Participation of stakeholders in MCDA: processes and tools
This contribution emphasizes the participation of stakeholders in the field of environmental assessment and more specifically their participation supported by a multi-criteria decision aid approach (MCDA) which could also be presented as a multicriteria aiding approach for consultation, deliberation or negotiation in view of a decision. In this regard, the system of actors for environmental assessment is presented. The processes involved must be aligned: planning, environmental assessment, participation, multi-criteria support. Environmental assessment is a complex field, where interdisciplinarity is a necessity which can judiciously be handled by a multi-criteria approach, where the stakeholders are potentially very numerous, and where the search for solutions and the related issues are often conflicting. The necessary prerequisites to implement a participatory and contributory approach are therefore specified. Stakeholder participation can take different forms depending on the MCDA methods that support environmental assessment. It can be more or less contributory depending on the degree of stakeholder involvement and also depending on the stages in which stakeholders are invited to participate. It can also be supported in a flexible and non-directive manner or even be more or less strongly framed. Depending on the resources available, participation can be facilitated by an expert member of the environmental assessment team or benefit from a facilitator, or even a mediator or negotiator. The advantages and disadvantages of insisting on the settlement of certain disagreements or conflicts upstream of the process or more downstream are presented. The emphasis is on sharing upstream the performance table of the scenarios analyzed or rather to postpone these questions at the end of the process, when providing the recommendations to the authority in charge of making the final decision to accept or not and under what conditions the proposal submitted for environmental assessment. Each step of the environmental assessment is discussed with regard to stakeholder participation, supported by a MCDA approach and the tools that can support that participation. From here, all the elements are treated within the framework of the PROMETHEE and GAIA multi-criteria methods implemented by the Visual PROMETHEE software. Of course, many elements are also applicable following other multi-criteria methods. The very first thus addresses the question of who participates and at what stages depending on the problem posed either at the project or strategic level (policy, plan, program). The concept of restricted societal participation is discussed. With regard to the stages of problem definition, namely: the identification of scenarios, issues, criteria and measurement indicators, collective working tools are proposed. With regard to the scenario performance table according to each of the impact criteria, the question of scientific knowledge, and local, contextualized, endogenous or traditional knowledge is addressed. Sometimes you also have to deal with data gaps or missing data. Proposals are made to take advantage of the available experts as well as the stakeholders involved. Regarding stakeholder preferences and priorities, a few tools are available. It is indeed not easy for the participants to establish the bases for comparing the scenarios on the same criterion according to the measurement scale used. They do not all have the same way of setting their preferences. Also, how to help them establishing their priorities among the issues and the criteria that reflect them. Should the criteria be weighted or not? If yes, how to proceed? Finally, the tools offered by Visual PROMETHEE help to facilitate discussions between participants. The contributions of each of these tools are presented, including the sensitivity and robustness analyzes essential to deal with indecisions, uncertainties or specific conflicts. The questions related to the sharing of results specific to each participant and to the group are discussed, as well as those related to the degree of interactivity of the participants with the Visual PROMETHEE software is also presented. All of these points are illustrated from case studies conducted by the author and the GEIGER team over the past 20 years.
