Gouverner les cours d'eau par un concept : Etude critique de la continuité écologique des cours d'eau et de ses traductions

Abstract : The restoration of European rivers has been aligned with the Water Framework Directive, which promotes the concept of river continuity.This con cept was codified in French law in 2006, whereby it was termed "ecological continuity of rivers" and defined as the free movement of living organisms and the efficient transfer of natural sediments. Since the 2012 , the ecological continuity of rivers has been one of the most significant policy developments affecting rivers in the country. However, efforts to restore or establish ecological continuity have been met with problems, including the opposition of local residents, which have given rise to disagreements. In an effort to better understand these oppositions, this dissertation traces the socio-political origins of ecological continuity of rivers. We analyse how the construction of the concept and the development and implementation of the policy of the ecological continuity combined science and politics. After providing an analyzis of the history of the concept and the policy, we describe its various translations (European and French) in order to detail the evolution of scientific and political entanglements that have resulted in its application to French territory . The thesis adopts an approach that borrows from discursive analysis to explain different ways to interpret the ecological continuity of rivers through science (knowledge, expertises) and politics (entities , values ).The final part provides a fine-grainedanalysis of how public policy implements the removal or alteration of hydraulic workson rivers so as to realize ecological continuityin two French watersheds.The aim is to better understand the main reasonsof disagreementsand conflicts.Flowing from thecritical analysisof thesedifficulties, wepropose a conceptual tool to tackle main challenges involved implementing of ecological continuity and produce what we describe as a "territorial connectivity of rivers".
