%X Changes in village farming systems brough about by population growth and continuing low rainfall, are described for the three main agro-ecological zones in Burkina Faso. The toposequential landuse and cropping patterns were used as the basis for a model, which describes the long-term ecological degradation from declining proportions of fallow land and over-cropping. The implications of these changes for land tenure systems have also been considered. The result provide a human and ecological setting for th current land degradation problem in the West African savanna and thereby indicate possible directions and priorities for future agricultural research.
