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?

Keywords:

  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 ?

Keywords:

  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?

Keywords:

  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?

Keywords:

  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.
