Recommandations pour une approche écosystémique des aires d’implantation d’énergies marines renouvelables. Cas d’étude du parc éolien offshore de Courseulles-sur-mer 5

Les études d’impact environnemental menées en amont des projets éoliens offshores considèrent chaque compartiment de manière individuelle, et non pas l’écosystème dans son ensemble. La compréhension des liens trophiques et l’appréhension de l’écosystème de manière holistique est pourtant un enjeu important rapporté par les politiques publiques telles que la Directive Cadre Stratégie pour le Milieu Marin (Directive 2008/56/EC). Le projet collaboratif TROPHIK (ANR-10-IEED-0006-12) pose les bases d’une approche écosystémique des Energies Marines Renouvelables (EMR) destinée à permettre une démarche holistique et intégrée avant installation de parcs éoliens en mer. Cette approche s’appuie sur un cas d’étude français, le site du futur parc éolien au large de...

Cumulative effects of marine renewable energy and climate change on ecosystem properties: Sensitivity of ecological network analysis 5
Nogues, Quentin; Raoux, Aurore; Araignous, Emma; Chaalali, Aurelie; Hattab, Tarek; Leroy, Boris; Ben Rais Lasram, Frida; David, Valérie; Le Loch, Francois; Dauvin, Jean-claude; Niquil, Nathalie.
In an increasingly anthropogenic world, the scientific community and managers have to take interactions between the drivers of ecosystems into consideration. Tools like ecological network analysis (ENA) indices offer the opportunity to study those interactions at the ecosystem level. However, ENA indices have never been used to test the incidence of cumulative drivers. The present study uses models combining the effects of (i) the reef caused by the future offshore wind farm of Courseulles-sur-Mer and (ii) climate change on species distribution, to test the response of multiple ENA indices. ENA indices proved sensitive to this cumulative impact, displaying a wide variety of cumulative effects. They were also very powerful to characterize the role of the...
