This report presents the results of a study carried out to assess the carbon pools, ecosystem services and multiple benefits of the mangroves in the Central African countries of Cameroon, Gabon, Republic of Congo (RoC) and Democratic Republic of Congo (DRC). Mangroves are among the most carbon-rich ecosystems in the world, and also provide valuable ecosystem goods and services such as fisheries production, shoreline stabilization, nutrient and sediment trapping as well as biodiversity habitats. Their high carbon storage and sequestration potential, and the high value of the multiple benefits they provide make them important coastal forest ecosystems to consider including in national REDD+ strategies. This is the first study on carbon stocks, sequestration rates and possible emissions resulting from degradation that has been undertaken for mangroves of the Central African region. The study also includes remote sensing results on changing mangrove cover, and a valuation of ecosystem services that local communities gain from the mangroves.
