Technology, location and trade: Kenyan vegetables

Abstract Agricultural research impacts in sub-Saharan Africa are often location specific and arise through a lengthy process of technology generation and adoption. A framework for technology assessment is presented which clearly demarcates the spatial and temporal dimension of potential research benefits, but is also compatible with broader research planning efforts and available human resources. Application to Kenya Agricultural Research Institute brassica and snap bean research themes demonstrates that location-specific commodity production base, the potential for technology generation, and the potential for technology adoption are important determinants of research impact. Commodity market structure and rapid population growth also influence the magnitude and distribution of research benefits.
