Agricultural productivity in Africa from 1971 to 2000 is examined using the recently developed metafrontier function technique, for the purpose of studying differences in efficiency and technology gap across different regions of the continent. The results support the view that technology gap play...

Since 1991, there have been significant changes in utilisation of feed resources in the Ethiopian highlands: while use of communal grazing lands and private pastures has declined, use of crop residues and purchased feed has increased. In addition, although use of animal health services, and adopt...

Recent studies have reported the benefits of fertilizer microdosing in increasing crop yields in low input cropping systems. Little information is however available on the mechanisms underlying this effect. The objective of this study was therefore to explore the root-based mechanisms governing t...

Crowdsourcing crop improvement in Sub-Saharan Africa: a proposal for a scalable and inclusive approach to food security.
Based on analysis of credit supply in Ethiopia, Kenya, Uganda and Nigeria, it is shown that public credit institutions do not have sufficient funds to meet the demand for livestock credit and cannot mobilize savings from their clients or other commercial sources for one reason or another. In addi...
