Africa is being given a unique opportunity to conserve its tremendous diversity of freshwater species – a critical resource for many of Africa’s poorest people. African countries can now decide to use their water resources sustainably, and avoid paying millions of dollars, as is the case in Europe, to rectify poorly planned wetland development.
Decision makers across Africa are now able to benefit from an online interactive map, released by IUCN, for each of the 7,079 river and lake sub-catchments across mainland Africa that reveals information on the distribution, conservation and ecological needs of 4,989 freshwater species, of which 21% are already threatened. This tool and the accompanying IUCN Red List of Threatened Species™ report ‘The Diversity of Life in African Freshwaters: Underwater, Under Threat’ provide vital information to help plan development in ways that minimize or avoid impacts to freshwater species.
“This is a real milestone in the history of African freshwater biodiversity – nothing as good, or like it, is out there at this point in time,” says Paul Skelton, Managing Director, South African Institute for Aquatic Biodiversity. “The information on freshwater fishes has already proved its worth in a number of conservation planning projects in South Africa, including work on the legal protection of threatened species and the establishment of a national framework of freshwater protected areas.”
According to the report the number of threatened freshwater species in Africa will increase dramatically if development of water resources is not planned sustainably. Major threats include loss or degradation of habitat to agriculture, and impacts of new infrastructure such as dams for irrigation and hydropower.
“Provision of species information at the sub-catchment scale for all of Africa represents a major step forward and will greatly assist water resource management throughout Africa,” says Ali Kaka, IUCN Regional Director for Eastern and Southern Africa.
