Changes in climate conditions and the increasing number of climate-related disasters are modifying mobility patterns in Brazil. The multi-causality of factors leading to migration hinders not only the identification of such individuals but also the development of solutions. This study aims to analyse to what extent Brazil’s national climate and migration policies are aligned with international recommendations by identifying synergies and other specific provisions associated with human mobility in the context of climate change. It initially focuses on how rising global average temperatures relate to human displacement nationwide.
