Risk Communication and Community Preparedness for Natual Disasters: Basis for Enhancing Local Disaster Risk Reduction and Management (LDRRM) Strategies

Abstract

Natural disasters continue to pose significant threats to communities worldwide, emphasizing the need for effective risk communication to strengthen disaster preparedness and resilience. This study examined risk communication and community preparedness for natural disasters as a basis for enhancing Local Disaster Risk Reduction and Management (LDRRM) strategies. Specifically, it sought to identify the risk communication strategies commonly employed by local governments during natural disasters, examine their effectiveness in improving community preparedness based on existing literature and policy documents, and synthesize evidence-based measures that can strengthen local risk communication and disaster preparedness initiatives. The study employed a descriptive narrative review using a quantitative approach, relying exclusively on secondary data obtained from peer-reviewed journal articles, government publications, policy documents, technical reports, and institutional publications published between 2021 and 2026. Relevant literature was systematically identified, screened, and organized using a structured literature review matrix, while thematic analysis was utilized to synthesize the extracted evidence according to the study objectives. The findings revealed that local governments employ diverse risk communication strategies, including multi-channel communication systems, early warning systems, digital technologies, social media platforms, community-based communication, public information campaigns, stakeholder collaboration, and participatory governance. The reviewed literature consistently demonstrated that these strategies are most effective when they provide timely, accurate, accessible, and credible information while promoting continuous community engagement, disaster education, institutional coordination, and public participation. Furthermore, the synthesis highlighted that effective risk communication contributes to increased disaster awareness, improved risk perception, enhanced public trust, stronger community participation, and greater preparedness capacities, ultimately strengthening community resilience. The review also identified evidence-based measures for improving local disaster risk communication, including the adoption of inclusive communication approaches, continuous disaster preparedness education, integration of local and indigenous knowledge, strengthened institutional collaboration, regular evaluation of communication strategies, and the strategic use of emerging communication technologies. Overall, the study concludes that effective and evidence-based risk communication is fundamental to strengthening Local Disaster Risk Reduction and Management (LDRRM) strategies and fostering resilient, adaptive, and disaster-ready communities.
