Résumé
Forest regeneration is a major land-use change in European uplands, and whether or not this is a desirable change for biodiversity is disputed. While this debate seems to be largely situated in the field of natural sciences, this paper aims to also examine its social dimensions. To do so, we adopt a comparative discourse analysis with four cases of protected areas in France, Spain, and Scotland. We draw on a conceptual framework highlighting both the ecological and social factors underpinning the construction of environmental discourses. It notably emphasises the role of interests, ideas and institutions, and the power dynamics underpinning discourse-coalitions. We show how diverging discourses emerged, gained ground, coalesced and competed differently in different contexts, explaining the adoption of seemingly opposite discourses by protected area authorities. These findings reaffirm the need to conceive environmental governance as an on-going deliberative process in order to achieve environmental justice.
