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

 

用水紧张程度不均衡,威胁全球发展。

截至2023年,全球用水压力相对稳定在17.6%。然而,从区域层面仔细观察,情况更加令人担忧,西亚和北非正面临着严重的缺水问题。自2015年以来,这些区域的用水压力飙升了6%,突出表明亟需采取有针对性的干预措施来应对这些挑战。

经济部门在影响用水紧张程度方面也发挥着关键作用。经济部门在塑造水资源压力水平方面也发挥着关键作用。农业仍然是淡水的主要用户,占2023年总取水量的81%,其次是服务业(14%)和工业(5%)。

在许多国家,农业在确保粮食安全和推动经济发展方面发挥着至关重要的作用,但农业也面临着日益严峻的用水紧张挑战,既造成危机,也深受其害,是极易受到危机影响的部门。
