La Bretagne face aux industries extractives. Processus de cadrage et construction de coalitions contre la prospection minière et l'extraction de sable dans les Côtes d'Armor.

Starting in 2016, in the Côtes d'Armor district, in French Brittany, two natural resources extraction project face strong local mobilizations. The first one is the Loc-Envel mining project, in the countryside, and the second one is a shell sand extraction licence, on the coast. Although those two struggles are rather close to each other, they take different shapes : while the mobilization against the Loc-Envel mining project takes the form of a flexible coalition, the one against the shell sand extraction is structured in a coalition organisation (Staggenborg, 1986). How can we explain these differences in such a small area ? In order to answer this question, this article looks at the role of local heritages and framing in the shaping of environmental conflicts. Thereby, we find a counter-expert approach on the coast and a territorialized one in the countryside, while the criticism of extractivisme (Bednik, 2016) remains marginalized. [ABSTRACT FROM AUTHOR]
