This report seeks to further the body of disaster risk management (DRM) knowledge in Santa Catarina by identifying flood asset exposure risks and consequently empower the state government and its institutions to include DRM practices and information in their daily operations and decision-making processes, respectively. In this context, a novel study was jointly designed and developed by the World Bank and Santa Catarina’s state government with the ultimate aim to produce a state-level Catastrophe (CAT) model.
