Abstract

Coastal erosion poses a severe and growing threat to shoreline communities in Thailand, particularly in Samut Sakhon Province, where socioeconomic vulnerability and environmental degradation intersect. In this study we employ a mixed-methods approach to examine the mechanisms of community-based adaptation through the lens of the environmental education process (EEP). The approach integrates qualitative interviews (n = 85), quantitative surveys (n = 364), and spatial vulnerability mapping. The findings reveal significant economic insecurity, low levels of community participation in environmental organizations, and limited knowledge and preventive behavior regarding coastal erosion. Statistical analysis indicates a strong correlation between adaptive behavior and various factors, including knowledge, attitudes, community participation, access to information, and land use. Knowledge emerges as the strongest predictor of adaptive behavior (β = .389, p < .001). These insights form the basis of a participatory adaptation model that connects local knowledge systems with nature-based solutions and environmental learning frameworks. The study emphasizes the significance of integrating education, participatory governance, and ecosystem restoration to enhance coastal resilience. The proposed model serves as a scalable foundation for policy innovation and sustainable shoreline management in vulnerable coastal regions.
