Ecosystem-based coastal protection offers a strategic approach to mitigating the impacts of climate change, particularly in small island contexts. This study integrates remote sensing and geospatial analysis to estimate blue carbon stocks in the mangrove ecosystems of Dompak Island, Tanjungpinang, using Google Earth Engine (GEE) and Sentinel-2 satellite imagery. Through the application of the Normalized Difference Vegetation Index (NDVI) and an empirical model for Above Ground Biomass (AGB), spatial carbon stock distributions were generated and classified into three functional zones: conservation, restoration, and critical protection. Results reveal that areas with moderate vegetation exhibit the highest carbon stock (32.00 tons/ha), suggesting ongoing biomass accumulation. This spatial analysis informs a zoning framework that supports ecosystem-based infrastructure planning. The integration of carbon mapping with adaptive civil engineering strategies demonstrates a scalable model for climate-resilient coastal development in vulnerable regions.

Conclusion

This study successfully integrated remote sensing and geospatial analysis to estimate blue carbon stock and inform coastal protection planning.By utilizing Sentinel-2 imagery and NDVI in the Google Earth Engine (GEE) platform, mangrove distribution and carbon stock were quantified in Dompak Island.The resulting data enabled the classification of coastal segments into conservation, restoration, and critical protection zones, each accompanied by tailored engineering strategies, providing a replicable model for sustainable coastal infrastructure planning.

Future Research

Future research should focus on validating the satellite-based carbon stock estimates with ground-truth measurements to improve accuracy and contextual relevance. Expanding the study to incorporate hydrodynamic modeling and higher-resolution imagery will allow for a more detailed understanding of coastal processes and inform more robust engineering designs. Furthermore, investigating the socio-economic benefits of mangrove conservation and restoration, including the role of local communities in sustainable management, is crucial for ensuring long-term success and fostering a holistic approach to coastal resilience. These investigations will contribute to a more comprehensive understanding of mangrove ecosystems and their potential for mitigating climate change impacts while supporting sustainable coastal development, ultimately leading to more effective and equitable conservation strategies.
