Dans le sillon de Norbert Elias \u00e9tudiant la civilisation des m\u0153urs \u00e0 partir du mouchoir, L\u00e9o Magnin interroge l\u2019\u00e9cologisation des m\u0153urs \u00e0 travers un objet ordinaire : la haie. Car si les arbres et buissons ont une vie biologique bien connue, leur vie sociale mouvement\u00e9e reste \u00e0 d\u00e9couvrir. As the world becomes less habitable, are there signs that we are transforming the way we interact with the environment? Following in the footsteps of Norbert Elias, who studied the civilization of manners through the lens of the handkerchief, L\u00e9o Magnin explores the ecologization of manners through an unassuming object: the hedge. For if trees and bushes have a well-known biological life, their eventful social life remains to be discovered.<\/span> \nL\u00e9o Magnin<\/a> is a sociologist and a researcher at the CNRS at LISIS (Interdisciplinary Laboratory for Science, Innovation, and Society). The primary focus of his research is on analyzing the control of greening, addressing how legal categories, thresholds, and indicators are negotiated politically, the unintended effects of environmental monitoring policies, work activities involving digital tools, the phenomena that control techniques allow us to see and not see, as well as the way in which the powers to reward and punish are socially distributed in the agricultural world.

\nMassivement d\u00e9truites lors de la modernisation agricole apr\u00e8s 1945, les haies sont d\u00e9sormais pl\u00e9biscit\u00e9es en tant que r\u00e9servoirs de biodiversit\u00e9, puits de carbone, sources d\u2019\u00e9nergie renouvelable, freins \u00e0 l\u2019\u00e9rosion et trames paysag\u00e8res. Comment expliquer un tel revirement ? En enqu\u00eatant sur les traces de requalifications des haies : l\u2019inqui\u00e9tude exprim\u00e9e par un \u00e9leveur face \u00e0 leur protection, les h\u00e9sitations d\u2019un planteur dans sa parcelle, le co\u00fbt de l\u2019entretien, le go\u00fbt de l\u2019\u00e9lagage, l\u2019\u00e9tude scientifique du bocage, sa cartographie num\u00e9rique, son \u00e9tonnante politisation gouvernementale et villageoise, etc.
\nDes cours de fermes aux dorures minist\u00e9rielles, La Vie sociale des haies <\/em>investigue ainsi les diff\u00e9rentes dimensions du processus d\u2019\u00e9cologisation, dessinant les dynamiques sociales qui s\u2019essoufflent, se poursuivent ou se r\u00e9inventent \u00e0 l\u2019\u00e9preuve des enjeux environnementaux. Suivre le d\u00e9dale des haies \u00e9claire les zigzags de l\u2019histoire qui configurent les contradictions de notre pr\u00e9sent, mais aussi ses t\u00e2tonnements prometteurs\u2026<\/p>\n
\nHedges were massively destroyed during agricultural modernization after 1945 but are now widely acclaimed as reservoirs of biodiversity, carbon sinks, sources of renewable energy, erosion barriers, and landscape features. What explains such a reversal? Magnin investigates the traces of hedge requalification, such as a farmer\u2019s concern about protection, a planter\u2019s hesitations on his plot, maintenance costs, pruning preferences, scientific hedgerow studies, digital mapping, and the surprising politicization by governments and villagers.<\/span>
\nFrom farmyards to ministerial offices, La Vie sociale des haies<\/em> (The Social Life of Hedgerows) investigates the various dimensions of the greening process. It outlines the social dynamics that are running out of steam, continuing, or reinventing themselves in the face of environmental challenges. Following the maze of hedgerows sheds light on the twists and turns of history that shape the contradictions of our present, as well as its promising trials and errors.<\/span><\/p>\n![\"\"](\"https:\/\/i3.cnrs.fr\/wp-content\/uploads\/2024\/09\/Miniature-i3_Seminaire-invites-du-CSI-300x224.jpg\")
