长期以来，人们习惯于将全球水短缺称为一场"危机"，总认为这只是暂时的阵痛，终将迎来复苏。然 而，联合国大学20日发布的一份最新报告打破了这一幻想。 这份名为《全球水资源破产：后危机时代水资源匮乏现状》的报告指出，人们熟悉的"水资源紧 张"和"水资源危机"等术语，已无法反映当今许多地区的严峻现实。相反，后危机时代的特点是自然水 资源资本遭遇不可逆转的损失，系统已无法恢复到历史基线水平。这不仅是"流量"的匮乏，更是"存 量"的枯竭。 正如联合国大学水、环境与健康研究所所长卡维·马达尼所言："对世界大部分地区来说，'常态'已成过 去。"这不再是短期波动的阵痛，而是一个必须诚实面对的系统性失败，倒逼我们从传统的"危机应 对"彻底转向"破产管理"。 水系统陷入"资不抵债" 这份报告指出，世界已经进入"全球水资源破产"时代。 如何理解"全球水资源破产"?报告将其定义为"资不抵债"与"不可逆性"的交织。在这种状态下，长期的 取水量与污染负荷已双双突破可再生补给的红线。 当水系统陷入破产，人类的"饭碗"首当其冲。报告数据显示，全球约70%的淡水抽取用于农业，而地下 水则支撑了全球约50%的生活用水和40%的灌溉需求。 目前， ...
