Abstract
While research into the nexus has expanded significantly, few studies have sought to theorize its governance. By adopting a policy instruments perspective, this chapter therefore initially examines how the nexus is emerging at different scales and national contexts worldwide. Empirical evidence of policy instrument innovation is then analyzed using conventional governance theories to argue that the holistic nature of the nexus concept requires new theorizing to interpret this emerging reality. Normative suggestions for theorizing future nexus governance are also forwarded.
