This paper addresses issues surrounding measurement of the potential productivity gains from new livestock tech- nologies and the returns to international livestock research. The approach, applicable to many livestock production constraints and technologies, uses geographic information systems (GIS) to spatially link a biophysical herd simulation model with an economic surplus model. The particular problem examined is trypanosomosis in cattle in Africa, and the potential research product is a multi-component vaccine. The results indicate that the potential benefits of improved trypanosomosis control, in terms of meat and milk productivity alone, are $288 million, with an internal rate of return of 33%, and a benefit/cost ratio of 34:1 .
