2. Climate Change Adaptation and
Mitigation with Mangrove Ecosystems
Beyond Green Carbon: The 3rd International Symposium
29 April 2024 | CIFOR-ICRAF Headquarters, Bogor, Indonesia
Background
Mangroves, which are distinct forests in coastal and
estuarine saline wetlands of tropical and subtropical
regions, are pivotal in addressing the climate crisis.
Comprising various species, these ecosyst ems are
categorized into ‘exclusive’ (true mangroves) and ‘non-
exclusive’ (semi-mangroves or mangrove associates).
True mangroves excel in saline environments, with
specialized adaptations like aerial roots for oxygen

Key messages
• Conservation gain more carbon stock than rehabilitation. However, development
such as diverse species mangrove planting should be considered
• Degraded mangrove in storing carbon could be enhanced by permeable barrier.
However, mangrove rehabilitation provide more sustain solution
Conservation over rehabilitation!
