Water limited environments include naturally occurring drylands and any ecosystem experiencing droughts. Drylands cover more than 40% of the terrestrial land surface and home to at least 2 billion people. In drylands, water availability, ecosystem productivity, surface energy balance and biogeochemical cycles are tightly coupled. Both climatic (e.g., increase in aridity, recurring droughts) and anthropogenic factors (e.g., land use change, energy development) are increasingly affecting the dryland water dynamics. It is thus important to understand the consequences of hydrological changes on ecosystem functions in drylands to predict long-term changes in food production, to understand the impacts of changing climate, and to evaluate management options. We welcome submissions focusing on the ecohydrological processes/feedbacks in drylands and their quantification using novel methodologies, and their implications on a broad range of issues including ecosystem change, land use change, water resources, desertification, and food-energy-water nexus.
