Groundwater is essential for millions living along the arid US-Mexico border, yet persistent droughts, increasing demand, and population growth continue to strain these critical resources. This WRRC Water Webinar will explore a multicriteria approach to prioritize transboundary aquifers in the Arizona–Sonora border region, leveraging publicly available data to assess which shared aquifers would benefit most from binational studies. The findings, which were recently published, highlight key regional disparities in groundwater needs and provide a replicable framework for improving cross-border aquifer assessments.
