This paper investigates the impacts of population growth, market access, agricultural credit and technical assistance programs, land policies, livelihood strategies and other factors on changes in land management, natural resource conditions and human welfare indicators since 1991 in the...

"On farm conservation of crop diversity poses obvious policy challenges in terms of the design of appropriate incentive mechanisms and possible trade-offs between conservation and productivity. This paper compares factors explaining the inter-specific diversity (diversity among species) and...

On farm conservation of crop diversity poses obvious policy challenges in terms of the design of appropriate incentive mechanisms and possible trade-offs between conservation and productivity. This paper compares factors explaining the inter-specific diversity (diversity among species) and...

On farm conservation of crop diversity entails policy challenges, especially when the diversity of crops maintained on farms has both inter-specific (among crops) and infra-specific (within a crop) components. Survey data is used to compare the determinants of inter- and infra-specific diversity...

This chapter assesses livestock productivity in the developing world in the context of growing demand for livestock products and substantial changes in the structure of food demand, commercialization of production, and growing importance of international markets. Issues related to the roles of...

Short-term land leases have an important role to play for efficient land management and agricultural development, especially when land sales and mortgages are prohibited and markets for other factor inputs are imperfect or missing. This study utilises data from the highlands of northern Ethiopia...

This paper examines the factors contributing to decline in ownership of various types of livestock and availability and quality of grazing lands in the northern Ethiopian highlands since, 1991. It also examines the factors contributing to changes in utilisation of various feed resources....

Conventional estimates of the economic return to agricultural research use market prices for the values of products and inputs; on this basis, economic rates of return are typically well above the cost of capital, suggesting that more investment in research would be socially desirable. But these...
