Transitions in planning: transformative policy visions of the circular economy and blue bioeconomy meet planning practice

Ongoing sustainability challenges create pressure on planning practices and institutional arrangements. Transformative policy visions, such as the circular economy and bioeconomy, create promises for designing and planning sustainable pathways in society. Moreover, research agendas on sustainability transitions, such as transition management, are developing toolkits and attempting to shift planning practice by applying evidence-based policy-making processes. In this paper, we ask what happens when sustainability visions are exposed to planning practices, and vice versa, by developing an analytical framework to discuss processes of territorialization and mobilization. We draw lessons from two contextually differing case studies in Finland; on the evaluation of spatial planning processes for the circular economy and a strategic planning intervention for the blue bioeconomy. The disparate cases show that the planning process act as a bidirectional intermediary space, refining both the general transition visions and established planning practices.
