Improved Fallows in Kenya: History, Farmer Practice, and Impacts

This case study explores the development, dissemination, adoption, and impact of improved tree fallows in rural western Kenya. The processes of technology development and dissemination throughout the region are described and analyzed. To analyze adoption and impact, the paper applies a variety of different data collection methods as well as samples from both pilot areas where researchers maintained a significant presence and non-pilot areas where farmers learned of the technologies through other channels. Technical support offered and study the adoption/non-adoption of agroforestry. Part of the study measure the impact on yield and economic return of 3 different fallow types vs continuous crop.
