H12A:
Advances in Ecohydrology of Water-Stressed Environments II


Submit an Abstract to this Session


Session ID#: 62216

Session Description:
Water-stressed environments include drylands and any drought-ridden systems where ecosystem productivity is water limited. Drylands are regions where  precipitation  is  low  relative  to  evapotranspiration. Drylands make up about 40% of the terrestrial land surface and an increasing  number  of  human population  depend  on  them  for  livelihoods  and  survival. Anthropogenic activities (i.e., agriculture and grazing) and global climate changes (i.e., CO2 enrichment, drought and warming) are increasingly affecting the dryland vegetation and water dynamics in many dryland regions worldwide, thereby influencing ecohydrological and geochemical processes, regional climate and the provision of ecosystem services such as livestock grazing, sheltering of the soil surface, and carbon sequestration. These highlight the importance of advancing our understanding of ecohydrological processes in water-stressed environments. 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.
