[H-CG28] [EE] DELTAS: multidisciplinary analyses of complex systems

Wed. May 24, 2017 9:00 AM - 10:30 AM 106 (International Conference Hall 1F)

convener:Yoshiki Saito(Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology), Paola Passalacqua(University of Texas at Austin), Kazuaki Hori(Department of Geography, Graduate School of Environmental Studies, Nagoya University), Efi Foufoula-Georgiou(University of Minnesota), Chairperson:Yoshiki Saito(Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology), Chairperson:Kazuaki Hori(Department of Geography, Graduate School of Environmental Studies, Nagoya University), Chairperson:Efi Foufoula-Georgiou(University of Minnesota)

Deltas account for approximately 1% of global land area, but are major sinks of sediments from rivers and home to more than 500 million people. They play a key role in global material cycles, agricultural and aquaculture production, food security, and commerce - yet, deltas are amongst the world's most threatened socio-natural systems, a situation projected to amplify in the 21st century due to both natural and anthropogenic impacts on the environment.

This session invites contributions that advance research on deltas as complex systems, develop integrated frameworks for delta dynamics modeling on various time-scales, explore quantitative metrics of vulnerability and resilience of social-ecological systems, promote data collection and sharing for advancing science and local solutions, consider policy and governance issues linked to the sustainable development of deltas, and use in-situ and satellite data for guiding modeling and risk assessment. Analysis of current challenges under projected scenarios of change of specific deltas, and knowledge gaps in science, data, and management/policy to achieve pathways to desired delta futures are especially welcome.

This session contributes to the International Council of Science (ICSU) "Sustainable Deltas 2015" initiative aiming to promote international scientific collaboration, knowledge and data exchange, and foster science-policy interactions for a sustainable future of threatened deltas and "Future Earth".
