Closing integrative gaps in complex environmental governance systems

Modern environmental problems pose unique management challenges as they are usually interdependent in myriad,complex ways. Climate change is the ultimate example of a problem that forces environmental managers to confront highlyinterdependent challenges, such as invasive species, rising temperatures, and habitat loss. Interdependencies abound: for example, theissue of warming winter temperatures exacerbates the issue of invasive species, and a high prevalence of invasive species contributesto the issue of habitat loss. Ideally, stakeholders should account for these issue interdependencies by managing connected issues. Suchactivities close "integrative gaps," which refer to instances in which interdependent issues are managed independently. By closingintegrative gaps, actors align management activities with underlying ecological processes. We focus on climate change adaptationgovernance in Ohio, USA, as a model study system and evaluate conditions that enable integrative gap closure through analysis of anetwork of adaptation actors and issues. Our findings show that actors are more likely to close integrative gaps between issue pairsthat are highly biophysically interdependent, receive higher collective levels of public attention, and have garnered higher levels ofprogress. We also find that regional-scoped, specialized, and non-profit actors are most likely to manage for environmentalinterdependencies. We discuss how these findings advance theoretical understanding of institutional fitness and resilience in social-ecological systems by revealing how actors navigate highly interdependent environmental governance settings.
