Zambezi River Basin - Atlas of the changing EnvironmentZambezi River Basin - Atlas of the changing Environment
The Zambezi River Basin Atlas of the Changing Environment is a basin collaborative initiative with the objective of providing scientific evidence about changes that are taking place in the natural resources and the environment. The Atlas, with climate change as its running theme, is for use by policy makers and other stakeholders, and the general public, to generate action towards climate resilience through adaptation and mitigation of the impacts of climate change.

Zambezi River Basin vegetation Zambezi River Basin vegetation
Land cover and land use have great impacts on water resources, as they affect how precipitation translates into runoff, infiltration, evaporation, and the quality of the water (Hirji et al. 2002). Almost 75 per cent of the land area in the basin is forest and bush. Cropped land with mostly rain-fed agriculture covers 13 per cent of the land area, and grassland covers about 8 per cent of the land area.

Zambezi River Basin average temperature Zambezi River Basin average temperature
The temperature across the river basin varies according to elevation and, to a much lesser extent, latitude. Mean monthly temperatures for the coldest month, July, vary from below 13°C for higher elevation areas in the south of the basin to 23°C for low elevation areas in the delta in Mozambique. The coolest area is the south-eastern part of the basin, part of which is in Zambia and the other part is in Zimbabwe. Ground frost occurs locally in s...

Zambezi River Basin Zambezi River Basin
The Zambezi River Basin is located between 8–20° S latitude and 16.5–36° E longitude in southern Africa (Chenje 2000). It drains an area of almost 1.4 million square kilometres, stretching across 8 of the 15 member states of the Southern African Development Community (SADC).

Zambezi River Basin average rainfall Zambezi River Basin average rainfall
Average annual rainfall across the river basin varies from 500mm in the extreme south and southwest part of the basin to more than 1 400 mm in the Upper Zambezi and Kabompo sub-basins, in the north-eastern shores of Lake Malawi/Nyasa/Niassa in Tanzania, and in the southern border area between Malawi and Mozambique (Chenje 2000). Rainfall is greatest in the north, with an extensive area receiving over 1 000 mm, and declines towards the south, ...

Zambezi River Basin hydropower facilities Zambezi River Basin hydropower facilities
The hydropower potential of the Zambezi River Basin is estimated at 20 000 megawatts (MW)of which about 5 000 MW has been developed (Tumbare 2004). More than half of this potential is in Mozambique, about one-quarter in Zambia and one-sixth in Zimbabwe (SADC and ZRA 2007). The Cahora Bassa, Kariba and Kafue Gorge dams provide the bulk of the basin’s hydropower, generating 2 075 MW, 1 470 MW and 990 MW of electricity, respectively (World Bank ...

Zambezi River Basin share by country Zambezi River Basin share by country
The Zambezi River Basin has 13 sub-basins, most of which are transboundary. The largest portion of the basin lies in Zambia, with smaller segments in Angola, Zimbabwe, Mozambique and Malawi in that order. Tanzania, Botswana and Namibia have less than three per cent of the basin each.

Africa major river basins Africa major river basins
There are 63 transboundary river basins in Africa, covering 64 per cent of the continent’s land area (UNEP 2010). The Zambezi basin is the fourth largest in Africa after the Congo, Nile and Niger River Basins (Mukosa and Mwiinga 2008).
