Segurança hídrica e mudanças climáticas no Brasil

Abstract

Extreme climatic events in Brazil recently warn to the need for measures to ensure water security in the country. Such events may intensify as a result of the impacts of climate change. This paper proposes to carry out an assessment of the water security situation in Brazil taking into account these possible impacts. In general terms, we present a diagnosis of the theme, a prognosis of the theme, the situation of the research on the theme and the major political-institutional frameworks. The main research challenges are the uncertainties of climate models and deficiencies of hydrological models to simulate land use changes. Significant progress has been made in the legal framework currently in Brazil regarding mitigation and adaptation of climate change in the various sectors involved. However, there is still a need to improve the dialogue between academia and decision makers.
