Which of these countries contains the largest portion of the Kalahari Desert?

The Kalahari Desert is found principally in Botswana on the African continent. The Kalahari Desert is a large semi-arid sandy savanna in southern Africa extending 900,000 square kilometers, covering much of Botswana, parts of Namibia, and regions of South Africa. It is a semi-desert, with tracts of excellent grazing after good rains. The Kalahari supports more animals and plants than a true desert. The driest areas usually receive 110–200 mm. (4.3–7.9 in) of rain per year, and the wettest just a little over 500 mm. (20 in).

In former times there were wild animals including elephants to giraffes, and also predators such as lions and cheetahs. Now the riverbeds are mostly grazing spots, although leopards and cheetahs can still be found. The area is now heavily grazed and cattle fences restrict the movement of wildlife.

The San people have lived in the Kalahari for 20,000 years as hunter-gatherers. They hunt wild game with bows and poison arrows and gather edible plants.
