The Kalahari Desert is a large semi-arid sandy savannah in Southern Africa extending for 900,000 square kilometres (350,000 sq mi), covering much of Botswana, and 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".
