Data Use - Transboundary River Basins: Status and Trends
United Nations Environment Programme—April 2016
For a report assessing the world’s 286 transboundary river basins, SEDAC data were used in the calculation of three indicators: economic dependence on water resources, societal wellbeing levels, and the risk of climate-related hazards.
