全球范围内，货物和服务价值链沿着的水消耗量增加，导致人们更加关注水足迹问题。大多数全球水消耗是由蒸发（E），这是通过大气水分传输的桥梁连接到地球上的其他地区。然而，由此产生的不同流域之间的源受体关系尚未被考虑在水足迹。基于先前开发的关于陆地蒸发命运的数据集，我们的目标是通过首次使用关于水足迹中蒸发再循环的全面信息来缩小这一差距。通过考虑流域内部蒸发再循环（BIER;世界2%的流域>5%）和流域外部蒸发再循环（BEER;世界37%的流域>50%），我们能够使用三种类型的水资源清单（流域内部，流域外部和跨界清单），这意味着水足迹的不同评估视角。利用最近开发的影响评估方法，我们制作了表征模型，用于评估蓝色和绿色水蒸发对所有评估视角的蓝色水可用性的影响。结果表明，在起源盆地的蒸发的负面影响抵消（和部分过度补偿）的积极影响，再降水在接收盆地。通过汇总这些影响，可以确定综合净影响。虽然我们认为这些抵消结果不应该被用作一个独立的评估，水足迹社区应该考虑在未来的标准和指导方针大气水分循环。
Water consumption along value chains of goods and services has increased globally and led to increased attention on water footprinting. Most global water consumption is accounted for by evaporation (E), which is connected via bridges of atmospheric moisture transport to other regions on Earth. However, the resultant source–receptor relationships between different drainage basins have not yet been considered in water footprinting. Based on a previously developed data set on the fate of land evaporation, we aim to close this gap by using comprehensive information on evaporation recycling in water footprinting for the first time. By considering both basin internal evaporation recycling (BIER; >5% in 2% of the world’s basins) and basin external evaporation recycling (BEER; >50% in 37% of the world’s basins), we were able to use three types of water inventories (basin internal, basin external, and transboundary inventories), which imply different evaluation perspectives in water footprinting. Drawing on recently developed impact assessment methods, we produced characterization models for assessing the impacts of blue and green water evaporation on blue water availability for all evaluation perspectives. The results show that the negative effects of evaporation in the originating basins are counteracted (and partly overcompensated) by the positive effects of reprecipitation in receiving basins. By aggregating them, combined net impacts can be determined. While we argue that these offset results should not be used as a standalone evaluation, the water footprint community should consider atmospheric moisture recycling in future standards and guidelines.
