In an interdisciplinary research (ethnology, geography, geology, psychology…), this study explores the management of coastal risks in relation to the evolutions of the coastline and their consequences in terms of erosion and flood. A multitude of stakeholders are involved in the coastal risk, either by their role in the management of coastal areas (state, local authorities…), or by the use of these areas (inhabitants...). Even if risks can be localized and defined by experts(e.g., in preventive maps of risks), stakeholders can have a different perception of them because they have not necessary the same reference framework to construct their representation of the risk. We postulate that risk is a social construction based on social representations (SR), historically and culturally determined. Thus, it seems important to analyse the SR related to coastal risks, and more widely the relationship between these stakeholders and their environment, for understanding the norms, beliefs, values and actual practices of these groups, in the management and the use of the coast. These SR depend on a diversity of factors (contextual, cultural, temporal…) and they constitute a particular relation to environment which informs us on intergroup relationships.To analyse these SR and the relationship between stakeholders and their environment, we are going to lead a survey (interviews and questionnaires) among managers and users concerned by the littoral (inhabitants, professionals, local authorities…). Our communication will introduce the results stemming from the first stage. Semi-structured interviews were led in Brittany (France) in littoral towns, on three main subjects: (1) the evaluation of their habitation/town and its surrounding, (2) the concept of risk in general, risks in the town, and the coastal risks, (3) events associated with storms (for the individual / for the town).Furthermore, we made an analysis of articles published in the local medias on the themes of erosion, floods, storms. The interviews and the articles were analysed by a computer-aided analysis, with the Alceste software. This exploratory analysis was supported by a manual analysis of thematic content.In the medias, the first results highlight a content based on a description of events and historical accounts related to sea and to storms. There are also a lot of articles in relation to climate change and global warming. Another category focuses on action and prevention plans linked to risks. This category also appears in interviewees’ discourse, but it more focuses on actors responsible for risk management. Otherwise, events imbued with personal experiences (of storms, floods…) are recounted. Finally the impact on business activities, fishing for example, is also discussed. In all these analysis, the temporal dimension is particularly important. The importance of these different themes and their implication for the stakeholders will be discussed in the communication.
