Feeding a growing population and responding to changing markets requires innovation in agriculture. The expectations of the contribution of agricultural research to innovation are high. This paper looks at the process of agricultural innovation and the realistic contribution agricultural research can make.
Value chain development approaches seldom deliver large scale impact. Based on the examination of five cases where impact at scale was realised, recommendations are offered to increase the chances of value chain interventions contributing to impact at scale.
