The Ecosystem-based Disaster Risk Reduction (Eco-DRR) Framework focuses on managing, restoring, and conserving the environment for the purpose of integration in the Disaster Risk Reduction (DRR) program. The leaders and managers around the world utilized the intrinsic services provided by the ecosystem as reinforcement to reduce the impact of disaster brought by natural hazards. However, in spite of their significance in superseding disastrous natural events and policies protecting them, anthropogenic activities continually exploit the resources of the environment for development. This turns out that the challenge of this approach in DRR program is the insufficiency of techniques to measure and describe the intervention done by a specific ecosystem to reduce the damage of natural hazards and for humans to realize its importance. In this case, the study formulated an assessment tool to measure the value of one of the most exploited biomes globally, the mangrove ecosystem. The assessment tool concentrated on the DRR services of the studied ecosystem using two (2) types of approaches: a) the Ecological Assessment; and, b) Social (Community) Assessment. These approaches contain different parameters to be used as DRR evaluation instrument and their implementations are guided by the proposed assessment framework for Eco-DRR. This framework serves as a guide in the selection of parameters in the formulation of the Eco-DRR Assessment Tool for Mangrove Ecosystem Services. After the selection of the parameters to be used both for Ecological and Social Assessment, these were grounded in the study site to test their reliability, compatibility, and accuracy before and after data collection. Moreover, the formulated assessment tool was reviewed by the experts working in mangrove ecosystem and related disciplines incorporated in the study. The process and data collection during the pre and post testing were analyzed and discussed to understand their significance in the creation of Eco-DRR assessment tool for the target ecosystem. Finally, the substantial parameters were selected to be included in the final draft of the Eco-DRR tool. The Eco-DRR tool showed promising results after testing it in the selected study site. Each parameter provided data that can reflect the significant role of the mangroves in terms of climate change mitigation, prevention of coastal erosion, tsunami or extreme tidal wave energy reduction, flood or storm surge barrier, and biodiversity protection. These interventions are connected to the different frameworks working in Ecosystem-based Solution similar to the Sendai Framework. The results and analyses of the parameters proved their relevance in managing the impact of natural disasters through their application and relationship to the Sendai Framework. Later in the analysis, the parameters used to evaluate the DRR capacities of mangroves are consolidated to comprise the “Ecosystem-based Disaster Risk Reduction (Eco-DRR) Assessment Tool for Mangrove Ecosystem Services” as fulfilment to the core objective of this study
