Luangwa River ago, there was no way out and the Luangwa Rift filled with a Rift Valley Lake called the Madumabisa Lake, which rivalled Lake Malawi in size. The water of the lake overflowed in a river to the south-west, towards what is now the Kalahari, where it combined with the Okavango, Upper Zambezi, Cuando and Kafue rivers, emptying into the Limpopo River and flowing to the Indian Ocean. Several geological events combined to produce the current river systems. Faulting produced another graben just to the south of the Luangwa Rift, and running east-west: the Zambezi Rift Valley and the Chicoa Trough.
Water in Africa traverse multiple borders. This particular constraint can also be converted into an opportunity if the potential for trans-boundary cooperation is harnessed in the development of the area’s water resources. A multi-sectoral analysis of the Zambezi River, for example, shows that riparian cooperation could lead to a 23% increase in firm energy production without any additional investments. A number of institutional and legal frameworks for transboundary cooperation exist, such as the Zambezi River Authority, the Southern African Development Community (SADC) Protocol, Volta River Authority and the Nile Basin Commission. However, additional efforts are required to further develop political will, as well
