In order to implement a sustainability turn, a fundamental rethinking of normative orientations, instruments and ways of doing spatial planning is required. Changing the established framework of one's own thinking also requires changing the perspective, because previous points of view and known approaches have not led to satisfactory solutions. Not only the objectives and outcomes of planning, but also the way to get there have to be reconsidered.

The planning theory track discusses theory-based approaches for the description, explanation and conception of a changing planning for sustainable development. The focus is on changed spatial policies, actor and governance arrangements as well as new forms of communication and participation. In addition, it is important to reflect the planning contributions for sustainable spatial development in terms of planning theory and to analyze the values ​​and orientations behind it.

We welcome contributions that empirically and analytically reflect the change in planning by means of case studies and aim at a better understanding of planning practice, as well as those that focus on conceptual approaches for the further development of planning theories and thus indirectly on guidelines for planning practice.

Possible topics include:

• Legitimacy and rationality of planning for sustainable spatial development
• New actor and governance arrangements
• Planning contributions to sustainability
• Strategic planning and emergence
• Change of planning cultures
• Alternative theories in and of planning
