Facilitators And Barriers

The understanding of factors that influence technology adoption in emergency planners is foundational for ensuring resilient communities to hazards in the future. We explore these factors through an interdisciplinary, social-ecological science lens. In this thesis, we use cultural evolutionary theory to understand the facilitators and barriers of Light Detection and Ranging (lidar) adoption in flood risk management, as a case study of technology adoption for long-term risk mitigation. We then disseminate our findings through three educational outlets: a webinar, a white paper (Appendix A), and a Story Map. This thesis contributes to our intellectual understanding of technology adoption, as well as provides information to minimize barriers to lidar uptake in Idaho. In the first chapter of the thesis, we used a mixed-methods empirical study to measure the facilitators of lidar adoption as a risk mitigation tactic in Idaho, Oregon, and Washington. Previous studies disproportionately focused on individual predictors of risk mitigation behavior such as risk perception, without identifying the contextual and collective drivers of risk mitigation behavior. We address this gap by examining both the individual (e.g., direct experience, risk-taking attitude, risk perception) and collective predictors (e.g., peer influence, network expertise) of lidar adoption regionally. We found that peer influence, or the proportion of lidar users in a respondent’s social network, network strength, network expertise, and risk perception significantly increase the likelihood of an individual to adopt lidar. The findings of this chapter contribute tounderstanding the role of collective predictors in long-term risk mitigation behavior and provide a foundational basis for future disaster research. In the second chapter of the thesis, we developed three educational outreach products with varying audience and intention in mind. These products addressed barriers identified in our semi-structured interviews and survey instrument from our mixed-methods empirical study discussed in Chapter One. The first product was a webinar that was attended by 65 flood risk managers and included a panel of cross-sector participants. The second product was a white paper, intended for the Idaho Geospatial Council-Executive Committee and Elevation Technical Working Group. With input from these groups, the product will eventually be used to ask for a lidar liaison position and lidar acquisition budget for Idaho. The Story Map accompanies the white paper and provides detailed account of various lidar applications throughout Idaho. The Story Map showcases content from 10 different lidar stakeholders. Both the white paper and Story Map exist in digital formats that are easily shareable and are considered living documents that can be updated as needed. The overarching goal of this thesis was to understand the facilitators and barriers of lidar adoption and increase uptake of lidar adoption in Idaho. Chapter One focuses on intellectual scholarship and is formatted as a manuscript for publication in the Climate Risk Management journal. Chapter Two focuses on applied scholarship with the greater lidar community. Appendix A is the white paper, Appendix B is a copy of the semi-structured interview instrument, and Appendix C is a copy of the survey instrument. Reference sections follow each chapter individually. This project was funded by the U.S. Department of Homeland Security Grant No. EMS-2019-CA-00030

Abstract. Public perception of flood risk and flood risk information is often overlooked when developing flood risk management plans. As scientists and the public at large perceive risk in very different ways, flood risk management strategies are known to have failed in the past due to this disconnect between authorities and the public. This paper uses a novel approach in exploring the role of public perception in developing flood risk communication strategies in Europe. Results are presented of extensive quantitative research of 1375 questionnaire responses from thirteen communities at risk across six European countries. The research forms part of two research projects funded under the 2nd ERA-Net CRUE Funding Initiative: URFlood and FREEMAN. Risk perception is conceptualised as a pillar of social resilience, representing an innovative approach to the issue. From this process recommendations are identified for improving flood risk management plans through public participation.

Flood Risk Management

Abstract. Sustainable flood risk management (SFRM) has become popular since the 1980s. Many governmental and non-governmental organisations have been keen on implementing the SFRM strategies by integrating social, ecological and economic themes into their flood risk management (FRM) practices. However, justifications for SFRM are still embryonic and it is not yet clear whether this concept is influencing the current policies in different countries. This paper reviews the past and present flood management approaches and experiences from flood defence to FRM in four developed countries with the aim of highlighting lessons for developing mega deltas. The paper explored recent strategies such as “Making Space for Water, PPS 25, and NPPF” in the UK; “Room for Rivers” in the Netherlands which was promoted to cope with flooding, integrate FRM with ideas on sustainability, and deliver good FRM practice for next generations. The United States has also established a sound National Flood Insurance Program (NFIP), and Japan has developed an advanced flood warning and evacuation contingency system to prepare for climatic extremes. These case studies showed some good lessons to achieve long term SFRM direction to deliver flood management practices with social-economic and environmental concerns. Most of developing coastal megacities especially in Asia are still heavily reliant on traditional hard-engineering approach, that may not be enough to mitigate substantial risks due to human (exist huge populations, rapid socio-economic growth, subsidence) and natural (climate change) factors. We understand different countries and cities have their own interpretation on SFRM, but recommend policy makers to adopt “mixed options” towards thinking about long term and sustainability that with social, economic and environmental considerations.

Flood Risk Perception

AbstractThe study of flood risk perception factors can be considered by using different paradigms. In an attempt to understand risk perception, two basic paradigms can be distinguished: rationalist and constructivist. The rationalist approach tends to focus on modeling, characterizing, and predicting behavioral results regarding various threats. According to the constructivist paradigm, threats are perceived as socially constructed. This review paper aims to assess the importance of the rationalist and constructivist approaches in research on flood risk perception and flood risk management more broadly by answering the questions: (1) Which paradigm dominates the research of flood risk perception?, (2) What is the relationship between rationalistic and constructivistic factors (e.g., stimulation, weakening, strengthening, etc.)?, (3) which factors are more effective in moderating attitudes toward flood risk? The paper concludes by pointing out the desired direction of research on flood risk perception from the perspective of improving flood risk management. In contemporary empirical works managing the perception of flood risk, a rationalistic approach that psychometrically searches for cognitive models dominates. Often, statistically obtained dependencies are mutually exclusive. Studies on perception that apply the constructivist approach are in an early stage of development, nevertheless providing consistent results. They indicate that the social, political, cultural, religious, and historical contexts shape the perception of flood risk. On the basis of the aforementioned information, research on flood risk in a constructivist approach should be expanded, as it provides a clear, often underappreciated catalog of contextual factors shaping risk perception and, importantly, simultaneously moderating the influence of rationalist factors on flood risk perception.

AbstractDespite an increasing number of people exposed to flood risks in Europe, flood risk perception remains low and effective flood risk management policies are rarely implemented. It becomes increasingly important to understand how local governments can design effective flood risk management policies to address flood risks. In this article, we study whether high flood exposure and flood risk perception correlate with the demand for a specific design of flood risk management policies. We take the ideal case of Switzerland and analyze flood risk management portfolios in 18 flood-prone municipalities along the Aare River. We introduce a novel combination of risk analysis and public policy data: we analyze correlations between recorded flood exposure data and survey data on flood risk perception and policy preferences for selected flood risk management measures. Our results indicate that local governments with high flood risk perception tend to prefer non-structural measures, such as spatial planning and ecological river restoration, to infrastructure measures. In contrast, flood exposure is neither linked to flood risk perception nor to policy preferences. We conclude that flood risk perception is key: it can decisively affect local governments’ preferences to implement specific diversified policy portfolios including more preventive or integrated flood risk management measures. These findings imply that local governments in flood-prone areas should invest in raising their population’s awareness capacity of flood risks and keep it high during periods without flooding.

Efficacy Factors

AbstractWhen attempting to communicate flood risk, trust in and perceptions toward risk information dissemination as well as individual efficacy factors can play a significant role in affecting risk-mitigation motivation and intention. This study seeks to examine how risk communication, risk perception, and efficacy factors affect evacuation motivation and behavioral intentions in response to a presumed flood risk, as based on a conceptual framework guided by protection motivation theory. An online survey was administered to college students (N = 239) from a region that is subject to sea level rise and storm surges. Path analysis results indicate that, while less information-source trust predicts greater risk perception, greater information-source trust predicts greater mitigation-information-seeking intention, lower self-efficacy, and stronger response efficacy. As lower mitigation-information-seeking intention similarly predicts greater risk perception, greater mitigation-information-seeking intention also predicts stronger response efficacy. Significant predictors of evacuation motivation include lower risk perception as well as greater information-source trust, severity perception, and response efficacy. Implications of these findings are discussed in terms of information dissemination channels, messaging strategies, and recent severe flooding events.
