Identify a community and a population that is found in the kalahari desert?

The Kalahari is home to desert specialties such as meerkat, bat-eared foxes, cape fox and brown hyena. One of the more unexpected Kalahari Desert facts is that all three African big cats can be found here –cheetah, leopard and the famous black-maned Kalahari lions

The Kalahari Desert is inhabited primarily by Bantu speakers and Khoisan-speaking San, with a small number of Europeans
