Perception paysanne et adoption des biopesticides et/ou extraits botaniques en production maraîchère au Bénin AgEcon
Adekambi, Souleimane Adeyemi; Adegbola, Patrice Ygue; Arouna, Aminou.
The importance of farmers’ perceptions of characteristics on agricultural innovation adoption has increased these two decades. Empirical studies revealed that in addition to farmers’ socioeconomic characteristics and institutional factors, farmers’ perceptions of the innovation-specific characteristics are particularly important in determining whether or not to adopt them. This study assessed vegetables farmers’ perceptions of botanical extracts and biopesticides compared with current chemical pesticides. It also examined the relationship between farmers’ perceptions and the adoption of botanical extracts and biopesticides. Data were collected from a stratified randomly sample of 198 vegetables farmers selected in vegetable producing zones in Benin and...

Pesquisadores, agricultores e ciência. Repositório Alice
MACEDO, M. M. C..
Este trabalho analisa a relacao entre a geracao e a adocao de duas tecnologias geradas pela Empresa Brasileira de Pesquisa Agropecuaria-Embrapa. Cento e quarenta e quatro agricultores e sete pesquisadores foram entrevistados no estudo de caso da cenoura 'Brasilia' (um produto de uso alimentar e comercializado no mercado interno) e da soka 'Doko' (um produto de uso industrial e dirigido para o mercado externo). Em ambos os casos, os dados foram coletados na regiao do Cerrado, uma fronteira agricola altamente subsidiada pelo governo. Os resultados indicaram que ambas as variedades foram adotadas pelos agricultores, aumentaram a produtividade, foram tolerantes a algumas doencas e aumentaram os lucros dos produtores. Elas foram geradas por pesquisadores...

Policy-Induced Technology Adoption: Evidence from the U.S. Lead Phasedown AgEcon
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...

Property rights and crop choice in rural Peru, 1994-2004 AgEcon
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...

Re-considering Agri-Environmental Schemes premiums: the impact of fixed costs in sign-up decisions AgEcon
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...

SEQUENTIAL ADOPTION OF SITE-SPECIFIC TECHNOLOGIES AND ITS IMPLICATIONS FOR NITROGEN PRODUCTIVITY: A DOUBLE SELECTIVITY MODEL AgEcon
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...

Socio-economic determinants of the awareness and adoption of citrus production practices in Pakistan Ciência Rural
Ashraf,Saleem; Khan,Ghazanfar Ali; Ali,Shoukat; Iftikhar,Muhammad.
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. The Study was based upon cross sectional survey research design due to availability of sampling...

SOCIO-ECONOMIC IMPACT OF BIOTECHNOLOGY APPLICATIONS: SOME LESSONS FROM THE PILOT TISSUE-CULTURE (TC) BANANA PRODUCTION PROMOTION PROJECT IN KENYA, 1997-2002 AgEcon
Mbogoh, Stephen G.; Wambugu, Florence M.; Wakhusama, Sam.
This article is based on a socio-economic impact study of the introduction and adoption of tissue-culture (tc) technology in banana production in Kenya. It attempts to demonstrate that a prudent introduction and promotion of a new biotechnological innovation in farming can make a positive contribution to the socio-economic status of resource poor farmers in a developing country, such as Kenya. Adoption of tc technology in banana production in Kenya is considered a good example of biotechnological applications in agriculture. Hence the article hopes to make a contribution to recent debates at international levels as to whether biotechnology can make a difference in uplifting the living standards of people in the third world (Qaim, 1999; Graff, et al 2002;...

Spread of retailer food quality standards: An international perspective AgEcon
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.

Taux et déterminants de l’adoption des technologies agricoles : cas des AgEcon
Adegbola, Patrice Ygue; Adekambi, Souleimane Adeyemi.
In spite of the socio-economic importance of yam, his production is still facing serious constraints as no availability and inadequacy of seed tubers. In order to cope with these constraints, International of Tropical Agriculture (IITA) has developed improved varieties of which we have TDrs’ varieties. Many years after their extension in Benin, it’s then important to evaluate their adoption rate and identify factors which determine this adoption. This study’s aim is to contribute to this evaluation. Data used came from 202 yam producers randomly selected in villages pertain to Borgou and Collines’s regions. The framework developed by Reed et al. (1991) and the counterfactual outcomes framework estimating the Average Treatment Effect have been respectively...

Technology Adoption And Pest Control Strategies Among UK Cereal Farmers: Evidence from Parametric and Nonparametric Count Data Models AgEcon
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...

Technology and Productivity: A Summary of the Relationship and a Review of Relevant Research AgEcon
Emter, Nicholas A..
This information bulletin is presented in two sections, which follow a summary of the key findings. The first section addresses the important contribution of productivity to economic growth and explores the relationship between adopting advanced technology and improving productivity. Drawing from the findings of productivity research, the section begins by defining productivity and explains why labour factor productivity is the best measure of, and the key to, productivity enhancement. It then explains how increasing productivity leads to economic growth and a higher standard of living. The section concludes by examining the relationship between adopting advanced technologies and productivity enhancement as shown through a review of relevant research...

THE BLENDING OF PARTICIPATORY RESEARCH AND QUANTITATIVE METHODS: WEALTH STATUS, GENDER AND THE ADOPTION OF IMPROVED FALLOWS IN ZAMBIA AgEcon
Franzel, Steven Charles; Phiri, Donald; Mafongoya, Paramu; Jere, Isaac; Katanga, Roza; Phiri, Stanslous.
Although there is increasing emphasis on targeting of improved technology towards poor and female farmers, few adoption studies assess the uptake of new practices by these groups in a comprehensive manner. In this study, community members used the wealth ranking method to identify the different wealth groups in their communities, to determine each household's wealth status, and to assess the association of wealth and different types of households with the planting of improved tree fallows, a practice for improving crop yields. There were no significant differences between the proportions of women and men planting improved fallows nor were there differences between single women and female heads of households who were married. There was some evidence of...

The Economics of Nested Insurance: The Case of SURE AgEcon
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...

The Effect of Information and Market Access on Adopters' Income Level AgEcon
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.

The Effect of Social Capital on the Choice to Use Sustainable Agricultural Practices AgEcon
Munasib, Abdul B.A.; Jordan, Jeffrey L..
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.
