"The Diffusion and Productivity Impact of CGIAR-related Crop Improvement Technologies Since 1960" by Fuglie, Keith Abstract This paper provides a meta-analysis of the diffusion and productivity impact of the crop improvement programs of the CGIAR system of international agricultural research centers. Assembling evidence from hundreds of field studies on adoption of CGIAR-related technologies and using interpolation methods, we construct a time path for the diffusion of improved varieties and cultural practices for 20 field crops across developing countries. Estimates of changes in crop yield and production costs resulting from adoption of first and subsequent generation modern crop varieties are also developed. Together, this evidence provides the most comprehensive assessment of the productivity impact of crop improvement research by the CGIAR system to date. By 2016-2020, these technologies had been adopted on 225 million hectares and had generated net productivity gains of $52 billion per year. Sixty percent of this impact had occurred in East, South and Southeast Asia, 25% in Sub-Saharan Africa, 11 percent in Latin America, and 4% in Central & West Asia and North Africa. |
