Namibia Kalahari Desert, an arid region that extends into South Africa and Botswana, is one of Namibia's well-known geographical features. The Kalahari, while popularly known as a desert, has a variety of localised environments, including some verdant and technically non-desert areas. The Succulent Karoo is home to over 5,000 species of plants, nearly half of them endemic; approximately 10 percent of the world's succulents are found in the Karoo. The reason behind this high productivity and endemism may be the relatively stable nature of precipitation. Namibia's Coastal Desert is one of the oldest deserts in the world. Its sand dunes, created
Kalahari Craton Archaean-Palaeoproterozoic core of the craton is called the Proto-Kalahari Craton. This core plus accreted Mesoproterozoic crust and dispersed non-African fragments compose the Kalahari Craton. Before the Pan-African Orogeny, the Kalahari Craton was much larger than it is today, but its sutures and therefore its extent are difficult to locate due to later overprinting. The Kaapvaal Craton, Zimbabwe Craton, and Limpopo Belt are made of Archaean terranes and contain crust at least 3.2 and are underlain by a thick () layer of buoyant mantle that is producing garnets and diamonds. During the Palaeoproterozoic the northwest margin of the Archaean core grew
