Eleventh International Conference on Climate Change: Impacts & Responses

Abstract

Half of the human population lives in cities and most of it is in the coastal strip. Brazil is no exception to this rule: more than 60% of the population lives in coastal cities. Current climate changes expose coastal cities to rising sea levels, changes in the frequency and intensity of storms, and increased precipitation and ocean temperatures. Each of these factors poses risks to the human population. Increasing the frequency and intensity of extreme rainfall events increases the risk of landslides, floods and floods. Rising sea levels may increase exposure to housing and infrastructure risks, such as schools, markets, hospitals, ports and highways, flooding and erosion in coastal areas. Also, the trend of more intense storms can increase the risk of populations in coastal cities to events such as floods, landslides and coastal flooding. In this context, Brazilian coastal cities demand investments and adaptation measures in the face of climate change, with a focus on reducing risks and minimizing the impacts caused by extreme climatic and oceanographic events observed in the present and projected for the future
