Constraints and Adaptations to Global Change at the Land-sea Interface for a Shared Ecological and Energy Transition: Proceedings of the 19th French Japanese Oceanography Symposium

Coastal or semi-enclosed seas, coastal or interface zones between land and sea are areas widely coveted by numerous human activities. These activities do not assess the effects and impacts of their cumulative pressures on the natural environment: coastal development, tourism, terrestrial pollution, maritime transport, dredging and piling, extraction of marine aggregates and development or planned development of marine wind farms or tidal turbines. In this context and despite the high productivity of these ecosystems, fishing and shellfish farming, which also exert their own environmental pressures, have some difficulties in ensuring their sustainability in an increasingly man-made environment and generating increasingly exacerbated conflicts of use.

The symposium will address some aspects of resilience (via their capacity to adapt to global change) of these coastal ecosystems and adaptation of human communities to climate change in a context of full use of natural resources.

A more holistic approach to the impact of all uses on the environment to ensure a more optimal management of the Commons, needs to be implemented. In Japan, the concept of Sato-umi (harmony between the coastal sea and local communities) is being implemented and incorporates participatory science and active restoration projects in an integrated coastal zone management framework.

Patrick Prouzet is a specialist in the biology and dynamics of diadromous species like European eel and Atlantic salmon. He holds a PhD in biological oceanography and a post-graduate qualification in research. His research focuses on the impact of global change on the management and restoration of diadromous species. He advises fisheries bodies in France and Japan within the Satoumi and Satoyama framework.

Professor Emeritus Jean-Claude Dauvin is a distinguished Professor Emeritus and Officer of Maritime Merit. He serves on the editorial boards of the Marine Pollution Bulletin and the Journal of Marine Science and Engineering. His research at Caen Normandy University focuses on benthic and suprabenthic communities, marine ecosystem conservation, marine invertebrates, Marine Renewable Energy, and taxonomy of amphipods and polychaetes. He has authored or co-authored around 350 international peer-reviewed papers.

Teruhisa Komatsu specializes in coastal marine ecology, particularly seagrass and seaweed beds. He has conducted ecological studies on Caulerpa taxifolia and Posidonia oceanica. He leads the “Ocean Remote Sensing Project for Coastal Habitat Mapping” and conducts satoumi research on the recovery of the Sanriku region after the 2011 tsunami. He is the president of the SFJO Japan Chapter.

Eric Feunteun is a Professor of Marine Ecology at the French Museum National d’Histoire Naturelle (MNHN) and EPHE. He specializes in the conservation ecology of marine ecosystems and migratory fish, particularly the eel. His research includes the cumulative effects of offshore wind power on coastal ecosystems. He has been involved in the designation and management of Marine Protected Areas and acts as an expert in European framework directives.

Anne-Claire Bennis is a Full Professor of Marine Physics at the University of Caen Normandy. She specializes in the coastal environment and its interactions between hydrodynamics, sediments, and biology/ecology. She is a numerical modeler and chaired the scientific committee for the COAST 2023 event.

Osamu Matsuda is a Professor Emeritus of Hiroshima University and President of the Satoumi Research Institute, Japan. He specializes in the environmental management of enclosed coastal seas, nutrient cycles, eutrophication, environmental restoration, and Satoumi creation. He has worked extensively in field research, including Japanese Antarctic Research Expedition and projects in arctic and tropical areas. He has been involved in various international environmental initiatives and projects.
