Interdependent Infrastructure as Linked Social, Ecological, and Technological Systems (SETSs) to Address Lockāin and Enhance Resilience
Traditional infrastructure adaptation to extreme weather events (and now climate change) has typically been technoācentric and heavily grounded in robustnessāthe capacity to prevent or minimize disruptions via a riskābased approach that emphasizes control, armoring, and strengthening (e.g., raising the height of levees). However, climate and nonclimate challenges facing infrastructure are not purely technological. Ecological and social systems also warrant consideration to manage issues of overconfidence, inflexibility, interdependence, and resource utilizationāamong others. As a result, technoācentric adaptation strategies can result in unwanted tradeoffs, unintended consequences, and underaddressed vulnerabilities. Technoācentric strategies that lockāin today\u27s infrastructure systems to vulnerable future design, management, and regulatory practices may be particularly problematic by exacerbating these ecological and social issues rather than ameliorating them. Given these challenges, we develop a conceptual model and infrastructure adaptation case studies to argue the following: (1) infrastructure systems are not simply technological and should be understood as complex and interconnected social, ecological, and technological systems (SETSs); (2) infrastructure challenges, like lockāin, stem from SETS interactions that are often overlooked and underappreciated; (3) framing infrastructure with a SETS lens can help identify and prevent maladaptive issues like lockāin; and (4) a SETS lens can also highlight effective infrastructure adaptation strategies that may not traditionally be considered. Ultimately, we find that treating infrastructure as SETS shows promise for increasing the adaptive capacity of infrastructure systems by highlighting how lockāin and vulnerabilities evolve and how multidisciplinary strategies can be deployed to address these challenges by broadening the options for adaptation
