The Okavango 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 miles). It begins in Angola, where it is known as the Cubango River. Further south it forms part of the border between Angola and Namibia, and then flows into Botswana, draining into the Moremi Wildlife Reserve.
Before it enters Botswana, the river drops 4 meters, across the full 1.2km-width of the river, in a series of rapids known as Popa Falls, visible when the river is low, as during the dry season.
Unusually, the Okavango does not have an outlet in the sea. Instead, it empties into a swamp in the Kalahari Desert, known as the Okavango Delta. Part of the river's flow fills Lake Ngami. World famous for its remarkable wildlife, the Okavango area contains the Moremi Wildlife Reserve (Botswana).
Botswana, however uses the Okavango Delta for both tourism income and a water source. The department of water affairs in Botswana argues that 97% of the water in the river is lost through evaporation, so the country cannot afford to lose any extra water.
Namibia, however, argues that it will only divert half a percent of the river's flow, and that it is entitled to any water that flows through its country. The dispute seemed to have four clear alternatives; Alternative water collection sources, Negotiation, United Nations legal intervention and War. To bypass these options, in 1994 Namibia and Botswana signed the Okavango River Basin Commission (OKACOM), agreeing to the fair usage of the water in the Okavango river which they share.
