Synthetic evaluation of territorial sustainability : strengths and weaknesses of modeling in the planning process

subject

description

This thesis work is based on issues aimed at assessing the impacts of planning decisions in the light of the imperatives of sustainable development. Beyond the vagueness that often emerges from this concept, the aim here is to reflect on a better balance to be found between the three fields generally identified as pillars of sustainable development: the economic, the social and the environmental. The objective is part of the following reflection: how to evaluate the impacts of management policies in each of these three pillars, and what conclusions to draw from them? The aim here is to provide answers by assessing the performance of the territories studied in these three pillars of sustainable development. For this, the work relies on the outputs of the simulation models (here, the MobiSim model developed within the ThéMA laboratory) and the production of synthetic indicators allowing analysis and a readable evaluation of the space.The combination of these synthetic indicators makes it possible to visualize and analyze the sustainability of the territory studied and to deduce the appropriate measures to implement in order to ensure a sustainable development policy. It is thus a question of putting in perspective the methodology and the results obtained in a global vision, seeking to establish by the balance between the three spheres a harmony which makes it possible to satisfy the objectives of a policy guided by the imperatives related to the sustainable development conceptinherited from the Brundtland report. A critical approach to this concept and an analysis of the games of actors of a territory are conducted here in order to implement the scientific research work within a decision process. The challenge is to enable results of research work based on modeling tools to be able to find a more concrete and more operational outcome.
