Public perception and preferences for coastal risk management: Evidence from a convergent parallel mixed-methods study.

Coastal ecosystems are exposed to unprecedented levels of human pressure and to the cumulative effects of climate change. Altogether, these threats have been exposing coastal areas to augmented hazardous processes, leaving communities highly vulnerable to coastal risks and challenging the coastal management paradigm. Disregarding public perceptions of coastal risk management may be myopic and, thus, an obstacle to the success of the efforts towards coastal risks' mitigation and adaptation. Therefore, this study aims at comprehensively ascertain public perception and preferences for coastal risk management, through a mixed-methods approach. The quantitative study accounted for 3028 participants that enrolled in the population-based survey. The qualitative study accounted for 320 participants that responded to the e-interview. Data were analysed independently and triangulated for further interpretation. Evidence from this study suggests that citizens prioritize the intrinsic value of coastal systems, when favouring a risk adaptation strategy. Therefore, ecosystem-based adaptation measures were highlighted, in detriment of grey infrastructure. Additionally, and due to the reported high levels of public authorities' distrust, the public seems to urge for a transition from a technocratic to a participatory coastal management, in which public's preferences are legitimized. Consequently, and in order to decentralize coastal governance, citizens demonstrated a proactive disposition to actively engage in coastal management. Findings from this study were discussed in order to provide guidance to the development of tailored coastal management initiatives and policy tools, which are expected to be effective at enhancing coastal communities' resilience to hazardous processes and augmenting citizens' engagement in coastal management.
