ECOSYSTEM-BASED DISASTER RISK REDUCTION SERVICES OF MANGROVE FOREST
Mangroves reduced the impact of catastrophic events through their functions, such as carbon sequestration and protection against upland flooding. Understanding the Ecosystem-based Disaster Risk Reduction (Eco-DRR) services provided by mangroves is essential for their conservation and protection. This study highlights a range of figures that illustrate the Disaster Risk Reduction (DRR) capacities of mangroves, with a specific focus on the hazards associated with climate change. There were 430 trees across six true mangrove species assessed in the Sukol River. The total estimated biomass of these mangroves was 5,905.88 Mg•Ha-1, AGB and BGB combined. The amount of their biomass resulted to 2,775.76 Mg•Ha-1 of carbon stock (equivalent to 10,187.05 Mg•Ha-1 of carbon dioxide). Meanwhile, the studied ecosystem reduced the velocity of flowing water under normal condition by 0.57 m/s, impacting the rate of discharge of the river to 190.12 m3/s, resulting in a flow rate of 2691.64 cfs. The presence of mangroves along the coastal areas serves as a vital ecological asset, offering Eco-DRR services in terms of carbon sequestration that lessen the impact of greenhouse effect in the climate condition of earth. Moreover, their rigidity and complex physiological features made them effective in buffering the impact of flooding.
