This visualization shows Africa's river basins and drainage patterns, with each color representing a different watershed.
The massive purple zone in Central Africa is the Congo River basin, the world's second-largest river system by discharge. The tan area in West Africa shows the Niger River basin, while the thin blue strip on the eastern side represents the Nile, the world's longest river.
These river systems have shaped African civilization for millennia, serving as trade routes, sources of food and water, and natural boundaries. The contrast between the Sahara's sparse networks and the dense tributary systems in equatorial regions shows how climate and topography determine water distribution across the continent.
