Hazard of Interest: Climate Change
Methods: Quantitative (surveys) and Qualitative (interviews and focus groups)
Key Research Issues: Improving our understanding about the context of decision processes about how to manage fresh water resources on Pacific Islands under the changing climate.
Key Research Findings: People managing freshwater resources in Hawaii are highly educated and experienced in diverse professions, they perceive climate change as posing a worrisome risk, and they would like to be better informed about how to adapt to climate change. decisions can be characterized on several key dimensions including purpose (optimization and evaluation), time horizon (short term and long term), level of information uncertainty (known, uncertain, deeply uncertain, and completely unknown), and information type (quantitative and qualitative). The climate information most relevant to decision makers includes vulnerability assessments incorporating long-term projections about temperature, rainfall distribution, storms, sea level rise, and streamflow changes at an island or statewide scale. The main barriers to using available climate information include insufficient staff time to locate the information and the lack of a clear legal mandate to use the information.

Hazard of Interest: Tornado
Methods: Semi-structured interviews and close-ended questionnaires
Key Research Issues:
• This research examines two successive, potentially tornadic events that occurred in Goderich, Ontario, Canada on 21 August 2011 and 24 August 2011.
• The purpose of this socio-behavioral study was to investigate the influence of previous disaster experience on risk perception and response to a low-probability, high-impact disaster.
Key Research Findings:
• Physical cues were the primary motivators of protective action on 21 August 2011, while the Environment Canada tornado warning was the primary motivator on 24 August 2011.
• Respondents were more likely to take protective action during the subsequent storm on 24 August 2011, regardless of whether they were physically present for the tornado on 21 August 2011. This highlights the important influence of indirect disaster experience on hazard perception and response.
• Socio-demographics were not found to influence protective decisions made on 21 August 2011, while gender (female) was related to decision-making on 24 August 2011.
• The intense media coverage of the impacts of the 21 August 2011 tornado may have contributed to a social amplification of risk on 24 August 2011.
