Full Metadata This EnviroAtlas web service supports research and online mapping activities related to EnviroAtlas (https://www.epa.gov/enviroatlas). The layers in this web service are derived from a dataset produced by Forest Trends' Ecosystem Marketplace containing points and polygons depicting the location of market-based programs and projects addressing ecosystem services protection and their enabling conditions in the United States. This dataset contains polygons and points representing the location of markets and projects primarily targeting watershed-related ecosystem services per Ecosystem Marketplace research. Polygons for projects represent the project footprint (i.e. land area comprising the project site) or area of primary impact. Polygons for markets represent the entire region that shares market infrastructure and rules, or a larger program encompassing many smaller projects. Points represent the centroids of market and project polygons with the exception of national markets, whose points represent administrative headquarters locations. EnviroAtlas allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the conterminous United States as well as detailed metrics for select communities. Additional descriptive information about each attribute in this web service can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).

This map provides a global representation of the dominant economic sector for freshwater withdrawals per major river basins for year 2018. The analysis is based on the national water withdrawal data available in AQUASTAT for year 2018. The dominant sector (SECTOR_DOM) in each river basin is defined as the maximum of the proportion of freshwater water withdrawal for each economic sector respect to the total freshwater withdrawal (TWW) in the basin. Here below the formulas applied: VA_PERC = VA /TWW VS_PERC = VS / TWW VM_PERC = VM/TWW SECTOR_DOM = MAX(VA_PERC, VS_PERC, VM_PERC) Where: VA_PERC = Proportion of the Agriculture freshwater withdrawal over the total freshwater withdrawal (%) VS_PERC = Proportion of the Service freshwater withdrawal over the total freshwater withdrawal (%) VM_PERC = Proportion of Industry freshwater withdrawal over the total freshwater withdrawal (%) TWW = Total freshwater withdrawal (million m3) VA = Freshwater withdrawal for the Agriculture (million m3) VS = Freshwater withdrawal for the Services (million m3) VM = Freshwater withdrawal for the Industry (million m3) **Data publication:** 2022-03-11 **Contact points:** Resource Contact: [Riccardo Biancalani](mailto:riccardo.biancalani@fao.org) Resource Contact: [Michela Marinelli](mailto:michela.marinelli@fao.org) Metadata Contact: [AQUASTAT](mailto:aquastat@fao.org) **Resource constraints:** Creative Commons Attribution-NonCommercial-ShareAlike 3.0 IGO (CC BY-NC- SA 3.0 IGO) **Online resources:** Download: Dominant sector freshwater withdrawal per major river basin (2018)

This dataset is derived from the World Wildlife Fund's (WWF) HydroSHEDS drainage direction layer and a stream network layer. The source of the drainage direction layer was the 15-second Digital Elevation Model (DEM) from NASA's Shuttle Radar Topographic Mission (SRTM). The raster stream network was determined by using the HydroSHEDS flow accumulation grid, with a threshold of about 1000 km² upstream area. The stream network dataset consists of the following information: the origin node of each arc in the network (FROM_NODE), the destination of each arc in the network (TO_NODE), the Strahler stream order of each arc in the network (STRAHLER), numerical code and name of the major basin that the arc falls within (MAJ_BAS and MAJ_NAME); - area of the major basin in square km that the arc falls within (MAJ_AREA); - numerical code and name of the sub-basin that the arc falls within (SUB_BAS and SUB_NAME); - area of the sub-basin in square km that the arc falls within (SUB_AREA); - numerical code of the sub-basin towards which the sub-basin flows that the arc falls within (TO_SUBBAS) (the codes -888 and -999 have been assigned respectively to internal sub-basins and to sub-basins draining into the sea).

The raster stream network was determined by using the HydroSHEDS flow accumulation grid, with a threshold of about 1000 km² upstream area. The stream network dataset consists of the following information: the origin node of each arc in the network (FROM_NODE), the destination of each arc in the network (TO_NODE), the Strahler stream order of each arc in the network (STRAHLER), numerical code and name of the major basin that the arc falls within (MAJ_BAS and MAJ_NAME); - area of the major basin in square km that the arc falls within (MAJ_AREA); - numerical code and name of the sub-basin that the arc falls within (SUB_BAS and SUB_NAME); - area of the sub-basin in square km that the arc falls within (SUB_AREA); - numerical code of the sub-basin towards which the sub-basin flows that the arc falls within (TO_SUBBAS) (the codes -888 and -999 have been assigned respectively to internal sub-basins and to sub-basins draining into the sea). The attributes table now includes a field named "Regime" with tentative classification of perennial ("P") and intermittent ("I") streams. **Data publication:** 2014-03-05 **Supplemental Information:** This dataset is developed as part of a GIS-based information system on water resources for Australia and New Zealand.

**Warning** _Please note that this dataset should not be used as SDG 6.4.2 data._ Level of water stress by major basin calculated on the water consumption (reference year 2018). This map provides a global representation of the level of water stress spatially disaggregated by major river basin based on the freshwater consumption, which is the evapotranspired water in the agricultural sector and the non-returned quota for the industrial and service sectors. The water stress is calculated as the ratio between (a) the amount of freshwater resources consumed in the three economic sectors (Agriculture, Service and Industry) and (b) the total renewable freshwater resources after detracting the amount of water needed to support existing environmental services, also indicated as environmental flows. Statistical data on the return flow are not available in most cases, so a return flow of about 90% was assumed for the services and industrial sectors. For the agricultural sector, the incremental actual ET due to irrigation (estimated using the GlobWat model https://hess.copernicus.org/articles/19/3829/2015/) was used as a proxy. The formula applied is: WSc (%) = [ETinc-irr + (Vs * 0.1) + (Vm * 0.1)] / (TRWR-EF) * 100 Where: - ETinc-irr = incremental ET due to irrigation (from GLobwat) (million m3) - Vs = Water withdrawal for the Service sector (million m3) - Vm = Water withdrawal for the Industry (million m3) - TRWR = Total renewable freshwater resources - EF = Environmental Flow (million m3) Further details on the methodology applied can be found at: https://ucl.scienceopen.com/document/read?vid=18caef6a-0b8f-4e0c-a3e6-807e55d075a2. **Data publication:** 2022-03-11 **Contact points:** Resource Contact: [Riccardo Biancalani](mailto:riccardo.biancalani@fao.org) Resource Contact: [Michela Marinelli](mailto:michela.marinelli@fao.org) Metadata Contact: [AQUASTAT](mailto:aquastat@fao.org) **Data lineage:** Data quality information not available **Resource constraints:** Creative Commons Attribution 4.0 International (CC BY 4.0) **Online resources:** Download: Level of Water Stress by major river basin calculated on the water consumption

Level of water stress (SDG 6.4.2) by major river basin (reference year 2018). This map provides a global representation of the level of water stress spatially disaggregated by major river basin. The indicator 6.4.2 is calculated as the ratio between (a) the amount of total freshwater resources withdrawn in the three economic sectors (Agriculture, Service and Industry) and (b) the total renewable freshwater resources after detracting the amount of water needed to support existing environmental services, also indicated as environmental flows. All the variables are expressed in million m3. The purpose of this indicator is to show the degree to which water resources are being exploited to meet the water demand and it measures the pressure on water resources at basin level. High values of water stress mean more water users are competing for limited water supplies. Low water stress indicates minimal potential impact on resource sustainability and on potential competition among users. Major river basins with an indicator's level lower than 25% have no water stress. Those basins with a water stress greater than 75% have a high or critical water stress. The spatial disaggregation of the indicator by river basin allow the identification of hotspots where actions can be prioritized and reveal that the area affected by a high or critical water stress spans across all continents with the only exception of Oceania. The analysis is based on the national water withdrawal data available in AQUASTAT for year 2018. The total renewable freshwater resources have been assessed using the GloBWat model (https://hess.copernicus.org/articles/19/3829/2015/) and the environmental Flows have been estimated applying the percentages available on the GEFIS portal 2021 (http://eflows.iwmi.org/).
