Subnational REDD+ Initiatives

The Global Comparative Study (GCS) on REDD+ is conducting research at the subnational level in six countries: Brazil, Peru, Cameroon, Tanzania, Indonesia and Vietnam.

The research involves collecting data before and after implementation of REDD+ interventions to measure changes in carbon stocks, human welfare and other relevant outcomes. The research design also involves comparison between villages where REDD+ interventions have been made (intervention sites) and those where they have not been made (control sites).

The research focuses on impact evaluation of the outcomes of REDD+ interventions, but also examination and reflection on the process of setting up and implementing REDD+ projects and programs.


By using our ‘BACI’ (before-after/control-intervention) method, our research aims to provide empirical evidence on what has and has not been successful in REDD+ initiatives with respect to ‘3E+’ outcomes of effectiveness, efficiency, equity, and co-benefits such as livelihoods, governance and biodiversity.


This empirical evidence relates to a number of core research themes. Find out more by following the links below.
