West Africa's water tower

Guinea occupies the hinge between coastal West Africa and the continental interior. Its most important geographic feature is the Fouta Djallon highlands, a sandstone plateau rising over 1,500 meters in the center of the country and the source of the Niger, Senegal, and Gambia rivers. Being the region's hydrological origin point carries quiet strategic weight: what happens to Guinea's forests and watersheds affects water availability across a vast swath of the continent.

More on Fouta Djallon

Rivers rise here and flow in every direction, reaching the Atlantic through Senegal, The Gambia, Guinea-Bissau, and Sierra Leone, and running inland to feed the Niger basin. Deforestation on the plateau threatens downstream water systems across the region.
