Water represents a portfolio of assets, including surface water, groundwater, and soil water (“green” water). Recycled water (“gray” water) is not considered a water asset as it is derived from water extracted from the environment and circulates within the economy. Ocean water is not considered an asset needing valuation as it is essentially limitless and industrial processes are needed to make it suitable for most uses (for example, desalination for drinking water and pumping for cooling). The report identified three approaches for estimating values consistent with the value of the other natural capital assets in CWON: (1) asset-by-asset, (2) use-by-use, and (3) service-by-service.en-USCC BY-NC 3.0 IGOWATER ALLOCATION AND WATER ECONOMICSWATER SUPPLY AND SANITATIONWATER SECURITY AND INTEGRATED RESOURCE MANAGEMENTCLEAN WATER AND SANITATIONSDG 6ReportWorld Bank10.1596/42356
