Strategies for adapting to hazards and environmental inequalities in coastal urban areas: what kind of resilience for these territories?

Abstract. The ongoing phenomenon of climate change is leading to an upsurge in the number extreme events. Territories must adapt these modifications order protect their populations and properties present coastal areas. adaptation areas also aims make them more resilient future In this article, we examine two strategies for adapting risks: holding line through hard constructions such as seawalls or ripraps managed retreat activities a part territory not exposed hazards. France, approaches are financed by solidarity insurance system at national level well local taxes. These systems aim compensate affected finance implementation chosen authorities. However, French mainland coast generally attracts affluent residents, price land being higher than inland. This situation induces presence inequalities territories, which can be maintained reinforced short medium term when defense strategy based on implemented. trajectory, it appears that territories would less long because maintenance costs structures uncertainties relating hazards (submersion, rising sea levels, erosion). Conversely, with managed-retreat strategy, instead done away since property no longer hazards, cost society lead towards greater resilience term. Only one social group strongly impacted they subjected another territory.
