Future water constraints on United States lithium mining under climate change

This repository contains the supporting information and underlying data used in the publication: "Future water constraints on United States lithium mining under climate change" by Trost et al. (2026) The Supplementary Information Excel file contains information and data on mine sites, water use of mines and from literature, and annual production data and estimates. This repository includes python code and data used to conduct the analysis. In order to run the code and source data properly, file directories will need to be updated to the directories where the data and code has been downloaded to. Population_Projections includes code and data to support Figure 8. Temp_Precip_Changes includes code and data to support Figures 4 and 5. Uncertainty Analysis includes code and data to support Figures 6 and 7. Supplemental Data 1 includes location data to support Figure 2 and direct water use estimates of lithium mining from literature to support Figure 1. Water supply data are from Caldwell et al. (2019) and the Water Supply Stress Index Model (WaSSI). Please contact the authors for full access to their data. Water demand data for non-mining sectors are from Warziniack et al. (2022). Please contact the authors for full access to their data.
