淡水短缺是一个日益令人关切的问题,因此十分重视用于描述和绘制全世界水资源短缺状况的指标的准确性。我们通过使用蓝色水足迹(地下水和地表水流量的消耗性使用)而不是取水量的估计来改进过去的努力,考虑维持关键生态功能所需的流量,并考虑月度而不是年度值。我们分析了1996-2005年期间的405个流域。在201个流域,有26.7亿居民,一年中至少有一个月严重缺水。水资源日益匮乏的生态和经济后果--正如格兰德河(里奥布拉沃)、印度河和墨累-达令河流域所证明的那样--可能包括旱季的完全干涸、水生生物多样性的大量减少和严重的经济破坏。
Freshwater scarcity is a growing concern, placing considerable importance on the accuracy of indicators used to characterize and map water scarcity worldwide. We improve upon past efforts by using estimates of blue water footprints (consumptive use of ground- and surface water flows) rather than water withdrawals, accounting for the flows needed to sustain critical ecological functions and by considering monthly rather than annual values. We analyzed 405 river basins for the period 1996–2005. In 201 basins with 2.67 billion inhabitants there was severe water scarcity during at least one month of the year. The ecological and economic consequences of increasing degrees of water scarcity – as evidenced by the Rio Grande (Rio Bravo), Indus, and Murray-Darling River Basins – can include complete desiccation during dry seasons, decimation of aquatic biodiversity, and substantial economic disruption.
