One of the challenges in Climate Change is improving adaptive capacity to environmental change and developing resilience in response to natural disasters. Brazil is the largest country in South America and the fifth largest in the world, with 191 M people (IBGE 2010). Due to its generous biodiversity, Brazil is considered a hotspot for ecosystems conservation. Nevertheless, socioeconomic inequity, urbanization development patterns in areas of flood risk and demographic changes can exacerbate social and economic damages. Part of the problems related to the flooding risks in Brazil is also related to social inequality and inadequate or inefficient urban settlements and urban planning. Furthermore, guiding of a better understanding of how people perceive and face the risks to which they are placed can help coping and adapting to those risks, as well as developing resilience. Sassen (2010: 75, 80) mention that the complexity of cities is part of the problem as well as part of the solution, because some of the damages, vulnerabilities and risks related to climate change and floods are constructed by the own dynamic of the city. All these elements are key factors for social and ecosystem resilience construction. The main objective of the proposed survey of risk perception is to stimulate multidisciplinary research and bring resilience by bringing this research theme in the forefront of the social-scientific discourse. We interviewed circa 1300 people at flood risk areas in costal São Paulo and Rio de Janeiro, Brazil, during 2011-2013. The area selection and analysis was based on Census units and Ponderation areas, to identify vulnerabilities in different scales. Population risk perception of flooding, actions taken and resilience patterns were detected in the survey. Results from this survey work may help to identify gaps and build knowledge bridges that can help to further societal change.
