Advancing Sustainability of U.S.-Mexico Transboundary Drylands

The drylands region shared by the United States and Mexico currently faces multiple sustainability challenges at the intersection of the human and natural systems. Warming and drying conditions threaten surface water and groundwater availability, disrupt land- and marine-based livelihood systems, and challenge the sustainability of human settlements. These biophysical challenges are exacerbated by a highly mobile and dynamic population, volatile economic and policy conditions, increased exposure to extreme events, and urbanization on marginal, vulnerable lands. The U.S. National Academies of Sciences, Engineering, and Medicine collaborated with the Mexican Academy of Sciences, Academy of Engineering, and the National Academy of Medicine to plan a 2-day binational workshop, Advancing Sustainability of U.S.-Mexico Transboundary Drylands. The workshop goals were to highlight the challenges facing the region, assess the scientific and technical capacity that each nation can bring to bear in addressing these challenges, and identify new opportunities for binational research collaboration and coordinated management approaches in the advancement of sustainability science and development. This publication summarizes the presentations and discussions from the workshop.
