Nata River
The Nata River or Manzamnyama River is a natural watercourse in Southern Africa. It is an ephemeral river flowing in Zimbabwe and Botswana. It has a length of 330 km from its source to mouth, 210 km in Zimbabwe and 120 km in Botswana. Its total catchment area is 24,585 km2. The river originates in Sandown (S20.425036˚, E28.180660˚), a small farming town located on the Zimbabwean central watershed 50 km south west of Bulawayo and ends in the Makgadikgadi Pans (S20.348816˚, E26.240166˚) in Botswana. There is no outlet from the salt pans which can be considered as the “dead sea” of the south. The upper reaches of the river are located in a commercial farming area where good environmental and farming practices have resulted in the river experiencing very little siltation/sedimentation. Impressive sedimentation starts occurring about 65 km along the river course marking the beginning of a 90 km stretch in Zimbabwe where the river passes through ...

Botswana
Botswana (, ), officially the Republic of Botswana ( tn, Lefatshe la Botswana, label= Setswana, ), is a landlocked country in Southern Africa. Botswana is topographically flat, with approximately 70 percent of its territory being the Kalahari Desert. It is bordered by South Africa to the south and southeast, Namibia to the west and north, and Zimbabwe to the northeast. It is connected to Zambia across the short Zambezi River border by the Kazungula Bridge. A country of slightly over 2.3 million people, Botswana is one of the most sparsely populated countries in the world. About 11.6 percent of the population lives in the capital and largest city, Gaborone. Formerly one of the world's poorest countries—with a GDP per capita of about US$70 per year in the late 1960s—it has since transformed itself into an upper-middle-income country, with one of the world's fastest-growing economies. Modern-day humans first inhabited the country over 200,000 years ago. The Tswana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zimbabwe
Zimbabwe (), officially the Republic of Zimbabwe, is a landlocked country located in Southeast Africa, between the Zambezi and Limpopo Rivers, bordered by South Africa to the south, Botswana to the south-west, Zambia to the north, and Mozambique to the east. The capital and largest city is Harare. The second largest city is Bulawayo. A country of roughly 15 million people, Zimbabwe has 16 official languages, with English, Shona, and Ndebele the most common. Beginning in the 9th century, during its late Iron Age, the Bantu people (who would become the ethnic Shona) built the city-state of Great Zimbabwe which became one of the major African trade centres by the 11th century, controlling the gold, ivory and copper trades with the Swahili coast, which were connected to Arab and Indian states. By the mid 15th century, the city-state had been abandoned. From there, the Kingdom of Zimbabwe was established, followed by the Rozvi and Mutapa empires. The British Sout ...

Makgadikgadi Pans
The Makgadikgadi Pan (Tswana pronunciation ), 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. Location and description Lying southeast of the Okavango Delta and surrounded by the Kalahari Desert, Makgadikgadi is technically not a single pan, but many pans with sandy desert in between, the largest being the Sua (Sowa), Ntwetwe and Nxai Pans. The largest individual pan is about . In comparison, Salar de Uyuni in Bolivia i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sua Pan
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. The Sua Pan was first described to the European world by David Livingstone, pursuant to his explorations in this region. Significant archaeological recoveries have been made within the Nwetwe Pan, featuring Stone-Age tools from peoples who lived in this area when a large year-round lake occupied the Sua and Nwetwe Pans. The Brines of Sua Pan being one of the largest playa lakes in the world spans approximately 24000 square kilometers. While sodium chloride is the prime constituent, there are many other salts found within this area such as sodium carbonate, sodium bicarbonate, sodium sulfate, and minor amounts of potassium chloride (potash). Currently, Sua Pan is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulawayo
Bulawayo (, ; Ndebele: ''Bulawayo'') is the second largest city in Zimbabwe, and the largest city in the country's Matabeleland region. The city's population is disputed; the 2022 census listed it at 665,940, while the Bulawayo City Council claimed it to be about 1.2 million. Bulawayo covers an area of about in the western part of the country, along the Matsheumhlope River. Along with the capital Harare, Bulawayo is one of two cities in Zimbabwe that is also a province. Bulawayo was founded by a group led by Gundwane Ndiweni around 1840 as the kraal of Mzilikazi, the Ndebele king and was known as Gibixhegu. His son, Lobengula, succeeded him in the 1860s, and changed the name to kobulawayo and ruled from Bulawayo until 1893, when the settlement was captured by British South Africa Company soldiers during the First Matabele War. That year, the first white settlers arrived and rebuilt the town. The town was besieged by Ndebele warriors during the Second Matabele War. Bulaway ...

Wetland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (Anoxic waters, anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or seawater, saltwate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nwetwe Pan
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.C.M.Hogan, 2008 See also * Semowane River References * David Livingstone (1868) ''Missionary Travels and Researches in South Africa: Including a Sketch of Sixteen Years' Residence in the Interior of Africa'', Harper Publishers. * Bryan Robert Davies and Keith F.

Rivers Of Botswana
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, a ...
