Analyse de la prise en compte de la biodiversité des projets d’infrastructures de transport en milieu urbain : exemple du Tram 12 express

Abstract : In an environment of economic and social growth, the transport sector responds to the challenges of urbanization. Despite the socio-economic benefits of transport infrastructure, their impacts on the environment raise interrogations: habitat fragmentation, barrier effect, artificialization of soils, spread of invasive species, collision mortality, contamination, noise and light disturbances. The example of the Tram 12 express project was taken in order to evaluate globally the consideration of biodiversity and to analyze ecological monitoring more precisely during the construction phase. This overview of the project identifies its strengths and weaknesses to propose measures and ways to improve the integration of environmental issues into transport infrastructure projects. The analysis underscored the importance of early integration of biodiversity in the design phase to implement appropriate ERC (avoidance, reduction, compensation) measures. Ecological monitoring appears as an essential element of an effective consideration of biodiversity. It must be regular, thorough and must propose adaptations to the measures according to changes in ecological issues. The study proposes reduction measures to integrate vegetal elements beneficial to the biodiversity and to develop the educational interest of the project. Three main ways to improve the consideration of biodiversity are developed: a multi-stakeholder project design, a better impact assessment and measures to strengthen awareness on construction sites.
