Kenya's croton tree touted as new biofuels crop.

Mike Jacobson, professor of forest resources, says seeds from the croton tree could provide a good source of sustainable biofuel for east Africa.

Will croton ever become a global biofuel? It's doubtful, says Jacobson. But he adds that if local entrepreneurs persevere and oil prices go up again, this unlikely cash crop could make a real dent in east Africa's energy supply, "which alone is good enough."

Jacobson did a survey of subsistence farmers in five Kenyan counties, in dozens of villages, related to their willingness to plant croton trees and collect the nuts. His report encouraged the scaling up of the croton biofuel production.
