Effective Messages to Motivate Mitigation Behavior: Experiments Testing Self-Efficacy, Social Norms, and Messages

JungKyu Rhys Lim, University of Maryland

Hurricanes and wildfires are the two most federally-declared disasters in the United States. Self-efficacy and social norms messages may help at-risk individuals adopt hurricane and wildfire mitigation behaviors. However, most studies have not yet developed and tested communication messages that can motivate the public’s mitigation behaviors using randomized experiments, yet took exploratory approaches based on surveys and correlations. This study simultaneously tests mitigation messages (self-efficacy, social norms) through 4 X 3 online between-subject experiments with U.S. adults in disaster-prone states (California, Florida, Texas). This study identifies what and how messages (self-efficacy, social norms) motivate at-risk individuals to take mitigation behaviors.

Behavior Analysis of Socially Vulnerable Households Responding to Planned Power Shutoffs

Youngjib Ham, Texas A&M University Seulbi Lee, Texas A&M University

How can we assess the impact of planned power shutoffs for preventing wildfires to community members, especially for socially vulnerable populations? This project will survey to empirically characterize what and how social factors would affect residents’ behavior responding to planned power shutoffs. Based on the survey results, we will develop the agent-based model to examine what factors make socially vulnerable populations more fragile to utility service disruptions. Analyzing the relationships between households' social vulnerability and their behavioral response to planned power shutoffs will inform policy decisions for both preventing wildfire risk and minimizing the adverse impact by utility service disruptions.

Assessing the Influence of Active Learning on Perceptions and Household Wildfire Mitigation Behavior

Brittany D Brand, Boise State University Carson MacPherson-Krutsky, Boise State University

Our study examines how knowledge, perceptions, and attitudes toward wildfire mitigation influence the mitigation behavior of residents of Boise’s Wildland Urban Interface (WUI). We further examine the effectiveness of active-learning-based outreach in shifting perceptions and attitudes, and positively influencing mitigation behavior. Methods include a questionnaire implemented before and after an education workshop designed to help participants better understand WUI hazards, personalize household risk, and develop positive attitudes toward taking mitigation and preparedness actions. Our research will demonstrate the efficacy of active-learning to engage homeowners in a way that helps them personalize risk and develop positive attitudes toward preparing.

Promoting Mitigation Through Post-Disaster Small Business Recovery Programs

Sua Kim, University of Utah Divya Chandrasekhar, University of Utah

Small businesses are critical stakeholders of community recovery, but they are often less attended to in the aftermath of disasters, which leaves them vulnerable to the next event. Policymakers could use this recovery moment to promote mitigation, but do they? This study uses a case study approach to examine whether and how small business recovery programs promoted mitigation planning after three recent disasters (2012 Hurricane Sandy, 2016 Hurricane Matthew, and 2017 Hurricane Harvey). The findings of this study will help assess whether post-disaster recovery programs are promoting mitigation planning among small businesses as well as identify areas of policy improvement.

The Intersection of Mitigation Measures on Household Adaptation to Climate Change

Brianna Castro, Harvard University

This study investigates micro-level climate change adaptation in two North Carolina communities. How do differentially vulnerable residents understand climate risks, consider government mitigation efforts, and adapt at the household-level? This question is addressed through ethnographic fieldwork, stakeholder interviews, and policy review. The site of study is Dare County, where the socioeconomically vulnerable Inner Banks contrast the affluent Outer Banks. North Carolina’s mitigation efforts are on the rise after Hurricane Florence, yet research is needed on how these efforts impact household-level climate response. Interactions between state and local policies and household-level adaptations are crucial to understanding how communities navigate climate risk.

How Climate-Induced Coral Bleaching Impacts Community Wellbeing and Hazard Vulnerability

Kelly Dunning, Auburn University

Coral reefs are experiencing global decline from climate stress (bleaching). This research asks whether multi-scaled investments in long-term coral reef conservation planning in the case of South Florida reefs have 1) mitigated vulnerability to climate stress and 2) enhanced community well-being? We will use interviews, policy documents, and a case study in South Florida due to its high levels of poverty and income inequality. This research will link conservation governance, outcomes, and well-being using highly cited frameworks (i.e. IUCN). It can serve as a learning tool for other places managing coral reefs in the face of climate change hazards.

Examining Digital Vulnerability to Flooding Among Subsidized Housing Residents in Florida

Yan Wang, University of Florida Seungbeom Kang, University of Florida

Despite the increasing role of Information and Communication Technologies (ICTs) in disaster mitigation work, little is known about the influence of the digital divide (DD) on disaster risk reduction. Focusing on the flood-prone neighborhoods in Florida, this project intends to quantify DD considering its different levels and to disentangle the relationship between DD and flood vulnerability among subsidized housing residents by using multiple quantitative methods. The research will be among the first to examine the digital inequality in the flood-prone neighborhoods and will add another critical layer to their vulnerability: “digital” vulnerability.

The Traditional Ecological Knowledge and Mitigation Nexus: The Pamunkey Indian Reservation

Nicole Hutton, Old Dominion University Thomas Allen, Old Dominion University

Land use change since colonial times, recent sprawl, and sea level rise (SLR) have caused extensive changes in the Chesapeake Bay’s tributary streams, such as the Pamunkey River, on which the Pamunkey Indian Reservation is located. This pilot study assesses the human-water relationship of the Pamunkey Indian Tribe using Geographic Information Systems (GIS) in a participatory research process to prioritize SLR mitigation and adaptation strategies for the reservation. Results will provide a historical, spatial record of the Pamunkey Indian Tribe’s human-water relationship, identify traditional ecological knowledge (TEK) based mitigation and adaptation options and advance TEK integration in resilience planning.

Understanding the Impacts of Managed Retreat and Resettlement on Informal Communities

Monique A. Lorenzo Pérez, Ohio State University Santina Contreras, Ohio State University

Planned retreat and relocation are frequently discussed in hazard mitigation planning as approaches useful for improving the livelihoods of communities living in hazardous environments. However, in environments with highly vulnerable areas, such as informal communities, the relocation process may inadvertently uncover new risks, such as exposure to new types of hazards and disruption of community networks. This research explores these issues through a case study analysis of the resettlement of an informal community in Puerto Rico. By assessing the process of managed retreat and resettlement, this project aims to contribute to the implementation of hazard mitigation efforts in vulnerable communities.

Reducing Health Disparities of Natural Disasters: Evidence from Building Codes

Ausmita Ghosh, East Carolina University Jamie Kruse, East Carolina University

The objective of this research is to improve understanding of the health benefits of community-level built environment resilience in the face of hurricanes. Our quasi-empirical empirical strategy will exploit spatial and temporal variation in implementation of hazard mitigation legislation to estimate their impact on health. While a growing literature has sought to quantify property losses averted by stricter building codes, an assessment of health impacts will shed light on the broader benefits of such mitigation programs which is critical to formulating an effective policy response.

The following forthcoming Mitigation Matters Research projects were accepted as part of the October 2019 call for mitigation-related research. Final reports will be published online when research is completed.

Reducing Disparity in Disaster Recovery by Modeling Social Vulnerabilities

Maura Allaire, University of California, Irvine
Romeo Ignacio, University of California, Irvine
Aishwarya Borate, University of California, Irvine

Flood losses continue to rise dramatically and can deepen wealth inequality caused by the uneven distribution of impacts and recovery aid. Crucial adaptation decisions must often be made without adequate understanding of social vulnerability. While a variety of vulnerability indices have been created, they are rarely validated. This study will develop validated metrics for social vulnerability using high-resolution datasets. By assessing temporal and spatial variation in these metrics, we can determine why some communities are more vulnerable than others. This can enable integrated risk analysis nationwide, reduce inequities in disaster recovery, and improve public investment decisions for adaptation to evolving hazards.

The Role of Insurance in a Tornado-Impacted Community

Ji Yun Lee, Washington State University
Guirong Yan, Missouri University of Science and Technology

The objectives of this research are to determine if sufficiently insured houses positively impact community resilience and to quantify the impact of insurance on tornado-impacted community resilience. An online survey containing in-depth, semi-structured interviews will be conducted with residents in Jefferson City, Missouri, which was struck by an EF-3 tornado in May 2019. The survey will investigate the explicit relationship between insurance policy and house recovery. The results will provide guidance on how insurance can be used broadly in resilience planning to achieve both short- and long-term community resilience goals.

Pre-Planning for Post-Disaster Rehousing of Public Housing Residents: A Case Study of Salt Lake County

Sayma Khajehei, University of Utah
Divya Chandrasekhar, University of Utah

Public housing residents and subsidized housing renters face serious challenges in terms of housing in the aftermath of disasters, but cities with little experience of major disasters may have limited plans for how to house these socially vulnerable residents. Using Salt Lake County UT as a case study, this research will look for pre-disaster policies to provide post-disaster housing to public housing residents. Findings will improve our understanding of whether cities are prepared to provide housing to public housing residents after disasters and how to help these socially vulnerable populations to recover in the long run.

From the Ashes: Mitigation Policy after Wildfire in California

Ronald Schumann, University of North Texas
Miranda Mockrin, U.S. Forest Service
Sherri Brokopp Binder, BrokoppBinder Research & Consulting
Alex Greer, State University of New York at Albany

This study investigates policy and practice barriers to wildfire mitigation in three California communities. How does recent wildfire experience affect housing recovery programming, land use planning, and requirements for household-level mitigation? We will address this question via stakeholder interviews, neighborhood tours, and policy document review. Wildfires that destroy whole communities are increasingly prevalent, yet there is need for more wildfire-centric research. California communities are struggling to facilitate an expeditious recovery that reduces future wildfire vulnerability. Absent federal wildfire risk governance standards, interactions between state and local policies become crucial to understanding how communities navigate this challenge.

Determinants of Hospital Disaster Mitigation Practice Implementation in the Dominican Republic

Nicole Errett, University of Washington
Ashley Morales-Cartagena, Pontificia Universidad Católica Madre y Maestra

Mitigation practices can minimize hospital service disruption in the event of a disaster. Yet, absent formal requirements, it remains unknown how or why mitigation practices are implemented in hospitals worldwide. We will use the Dominican Republic—a disaster hot spot—as a case study to understand the factors associated with hospital implementation of mitigation practices, as outlined in the World Health Organization Safe Hospital Framework. Guided by the Consolidated Framework for Implementation Research, we will conduct semi-structured interviews with hospital administrators in Santo Domingo and Punta Cana-Bavaro. Findings can guide policy development to facilitate hospital disaster mitigation practice implementation.

The Effect of Federal Recovery Funds on Mitigation Behavior

Maria Watson, Texas A&M University
Siyu Yu, Texas A&M University

Research and practice have increasingly acknowledged the importance of moving development out of hazardous areas. This research examines whether disaster recovery loans encourage or discourage residential or business mobility. We will employ a mixed-methods research design using quantitative data from local and federal agencies, as well as semi-structured interviews. Deeper knowledge on how recovery funding influences adaptive behavior can inform more effective approaches as practitioners reevaluate how federal assistance can conflict with local initiatives. This work can foster a more coordinated strategy between federal agencies and local communities.

What Drives Hazard Mitigation Policy Adoption? FEMA’s Property Buyout Program in Virginia

Qiong Wang, Virginia Tech
Yang Zhang, Virginia Tech
Kristin Owen, Virginia Department of Conservation and Recreation

What are the drivers and barriers to adopting the Federal Emergency Management Agency’s property buyout program in flood-prone communities in Virginia? Available data includes an online survey of approximately 296 local floodplain managers in Virginia, American Community Survey census data, and FEMA’s buyout database. Qualitative and quantitative methods will be applied to identify four categories of factors. Most hazard mitigation actions are subnational, therefore, understanding factors of hazard mitigation policy adoption at the local level will advance local policy innovation within a federally defined framework. This knowledge will help maximize opportunities for hazard mitigation and offer insights for federal program improvement.

Playing Strategically or Following Suit? Interdependence and Social Norms in Wildfire Mitigation

Hilary Byerly, University of Colorado Boulder
Hannah Brenkert-Smith, University of Colorado Boulder

James Meldrum, U.S. Geological Survey

In the wildland-urban interface, wildfire risk is interdependent—determined by both a household’s mitigation and that of neighboring properties. Risk mitigation may also be influenced by neighbors through social norms or reciprocity. Yet, how households consider neighboring parcels in their perceptions and mitigation behavior is unclear. Through semi-structured interviews with homeowners, we explore perceptions of their parcel’s surrounding landscape—both biophysical and social—and its effect wildfire risk. We identify which neighbors’ behaviors and expectations are salient and their association with mitigation actions. Results will inform the design of a large-scale field experiment with a local practitioner to increase engagement in wildfire mitigation.

Safhaus: Affordable, Disaster-Resistant Housing

George Elvin, North Carolina State University
Reide Corbett, Coastal Studies Institute
Robert McClendon, Coastal Studies Institute
David Hill, North Carolina State University

Socially vulnerable households often live in low-quality, light-weight wood frame housing that is easily damaged during disasters. The Safhaus re-envisions light-weight wood framing in a way that maintains the benefits of affordability, sustainability, and familiarity, while significantly increasing its resilience in disaster. It offers protection from hurricane- and tornado-force winds, elevation levels that avoid flooding, and an enclosure system that reduces damage from wind and wildfire. This research will deploy and monitor a sensor network in prototype construction to determine if the Safhaus can provide enhanced hazard mitigation without increasing construction costs.
