This Call to Action event will make progress on the Connecting the World for Transboundary Groundwater Resilience (TGR) UN Water Action Commitment. Presentations on case studies, data analyses, network analyses, and simulation modeling methods will provide a basis for group discussion. Participants are encouraged to share best practices and priorities from their local regions and fields of study. This event will focus on data, systems, networks, and community-based approaches to foster Transboundary Groundwater Resilience. We welcome you to join us!
