A growing focus is being placed on both indi-viduals and communities to adapt to flooding as part of the Sendai Framework for Disaster Risk Reduction 2015-2030.Adaptation to flooding requires sufficient social capital (linkages between members of society),risk perceptions (understanding of risk),and self-efficacy (self-perceived ability to limit disaster impacts) to be effective.However,there is limited understanding of how social capital,risk perceptions,and self-efficacy interact.We seek to explore how social capital interacts with variables known to increase the likelihood of successful adaptation.To study these linkages we analyze survey data of 1010 respondents across two communities in Thua Tien-Hue Province in central Vietnam,using ordered probit models.We find positive correlations between social capital,risk perceptions,and self-efficacy overall.This is a partly contrary finding to what was found in previous studies linking these concepts in Europe,which may be a result from the difference in risk context.The absence of an overall negative exchange between these factors has posi-tive implications for proactive flood risk adaptation.
