Last week, WRRC Director Sharon B. Megdal and Associate Director Jamie McEvoy traveled to Hermosillo, the capital of the Mexican state of Sonora, to participate in a Transboundary Aquifer Assessment Program (TAAP) workshop. Director Megdal described the workshop as “participatory, positive, and productive.” In coordination with representatives from the International Boundary and Water Commission (IBWC/CILA - US and Mexican sections), collaborators from the Department of Geology at the University of Sonora (Unison) helped organize the workshop, which was held on the Unison campus September 10–11. Other TAAP partners in attendance included representatives from the US Geological Survey (USGS), the National and State Commissions of Water in Mexico (CONAGUA and CEA, respectively), and the Mexican Geological Service (SGM). Director Megdal had the opportunity to share remarks on the importance of engagement and outreach and discuss the factors that contribute to successful transboundary outcomes. As described in her recent Reflections, this includes “eating with your partners,” illustrated in the photo of our dinner with TAAP partners!
