Multi-scaling for sustainability transition : the case of R-Urban in the Parisian suburb of Colombes

The past fifty years have seen an increasing acknowledgment of global sustainability challenges as well as a growing desire to transition towards greater sustainability. The objective of this thesis is to explore the potential for linking global challenges and local actions associated with a multi-scale approach to sustainable development, through the investigation of the putatively multi-scale project R-Urban in the Parisian suburbs. To reach this objective, a six-months internship with the project's initiators was used as a mean to observe, interview stakeholders and analyse the literature associated with the project.
