The State of Global Water Resources report series offers a comprehensive and consistent overview of water resources worldwide, highlighting the influence of climatic, environmental and societal changes on the hydrological variables. The 2022 edition of the State of Global Water Resources Report marks the second report in the annual series, following the successful pilot edition for 2021 launched in 2022. The first edition of the report was well received and led to increased participation from WMO Member States and Territories, National Hydrological and Meteorological Services, and other organizations, including members of the global hydrological modelling community, in the preparation of the 2022 report. Its impact was further amplified by substantial engagement from external stakeholders and the general public, as well as wide media coverage.
