![]() With regard to basins, additional kmz-files are available for download, which can be load into a google earth layer. Average monthly and annual factors for basins, countries and world regions are provided through spreadsheets, which differentiate between systems under study referring to unspecified, agricultural and non-agricultural consumptive water uses. 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.Īn overview on all derived factors (evaporation recycling ratios and characterization factors) is presented through the tables below. By aggregating them, we can determine combined net impacts. 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. ![]() 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. 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. ![]() Based on a previously developed dataset 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. ![]() However, the resultant source-receptor relationships between different drainage basins have not yet been considered in 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. Water consumption along value chains of goods and services has increased globally and led to increased attention on water footprinting. ![]()
