Synthesis of the Standing Panel on Impact Assessment's (SPIA) study of the impacts of CGIAR germplasm improvement research prepared by Robert Evenson and Douglas Gollin, and presented at the 2001 Mid Term Meeting by SPIA Chair Hans Gregersen. The study documented the development and diffusion of over 8,000 modern varieties in eleven major crops between 1965 and 1998, and the proportion of new varieties directly or indirectly attributable to the work of international agricultural research centers (IARCs). Using counterfactual analysis, the study examined the impacts of these modern varieties on productivity, food prices, and child nutrition, and the contributions of IARC-produced genetic materials provided to national agricultural research. It also examined the causes of wide variations between regions in the adoption and rates of adoption of the modern varieties. The full report of the SPIA study was scheduled for publication by CAB International towards the end of 2001 under the title 'Crop Variety Improvement and its Effect on Productivity: The Impact of International Agricultural Research.'
