More than 25 percent of Africa is desert. The Sahara Desert, the Kalahari Desert and the Namib Desert are the main deserts found in Africa.
The Sahara, the largest hot desert in the world, covers 3.3 million square miles and is located in the northern part of Africa. The Kalahari Desert, located in southern Africa, covers 362,500 square miles. The Namib Desert, the world's oldest desert, is found in the southwestern portion of the continent and covers 100,000 square miles.
Savanna, or grasslands, covers 5 million square miles of Africa, or almost half the continent, and is located mainly in central Africa. While many people associate Africa with rain forests, the majority of those areas have been cut and burned to make way for agriculture and development, and they only cover a small percentage of Africa.
