In the context of a climate emergency, cities are vulnerable territories prone to several disaster risks of different nature. Latin American cities are especially vulnerable, with high rates of urbanization and severe socio-environmental problems. Within this scenario, this paper aims at addressing strategies for disaster risk reduction (DRR) with emphasis on those risks potentially intensified by climatic changes, focusing on the Brazilian urban space. To look at these linkages contextually, a case study was carried out. This comprises the case of a drainage basin located in an urban area in Brazil (the city of Florianópolis, State of Santa Catarina). Drawing on the case study, the paper examines the existing interaction between sectoral policies for urban land use, climate change and DRR by analysing a set of international documents and Brazilian domestic law and policy frameworks selected at all governance levels (national, state, and municipal). Furthermore, it explores the availability and accessibility of official data related to the area under study in terms of disasters events, climate risks, demography of the affected populations and environmentally protected areas. Finally, it sheds light on the role of cartography, in particular of risk maps, in the coordination of land use rules and DRR policies.
