Long-Term Perspectives on Climate Hazard Resilience in Southeast Asia: Communities, Institutions, and Knowledge Systems

Southeast Asia (SEA) is one of the world’s most climate vulnerable regions, where rising temperatures, sea-level rise, and erratic rainfall patterns are intensifying climate-induced extreme events such as floods, tropical cyclones, heatwaves, droughts, and landslides. Rapid urbanization, high population density in coastal and river-delta areas, and strong reliance on climate-sensitive livelihoods (especially agriculture and aquaculture) amplify vulnerability and create cascading risks across food systems, health, infrastructure, and livelihoods. At the same time, SEA’s diverse geographies and governance structures mean that climate resilience is uneven across region not only by physical exposure, but also by inequality, access to services, social protection, and institutional capacity. This research focuses on historical studies of resilience to climate hazards in Southeast Asia to address gaps in understanding long-term socio-ecological adaptation and knowledge integration. This study aimed to evaluate historical resilience strategies, benchmark traditional ecological knowledge integration, identify community-based adaptive practices, analyze socio-political influences, and compare methodological approaches. A systematic analysis of interdisciplinary literature spanning in the last two decades across Southeast Asia was conducted, incorporating qualitative ethnography, archival research, paleoenvironmental proxies, and quantitative modeling. Findings reveal robust integration of indigenous knowledge with scientific data enhancing adaptive capacity, though knowledge erosion and policy marginalization persist. Socio-cultural and political contexts  of SEA critically shape climate resilience, yet detailed institutional analyses remain limited. Methodological diversity enriches insights but faces challenges in data validation and standardization. On the other hand, community-based and locally-led adaptive practices demonstrate both incremental and transformative resilience. However, scalability and intergenerational transmission are threatened by socio-economic dynamics. This synthesis underscores the value of long-term, multi-method perspectives in capturing resilience dynamics while highlighting the need for deeper institutional engagement and improved knowledge co-production frameworks. These findings inform culturally grounded, historically informed climate resilience policies that recognize complex socio-ecological interactions and support sustainable adaptation across temporal and spatial scales in SEA and beyond.
