Water Sustainability and Climate

archived

One of the most urgent challenges facing the world today is to ensure an adequate supply and quality of water in light of both burgeoning human needs and increasing climate variability and change. Despite the importance of water to life on Earth, there are major gaps in our basic understanding of water availability, quality and dynamics, and the impact of both human activity and a changing and variable climate on the water system. The goal of the Water Sustainability and Climate (WSC) solicitation is to enhance the understanding and predict the interactions between the water system and land use changes (including agriculture, managed forest and rangeland systems), the built environment, ecosystem function and services and climate change/variability through place-based research and integrative models. Studies of the water system using models and/or observations at specific sites, singly or in combination, that allow for spatial and temporal extrapolation to other regions, as well as integration across the different processes in that system are encouraged, especially to the extent that they advance the development of theoretical frameworks and predictive understanding. Specific topics of interest include:· Developing theoretical frameworks and models that incorporate the linkages and feedbacks among atmospheric, terrestrial, aquatic, oceanic, biotic and social processes that can be used to predict the potential impact of (1) climate variability and change, (2) land use and (3) human activity (including population change) on water systems on decadal to centennial scales in order to provide a basis for adaptive management of water resources. · Determining the inputs, outputs, and potential changes in water budgets and water quality in response to (1) climate variability and change, (2) land use and (3) human activity (including population change), and the effect of these changes on biogeochemical cycles, water quality, long-term chemical transport and transformation, terrestrial, aquatic and coastal ecosystems, landscape evolution and human settlements and behavior. · Determining how our built water systems and our governance systems can be made more reliable, resilient and sustainable to meet diverse and often conflicting needs, such as optimizing consumption of water for energy generation, industrial and agricultural/forest rangeland production and built environment requirements, reuse for both potable and non-potable needs, ecosystem protection, and flood control and storm water management.This activity enables interagency cooperation on one of the most pressing problems of the millennium--water sustainability -- how it is likely to affect our world, and how we can proactively plan for its consequences. It allows the partner agencies -- National Science Foundation (NSF) and the United States Department of Agriculture National Institute of Food and Agriculture (USDA/NIFA) - to combine resources to identify and fund the most meritorious and highest-impact projects that support their respective missions, while eliminating duplication of effort and fostering collaboration between agencies and the investigators they support.Successful proposals are expected to study water systems in their entirety and to enable a new interdisciplinary paradigm in water research. Proposals that do not broadly integrate across the biological sciences, geosciences, engineering, and social sciences may be returned without review. Projects supported under this solicitation may establish new observational sites or utilize existing observational sites and facilities already supported by NSF (National Science Foundation) or other federal and state agencies (e.g. USGS (US Geological Survey), USEPA (US Environmental Protection Agency), USDA/ARS/FS (US Department of Agriculture/Agricultural Research Station/Forest Service), NOAA (National Oceanic and Atmospheric Administration)).
