摘要：It is widely believed that a Green Revolution similar to the one achieved in Asia is impossible in Sub-Saharan Africa. Although grain yields have been stagnant in this region, there are some signs of the intensification of farming systems in the face of growing population pressure on limited land resources. In this paper we focus on the new farming system based on the use of manure produced by dairy cows, which may be termed an “Organic Green Revolution.” Using the farm household data collected from Kenya, this paper demonstrates that the Organic Green Revolution has a potential of doubling maize yields in highlands of Kenya.
