Croton nuts -- 001

Croton nuts -- 001

Michael Jacobson

Penn State researcher Michael Jacobson surveyed small-holder farmers in villages across four counties in Kenya about their willingness to grow croton trees. He asked them such things as how many trees they have, whether they would be willing to plant more, and whether they would gather the nuts and provide them to a biofuel-making company at collection points and, if so, at what price.
