Adaptation planning and evaluation is challenging because adaptation is occurring on complex systems that are not completely understood. Though assessment is more straightforward for single projects, the larger question often asked is whether multiple adaptation actions, developed by different actors and for different purposes, are making a region more resilient. One way to comprehensively assess adaptation is through indicators—a promising decision support tool because they can be designed to efficiently and comprehensively summarize system behavior even if significant uncertainty exists. In practice, choosing indicators requires navigating a rich and often contradictory information landscape of peer-reviewed and non-peer reviewed documents and data products, largely produced for other purposes. In this paper, we review the available information applicable to resilience indicators for the Chesapeake Bay region of the USA. To provide consistency across such diverse projects and information sources, we develop a resilience framework through literature and stakeholder engagement that provides a consistent definition of objectives and frame for evaluation. Using systematic search methods, we identified 283 relevant documents, which were then qualitatively assessed for climate change and resilience themes. Predominant themes emerge around key regional impacts—sea level rise, water quality, flooding, and aquatic ecosystems—as well as magnitude of, exposure to, and impacts of climate hazards. Notably, relatively little information was found for designing indicators for coping and adaptive capacity and adaptation responses. This result highlights that even for well-known problems in the Chesapeake Bay region, much work remains in translating the existing information landscape into actionable indicators.

适应计划和评估具有挑战性，因为适应发生在尚未完全理解的复杂系统上。尽管对单个项目的评估更为直接，但经常提出的更大问题是，由不同行为者制定并针对不同目的采取的多种适应行动是否正在使该地区更具弹性。一种全面评估适应性的方法是通过指标-一种有前途的决策支持工具，因为即使存在重大不确定性，也可以将其设计为有效，全面地总结系统行为。在实践中，选择指标需要浏览经过同行评审和未经同行评审的文档和数据产品的丰富且通常相互矛盾的信息格局，这些文档和数据产品主要用于其他目的。在本文中，我们将审查适用于美国切萨皮克湾地区弹性指标的可用信息。为了在各种项目和信息源之间提供一致性，我们通过文献和利益相关方的参与建立了弹性框架，为目标和评估框架提供了一致的定义。我们使用系统的搜索方法，确定了283份相关文件，然后就气候变化和抗灾力主题进行了定性评估。围绕主要区域影响（海平面上升，水质，洪水和水生生态系统）以及气候危害的程度，暴露和影响，围绕着主要主题出现。值得注意的是，发现用于设计应对能力和适应能力以及适应反应指标的信息很少。
