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.

The Zambezi (also spelled Zambeze and Zambesi) 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 km 2 (540,000 sq mi), [4][5] slightly less than half of the Nile 's.

Zambezi River, river draining a large portion of south-central Africa. Together with its tributaries, it forms the fourth largest river basin of the continent. The river flows eastward for about 2,200 miles (3,540 kilometres) from its source on the Central African Plateau to empty into the Indian Ocean .

Zambezi River Basin The Zambezi River Basin covers six African countries, spanning 1.3 million square kilometers and supporting a population of over 55 million. It serves as a vital resource for livelihoods, agriculture, and transport while boasting rich biodiversity and the famous Victoria Falls, a UNESCO World Heritage Site.

ZAMWIS (the Zambezi Water Resources Information System) contains Time Series as well as Knowledge Products for the Zambezi River Basin. In addition, Zambezi Basin Flow Forecasting is now accessible online.

The Zambezi basin is the fourth-largest river basin of Africa, after the Congo/Zaire, Nile and Niger basins. Its total area represents about 4.5% of the area of the continent and spreads over eight countries (Map 8 and Table 38).

4 days ago · The Upper Zambezi sub-basin has the highest proportion of wetland coverage, with 94.61 % (19,184 km2) in Angola (specifically the Kameia and Luena wetlands), promoting river health. This study highlights the recognition Angola deserves for its critical role in hosting the source and primary aquifer of the Zambezi River.

The approved CIF funding, totalling $60.35 million, will support two major projects across the basin.

The Zambezi is one of the major river basins in Africa, well endowed with water and land resources, as well as other natural resources. Hydropower and irrigation are considered important means of economic development in the basin.
