Advances in ecohydrology of arid environments
Session ID#: 162104
Session Description:
Water-stressed environments include naturally occurring drylands and any ecosystems experiencing droughts. Drylands cover more than 40% of the terrestrial land surface and home to at least 2 billion people. Water availability, ecosystem productivity, surface energy balance and biogeochemical cycles are tightly coupled in water-stressed environments. Both climatic (e.g., increase in aridity, recurring droughts) and anthropogenic factors (e.g., land use change, energy development) are increasingly affecting the ecohydrological processes in water-stressed environments. It is thus important to understand the consequences of hydrological changes on ecosystem functions 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 water-stressed environments 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.
