Two imperatives form the basis of the present paper. The first is the market-driven imperative, vital to production and value-chain development. The second is the knowledge imperative, central to the advancement of human capacity and institutional development. In view of these two imperatives, this paper argues for overhaul in extension toward a market orientation and for greater public investment in human resource development for modernizing the agricultural extension workforce. Part one of the paper reviews the rationale for market-driven extension and compares two key market-driven strategies. Part two proposes changes and new investment in post-secondary agricultural education and training, and calls for the establishment of a network of post-secondary agricultural education and training institutions. A post-secondary educational network is seen as essential to better prepare the agricultural extension workforce to face challenges in production and marketing and beyond with respect to alternative programs such as agriculturally related urban, environmental, energy, and rural development priorities.
