“…The total cost of this work was estimated at €500 per m, plus an annual maintenance allowance equivalent to 2% of the investment (€10 per m, annually). Although this price range is similar to those outlined in other studies [29], it is important to note that these costs vary depending on the initial state of the structure, required elevation increase, and/or availability and proximity of necessary construction materials.…”

Coastal flooding along the Atlantic coast caused by Storm Xynthia killed 41 people. The location and configuration of residential housing were the main factors affecting the vulnerability of people to flooding. The French government responded by destroying buildings in the most flood-prone areas and relocating residents to safer areas. This strategy attracted much criticism, in particular because of the high costs involved with demolition on this scale, and that not insufficient consideration was given to other possible solutions. In this study, the goal is to compare different adaptation strategies in terms of cost of implementation and efficiency in order to reduce the vulnerability of houses to flooding. The strategies are grouped based on: (i) protection, (ii) relocation, (iii) housing architectural adaptation, and (iv) preventive warning and evacuation. This work is applied to La Guérinière, an Atlantic coastal town at risk of coastal flooding, although it was not impacted by Storm Xynthia. The initial results show that the most efficient strategy to reduce housing vulnerability to coastal flooding is also the most expensive. Ranked from the most to the least efficient and expensive, the strategies are as follows: (i) relocation, (ii) housing architectural adaptation, (iii) protection, (iv) and preventive warning and evacuation. Until now, these strategies have been limited as they omit human behaviour in response to coastal flooding scenarios. Therefore, this study examines the role of human behaviour in relation to different mitigative strategies. The efficiency and costs of the strategies are then reappraised.

“…In addition, for specific configurations it provides nursing ground for many species of fish and shellfish, resting places for migratory birds, and natural cleaning of ground and surface waters. Compared to US or UK, depolderisation has rarely been used in France (Goeldner-Gianella et al, 2015). Following the recent marine floods of Xynthia (2010) and Martin (1999), risk management techniques for sea flooding mainly consist of raising or reinforcement of dikes.…”

“…Indeed, climate is undeniably changing and urban planning and policies still play a central role in the fight against climate change ( Eraydin and Taşan-Kok, 2013 ). Even though some authors demonstrated a relationship between the proximity to the coastline and climate change belief ( Milfont et al, 2014 ), these policies and plans are often rejected ( Goeldner-Gianella, 2007 ; Goeldner-Gianella et al, 2015 ) or criticized for their unfairness and perceived injustice ( Jarvie and Friend, 2016 ). Indeed, coastal flooding is usually addressed by building or adapting coastal defense structures or by relocating populations ( Macintosh, 2013 ) and it is necessary to develop a more adaptive and proactive management ( Torabi et al, 2018 ).…”

“…In this perspective, it is necessary to take into account the psychological mechanisms underlying the shift from risk perception to the implementation of coping strategies among non-experts. It is a necessary step to overcome citizen rejection of actual risk management policies and to promote adapted risk management plans ( Goeldner-Gianella, 2007 ; Goeldner-Gianella et al, 2015 ; González-Riancho et al, 2015 ).…”

Impact of Place Identity, Self-Efficacy and Anxiety State on the Relationship Between Coastal Flooding Risk Perception and the Willingness to Cope

Inhabitants of coastal areas are constantly confronted with minor or major events such as storms, erosion or flooding. This article investigates the predictors of coping willingness among citizens exposed to coastal flooding. Coping can be defined as a set of cognitive and behavioral efforts to master, reduce or tolerate a given risk and these strategies are generally regrouped into two different categories: active coping strategies oriented toward the risk to reduce or master it, and passive coping strategies focused on the reduction of internal tensions such as anxiety or fear. In this paper, we focus especially on how place identity, perceived self-efficacy, anxiety-state and coastal flooding risk perception shape both active and passive coping willingness. Data were obtained from different areas at risk of coastal flooding located in France. The sample is composed of 315 adult participants (mean age = 47; SD = 15). Two competing models were tested using path modeling. We expected a direct relation between risk perception and the willingness to cope actively and that a higher perceived self-efficacy would increase active coping willingness. Concerning passive coping strategies, we expected that a higher anxiety-state increases passive coping willingness, and that place identity would act as a mediator and increases the relation between anxiety-state and passive coping willingness. Results suggest that place identity increased when the living place is threatened and that the use of passive coping strategies also increased. Also, we demonstrated a direct relation between risk perception and active coping willingness but it appeared that self-efficacy has no effect on this relation. Model fit indices suggest the good fit of our model and Bayesian model comparison reveals a very strong evidence of the best fit of this model compared to its saturated and independent equivalents.
