DETERMINING TSUNAMI DISASTER MITIGATION AREAS BASED ON THE PRESENCE OF MANGROVE ECOSYSTEMS

Abstract

The mangrove ecosystem plays a crucial role in tsunami disaster risk mitigation due to its capacity to attenuate wave energy and protect coastal areas. This study aims to develop a tsunami disaster mitigation concept based on mangrove ecosystem data by utilizing spatial analysis through Geographic Information Systems (GIS). The method employed is a quantitative descriptive approach, involving an overlay analysis between tsunami hazard data layers and mangrove distribution in Indonesia. This integration is expected to serve as a foundation for formulating effective and innovative mitigation action plans, emphasizing the strategic use of spatial data to support evidence-based planning. The evidence-based approach in this study provides a solid scientific foundation for policymaking in tsunami disaster mitigation, focusing on mangrove ecosystem recovery. Furthermore, the use of spatial data enables more accurate identification of priority areas, making the resulting policies more relevant to actual field conditions. The analysis indicates that integrating spatial data with empirical evidence is the key to producing more targeted, transparent, and accountable policies. This approach not only reduces reliance on assumptions but also enhances efficiency, equity, and sustainability in decision-making processes. With proper implementation, this model has the potential to generate more responsive, equitable, and effective tsunami disaster mitigation policies while supporting the long-term conservation of coastal environments.
