Reconversion et aménagement durable des friches urbaines polluées : élaboration d'une méthode participative d'évaluation et d'aide multicritère à la décision

Abstract : Brownfield redevelopment is a key priority topreserve soils. Brownfields are often contaminated yet.Therefore, it creates numerous obstacles to reuse them.Firstly, brownfields redevelopment’s benefits areunderestimated whereas costs are overestimated bydevelopers. Secondly, brownfields are plagued with thestigma effect. This effect persists even after remediationprocess (e.g., individuals may not use facilities on aformer contaminated brownfield). Thirdly, new uses cancause conflicts between the stakeholders. As such, thisthesis deals with contaminated brownfieldredevelopment taking into account both themultidimensionality of stakeholders, their preferencesand their perceptions. developers. In a first part, we study barriers to brownfieldredevelopment and how to tackle them using a surveyamong 76 French developers.In a second part, weanalyse the importance of the stigma associated withcontaminated brownfields. A first survey (803observations), conducted at national level, investigatesindividuals’ perceptions, representations and preferencesregarding brownfield redevelopment. A second survey(338 observations), conducted among five municipalitiesimpacted by such sites, specifies their preferences usinga discrete choice experiment. In the third part, we applya participatory multicriteria decision aid. It determinesthe most consensual projects in the case of acontaminated site. They correspond to individuals’preferences that were previously analysed.
