An ecosystem-wide approach for assessing the spatialized cumulative effects of local and global changes on coastal ecosystem functioning

Abstract Coastal ecosystems are subjected to an increasing number of anthropogenic drivers, including marine renewable energies and climate change (CC). These drivers can interact in complex ways, which may lead cumulative effects (CEs) whose potential consequences on the need be addressed. We used a holistic approach—ecological network analysis (ENA)—coupled with two-dimensional food web model—Ecospace—to conduct ecosystem study CEs CC plus operation offshore wind farm functioning extended Bay Seine (English Channel). Mapped ENA indices showed that were not restricted area, i.e. where concomitant. varied both space among properties, displaying distinguish between different pathways modify multiple ways. Moreover, seemed tied structuring role CC, differed under 2050 2100 conditions. Such changes resulted stronger loss resilience conditions despite benefits reef reserve farm.
