The effects of climate change on coastal risk factors are increasing due to both rising sea levels and increasingly intense coastal floodings. However, these changes are only just beginning to be incorporated into planning strategies for coastal economies and land use in France. Recent coastal storms marked the turning point, and public authorities have now started to revise coastal management legislation, stating that the managed retreat of settlements and infrastructure is the preferred strategy to adapt to climate change. To date, this managed retreat has almost exclusively been discussed in relation to the current political, social, and economic obstacles that make it difficult to relocate equipment and houses inland. Here, we add to this discussion by depicting how the careful ecological restoration of dunes and salt marshes on land made available by managed retreat could overcome some of these obstacles. First, we describe three possible strategies to adapt to sea-level rise as well as the maladaptation of the current strategy. Then, we focus on the limitations and advantages of ecological restoration in terms of managed retreat and vice versa. Finally, we depict how a new kind of land lease, introduced in draft legislation, can help tackle the multitemporal and multispatial issues that currently hinder managed retreat.
