Carbon Burial and Land Building in Low-Laying Tropical Coastal Wetlands
A new way to integrate climate mitigation and adaptation strategies

Mangrove forests play dual roles, mitigating as well as adapting to climate change. Even when they are degraded, the carbon burial is maintained at almost half a ton per hectare every year. Depending on the hydro-geomorphic settings the range of sedimentation rate between 2.3 – 11.6 mm yr-1 is sufficient to cope with the IPCC high scenario (RCP 8.5) of sea level rise of 7 mm yr-1. This is an adaptation capacity of coastal ecosystem that has been underestimated. Mangroves have the tickets to enter the Paris Agreement as the Nationally Determined Contributions (NDC) encourages the bundling of adaptation and mitigation measures. Likewise, the Reduced Emissions from Deforestation and forest Degradation (REDD+) mechanism and Joint Mitigation and Adaptation (JMA) actions may be implemented by including both degraded and conserved mangroves.
