Abstract
The “occupation movement” of the ZAD of Notre-Dame-des-Landes fights since 2009 with the “citizen associations” and the “peasants in struggle” to preserve a humid hedgerow situated in the region of Britanny (France) against the building of an international airport. The social organization of the “Zone of Definitive Autonomy” is based on a radical critic of political representation which fosters a perspective of emancipation, a perspective of autonomy. This thesis in political sociology explores its effects on the formation of an alternative “être-en-commun” (“being-in-common”) through practices of socialization and justice, economical and cognitive exchanges, decision making processes and power relationships. This theoretical analysis of the materialization of “another possible” is based on an ethnographic fieldwork conducted between 2013 and 2014. Combining a pragmatic approach to the theory of forms mobilized by social network theories, this thesis adds a fragment to the deconstruction of the “governmental prejudice” the anarchist social science researches have undertaken. Through the study of a series of controversies which have been raised by the occupants during my fieldwork, I insist on the irreducibility of a set of tensions which shape a social life based on an important process of individual differentiation.
