This disparity in evidence persists even as African cities face intensifying challenges related to rapid urbanization, socio-political complexity, and environmental degradation. This study, responds to this existential gap by critically investigating the evolving green spaces dynamics in Abuja, Nigeria—a rapidly expanding capital city. Drawing on qualitative data from interviews with key urban development stakeholders, the research identifies six interconnected mechanisms shaping green space transformation: governance and political influence, urbanization and land use pressures, economic incentives and developer influence, institutional and operational challenges, societal and behavioral drivers, and legal and illegal conversions. These forces interact to weaken green space protection, intensify land commodification, and exacerbate spatial and environmental injustices. Quantitative analyses reveal a steep decline in green space availability—from 42.43 % in 1990–17.9 % in 2023—alongside a fall in per capita availability from 73 m² to 22.68 m², with significant intra-urban disparities. The loss of accessible green areas has constrained recreational opportunities, particularly for high density communities, undermining health and social equity. Comparisons with global urban regions show Abuja's challenges resonate with patterns across Africa and Asia, contrasting with the more regulated approaches seen in Europe. The study advocates for integrated governance reforms, zoning reform, participatory green planning, enforcement mechanisms, and community led-stewardship to reposition green spaces as vital assets for urban sustainability and spatial justice.</div></div>","PeriodicalId":47399,"journal":{"name":"Progress in Planning","volume":"203 1","pages":"Article 101033"},"PeriodicalIF":5.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147604921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tools such as design controls and review panels have been found to discriminate against minority groups, to raise development costs, catalyse gentrification, and cause displacements and evictions. A key challenge for public authorities is thus to reconcile the pursuit of high-quality urban design with justice considerations. Addressing this challenge, this paper makes three contributions. First, it problematises the way that ‘good’ design is currently pursued through planning systems, exposing its exclusionary potential. Second, it introduces a tool for assessing public authority design interventions from a justice perspective. Third, it uses this tool as part of a critical analysis of design guides and codes in England in 2024. Through this analysis, the authors highlight numerous ways in which existing design guides and codes are failing to support <em>urban design justice</em>. These include promoting characteristics that can have exclusionary effects, failing to acknowledge the drawbacks of ‘good’ design, ignoring existing forms of injustice, enabling tokenistic public participation, and failing to recognise user needs and preferences. Our analysis shows, overall, that support for urban design justice in England is largely rhetorical, and that unjust outcomes are likely where new developments meet policy requirements. The paper finishes by calling for public authorities to recognise the justice implications of their design interventions, including through what we term ‘just good enough’ approaches.</div></div>","PeriodicalId":47399,"journal":{"name":"Progress in Planning","volume":"203 1","pages":"Article 101034"},"PeriodicalIF":5.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147605000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developed over a period of some twenty-five years, Scotland’s placemaking agenda is often upheld for its ambitious commitment to ‘design value’ and pursuit of social and environmental policy goals. Despite this, there has yet to be a comprehensive study of the agenda and its implementation. This paper’s originality lies in its comprehensive response to this gap, which it addresses in two ways using a rigorous methodology combining primary interview and survey data, archival research, and direct observations of the built environment. First, we trace the evolution of Scotland’s post-devolution planning and urban design policies and highlight their relative divergence from those in the other nations of the UK. Second, we examine the implementation of the placemaking agenda on-the-ground in a series of housing development case studies. From this analysis, we demonstrate that a distinct and progressive commitment to placemaking has emerged in Scotland post-devolution but reveal that implementation has struggled to keep up. We argue that a series of stubborn barriers to implementation have prevented the full realisation of Scotland’s placemaking agenda. Through a fine-grained focus on the cultures of design governance practice that facilitate delivery, we contend that these deeply engrained barriers cannot be addressed by policy change alone, and require a more substantial rethink of Scotland’s placemaking practice. The conclusions are of theoretical and practical significance for understanding the context-dependent cultures of implementation within which design governance and placemaking occur.</div></div>","PeriodicalId":47399,"journal":{"name":"Progress in Planning","volume":"203 1","pages":"Article 101031"},"PeriodicalIF":5.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147605004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It begins with a critical genealogy of debates since the 1940s and identifies a persistent fault line: Planning construed either as an independent methodological discipline centered on decision-making processes, or as a substantive practice embedded within political–economic contexts— a distinction that can be translated into a tension between procedural universality and contextual particularity. This division has led to confusions in the literature. The findings show that many past disputes conflate the subject, principles, and questions or problematic areas at stake. To address this, the study adopts an Avicennian schema, introducing a new order to the field and—without siding with any pole or rejecting them—situating each aspect of planning theory in its proper place. It then advances a four-level typology of planning theories organized by nature, function, central questions, and fundamental problems. In a further step, it proposes a framework that makes explicit the foundational philosophical presuppositions underlying planning theories. The typology positions deontic, evaluative, descriptive, explanatory, critical, and justificatory theories within a single map, while the philosophical framework exposes the value-laden assumptions that shape theorizing. The paper’s contribution is threefold: (i) it identifies the place of each aspect of planning theory and the various types of planning theories; (ii) it offers criteria for comparing them; and (iii) it provides a usable scaffold for research, pedagogy, and practice.</div></div>","PeriodicalId":47399,"journal":{"name":"Progress in Planning","volume":"203 1","pages":"Article 101030"},"PeriodicalIF":5.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147605002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In parallel, for several decades, the Healthy Cities paradigm has evolved as a holistic and context-sensitive approach to enhancing urban health and quality of life (QOL) through integrated planning, participatory governance, and cross-sectoral action. This study conducts a PRISMA-guided systematic review of the co-benefits and trade-offs associated with the dimensions and solutions of healthy cities in relation to the SDGs. In this process, 91 peer-reviewed articles published between 2016 and 2025 were retrieved from major international databases and analysed using a structured qualitative content analysis to identify dominant patterns, co-benefits, and trade-offs. The findings indicate that existing research primarily focuses on SDGs 3 and 11, while also revealing meaningful linkages with SDGs 2, 6, 9, 13, 16, and 17. Healthy city interventions, including green and blue infrastructure, active mobility systems, inclusive governance mechanisms, and evidence-informed policymaking, demonstrate substantial potential to generate co-benefits across environmental, socio-spatial, and institutional dimensions. Nevertheless, the literature highlights persistent challenges and trade-offs, such as digital exclusion, institutional fragmentation, and spatial and social inequalities in access to health-enabling environments, which continue to hinder progress toward these goals. The results show that the identified co-benefits and trade-offs are strongly place-dependent. Local culture and social norms, urban morphology and density patterns, urban microclimate conditions, mobility and accessibility structures, and institutional and financial capacities play a decisive role in shaping how healthy city strategies interact with the SDGs across different regions and cities worldwide. Accordingly, the effective integration of the Healthy Cities paradigm within the SDG framework requires translating global objectives into locally implementable planning actions and designing neighbourhood-scale, context-sensitive monitoring indicators. To achieve sustainable and equitable outcomes, urban policies should prioritise reducing socio-spatial inequalities, strengthening inclusive civic participation, and mainstreaming health considerations across all dimensions of urban development. The study underscores the need to advance place-based empirical research, context-responsive innovations, and interdisciplinary collaboration to fully realise the potential of healthy cities in shaping sustainable, resilient, and health-oriented urban futures.</div></div>","PeriodicalId":47399,"journal":{"name":"Progress in Planning","volume":"203 1","pages":"Article 101032"},"PeriodicalIF":5.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147604999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Finding answers on this, and also on the question of how to strike an effective balance between desired fundamental transformation and realistic expectations, was at the heart of the Interreg Europe project 2050 CliMobCity (2050 Climate-friendly Mobility in Cities). The project partners were four medium-sized but otherwise quite different cities (Bydgoszcz, Plymouth, Thessaloniki and Leipzig), along with the Potsdam Institute for Climate Impact Research (PIK) and TU Delft. Each partner city conducted a so-called demonstration study, which required defining ambitious packages of measures (mobility, land use, electrification) and forecasting changes in mobility by macroscopic transport modelling. PIK then analysed GHG emissions using its carbon model. This paper extends the demonstration studies into a case-study approach. This is preceded by an exercise in consistently structuring types of GHG and mobility performances and corresponding measures. The case-study approach is supplemented by a review of the literature on shared and micromobility. A conclusion drawn from the case study is that none of the partner cities is in fact sufficiently reducing GHG emissions. Even if electricity production was completely green, the remaining gap between GHG reduction aims and analysed GHG delivery lies between 30–81 %, dependent on the scenario and city. Shared and micromobility seem not to lead to strongly deviating conclusions. We discuss policies to close the gap. One major option discussed is tackling GHG emissions from urban freight, in forms such as organising public-private cooperation designed to accelerate the electrification of freight vehicles.</div></div>","PeriodicalId":47399,"journal":{"name":"Progress in Planning","volume":"202 ","pages":"Article 101021"},"PeriodicalIF":5.7,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145705730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The second synthesizes urban quality criteria suggested by experts over time to define the Urban Requisites for an exemplary city. The research then shows how each Urban Requisite contributes to the fulfilment of each Core Value and, therefore, of the Wishful City itself. Rather than proposing an urban utopia, this study considers the city as a continuous, collective creation, where individual contributions should support common needs and aspirations.

Environmental deterioration is another challenge threatening cities. To avoid hazardous environmental exposure, citizens increase the reliance on indoor space while this causes an emerging challenge to human health and wellbeing. Addressing more than one challenge in an urban context is essential. Preparing for an increasingly hot era is urgent for both developing and developed nations to mitigate negative consequences, and there is a need of biophilic design to integrate humans and nature. However, few studies have explored the integration of heat–resilient design and biophilic design. This study aims to address this gap by developing a framework for heat–resilient biophilic street (HERBST) design, where the street is highlighted for its key role in public activity. This study delineates biophilic theory and outlines biophilic street design elements, activities, attitudes and knowledge, and institutions and governance based on literature review. Afterwards, this study analyses heat–resilient street design in terms of design goals, implementation pathways, and issues addressed to clarify the potential of integrating biophilic street design and heat–resilient street design. Furthermore, this study reveals the relevance and complementarity between the two and defines the HERBST framework. In particular, the HERBST framework aims to reduce heat stress for pedestrians, increase the time people spend outdoors, increase social interaction, and alleviate heat-related physical and mental health problems while strengthening the connection between people and nature. The technical pathway of the HERBST framework is categorized into heat mitigation, adaptation, and management. Heat mitigation includes measures for transport planning, road facilities, building facades, and pocket parks; heat adaptation is linked to lifestyles, multi-sensory experiences, mental health, and social connectivity; and heat management is linked to governance systems, economic structures, and advocacy and education. The HERBST framework implementation is elucidated through site analysis, goal setting, planning and design, implementation, maintenance and management, and post-occupancy evaluation. Finally, this study discusses the research, design, cognitive, social, cultural, institutional, regulatory, and economic barriers associated with HERBST and provides recommendations.
