The 15th Franco-Japanese Symposium of Oceanography “Marine Productivity, Perturbations and Resilience of Socio-Ecosystems,� organized by the long-standing partners Société franco-japonaise dOcéanographie de France and Société franco-japonaise dOcéanographie du Japon, reviewed the impacts of natural (storms, typhoons, earthquakes, tsunamis, etc.) and man-made (pollution, buildings in coastal areas, aquaculture, tourism, sports, diving, etc.) perturbations inflicted on coastal and marine environments. The Symposium examined the resilience of affected socio-ecosystems along with governance responses for these global/local environments. This book collects 43 selected papers, written by experts from numerous universities and research institutes in both countries. It addresses the needs of marine sciences researchers (natural and social sciences), decision-makers and coastal zone managers, and other stakeholders involved in coastal and marine socio-ecosystems.
