A marriage of inconvenience the coupling of spatial planning to European environmental policy

For decades, the European Union has affected spatial planning in the member states through its environmental policies. To investigate the mechanism by which EU policy becomes joined up to spatial planning, we invoke the concept of ‘coupling’ from systems and organizational science. We show that coupling is established not only at the EU policymaking level (e.g. within a directive’s text), but also during implementation and enforcement. Consequently, it is possible to actively ‘manage’ coupling either by enhancing its flexibility on paper or by limiting its activation in practice. Drawing on three case studies in the Netherlands, we show that various (de)coupling strategies can be applied, but none are completely satisfactory or risk-free.
