In order to facilitate Participatory Technology Development (PTD) in African agriculture, extensionists and scientists must collaborate with local innovators to optimise (where necessary) and disseminate their innovations. This literature review proposes a conceptual model for PTD in which technology is developed in the context of an adoption cycle. Building on an innovation-decision approach, the characteristics of innovations that achieve widespread uptake are identified.
This review's objectives were to examine the structure and performance of the agricultural research and extension systems (public and private) at the central and provincial levels, identify successes as well as constraints to improving the system s effectiveness for fostering innovation, and propose options for further policy and institutional development, drawing on lessons from international experience. The review focused principally on nonplantation crops, although its main recommendations apply across the agricultural sector.
