This chapter describes the impact of national agricultural research systems on the unfolding of the Green Revolution in four regions: Asia, Latin America, the Middle East and North Africa, and Sub-Saharan Africa. Although international institutions contributed much of the research that led to...

In this chapter we compute measures of total factor productivity (TFP) growth for developing countries and then contrast TFP growth with technological capital indexes. In developing these indexes, we incorporate schooling capital to yield two new indexes: Invention-Innovation Capital and...

This survey reviews the existing literature, identifying the contribution of agriculture, schooling, and nutrition to economic growth and development over time and across countries. Particular attention is paid to the roles of improvements in agricultural technology and of the human capital of...

Since at least the time of von Thunen's contributions to the subject, economists have been interested in explaining land use in the hinterlands. This interest has grown with increasing societal demands on remaining forested areas and concern for the nonmarket resources generated by such...

This chapter traces the evolution of the agricultural economics literature on agrifood output markets over the past 50 years, emphasizing research approaches and policy issues. The analysis of agrifood systems encompasses the demand and supply side of output markets. The analysis in this chapter...

In this chapter we analyze the considerations that lead policy makers to undertake extension investments as a key public responsibility, as well as the complex set of factors and intra-agency incentives that explain why different extension systems' performance varies. Accordingly, the chapter...

This paper examines the likely impact on agriculture of the climate change which has already taken place between 1960 and 2000. Accumulating greenhouse gases have caused global temperatures to rise approximately 0.25[thin space][degree sign]C during this period and for precipitation patterns to...

Demand for fertilizer in developing countries has expanded at a rapid rate over the past forty years. The relative scarcity of agricultural land has been a major underlying cause of this expansion in demand. More proximate causes include the development of complementary Green Revolution...

This chapter serves to assess the quantity and impact of private agricultural research in developing countries, alongside the policies which affect that research. To provide context, an outline of the history, size and structure of private research presents data on research expenditures by...

Over the past half a century developing regions, with the exception of Sub-Saharan Africa, have seen labor-saving technologies adopted at unprecedented levels. Intensification of production systems created power bottlenecks around the land preparation, harvesting and threshing operations....
