La résilience des territoires littoraux face au risque de submersion marine. Application sur les territoires de la Charente-Maritime et de la Somme

Abstract : From a vulnerability study, the thesis proposes to experiment and compare the resiliency of two territories exposed to marine flooding, the Charente-Maritime and the Somme. Resiliency refers to the capacity to anticipate, react and recover from a disturbing event. The aim consists in developing the concept of resiliency. Then, the factors and mechanisms of resiliency are studied, with territorial actors (actors on the ground, professional and institutional organizations) who play a role in the dynamics of the territory. We seek to delineate spatial resiliency (beyond the impacted territory?) and temporal resiliency (before, during and after a disaster?). The method is based on interviews allowing to highlight the capacities and capabilities of resiliency (semantic exercise), and the temporal limits through a graphic representation named “resiliogram”. The second exercise is based on the identification of spatial resiliency, with mental maps which bring to light the representation and the knowledge of areas exposed to marine flooding. From the linking of these diverse modes of data collection, a Global Resiliency Index (GRI) is created and allows the creation of different resiliency profiles. Ultimately, this work helps the territorial actors to better anticipate a potential disaster and helps the institutional organizations to adapt their management, their speech to the realities of the ground.
