The Cuando River (or Kwando in the non-colonial spelling) is a river in south-central Africa flowing through Angola and Namibia's Caprivi Strip and into the Linyanti Swamp on the northern border of Botswana. [3] Below the swamp, the river is called the Linyanti River and, farther east, the Chobe River, [4] before it flows into the Zambezi River.
The Cuando rises in the central plateau of Angola on the slopes of Mount Tembo, [5] thence flowing southeast along the Zambian border. Along this reach it flows in a maze of channels in a swampy corridor 5–10 km wide (map 1: the border with Zambia is the eastern bank of this floodplain, not the river channel). As with all rivers in south-central Africa its flow varies enormously between the rainy season when it floods and may be several kilometres wide, and the dry season when it may disappear into marshes.
The Cuando continues in its marshy channel across the neck of the Caprivi Strip of Namibia (map, 2) and then forms the border between Namibia and Botswana as it continues southeast. Some 10,014 years ago, the Cuando merged with the Okavango River and they flowed south to Lake Makgadikgadi (which is a seasonal wetland in current times [6] ), but the land in that area was uplifted. As a consequence the Cuando now meets slightly higher ground (map, 4) and breaks up into many channels and swamps (called the Linyanti Swamp) dotted with alluvial islands, nearly disappearing into the Kalahari sands like the Okavango (map, 5). But instead it has diverted east and has been captured by the Zambezi. The flow turns sharply east, still forming the border with Botswana. In the dry season there are few open channels through the swamps and marshes. Beginning at this point it is known as the Linyanti (map, 6), and after it flows through a seasonal lake, Lake Liambesi (map, 7), it is called the Chobe (map, 8). The river then flows into the Zambezi just above the former Kazungula Ferry (map, 9), now replaced by the Kazungula Bridge.
In years when the Okavango experiences a good flood some of the water escapes east along the normally dry channel of the Magwekwana River (also known as Selinda Spillway) into the Linyanti Swamp, thus entering the Zambezi basin. The Selinda Spillway and the Boteti River are the only outlets of the Okavango basin.
On the north side of the Chobe River are the Caprivi Swamps, on the edge of which is the ruined capital of the Kololo people who conquered Barotseland in the 19th century.
So much of the water of the Cuando, Linyanti and Chobe is lost to evaporation in the various swamps that its contribution to the flow of the Zambezi is very small except in occasional years when it floods excessively.
The perennial river bifurcation of Selinda Spillway (or Magweggana River), on the Cuando River, connects the Kalahari Basin to the Zambezi Basin. [7]
The Cuando system is noted for its wildlife and for most of its length the land either side is protected as game reserves or wildlife management areas. Some of these suffered poaching during wars and conflict in Namibia and Angola, but with peace restored in those countries they have the chance of returning to their former state.
The national parks through which it passes or on which it borders are:
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 Zambezi is the fourth-longest river in Africa, the longest east-flowing river in Africa and the largest flowing into the Indian Ocean from Africa. Its drainage basin covers 1,390,000 km2 (540,000 sq mi), slightly less than half of the Nile's. The 2,574-kilometre-long (1,599 mi) river rises in Zambia and flows through eastern Angola, along the north-eastern border of Namibia and the northern border of Botswana, then along the border between Zambia and Zimbabwe to Mozambique, where it crosses the country to empty into the Indian Ocean.
The Zambezi Region is one of the 14 regions of Namibia. It is located in the north-eastern part of the country. It is largely concurrent with the major Zambezi River after which it was named. The region has eight constituencies and its capital is the town of Katima Mulilo. The self-governed village Bukalo is also situated in this region. The Zambezi Region had a population of 90,596 in 2011. As of 2020, it had 47,884 registered voters.
The Caprivi Strip, also known simply as Caprivi, is a geographic salient protruding from the northeastern corner of Namibia. It is bordered by Botswana to the south and Angola and Zambia to the north. Namibia, Botswana and Zambia meet at a single point at the eastern tip of the Strip, which also comes within 150 m (490 ft) of Zimbabwe thus nearly forming a quadripoint. Botswana and Zambia share a 150-metre (490 ft) border at the crossing of Kazungula. The territory was acquired by then-German South West Africa in order to provide access to the Zambezi River and consequently a route to the east coast of the continent and German East Africa. The route was later found not to be navigable because of the location of the Victoria Falls, one of the world's largest waterfalls, about 65 kilometres east of the Caprivi Strip.
The Okavango River, also known as the Cubango River, is a river in southwest Africa. 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.
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.
Kazungula is a small border town in Zambia, lying on the north bank of the Zambezi River about 70 kilometres (45 mi) west of Livingstone on the M10 Road.
Kasane is a town in Botswana, close to Africa's 'Four Corners', where four countries almost meet: Botswana, Namibia, Zambia and Zimbabwe. It is at the far north-eastern corner of Botswana where it serves as the administrative center of the Chobe District. The population of Kasane was 9,244 in 2011 census.
Sioma Ngwezi National Park is a 5,000-square-kilometre park in the south west corner of Zambia. It is undeveloped and rarely visited, lacking roads and being off the usual tourist tracks, but this may change in the future.
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.
Bwabwata National Park is a protected area in northeastern Namibia that was established in 2007 and covers 6,274 km2 (2,422 sq mi). It was created by merging Caprivi Game Park and Mahango Game Reserve. It is situated in the Zambezi and Kavango East regions, extending along the Caprivi Strip. It is bounded by the Okavango River to the west and the Kwando River to the east. Angola lies to the north and Botswana to the south.
Mudumu is a National Park in Caprivi Region in north-eastern Namibia. The park was established in 1990. It covers an area of 737 square kilometres (285 sq mi). The Kwando River forms the western border with Botswana. Various communal area conservancies and community forests surround Mudumu National Park.
Nkasa Rupara National Park, also Nkasa Lupala National Park, formerly Mamili National Park, is a national park in Namibia. It is centered on the Nkasa and Rupara islands on the Kwando/Linyanti River in the south-western corner of East Caprivi. Botswana lies to the west, south and east, and Sangwali village to the north. It is Namibia's largest formally protected wetland area. It is one of Namibia’s protected areas that benefits local communities surrounding parks. The unfenced park forms a trans-boundary link for wildlife migration between Angola, Botswana, Namibia and Zambia. Nkasa Rupara is part of the Kavango Zambezi Transfrontier Conservation Area.
The M10 Road is a road in Zambia. It goes from Livingstone, through Sesheke and Senanga, to Mongu. The road is approximately 508 kilometres and follows the Zambezi River for its entire length.
The Zambezi basin is an African drainage basin, whose main flow is the Zambezi River, being the fourth largest basin on the continent, in addition to being the most important basin in southern Africa. It covers approximately 1,390,000 km², crossing regions with high population density, sometimes in areas of low density, such as the Kavango–Zambezi Transfrontier Conservation Area. The Zambezi Watercourse Commission (ZAMCOM) has been in existence since 2004 with the aim of strengthening cooperation in sharing its resources concerned. Another supranational initiative for watershed management is Zambezi River System Action Plan (ZACPLAN).
