The Orange-Senqu River Basin (ORB) Study provides details of the data, sources, methodology, and maps for 14 water-related indicators across the Orange-Senqu River Basin in Southern Africa. The ORB Study is primarily designed for research organizations for analysis and research purposes.
Prior to the creation of the global Aqueduct Water Risk Atlas, indicators were developed and tested in a number of river basins worldwide. The results of the Orange-Senqu River Basin Study helped inform and shape the global Aqueduct Water Risk Framework. The Orange-Senqu River Basin study contains 14 indicators of water quantity, water variability, water quality, public awareness of water issues, access to water, and ecosystem vulnerability.
