指标 6.4.2 - 用水紧张程度:淡水汲取量占可用淡水资源的比例

缺水压力程度:淡水取水量占可用淡水资源的比例是指主要经济部门取用的淡水总量与可再生淡水资源总量在考虑到环境用水需求后的比例。这一指标也称为取水强度,将衡量可持续发展目标具体目标6.4的进展状况。

具体目标 6.4

到 2030 年,所有行业大幅提高用水效率,确保可持续取用和 供应淡水,以解决缺水问题,大幅减少缺水人数。

Indicator 6.4.2: Progress Assessment

影响

该指标将提高有关用水效率和可持续性的知识。 与指标6.4.2一起,它将提供重要信息,以确保水资源能够支持世界生态系统及继续满足子孙后代的需求。

关键信息

全球用水紧张程度尽管自2015年以来略有增加0.2个百分点,2020年仍保持在18.2%的安全水平,但存在很大的区域差异。

在全球层面,2020年的用水紧张程度仍保持在18.2%的安全水平。然而,这掩盖了重大的区域差异,表明自2015年以来增长了1.2%。2020年,用水紧张程度从南亚和中亚的高水平到北非的严重水平不等。北非的情况尤其令人担忧,因为它不仅是唯一一个用水紧张程度达到100%以上临界水平的次区域(这意味着抽取的淡水比可再生淡水资源多)。它还记录到2015年至2020年期间的用水紧张程度猛增15个百分点。
