This was a private public partnership funded by nine East African companies and the German Ministry for Economic Cooperation and Development through DEG. Using nine 10 hectare test sites across East Africa, the three year research programme aimed to contribute to understanding which types of Jatropha give the best yields under which conditions and sustainable management practices. Jatropha Support Programme seeks to answer: Is it economically viable to grow Jatropha as a sustainable biofuel feedstock in East Africa.
