Abstract:
|
"The Sahel is threatened with a medium-term ecological crisis that stems mainly from bad agricultural and pastoral practices. Faced with this crisis - which includes serious shortages of fuelwood for household needs - foresters have reacted by establishing plantations of exotic species of trees for fuelwood needs. These plantations are designed to be set up and maintained with machinery for clearing land and working the soil. Machinery will have to be imported and the machines in turn will require imported fuel, all to be paid for with scarce foreign exchange. The question is, will not Sahelian forestry consume too much energy for the sake of creating energy? It is not a simple question to answer. Its answer, which this article attempts to give, may also be useful beyond the Sahel, anywhere in the world where similar ecological, economic and human factors exist in combination."
