Enhancing Coastal Resilience through Participatory Transformation of Barrier Islands

由于海平面上升和更强的风暴，屏障岛屿社区面临洪水，典型的适应措施（保护、适应、撤退）可能跟不上日益增加的风险。社区现在正在考虑极端的适应措施，例如通过拆除道路和其他基础设施，让岛屿部分“回归自然”。但这些极端的适应改变了自然过程以及社区与障碍的关系。对附近社区洪水风险的影响尚不清楚，也不清楚社区是否会“欢迎水”或拒绝它，因为它违背了他们的地方感。这个灾难恢复力研究补助金（DRRG）项目探讨了参与性的障碍改造。利益相关者将提供关于屏障岛上的地方意义的见解，以及洪水如何影响这些地方及其与社区的联系。该项目还量化了自然岛屿部分的洪水如何改变邻近社区的危险，以及是否可以选择这些位置以最大限度地减少风险，同时最大限度地增加社区附件。这些活动为参与式转型提供了一个框架，并为洪水风险建模提供了先进的技术，这些技术可以扩展到提高美国沿着海湾和大西洋沿岸社区的抗灾能力。这项研究还支持沉浸式的经验，为学生跨工程和社会科学学科的合作，以应对气候变化的挑战。这个灾难恢复力研究资助项目推进当地侵蚀事件如何导致邻近社区的洪水的理解;这些洪水如何可以通过允许屏障部分回归自然来管理;以及这种转变在社区利益相关者的知情和审议下，如何影响社区场所的意义。研究将围绕以下目标组织：（O 1）确定屏障系统极端适应的“可接受”地点;（O2）量化“可接受”和其他地点极端适应造成的洪水风险降低;（O3）评估利益攸关方对屏障岛屿极端适应技术的看法变化。通过对可能的障碍配置和未来气候情景下的洪水进行高分辨率建模，该项目量化了邻近社区的洪水规模。通过科学合作生产，该项目调查了如果利益相关者在改造中发挥积极作用，社区对屏障岛的依恋如何增加。该项目使用变革性研究方法和参与，以促进社区主导的管理和适应障碍的新方法，使更好的努力规划地貌变化和发展的后果，并促进沿海科学，工程，该奖项反映了NSF的法定使命，并被认为是值得通过评估使用基金会的知识优点和更广泛的影响审查标准。

Barrier-island communities face flooding due to rising sea levels and stronger storms, and typical adaptations (protect, accommodate, retreat) may not keep up with increasing risks. Communities are now considering extreme adaptations, such as allowing an island section to ‘return to nature’ by removing roadways and other infrastructure. But these extreme adaptations transform the natural processes of and the community’s relationship with barriers. The effects on flood risks at nearby communities are not well understood, and it is not clear whether communities will ‘welcome the water’ or reject it as opposing their sense of place. This Disaster Resilience Research Grant (DRRG) project explores participatory transformation of barriers. Stakeholders will provide insights on place meanings across the barrier island and how floods affect these places and their connections to the community. The project also quantifies how flooding at a natural island section may change the hazard at neighboring communities, and whether these locations can be selected to minimize the risks while maximizing community attachments. These activities provide a framework for participatory transformation, as well as advance technologies for flood risk modeling that can be expanded to improve disaster resilience for communities along the U.S. Gulf and Atlantic coasts. This research also supports an immersive experience for students to collaborate across engineering and social-science disciplines to tackle the challenges of climate change.This Disaster Resilience Research Grant project advances understanding of how local erosion events contribute to floods at neighboring communities; how these floods can be managed by allowing barrier sections to return to nature; and how such a transformation, when informed and deliberated by community stakeholders, may affect community place meanings. The research will be organized on the following objectives: (O1) identify ‘acceptable’ locations for extreme adaptation of barrier systems; (O2) quantify reductions in flood risk from extreme adaptations at ‘acceptable’ and other locations; and (O3) assess changes in stakeholders’ perceptions about extreme adaptation techniques for barrier islands. Via high-resolution modeling of flooding subject to possible barrier configurations and future climate scenarios, this project quantifies the scales of flooding at neighboring communities. And via science co-production, this project investigates how the community’s attachment to the barrier island may be increased if stakeholders take an active role in the transformation. This project uses transformative research approaches and engagement to facilitate new approaches to community-led management and adaptation of barriers, enable improved efforts to plan for the consequences of landform changes and development, and advance the integration of the coastal science, engineering, and adaptation disciplines.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
