| الوصف: | Within the European water framework directive (WFD), the status assessment of littoral waters is based both on the chemical quality and on the ecological quality of each water body. Quality elements enabling to assess the ecological status of a water body are, among other things, biological quality elements (phytoplankton, macroalgae, angiosperms, benthic invertebrates, fish), for each of which the member states have developed quantitative indicators. This document is one of the deliverables of a multi-annual study intended to characterize the sensitivity of these biological indicators towards the various anthropogenic pressures exerted on the French Atlantic and Channel coast: ultimately, the goal is to establish a quantitative and predictive relationship, statistically robust, between the WFD indicators used along the French channel and Atlantic coastline, and various anthropogenic pressures acting on these coasts. The aim of the WFD is indeed to restore or maintain a good chemical and biological quality of coastal waters, and thus to limit the impact of human activities potentially responsible for the degradation of ecosystems. This understanding of the linkages and interactions existing between anthropogenic pressures and ecological status of water bodies is therefore essential to identify priorities for action (challenges, substances .), prioritize actions to implement within restoration programs (technical, fiscal, financial), but also to be able to communicate constructively and persuasively in talks between managers and the various stakeholders of coastal regions. Using the DPSIR methodology, this literature analysis has permitted to identify, for each WFD biological quality element (except fish), which pressures (or pressure types) are potentially relevant in the light of their impact on the indicators of the ecological status of water bodies. Some metrics and indicators of anthropogenic pressures used in the literature to characterize the sensitivity of the biological quality elements, within ... |
