The role of social networks in relocation induced by climate-related hazards: an empirical investigation in China

Abstract

ABSTRACT Relocation is an adaptive strategy applied to prevent the threats of climate-related hazards. Thus, understanding the determinants of rural households’ adaptation decisions is crucial when informing policy interventions. This study explores the role of social networks (or peer groups) in geohazard-induced relocation using survey data (N = 516) from Chongqing, China. This study applies an instrument variable (IV) method and a series of robustness checks to confirm the findings. The results indicate that (1) social networks’ willingness to relocate (WTR) increases one’s relocation intention; and (2) people imitate their peers’ mobility choices by consciously observing and learning when facing uncertain climate-related hazard risks. Our findings contribute to comprehending whether and why social networks prompt population relocation decisions and help policymakers exploit the role of peer groups when implementing relocation-related policies in geohazard-prone regions.
