Geography of South Africa - The Central Plateau

The Central Plateau

The Central Plateau has a large range of landscape. It is drained by two major rivers, the Orange and the Limpopo, and is made up of 10 smaller geographic regions. The altitude varies from 600 to 2,500 m and the rainfall varies from 200 to 1200 mm annually. It is ringed in the east, south and west by the Great Escarpment. In general the Great Escarpment slowly loses altitude into the northwestern areas of the Central Plateau. In the west it is very dry, merging with the Kalahari in the northwest. In the central areas the arid scrubland gives way to dry grasslands which become better watered further to the east. These grasslands extend northeastward until they reach the Witwatersrand and Magaliesberg, which are the main watershed between the Orange and Limpopo Rivers. The Witwatersrand and Magaliesberg also form part of an area of low mountain ranges surrounding a basin called the Bushveld. To the north of that the semi-arid savanna loses altitude towards the Limpopo River valley. The regions are outlined in more detail below.
