Impacts of hazard maps on individual reaction? Results from a case study in South Tyrol, Italy

This study investigates the impact of hazard maps on people’s risk awareness, risk perception and willingness to engage in risk management activities in South Tyrol, Italy. By comparing empirical survey data from municipalities with and without approved hazard maps, the research aims to understand how these maps influence people’s awareness and attitudes towards natural hazards. The results show that while hazard maps significantly improve risk perception and encourage proactive behaviour, their effect on knowledge about risk relevant tools and measures remains limited. There is a high level of uncertainty and misinformation regarding existing risk mitigation measures, particularly in communities without approved hazard maps. The results show that hazard maps have a significant impact on public risk perception. In communities with approved hazard maps, people perceive a greater need for additional protective measures and have a lower sense of security in case of a natural hazard event. The study also shows that hazard maps increase people’s willingness to become more involved in risk management activities. The study emphasizes the importance of targeted risk communication strategies and suggests that hazard maps should be complemented by ongoing risk communication initiatives and participatory formats to achieve sustainable engagement and increase people’s preparedness. Additionally, the research highlights the potential of hazard maps to raise awareness and encourage active participation but also identifies challenges and the need for comprehensive follow-up activities to ensure long-term impact.
