Description: Das Projekt "The economics of on-farm conservation of crop diversity in Ethiopia: incentives, attribute preferences and opportunity costs of maintaining local varieties of crops" wird vom Umweltbundesamt gefördert und von Universität Bonn, Institut für Lebensmittel- und Ressourcenökonomik (ILR), Professur Ressourcen- und Umweltökonomik durchgeführt. Water, soil, air and genetic resources are the four major natural resources that society depends upon for food, clothing, shelter, and medicament. The sustainable use and conservation of biological resources is a topical research, conservation and development issue. Ethiopia is among the economically poor countries but still rich in biological diversity. Even though the country has an enormous genetic resource stock, the diversity is dwindling due to technologyinduced incentive forces. Among the different ex situ and in situ options for conserving these resources, conservation on farmers fields has recently received a considerable attention by governments, NGOs and the international community. Many issues regarding its implementation are yet unknown though. Since farmers are the major actors in on-farm conservation, their contribution to crop diversity and the role of diversity to their livelihoods have to be understood. Hence, the principal objectives of the study are to: - examine the farm household related contextual factors motivating farmers to diversify on local varieties; - study farmers variety attribute preferences and examine their demand forlocal varieties; and - quantify the opportunity costs of growing local varieties and analyze thecontextual factors affecting the opportunity costs. To address its objectives, the study uses household survey data from Ethiopia concerning coffee, sorghum and wheat. It examines the above objectives using a variety of microeconomic theories (like the characteristic model, the random utility theory, theory of impure public goods, and the theory of joint production) and econometric techniques (like poisson regression, multinomial logit and switching regression). The results show that local varieties are maintained de facto mainly by poor, subsistent and marginalized farmers with limited access to markets, roads, and extension. Farmers multiple concerns, yield insurance considerations, land heterogeneity, relative importance of sorghum and coffee, and labor endowment have been found to be the most important factors promoting the use of multiple varieties of local varieties. On the contrary, farmers experience in improved varieties is found to be detaching the link between de facto on-farm conservation and household livelihood strategies. The attribute preference analysis shows that farmers in more accessible (to markets and road) areas with less income-shock vulnerability conserve high yielding and marketable varieties de facto. On the contrary, varieties with more stable yield and environmentally adaptable features are most demanded by farmers with higher income-shock vulnerability found in less accessible localities. usw.
