Data to 'The updated and improved method for water scarcity impact assessment in LCA, AWARE2.0'

This dataset includes the AWARE2.0 characterization factors as documented in the article "The updated and improved method for water scarcity impact assessment in LCA, AWARE2.0" (DOI: 10.1111/jiec.70023). When using the dataset in your own work, please cite the article and provide reference to this zenodo repository.

A Python code to reproduce AWARE2.0 on basin resolution is provided on GitHub.

For importing the country-level characterization factors into LCA software, please see the files  for openLCA and SimaPro below. To integrate AWARE2.0 into a brightway workflow, the edges tool (https://github.com/Laboratory-for-Energy-Systems-Analysis/edges) may be useful.

Content

- native resolution (monthly, watershed scale):

• AWARE20_Native_CFs_geospatial.gpkg: Geospatial file containing the AWARE2.0 basins as polygons with associated monthly and annual CFs
• AWARE20_Native_CFs_geospatial.kmz: Version of AWARE20_Native_CFs_geospatial.gpkg for GoogleEarth
• AWARE20_Native_CFs.xlsx: AWARE2.0 CFs on basin level (monthly and annual) and associated water consumption used for weighting
• AWARE20_Intermediate_Variables.xlsx: Intermediate Variables from the calculation of the AWARE2.0 CFs, such as the longterm average natural and actual water availability, the AMDs, the EFRs, etc.
• figures_AWARE_AWARE20_comparison_all_basins.zip: Figures comparing CFs, AMDs, Natural and Actual Availability, EWRs, and EFR coefficients between AWARE and AWARE2.0, for each of the 8149 basins individually. Consult these figures for a visual impression of how and why CFs might have changed between AWARE and AWARE2.0.

- spatiotemporal aggregations:

• AWARE20_Countries_and_Regions.xlsx: AWARE2.0 CFs aggregated according to geography definitions of GLAM and ecoinvent (version 2.5, applicable to ecoinvent 3.10) 
• AWARE20_Subnational_Resolution.xlsx: AWARE2.0 CFs aggregated to subnational resolution, using the GADM dataset version 4.1 (https://gadm.org/old_versions.html)
• AWARE20_Crop_Specific.xlsx: AWARE2.0 CFs aggregated according to geography definitions of ecoinvent (version 2.5, applicable to ecoinvent 3.10), using crop-specific irrigation water consumption for 27 crop classes as spatiotemporal weights. See readme sheet in Excel file for more information.

- files for import into LCA software (based on the implementation for IMPACT World+*):

• AWARE2.0_for_simapro.csv: regionalized CFs for unspecified water use sectors to be imported into SimaPro^†
• AWARE2.0_for_openLCA.zip: regionalized CFs for unspecified water use sectors to be imported into openLCA

* IMPACT World+ version 2.2.1, see https://doi.org/10.5281/zenodo.18892673
^† SimaPro also provides a version of AWARE2.0 by default. However, that implementation is not tested by the authors of this repository.

Changes:

•  v1.0.2:
  • added files for SimaPro and openLCA
•  v1.0.1:
  • addition of crop-specific spatiotemporal aggregations (AWARE20_Crop_Specific.xlsx)
• v1.0.0 (corresponding to published article):
  • update of readme sheets with appropriate references to corresponding article
  • update of reference "Müller Schmied et al. (2024)"
  • added file: AWARE20_Subnational_Resolution.xlsx
•  v0.0.3:
  • use bug-fixed WaterGAP2.2e data from Sept 2023
  • added country and subnational aggregations
  • changed "NoData" to "NotDefined" in the tables
  • added gridcell pHWC to intermediate variables
  • corrected table of water consumption data without post-processing in "Intermediate_Variables"

Note: The the metadata of files are not adjusted to a new repository version number if the file content does not change in that new repository version.

Caveats:

• Spatial CF aggregations for treaties:
  • Due to the creation date of the data set, the BRICS aggregations in AWARE20_Countries_and_Regions.xlsx do not include the states that joined after 2023. In AWARE20_Crop_Specific.xlsx, the 10-member BRICS is labeled BRICS+.
