A new project has reignited tensions in Notre-Dame-des-Landes, as parts of the area are set to be used for environmental compensation linked to the construction of a new administrative detention center (CRA) in Nantes. The prefect of Loire-Atlantique issued a building permit and environmental authorization earlier this summer for the CRA, which is scheduled to be completed by the end of 2027. The CRA will be built on more than 5 hectares of land between the north of Nantes and the commune of Carquefou, requiring the concreting of parts of a forest and a wetland. The prefect has identified areas in Notre-Dame-des-Landes and Vigneux de Bretagne for compensation purposes. Residents of Notre-Dame-des-Landes, a region that has long resisted development projects, learned that part of the area would be used to offset the destruction of one of the last urban forests in the north of Nantes. The project was initiated by Gérald Darmanin in 2022. Two weeks after issuing the building permit, the prefect granted the environmental authorization on September 1, 2024. The authorization mentioned that several sites would be used for "compensation and/or support measures." Among these are parcels in the La Freusière area of Notre-Dame-des-Landes, which are owned by the state. Residents have criticized the project, calling it absurd and cynical. Benjamin Cuena, a member of the Colère CRA coordination group, stated that these lands were preserved from concrete after years of struggle to support agriculture, and now the state wants to use them again to justify the construction of the CRA. Manu, a resident of the ZAD (zone à défendre, or "area to defend"), said the government's use of the term "compensation" is misleading, noting that the affected parcels are cultivated in a reasoned manner and that the paths and hedges are maintained. The prefect justified the planned actions in Notre-Dame-des-Landes and Vigneux de Bretagne as involving the "renaturation of areas currently degraded." The measures include the de-artificialization of soils, the removal of fill, the decompaction and amendment of agricultural land, the reinforcement of hedges, and the collection of waste. The prefect also cited "support measures" such as the development of "free-evolving wooded plots" to promote biodiversity and soil fertility. These actions, according to the prefect, are intended to preserve agricultural activity and have a very positive impact on the ecological quality of the territory, surrounding waterways, and biodiversity. Opponents of the project argue that the compensation is ineffective, pointing out that the parcels in Notre-Dame-des-Landes are located tens of kilometers from the future CRA. Benjamin Cuena questioned how it is possible to consider compensating for the destruction of the only green oasis for residents by rehabilitating land dozens of kilometers away. Manu recalled years of mobilizations, stating that the CRA and its perceived racist policies are exactly the kind of world they do not want. Residents of the ZAD in Notre-Dame-des-Landes plan to conduct a collective sowing on October 10 on the parcels targeted by the compensation project, with the aim of making a strong political and agricultural gesture against the project.
