The growing mismatch between freshwater resources and demand calls for better understanding of the water cycle, and its links to human activities. SAGE research focuses on the physical basis of hydrologic cycles, and also on the dynamic relationships between water and agriculture, climate and health, including socio-economic factors. SAGE researchers continually develop, refine and use computer models to investigate topics such as phosphorus pollution in local watersheds, trade-offs of water and carbon in biofuel production, and large basin-scale water management.
