[1] Water-limited environments occupy about half of the Earth's land surface and contain
some of the fastest growing population centers in the world. Scarcity or variable
distributions of water and nutrients make these environments highly sensitive to change.
Given the importance of water-limited environments and the impacts of increasing
demands on water supplies and other natural resources, this paper highlights important
societal problems and scientific challenges germane to these environments and presents a
vision on how to accelerate progress. We argue that improvements in our fundamental
understanding of the links between hydrological, biogeochemical, and ecological
