With a total catchment area of approximately a million square kilometres, the Orange-Senqu River basin is one of the largest in Africa, encompassing the whole of Lesotho and areas of Botswana, Namibia and South Africa.

The basin supports more than 14 million people and the river system plays a vital role in sustaining livelihoods and stimulating economic growth.

Demand for water is predicted to increase with economic growth and development, affirming the need for effective, efficient and sustainable water resources management to maintain these important ecological functions and secure the basin’s resources in the long term.

The governments of the four basin states are well aware of the critical scarcity of water resources in southern Africa and are committed to working together to protect these shared water resources and develop them in a sustainable and equitable way for the benefit of all their people.
