The “carbon sink” service is one of the numerous important benefits blue carbon ecosystems provide to human well-being, along with food security, water quality improvement, raw materials and shoreline protection among others. When degraded, co-benefits provided by mangroves are greatly diminished along with the ecosystems’ capacity to sequester carbon. Restoration and protection of mangroves is, therefore, recognized as a priority for both climate change mitigation and adaptation; and several countries have identified measures that harness these benefits in their National Determined Contribution to Paris Agreement.
