Community Monitoring of Carbon Stocks for REDD+: Does Accuracy and Cost Change over Time?
This report goes beyond static one-off assessments of biomass to examine trends in accuracy and costs of local forest monitoring over time. It analyses repeated measurements by community members and professional foresters of 289 plots over two years in four countries in Southeast Asia. The results show that as measurements are repeated, community members’ biomass measurements become increasingly accurate and costs decline. These findings support existing evidence that community members can play a strong role in monitoring forest biomass in implementation of REDD+ at local level.
