State of Global Water Resources

This report is the World Meteorological Association’s annual stocktake on how global freshwater availability is being affected by our changing climate. It provides an overview of trends and major events related to river discharge, reservoirs, groundwater levels, high-impact hydrological events (such as floods and droughts), and highlights hotspots for changes in freshwater storage, including the crucial role and vulnerability of snow and ice. These insights will be most useful to strategic planning and risks teams as well as others involved in horizon scanning or scenario analysis.
