This study illustrates how productivity impacts resulting from livestock research can be measured using a herd simulation model, how the results of this model can be extended spatially using geographic information systems (GIS) to determine the potential increase in livestock production that would result from adoption of a new technology, and how an economic surplus model can be used to value the estimated productivity impacts. The particular problem examined is trypanosomosis in cattle in Africa, and the potential research product is a multi-component vaccine. The results suggest that the potential benefits of trypanosomiasis control, in terms of meat and milk productivity alone are worth over US$ 700 million per year in Africa. The methodology developed in this study can be used to measure the benefits of alleviating constraints to livestock production and the potential returns to research and development approaches addressing those constraints. The results of this study will assist in research priority setting and have highlighted the need for further research aimed at better understanding who the beneficiaries of the vaccine will be, and how it will reach them.
