Abstract

Extensive areas in Sudano-Sahelian West Africa are experiencing increasing population densities and cultivation pressure, insecure land tenure, low annual rainfall amounts (500-800 mm/yr), and soil infertility, all of which affect local cropping decisions. This detrimental trend has resulted from an expansion of population growth rates since the 1950s and migration from the dryer north to the moister south that began with the droughts of the early 1970s. Before the 1960s, increasing cultivation pressure was dealt with in the Sudano-Sahelian region by expanding cultivation efforts to adjacent uncropped parcels. Though the productivity of each parcel was less than desirable, cultivation demands could still be met by including a greater number of low-yielding parcels. Today, however, such expansion practices are virtually impossible since there are fewer suitable areas left uncropped than ever before. Lands that are less fertile or more sensitive to erosion are still frequently cultivated despite their poor condition because the demand for food in the region is so high.
