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.
