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 by accretion and had formed a Proto-Kalahari Craton by 1.75 Ga. During the period 1.4–1.0 Ga subduction occurred along the northwest margin followed by continental collisions along the eastern and southern margins. By this time enough Mesoproterozoic crust had accreted to transform the Kalahari Craton. At 1.11 Ga, during the assembly of the supercontinent Rodinia, the Kalahari Craton was affected by the Umkondo-Borg Large Igneous Province. At 1.15–.98 Ga the Kalahari Craton collided with the eastern margin of Laurentia. Kalahari Craton The Kalahari Craton is a craton, an old and stable part of the continental lithosphere, that occupies large portions
