Abstract

The traditionla practice of shifting cultivation in West Africa, as described by Nye and Greenland (1960), is an effective system of restoring soil fertility only where pressure on the land is minimal. With increasing population growth and a concomitant requirement for increased food production, fallow periods are shorter and crop yields low.
