An economic opportunity for some 905 small farmers from the semi-arid area in Kibwezi, Kenya, has been opened, as they learn to cultivate Jatropha curcas, under the “Trees for Clean Energy” program. Jatropha produces a non-edible oilseed which has been identified as a potential feedstock for future biodiesel production. Jatropha can be used in marginally productive lands (like in arid/semi-arid zones) due to its drought resistance, and it does not have negative impacts on the food chain. The program has been initiated by Kenyan agricultural scientist, Zaglon Waballa, in an effort to improve income of small farmers while tackling the reduction of greenhouse gas emissions..
