There's a clear trend in the population density around Africa. You'll notice that most people live in the coastal areas, near big lakes and along the river banks of major rivers like the Nile. The rest of the continent has nothing but barren land.
Thomas Sowell noted that one of the reasons large population centers failed to emerge, in Africa - except for the Nile valley - was the absence of navigable rivers. Most of them are frequently interrupted with nearly unsurmountable cascades, yet transportation of goods and people by water is necessary for large population centers.
