适应环境变化已成为许多北极社区的必要性和常态。我们使用北极水资源脆弱性指数（AWRVI）来研究阿拉斯加不同社区的适应能力是否存在差异，并对比生态和社会经济系统。我们将该指数应用于阿拉斯加三个不同地区的六个社区的水资源：阿拉斯加北部的努伊克苏特、阿拉斯加中南部基奈河流域的库珀兰丁、斯特林、索尔多特纳和基奈以及阿拉斯加东南部的朱诺。我们修改了 AWRVI 工具，以适应这些社区的广泛的物质和社会条件。我们使用 AWRVI 测量了社区的适应能力，这反映了阿拉斯加北部努伊克苏特地区由于供水限制和周边开发可能污染其食物棚内的水而更加脆弱。库珀兰丁 (Cooper Landing) 和朱诺 (Juneau) 这两个山区较多的社区的整体适应能力相似，斯特林 (Sterling)、索尔多特纳 (Soldotna) 和基奈 (Kenai) 的整体适应能力也相似，这三个社区位于基奈河 (Kenai River) 沿岸，地势较为平坦。然而，基奈河流域和朱诺社区的物质和社会分指数有所不同。我们讨论每个社区可以采取的行动，以提高各自应对预期变化的能力。
Adaptation to environmental change has become a necessity and a norm for many Arctic communities. We examine whether the adaptive capacity varies in different communities in Alaska with contrasting ecologies and socio-economic systems using the Arctic Water Resources Vulnerability Index (AWRVI). We applied the index to six communities in three distinct regions of Alaska with respect to water resources: Nuiqsut in Northern Alaska, Cooper Landing, Sterling, Soldotna and Kenai in the Kenai River watershed of Southcentral Alaska and Juneau in Southeast Alaska. We modified the AWRVI tool to accommodate the breadth of physical and social conditions in these communities. Using the AWRVI, we measured the adaptive capacity of the communities, which reflect greater vulnerability in Nuiqsut in Northern Alaska due to limitations in water supply and greater surrounding development that could pollute water in their food-shed. The overall adaptive capacities of the two communities that are more mountainous, Cooper Landing and Juneau are similar, as are Sterling, Soldotna and Kenai’s, which are in flatter terrain along the Kenai River. However, the physical and social sub-indices of the communities in the Kenai River watershed and Juneau differ. We discuss actions each community could take to improve their respective capacity to respond to anticipated change.
