Figure 16.3 Population ratio under high water stress. Future projections of the population ratio under high water stress are depicted: (a) water scarcity index, where water withdrawal (W)/renewable freshwater (Q) exceeds 0.4; (b) water-crowding indicator, based on an assumption that less than 1000 m3 water availability (Q) per capita per year is water-scarce. The horizontal axis shows global-averaged surface air temperature increase in the future scenarios.

(a) W/Q > 0.4 (b) Q/capita < 1000 m3/capita/yr
