The Zambezi River Basin is the fourth largest basin of Africa with an area of 1.32 million km2 shared by eight countries (Angola, Botswana, Malawi, Mozambique, Namibia, Tanzania, Zambia and Zimbabwe) and populated by almost 40 million inhabitants. In 2004 an agreement among the eight riparian states was signed to create the Zambezi Watercourse Commission (ZAMCOM) with the purpose of enhancing the cooperation over the shared water resource of the Zambezi River Basin to increase agricultural yields, hydropower production and economic opportunities.
