The increasing intensity and frequency of disasters in the Philippines continue to threaten the safety, stability, and resilience of local communities, particularly those in highly exposed and hazard-prone provinces like Pangasinan. Disasters—both natural and human-induced—continue to disrupt human security, economic stability, and community resilience across the Philippines. Given its location along the Pacific Ring of Fire and Typhoon Belt, the country faces recurrent hazards such as floods, typhoons, earthquakes, and landslides. This study assessed the disaster mitigation response of selected municipalities and a city in the 5th District of Pangasinan, with the aim of evaluating the level of preparedness and effectiveness of local disaster risk reduction and management (DRRM) systems, identifying significant differences among stakeholders, and developing a validated intervention program to strengthen community resilience. Using a mixed-methods research design, quantitative data were gathered through structured questionnaires administered to 239 respondents, composed of MDRRMO personnel, civic organization representatives, and community members, while qualitative data were collected through key informant interviews. The quantitative results, analyzed through weighted mean and Kruskal–Wallis tests, revealed that LGUs were highly prepared in terms of planning and training but only moderately prepared in resource allocation. The overall effectiveness of disaster mitigation response was rated effective, though funding and coordination gaps persisted. Qualitative findings supported these results, identifying challenges such as limited financial resources, inadequate equipment, weak inter-agency coordination, and inconsistent community participation. The study concluded that the 5th District of Pangasinan demonstrates commendable progress in DRRM implementation, yet disparities among LGUs highlight the need for equitable funding, stronger coordination mechanisms, and continuous capacity-building.
