Mangroves provide multiple ecosystem services such as blue carbon sequestration, storm protection, and unique habitat for species. Despite these services, mangroves are being lost at rapid rates around the world. Using the best available biophysical and socio-economic data, the authors present the first rigorous large-scale evaluation of the effectiveness of protected areas at conserving mangroves and reducing blue carbon emissions in the journal Ecological Economics. The analysis examines the success of protected areas in Indonesia between 2000 and 2010, finding that their use has avoided the loss of 14,000 hectares of mangrove habitat and approximately 13 million metric tons (carbon dioxide equivelent) of blue carbon emissions.
