Kalahari Desert

The Kalahari Desert is a large arid to semi-arid sandy area in southern Africa extending to some 900,000 km² and covering much of Botswana, and parts of Namibia and South Africa. The surrounding Kalahari Basin covers over 2.5 million km² extending farther into Botswana, Namibia and South Africa, and encroaching into parts of Angola, Zambia and Zimbabwe. The only permanent river, the Okavango, flows into a delta in the northwest, forming marshes that are rich in wildlife. Ancient dry riverbeds—called omuramba—traverse the Central Northern reaches of the Kalahari and provide standing pools of water during the rainy season. Previously havens for wild animals from elephant to giraffe, and for predators such as lion and cheetah, the riverbeds are now mostly grazing spots, though leopard or cheetah can still be found.

Climate

Derived from the Tswana word Kgalagadi, meaning the great thirst, the Kalahari has vast areas covered by red-brown sands without any permanent surface water. Drainage is by dry valleys, seasonally inundated pans, and the large salt pans of the Makgadikgadi Pan in Botswana and Etosha Pan in Namibia. However, the Kalahari is not a true desert. Parts of the Kalahari receive over 250 mm of erratic rainfall annually and are quite well vegetated; it is only truly arid in the south-west (under 175 mm of rain annually) making the Kalahari a fossil desert. Summer temperatures in the Kalahari range from 20 to 40 °C. In winter, the Kalahari has a dry, cold climate with frosts at night. The low winter temperature can average below 0 °C.

Game reserves

The Kalahari has a number of game reserves - the Central Kalahari Game Reserve (CKGR, the world's second largest protected area), Khutse Game Reserve and the Kgalagadi Transfrontier Park. Animals that live in the region include brown hyenas, lions, meerkats, several species of antelope (including the oryx or gemsbok), and many species of bird and reptile. Vegetation in the Kalahari consists mainly of grasses and acacias but there are over 400 identified plant species present (including the wild watermelon or tsamma melon).

Ancestral land

The area is the ancestral land of the Bushmen (San) peoples. There are many distinct tribes, and they have no collective name for themselves. The names San and Basarwa are sometimes used, but the people themselves dislike these names (San is a Khoikhoi word meaning outsider, and Basarwa a Herero word meaning person who has nothing) and prefer the name "Bushman". The name bushmen was given to them by early settlers who may have named them for the fact they live in the bush or it might have been given because of there use of aromatic spices collected from various bushes. They are thought to have been the first human inhabitants of Southern Africa; there is evidence that they have been living there continuously as nomadic hunter-gatherers for at least 22,000 years. The Bushmen of the Kalahari desert were first brought to the western world's attention in the 1950s when author Laurens van der Post published his most famous work The Lost World of the Kalahari, which was also turned in to a BBC TV series. This and other later works about the Kalahari prompted the creation of the Central Kalahari Game Reserve in 1961 in order to preserve the Bushmen and their homeland.

Kalahari minerals

There are large coal, copper, nickel and uranium deposits in the region. One of the largest diamond mines in the world is located at Orapa in the Makgadikgadi, North-Eastern Kalahari.

Resettlements

In 2002, the Botswana government forced all the Bushmen from their lands within the borders of that country and "resettled" them in fixed encampments. The government has given several different justifications for their action: that it was for purposes of nature conservation; that it was too expensive to continue to supply the Bushmen with water (the water table had been lowered by farming and other development); that it was "to enable them to share in the wealth of the country"; that it was for their own good to become settled and "civilized".

Diamond mining

The overseas campaign group Survival International say the real reason for the re-settlement is to free up the land for diamond mining, especially in the area of Orapa, the diamond capital of the country. But the Botswana Centre for Human Rights, Ditshwanelo, disputes this, claiming that the government is being altruistic, but misguided. Nonetheless, the London Daily Telegraph of October 29, 2005 reported that the government had begun another wave of forced removals.
