This study presents the determination of physical vulnerability indexes on the region of Barreira do Inferno, Municipality of Parnamirim/RN. The natural vulnerability (NV) and environmental vulnerability (AV) indexes were calculated through weighted statistical analysis of the thematic classes of geomorphology, slope, soils, vegetation, geology, land use and occupation. The thematic variables were evaluated to reduce subjectivity and dimensionality through the Hierarchical Analytical Process and Principal Component Analysis. The results showed the domain of intermediate, high and very high vulnerability classes in 75% and 79.1% of the total area in the VN and VA maps, respectively. The Coastal Vulnerability Index (CVI) to erosion was established based on physical and dynamic variables for three different future climate change scenarios of the Intergovernmental Panel on Climate Change. The IVC in 100% of the coastline is of low vulnerability in the optimistic scenario. In the pessimistic projection, 31% of the shoreline extension is of intermediate vulnerability.
