Global patterns and trends in ecological water scarcity

Caption

(a) Spatial distribution of basins experiencing EWS in the 2000s. (b) Temporal trends in EWS severity (1850s–2000s). (c) Transitions between EWS categories (annual/seasonal/no EWS); numbers indicate basin counts. (d) Decadal changes in EWS, showing means (colored lines) and interquartile ranges (shading) across GHM –GCM ensembles. (e) Percentage of basins experiencing EWS across 150 years, with individual model results (crosses) and ensemble means (bars). (f) Intensification of EWS levels between historical periods, displayed as in panel (e).
