Kenya's hope that biofuel will reduce poverty

The jatropha tree is being harvested to create biofuel in Kenya. The product can be used to fuel anything from aircrafts to cookers and the new industry is being billed as a way out of poverty for many of the country's poor. However, a lot of land is needed to create the fuel. Al Jazeera's Yvonne Ndege reports from Kitui in eastern Kenya.
