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.</mods:abstract><mods:classification authority="lcc">Others</mods:classification><mods:originInfo><mods:dateIssued encoding="iso8061">1990</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>Elsevier</mods:publisher></mods:originInfo><mods:genre>Article</mods:genre></mods:mods>
