Kalahari Desert Book

The Kalahari Desert is a large arid to semi-arid sandy area in Southern Africa extending 900,000 square kilometres, covering much of Botswana and parts of Namibia and South Africa, as semi-desert, with huge tracts of excellent grazing after good rains. The Kalahari Desert is the southern part of Africa, and the geography is a portion of desert and a plateau. The Kalahari supports some animals and plants because most of it is not true desert. There are small amounts of rainfall and the summer temperature is very high. It usually receives 3-7.5 inches of rain per year. The surrounding Kalahari Basin covers over 2,500,000 square kilometres extending farther into Botswana, Namibia and South Africa, and encroaching into parts of Angola, Zambia and Zimbabwe. The only permanent river, the Okavango, flows into a delta in the northwest, forming marshes that are rich in wildlife. Ancient dry riverbeds-called omuramba-traverse the Central Northern reaches of the Kalahari and provide standing pools of water during the rainy season.
