Troubled waters: Riparian ecosystem services and community opposition to the largest dam removal project in Europe, Vezins Dam, France

The largest Dam removal project in Europe occurred in 2019 with removal of the Vezins Dam on the Sélune River in Normandy, France. The French State ordered removal of the 36-m high Vezins Dam and the 16-m high la Roche-qui-Boit Dam along the Sélune River to restore ecological and longitudinal connectivity to improve riparian water quality, and especially to restore migratory species of Atlantic salmon (Salmo salar) and eel (Anguilla anguilla). We examine community opposition to removal of the Vezins Dam through the lens of riparian ecosystem services and stakeholder values. Primary data sources includes fieldwork, interviews, and an online survey of local stakeholders. Text analysis and interview coding occurred with ATLAS.ti 22, and highlight themes related to federal-local communication and riparian ecosystem services. The French State ineffectively communicated with local communities regarding dam removal benefits and riparian stakeholder values. While the state focused on biophysical ecosystem services, experiential ecosystem services, such as place attachment, were more important to riparian stakeholders. Often portrayed as a positive benefit, here dam removal lacked community support. Failure of government authorities to effectively incorporate stakeholder values along a continuum of ecosystem services substantially compromises future large-scale federal environmental management projects dependent upon local community support. By examining how local actors experienced dam removal, study results increase understanding of environmental governance and the local consequences of national policy decisions, of use in future dam removal projects – including for large dams – in France and internationally.
