Des océans indigestes : l’émergence de l’eutrophisation côtière comme problème environnemental global

Despite harmful impacts on coastal communities and biodiversity for a few decades, eutrophication of marine systems only recently gained public visibility. Representing a major land-based pollution, it is now considered as the most striking symptom of intractable disruption of biogeochemical nutrien...

description	Despite harmful impacts on coastal communities and biodiversity for a few decades, eutrophication of marine systems only recently gained public visibility. Representing a major land-based pollution, it is now considered as the most striking symptom of intractable disruption of biogeochemical nutrients cycles at a global scale, due to massive phosphate ore extraction and industrial synthesis of reactive nitrogen. The ambition of this article is to account for the protracted emergence of coastal eutrophication as a public problem. Based on a comprehensive literature review of previously dispersed works in sustainability, social and political sciences, the article analyses multi-scale dynamics of ocean overfertilization.
