Post-doctoral position – incentives for residential mobility in high-risk residential coastal areas.
The coastline is exposed to significant and increasing risks of erosion and flooding (IPCC). Yet it remains very attractive for many populations, leading to upward pressure on land and real estate markets; social and environmental inequalities are growing. The growing vulnerability of these territories to risks requires the implementation of adaptation strategies at the territorial level. The national integrated coastal management strategy
(NICMS) is being revised for the period 2025 – 2030 (currently in consultation). The evolution of climate is accompanied by an increase in insurance claims in these territories. The French natural disaster surcharge has increased on January 1, 2025 (from 12% to 20%) to correct the imbalance of the natural disaster compensation scheme in the short term, but its resilience to climate change in the medium term requires working on other levers. It is thus advisable to encourage the adoption of individual protective behaviours, which the CatNat mechanism is struggling to induce (when CatNat is applicable).
This study adopts this perspective, and more particularly targets incentives to change individual behaviors.
We propose to address this issue and to design, and test with the inhabitants of coastal areas, prototypes of incentive schemes. The possibility of a new insurance contract alone does not seem sufficient, but it could be studied as part of a more complex scheme combining financial incentives via insurance with non-monetary incentives.
