Key Priorities and University Roles to Address Coastal Resilience in Virginia: Findings from the Rotating Resilience Roundtables Workshop Fall 2018
From Part 1. Purpose and significance
The first Rotating Resilience Roundtables event took place on October 11 and 12, 2018 on the Virginia Tech campus in Blacksburg and was co-organized between the Coastal@VT initiative at Virginia Tech and Old Dominion University/Virginia Sea Grant Climate Adaptation and Resilience Program. It was designed to respond to the need for a cohesive and policy-relevant science that will align and coordinate efforts between researchers and other stakeholders to benefit the Commonwealth’s resilience planning for changing conditions in coastal zone. The Rotating Roundtables’ concept was selected to facilitate active engagement of audiences with different coastal themes, as well as to stimulate problem identification, critical thinking, and alignment between the real-time issues and research questions
Fostering University Collaboration and Building Capacity to Respond to Coastal Resilience Challenges in Virginia: Findings from the Rotating Resilience Roundtables Workshop Spring 2019
[from Background and Overview]
Communities in coastal Virginia, particularly in the urban region of Hampton Roads and the rural Eastern Shore peninsula, are experiencing the impacts of climate change as part of everyday life. Among the most apparent impacts are sea level rise and associated flooding, but increasingly residents of the region are observing changing ecosystems, health impacts and complex social challenges are made more difficult. The region is experiencing the fastest rate of relative sea level rise on the U.S. east coast due to interactions between ocean currents, global sea level rise, high-water tables and ground subsidence (Adapt Virginia 2019; Atkinson et al. 2013). Emergency managers are having to deal with more severe storms due to increased intensity of rainfall (Smirnov 2017). While building resilience to sea level rise and flooding has become an important priority for many local governments in Hampton Roads, the Commonwealth has also recognized the importance of coastal resilience, and in 2018 appointed Rear Admiral Ann Phillips as Special Assistant to the Governor for Coastal Adaptation and Protection. As local, regional and state-wide governments plan for climate change, universities will play a key role in the integration of intellectual capacities and knowledge to address coastal resilience in the Commonwealth
A Systematic Review of Coastal Vulnerability Mapping
Coastal areas worldwide represent an aggregation of population and assets of growing economic, geopolitical, and sociocultural significance, yet their functions are increasingly challenged by worsening coastal hazards. Vulnerability assessments have been recognized as one way we can better understand which geographic areas and segments of society are more susceptible to adverse impacts from different stressors or hazards. The aims of this paper are to evaluate the state of coastal vulnerability assessment mapping efforts and to identify opportunities for advancement and refinement that will lead to more cohesive, impactful, and policy-relevant coastal vulnerability studies. We conducted a systematic review of the literature that addresses physical and social vulnerability to coastal hazards and contains corresponding mapping products. The content was analyzed for the scale of analysis, location, disciplinary focus, conceptual framework, metrics used, methodological approach, data sources, mapping output, and policy relevance. Results showed that most Coastal Vulnerability Mapping Assessments (CVMAs) are conducted at the local level using a range of methodologies, often with limited inclusion of social considerations and limited discussion of policy relevance. Based on our analysis, we provide seven recommendations for the advancement of this field that would improve CVMAs’ methodological rigor, policy relevance, and alignment with other vulnerability assessment paradigms
Anticipating and Adapting to the Future Impacts of Climate Change on the Health, Security and Welfare of Low Elevation Coastal Zone (LECZ) Communities in Southeastern USA
Low elevation coastal zones (LECZ) are extensive throughout the southeastern United States. LECZ communities are threatened by inundation from sea level rise, storm surge, wetland degradation, land subsidence, and hydrological flooding. Communication among scientists, stakeholders, policy makers and minority and poor residents must improve. We must predict processes spanning the ecological, physical, social, and health sciences. Communities need to address linkages of (1) human and socioeconomic vulnerabilities; (2) public health and safety; (3) economic concerns; (4) land loss; (5) wetland threats; and (6) coastal inundation. Essential capabilities must include a network to assemble and distribute data and model code to assess risk and its causes, support adaptive management, and improve the resiliency of communities. Better communication of information and understanding among residents and officials is essential. Here we review recent background literature on these matters and offer recommendations for integrating natural and social sciences. We advocate for a cyber-network of scientists, modelers, engineers, educators, and stakeholders from academia, federal state and local agencies, non-governmental organizations, residents, and the private sector. Our vision is to enhance future resilience of LECZ communities by offering approaches to mitigate hazards to human health, safety and welfare and reduce impacts to coastal residents and industries
The role of proximity to waterfront in residents’ relocation decision-making post-Hurricane Sandy
The experience with Superstorm Sandy advanced the dialogue on the long-term response options that would minimize risks and ensure livability in high-risk coastal environments. One strategy considered permanent relocation of homes from flood-prone areas. However, little is known about the factors that might influence a homeowner\u27s decision to relocate, how their home\u27s proximity to the shoreline may affect their risk perceptions and willingness to relocate. This paper explores the role that proximity to the oceanfront plays in relocation decision-making. It examines geospatial determinants collected as a part of a 2013 household survey conducted post Hurricane Sandy and their relationship with survey responses and socioeconomic predisposition. The analysis uses geospatial data to assess the proximity attributes of participating households. The proximity parameters were statistically compared to the socioeconomic profile and survey responses. The results demonstrate that the location of surveyed households, even though adequately dispersed to the oceanfront proximity, had only a minor effect on the willingness to relocate, suggesting that non-geophysical factors, such as household-level confidence in the ability to adapt and continue habitation in such locations, values, and other qualitative personal factors play a larger role. The findings also show that participants living closer to the bay are more likely to consider relocation if exposed to repetitive flooding and offered participation in buyout program
Aging in Flood-Prone Coastal Areas: Discerning the Health and Well-Being Risk for Older Residents
Coastal communities are increasingly exposed to more intense and frequent hurricanes, accelerated sea-level rise, and prolonged tidal inundation, yet they are often a preferred retirement destination for older adults vulnerable to flooding and extreme weather events. The unique physical and psychosocial challenges of older population age 65 and over may affect their level of preparedness, capacity to cope with, and ability to respond and recover from a hazard event. Despite the clear vulnerabilities of older residents living in high-risk areas when compared to younger coastal populations, there is a lack of empirical research on the integrated flood risks to this population group in the coastal context. This paper provides a holistic assessment of this emerging problem along the U.S. East Coast by measuring the exposure of older population to sea level rise and storm surge in coastal counties. It further evaluates how age-related vulnerabilities differ between rural and urban settings using the case study approach and geospatial and statistical analysis the paper also conducts a review of scientific literature to identify gaps in the current understanding of health and well-being risks to aging populations in coastal communities. The results show that older populations are unevenly distributed along the U.S. East Coast with some states and counties having significantly higher percent of residents age 65 and older living along the shoreline. Many places with larger older populations have other attributes that further shape the vulnerability of this age group such as older housing stock, disabilities, and lower income and that often differ between rural and urban settings. Lastly, our study found that vast majority of research on aging in high-risk coastal locations has been conducted in relation to major disasters and almost none on the recurrent nuisance flooding that is already affecting many coastal communities
Socio-Ecological Mobility: A Research Strategy for a New Coastline
Persistent development, population pressures, and increasing natural hazards are unequivocally changing socio-ecological systems in the coastal zone. This essay provides direction and initiates scientific dialog on the potential role of mobility in adapting to natural and social changes in coastal environments. The essay identifies four key research areas on information needed to develop coastal management actions and policies that support and recognize socio-ecological coupling in coastal areas. The proposed research includes: (1) modeling localized scenarios that illustrate the tradeoffs associated with various sea level rise adaptation, (2) assessing and consolidating mobility terminology for different applications and contexts, (3) developing solutions to synchronize the co-migration of natural environments and built infrastructure, and (4) evaluating existing or creating new transparent, equitable, and sustainable policies and incentives to support socio-ecological mobility by using case studies and social science methods to understand how people make mobility decisions in different contexts
