“Cash for Carbon: A Randomized Controlled Trial of Payments for Ecosystem Services to Reduce Deforestation”
Abstract: This paper evaluates a Payments for Ecosystem Services (PES) program in western Uganda that offered forest-owning households cash payments if they conserved their forest. The program was implemented as a randomized trial in 121 villages, 60 of which received the program for two years. The PES program reduced deforestation and forest degradation: Tree cover, measured using high-resolution satellite imagery, declined by 2% to 5% in treatment villages compared to 7% to 10% in control villages during the study period. We find no evidence of shifting of tree-cutting to nearby land. We also use the estimated effect size and the “social cost of carbon” to value the delayed CO2 emissions, and compare this benefit to the program’s cost.
