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