This Brown International Advanced Research Institute will focus on changes in the supply of and demand for water in the 21st century, due both to changes in regional climate and to human population growth and development patterns. Major themes will include predicted changes in regional hydrologic cycles; resilience of existing social, economic, civil, ecological, and agricultural systems to likely changes; the potential of global and local institutions to increase the resilience of these systems; and what can be learned from one region to inform effective design of policies and water management structures in other regions. Throughout the Institute, participants will focus on developing interdisciplinary research through communication and joint development of projects.
