Farmers' Markets (FMs) are increasingly recognised for their transformative potential in the food system, as they represent a viable alternative to large-scale food distribution in urban areas. Given their increasing importance at city level, ad hoc urban food policies to regulate FMs have been implemented by several Italian municipalities. However, both policymakers and academia tend to focus on consumers' opinions and needs, while farmers' perspectives on urban food policies regulating FMs have been overlooked, as well as the relationship between various levels of governance involved in FMs. The present research aims to fill this gap by delving into farmers' drivers for selling at FMs, as well as their perceptions on FMs Regulation in Bologna (Italy). The research adopts a Multi-Level Governance (MLG) theoretical approach to show the relationships between the three levels of governance involved in FMs (macro, meso, micro) and provide recommendations on how the governance dynamics can be improved. The study adopts a mixed-methods approach, analysing questionnaire answers with a combination of quantitative and qualitative methods to gather comprehensive insights from FMs farmers. In terms of quantitative methods, the answers of 140 FMs participants are analysed through an Exploratory Factor Analysis (EFA) and a Multinomial Logistic regression model (MNL).

Key findings maintain that farmers' drivers for selling at FMs in Bologna are aligned with the value proposition of Bologna FMs Regulation. Thus, the relationship with consumers, which allows for direct exchange and increased consumers awareness, is the main driver. However, farmers believe the Municipality (the macro level) could further address FMs farmers' needs and drivers (the micro level). The meso level of governance, namely FMs organising associations, should be an intermediary between the macro and the micro levels, that better informs and processes the flow of information and decisions between the two. By analysing farmers' perspectives, this study offers significant insights into the dynamics of local food systems and the role of urban policies in shaping these systems. It highlights the need for harmonising regulatory frameworks with the needs of FMs farmers to improve urban food policies. The findings from Bologna can be helpful for other cities facing similar challenges in urban food system governance.

Capturing spatiotemporal changes in public emotions is an important component of urban human-oriented resilience. Built environment has the potential to conserve the negative effects of hazards. By relying on massive Weibo tweets, this study captures the spatiotemporal patterns of public negative emotions (sadness, fear, and anger) at both the individual and public levels after a landslide. The influence of the built environment on the change rate of public emotion was explored through geographically weighted random forest (GWRF). This study revealed that individuals with a pre-hazard intensity of negative emotions <25 % are more likely to experience heightened negative emotions. The impact of the landslide on the average intensity of public negative emotions is strongest within 3 days after and within a 10 km radius of the landslide. Moreover, townships to the south of the city, farther from the hazard, experienced more pronounced fluctuations in negative emotions, potentially leading to additional social management challenges. Furthermore, in 57.14 % of the townships, the most significant factors were either the built-up area or the industrial land ratio. This study expands the current understanding of public emotions and the influence mechanism of the built environment.

Increasing numbers of families are living in high-rise residences and densified areas of urban centres due to ongoing urbanization. A better understanding of how these environments impact the health of residents is of growing importance for planners and public health practitioners alike. Yet knowledge of the links between high-rise living and specific cohorts like adolescents is lacking. Moreover, youth perspectives are typically ignored in urban planning and building design practices. To address these issues, the present paper employs a community-based participatory research (CBRP) approach that is paired with the Theory of Affordances to investigate how adolescents (n = 22) in two Canadian cities perceive high-rise living and dense environments to impact their mental and physical health. Data was collected between July and December 2023 through geo-tracked, participant-led ‘go-along’ (i.e., walking) interviews (40–120 min) roughly 1 km in length. Inductive thematic analyses supported by an analysis of the captured photos were completed. Noted positive affordances related to high local activity density, rich pedestrian social landscapes, restorative designs, and linkages between built and social environments. Negative affordance themes included poor social control and vitality, risky design legibility, signs of decay, and passive or limited active use designs. Future study is recommended to explore relational, or culturally/socially important public places or designs, and length of residence aspects of the relationship between high-rise living and adolescent health. Implications for design and health practitioners are discussed.

Employment centers serve as crucial drivers of intra-city development, especially in the ubiquitous polycentric transformation. Clarifying the role and impact mechanisms of centers in intra-city growth echoes both theoretical basis and actual needs. However, the empirical understanding is surprisingly limited. Thus, this paper proposes and examines a novel systematical framework with a particular and new focus on the centers' influence. Instead of focusing only on developed regions, both areas outside centers and two types of sub-centers are investigated in this research. The empirical results using Shanghai as a study case show that the effects of agglomeration of centers are mostly insignificant on average but conditioned by three types of proximities to centers. Geographic proximity strengthens the positive role of agglomeration of centers on areas outside centers within the city and developing sub-centers within a certain distance to main-center, but intensifies the siphonic effects for the case of stabilized sub-centers. The industrial proximity only positively moderates the effect of agglomeration of centers on developing sub-centers, while the moderating role of proximity of agglomeration scale to main-center is significantly negative in all areas. These discoveries provide valuable insights for urban spatial and development planning, especially in polycentric cities.

Spatial shortages are jeopardizing the sustainability of cemeteries in urban communities, and to date, few studies have looked at this issue from a comparative lens. Examining cemetery law and policy in Toronto, Ontario, Canada and Sydney, New South Wales, Australia, this paper looks at how these jurisdictions are ignoring or addressing this issue and whether there are opportunities for learning. Using the lens of critical social infrastructure and the novel hybrid methodology of comparative legal geography, the research details the legal frameworks concerning cemeteries in order to understand the roots of the issue and examines whether spatial shortages have prompted government intervention. Although both jurisdictions rely on divergent planning approaches and only one, New South Wales, frames cemeteries within the lens of critical social infrastructure, our findings reveal that the provisioning of cemeteries and the costs of interment have made death an equity issue across urban communities.

While industrialization and commercialization have driven economic growth, the current system calls for integrating alternative economies with capitalism. This study explores the significance of the gift economy and its hybridization with capitalist frameworks to foster societies driven by reciprocity, community development, and social impact. Using qualitative, primary, and secondary data methods, the study analyzes Earthen Routes Community Farm, an urban farm and social project located in Navi Mumbai, India. Findings show that Earthen Routes exemplifies a gift economy with non-monetary transactions, intangible rewards, and community interdependence. It aligns with the United Nations Sustainable Development Goals 11 (Sustainable Cities and Communities) and 13 (Climate Action). It operates on Permaculture principles (Earth-Care, People-Care, Fair-Share) to create social impact rather than profit. The challenges of limited funds and irregular volunteers show that gift economies cannot work in isolation. Rather, their integration with capitalism, a strong vision, and structure can promote reciprocity, empower communities, and foster sustainable societies.

This paper examines city size distributions across 43 African countries from 2013 to 2021, addressing the applicability of Zipf's law, the evolution of urban hierarchies, and spatial interdependencies. Using a novel dataset combining population figures with nighttime light intensity, we test for adherence to Zipf's law, analyze urban dynamics through rank-size distributions and Markov chain models, and employ spatial autoregressive estimation to capture cross-border effects. We find that while population distributions generally follow Zipf's law, economic activity (proxied by nighttime lights) shows deviations, indicating inequality in resource allocation. Regional variations are pronounced, with Southern Africa exhibiting the closest adherence to Zipf's law for population. Urban hierarchy analysis reveals stability at distribution extremes, with medium-sized cities most likely to transition downward. Our spatial analysis uncovers complex interactions between economic, socio-cultural, and political factors in shaping urban structures, highlighting significant indirect effects and regional interdependencies. These findings have important implications for African urban policy, supporting arguments for developing secondary cities to promote balanced economic growth and reduce urban poverty. Our results contribute to understanding complex urbanization patterns in developing economies and inform context-specific, regionally aware urban development strategies.

Street vending, a key component of the informal economy, presents significant challenges for urban governance due to its informal nature, mobility, and conflicts with formal urban activities. While formalization policies aim to regulate street vending by relocating vendors to designated zones, conventional approaches often fail to balance the interests of vendors, residents, and urban authorities, leading to reduced vendor profitability, resistance, and social conflicts. This study addresses this critical gap by proposing a spatial optimization model for dynamic formalization zones, leveraging deep learning and ant colony optimization (ACO) to reconcile spatial governance objectives with vendor preferences. Using Shenzhen as a case study, the research employs street view images and social sensing data to analyze vendor distribution patterns and stakeholder preferences, delineating dynamic formalization zones with permanent “permitted areas” (270,760 m²) and time-specific “restricted areas” (497,610 m²) after 500 iterations. The results demonstrate the model's ability to balance vendor location preferences, resident eviction preferences, and management costs, offering a sustainable solution that preserves vendor mobility and flexibility. This research contributes by introducing a novel method for balancing stakeholder interests, proposing a dynamic governance approach that adapts to the inherent mobility of street vending, and providing actionable policy recommendations for urban managers, emphasizing inclusivity, efficiency, and adaptability in street vending management. By addressing the limitations of conventional formalization strategies, this study offers a practical and scalable solution for promoting inclusive and efficient urban governance.

Recent public crises have introduced significant uncertainty to urban governance on a global scale. Digital innovations leveraging emerging technologies offer effective solutions to manage this uncertainty, leading to widespread adoption in urban governance. This study investigates the factors and mechanisms influencing the adoption and diffusion of the City Brain in the smart city initiatives of 337 cities in China. Utilizing event history analysis, we examine the diffusion characteristics of these innovations among local governments during the COVID-19 pandemic. Our findings indicate that approximately 73 % of the observed cities adopted this digital innovation, displaying an R-shaped diffusion pattern concurrent with the pandemic's spread. Cities with higher levels of digitalization, stronger financial resources and special administrative status were more likely to implement these innovations. Additionally, shifts in political incentives led to a reversed trend in adoption around the fifth year of local leaders' tenure. Early adoption was more prevalent in cities with severe epidemics, though this impact diminished as the epidemic stabilized. This study contributes to understanding the dynamics of digital innovation diffusion in urban governance during public crises.

This article delves into the institutionalization trajectories of grassroots cultural movements in Rome and Marseille, Italy, and France respectively. It explores the development of these practices from the ground up, highlighting how these cultural initiatives aimed at creating inclusive cultural spaces with low barriers to access a number of cultural and creative activities. Through multiple case studies approach to research incorporating semi-structured interviews, field research, and policy analysis, we investigate the process of engagement and collaboration between grassroots movements and local institutions. The study underscores the transformative role of these initiatives as drivers of social and cultural innovation, showcasing examples of how collaboration between these actors and institutional stakeholders can foster the co-creation of urban environments, while addressing concerns related to social cohesion, amidst process of touristification. Additionally, the analysis delves into the role of enabling policies and regulations that have facilitated the processes of these grassroots initiatives, shedding light on the broader socio-political context in which they operate. By examining the interplay between grassroots cultural movements and policy frameworks, we uncover insights into the replicable mechanisms driving the institutionalization of these cultural practices uncovering their potential to inform future urban development strategies.
