Extended Data Fig. 3: Population exposure to water scarcity in the Latin America & Caribbean region under uncertain climate and socio-economic change.
From: Current and future global water scarcity intensifies when accounting for surface water quality
a) Number of people exposed to water scarcity from 2005–2100, based on indicators considering water quantity only (WS) and including water quality (WSq). Thick lines and thin lines display the annual average and monthly average exposure to water scarcity, respectively, while shaded areas represent uncertainty arising from variations in GCM simulations as ±1 s.d. b) Percentage of the population exposed to seasonal (that is at least one month per year) and year-round (>9 months per year) water scarcity from 2005–2100, as indicated by WS and WSq. Lines display the mean average exposure per year averaged over the five GCMs considered, while shaded areas represent uncertainty arising from variations in GCM simulations as ±1 s.d. c) Percentage of the population exposed to water scarcity in each month, as indicated by WS and WSq. Boxplots are made based on monthly exposure to water scarcity across all GCMs for a historical reference period (2005–2020) and under three global change scenarios at the end of the century (2081–2100).
