| Abstract | ||
| Mangrove ecosystems are significant carbon sinks and play a vital role in climate change mitigation. This study quantified carbon stock and sequestration potential in mangrove stands on two small islands—Akat Island and Parang Island—in East Seram Regency, Maluku Province. Field data were collected using the quadrat transect method to measure tree density and diameter, with biomass estimated through species-specific allometric equations. Results showed that Akat Island had the highest total carbon stock (255.75 Mg C/ha), primarily contributed by Sonneratia alba and Rhizophora stylosa. Parang Island recorded a carbon stock of 219.85 Mg C/ha but exhibited greater species diversity. The estimated carbon sequestration potential, expressed as CO₂ equivalent, was 518.14 Mg CO₂e/ha for Akat Island and 439.04 Mg CO₂e/ha for Parang Island. These variations likely reflect differences in ecological conditions, stand structure, and anthropogenic pressures. The findings underscore the strategic role of small-island mangroves as nature-based climate solutions, with strong potential for integration into green economy mechanisms such as carbon trading and REDD+ programs. This study is among the first to provide empirical estimates of mangrove carbon stock in Maluku’s small islands, helping fill a critical data gap to inform conservation policy and sustainable coastal management. | ||
