, 3D views of twenty-one (21) municipalities color coded by their degree of risk to catastrophic natural hazards owing to climate change. The Total Vulnerability Index (TVI) encompasses, within a single index, eighteen (18) parameters within three (3) governing sub-systems (administrative and legal; physical and natural; socio-economic) of the municipalities. The municipalities of Paimpol and Saint-Brieuc are at most risk as revealed by the TVI. Thirteen (13) municipalities demonstrates low TVI despite high vulnerabilities for certain sub-systems, Also shown are the combination of Coastal Vulnerability Index (CVI) and Administrative Vulnerability Index (AVI), and Coastal Vulnerability Index (CVI) and Socio-Economic Vulnerability Index (SVI)
