Ingredients for a more radical strategic spatial planning

The purpose of the paper is to contribute to the debate on existing planning approaches-more specifically, strategic spatial planning-and the search for new ideas. Therefore, after briefly dealing with the history, logic, aims of strategic planning, and some critiques the paper sketches the contours of a more radical strategic planning, introduces coproduction as a corner stone of this approach, and opts for working with conflicts and legitimacy as additional building blocks. The paper relies on a selective review of critical planning literature and the authors' experience in practice.
