R\u00e9sum\u00e9 :<\/strong><\/p>\n\n\n\n

La densit\u00e9 des controverses qui les entourent, leur inscription territoriale tr\u00e8s marqu\u00e9e, la difficult\u00e9 \u00e0 en venir \u00e0 bout tendent \u00e0 accentuer le caract\u00e8re exceptionnel et sp\u00e9cifique des mar\u00e9es vertes. Et pourtant, l\u2019\u00e9tude de leur trajectoire en tant que probl\u00e8me public peut permettre de d\u00e9celer des traits communs avec un ensemble de \u00ab crises \u00bb environnementales qui s\u2019\u00e9ternisent. Du fait du degr\u00e9 croissant de sp\u00e9cialisation de la recherche scientifique, du fait \u00e9galement de la multiplicit\u00e9 des alertes environnementales, rares sont cependant les chercheur\u00b7es en mesure de mettre en perspective ces trajectoires et de les faire dialoguer entre elles. C\u2019est le cas de Bernard Chevassus-au-Louis, agr\u00e9g\u00e9 de sciences naturelles, docteur \u00e8s sciences, pr\u00e9sident de l\u2019association reconnue d\u2019utilit\u00e9 publique Humanit\u00e9 et Biodiversit\u00e9 et ancien membre du Conseil g\u00e9n\u00e9ral de l\u2019alimentation, de l\u2019agriculture et des espaces ruraux (CGAAER). C\u2019est en cette derni\u00e8re qualit\u00e9 qu\u2019il a eu l\u2019occasion d\u2019expertiser, au tournant des ann\u00e9es 2010, les connaissances produites sur les causes des ph\u00e9nom\u00e8nes de prolif\u00e9rations d\u2019algues vertes, et d\u2019en proposer un bilan<\/a> qui n\u2019a rien perdu de son acuit\u00e9.<\/p>\n\n\n\n

Au cours d’une longue carri\u00e8re de chercheur ou de responsable d’\u00e9quipe de recherche dans diverses organisations publiques (INRA, AFSSA devenue ANSES, CIRAD, MNHN), Bernard Chevassus-au-Louis a \u00e9t\u00e9 impliqu\u00e9 dans diverses crises au cours desquelles la science \u00e9tait interrog\u00e9e, mais aussi souvent contest\u00e9e, pour \u00e9clairer la soci\u00e9t\u00e9 ou la d\u00e9cision publique (vache folle, mar\u00e9es vertes, OGM, pesticides, \u00e9rosion de la biodiversit\u00e9, d\u00e9r\u00e8glements climatiques…). Ces contestations ont pris des formes diverses, mais on peut aussi identifier dans cette diversit\u00e9 des \u00ab\u00a0figures\u00a0\u00bb ou des \u00ab\u00a0registres\u00a0\u00bb communs qu\u2019il propose de pr\u00e9senter, comme \u00e9tant des mat\u00e9riaux empiriques que les sciences sociales pourront \u00e9ventuellement mettre en forme et analyser.<\/p>\n\n\n\n

Rendez-vous GreenSeas #2 – Are green tides a contemporary environmental problem just like any other?<\/em><\/h1>\n\n\n\n

The ANR GreenSeas research project team is pleased to invite you to the second session of Rendez-vous GreenSeas. This series of webinars is an opportunity to invite national or international specialists to present their work on topics central to the project. This second webinar will take place online and in person on Thursday 23rd October from 10:00 to 12:00. We will focus on the trajectory of green tides as a public issue.<\/em><\/p>\n\n\n\n

Abstract:<\/strong><\/em><\/p>\n\n\n\n

The density of the controversies surrounding them, their very marked territorial nature, and the difficulty in overcoming them tend to accentuate the exceptional and specific nature of green tides. And yet, studying their trajectory as a public issue can reveal common features with a series of long standing environmental \u2018crises\u2019. However, due to the increasing degree of specialisation in scientific research and the multiplicity of environmental alerts, few researchers are able to put these trajectories into perspective and establish a dialogue between them. This is the case for Dr Bernard Chevassus-au-Louis, professor of natural sciences, president of the recognised public interest association Humanit\u00e9 et Biodiversit\u00e9 and former member of the French General Council for Food, Agriculture and Rural Areas (CGAAER). It was in this latter capacity that, at the turn of the 2010s, he had the opportunity to assess the knowledge produced on the causes of green algae blooms and to propose an assessment that has lost none of its relevance.<\/em><\/p>\n\n\n\n

During a long career as a researcher and research team leader in various public organisations (INRA, AFSSA, now ANSES, CIRAD, MNHN), Bernard Chevassus-au-Louis has been involved in various crises during which science was questioned, but also often challenged, in order to enlighten society or public decision-making (mad cow disease, green tides, GMOs, pesticides, biodiversity erosion, climate change, etc.). These challenges took various forms, but common \u2018patterns\u2019 or \u2018registers\u2019 can also be identified in this diversity, which he proposes to present as empirical material that the social sciences could potentially shape and analyse<\/em><\/p>\n\n\n\n

The presentation will be in French<\/em><\/p>\n\n\n\n
