The purpose of this research is to study the determinants of farm-level variety choice and variety demand for banana cultivars in Uganda within an integrated agricultural household modeling framework. Of particular interest is the role of banana consumption and production attributes, among other factors, in influencing the scope of the household planting decision. A revealed preference for a particular banana variety encompasses a set of underlying household, market and agro-climatic characteristics that influence farm-level decisions. It is also associated with farmers? perceptions of the intrinsic consumption and production attributes (or specific genetic traits) embodied in the chosen variety and attribute trade-offs that this entails. The model of variety choice developed here provides the analytical means for conceptualizing the interdependence of household production and consumption decisions at the level of attributes inherent to specific varieties grown. The econometric approach used for estimating the set of individual variety demand equations is the Heckman two-step procedure for count data models - the Poisson and the Negative Binomial - that take into account potential sample selection problems. The results indicate that the factors that significantly influence the growing decision (variety choice) and the extent of growing (variety demand) are cultivar-specific, with differences between endemic and non-endemic cultivars, and within the endemic group of cultivars. Production attributes are found to be jointly important to the extent of the planting decision, while the consumption attribute taste is significant for only the non-endemic cultivars. The existence of separability between consumption and production decisions is ambiguous when using the conventional approach, while it appears to hold in the case of endemic cultivars when the attribute approach is employed. Participation in banana markets is found to not only be household-specific, but also cult.

This paper investigates the relationship between adoption of modern rice varieties and rice varietal diversity on household farms in Bangladesh. As shown in previous studies, adoption of modern varieties depends on agroecological- and input-related factors, including the availability and use of irrigation facilities, such as tubewells. Having irrigation affects the diversity index significantly and positively, which could be due to the diffusion of more modern varieties (MVs) in areas where irrigation is available and accessible.

This book examines the challenges faced by farmers trying to maintain crop biodiversity in developing and transitional economies. Using a collection of empirical case studies of farmers and crop scientists across a range of agricultural economies and income levels, it presents economic tools and methods for valuing and managing crop biodiversity. It discusses the economic benefits of crop biodiversity for farmers and suggests ways in which crop biodiversity can be supported by national policies. The book provides an indispensable 'tool kit' for all those concerned with the development of strategies to facilitate sustainable management and conservation of crop genetic diversity for future generations.

A variable climate, political instability, and other constraints have limited agricultural development in African countries south of the Sahara. Genetically modified (GM) crops are one tool for enhancing agricultural productivity and food security despite such constraints. Genetically Modified Crops in Africa: Economic and Policy Lessons from Countries South of the Sahara investigates how this tool might be effectively used by evaluating the benefits, costs, and risks for African countries of adopting GM crops. The authors gather together studies on GM crops economic effects and impact on trade, how consumers view such crops, and other issues. They find that GM crops have had, on average, a positive economic effect in the nations where they were used and identify future steps for enhancing GM crop adoptions positive effects. Promising policy initiatives include making biosafety regulations that do not make GM crop development prohibitively expensive, fostering intraregional trade in GM crops, and providing more and better information about GM crops to consumers who might currently be skeptical of them. These and other findings in Genetically Modified Crops in Africa indicate ways biotechnology can contribute to economic development in Africa south of the Sahara.
