This research investigates community exposure to coastal climate hazards in Alaska?s North Slope and incorporates community assessment of the potential effects on loss of land, infrastructure, and other assets. This analysis will inform response strategies and planning by developing new methods of hazard assessment that can support community resilience in the North Slope and potentially serve as a model for advancing assessment and planning in other rural and urban communities. This research will expand traditional assessments of financial exposure to also include non-material factors such as values and priorities of diverse social groups within a community including a diverse set of stakeholders, ranging from multinational oil companies to individual subsistence hunters. This study surveys community views of asset importance and integrates results with a geophysical hazard data model for a coproduced community exposure map of the North Slope coast. This research will contribute to understanding the human and social dimensions of climate change impacts, including how social, economic, political, and cultural factors shape vulnerabilities and condition response strategies. Methods and findings could enhance nation-wide efforts in the United States to map community exposure to coastal climate hazards by demonstrating methods for, and the importance of systematically incorporating non-market values in exposure analysis.The objectives of the proposed research include adapting the U.S. Geological Survey's (USGS) coastal vulnerability index (CVI) to the Arctic context, and integrating results with formal asset databases and a spatial community landscape value model while working with affected communities during the process to coproduce exposure maps. Specifically, working with North Slope Alaskan communities the study will incorporate wind fetch (i.e., the open water distance over which wind can generate near shore waves, determined by sea ice extent) into the CVI and get community feedback on the results. In addition to community input on the CVI maps, coproducing the exposure maps includes the community assigning values to traditional land use places using existing spatial datasets and mapping and investigating specific sites threatened by coastal hazards with the aim to learn why exposed assets threaten the community.

这项研究调查了社区对阿拉斯加北坡沿海气候危害的接触，并纳入了社区对土地，基础设施和其他资产损失的潜在影响的评估。该分析将通过开发新的危害评估方法来为响应策略和计划提供依据，这些方法可以支持北坡的社区弹性，并有可能作为推进其他农村和城市社区评估和计划的模型。这项研究将扩大对财务风险的传统评估，还包括非物质因素，例如社区内的价值观和各种社会群体的优先事项，包括一组各种利益相关者，从跨国石油公司到个人生活猎人。这项研究调查了社区对资产重要性的看法，并将结果与​​地球物理危害数据模型相结合，以构成北坡海岸的社区暴露地图。这项研究将有助于理解气候变化影响的人类和社会层面，包括社会，经济，政治和文化因素如何塑造脆弱性和条件反应策略。 方法和发现可以加强美国在全国范围内的努力，以通过证明方法来映射社区接触沿海气候危害，并系统地将非市场价值纳入暴露分析中的重要性。拟议的研究的目标包括调整美国地质调查局（USGS）海岸脆弱性范围（CVI）和整合弧形的范围，并将其整合到境界，并集成了境界，并将其整合到弧形上，并集成了境界，并将其整合起来。在此过程中与受影响社区合作的同时建模，以相互曝光图。具体而言，与北坡阿拉斯加社区合作，研究将结合风（即，风能在海岸波（由海冰范围决定）附近产生的开放水距离）进入CVI，并就结果获得社区反馈。除了在CVI地图上的社区投入外，曝光图还包括社区使用现有的空间数据集为传统的土地利用场所分配价值，并绘制和调查受海岸危害威胁的特定地点，以了解为什么暴露资产威胁社区。
