Mapping Risk and Vulnerability in São Paulo Metropolitan Region

Abstract

Current climate change projections indicate that heavy rainfall is an increasing problem in many areas around the world, including the São Paulo Metropolitan Region, Brazil. This will result in severe flooding and landslides in the upcoming years. Therefore the geography of climate change vulnerability is vital to adaptation planning. Using Geographic Information System (GIS) and mapping tools such as digital elevation models (DEM), this paper identifies the main areas affected by floods and landslides. We characterize such areas by their biophysical dimensions and socioeconomic status. In turn, we not only focus on the physical environment, but examine the geography of socio-political determinants of vulnerability. Overall, this paper will highlight which areas are vulnerable to climate change and what we can expect in 2030.
