Contribution géographique à la démarche d'évaluation environnementale dans le cadre de grands projets d'infrastructures linéaires : l'exemple du projet Seine-Nord Europe

Abstract : This thesis is led by difficulties experienced by planners during linear infrastructure studies and developments. In the present context, they have to ensure a successful project without any extra cost while also taking into account environmental issues at different scales, as natural habitats and biodiversity protection. Until recently, these issues were not a main source of concern and studies were carried out to simply cover regulatory requirements as environmental assessment. Nevertheless, since The Grenelle Environment Forum, environment concerns have been considered as a key challenge for linear infrastructure projects in spite of difficulties due to a lack of process and efficient tools. Therefore this thesis provides an environmental assessment analysis based on environmental and experimental spatial planning geography and focused on the North-Seine canal project with some inconsistencies from European to local scale. Firstly, based on the description and analysis of this project, this thesis is a contribution to the knowledge improvement of planning strategies and the way they take into account environment issues: biodiversity and natural resources and environment protection are the main environmental concerns. Furthermore, this thesis is also designed as an “action research” and a help for project planners and managers with effective help. Three different ecological vulnerability assessment tools have been created to analyze natural resources and environments along the route proposition and they are described in this paper.
