The U.S. Agency for International Development (USAID) Low Emissions Asian Development (LEAD) program and U.S. Forest Service have developed a guide to support field training on carbon accounting of mangroves and other forested wetlands in Asia. The annotated field guide aims to help trainers, researchers, and government officials in Asia apply the Protocols for the Measurement, Monitoring and Reporting of Structure, Biomass and Carbon Stocks in Mangrove Forests, a commonly used protocol for carbon accounting of mangroves and other forested wetlands developed by the USAID Sustainable Wetlands Adaptation and Mitigation Program (SWAMP) program, a collaborative effort by the Center for International Forestry Research (CIFOR), U.S. Forest Service, and Oregon State University, with support from USAID.
