Mangroves play an vital role in the marine carbon cycle and are therefore referred to as ‘blue carbon ecosystems’

Blue carbon ecosystems include mangroves, seagrasses and tidal marshes, and are so named because of the twin characteristics of being essentially marine and containing disproportionately high quantities of organic carbon.

Blue Carbon ecosystems play a vital role by supporting food security and livelihoods, especially by supporting fisheries and tourism. They can also play an important role in climate change mitigation and adaptation  and there is potential for communities to access carbon finance to enable local protection and restoration efforts. However, when degraded they can become significant sources of greenhouse gases.
