Open classification: Africa, desert

Dry inland areas of southern Africa. Also known as "Kalahari Basin", it is the main terrain area in south-central Africa. The total area is about 630,000 square kilometers.

It borders Lake Ngami in the north and the Orange River in the south. It starts at about 26 east longitude in the east and reaches the Atlantic coast in the west. Mainly distributed in Botswana and Namibia, some of which belong to Angola and South Africa.

Geomorphologically, it belongs to a depressed basin on the African platform, with an altitude of 000m- 1 1,000 m, surrounded by mountains and highlands with an altitude of 1 1,500 m. The terrain in the basin is not undulating, and isolated islands and mountains occasionally appear. There are many dry ditches and fine sand on the ground. There are Kalahari dunes in Kalahari Basin, which is the largest dune area in the world.

There are rivers crossing the edge of the basin, whose starting point and ending point are outside the basin: there are Kuanduo River and the upper reaches of Zambezi River in the northeast; There is Cunene R in the northwest and Orange R in the low-lying valley in the south.

There are mainly three basins in the basin: Okowango River system enters the basin from the rainy north, forming a slender swamp belt of 16835 square kilometers. 1849, Livingstone discovered that the Okowango River flows into Ngami L. Although it has been dry for decades, it still exists on the map. Sometimes excess water flows into Kadi depression in Maccati. The smaller watershed in the northwest is called Etoshapan. There is a Molobo-Northob system in the south, which once flowed to the Orange River. There are many muddy areas formed in low-lying areas. These "salt fields" will accumulate rainwater and form a temporary lake until it evaporates and dries up.

Kalahari desert and the central Sahara desert have similar latitudes (only the difference between south latitude and north latitude) and similar climates, which are also influenced by the subtropical high system. The ground is dry all the year round, and the annual precipitation is 125-250 mm.

However, its climate and vegetation are not exactly the same as those of the Sahara desert, because there is a little more precipitation, so it is covered by some vegetation. Climate and vegetation change from southwest to northeast. The west is a desert, where succulents and shrubs grow on sand dunes as high as 100 meters. There is more rainfall in the north and northeast, which is savanna and savanna. In the short rainy season, plants flourish, the ground is covered with fertile grassland, as well as dense shrubs and tall forests. Many antelopes and other tropical animals. But most of the year, the desert is short of water, and many rivers flowing through the desert dry up. Dry land is a real obstacle to exploration in this area.

Bakarahari and Bushmen live in this resource-poor land (rich in diamonds, copper, lead, zinc, nickel, vanadium and other minerals, but rarely exploited at present). Most of them are engaged in animal husbandry and some are engaged in hunting. There is little economic development except in the marginal areas of Kalahari. For example, there is a huge irrigation plan in the Okowango Delta, and the result is nothing. Today, Kalahari is still dry and short of water. When the pioneers of Dambre immigrants tried to cross this place at the end of19th century, they called it "the third place".

Kalahari extends westward into a foggy coastal desert called namib desert, which is very similar to the famous Atacama Desert.
