Urban areas account for around 50% of global solid waste generation. In the last decade, the European Union has supported numerous initiatives aiming at reducing waste generation by promoting shifts towards Circular Economy (CE) approaches. Governing this process has become imperative. This article focuses on the results of a governance analysis of six urban regions in Europe involved in the Horizon 2020 project REPAiR. By means of semi-structured interviews, document analysis and workshops with local stakeholders, for each urban area a list of governance challenges which hinder the necessary shift to circularity was drafted. In order to compare the six cases, the various challenges have been categorized using the PESTEL-O method. Results highlight a significant variation in policy contexts and the need for these to evolve by adapting stakeholders’ and policy-makers’ engagement and diffusing knowledge on CE. Common challenges among the six regions include a lack of an integrated guiding framework (both political and legal), limited awareness among citizens, and technological barriers. All these elements call for a multi-faceted governance approach able to embrace the complexity of the process and comprehensively address the various challenges to completing the shift towards circularity in cities.

Circular economy (CE), the new ‘buzzword’ in urban and regional studies and policy debates, is about shifting from a linear production process towards a circular one in which the generation of waste is minimised, materials circulate in ‘closed loops’, and waste is not considered a burden but rather a resource that brings new economic opportunities. However, while there is a consensus on the need to facilitate a transition towards a circular economy, the governing of this endeavour remains extremely challenging because making a circular economy work requires cutting across sectoral, scalar, and administrative boundaries. Drawing on the sustainability transitions literature and the case of the Amsterdam Metropolitan Area, arguably one of the frontrunners on the strive towards a circular built environment and economy, the paper seeks to identify and understand barriers for CE transition at a regional scale. The findings underscore the multi-faceted nature of the challenge and offer lessons for the governance of emerging regional circular spatial-economic policies.

To understand and deal with real urban development problems, urban planners, designers, and managers need to combine and synthesize a variety of academic and professional knowledge. As our urban challenges grow more complex, learning how to do this effectively becomes ever more important. For educators, this means teaching students how to work in interdisciplinary settings, i.e. how to jointly discover the different disciplinary dimensions of an urban problem, and how to reflectively design courses of action. In this paper, we explore and evaluate the components of such interdisciplinary experiential learning, develop a framework to design and analyse this type of courses, and use it to position and evaluate a specific urban development management course. Results show that, by performing and reflecting upon specific professional roles, the course stimulates students to both integrate different disciplines and reflect on an array of academic and practical insights. Based on our evaluation, we discuss several didactical aspects that may help lecturers to improve their interdisciplinary teaching in urban planning, design, and management courses—particularly when creating learning experiences in an increasingly diverse professional, societal and educational setting.

Dutch planning practice in recent decades witnesses the emergence of private sector-led urban development projects. Such projects are ‘led’ by property developers and ‘facilitated’ by local planning authorities aimed to realize both planning and market objectives. However, remarkably little academic attention has been paid to how public and private actors decisively organize and manage these projects in practice. This paper explores the roles planners and developers perform by generating empirical lessons from Dutch and UK planning practices. The findings are of importance to planners and planning theory, as the current social-economic circumstances require them to redefine their roles in urban development.

The aim of this paper is to better understand the dynamics of circular construction projects and how these interorganizational projects contribute to the transition towards a circular economy. It is essential that the construction sector develops and adopts interorganizational initiatives to support the transition to a circular and low-carbon construction economy. A benefit of being involved in such initiatives is that organizations reflect on the emergence and acceptance of new practices related to changing organizational roles and responsibilities. In this paper, we study eight circular construction projects within the context of an interorganizational initiative to stimulate the transition towards a circular economy by exploring insights from evaluations thereof. We build upon literature from Sustainability Transitions Research (STR), circular construction research, and interorganizational project studies. Our findings show three clusters of dynamics that are relevant in the realization of circular ambitions in interorganizational construction projects: (1) prerequisites, (2) temporal dynamics in interorganizational projects, and (3) contextual influences. These insights highlight factors that enable the realization of circular ambitions in construction projects and contribute to our understanding of the dynamics of interorganizational construction projects and their role in the context of STR.

At a time of public sector retrenchment in urban regeneration it has become increasingly important to understand how planners can help create better places. Recent studies suggest that planners must behave as market actors by strategically deploying planning tools to influence market behaviour. In this context, this paper examines how local planning authorities use a variety of policy instruments to influence urban projects and turn planning strategies into action. To understand how planning tools can be used to achieve successful results in urban regeneration practice, the paper presents a cross-comparison of mixed-use city centre regeneration projects in Bristol and Liverpool.
