Limpopo River

The Limpopo River is a massive waterway in southern Africa. It flows from South Africa eastward through Mozambique to the Indian Ocean. This river is the second largest African river to drain into the Indian Ocean. Only the Zambezi River is larger in this regard. The river system covers a very large drainage basin. This basin is the area where water collects and flows into the river. It is a vital part of the geography for several different countries.

The river follows a complex path in a great arc. It first zigzags toward the north. Then it moves in a north-easterly direction. After that, it turns toward the east. Finally, the river flows south-east. The name "Limpopo River" begins at a specific confluence. This is the point where the Marico River and the Crocodile River meet. In some areas, the river acts as a natural border. It separates South Africa from Botswana to the northwest. It also separates South Africa from Zimbabwe to the north.

Geological changes have shaped the river over a long time. The drainage area of the Limpopo has actually decreased. In the Late Pliocene or Pleistocene times, the river was much larger. During those periods, the upper course of the Zambezi River drained into the Limpopo. This changed because of epeirogenic movement. Epeirogenic movement is a type of large-scale uplift of the Earth's surface. This uplift happened north of the present-day Limpopo River. It diverted the waters into the Zambezi River instead.

Many different rivers flow into the Limpopo as tributaries. The Olifants River, also called the Elephant River, is the main tributary. It contributes about 1,233 million cubic meters of water every year. Other major tributaries include the Shashe, Mzingwane, and Luvuvhu Rivers. The Notwane River is another major tributary. It rises on the edge of the Kalahari Desert in Botswana. The river's flow can change based on the season. Rainfall is often seasonal and can be unreliable. In dry years, the upper parts might only flow for 40 days or less.

Human history in this region goes back millions of years. Fossils of Australopithecus were found in the Makapans Valley near Mokopane. These fossils date back 3.5 million years. Much later, the European explorer Vasco da Gama arrived in 1498. He was likely the first European to sight the river. He anchored his ships near the mouth of the river. In the late 1800s, explorers mapped more of the water. St Vincent Whitshed Erskine explored the lower course in 1868–69. Captain J F Elton traveled the middle course in 1870.

The Limpopo basin is home to approximately 14 million people. The environment changes as you move along the river. The upper parts near the Kalahari Desert are arid and dry. Further down, the river drains the Waterberg Massif. This area is a biome of semi-deciduous forest. The fertile lowlands support more people than the drier areas. There is also significant mining activity in the basin. There are about 1,900 functioning mines in the area. Additionally, there are about 1,700 abandoned mines.

Wildlife is a major part of the Limpopo ecosystem. You can find a high concentration of hippopotamus between the Mokolo and Mogalakwena Rivers. Nile crocodiles also live here. In 2013, about 15,000 crocodiles were accidentally released from a farm into the river. Even Zambezi sharks live in these waters. These sharks can tolerate fresh water and travel far upriver. The river can also be dangerous due to weather. In February 2000, a cyclone caused catastrophic flooding in Mozambique.

The river's appearance is often described as slow and silty. Rudyard Kipling famously described it as a "great grey-green, greasy Limpopo River."
