Public intention to participate in sustainable geohazard mitigation: an empirical study based on an extended theory of planned behavior

Giving full play to the public's initiative for geohazard reduction is critical for sustainable disaster reduction under a government-led top-down disaster governance approach. According to the public's intention to participate in geohazard mitigation activities, this study introduces the analytical framework of the theory of planned behavior (TPB), with attitudes, subjective norms, and perceived behavioral control as the primary explanatory variables, with three added explanatory variables: risk perception, disaster experience, and participation perception.Survey data obtained from 260 respondents in Jinchuan County, Sichuan Province, China, are analyzed using structural equation modeling and combined with multivariate hierarchical regression to test the explanatory power of the model. The results indicate that attitude, subjective normative, perceived behavioral control, and participatory cognition are significant predictors of public intention to participate. Disaster experience is negatively associated with public intention to participate. In addition, the extended TPB model contributes 50.7 % to the explanation of the behavioral intention of public participation.Practical suggestions and theoretical guidance are provided for strengthening geohazard risk management and achieving sustainable disaster reduction. In particular, it is concluded that, while correctly guiding public awareness of disaster reduction activities, policymakers should continue developing participatory mechanisms, paying attention to two-way communication bridges between the public and the government, uniting social forces, and optimizing access to resources.
