Addressing Challenges to Building Resilience Through Interdisciplinary Research and Engagement.

Resilient communities are less affected by, and recover faster from, natural disasters. To be resilient in rapidly changing contemporary environments subject to the effects of complex factors such as climate change and urbanization, communities must effectively and efficiently adapt to new conditions to minimize future risks. To develop resilience, the hazards to which the community is exposed and vulnerable (i.e., future hurricanes, subsidence, salt water intrusion) must be accurately assessed, the systems (i.e., natural, built, and social) must be well understood, and the community must be engaged in the proactive planning and priority setting process. An approach to building resilience that utilizes the adaptive capacity of planning highlights opportunities to work collaboratively across disciplines to incorporate models and data from different disciplines to reduce uncertainty. We present one interdisciplinary group's approach to addressing challenges to building resilience through proactive planning, including: (1) characterizing hazards more accurately; (2) improving understanding of the vulnerability of natural (e.g., climate and infrastructure) systems subject to hazards; and (3) capturing potential synergies from interactions between planning and policies that govern decisions about the design of human settlements in hazardous areas.

Integrating a Resilience Scorecard and Landscape Performance into a Geodesign Process.

Uncertainty about the impacts of sea level rise make the ability to forecast future spatial conditions a necessary planning/design tool. Geodesign integrates multiple fields of science with change/impact models and planning/design strategies. Proactive planning analyses such as newly developed scorecards allow for plan evaluation; design strategies can now be quantitatively assessed using landscape performance calculators. Neither have been explored as Geodesign tools. A Geodesign process was developed using the resilience scorecard to assess flood vulnerability using projections for the 100 year floodplain with sea level rise by 2100. Projections were used as a guide to develop a resilient master plan for League City, TX, USA. Future impacts of the plan are projected using landscape performance measures.

Evaluating the Impact of Race and Gender on Environmental Risk Perceptions in the Houston Neighborhood of Manchester.

Previous research has shown that white males tend to perceive risks from environmental exposures as lower than women and members of minority populations, often referred to as the white male effect. However, this effect was mostly demonstrated without regard to the actual lived environment experienced by the study participants. There is growing evidence that differences in risk perceptions cannot be adequately explained through race or gender. This cross-sectional study collected survey data from residents of Manchester, a small neighborhood in Houston, Texas, characterized by industrial sites, unimproved infrastructure, nuisance flooding, and poor air quality. Trained community members attempted a complete census within the geographically compact neighborhood. Logistic regression was used to estimate the relative effect of race on environmental health perceptions adjusted for generational age. In contrast to previous research, our study (N = 109) showed that nonwhite individuals perceived a lower environmental health risk compared with their white counterparts. Comparing female and minority racial groups with white males showed that on most issues, white males had the highest perception of risk. For example, adjusted for age, nonwhite respondents perceived the risk of contact with standing water as significantly lower than white respondents (odds ratio = 0.34; 95% confidence interval = 0.12-0.93). This study supports the hypothesis that when environmental conditions experienced by individuals are the same, minority groups tend to underestimate their risk compared with white males. One possible explanation put forth is that communal norms are created within minority populations through generations of exposure to negative environmental conditions compared with white populations.

Participatory Action Research: Tools for Disaster Resilience Education.

PURPOSE: Participatory action research can improve scientific knowledge and community capacity to address disaster resilience and environmental justice. Evidence from the literature suggests that resident participation enhances assessment of environmental risks, raises awareness, and empowers residents to fight for equitable distribution of hazard and climate risk adaptations. Yet, risk assessment and urban planning processes still frequently operate within expertise-driven groups without significant community engagement. Such fragmentation results in part from a lack of appreciation for community expertise in built environment adaptations and educational tools to support resident involvement in the often technical built environment planning processes. APPROACH: A participatory research and place-based education project was developed that enhanced co-learning between residents and researchers while collecting and analyzing local data on flood resilience in the built environment. Five research activities constitute the curriculum of resilience education on stormwater infrastructure: 1) establishment of partnership agreement/MOU, 2) participatory GIS to identify flooding issues, 3) water quality testing and health survey, 4) stormwater infrastructure assessment, and 5) urban/landscape design. Partners included high school and college students, residents, and environmental justice organizations. FINDINGS: Outcomes include a stakeholder approved infrastructure assessment smartphone application, neighborhood maps of drainage issues, a report of water containments, and neighborhood-scaled green infrastructure provisions and growth plans. Findings indicate that participatory research positively contributed to resilience knowledge of participants. VALUE: This paper outlines an interdisciplinary pedagogical strategy for resilience planning that engages residents to assess and monitor the performance of stormwater infrastructure and create resilience plans. The paper also discusses challenges and opportunities for similar participatory projects.

The development of a participatory assessment technique for infrastructure: Neighborhood-level monitoring towards sustainable infrastructure systems.

Climate change and increasing natural disasters coupled with years of deferred maintenance have added pressure to infrastructure in urban areas. Thus, monitoring for failure of these systems is crucial to prevent future impacts to life and property. Participatory assessment technique for infrastructure provides a community-based approach to assess the capacity and physical condition of infrastructure. Furthermore, a participatory assessment technique for infrastructure can encourage grassroots activism that engages residents, researchers, and planners in the identification of sustainable development concerns and solutions. As climate change impacts disproportionately affect historically disenfranchised communities, assessment data can further inform planning, aiming to balance the distribution of public resources towards sustainability and justice. This paper explains the development of the participatory assessment technique for infrastructure that can provide empirical data about the condition of infrastructure at the neighborhood-level, using stormwater systems in a vulnerable neighborhood in Houston, Texas as a case study. This paper argues for the opportunity of participatory methods to address needs in infrastructure assessment and describes the ongoing project testing the best use of these methods.

The Impacts of Exposure to Environmental Risk on Physical and Mental Health in a Small Geographic Community in Houston, TX.

Previous research has shown that communities with low average socioeconomic status (SES) and majority minority populations are more likely to be exposed to industrial buildings, waste facilities, and poor infrastructure compared to white communities with higher average SES. While some studies have demonstrated linkages between exposures to specific environmental contaminates within these communities and negative health outcomes, little research has analyzed the effects of environmental contaminants on the mental and physical health of these populations. A cross-sectional survey collected data from residents of Manchester, a small neighborhood in Houston, TX, that is characterized by industrial sites, unimproved infrastructure, nuisance flooding, and poor air quality. Our study (N = 109) utilized the 12 item Short Form Health Survey version 2 (SF12v2) to assess the general mental and physical health of the community. The community as a whole had reduced physical health scores compared to U.S. national averages. The time residents had lived in the neighborhood was also correlated with a reported reduction in physical health scores (r2 = 0.136; p-value <0.001). The association between time lived in the neighborhood and poorer health scores remained after adjusting for age, race, and gender (coef = -0.27, p-value <0.001). Mental health scores were within national averages and time spent living in the neighborhood did not appear to negatively impact respondent's mental health scores. These findings point to the need for more research to determine the potential for additive physical and mental health impacts in long-term residents in neighborhoods characterized by environmental justice issues.

Developing indicators to measure post-disaster community recovery in the United States.

Disaster recovery is a key capability of federal, state, and local government. To support this capability effectively practitioners need useful and validated metrics to document how well a community is recovering from a particular disaster. This study developed and categorised recovery indicators according to the Federal Emergency Management Agency (FEMA)'s Recovery Support Functions and Recovery Mission Area Core Capabilities through a literature review, an evaluation of the pre-disaster recovery plans for 87 coastal jurisdictions, and a case study of two communities (New Hanover County, North Carolina, and the City of Hoboken, New Jersey). Metrics identified in the literature were validated through the recovery plan review and the case study. The research team also identified sources for both baseline and current status data. Based on these findings, a user-friendly checklist for practitioners was established, which will be piloted with practice partners during a future disaster recovery initiative.

Confirming the Environmental Concerns of Community Members Utilizing Participatory-Based Research in the Houston Neighborhood of Manchester.

In the last few decades, there has been an increase in community-based participatory research being conducted within the United States. Recent research has demonstrated that working with local community organizations, interest groups, and individuals can assist in the creation of, and sustainability in, health initiatives, adoption of emergency protocols, and potentially improve health outcomes for at-risk populations. However little research has assessed if communal concerns over environmental contaminants would be confirmed through environmental research. This cross-sectional study collected survey data and performed surface water analysis for heavy metals in a small neighborhood in Houston, TX, which is characterized by industrial sites, unimproved infrastructure, nuisance flooding, and poor air quality. Surveys were completed with 109 residents of the Manchester neighborhood. Water samples were taken from thirty zones within the neighborhood and assessed for arsenic (As), barium (Ba), cadmium (Cd), chromium (Cr), lead (Pb), selenium (Se), silver (Ag), and mercury (Hg). Survey results showed that the vast majority of all respondents were concerned over proximity to industry and waste facilities, as well as exposure to standing surface water. Barium was discovered in every sample and many of the zones showed alarming levels of certain metals. For example, one zone, two blocks from a public park, showed levels of arsenic at 180 (µg/L), barium at 3296 (µg/L), chromium at 363 (µg/L), lead at 1448 (µg/L), and mercury at 10 (µg/L). These findings support the hypothesis that neighborhood members are aware of the issues affecting their community and can offer researchers valuable assistance in every stage of study design and execution.

Accounting for vulnerable populations in rural hazard mitigation plans: results of a survey of emergency managers.

Rural areas of the United States are uniquely vulnerable to the impacts of natural disasters. One possible way to mitigate vulnerability to disasters in rural communities is to have a high-quality hazard mitigation plan in place. To understand the resources available for hazard mitigation planning and determine how well hazard mitigation plans in rural counties meet the needs of vulnerable populations, we surveyed the lead planning or emergency management official responsible for hazard mitigation plans in 96 rural counties in eight states in the Southeastern United States. In most counties, emergency management was responsible for implementing the county's hazard mitigation plan and the majority of counties had experienced a presidentially declared disaster in the last 5 years. Our research findings demonstrated that there were differences in subjective measures of vulnerability (as reported by survey respondents) and objective measures of vulnerability (as determined by US Census data). In addition, although few counties surveyed included outreach to vulnerable groups as a part of their hazard mitigation planning process, a majority felt that their hazard mitigation plan addressed the needs of vulnerable populations "well" or "very well." These differences could result in increased vulnerabilities in rural areas, particularly for certain vulnerable groups.

Individual actual or perceived property flood risk: did it predict evacuation from Hurricane Isabel in North Carolina, 2003?

Individual perception of risk has consistently been considered an important determinant of hurricane evacuation in published studies and reviews. Adequate risk assessment is informed by environmental and social cues, as well as evacuation intentions and past disaster experience. This cross-sectional study measured perceived flood risk of 570 residents of three coastal North Carolina counties, compared their perception with actual risk determined by updated flood plain maps, and determined if either was associated with evacuation from Hurricane Isabel in 2003. Census blocks were stratified by flood zone and 30 census blocks were randomly selected from each flood zone. Seven interviews were conducted at random locations within selected blocks. Bivariate and multivariable analyses were conducted to produce crude and adjusted risk differences. Neither the designated flood zone of the parcel where the home was located nor the residents' perceived flood risk was associated with evacuation from Hurricane Isabel in the bivariate analysis. In the multivariable analysis, intention to evacuate and home type were important confounders of the association between actual risk and evacuation. The belief that one is at high risk of property damage or injury is important in evacuation decision making. However, in this study, while coastal residents' perceived risk of flooding was correlated with their actual flood risk, neither was associated with evacuation. These findings provide important opportunities for education and intervention by policymakers and authorities to improve hurricane evacuation rates and raise flood risk awareness.

Public participation in local government review of development proposals in hazardous locations: does it matter, and what do local government planners have to do with it?

Natural hazard investigators recommend that local governments adopt mitigation plans to help reduce hazard losses. However, such plans are unlikely to be effective unless a wide range of public stakeholders is involved in their creation. Previous research shows that stakeholder participation levels in hazard mitigation planning tend to be low, though there may be particular choices that local government planners can make to foster participation. We examine the importance of planners' choices and role orientations (i.e., beliefs regarding appropriate behavior in the workplace) for participation levels in site plan review, wherein local governments review site plans for proposed development projects to ensure compliance between project design and applicable plans and policies. Using a national sample of 65 development projects located in areas subject to natural hazards, and bivariate and multivariate analyses, we examine whether participation levels during site plan review depend upon planners' choices and role orientations, and whether participation levels are correlated with the incorporation of hazard mitigation techniques into development projects. We find significant correlations between participation levels and planners' choices, between participation levels and planner's role orientations, and between participation levels and the incorporation of hazard-mitigation techniques. We encourage local government planners to revisit their beliefs, choices, and behaviors regarding public participation in site plan review.

Understanding, managing, and minimizing urban impacts on surface water nitrogen loading.

The concentration of materials and energy within cities is an inevitable consequence of dense populations and their per capita requirements for food, fiber, and fuel. As the world population becomes increasingly urban over the coming decades, urban areas will dramatically affect the distribution of nutrients across the face of the planet. In many cities, technological developments and urban planning have been effective at reducing the amount of waste nitrogen that is ultimately exported to downstream surface waters, largely through investments in sanitary sewer infrastructure and wastewater treatment. There are, however, still large cities throughout the developed world that have failed to take advantage of these obvious innovations to reduce their impact on downstream ecosystems. In addition, very few cities have adequately addressed the problems of diffuse nitrogen pollution, instead city infrastructure is often designed to route this N directly into downstream ecosystems. In the developing world, many of these problems are more acute, as rapidly growing urban populations exceed the capacity of limited municipal infrastructure. Reducing urban N pollution of groundwaters and surface waters both locally and globally can only be achieved through cultural and political adaptation in addition to technological innovations. In this review, we will focus on the implications of an increasingly urban world population on local, regional, and global nitrogen cycles and propose a variety of approaches for minimizing and mitigating the impacts of urban N concentration.

Chapter 8 : Recovery after disasters : Achieving sustainable development, mitigation, and equity

Key considerations and critical issues that are not fully addressesd by the current disaster recovery literature are reviewed in this chapter. The focus is on achievement of equity, mitigation, and sustainable development, particularly through local participation in redevelopment planning and institutional cooperation. The process by which communities rebuild after a natural disaster are reviewed to provide a framework for a conceptual model for understanding local disaster recovery efforts. The conceptual and practical significance of this model are demonstrated by case studies. Conclusions are offered to advance current understanding as well as to define the implications for public policy in the Central United States.(AU)

Recovery after disaster : Achieving sustainable development, mitigation and equity

This papaer reviews key findings and raises issues that are not fully addressed by the predominant disaster recovery literature. Achievement of equity, mitigation and sustainable development, particularly through local participation in redevelopment planning and institutional cooperation, is the central issue of the review. Previous research and past assumptions about the process by which communities rebuild after a disaster are reviewed. A conceptual model for understanding local disaster recovery efforts is then presented. The conceptual and practical significance of this model is then demonstrated by presenting case studies of local recovery experiences. Finally, conclusions on the current understanding of disaster redevelopment planning, as well as implications for public policy and future research are offered (AU)

The feasibility of vertical evacuation : Behavioral, legal, political, and structural considerations

The risk posed by hurricanes striking the coastal of the United States is significant and rising. Because of rapid population growth and insufficient new road construction along coastal areas, there exists a great potential for enormous loss of life. For some coastal areas it is already possible for the evacuation time to exceed accurate warning times. For example, in Galveston, Texas, the impending landfall of a Category 4 or 5 hurricane (131 mph or greater) would require total evacuation of the area, which is estimate to take 26 hours, while state-of-the-art forecasting techniques are capable of giving reliable predictions of strike location 12 hours before landfall.(AU)

Influences on local adoption of planning measures for earthquake hazard mitigation

This article assesses the extent to which various planning measures are used by communities for mitigating earthquakes hazards. A secondary aim is to examine how planning process activities and community context characteristics influence local adoption of planning measures for mitigation. A number of conclusions based on data from a national survey of communities are risk to earthquakes were derived. Communities use a wide variety of planning measures for earthquake mitigation, but the frequency of adoption of such measures was greater in California than in other states. Planning process activities had a more important influence on local adoption than context characteristics. This conclusion implies that local efforts to advance local earthquake mitigation programs have a substantial potential for success. This paper examines local government planning efforts aimed at earthquake hazard mitigation. Utilizing data from a national survey, we focus on how planning process activities and community context characteristics influence local adoption of planning measures; e.g., land use regulations and development controls. More specifically, we seek to address the following three questions: first, to what extent have various planning measures been adopted for earthquake hazard mitigation? Second, what is the relative importance of process activities compared to context characteristics? third, to what degree do factors that influence adoption differ between communities in California, and those in other states?
