Alternative to charcoal helping protect gorilla habitat. Good to see this appropriate technology in use and all credit to the teams currently promoting it.
During a prolonged lull in the security mayhem of this central African hotspot a few years ago, the International Gorilla Conservation Programme and partners were presciently addressing this problem - setting up a buffer of trees around the Park and monitoring fuelwood use. (Building on the local networks of a health education charity, a "social marketing" campaign distributed both condoms and tree seedlings - and was irreverantly dubbed "pricks and sticks" by the team!) This living buffer of young trees was obliterated by waves of refugees and rising population levels, but perhaps reduced the severity of destruction and left some knowledge in its wake.
