Participative multi-criteria analysis for the evaluation of water governance alternatives. A case in the Costa del Sol (Málaga)

This paper presents the results of a participatory multi-criteria evaluation of urban water supply alternatives in Costa del Sol Occidental in Málaga (Spain). Multi-criteria and social research techniques were combined, relying on social actors' involvement throughout the research work. The paper documents that participatory processes allowed to unveil framings, perspectives, values and interests, as well as understanding of the social and institutional context in which the waters are governed. The deployment of this methodological approach has in this case provided an extended diagnosis which was the starting point to explore non a priori foreseen management alternatives by the researchers. The methodological approach proved useful for problem structuring in a collective, flexible and iterative way, unveiling existing water management conflicts and their motivations, and improving the quality and effectiveness of the information exchange and the reflection process, among social actors, even if the whole process developed in a research setting rather than in a policy for real one. Participatory multi-criteria evaluation could in this case, contribute to identify policy options that could be better defended before all the social actors, including the general public, thus attempting to achieve shared ground. The paper suggests some methodological considerations for applying participatory multi-criteria evaluation based on the outcomes of the case study application.
