The region is at risk of desertification. Over-farming, over-grazing, and over-population of marginal lands and natural soil erosion have caused serious desertification of the region.

Major dust storms are a frequent occurrence, as well. During November 2004, a number of major dust storms hit the Chad, Nigeria, and northern Cameroon, originating in the Bodélé Depression. This is a common area for dust storms (occurring, on average, 100 days every year).

iN August 2008, heavy dust storms passed over the eastern plains of Somalia and the northeast of a still drought-hit Kenya. In March 2010, a major sandstorm hit Mauritania, Senegal, the Gambia, Guinea Bissau, Guinea, and inland Sierra Leone. Another struck in southern Algeria, inland Mauritania, Mali, and northern Côte d’Ivoire at the same time.
