Doctoral Dissertation Research in DRMS: Resilience for Whom: A Climate Mobility Framework for Evaluating Equity Outcomes in Climate Resilience Decision Making

海平面上升正在增加极端海平面事件，包括与涨潮和风暴相关的洪水，这将推动沿海社区居民的迁移和流离失所。最近的研究主要集中在气候驱动的迁移和流离失所的宏观经济影响上，但在我们对气候相关运动的多样性或特定地区的气候流动的理解上仍然存在很大的研究差距。流动性考虑包括沿海社区内部的社会和经济差异，这些差异可能会阻碍居民应对气候迁移结果的能力。目前迫切需要了解气候迁移的局部动态，以强调在海平面上升适应规划中的公平考虑。本研究的目的是通过创建一个新的气候流动框架，研究海平面上升相关暴露风险和社会经济脆弱性的交集，以及它们对未来潜在气候移民结果的综合影响。气候流动性框架区分了稳定、迁移、流离失所和被困的四组社区，以评估在高度不确定性和对资金的社会需求相互竞争的情况下，适应海平面上升规划中潜在的不平等。本研究有三个主要目标：(1)开发一个概念框架，考虑海平面上升相关运动的多样性；(2)通过混合方法，包括空间分析和通过访谈和调查收集原始数据，在佛罗里达州迈阿密-戴德县的现有居民中测试该框架；(3)促进与政府官员和社区领导人的合作进程，以了解该框架如何促进未来气候适应政策的公平决策。本研究采用可公开访问的数据集，如美国人口普查美国社区调查，以开发脆弱性的社会经济指标，并整合新的暴露风险措施，如并行光栅淹没模型，或PRIMo，它提供高分辨率的区域复合洪水评估，以进行强有力的决策。气候流动性框架应可转移到美国沿海社区和其他存在产权和土地使用权的社会。从这项研究的各个阶段得出的结论和提出的解决方案可能与全球沿海社区有关。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Sea level rise is increasing extreme sea level events, including high-tide and storm-associated floods, which will drive migration and displacement of residents within coastal communities. Recent studies have focused on the macro-economic implications of climate-driven migration and displacement, but there remains a large research gap in our understanding of the multiplicities of climate related movement, or climate mobilities within a given locality. Mobility considerations encompass the social and economic disparities within coastal communities that may impede the ability of residents to cope with climate migration outcomes. There is a pressing need to understand local dynamics of climate migration as experienced across the spectrum of vulnerability to highlight equity considerations in sea level rise adaptation planning. The purpose of this research is to examine the intersection of sea level rise related exposure risk and socio-economic vulnerability and their combined impact on potential future climate migration outcomes through the creation of a novel climate mobility framework. The climate mobility framework distinguishes between four sets of communities - stable, migrating, displaced, and trapped- to assess potential inequities within sea level rise adaptation planning given deep uncertainty and competing societal demands for funding. This research has three primary objectives: (1) develop a conceptual framework that considers the multiplicities of sea level rise related movement, (2) test this framework among current residents of Miami-Dade County, FL though a mixed methods approach that includes spatial analysis and primary data collection through interviews and surveys, and (3) facilitate a process of co-production with government officials and community leaders to understand how the framework can advance equitable decision making for future climate resilience policy. This research employs publicly accessible datasets such as the U.S Census American Community Survey to develop socio-economic indicators of vulnerability, and integrates novel measures of exposure risk such as the Parallel Raster Inundation Model, or PRIMo, which provides high resolution regional compound flooding assessments for robust decision making. The climate mobility framework should be transferable to coastal communities in the United States and other societies where property rights and land-use tenure exist. The conclusions and proposed solutions that emerge from all phases of this research are likely to be relevant for coastal communities globally.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.
