摘要：AbstractThis paper highlights challenges and open questions pertaining to physical and social infrastructure system interdependencies and their implications for disaster response, recovery, and resilience planning efforts. We describe the importance of understanding interdependencies in disaster contexts and highlight limitations to existing approaches. Suggestions for understanding and addressing interdependencies focus on increasing availability of tools for assessing interdependencies and increasing stakeholder and decisionmaker uptake of infrastructure interdependency‐related information in planning efforts.Plain Language SummaryInterdependent physical and social systems offer enormous benefits for daily life because they produce and distribute essential goods and services that are necessary for health, safety, and economic well‐being. For instance, the power grid is required for effective functioning of information systems and cell phones, which underpin effective functioning of hospitals, water and sewer systems, traffic lights, and home appliances. In return, communications and information technology is required for effective functioning of the power grid, especially to meet the concurrent demands for reliable energy supply, protection, and automation. In this paper, we describe how failure in interdependent systems can be catastrophic and lead to death and prolonged human suffering. We examine difficulties in linking failures in interdependent systems to measurable social impacts including: limited availability of data and models, disciplinary silos that might stand in the way of different stakeholders, practitioners, and experts working together on this inherently cross‐disciplinary problem, and diversity in infrastructure systems, disruptive events, and communities. We suggest that awareness of the vulnerabilities in interdependent infrastructure systems needs to be coupled with coordinated action and collaboration among government agencies, communities, and industries.Key PointsLimited data and models and disciplinary silos make it difficult to link failures in interdependent infrastructures to social outcomesAwareness of infrastructure vulnerabilities needs to be coupled with coordinated action among government, communities, and industriesWe suggest ways to improve understanding of interdependencies and increase stakeholder uptake of relevant information in planning efforts
