Second-home owners and sea-level rise: the case of the Languedoc-Roussillon region (France)

Municipalities of the Languedoc-Roussillon region (South-eastern France) are highly vulnerable to climate-change-induced sea-level rise (SLR) due to their low altitude and the great attractiveness of the region for tourism. This attractiveness has resulted in a very significant development of second homes, which represent half of the housing stock and three quarters of the total capacity for tourism hospitality. In the context of climate change adaptation measures related to SLR, it is imperative to consider the perceptions of second-home owners and their place in local governance arrangements. Scientists advocate the implementation of managed retreat policies to reduce vulnerability by reducing the exposure of buildings, but both the social acceptability and the economic feasibility of these policies are very low. We assume that second-home owners have different perceptions of the risk of inundation and are less involved in the governance mechanisms. It is very difficult to mobilise a large number of owners of small flats who are less concerned with, and less likely to contribute to, policy development, due to their less frequent presence. We studied these issues through a survey in three municipalities, based on a sample of 318 residents and 163 second-home owners faced with inundation risk. We observed a lower sensitivity to risk and a stronger attachment to homes on the part of second-home owners (compared to residents). We also discuss, in terms of equity and efficiency, the impact of their low level of engagement in governance mechanisms.

Valuing welfare impacts of climate change in coastal areas: a French case study

Beach protection has become a major issue in reducing coastal risks (erosion and flooding). It is thus advisable to study residents’ preferences for mitigation strategies. Willingness-to-pay (WTP) by permanent and secondary residents for flood protection provided to properties by Languedoc-Roussillon beaches (French Mediterranean coast) is investigated by a contingent valuation study. Results show that WTP is more influenced by risk perception variables than by socio-economic ones. The WTP is then extrapolated on the basis of different adaptation strategies (laissez-faire, managed retreat, denial etc.) which provided information about expected damage associated with sea level rise at the 2100 time horizon.

Eliciting preferences for wetland services: a way to manage conflicting land uses

A choice experiment was used to analyse the preferences of residents neighbouring the Erstein polder (Alsace, France) for the different services that it provides. The heterogeneous nature of these preferences was shown through the use of a latent class model. Whilst the population as a whole values the improvement in water quality and the contribution, even partial, to flood protection, preferences differ when it comes to biodiversity and public access to the site. This study shows the potential conflicts between the different uses of the Erstein polder. These conflicts represent different communication themes for the site managers.

Resistance to relocation in flood-vulnerable coastal areas: a proposed composite index

ABSTRACT The increasing number of coastal floods in recent years in France has resulted in the design of new adaptation principles for the most endangered coastal areas. The aim of the government is to reduce the vulnerability of these areas by relocating property and infrastructure. These measures have, however, come up against considerable opposition from the population concerned. Using a survey of 421 inhabitants of Hyères, a coastal town in the South of France, this article proposes the study of resistance to relocation through the creation of an index for resistance that incorporates attachment to place, residential mobility and risk perception. The results show a correlation for the index and distance from the sea that highlights the existence of conflicting interests with adaptation measures depending upon population categories. Key policy insights In France, although coastal flooding risk is a key issue in numerous populated coastal areas, coastal dwellers show little willingness to relocate. Resistance to relocation can be assessed through a composite index integrating place attachment, residential mobility and risk perception. Application of such an index shows a correlation between willingness to relocate and distance from the sea. Conflicts of interest with adaptation measures also depend on the age of the dwellers, their standard of living and on home ownership.

Impact of justice and solidarity variables on the acceptability of managed realignment

Sea-level rise due to climate change will have significant effects on coastal areas and populations. Adaptation policies recommend the managed realignment of the most vulnerable assets and activities. Despite their medium- and long-term benefits, these policies face significant friction due to social acceptability in the communities where they are implemented. This article investigates the hypothesis that respecting principles of justice in the implementation of managed realignment should increase its acceptability. We compare preferences of those people who are exposed to the risk of climate-change-induced flooding and those who are not, as regards funding managed retreat policies and defining compensation criteria for assets at risk. The main theories of social justice provide the four principles included in the analysis: efficiency, need, responsibility and priority assigned to property rights. A choice experiment survey was conducted with 258 residents of coastal and hinterland communities in the south of France. Four attributes were selected to define the managed realignment policy: the dialogue arrangements, the implementation period, the policy implementation schedule and the cost. The results show support for a relatively fast launch of these policies (within 15 years) but in stages and through a process of dialogue with the population. Peoples perceptions of the funding criteria reveal a preference for national solidarity. Finally, national funding of managed retreat policies and compensation criteria based on market prices have a significant positive influence on the acceptability of managed realignment policies, whereas introducing responsibility-based compensation criteria tends to favour the status quo over the adaptation policy. Policy relevance Prioritization of the funding criteria reveals the preference for national solidarity. Preferences for the justice criteria underpinning compensation reveal a great diversity of values. Besides implantation modalities, preferences for managed realignment policies depend on which level they are implemented at, on the expropriation criteria (the emphasis given to property rights, i.e. market price), on the attachment (people perceived as worst off, i.e. the property is their main residence rather than a second home or they have lower levels of income) and on the degree of responsibility (related to the date of purchase, i.e. on the information given at the time on the risk).
