Kalahari Desert in the context of "Khoe languages"

Botswana, officially the Republic of Botswana, is a landlocked country in Southern Africa. Botswana is topographically flat, with approximately 70% of its territory being a part of the Kalahari Desert. It is bordered by South Africa to the south and southeast, Namibia to the west and north, Zambia to the north, and Zimbabwe to the northeast. With a population of slightly over 2.4 million people and a comparable land area to France, Botswana is one of the most sparsely populated countries in the world. It is essentially the nation-state of the Tswana people, who constitute nearly 80% of the population.

The Tswana ethnic group are descended mainly from Bantu-speaking peoples who migrated into southern Africa, including modern Botswana, in several waves before AD 600. In 1885, the British colonised the area and declared a protectorate named Bechuanaland. As part of the decolonisation of Africa, Bechuanaland became an independent Commonwealth republic under its current name on 30 September 1966. Since then, it has been a parliamentary republic with a consistent record of uninterrupted democratic elections, though dominated by the Botswana Democratic Party until 2024. As of 2024, Botswana is the least corrupt country in mainland Africa according to the Corruption Perceptions Index published by Transparency International.

The Kalahari Basin, also known as the Kalahari Depression, Okavango Basin or the Makgadikgadi Basin, is an endorheic basin and large lowland area covering approximately 725,293 km (280,037 sq mi) — mostly within Botswana and Namibia, but also parts of Angola, South Africa, Zambia, and Zimbabwe. The outstanding physical feature in the basin, and occupying the centre, is the large Kalahari Desert.

The Namib (/ˈnɑːmɪb/, NAH-mib; Portuguese: Namibe) is a coastal desert in Southern Africa. According to the broadest definition, the Namib stretches for more than 2,000 kilometres (1,200 mi) along the Atlantic coasts of Angola, Namibia, and northwest South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River in Western Cape, South Africa. The Namib's northernmost portion, which extends 450 kilometres (280 mi) from the Angola-Namibia border, is known as Moçâmedes Desert, while its southern portion approaches the neighboring Kalahari Desert. From the Atlantic coast eastward, the Namib gradually ascends in elevation, reaching up to 200 kilometres (120 mi) inland to the foot of the Great Escarpment. Annual precipitation ranges from 2 millimetres (0.079 in) in the aridest regions to 200 millimetres (7.9 in) at the escarpment, making the Namib the only true desert in southern Africa. Having endured arid or semi-arid conditions for roughly 55–80 million years, the Namib may be the oldest desert in the world and contains some of the world's driest regions, with only western South America's Atacama Desert to challenge it for age and aridity benchmarks. Most of Namibia's share of the Namib Desert is protected under the environmental protection included in the constitution of the country.

The desert geology consists of sand seas near the coast, while gravel plains and scattered mountain outcrops occur further inland. The sand dunes, some of which are 300 metres (980 ft) high and span 32 kilometres (20 mi) long, are the second-largest in the world after the Badain Jaran Desert dunes in China. Temperatures along the coast are stable and generally range between 9–20 °C (48–68 °F) annually, while temperatures further inland are variable—summer daytime temperatures can exceed 45 °C (113 °F) while nights can be freezing. Fogs that originate offshore from the collision of the cold Benguela Current and warm air from the Hadley cell create a fog belt that frequently envelops parts of the desert. Coastal regions can experience more than 180 days of thick fog a year. While this has proved a major hazard to ships—more than a thousand wrecks litter the Skeleton Coast—it is a vital source of moisture for desert life.

The springbok or springbuck (Antidorcas marsupialis) is an antelope found mainly in south and southwest Africa. The sole living member of the genus Antidorcas, this bovid was first described by the German zoologist Eberhard August Wilhelm von Zimmermann in 1780. Three subspecies are identified. A slender, long-legged antelope, the springbok reaches 71 to 86 cm (28 to 34 in) at the shoulder and weighs between 27 and 42 kg (60 and 93 lb). Both sexes have a pair of black, 35-to-50 cm (14-to-20 in) long horns that curve backwards. The springbok is characterised by a white face, a dark stripe running from the eyes to the mouth, a light brown coat marked by a reddish-brown stripe that runs from the upper foreleg to the buttocks across the flanks like the Thomson's gazelle, and a white rump flap.

Active mainly at dawn and dusk, springbok form harems (mixed-sex herds). In earlier times, springbok of the Kalahari Desert and Karoo migrated in large numbers across the countryside, a practice known as trekbokking. A feature, peculiar but not unique, to the springbok is pronking, in which the springbok performs multiple leaps into the air, up to 2 m (6.6 ft) above the ground, in a stiff-legged posture, with the back bowed and the white flap lifted. Primarily a browser, the springbok feeds on shrubs and succulents; this antelope can live without drinking water for years, meeting its requirements through eating succulent vegetation. Breeding takes place year-round, and peaks in the rainy season, when forage is most abundant. A single calf is born after a five- to six-month-long pregnancy; weaning occurs at nearly six months of age, and the calf leaves its mother a few months later.

The geology of Namibia encompasses rocks of Paleoproterozoic, Mesoproterozoic and Neoproterozoic and Paleozoic to Cenozoic age. About 46% of the countryʼs surface are bedrock exposure, while the remainder is covered by the young overburden sediments of the Kalahari and Namib deserts.

The country is famous for its mineral deposits of Tsumeb, as well as many geological sites of interest, from paleontological, geomorphological and volcanic character. Due to the exposure of the formations in a desert climate and the former German colony, the geology of Namibia is relatively well studied compared to the more tropical less exposed northern neighbors.

Omaheke (the Otjiherero word for sandveld) is one of the fourteen regions of Namibia, the least populous region. Its capital is Gobabis. It lies in eastern Namibia on the border with Botswana and is the western extension of the Kalahari Desert. The self-governed villages of Otjinene, Leonardville, and Witvlei are situated in the region. As of 2020, Omaheke had 48,594 registered voters.

The pula is the currency of Botswana. It has the ISO 4217 code BWP and is subdivided into 100 thebe. Pula literally means "rain" in Setswana, because rain is very scarce in Botswana—home to much of the Kalahari Desert— playing a major role in rites of traditional Tswana belief; therefore valuable and the word extends its meaning as "blessing" or "fortune". The word also serves as the national motto of the country.

A sub-unit of the currency is known as thebe, or "shield", and represents defence. The names were picked with the help of the public.
