The Kalahari Desert is a large semi-arid sandy savanna in Southern Africa extending for 900,000 square kilometres, covering much of Botswana, as well as parts of Namibia and South Africa. It is not to be confused with the Angolan, Namibian, and South African Namib coastal desert, whose name is of Khoekhoegowab origin and means "vast place".
