Climate adaptation in Brazil: Advancements and challenges

We present a systematic review of the scientific production on climate adaptation in Brazil, using quantitative and qualitative methodologies. The analysis of adaptation categories indicated a good balance between social (38 %) and institutional (33 %) adaptation actions, with a lesser share of physical/infrastructure adaptation (25 %). Assessed impacts tend to focus on higher temperature or heat events (21 %), mainly with regard to human health, along with droughts or water resources issues (20 %), particularly agricultural production. The studied biomes or environments showed a predominance of the most populous areas, such as urban (27 %) and coastal (17 %), indicating the need to target climate adaptation actions at the various Brazilian natural biomes, which, together, are addressed in only 30 % of the papers analysed (all six biomes combined). Indexes development and documentary analysis were predominant methodologies. The dialogue between science and society must be improved, especially with public management, in the production, execution and dissemination of climate adaptation actions. Nature-based solutions were listed as emerging solutions for addresing climate change impacts, acting both for mitigation and adaptation. Popular participation was pointed out by several authors as fundamental in the joint construction of these actions, as well as the provision of information on access to climate finance, which may be of interest to both public and the private sectors.
