This study presents an exploratory, legitimate, and fiscal analysis of potential public financing pathways that can enable Local Government Units (LGUs) to pay premiums for parametric insurance schemes aimed at protecting and restoring mangrove and marine ecosystems. As climate threats intensify, the integration of risk financing instruments such as parametric insurance into local planning offers a proactive approach to ecosystem-based disaster risk reduction and climate adaptation. It assesses the legal permissibility, operational feasibility, and audit readiness of using various LGU-managed or nationally administered public funds to support insurance premiums.
