B21M:
Past, Present, and Future of Water-Limited Ecosystems: Local Trends to Global Impacts III Posters


Submit an Abstract to this Session


Session ID#: 47317

Session Description:
Water-limited ecosystems, encompassing arid, semi-arid and sub-humid regions (also referred to as drylands), cover ~40% of the earth surface, host major centers of plant diversity, support over third of the global human population - mainly in the developing countries -  and represent a major uncertainty in the global carbon cycle. Yet, drylands are in zones of transition that will be affected by future global change, including drought and land degradation, with unclear consequences on global carbon and water budgets, ecosystem services and sustainable livelihoods. In this session we seek to i) highlight advances in our understanding of hydrological, biogeochemical and ecological processes in water-limited environments; ii) investigate the response of drylands ecosystems to changing climate, elevated CO2, and different land use and management practices; and iii) provide perspectives on needs and directions for future research. Contributions from both modeling and experimental studies across a wide range of fields are welcome.
