data consultation service (WMS) from: Vulnerability of the national territory to coastal risks — Reunion

This study, led by CETMEF and carried out in collaboration with the Mediterranean and Western CETE, provides a national synthesis of current knowledge on coastal risks (erosion of low-furnished coasts and cliffs, dune advances, marine submersion) and establishes a simple mapping of the areas currently vulnerable to coastal risks in Guadeloupe. The study is thus divided into two parts: a bibliographic synthesis on the one hand and the definition of methods for quantifying vulnerability on the basis of cartographic indicators on the other. The indicators produced in the study are: — the level of knowledge of coastal risks, — low areas, — orders recognising the state of natural disaster (CAT-NAT) linked to the sea, — atlases of flood zones and prevention plans related to the sea, — the stakes in low areas, — the cross-indicator IBC representing the degree of intensity of the building in the municipalities located in low areas which have been the subject of a decree of natural disaster linked to the sea, — the cross indicator IB representing the degree of intensity of the building in the municipalities located in low areas. These indicators are now available for visualisation except for the indicators “level of knowledge of coastal risks” and “at stakes in low areas”, which have limited value for dynamic visualisation.
