      • Discover the content of the session: "Sedimentary environments and human activities: Management of dredged sediments, extraction of aggregates, marine renewable energy and sustainable ports"

      • Maritime transport and, more broadly, human activities at sea and on land generate pollution and nuisances in the marine environment and on the coast that need to be controlled: discharges from activities in the catchment area, discharges from maritime and port activities (dredging, careening, maritime traffic, ...), accidental pollution, disturbance of habitats, etc. The objective of this session is to present different actions, such as those carried out by Cerema or Ifremer, in the framework of its missions to support the implementation of environmental public policies in port and coastal areas.
        Experts from the various sectors will be able to present: 1) the ecological transition of activities and actions to reduce pollution/impacts (e.g. port greening operations, environmental protection, ...); 2) the monitoring of sediment quality (port or other) or the monitoring of the effects and mitigation « ERC » measures (avoidance, reduction, compensation) of activities (extraction of aggregates, development of MRE); 3) beneficial uses of dredged sediments and the circular economy (valorisation of dredged sediments on land and at sea); and 4) European and international recommendations, changes in the regulatory framework, technical recommendations, prospects for development and inclusion of these activities in European directives, etc.
