Botswana is a landlocked country located in Southern Africa, north of South Africa. Botswana occupies an area of 581,730 square kilometres (224,610 sq mi), of which 566,730 km2 (218,820 sq mi) are land. Botswana has land boundaries of combined length 4,347.15 kilometres (2,701.19 mi), of which the constituent boundaries are shared with Namibia, for 1,544 km (959 mi); South Africa 1,969 km (1,223 mi); Zimbabwe, 834 km (518 mi) and Zambia, 0.15 km (0.093 mi). Much of the population of Botswana is concentrated in the eastern part of the country.
The Kalahari Desert is a large semi-arid sandy savanna in Southern Africa extending for 900,000 square kilometres (350,000 sq mi), covering much of Botswana, as well as parts of Namibia and South Africa.
The Okavango River, is a river in southwest Africa. It is known by this name in Botswana, and as Cubango in Angola, and Kavango in Namibia. It is the fourth-longest river system in southern Africa, running southeastward for 1,600 km (1,000 mi). It begins at an elevation of 1,300 metres (4,300 ft) in the sandy highlands of Angola. Farther south, it forms part of the border between Angola and Namibia, and then flows into Botswana. The Okavango does not have an outlet to the sea. Instead, it discharges into the Okavango Delta or Okavango Alluvial Fan, in an endorheic basin in the Kalahari Desert. The Cuito River is a major tributary.
Lake Makgadikgadi was a paleolake that existed in what is now the Kalahari Desert in Botswana from 2,000,000 years BP to 10,000 years BP. It may have once covered an area of from 80,000 to 275,000 km2 and was 30 m deep. The Okavango, Upper Zambezi, and Cuando rivers once all emptied into the lake. Its remains are seen in the Makgadikgadi salt pans, one of the largest salt pans in the world.
Chobe National Park is Botswana's first national park, and also the most biologically diverse. Located in the north of the country, it is Botswana's third largest park, after Central Kalahari Game Reserve and Gemsbok National Park.
The Boteti River is a natural watercourse in Botswana. It derives flow from the core Okavango Delta through the Thamalakane River in Maun.
The North-East District is one of the administrative districts of Botswana. Its capital is Francistown. In 2011, North-East had a population of 60,264 people. The district is predominantly occupied by Kalanga-speaking people, the BaKalanga. The district is administered by a district administration and district council, which are responsible for local administration.
The North-West District or Ngamiland is one of the first-level administrative subdivisions of Botswana. For census and administrative purposes Ngamiland is subdivided into Ngamiland East, Ngamiland West and Ngamiland Delta (Okavango). It is governed by a District Commissioner, appointed by the national government, and the elected North-West District Council. The administrative centre is Maun.
The Makgadikgadi Pan, a salt pan situated in the middle of the dry savanna of north-eastern Botswana, is one of the largest salt flats in the world. The pan is all that remains of the formerly enormous Lake Makgadikgadi, which once covered an area larger than Switzerland, but dried up tens of thousands of years ago. Recent studies of human mitochondrial DNA suggest that modern Homo sapiens first began to evolve in this region some 200,000 years ago, when it was a vast, exceptionally fertile area of lakes, rivers, marshes, woodlands and grasslands especially favorable for habitation by evolving hominins and other mammals.
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 km2 - 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.
Adansonia digitata, the African baobab, is the most widespread tree species of the genus Adansonia, the baobabs, and is native to the African continent and the southern Arabian Peninsula. These are long-lived pachycauls; radiocarbon dating has shown some individuals to be over 2,000 years old. They are typically found in dry, hot savannas of sub-Saharan Africa, where they dominate the landscape and reveal the presence of a watercourse from afar. They have traditionally been valued as sources of food, water, health remedies or places of shelter and are a key food source for many animals. They are steeped in legend and superstition. In recent years, many of the largest, oldest trees have died, for unknown reasons. Common names for the baobab include monkey-bread tree, upside-down tree, and cream of tartar tree.
The wildlife of Botswana refers to the flora and fauna of this country. Botswana is around 90% covered in savanna, varying from shrub savanna in the southwest in the dry areas to tree savanna consisting of trees and grass in the wetter areas. Even under the hot conditions of the Kalahari Desert, many species survive; in fact the country has more than 2500 species of plants and 650 species of trees. Vegetation and its wild fruits are also extremely important to rural populations living in the desert and are the principal source of food, fuel and medicine for many inhabitants.
The Ntwetwe Pan is a large salt pan within the Makgadikgadi region of Botswana. The Ntwetwe is one of three large pans within the Makgadikgadi, the other two being Nxai Pan and Sua Pan. Ntwetwe Pan is now a seasonal lake with filling occurring in the rainy season. Ntwetwe was first described to the European world by David Livingstone, pursuant to his explorations in this region. Significant archaeological recoveries have occurred within the Nwetwe Pan, including Stone Age tools from people who lived in this area, in an earlier time of prehistory when a large year round lake occupied the Nwetwe Pan area within the Makgadikgadi.
The Sua Pan or Sowa Pan is a large natural topographic depression within the Makgadikgadi region of Botswana. It is located near the village of Sowa, whose name means salt in the language of the San. The Sua salt pan is one of three large pans within the Makgadikgadi, the other two being Nxai Pan and Nwetwe Pan.
Nxai Pan is a large salt pan topographic depression which is part of the larger Makgadikgadi Pans in northeastern Botswana. It lies on the old Pandamatenga Trail, which until the 1960s was used for overland cattle drives. The area is speckled with umbrella acacias and is said to resemble the Serengeti in Tanzania. The Nxai Pan was added to the National Park System to augment the Makgadikgadi Pans National Park, thus providing an enlarged contiguous area of natural protection.
The Kalahari Acacia-Baikiaea woodlands are an ecoregion located in Botswana, northern Namibia, South Africa and Zimbabwe.
Kavango–Zambezi Transfrontier Conservation Area is the second-largest nature and landscape conservation area in the world, spanning the international borders of five countries in Southern Africa. It includes a major part of the Upper Zambezi River and Okavango basins and Delta, the Caprivi Strip of Namibia, the southeastern part of Angola, southwestern Zambia, the northern wildlands of Botswana and western Zimbabwe. The centre of this area is at the confluence of the Zambezi and Chobe Rivers where the borders of Botswana, Namibia, Zambia and Zimbabwe meet. It incorporates a number of notable national parks and nature sites, including Chobe National Park, Hwange National Park, and the Victoria Falls. The region is home to a population of approximately 250,000 animals, including the largest population of African Elephants in the world.
Gweta is a small village in Botswana. It lies about 205 kilometres (127 mi) away from Maun and about 100 kilometres (62 mi) from Nata.
The Nata Bird Sanctuary, the only protected reserve in the northeastern periphery of Sowa Pan in Botswana, is a community-managed project, with assistance from the Nata Conservation Committee and national and international organizations. Founded in 1988, it opened for operations in 1993; it encompasses an area of 230 square kilometres (89 sq mi), with the objective of conservation of wildlife. The community project is managed by a Trust titled the "Kalahari Conservation Society", which has members drawn from the four villages of Nata, Sepako, Maposa and Manxotae in the vicinity of the sanctuary.
