In this study, we applied a methodological approachto assess the value of shoreline protection servicesprovided by mangroves. Our approach involvedusing global flood risk models to simulate the impactof waves and surge generated by tropical storms asthey interacted with mangrove shorelines. Throughthis modeling, we evaluated the socioeconomic riskassociated with flooding and quantified the floodprotection service offered by mangroves. To capturetemporal dynamics, we used mangrove extent layersfrom multiple time points, spanning the periodfrom 1996-2020. By incorporating these temporaldimensions, we were able to measure how theasset value of mangroves changed over time, thusproviding insights into the evolving importance ofmangroves for shoreline protection.
