Innovative Science and Influential Policy Dialogues for Water Security in the Arid Americas
This project proposes to assess current and future water security in the arid Americas through a comparative lens on river basin human-environment dynamics. With partners from institutions in Chile, Argentina, Brazil, and Mexico, and through iterative engagement with regional stakeholders, we will project future water quality and quantity scenarios in six principal river basins (Maipo River Basin, Chile; Mendoza River Basin, Argentina; Capibaribe River Basin, Brazil; Sonora River Basin, Mexico; Santa Cruz River Basin, USA; and Piura River Basin, Peru), all of which experience urban-rural competition for water. We will also conduct this research for five analogue basins, which have previously experienced or will experience conditions of change analogous to those in the principal basins. The analogue basins are the Elqui River Basin, Chile; Tunuyán River Basin, Argentina; Pajeú River Basin, Brazil; Yaqui River Basin, Mexico; San Bernardino River Basin, USA; and Lambayeque River Basin, Peru. The goal of this research is to strengthen decision-making under uncertainty in these arid regions.
