Coastal flood risk: improving operational response, a case study on the municipality of Leucate, Languedoc, France

Abstract

Background: Climate change and rising sea level will certainly lead to significant changes in the management of low-lying coastal areas in the coming decades. While the most recent studies in the field of coastal storms-related flooding are increasingly integrated, simultaneously addressing hazards and vulnerability, as well as population risk perception, there is still little work to consider the preparedness of stakeholders to manage crises whose frequency and intensity are likely to increase in the next years. Methods: The aim of this paper is to expose the major results of the CRISSIS research program, which proposed a multidisciplinary approach to the management of coastal flood risk in a town particularly exposed on the French Mediterranean coast. The originality of the project was to offer both an integrated approach to risk by analysing its 3 dimensions (hazard, impact and vulnerability, and representations and perceptions held by populations and stakeholders, or « risk culture ») and a very operational section focused on the evaluation of crisis management measures led by local stakeholders. To achieve this objective, two crisis exercises were organized, the first one to test the assimilation by the municipality staff of existing crisis management procedures and the second to allow local actors to integrate in their crisis management procedures the new risk knowledge data issued from research conducted under the program. Results: The project has had three main features; (i) it accurately mapped the submersible areas that present a critical vulnerability, both material and human; (ii) it revelated the poor social representation of marine submersion risk, as well as the obvious lack of awareness of crisis management systems and tools and the behavior to adopt in the event of flooding; (iii) Finally, it highlighted the need, through the crisis exercises, for a better assimilation by the municipality staff of the crisis management procedures defined in the Municipal Rescue Plan. Conclusion: The CRISSIS project has demonstrated the usefulness of an integrated and operational approach of coastal flood risk, not only in terms of studying hazards, stakes and vulnerability, but also in terms of crisis management, in particular through the organisation of crisis simulation exercises.

“…From the disaster management perspective, the unpredictability of human behaviour and the prediction of hazards accompanying disasters are also key problems. The first problem can be solved by informing about current warning mechanisms and providing accurate and timely information to citizens (Durand et al, 2018;Tuladhar et al, 2015). In case of a natural disaster, citizens can be informed in three phases: before, during, and after the event (Hua et al, 2013).…”

“…The situation and accessibility of infrastructure, accessibility of health care, human and social capital, and other institutional resources all contribute to the promptness and efficacy of adaptive ability (Paz-Alberto et al, 2021). The CRISIS (Characterizing Submersion Risks in Sensitive Sites) project has demonstrated the usefulness of an integrated and operational approach to coastal flood risk, not only in terms of studying hazards, stakes, and vulnerability but also in terms of crisis management, through the organization of crisis simulation exercises (Durand et al, 2018). LGUs had designated evacuation centers, but there were no security posts, signs leading to evacuation areas, temporary shelters for livestock, and evacuation centers for prisoners.…”

Coastal inconsistencies: Living with and anticipating coastal flood risks in southern France

“…Studies have demonstrated that along the French Atlantic (Michel-Guillou, Lalanne, & Krien, 2015;Michel-Guillou & Meur-Ferec, 2017) and Mediterranean (Durand et al, 2018) coasts local inhabitants are aware of their exposure to coastal flooding yet unworried by the risk (Meur-Ferec & Guillou, 2020;Michel-Guillou et al, 2016;Michel-Guillou et al, 2015). This has been described, from a strictly informational perspective, as a "poor risk culture" (Durand et al, 2018. p. 10).…”
