Between 1991 and 2012, almost 39,000 natural disasters were registered in Brazil, affecting approximately 127 million people and causing losses of R$ 182,7 billion. 84% of these disasters are associated with excess and lack of water. In addition to compiling an overview of the human damages caused by natural disasters in Brazil related to excess and lack of water, the present study proposes a regionalization based on the concept of susceptibility to drought and flood, in order to provide an indicative of prioritization of investment in Brazil in the area of risk management. The results of this study are based on the 2013/16 series, since the Brazilian Atlas of Natural Disasters provides data until 2012. Only drought affected 66.1 million people in the period 2013/16. Considering only droughts and floods, the most striking disasters in Brazil, four 'Brazils' coexist in the national territory, being predominantly 'Brazil immune to drought and flood' (46% of municipalities), followed by 'drough Brazil' (29% of the municipalities), 'flood Brazil' (13% of municipalities) and 'Brazil of simultaneous droughts and floods' (12%). In order to improve the National Civil Protection and Defense Policy, it is suggested that the regionalization defined in this study be used as a tool to prioritize investments.
