Fig. 1: Water scarcity and climate sensitivity of prefectures across China.
From: Prefectures vulnerable to water scarcity are not evenly distributed across China
a Water scarcity index (WS) derived from water demand to water availability (WA) of each prefecture. The WS classes were defined based on the WS values following ref. 10 low (<0.2), medium (0.2–0.4), and high (≥0.4). b Precipitation change (PC) (precipitation reduction) that caused a 25% reduction of WA. A lower PC indicates a higher sensitivity of WA to precipitation change (climate change). Values plotted on the color scales are categorized into three groups following ref. 32 high (≤PC30, dark blue), medium (between PC30 and PC70, blue), and low (≥PC70, shallow blue), in which PCi represents the ith percentile of PC values. Shaded prefectures are ones with positive precipitation changes (negative precipitation reduction) that would still lead to WA reduction. c WS distribution and d PC distribution across districts of China. DB, HB, HD, HN, HZ, XB, and XN are abbreviations of different districts and the full description are shown in Supplementary Fig. 1. Gray-shaded prefectures are excluded from this study.
