Mediterranean seagrass meadows : resilience and contribution to climate change mitigation, a short summary = Les herbiers de Magnoliophytes marines de Méditerranée : résilience et contribution à latténuation des changements climatiques, résumé

This document is a summary of the technical report on the current state of affairs in the Mediterranean basin. It describes the specific characteristics of the Mediterranean Sea and the phenemenon of climate change observed on the scale of this particular region. It then presents five species of Magnoliophyta documented in its waters. Secondly, it describes the impact of climate change on Mediterranean seagrasses, firstly with regard to the pressures to which they are subjected and their resilience to them and, secondly, to the communities associated with the marine environments they form. The last part of the document is devoted to the role played by seagrass meadows in the mitigation of the consequences of climate change, in respect of extreme weather events and the fixation and sequestration of blue carbon. Ce document est un resume du rapport technique relatif a l’etat de la question dans le bassin mediterraneen. Il decrit les specificites de la mer Mediterranee et le phenomene du changement climatique observe a l’echelle de cette region. Il presente ensuite les caracteristiques des cinq especes de Magnoliotphytes presentes dans ses eaux. Dans un second temps, il decrit l’impact du changement climatique sur les herbiers Mediterraneens, d’abord en ce qui concerne les pressions qu’il y exerce et leur resilience a ces pressions, et ensuite en ce qui concerne les communautes qui leur sont associees. La derniere partie du document est consacree au role joue par les herbiers dans l’attenuation des consequences du changement climatique, en prenant en compte les evenements climatiques extremes et la fixation ou la sequestration du carbone bleu.
