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, and parts of Namibia and South Africa.
The Okavango Delta in Botswana is a swampy inland delta formed where the Okavango River reaches a tectonic trough at an altitude of 930–1,000 m in the central part of the endorheic basin of the Kalahari. All the water reaching the delta is ultimately evaporated and transpired and does not flow into any sea or ocean. Each year, about 11 cubic kilometres (2.6 cu mi) of water spreads over the 6,000–15,000 km2 (2,300–5,800 sq mi) area. Some flood waters drain into Lake Ngami. The area was once part of Lake Makgadikgadi, an ancient lake that had mostly dried up by the early Holocene.
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 Tsodilo Hills are a UNESCO World Heritage Site (WHS), consisting of rock art, rock shelters, depressions, and caves in southern Africa. It gained its WHS listing in 2001 because of its unique religious and spiritual significance to local peoples, as well as its unique record of human settlement over many millennia. UNESCO estimates there are over 4500 rock paintings at the site. The site consists of a few main hills known as the Child Hill, Female Hill, and Male Hill.
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 covering most of Botswana and Namibia, as well as 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 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 different 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.
Ngarrabullgan, officially named Mount Mulligan by the State, is a large tabletop mountain located 100 kilometres west of Cairns in the north of Queensland (Australia).
Azykh Cave, also referred to as Azokh Cave is a six-cave complex in Azerbaijan, known as a habitation site of prehistoric humans. It is situated near the village of Azykh in the Khojavend District.
Botswana's principal tourist attractions are its game reserves, with hunting and photographic safaris available. Other attractions include the Okavango Delta region, which during the rainy season is a maze of waterways, islands, and lakes. The tourism industry also helped to diversify Botswana's economy from traditional sources such as diamonds and beef and created 23,000 jobs in 2005.
Makapansgat is an archaeological location within the Makapansgat and Zwartkrans Valleys, northeast of Mokopane in Limpopo province, South Africa. It is an important palaeontological site, with the local limeworks containing Australopithecus-bearing deposits dating to between 3.0 and 2.6 million years BP. The whole Makapan Valley has been declared a South African Heritage Site. Makapansgat belongs to the Cradle of Humankind.
Gwihabaite is a rare ammonium potassium nitrate mineral (NH4,K)(NO3). It is orthorhombic in form, colorless with a vitreous luster. It has a Mohs hardness of 5 and a specific gravity of 1.77. It is deliquescent and water-soluble. The mineral is also known as nitrammite. It was first described in 1996 for an occurrence in Gcwihaba Caves (Drotsky's Cavern, type locality), Maun, North-West District, Botswana. The spelling of the name was simplified, omitting the "c", which represents the "click" sound used by the San people. It occurs as incrustations and efflorescences on cave surfaces formed by bacterial action on bat guano.
Cueva Fell is a natural cave and archaeological site in southern Patagonia. Cueva Fell is in proximity to the Pali Aike Crater, another significant archaeological site. Cueva Fell combined with the nearby Pali Aike site have been submitted to UNESCO as a possible World Heritage Site.
The Con Moong cave is located in the Cúc Phương National Park, just south of Mọ village, in the Thanh Hóa Province, northern Vietnam. The Department of Culture has issued a certificate that declares Con Moong prehistoric site and its surroundings as National Relics and is managed by the Cúc Phương National Park administration, along with a refuge for rare animals. Among these locations, the archaeological site of Con Moong cave is of central importance for the study of the Mesolithic Hoabinhian culture. In April and May 1976, Vietnamese archaeologists excavated the site.
Risovača Cave, is situated at the very entrance of the town of Aranđelovac in central Serbia around 17 m (56 ft) above the Kubršnica river valley. It is one of the most important archaeological sites of the Palaeolithic in Serbia besides the Gradac Cave near Kragujevac. Its discovery confirmed the assumed existence of the Paleolithic culture south of the Sava-Danube line and provided new information on the life of prehistoric humans in Europe.
The Kalahari Acacia-Baikiaea woodlands are an ecoregion located in Botswana, northern Namibia, South Africa and Zimbabwe.
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.
The Hadži-Prodan's Cave is an archaeological site of the Paleolithic period and a national natural monument, located in the village Raščići around 7 km (4.3 mi) from Ivanjica in western central Serbia. The rather narrow and high entrance with at an altitude of 630 m (2,070 ft) above sea level sits about 40 m (130 ft) above the Rašćanska river valley bed and is oriented towards the south. The 345 m (1,132 ft) long cave was formed during the Late Cretaceous in "thick-bedded to massive" Senonian limestone. Prehistoric pottery shards and Pleistocene faunal fossils had already been collected by Zoran Vučićević from Ivanjica. Animal fossils especially Cave bear and Iron Age artifact discoveries during an unrelated areal survey were reportedly made at the cave entrance and in the main cavern. The site is named in honor of Hadži-Prodan, a 19th century Serbian revolutionary.
