Spatial planning and policy integration: Concepts, facilitators and inhibitors

While the concept of policy integration is not a new idea within spatial planning discourse, it is becoming increasingly prevalent. Frequently, however, the term is used without any clear definition of what it means, or how it might be achieved. The aim of this paper is to provide more clarity about the concept and to identify the types of actions in the field of planning where integration with policy can be improved. In so doing, the paper assembles a range of material from different disciplines, and identifies some of the key inhibitors and facilitators of policy integration.
