover Crops:  Examining the Economic Factors of Adoption in Alabama
Provedor de dados: 31
Autores: Bergtold,   Jason S.; Fewell,   Jason E.; Duffy,   Patricia A.
The inclusion of cover crops in cropping systems brings both direct and indirect costs and benefits. The literature has shown that cover crops can improve soil conservation and productivity, potentially improving cash crop yields and decreasing cash crop production costs. Farmers will adopt cover crops if the net economic benefit of utilizing them is positive. This study examines farmers’ willingness to grow cover crops as a soil conservation practice and to examine the socio-economic factors affecting their decision. Survey data collected in 2007-8 from Alabama farmers about cover crop adoption and management is utilized to estimate a cover crop adoption model.

Factors that affect the use of herbicides in Philippine rice farming systems
Provedor de dados: 31
Autores: Beltran,   Jesusa C.; Pannell,   David J.; Doole,   Graeme J.; White, Benedict.
This study involves the application of a random-effects double-hurdle model to survey data to identify the farm-level factors affecting the adoption and intensity of herbicide use in rice production in the Philippines. Results broadly indicate apparent differences in the degree to which important explanatory variables affect the intensity and adoption decisions. The age of the farmer, household size, and irrigation are the significant predictors influencing the decision of farmers to use herbicides, while economic variables such as the price of herbicides, total income of farmers, and the use of bank loans or credit are the highly significant factors determining the intensity of herbicide use. Significant determinants of both the adoption and intensity...

As part of a major effort to address soil fertility decline in West Africa, a project on Balanced Nutrient Management Systems (BNMS) has since 2000 been implemented in the northern Guinea savanna (NGS) of Nigeria. The project has tested and promoted two major technology packages, including a combined application of inorganic fertilizer and manure (BNMS-manure) and a soybean/maize rotation practice referred to as BNMS-rotation.  This study employed Tobit model to examine factors that influence the adoption and intensity of utilization of BNMS technologies in the NGS of Nigeria. Results showed that less than 10% of the sample households adopted at least one of the two components of the technology package by the end of 2002.  However, by 2005 the adoption of...

In order to diversify the sources of incomes of the country, to reduce the financial risks and to improve the farmers’ revenues, the government of Benin decided to promote new agricultural sectors. One of those new sub-sectors is shea tree which is targeted in this study. Due to the painful of certain stages of shea butter processing, the semi-mechanization was initiated. The paper uses data from a stratified random sample of 198 shea butter producers to assess the adoption and impact of this semi-mechanization in North-Benin. A multinomial probit model is estimated to analyze the factors which explain the adoption of each type of technology. A counterfactual approach drawing from a modern evaluation theory is used to evaluate the impact of this...

Development and Dissemination of Improved Cassava Varieties in Uganda: Analysis of Adoption Rates, Variety Attributes and Speed of Adoption
Provedor de dados: 31
Autores: Abele,   Steffen; Twine,   Edgar; Ntawuruhunga,   Pheneas; Baguma,   Yonah; Kanobe,   Charles; Bua,   Anthony.
The transition out of extreme poverty and hunger in agrarian economies requires an understanding of how new agricultural technologies are adopted by poor farmers. In Uganda, improved germplasm from the cassava breeding program has generated new varieties that are increasingly being grown by farmers. Although considerable success has been achieved in adoption of these varieties in general, there is increasing pressure on breeding and technology dissemination programs to improve the targeting of their efforts. This paper identifies the specific cassava varieties adopted thus far and their desirable and undesirable attributes. In addition, it determines the adoption rates of these varieties and the factors that have influenced the speed of adoption of the...

Factors influencing adoption of conservation tillage in Australian cropping regions
Provedor de dados: 31
Autores: D'Emden,   Francis H.; Llewellyn,   Rick S.; Burton,   Michael P.
The purpose of this research is to improve understanding of conservation tillage adoption decisions by identifying key biophysical and socio-economic factors influencing no-till adoption by grain growers across four Australian cropping regions. The study is based on interviews with 384 grain growers using a questionnaire aimed at eliciting perceptions relating to a range of possible long- and short-term agronomic interactions associated with the relative economic advantage of shifting to a no-tillage cropping system. Together with other farm and farmer-specific variables, a dichotomous logistic regression analysis was used to identify opportunities for research and extension to facilitate more rapid adoption decisions. The broader systems approach to...

Upland crop technologies in Cambodia: economic evaluations and some adoption issues
Provedor de dados: 31
Autores: Farquharson,   Robert J.; Scott,   J. Fiona; Sareth,   Chea.
Agricultural research and development (R&amp;D) has being conducted in the upland districts of Cambodia to develop new farming systems and crop management technologies. Levels of farm income in these areas are relatively low due to small farm sizes and low crop productivity. Work is also planned to encourage the process of adoption of these technologies, and here we investigate how this process can be facilitated. A literature review identifies two important technology characteristics, ‘relative advantage’ and ‘trialability’, for successful adoption. Minimum or target rates of return on investment in new technologies are discussed as a means of investigating how much improvement in relative advantage might be enough to encourage successful adoption of the...

FARM-LEVEL DETERMINANTS OF CONVERSION TO SUSTAINABLE FARMING PRACTICES IN THE NEW MEMBERS STATES
Provedor de dados: 31
Autores: Cristoiu,   Adriana; Cobos,   Blanca Lucena; Caceres-Clavero,   Francisco.
A field survey carried out in 2005 in the Czech Republic and Lithuania to investigate the determinants of converting to organic farming reveals that farmer's own belief and the intrinsic characteristics of the farm increase the likelihood of conversion. If the process of certification as an organic farm implies important changes of the structure of the farm, it lowers the propensity of farmers to consider the conversion to organic. When considering the case of family farms, results of a logit model reveal that apart from farmers' own belief in the environmental or food quality benefits of organic farming, availability of information/own knowledge about the characteristics of technology to be adopted, availability of extra labour, and membership to farmers'...

The role of grazier motivations and risk attitudes in the adoption of grazing best management practices
Provedor de dados: 31
Autores: Greiner,   Romy; Miller,   Owen; Patterson,   Louisa.
The onus on landholders in relation to environmental performance is ever increasing. One tool for achieving environmental improvements is the design and promotion of region-specific ‘best management practices’ (BMPs). These are conservation practices aimed at reducing diffuse source pollution from agricultural lands and thus improving end-of-catchment water quality. A suite of grazing BMPs were developed for the Burdekin Dry Tropics region in a consultative fashion but without explicit consideration of knowledge of adoption processes. It is known from the literature that farmers’ goals and risk perceptions in particular influence adoption decisions. This paper utilises the data from an earlier grazier survey to explore to what extent grazier motivations...

An assessment of five different theoretical frameworks to study the uptake of innovations
Provedor de dados: 31
Autores: Botha,   Neels; Atkins,   Kris.
There are several theoretical frameworks one can draw upon to study the adoption process. Extension Theory, Bounded Rationality, Diffusion Theory, the Theory of Reasoned Action and Consumer Behaviour Theory were of particular interest to us. In assessing the frameworks we looked for contradictions, and how and whether these frameworks could be used to study the adoption process. The assessment was done by using our own conceptual framework of the adoption process and we discuss the results in this paper. We found that the different frameworks don‘t contradict each other and when combined into our conceptual framework they offer very useful constructs for studying the adoption process.

Determinants of Agricultural Technology adoption: the case of improved groundnut varieties in Malawi
Provedor de dados: 31
Autores: Simtowe,   Franklin; Asfaw,   Solomon; Diagne,   Aliou; Shiferaw,   Bekele A.
This paper applies the Average Treatment Effect (ATE) framework on data obtained from a random cross-section sample of 594 farmers in Malawi to document the actual and potential adoption rates of improved groundnut varieties and their determinants conditional on farmers’ awareness of the technology. The fact that not all farmers are exposed to the new technologies makes it difficult to obtain consistent estimates of population adoption rates and their determinants using direct sample estimates and classical adoption models such as probit or tobit. Our approach tries to control for exposure and selection bias in assessing the adoption rate of technology and its determinants. Results indicate that only 26% of the sampled farmers grew at least one of the...

SEQUENTIAL ADOPTION OF SITE-SPECIFIC TECHNOLOGIES AND ITS IMPLICATIONS FOR NITROGEN PRODUCTIVITY: A DOUBLE SELECTIVITY MODEL
Provedor de dados: 31
Autores: Khanna,   Madhu.
This paper analyzes the sequential decision to adopt two site-specific technologies, soil testing and variable rate technology (VRT), and their impact on nitrogen productivity in four Midwestern states. The results indicate that while farm location was a key variable influencing the adoption of soil testing, human capital and innovativeness of farmers had a significant impact on the adoption of VRT. A double selectivity model applied to correct for sample selection bias shows that gains in nitrogen productivity due to the two adoption decisions are largest for farms with below average soil quality and statistically insignificant for farms with above average soil quality. These findings have implications for the targeting of public policies designed to...

Autores: Bergtold,   Jason S.; Molnar,   Joseph J.
The paper examines the joint adoption of conservation tillage, crop rotations, and soil testing by small and limited-resource farmers in the Southeast. The objectives are to determine the potential eligibility of small farmers for the Conservation Security Program, examine socioeconomic factors affecting adoption, and assess the interdependence between adopting different conservation practices. Results indicate that conservation management, ethnicity, and farm characteristics affect practice adoption. Of the producers surveyed in the study, 7% meet Conservation Security Program eligibility requirements, while the other 93% have less than a 20% likelihood of adopting the needed practices to qualify.

Autores: Loizou,   Efstratios; Michailidis,   Anastasios; Tzimitra-Kalogianni,   Irene.
Over the last years, food safety, health and environmental issues are a few among many other reasons that force consumers to adopt new innovative food products – organic, private label, genetically modified and functional – as part of their consumption. This spectacular shift of the consumption forwards “innovative” food products attracts the interest of the analyst as it can shed new light on consumer’s behaviour and on modeling and understanding better his long-term behaviour. Thus, this study attempts to investigate the factors that influence consumer’s decision in purchasing either traditional or new innovative products and to what extend this shift between those two groups of products is related to pre-defined elements. This is achieved by employing...

ADOPT: a tool for predicting adoption of agricultural innovations
Provedor de dados: 31
Autores: Kuehne,   Geoff; Llewellyn,   Rick S.; Pannell,   David J.; Wilkinson,   Roger; Dolling,   P.; Ewing,   Michael A.
A wealth of evidence exists about the adoption of new practices and technologies in agriculture but there does not appear to have been any attempt to simplify this vast body of research knowledge into a model to make quantitative predictions across a broad range of contexts. This is despite increasing demand from research, development and extension agencies for estimates of likely extent of adoption and the likely timeframes for project impacts. This paper reports on the reasoning underpinning the development of ADOPT (Adoption and Diffusion Outcome Prediction Tool). The tool has been designed to: 1) predict an innovation‘s likely peak extent of adoption and likely time for reaching that peak; 2) encourage users to consider the influence of a structured...

This study applied logit and logit transformed regression to examine factors affecting the adoption of orange flesh sweet-potatoes (OFSP), and intensity of such adoption, by a representative sample of 340 farmers in the Busia and Rachuonyo districts of Kenya in 2009. The study also investigated whether participation in a value chain extension intervention programme increased these farmers’ likelihood of adopting OFSP. The results suggest that the district where the farmer comes from, knowledge on value addition and nutritional benefits, and availability of vines were the key factors for adoption. The results also suggest that participation in a value chain extension programme enhanced the probability of adoption. Factors affecting intensity of adoption...

Demographic and Management Factors Affecting the Adoption and Perceived Yield 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 direct and indirect costs and benefits. Farmers will adopt and utilize cover crops as long as the perceived benefit of using them is positive. This paper examines the demographic and management factors affecting the adoption and perceived benefit (in terms of improved crop yield) of using winter annual cover crops. A double selectivity model of cover crop adoption and perceived yield gain was estimated using survey data of Alabama farmers examining cover crop use and management.  Results may help in understanding factors shaping farmers’ perceptions, adoption, and retention of cover crops.

The adoption of environmental management practices is addressed in this paper. The use of consumer behaviour theory and a market research approach is discussed by describing how it was used in the study. Qualitative methods were used to gather data from dairy farmers in four New Zealand catchments. The environmental practices explored were; excluding stock from waterways, reducing phosphorus use, improving soil macroporosity, managing effluent and improving the efficiency of border-dyke irrigation. The findings are discussed, highlighting that farm contextual factors influenced farmers’ decision making in terms of adopting environmental management practices. The results suggest that environmental practices need to be linked to farm context. This should...

Adoption of precision agriculture technology has arrived considerable attention, but abandonment has received little.  This paper identified factors motivating adoption and abandonment of precision soils sampling in cotton.  Younger producers who farmed more cotton area, owned more of their cropland, planted more non-cotton area, or used a computer 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, or used variable-rate fertilizer application were less likely to abandon precision soil sampling.

Autores: Field,   Alfred J.; Field,   Erica Marie; Torero,   Maximo.
The period of 1994 to 2004 was one in which rural households in Peru experienced dramatic changes in ownership rights through a large nation-wide land titling program and a significant opening of the economy to international trade. This paper takes this prime opportunity to examine whether lack of ownership rights presents a significant barrier to the adoption of commercial crops and/or modern farming practices as a result to changes which reduced domestic market distortions, opened up the economy and thereby presumably altered relative prices between traditional agricultural crops and those produced primarily for export. To the extent that participation was quasi-exogenous to other household features influencing production choices, the titling program...

Citrus is the leading fruit of Pakistan and famous worldwide especially kinnow cultivar because of its pleasant taste and remarkable quality. The yield of citrus per hectare in Pakistan is almost half of potential due to non-adoption of recommended horticultural practices by citrus growers. Adopting a decision regarding the improvement of practices is usually influenced by various factors including farmers' socio-economic attributes. In order to determine the relationship between socio-economic aspects and the awareness and adoption of recommended citrus production practices the present study was carried out in Sargodha district from central Punjab, Pakistan.
