H12B:
Advances in Ecohydrology of Water-Stressed Environments I


Session ID#: 10605

Session Description:
Water-stressed environments include naturally occurring drylands and any ecosystem under drought. Drylands cover 40% of the terrestrial land surface and support at least 2 billion people. Water is fundamental to sustain ecosystem functions in water-stressed environments, where a tight coupling exists between water availability, ecosystem productivity, surface energy balance, and biogeochemical cycles. Both physical (e.g., CO2, temperature) and anthropogenic factors (e.g. agriculture, energy development) are increasingly affecting the dryland water dynamics. We welcome submissions focusing on the ecohydrological processes/feedbacks in water-stressed environments and their implications on a broad range of issues including ecosystem change, land use change, water resources, desertification, and food-energy-water nexus.
