'Nouvelles croyances, nouvelles valeurs'-Incorporer une interprétation hétérodoxe du concept de services écosystémiquesdans la planification environnementale locale et la prise de décision

摘要: This paper explores the theoretical argument for embedding a ‘heterodox’interpretation of the ecosystem services (ES) concept in environmental planning and decision-making at the local scale. The paper adopts as it key premise that the uncertainties and knowledge gaps that emerge when the ES concept is taken beyond its mainstream interpretation can motivate planners and their stakeholders to “think harder and deeper” about why they value their ecosystems. This invites actors to question their settled beliefs about how they live from, with and in their local environment–now and in the future. Drawing from Peirce’s theory of abduction and Ostrom’s theory of self-organisation, the paper develops a constructivist perspective on local environmental planning and decision-making. It also presents empirical findings from a first case study in the Thau lagoon, Southern France.
