Among the most urgent challenges facing the world today is ensuring the adequate supply and quality of water, scientists say, especially in light of burgeoning human needs and climate variability and change.
Despite water's importance to life on Earth, major gaps exist in our understanding of water availability, quality and dynamics, and the impacts of a changing climate and human activity on Earth's water system.
To better understand how our planet's water cycle works, the National Science Foundation (NSF) has awarded 17 grants through its Water Sustainability and Climate (WSC) solicitation.
The goal of these projects is to understand and predict the interactions of Earth's water system with climate change, land use, the built environment, and ecosystem function and services.
"We need to determine how our built water systems and our governance systems can be made more reliable, resilient, and sustainable," says Tim Killeen, NSF assistant director for Geosciences.
"They must meet diverse and often conflicting needs," says Killeen, "such as minimizing consumption of water for energy generation, industrial and agricultural production, and built environment requirements."
The awards are for studies of the water system using observations at specific sites, in combination with models that allow for spatial and temporal extrapolation to other regions, as well as integration across different Earth processes.
"The results will advance our understanding of Earth's water resources," says Killeen, "and with it, our predictive capability not only for the availability of water, but for the future of life on our planet."
