Dams
Geo-referenced dams database AQUASTAT gathers detailed information about dams in each country during country update processes. AQUASTAT’s data was an important input into the Global Reservoirs and Dams (GRanD) database, especially for African dams. The work on this database was coordinated by the Global Water System Project, in partnership with several organizations. An article has been published in 2011 in the Journal Frontiers in Ecology and the Environment.
