Understanding what works in forest-based climate change mitigation
3 likes2,009 views
The document discusses the importance of forests in climate change mitigation and the need for effective evaluation of forest-based initiatives such as REDD+. It highlights the modest positive outcomes of local REDD+ initiatives and the challenges in measuring their impacts, including the need for better evidence and evaluation methods. The emphasis is on the call for improved scientific approaches to impact evaluations in forest conservation strategies.

IMPACT EVALUATION OF LOCAL REDD+ INITIATIVES Comparison (Control) REDD+ site (Intervention) Before After IMPACT Intervention After Control After Intervention Before Control Before • 6 countries • 22 initiatives • 150 villages • 4,000 households CIFOR’s Global Comparative Study on REDD+: www.cifor.org/gcs

SOCIAL & OTHER ENVIRONMENTAL OUTCOMES • Well-being effects small, with mixed sign, but more likely to be positive when incentive components included • Land tenure highlighted as persistent challenge • Studies on biodiversity and adaptation outcomes scarce Duchelle et al. 2018, Sunderlin et al. 2018.
