Abstract:
The bulk of studies on farm productivity were done in the 1960s and 1970s before land became constraining. Our understanding of African farm productivity needs to be updated to see how farmers are responding to recent policy, economic, and environmental changes. We aim in this report to “dig below” aggregate trends to uncover differences in patterns and determinants of productivity over agroclimatic zones, types of technology, degrees of environmental degradation, and levels of improved inputs. The report synthesizes studies in four countries. The Burkina Faso, Rwanda, and Senegal studies use detailed farm-survey data from the past decade. The Zimbabwe study uses aggregate data from the past two decades which is stratified by farm type (commercial and smallholder).
