A map shows Africa's ecosystems. It shows that most of North Africa, a small region along Africa's east coast, and a small region along southern Africa's west coast are desert. It shows that beneath the desert regions of North Africa, a band of Sahel runs from the Africa's east coast to its west coast. It shows that small regions of Sahel are also found along Africa's northern coast. It shows that rain forest is found in central Africa, and in small regions along Africa's west coast and on the neighboring island off its east coast. It shows that savanna encircles the central rain forest region, covering the majority of central and southern Africa.

The two areas that made it possible for people in these ecosystems to use the trans-Saharan trade route are the desert regions of North Africa and the Sahel region.
