A participatory decision support system for contaminated brownfield redevelopment: a case study from France

Currently, participatory evaluation processes using multicriteria decision aids are barely used in the context of contaminated sites, even though they are a powerful tool for supporting land-use decision-making. The aim of this paper is to show how to apply such a participatory evaluation process (mixed methods) to the redevelopment of a contaminated brownfield site in France. Following the Model for the Operationalization of Democratic Evaluation (MODE), we designed a participatory process that enabled stakeholder empowerment to implement participatory multicriteria evaluations. We show that the (Elimination and Choice Expressing Reality) ELECTRE I method can be used to select consensus-based brownfield redevelopment projects and that such a participatory process can be implemented to ensure that feasible, coherent, and transparent choices are made for other brownfield redevelopment processes.

当前，尽管基于多准则决策辅助（multicriteria decision aids）的参与式评估流程是支撑土地利用决策的有力工具，但在污染场地场景中却极少得到应用。本文旨在阐明如何将此类混合方法参与式评估流程应用于法国某受污染棕地（brownfield）的再开发工作。本研究遵循《民主评估操作化模型》（MODE）的框架，设计了一套可实现利益相关者赋权的参与式流程，用于开展参与式多准则评估。研究表明，采用ELECTRE I 法（Elimination and Choice Expressing Reality）可筛选出基于共识的棕地再开发项目，且此类参与式流程可推广应用于其他棕地再开发流程，确保最终决策具备可行性、一致性与透明度。
