Betting on cotton: Potential payoffs and economic risks of adopting transgenic cotton in West Africa AgEcon
Falck-Zepeda, Jose Benjamin; Horna, J. Daniela; Smale, Melinda.
Cotton is the largest source of export receipts in several West African nations where yields are declining and pesticide use is rising. Although there may be payoffs to introducing genetically modified Bt (Bacillus thurigiensis) cotton, limited information is available to predict its potential economic impact and there is uncertainty about its performance. Recognizing these constraints, we use an economic surplus model augmented with stochastic simulation to estimate ex ante the impact and distribution of benefits from Bt cotton. We consider the effects of adoption on both yields and abating crop damage, and offer scenarios depicting the policy options faced by West African stakeholders. The findings indicate that although the total net benefits of...

Cotton Production in Uganda: Would GM technologies be the Solution? AgEcon
Horna, J. Daniela; Kyotalimye, Miriam; Falck-Zepeda, Jose Benjamin.
The government of Uganda is currently testing the performance of genetically modified (GM) cotton varieties. Cotton is cultivated in Uganda for two main reasons: 1) agro-ecological conditions favor cotton cultivation, and 2) there is a long tradition of cotton cultivation in the country. Two main research questions are addressed in this study: a) would the adoption of genetically modified (GM) cotton benefit Ugandan farmers? b) Would the use of GM seed be more profitable than the low input traditional system or than the organic production system? Stochastic budget analysis is used to address these questions. The results show that estimated values of cotton profitability do not seem to justify the investment in a complex technology. The question then is how...

Farmer Willingness to Pay for Seed-Related Information: Rice Varieties in Nigeria and Benin AgEcon
Horna, J. Daniela; Smale, Melinda; von Oppen, Matthias.
A typical private good is defined by its excludability and rivalry characteristics. Information embodied in a technology might not generate rivalry among its users. By contrast, excludability is certainly a characteristic of this kind of information and its delivery can generate incentives for private participation. This study examines farmers’ preferences for seed of new rice varieties and their willingness to pay for seed-related information in villages of Nigeria and Benin. Conjoint analysis is used to estimate the structure of farmers’ preferences for rice seed given a set of alternatives. Farmers are considered to be consumers of seed as a production input, preferring one variety over another based on the utility they obtain from its attributes, which...

From "best practice" to "best fit" a framework for designing and analyzing pluralistic agricultural advisory services worldwide AgEcon
Birner, Regina; Davis, Kristin E.; Pender, John L.; Nkonya, Ephraim M.; Anandajayasekeram, Ponniah; Ekboir, Javier M.; Mbabu, Adiel N.; Spielman, David J.; Horna, J. Daniela; Benin, Samuel; Cohen, Marc J..
The paper develops a framework for the design and analysis of pluralistic agricultural advisory services and reviews research methods from different disciplines that can be used when applying the framework. Agricultural advisory services are defined in the paper as the entire set of organizations that support and facilitate people engaged in agricultural production to solve problems and to obtain information, skills and technologies to improve their livelihoods and well-being… To classify pluralistic agricultural advisory services, the paper distinguishes between organizations from the public, the private and the third sector that can be involved in (a) providing and (b) financing of agricultural advisory services. The framework for analyzing pluralistic...

Insecticide Use on Vegetables in Ghana: Would GM Seed Benefit Farmers? AgEcon
Horna, J. Daniela; Smale, Melinda; Al-Hassan, Ramatu M.; Falck-Zepeda, Jose Benjamin; Timpo, Samuel E..
Tomato, cabbage and garden egg (African eggplant, or Solanum Aethiopicum) are important crops for small-scale farmers and migrants in the rural and peri-urban areas of Ghana. Genetic modification (GM) has the potential to alleviate poverty through combating yield losses from pests and diseases in these crops, while reducing health risks from application of hazardous chemicals. This ex-ante study uses farm survey data to gauge the potential for adoption of genetically-engineered varieties, estimate the potential impact of adoption on farm profits, and highlight economic differences among the three crops. Farmer's expenditures on insecticides are below the economic optimum in all three crops, and the estimated function for damage abatement shows that...

PRIVATE PARTICIPATION IN AGRICULTURAL EXTENSION IN NIGERIA AND BENIN: DETERMINING THE WILLINGNESS TO PAY FOR INFORMATION AgEcon
Horna, J. Daniela; Smale, Melinda; von Oppen, Matthias.
A typical private good is defined by its excludability and rivalry characteristics. Information might not generate rivalry among its users. By contrast, excludability is certainly a characteristic of information and its delivery can generate incentives for private participation. This study examines farmers'’ preferences for seed of new rice varieties and their willingness to pay for related information in villages of Nigeria and Benin. Conjoint analysis is used to estimate the structure of farmers'’ preferences for rice seed given a set of alternatives. Farmers are considered to be maximizers of utility rather than profit, preferring one variety over another based on the utility they obtain from its attributes, which depends on their own social and...

Supporting Agricultural Extension: Could Farmers Contribute? AgEcon
Horna, J. Daniela; von Oppen, Matthias.
Is extension an effective tool for increasing social welfare? The objective of this study is to evaluate the feasibility of farmer financial participation in extension as an alternative to increase its efficiency. While extension costs have been high, the impact at farmers' welfare has not yielded the expected results. Rice production in Nigeria and Benin is used as a study case. Rice is an important food crop and cash crops and both countries have conditions to produce it locally. Two concepts are used to evaluate private participation: farmers' capability to pay (CTP) and requirement to pay (RTP) for extension. Farmers' capability to pay is evaluated from the expected increase benefit due to extension work. Requirement to pay is deducted from extension...

The Economic Impact and the Distribution of Benefits and Risk from the Adoption of Insect Resistant (Bt) Cotton in West Africa AgEcon
Falck-Zepeda, Jose Benjamin; Horna, J. Daniela; Smale, Melinda.
Cotton is the largest source of export receipts of several West African countries. Statistics however show a decreasing tendency in cotton yields and an increasing tendency in pesticide use. Under this circumstances there appear to be potential payoffs from the use of biotechnology products in the farming systems of the region. In this study we estimate different scenarios for the potential deployment of insect resistant cotton in selected countries in West Africa (WA). We use an economic surplus model augmented with a more rigorous sensitivity analysis of model parameters. Hypothetical scenarios of Bt cotton adoption in WA are simulated and single point values of model parameters are substituted with probability distributions. The scenarios include: no...

Vegetable Production and Pesticide Use in Ghana: Would GM Varieties Have an Impact at the Farm Level? AgEcon
Horna, J. Daniela; Timpo, Samuel E.; Al-Hassan, Ramatu M.; Smale, Melinda; Falck-Zepeda, Jose Benjamin.
The objective of this study is to evaluate pesticide use as an important factor affecting potential adoption and farm level impact of genetically modified (GM) vegetable varieties in Ghana. Tomato is the most consumed vegetable and a food security crop. Cabbage is a vegetable of growing importance but limited cultivation and is produced in urban areas. Garden egg is a native African crop of wide consumption and importance for rural economies. Farm level information was collected in randomly selected sites in southern and central regions of Ghana. Partial budget analysis shows that investments in pesticides are rather low, especially for tomato and garden egg. Analysis of production using an abatement framework shows that insecticide amounts are significant...
