More than half the world’s population depends primarily on biomass fuel (biofuel) for domestic purposes (United Nations, 1988). As long as there is no degradation of the vegetation, the biofuel system makes no net contribution to change in atmospheric C02 and little damage to the upland environment. As a result, ecologists are increasingly interested in successful experiences in biofuel harvesting as a sustainable development and with their impacts on the upland environment, although there have been very few studies in this field.
