United Nations Environment Programme (UNEP) has led global efforts, through UN-Water and its partners, for countries to report on the status of implementation of IWRM, agreed at the World Summit on Sustainable Development in Johannesburg in 2002, and reinforced as SDG Target 6.5 on integrated water resources management and transboundary cooperation.
UNEP is the global custodian of SDG indicator 6.5.1 on Integrated Water Resources Management, supporting countries to develop and implement national IWRM processes.
The UNEP-DHI Centre on Water and Environment conducts extensive work on IWRM worldwide, including supporting countries to monitor, plan and implement IWRM through the Sustainable Development Goals. The IWRM Data Portal helps countries track progress towards Target 6.5.
