Résumé

Abstract Studying the population's perception of coastal erosion is essential and is increasingly used by coastal administrators, especially because it strongly influences the acceptance of coastal adaptation strategies. This article explores the population’s perception of coastal risk on the atlantic coast of France (pays de la Loire region) that is an at-risk territory historically affected by erosion and particularly sensitive to coastal flooding. The major goal of the paper is to collect data in terms of risk perception by carrying out a field survey on three territorial collectivities, with the aim to enhance the feasibility of the managed retreat operations that will be implemented on this coast in the next years. A total of 700 surveys were collected and several original results can be drawn: the population has a good knowledge of erosion in the area where they live and this knowledge is key as the territory is vulnerable. Similarly, the respondents have a good knowledge of protection measures but some are more important than others: for example, the reinforcement of coastal defenses is the most commonly cited strategy to deal with coastal hazards while relocation is the second most known but least popular scenario. Finally, several factors influence people's perception of risk: for example, time spent in the residence and age of residents are two elements contributing to place attachment which must be taken into account before starting to implement any climate adaptation policies.
