semidesert region flanking the middle course of the Sénégal River and lying north of the Ferlo region, in northern Senegal. The banks of the Sénégal River are well-watered and fertile in the Fouta region, yet the thin, sandy clay of the region's interior plains is infertile and porous. Water is found near the surface in only a few shallow depressions. This region was historically the site of several Fulani states. (See Fulani empire. (Fulani empire)) Many of the Fulani (Fulbe) and Mauri (Maure) people who inhabit the region have switched from nomadic to sedentary lifestyles. Irrigation, long practiced in Fouta, was enhanced by Sénégal River irrigation projects in the late 20th century.
