Descripción
This paper gives an overview of dams in Africa, their main purpose, and future prospects. The inventory includes almost 1 300 large and medium-size dams, 40 percent of which are located in South Africa. The majority of dams has been constructed to facilitate irrigation (52 percent) and to supply water to municipalities (20 percent). Almost 20 percent of dams have multiple purposes, of which irrigation is almost always one of the purposes. Although only 6 percent of dams were built primarily for electricity generation, hydroelectric power accounts for more than 80 percent of total power generation in 18 African countries and for more than 50 percent in 25 countries.
