Reducing Emissions from Deforestation and Forest Degradation and enhancement of forest carbon stocks (REDD+) is enshrined in the Paris Agreement and has been adopted by many countries as a way to promote climate and development benefits from forests. After more than ten years of experimentation, the novel feature of REDD+ – the prospect of offering large-scale, results-based finance to developing countries as a reward for performance – is beginning to materialize. CIFOR and partners have been implementing a Global Comparative Study on REDD+ (GCS REDD+) since 2009. Through research and engagement at international, national, subnational and local levels, we ensure that policymakers and practitioner communities have access to – and use – the information, analyses and tools needed to design and implement effective, efficient, and equitable REDD+ policies and actions. This webinar highlighted research done under GCS REDD+, which can support subnational REDD+ implementation in Brazil, and discussed ways to strengthen the connection between science and public policymaking.
