This study evaluates the capacity of local authorities in Khobar, Saudi Arabia, to implement participatory urban planning within a centralized governance system and the context of Vision 2030 reforms. It introduces a conceptual framework structured around four key dimensions: transparency, public participation, responsiveness, and technology adoption. Drawing on a mixed-methods approach—including 20 semi-structured interviews with officials and survey data from 453 residents—the research identifies institutional and systemic barriers, such as bureaucratic inefficiencies, overlapping mandates, and the symbolic use of participatory mechanisms in urban planning. While e-platforms like Istitlaa and Balady offer digital avenues for participation, their impact remains constrained by digital inequality and limited integration with decision-making. The findings also reveal that public input often informs minor project adjustments rather than shaping strategic planning, highlighting the consultative rather than collaborative nature of participatory urban planning in Khobar. This paper contributes to participatory governance theory by adapting Arnstein’s Ladder to assess participation levels in centralized, non-democratic contexts. It demonstrates that while reforms under Vision 2030 have encouraged decentralization and public participation, significant gaps persist in institutional transparency, responsiveness, and the effective use of participatory tools. To enhance participatory outcomes, the study proposes targeted reforms, including institutionalizing participatory frameworks, improving inter-agency coordination, and investing in digital and human capacity. The findings offer broader implications for implementing participatory planning in transitional governance systems and underscore the importance of tailored approaches to urban governance reform.

Spatial Justice: The Basics offers a concise and accessible introduction to spatial justice as both a theoretical framework and a practical agenda for urban transformation. It examines how urban space is produced, contested, and governed, and how it is implicated in broader dynamics of inequality, recognition, and participation. Drawing on key thinkers such as Henri Lefebvre, Nancy Fraser, Iris Marion Young, Edward Soja, and Susan Fainstein, the book articulates spatial justice through its distributive, procedural, and recognitional dimensions, while also tracing its intellectual genealogy across critical theory, planning thought, and Southern urbanism.

The book centres spatial planning as a normative, political, and ethical practice capable of fostering solidarity, democratising decision-making, and addressing structural injustices. Real-world examples from Indonesia, Colombia, Brazil, the US, and more illustrate how spatial justice is negotiated in practice, while discussions of neoliberal governance, democratic backsliding, and epistemic justice ground the analysis in urgent global challenges.

Designed for upper-level undergraduates, postgraduates, and early-career professionals in planning, geography, architecture, and related fields, the book includes a detailed glossary of key terms, visual diagrams, and analytical tables to support critical engagement and classroom use.

This book equips urban planning professionals, students, and policymakers with the knowledge to not only advocate for public goods but to effectively implement, manage, and maintain them in real-world projects and policies. It offers an in-depth exploration of the economic, legal, and governance intricacies surrounding public goods, highlighting their essential role in fostering social equity and sustainability. Through case studies and practical and theoretical exploration, this guide enables professionals to navigate challenges, make informed decisions, and ensure the equitable provision of public goods in urban contexts. By bridging theory and practice, the book empowers readers to develop and manage public goods with a focus on inclusivity, resilience, and long-term sustainability.

Research on circular development in China’s urban planning remains limited, particularly regarding marginalized groups’ actions. This study addresses the gap by examining circular practices within informal food systems in Chengdu’s urban villages. It highlights residents’ bottom-up initiatives in food production and consumption and their interactions with the broader urban context. Using street interviews and Research through Design, it develops community-based visions to improve these actions and the needed planning tools for implementation. It also explores how circular development could support urban regeneration by recognizing overlooked resources and practices. Semi-structured expert interviews reveal barriers in China’s planning system to accommodate such visions. Findings indicate that local circular actions—driven by local labor and knowledge and efforts to tackle polluted land and idle spaces—offer valuable opportunities for circular development. However, deficiencies in planning tools for spatial planning, waste treatment, land contamination regulation, and vulnerability recognition create barriers to upscaling these initiatives. This study calls for integrating circular development into China’s spatial planning by strengthening top-down tools and fostering grassroots initiatives to promote sustainable resource flows, ecosystem health, and social equity. It also offers broader insights into promoting circular development by recognizing and integrating informal, bottom-up practices in cities undergoing informal settlement regeneration.

In an age marked by converging global crises—climate change, growing inequality, democratic erosion, and increasing socio-spatial inequality and fragmentation—the search for justice has become a definitive imperative for urban planning. One way to explore these issues is through an exercise of collective imagination we call The Manifesto for the Just City. [...]

Climate change is driving cities to transition toward more sustainable urban systems, often implementing these transitions through spatial interventions. However, without a deliberate focus on spatial justice, such climate initiatives risk exacerbating existing socio-spatial inequalities, leading to issues such as green gentrification and maladaptation, which affect vulnerable populations the most. Participatory practices have the potential to foster just transitions, yet they are not well integrated into planning and design processes and are insufficiently linked to spatial justice. This paper introduces a framework that integrates participatory approaches into a typical planning and design cycle through a spatial justice perspective. The framework is applied to eight cases in various geographical contexts, encompassing a range of practices from participatory planning workshops to the development of digital participation tools. Our findings suggest that the framework enables both researchers and practitioners to adopt a more holistic approach to participation in planning and design. Furthermore, we identify key enablers, barriers, and lessons learned from these cases, offering insights that can inform urban practitioners, policymakers, and researchers in advancing spatial justice through participatory planning. Ultimately, this study contributes to enabling just urban transitions by providing a structured approach to embedding spatial justice in participatory planning and design.

This paper examines the impact of recent policies on the transformation of local participatory urban planning in Saudi Arabia since the implementation of Vision 2030 in 2016, highlighting both its potential and challenges. It analyzes the shift from centralized to localized planning at the municipal level and its effects, including increased opportunities for public participation through workshops and digital platforms, as well as the persistence of challenges such as limited public influence on final decisions and inadequate transparency in planning processes. Using a comprehensive literature review, policy document analysis, semi-structured interviews with 20 Saudi urban planners, and a survey of 453 participants, this study reveals significant governance changes. These changes include increased municipal autonomy and the establishment of regional development authorities, which have provided opportunities for local participatory planning. However, the findings also highlight concerns regarding the exclusion of marginalized communities, displacement caused by mega projects, and limited transparency in decision-making processes. While initiatives such as ‘Your Voice Is Heard’, including ‘Balady’ and ‘Istitlaa’, have facilitated a modest degree of public participation, bureaucratic barriers, regulatory complexities, and centralized control continue to hinder the full realization of local participatory planning goals. This study concludes that although policies have improved inclusivity, sustainability, and efficiency, addressing broader ethical concerns and governance challenges is essential for the transformative potential of Vision 2030 to be fully realized in reshaping urban governance in Saudi Arabia.

The mega-regional unevenness, namely the development gap between cores and smaller cities, has increasingly become a key obstacle for inter-city coordination in China. Scholars tend to focus more on the leading role of the cores in responding to this problem. When the smaller cities are mentioned, their endogenous characteristics and weaknesses are often highlighted, rather than being valued as important nodes embedded in the regional network and the inter-city relations. This paper conceptualizes these smaller players in mega-regional system as “secondary cities” to emphasize their interconnectedness to the cores and embeddedness in the inter-city relations. Based on this, we firstly examine the (trans)formation trends of the core-secondary relations in Chinese mega-regionalization. In this way, we focus on the role of secondary cities by exploring the functional and political positioning in the dynamic regional system. Building on such conceptualization of secondary cities, we construct an indicator system to measure changes of core-secondary unevenness from 2006 to 2023. We find that although mega-regionalization aims to rebalance inter-city relations, secondary cities are still facing challenges of polarization and peripheralization. Finally, we conduct a clustering analysis based on the differences between core and secondary cities regarding economic structure, aiming to explore the differentiated vulnerabilities of various types of secondary cities when confronted with polarization and peripheralization. This paper expands the theoretical scope of secondary cities to provide an innovative analytical perspective for understanding the mega-regional unevenness problems in China. Meanwhile, we also emphasize the potential and value of core-secondary relations in addressing the challenges of secondary cities with the expectation of more targeted policy and planning actions.

This chapter discusses resilience in informal settlements amid the COVID-19 pandemic of 2019–2022, focussing on the case of Favela Paraisópolis, a large informal settlement in São Paulo, Brazil. It highlights the importance of community organisation in building resilience while arguing the importance of the State's action in structuring informal spaces as a condition for greater success of community resilience. It seeks to clarify factors leading to community resilience in Paraisópolis and whether these factors can contribute to an expanded understanding of the concept. It does so by revisiting resilience theory and conducting a critical analysis of the history of the pandemic inside the favela, informed by interviews with key stakeholders and health and demographic statistics. It subsequently highlights the limits of these actions organised by an economically and politically oppressed population that lacks the necessary capital to face a health crisis of this magnitude. It draws attention to the risks of a neoliberal appropriation of the concept of resilience as a narrative that delegates the solution of societal problems solely to individuals and communities, taking the State off the hook. Finally, it highlights the power of resilience as a dimension of oppressed communities’ struggles for effective public policies.

The TU Delft Strategic Planning Cycle is a comprehensive strategic planning model designed to enhance urban sustainability and inclusivity by incorporating a range of participatory tools and methodologies that facilitate broad stakeholder engagement through a detailed step-by-step planning cycle.

The TU Delft Strategic Planning Cycle is rooted in the Dutch tradition of democratic visioning and strategic planning, which emphasises the integration of policy and design alongside a strong participatory ethos. This tradition is central to the planning education offered at TU Delft, where students and professionals are trained to approach urban planning with a integrative perspective that combines technical expertise with a deep commitment to democratic processes and sustainable outcomes.

Rechtvaardigheid wordt over de hele wereld gezien als fundament voor menselijke waardigheid en billijkheid. De filosoof John Rawls begint zijn klassieker A theory of justice met de woorden "Rechtvaardigheid is de voornaamste deugd van sociale instituties, zoals de waarheid dat is voor denksystemen. Maar een theorie, hoe elegant en praktisch ook, moet verworpen of herzien worden als deze onwaar blijkt. Net zoals wetten en instituties, hoe efficiënt en doordacht ze ook zijn, hervormd of afgeschaft moeten worden als deze onrechtvaardig blijken". [...]

Mega-regional planning in China is expected to tackle intra-regional unevenness, namely the development gap between regional core cities and the surrounding secondary cities. However, mega-regionalization processes seem to further increase the centrality of cores and push secondary cities towards greater polarization and peripheralization, as they lose socioeconomic vitality, industrial capacity, and political voice. To reflect on why mega-regions are not fulfilling their role of rebalancing regional urban systems, we conceptualize mega-regionalization as a mechanism to coordinate spatial relations within a territory and build a novel framework to analyze the relations between core and secondary cities. First, we show that visions of mega-regional planning regarding core-secondary relations pursue goals of morphological polycentricity, flow multi-directionality, and functional complementarity. Then, we use thematic analysis to evaluate the policy orientations of mega-regional planning to achieve these goals and extract three policy themes governing core-secondary spatial relations - coexistence, connectivity, and cooperation. These can systematically redefine mega-regional planning mechanisms by giving a central role to the spatial relations between core and secondary cities. Emphasizing spatial relations to conceptualize mega-regional governance allows a novel reflection on the challenges of unevenness grounded in the perspective of secondary cities. This deepens our understanding of governance mismatches that keep ideal visions and policy orientations misaligned when seen from secondary cities. Place, priority, and actor mismatches limit the potential of mega-regionalization to respond to their challenges. This research provides a relational understanding of mega-regions, calling for more attention to secondary cities, and the development of more balanced and sustainable mega-regions.

The ongoing debates surrounding sustainability transitions in cities and regions highlight the urgent need to make these transitions fairer, more democratic, and inclusive. Currently, there is increasing recognition that sustainability transitions must be more just to avoid the risk of failure and the deepening of discontent with climate action, particularly in disadvantaged urban areas and among marginalised communities. Similarly, in the field of urban planning, there is a rapidly expanding body of literature on spatial justice, emphasising the need for more equitable planning in terms of the spatial distribution of benefits and burdens, fairness in procedures, and recognition of the diverse needs and interests of different social groups. However, planning practice has yet to keep pace with this trend, and there is a significant knowledge gap regarding how to measure and evaluate spatial justice in the planning process. This paper seeks to address this gap by proposing a spatial justice assessment tool for planning documents. We outline the conceptual model that underpins the tool and demonstrate its application across four European cities.

The assessment is conducted in two phases. The first phase involves using the Values, Strategies, Objectives, and Actions (VSOA) approach to distil essential part of their agenda from the documents prepared by the cities. This approach provides a framework for analysing key components and understanding how values are articulated and translated into actionable measures. It helps to identify the overall vision, the strategies designed to achieve it, the specific objectives set, and the tangible actions proposed. In the second phase, we employ spatial justice as a lens for a qualitative evaluation of how cities address the dimensions of distributive, procedural, and recognition justice within city-wide planning documents. This includes ensuring the fair distribution of burdens and benefits, focusing on processes that do not exacerbate inequalities, and being attentive to needs and aspirations of marginalised and vulnerable groups and identities affected by these transitions.

The paper applies the evaluation tool in four diverse urban contexts: Belfast, Rotterdam, Granollers, and Budapest. These cities vary in size, are located in different parts of Europe, and represent different planning cultures. The plans assessed also cover a range of climate action documents, from overarching sustainability transition plans to more specific energy transition or climate resilience plans. We present and critically evaluate the scores produced by the evaluation of the four planning documents, discussing these findings in relation to the existing literature and considering their implications for planning and policy practice in the context of delivering more just urban sustainability transitions. By deploying the tool in these varied settings, we demonstrate its versatility and broad applicability as a spatial justice assessment framework for urban planning practice. Additionally, we illustrate its potential as a critical discourse analytical tool, revealing the extent to which sustainability transition discourses in urban planning adhere to the principles of spatial justice.

The governmental initiative of high-quality development (HQD) marks a shift in the Chinese development paradigm from prioritizing speed to prioritizing quality towards comprehensive goals of economic growth, social vitality, innovation capacity, industrial upgrading, regional cooperation, and green transformation. This initiative is increasingly discussed within the framework of mega-regions, with prior studies demonstrating that they are critical arenas for promoting HQD visions. However, unevenness within mega-regions has become an important limitation to this vision. Namely, significant disparities exist between mega-regional core cities and the smaller neighboring cities in most HQD indicators. This paper conceptualizes these smaller players as secondary cities. Based on this, this paper aims to understand and differentiate the specific challenges of secondary cities facing intra-regional unevenness in the context of HQD. We build an evaluation framework and employ the TOPSIS method to evaluate 34 core cities and 180 secondary cities. Then, we introduce typological thinking to develop a meaningful classification of secondary cities based on the results of these evaluations. K-means clustering analysis identifies five secondary city types with similar profiles. The analysis supports the discussion of the characteristics and challenges of each type and may contribute to policy recommendations for a balanced HQD in mega-regional secondary cities.

This article identifies the key factors either supporting or blocking the implementation of the Right to the City concept in the urban planning systems of Brazil and Poland. Poland and Brazil, despite some differences, can be compared from the perspective of selected features of spatial planning systems. A characterisation of the spatial planning systems of both countries, including their legal and socio-political conditions, is made. The article identifies these institutional challenges and barriers in both national spatial planning systems, which can be linked to a discussion of the Right to the City concept. It then analyses how elements of the Right to the City concept are implemented in each system and what constitutes the main barrier. Those elements of the Right to the City concept that can be more universally compared were identified. The commonalities and discrepancies found in the two systems are then discussed. In Brazil, the Right to the City concept is much more strongly framed in formal and legal terms, but market and social inequalities are a barrier to its implementation. In Poland, on the other hand, there is a broader institutional inertia in the implementation of the concept. In both countries, there are serious (different) barriers related to the implementation of the Right to the City concept in the urban planning system.

This article explores the use of the pattern language approach in bridging the gap between formal and informal urban planning practices in the African context. This study focuses on a case application within the urbanised region encompassing the Nakivubo wetland located in Kampala, Uganda. As in other cities in Africa with a colonial past, Kampala’s planning system signals a profound gap between a technocratic, European paradigms-based type of planning and the everyday practices of citizens. This results in a “dual city,” with formal and informal communities using resources and spaces differently, leading to spatial segregation and non-implementation of urban plans. To overcome this challenge, the pattern language approach is utilised in this research to link formal and informal practices through facilitating meaningful community participation and integrating tacit knowledge into the planning process. To achieve this, the researchers conducted fieldwork and interacted with the local community in informal settlements to develop informal patterns, while analysing the history and current organisation of formal planning institutions in Kampala to formulate formal patterns. The patterns were used as input for a community workshop, which resulted in a pattern language of wetland management practices and a framework that begins to bridge both formal and informal domains of urban practice. By using the pattern language approach as a tool to understand informal practices and their possible incorporation into a planning process that captures the needs of citizens, this research offers relevant insights into achieving sustainable and inclusive urban environments.

In her book “Doppelgänger: A Trip into the Mirror World,” Naomi Klein (2023) writes about the forces that have destabilised her personal world and which are “part of a much larger web of forces that are destabilising our shared world”. Klein talks about the disagreements she sees in a “mirror world” of distortions. These disagreements are not about a shared reality but about the very nature of reality. What is real? In recent years, our world has been savaged by fake news and “alternative facts,” science denialism, and a profound and seemingly irreversible scepticism towards politics that have destabilised us all. But where does this “war on reality” come from? What has led us to seek our own private unique realities, giving up on broad collective endeavours and visions and, ultimately, giving up on politics? Why has public discourse become so dark? [...]
