With ecosystems worldwide being increasingly exposed to a multitude of human activities, assessing the cumulative impacts of anthropogenic activities has become an emerging challenge in terms of both environmental regulation and scientific research. The Scientific Interest Group GIS ECUME (“Groupement d’Intérêt Scientifique Effets Cumulés en Mer”: Scientific Interest Group on Cumulative Effects at Sea) was constituted in November 2020 with the objective to develop a scientific approach and methodology for assessing the cumulated impacts of marine human activities in the eastern part of the English Channel, one of the more anthropogenic zones in the world (marine aggregates, marine renewable energies, submarine cables, harbour dredging and deposition of dredged sediments, fishing activities and notably trawling). The group’s scientific priorities are to assess the cumulative impacts of these activities on hydro-sedimentary dynamics, underwater noise, as well as the artificial reef effect of submerged structures, the development of a methodology for cumulative effects assessment in environmental impact studies, and the social acceptability of human activities at sea. Coordinated by Caen Normandy University, the group assembles the main academic research institutions (Universities of Caen Normandy, Rouen Normandy and Le Havre Normandy) and all the main project holders (UNICEM, (Marine aggregate extractions (national union of marine aggregate extraction industries).) CRPMEM, (Fisheries (Regional Committee for Marine Fisheries).) RTE, (Submarine cables (Electricty Transport Network).) HAROPA PORT, (Ports of Rouen and Le Havre.)

EOHF (Éoliennes Offshore des Hautes-Falaises.)) with regard to the above-mentioned human activities at a regional scale. By promoting a close interaction between professionals and researchers, GIS ECUME facilitates the establishment of research projects as close as possible to the activities, which has led to the launch of the first research project on the sedimentary interactions of marine aggregates extraction and the deposition of dredged sediments in the Seine Bay, the development of a methodology for cumulative effect assessment, as well as on the acoustic impact of human activities at sea on fishery resources.

摘要

With ecosystems worldwide being increasingly exposed to a multitude of human activities, assessing the cumulative impacts of anthropogenic activities has become an emerging challenge in terms of both environmental regulation and scientific research. The Scientific Interest Group GIS ECUME (“Groupement d’Intérêt Scientifique Effets Cumulés en Mer”: Scientific Interest Group on Cumulative Effects at Sea) was constituted in November 2020 with the objective to develop a scientific approach and methodology for assessing the cumulated impacts of marine human activities in the eastern part of the English Channel, one of the more anthropogenic zones in the world (marine aggregates, marine renewable energies, submarine cables, harbour dredging and deposition of dredged sediments, fishing activities and notably trawling). The group’s scientific priorities are to assess the cumulative impacts of these activities on hydro-sedimentary dynamics, underwater noise, as well as the artificial reef effect of submerged structures, the development of a methodology for cumulative effects assessment in environmental impact studies, and the social acceptability of human activities at sea. Coordinated by Caen Normandy University, the group assembles the main academic research institutions (Universities of Caen Normandy, Rouen Normandy and Le Havre Normandy) and all the main project holders (UNICEM, (Marine aggregate extractions (national union of marine aggregate extraction industries).) CRPMEM, (Fisheries (Regional Committee for Marine Fisheries).) RTE, (Submarine cables (Electricty Transport Network).) HAROPA PORT, (Ports of Rouen and Le Havre.) Ports de Normandie, EODC, (Offshore wind energy (Eoliennes Offshore du Calvados).)

By promoting a close interaction between professionals and researchers, GIS ECUME facilitates the establishment of research projects as close as possible to the activities, which has led to the launch of the first research project on the sedimentary interactions of marine aggregates extraction and the deposition of dredged sediments in the Seine Bay, the development of a methodology for cumulative effect assessment, as well as on the acoustic impact of human activities at sea on fishery resources.
