This volume offers substantive clarification of the proper roles for public agricultural research and development (R&D) throughout Latin America and the Caribbean (LAC) and introduces an analytical framework for assessing cross-country collective action in funding and carrying out research. To...

This paper examines the ex-ante benefits of transgenic research on drought in eight developing countries, including the potential magnitude of private sector profits. The framework employs country-specific agroecological-drought risk zones and considers both yield increases and yield variance...

Purpose: The purpose of this paper is to estimate shadow prices of agricultural carbon emissions produced by agricultural inputs, rice paddy and burning crop residue, and to explore the impact of cropping pattern on marginal abatement cost (MAC). Design/methodology/approach: The shadow price of...

Purpose: The purpose of this paper is to examine the status of the supply reliability of groundwater irrigation, and discuss how it is affected by climate change and tubewell density in rural China. Design/methodology/approach: This study is based on a nine-province village survey and secondary...

Coffee is the most important export crop in Uganda and an important source of income for smallholder farmers in large parts of the country. The paper first investigates the challenges and opportunities faced by the Ugandan coffee industry, especially the decline in the world coffee market,...

The concentration of crop cultivation can be measured in terms of spatial clustering and of inequality in the distribution of the cropland area. We used official agricultural statistics at the county level (N = 2,354) for each year from 1980 to 2011 for all of China to analyse the changes in...
