Abstract

The foundation for agriculture’s role in economic transformation is largely public modern science institutions producing a steady flow of improved technology. That technology must be locally based to ensure suitability to highly variable local conditions. Agriculture stands out relative to other sectors in the centrality of modern science to its progress. Research results must reach farmers and farmers’ requirements must feed back to research. As a result, research and extension must be tightly integrated. The research system is also the repository of the best technical knowledge and all the other institutions feed off of it. It is central to rapid agricultural growth, which is usually underinvested, and often grossly so.
