Course and Watershed of the Limpopo River
The 'Limpopo River' rises in the interior of
Africa, and flows generally eastwards towards the
Indian Ocean. It is around 1,600 kilometers long (or 1,770 km according to another source). The Limpopo is the second largest
river in Africa that drains to the east after
Zambezi River. The Limpopo river flows in a great arc, first zig-zagging northeast and north, then turning east and finally southeast.
Then it serves as a border for about 640 kilometres, separating
South Africa on the southeast bank from
Botswana in the northwest and
Zimbabwe on the north. There are several
rapids as the river falls off Southern Africa's interior
escarpment.
The main tributary is the
Olifants/Letaba river (Elephant River). The port town of
Xai-xai,
Mozambique is on the river near the mouth. Below the Olifants, the river is permanently
navigable to the sea, though a
sandbar prevent large ships' access except at high tide.
The waters of the Limpopo are indeed sluggish and silty.
Rainfall is seasonal and unreliable. In dry years, the upper parts of the river flow for 40 days or less. The upper part of the
drainage basin is arid, in the
Kalahari desert, but becomes ever less arid further down the river. The next reaches drain the
Waterberg massif, a
biome of semi-
deciduous forest and low density human population.
[1] The lower reaches are fertile and heavily populated. Floods after the rainy season are an occasional problem in the lower reaches, most notably the catastrophic
floods in February
2000, which was caused by heavy rainfall and a cyclone.
At the north-eastern corner of South Africa the river touches the greatest conservation area.
14 Million people live in the Limpopo river basin, an area around 413,000 km². Water demand exceeds supply. Most of the people living in the Limpopo river basin are poor, and starvation and malnutrition are not uncommon during
drought or crop failure.
Vasco da Gama was the first European to sight the river, when one of his expeditions anchored off the mouth in
1498. However, there has been human habitation in the region since time immemorial - sites in the Makapans Valley near
Mokopane contain
Australopithecus fossils from 3.5 million years ago.

The Limpopo was immortalized in the short story "The Elephant's Child" by British author
Rudyard Kipling, in the ''
Just So Stories,'' where it is described as "the great grey-green, greasy Limpopo River, all set about with
fever-trees," where the "Bi-Coloured Python Rock-Snake" dwells.
