Ecosystem based adaptation for coastal resilience: Lessons from managing Tidal flooding in North Java
Keywords:

Tidal flooding exacerbated by land subsidence presents a critical, persistent hazard along the North Java Coast, necessitating the adoption of sustainable, ecosystem-based solutions. This study employs a comprehensive review of existing literature and implementation reports to assess the efficacy of mangrove Ecosystem-based Adaptation (EbA) initiatives in enhancing coastal resilience. The research synthesizes findings across four core themes: physical effectiveness, socio-economic co-benefits, the role of community participation, and institutional challenges. Findings confirm that established mangrove green belts are highly effective, delivering significant wave energy reduction (60–85%) and generating crucial socio-economic co-benefits, including revitalized fisheries and nascent ecotourism. Critically, however, the persistence and scalability of these successes are fundamentally challenged by non- ecological systemic barriers, primarily pervasive land tenure insecurity and fragmented inter-agency policy coordination. This study contributes by emphasizing that successful EbA implementation in dynamic coastal environments hinges upon robust adaptive governance that bridges local stewardship with coherent, long-term policy integration. The compelling, hard-won lessons from North Java provide a powerful global mandate: achieving sustainable coastal resilience demands the permanent prioritization of natural infrastructure through comprehensive institutional reform.
