How can traditional community management methods be used to co-build an integrated marine and coastal management approach as part of an integrated maritime strategy?


  1. Integrated and multi-stakeholder approaches at different scales.
  2. Projects combining nature and culture
  3. Projetcs of participatory science.


Terms of reference:  The development of integrated approaches and large-scale habitat restoration programs that integrate all stakeholders is a long-standing concept in Japan, based on local development. This is evidenced by the concept of “Sato-Umi” (sea and man in harmony), itself derived from the much older “Sato-Yama” (mountain and man in harmony). These two concepts evoke a very strong link between nature and culture on which the sustainable exploitation of an environment that is the fundamental base of food supply but also cultural heritage. In Europe, and particularly in France, there are still a number of similar traditional practices, particularly in the field of small-scale fisheries.This session will allow to develop a number of outstanding examples existing in France and Japan, but not limited to, around the coastal ecosystems management with an ecosystemic or patrimonial approach.

How to ensure uses co-existence and preserve the resilience of traditional activities such as fishing and shellfish farming facing new activities in a context of global change. To this end, how to promote a process of dialogue between stakeholders (including decision-makers) in the frame of an integrated ecosystem-based management approach including marine spatial planning ?


  1. Sharing of spaces and diversity of uses: Marine protected areas, development of marine renewable energies, seaside tourism.
  2. Mitigation processes: development of artificial reefs and restocking experiments, restoration of key habitats, minimization of the ecological footprints of marine fisheries and aquaculture.
  3. Development of the fisheries and aquaculture sector.

Terms of reference:  Blue energy development in France or more widely in Europe, within the framework of the energy transition policy, is a new space consuming activity that creates new ecosystem services. In parallel, an increasing surface of marine protected areas are designed to preserve environment, biodiversity and resources. In New Aquitania this is reflected by the creation of 2 marine parks: the Bassin d’Arcachon and the Estuary of the Gironde-Mer des Pertuis. It will highlight the steps taken by actors in the establishment of a dialogue  for the setting-up and management of marine protected areas, marine parks, wind farms, development of migratory fish systems and  concerted management at the scale of the watershed and its  adjacent coastal zone. Techniques for minimizing the ecological footprints of different uses on coastal and estuarine ecosystems will be discussed. Emphasis will be placed on actions to develop farmed or wild seafood, restocking or enhancing habitat experiments and to increase the selectivity of fishing gears and their impacts on the sea floor.

How to implement an integrated management approach for these interface and land-sea transition areas in order to minimize synergy of impacts from different uses and better adapt to the factors of change?


  1. Estuarian and coastal fisheries
  2. New and traditional aquaculture.
  3. Restocking, fattening and fishery

Terms of reference:  The temperature rise combined with the organic enrichment of coastal waters (and bay sheltered areas) can (i) reduce species productivity, which supports economical activity as inshore fishing activity and (ii) increase the frequency of epizootics detrimental to the development of aquaculture or tourism activities. Acidification of marine waters may also have a direct impact on the development of shellfish species or crustaceans and more broadly on the specific composition of trophic chainsThat session is dedicated to living resources and their management. For fisheries, we will try to show how the fishing industry can adapt to the factors of change (change of biocenosis, fluctuations in abundance), taking as an example emblematic species such as bluefin tuna, eel  or amberjack in Japan, but not limited to. For aquaculture, there will be a link between the quality of the environment and the productivity of the cultivated species, the impact of global change on production cycles, the frequency of epizootics, fluctuation in spat collection and spat mortality. Efforts will be made to identify new forms of production such as those linking fishing and restocking (eg. amberjack or eel for example) or fisheries and aquaculture (eg. bluefin tuna or amphihalin fish).

How can today’s socio-ecosystems be resilient to adapt tomorrow not only to coastline changes, but also to natural disasters increasing frequency and strength on the coast?


  1. Protection of coastal and estuarine environments and socio-ecosystems.
  2. Effects and impacts of coastal deterioration, estuary and river channelling and coastal urbanization


Terms of reference: Coastal areas are, in general, heavily exploited ecosystems. They account for about 2% of the Earth’s land surface but are home for 10% of the world’s population in low-land areas, resulting in a very high vulnerability to natural hazards: tsunamis, floods, marine intrusions, cyclones that caused considerable material damage and thousands of casualties, with large-scale environmental, social and economic consequences. Japan, one of the world’s leading seafood producers, surrounded by particularly productive seas despite a highly urbanized coastline, and faced with particularly frequent natural cataclysms, has nevertheless managed to safeguard an important part of its coastal maritime economy and, as such, is a privileged interlocutor for exchanging and undertaking joint research with French and European scientific and professional actors in the maritime sector. The objective of that session is  to illustrate effects of natural disasters and sea intrusions and  means used to limit their impacts, as well as the impact of territorial planning on the characteristics and productivity of coastal and estuarine environments.

  3. Renewable maritime energies.
  4. Ecosystemic and integrated approaches including the analysis of the effect of marine protected areas and marine parks.

Terms of reference:  How to implement management policies at different scales whose purpose is to guarantee a more ecological governance for a more human conservation. How to establish a harmonious cohabitation of the different uses in a space subjected to multiple constraints. Some EU Framework Directives such as the WFD (Water Framework Directive), the MSFD (Marine Strategy Framework Directive) and the recent SMPD (Framework Directive for the Spatial Marine Planning) make it possible to evaluate the good state of inshore, estuarine and coastal water masses, to measure the impacts of anthropogenic pressures and to establish co-habitation policies for coastal marine uses up to the limit of the Exclusive Economic Zone (EEZ). Japan refers to its “basic plan for the Environment”. These guidelines are based on transdisciplinary scientific studies, in an integrated ecosystem approach, foreshadowing what might be a coastal and operational oceanography, aimed at feeding the Integrated Sea and Coastal Management (ISCM) approach and political decisions that relate to it. This is the topic of the fourth session. Here the term “communities” is taken in a broad sense and refers to both animal and plant communities and human communities.

Vulnerability of coastal ecosystems and risk assessment.


  1. New tools and networks for observation and modeling.
  2. Role of research in operational approaches (eg: Operational coastal oceanography, MSFD, WFD,…).
  3. Risks to resources and ecossystems.
  4. Risks to human health (chemical and biological aspects).
  5. Ecosystem resilience.

Terms of reference:  In a context of rapid change, human societies are planning their future actions to reduce the pressures and / or adaptation factors by integrating the constraint of the impacts suffered. It is therefore particularly crucial to identify and better understand the relationships between factors of environmental pressure accumulated at different scales of space and time and their current or potential impacts. These relationships may be analyzed during this third session in terms of hazard probabilities, vulnerability and risks both on biodiversity and on the socio-ecosystems.

Impacts on socio-ecosystems and biological resources


  1. Marine ecosystems under pressure of climate change.
  2. Coastline and coastal ecosystem modifications.
  3. Coastal ecosystems under toxic pressure.
  4. Impact of global change on marine living resources and their exploitations.

Terms of reference:  Due to sea-level rise, the occurrence of extreme events (storms, tsunamis), and human activities, coastal areas are extremely vulnerable to erosion. On the other hand, coastal ecosystems undergo warming and modification of physical, chemical and biological characteristics of waters (warming, marine intrusion, acidification). Furthermore, they are often the receptacle of many sources of chemical and biological pollution which, in addition to global and regional pressures, degrade them and significantly reduce their resilience and ecological functions, based on a very high density and diversity of marine organisms. This second session will focus on the analysis and quantification of impacts at different scales of time and space and at different levels of complexity on the biological resources and socio-ecosystems that depend on them.

Identification and analysis of environmental stressors.


  1. Climate-ocean and ocean-atmosphere interactions, from global to local.
  2. Changes in biogeochemical cycles, coastal inputs and  acidification of seas and oceans.
  3. Biological and chemical pollutions.
  4. Sea level, littoralization and artificialization of the coastal strip

Terms of reference: Coastal and estuarine environments are highly productive ecosystems that are interconnected and constrained by more oceanic (sea basin) and more continental (watershed) environments, which are themselves subject to the pressure of global climate change and influences of local and regional anthropogenic factors. This symposium session will focus on the  identification, quantification and analysis of pressure factors, from global to local level, and assessment of their individual and potential combination effects.
