Abstract
Vulnerability to Sea Level Rise in the Metropolitan Region of Rio de Janeiro Through 3D Modeling

Research conducted by Pereira Passos Institute (Rio de Janeiro´s City Hall cartography, statistics and information institute) identified the most social and environmental vulnerable areas to the sea level rise due to climate change in the Rio de Janeiro´s Metropolitan Region, Brazil. In order to do so three sea level rise scenarios were mapped (0.5, 1.0 and 1.5 meter), in accordance to the latest IPCC report and other science publications. Geoprocessing tools from the ArcGIS software were used to generate a Digital Terrain Model (DTM) from the cartographic datasets available for the area, such as contours, spot elevations and coast line. Quality control was conducted for the DTM generated and the source datasets and after approval the following step was to map the areas which elevation were under the three selected scenarios. The results obtained show that three regions stand out from the others as more vulnerable and these are: the coastline from the Sepetiba Bay, in the western zone of Rio de Janeiro City; the lowlands and lagoon system of Jacarepaguá, also in Rio de Janeiro and an important region for the Rio 2016 Olympic Games; and the Environmental Protection Area of Guapimirim, dominated by mangroves in the cities of Guapimirim, Magé and São Gonçalo. The most critical case can be considered the Jacarepaguá Lowlands, where the lagoon system of the same name can have its water mirror expanded to several occupied areas around its margins, like the neighborhood of Itanhangá and the Rio das Pedras slum. This research allows the City Hall of Rio de Janeiro and the other cities of its Metropolitan Region to plan strategies of climate change adaptation and other city resilience initiatives, besides the greenhouse gases emissions mitigation actions that Rio de Janeiro is already implementing.
