A Methodological Framework for High-Resolution Surface Urban Heat Island Mapping: Integration of UAS Remote Sensing, GIS, and the Local Climate Zoning Concept

The urban heat island effect (UHI) is among the major challenges of urban climate, which is continuously intensifying its impact on urban life and functioning. Against the backdrop of increasingly prolonged heatwaves observed in recent years, practical questions about adaptation measures in cities are growing—questions that traditional meteorological monitoring can hardly answer adequately. On the other hand, UHI has long been the focus of research interest, but due to the technological complexity of providing accurate spatially referenced data at high spatial resolution and the requirement to survey at strictly defined parts of the day, information provision is becoming a major challenge. This is one of the main reasons why UHI research results are less often used directly in urban spatial planning. However, advances in geospatial technologies, including unmanned aerial systems (UASs), are providing more and more reliable tools that can be applied to achieve better and higher-quality information resources that adequately characterize the UHI phenomenon. This paper presents a developed and tested methodology for the rapid and efficient assessment and mapping of the effects of surface urban heat island (SUHI). It is entirely based on the integrated use of data from unmanned aerial systems (UAS)-based remote sensing methods, including thermal photogrammetry and GIS-based analysis methods. The study follows the understanding that correct SUHI research depends on a proper understanding of the urban geosystem, its spatial and structural heterogeneity, and its functional systems, which in turn can only be achieved by supporting the research process with accurate and reliable information resources. In this regard, the possibilities offered by the proposed methodological scheme for efficient geospatial registration of SUHI variations at the microscale, including the calculation of intra-urban SUHI intensity, are discussed in detail. The methodology builds on classical approaches for using local climate zoning (LCZ), adding capabilities for precise delineation of individual zone types and for geostatistical characterization of the urban surface heat island (SUHI). Finally, the proposed scheme is based on state-of-the-art technological tools that provide flexible and automated capabilities to investigate the phenomenon at microscales, including by enabling flexible observation of its dynamics in terms of heat wave manifestation and evolution. Results are presented from a series of sequential tests conducted on the largest residential area in Bulgaria’s capital city, Sofia, in terms of area and population, over a relatively long period from 2021 to 2024.

A Historical Perspective Through the Lens of the Islamic City Theory: Konya Example

The concept of the Islamic city elucidates the spatial structures specific to Islam religion and civilization, deeply influencing the lives of Muslims. Despite geographical, ethnic, and cultural diversities, it has been observed that the fundamental influence of the religion shaped similar urban formations in the Islamic geography. A key determining factor in the transition from traditional bedouin tribal life to urban civilization is the need for more suitable settlements to meet the multifaceted requirements and rituals of Islam. Societies embracing Islam have restructured their ways of life, with mosques becoming centers of worship, simultaneously reshaping legal, administrative, educational, and commercial structures, thereby becoming central to urban life. Islamic cities, reaching their zenith during the Golden Age of Islam, gradually weakened over time during the processes of modernization/secularization, with the rise of rational/bureaucratic powers diminishing their role as the primary shaping force of space. Konya, representing the characteristics of the Islamic city during the Seljuk and Ottoman Empires, underwent significant transformations approaching the modern era, affecting its physical, social, economic, and administrative fabric. Particularly in the Republican era, the Islamic city features were sidelined due to modernist spatial shaping, but have recently regained importance with the emergence of Islamic political movements and approaches by National Vision (Milli Görüş) municipalities. This study examines the Islamic city from a historical perspective, highlighting common characteristics of Islamic cities worldwide, scrutinizing the erosive effects of secularization/modernization trends on the Islamic city, specifically focusing on Konya, and finally evaluating recent revitalization policies directed towards the Islamic city in Konya.

Spatial participatory planning for urban logistics: A GIS-enhanced Real-Time Spatial Delphi approach

Effective urban logistics planning plays a crucial role in effectively managing infrastructure and transportation networks, contributing to the mitigation of negative externalities associated with last-mile deliveries and fostering city sustainability. Among the various facets of supply chain management, selecting appropriate locations in urban areas for logistics facilities, such as automated parcel lockers and smart loading bays, stands out. However, the complexity of decision-making in this context, involving diverse stakeholders with potential conflicting objectives, poses a significant challenge in reaching a common consensus. This paper proposes an innovative approach to address this issue by adopting a spatial participatory process that combines GIS models and Real-Time Spatial Delphi to identify suitable locations for two logistic facilities. The case study is the city of Dublin (Ireland), where an Urban Living Lab of the H2020 project SENATOR is based. A modified Delphi is used, first gathering expert opinions on preferences and objectives. These insights are then used to develop a spatial analysis using GIS, ranking areas according to the expert preferences. These outcomes form the basis for the Real-Time Spatial Delphi, where stakeholders and experts working on the project collaboratively engage to achieve a spatial consensus on the territory. The findings of this study provide valuable information for stakeholders, policymakers, local authorities, and governmental bodies to implement specific actions. Through the active involvement of key actors in the decision-making process, this approach ensures that the selected locations for logistics facilities align with the needs of all parties involved.

The proposal of a 15-minute city composite index through integrating GPS trajectory data-inferred urban function attraction based on the Bayesian framework

The chrono-urbanism framework suggests that urban life quality decreases with increased time spent in transportation, particularly motorized modes. The 15-min city concept, aligned with chrono-urbanism, emphasizes the importance of reaching essential urban functions within a short active travel time and has gained global attention. This study aims to develop a 15-min city composite index score (CIS) using the chrono-urbanism framework. The CIS integrates spatial accessibility to six key urban functions, providing a holistic assessment of the 15-min city status in Wuhan, China. Urban function accessibility is computed based on visitor volume inferred from GPS trajectory data using the Bayesian framework. Results reveal CIS hotspots in Hongshan, Wuchang, Jiangan, and Qingshan districts, with Hongshan having the highest concentration. However, Wuhan faces challenges in achieving comprehensive 15-min city status, as hotspots are mainly concentrated in specific areas like university towns and traditional city centers. The proposed assessment approach is applicable to accurately evaluate the 15-min status in other urban contexts using GPS trajectory data. The study's findings can assist policymakers in understanding CIS hotspot distribution and developing future planning policies to enhance the overall 15-min city status.

Quantitative Analysis of the Future of the Sharing Economy, Housing, White-Collar Labor Markets, and Problems in Big Cities

This research project explores the future of the sharing economy and its profound effects on housing markets, white-collar labor dynamics, and socio-economic challenges in large metropolitan areas. Using quantitative economics and econometric techniques, the study evaluates how platforms such as Airbnb, Uber, and coworking spaces are reshaping urban life, exacerbating housing affordability issues, and altering labor market structures. By analyzing housing market data, labor statistics, and platform economy data from major cities like New York, London, and Istanbul, this research provides empirical insights into how the sharing economy influences urban economic landscapes. The study employs difference-in-differences (DiD) and multivariate regression models to assess causal relationships, particularly in terms of housing market disruptions caused by short-term rental platforms and labor market fragmentation driven by the rise of gig and remote work. Spatial econometric techniques are also used to explore geographic disparities in housing and employment impacts across urban districts. Preliminary findings indicate that the proliferation of sharing economy platforms has contributed to housing shortages and increased prices in central urban areas, while labor markets experience growing polarization, with high-skilled workers benefiting from remote work opportunities and low-skilled gig workers facing economic precarity. This research offers valuable policy insights into the regulation of short-term rentals and the protection of gig economy workers, highlighting the need for regulatory frameworks that address urban inequality and labor market shifts. By integrating data from multiple sources, this study contributes to the academic discourse on urban economics and provides a framework for understanding the long-term socio-economic implications of the sharing economy in big cities.

Contesting the Anticipated Infrastructural City: A Grounded Analysis of Silk Road Urbanization in the Multipurpose Port Terminal in Chancay, Peru

A new private port and logistics complex is under construction in the city of Chancay, located north of Lima, Peru, as part of China’s Belt and Road Initiative (BRI) promising to change life in the city while expanding a Sino-centric globalized economy and Peru’s reach within it. Through a series of interviews conducted between 2020 and 2022 and document analysis, we seek to offer a grounded theorization of how the BRI, as an exemplar of infrastructure-led urbanization, interweaves with broader sociospatial and socionatural transformations, affecting the present and future of the places where it materializes. By using the concept of the infrastructural city we show how the combination of port and logistics infrastructures with spatial interventions in periurban space is guiding contemporary urbanization, resulting in the formation of a new, amorphous city that has as its defining characteristic the domination of infrastructure over urban life, eradicating prior functions and marginalizing local grievances to facilitate the creation of a privatized enclave for international trade. Our analysis provides insights into the intricate and multifaceted geographies of emerging Chinese-sponsored infrastructural strategies, the hopes and struggles that contextually shape them, and the potentially distinctive and contested urban features of the anticipated infrastructural cities yet to come.

Centro e centralidades em foco: um olhar acerca do Gávea Centro e suas centralidades no Setor Sul de Uberlândia-MG

The general objective of this article is to explore the urban dynamics and the different conceptions of center and centrality; The specific objectives are to address the emergence of new centralities and their dialectic in the continuous movement of space production in the city and to highlight centrality as a possibility for improving the quality of urban life. Given its character as a reflexive effort, it is methodologically supported by a bibliography review and a brief approach to the empirical reality of Uberlândia-MG. It does not have the purpose of exhausting the theoretical framework on the subject, but is more of a brief interpellation, an invitation to debate. The text is divided into three parts, in addition to the introduction. Initially, it addresses the conceptualization of city and urban, in order to highlight the constant change in the structure of cities, well understood in the following topic, which addresses the concepts of center and centrality. In the following part, possibilities inherent to centralities are suggested. The last topic, in turn, is discussed based on the theories presented the conjuncture of the Southern Sector of the city of Uberlândia-MG, where will be constituted the Gávea Center with its centralities: Villa Gávea, Park Gávea and Gávea Garden.

The new private urban governance: Vestiges, ventures and visibility

Despite the growth, prevalence and influence of private urban governance, scholarship that explores the intimate workings of these manifold and mutating forms remains limited. While these private ventures carry forward elements from the past, the landscape of urban governance has nonetheless undergone profound transformation. Over the past few decades, the global expansion and influence of private governing ventures have reshaped how cities are managed, organised and experienced. This special issue on the New Private Urban Governance examines the constantly evolving modalities of private governance (i.e. business improvement districts/areas, condominium/strata corporations, gated communities, POPS and others) in a global context. Organised around new, interrelated themes of vestiges, ventures and visibility, this issue comprises case studies, syntheses of longstanding empirical projects and novel theoretical/conceptual interventions into political and spatial practices, knowledges and technologies of these privately governed realms. Focused on the spatialisation of politics, vestiges reflects the idea that while neoliberal forms of private urban governance continue to proliferate, they rely and build upon, rather than fully replace, earlier, more public governance practices, logics and spaces. Ventures emphasises that the private and market-oriented thrust of urban governance is heavily predicated on the protection and extraction of value and the intensifying financialisation of urban landscapes and life. Visibility highlights how governing technologies render private urban governance visible and in doing so highlight the politics of space. These three themes together expose the workings of the new private urban governance while invigorating further explorations of this complex phenomenon.

Social Networks within the City: Remaking the City through Movement and Collecting Materials in Johannesburg, South Africa

This study examines the dynamics of networks among informal recyclers in Fietas, Johannesburg, South Africa, focussing on how these networks embody their struggle for the "Right to the City." By observing informal recycling activities across various Johannesburg suburbs, the study highlights how recycling not only provides livelihoods for the unemployed but also allows marginalised groups to assert their presence and rights within the cityscape. Building upon Adama's (2012) analysis of urban livelihoods and social networks, this research explores the interactions and spatial practices of informal recyclers in Johannesburg. Informal recyclers develop connections with city stakeholders that demonstrate interdependencies crucial for their survival and claiming space within the city. These networks are vital for accessing resources such as recyclable waste, which provides essential needs like food and shelter. These everyday practices underscore the importance of social connections in building networks that sustain livelihoods and assert a right to belong in the city. The nature of these networks varies by location, policies, and social relations. Some are shaped by power dynamics and monopolies, while others reflect interdependence and mutual support. This paper argues that recognising these diverse networks is key to understanding how informal recyclers navigate the urban landscape. In line with Harvey's (2003) "Right to the City," these networks reflect efforts to reshape urban spaces to meet recyclers' needs, despite structural challenges. As Sung (2021) shows, hierarchies and power dynamics influence access to resources, highlighting the contested nature of urban life for informal recyclers.

Green horizons: Exploring the potential of vertical green walls

The term “Green walls” also known as vertical gardens or living walls has emerged as a promising solution to combat the environmental challenges posed by rapid urbanization. This review explores the concept ornamental, plant choice suitable and benefits associated with green walls in urban settings. Utilising vegetation to cover vertical surfaces, green walls offer several benefits to the environment, society and economy. They contribute to improved air quality, noise reduction, energy conservation and biodiversity enhancement. Vertical greenery allows for the utilization of unused wall surfaces, creating green areas without occupying valuable ground space, which is often scarce in urban environments. Additionally, green walls offer aesthetic appeal, promote urban agriculture and create opportunities for community engagement. However, their implementation requires careful consideration of factors such as structural integrity, irrigation and maintenance. Despite these challenges, green walls offer a sustainable and innovative approach to enhancing the quality of urban life while mitigating the negative impacts of urban development on the environment. The current emphasis highlights the significance of green walls as an effective tool in sustainable urban planning, underscoring the need for further research and their integration into urban planning practices.

The Neglected Modern Architectural Heritage: Analysis of Housing Estates in the Second Half of the 20th Century from Izmir, Turkey, Case Study Area

Twentieth-century housing estates are an important part of the architectural heritage of the modern age, reflecting not only the evolution of housing forms, but also the technological advances and sociocultural dynamics of the twentieth century. However, awareness of the value of this heritage is still insufficient, resulting in a lack of legal protection and numerous threats in the form of transformation and negligence. In this research, we present the problem using the example of modernist Turkish architecture. The settlements of Izmir, a cosmopolitan port city with a diverse socio-cultural fabric and rapidly developing housing architecture, are chosen as the subject of the study. The main objective of the study is to evaluate the state of conservation and the degree of transformation of the selected estates. The overall assessment of the maintenance of the legibility of urban layouts and the form of individual buildings shows that, despite the lack of systematic protection, it is possible to preserve the existing architectural heritage in the examples analyzed and to provide recommendations for future policies to sustain the heritage values of modernism. The research aims to fill the existing gaps in the discourse on modern housing and contribute to a broader international dialogue on the conservation of modern architecture. By including these estates in the ongoing discussion, we recognize their historical significance and promote their preservation as important participants in contemporary urban life.

Urban Livability Assessment in South Korea: Incorporating Climate Change Vulnerability

This study aims to develop an urban livability assessment index that incorporates climate change vulnerability and to apply this index to urban areas in South Korea, thereby analyzing the impact of climate change on living environments and quality of life. Existing frameworks for livability indices often fail to adequately reflect the long-term risks associated with climate change. Consequently, this research proposes a new livability index that includes climate change vulnerability, establishing a policy foundation aimed at protecting and enhancing the quality of life for urban residents. The methodology integrates existing livability indicators with climate change vulnerability indicators across 219 cities and districts in South Korea. Utilizing panel regression analysis and Local Indicators of Spatial Association (LISA) analysis, the study evaluates the spatial clustering characteristics and potential risks in each area. The results indicate that urban infrastructure significantly influences livability, with climate change vulnerability indicators forming high clusters primarily in southern regions. Furthermore, the study confirms economic disparities within the metropolitan area, as well as the exacerbation of social inequalities in regions vulnerable to disaster safety and social services. This research underscores the necessity of integrating climate change vulnerability into livability indices, suggesting that such indices can serve as critical criteria for urban policy formulation and the evaluation of regeneration projects.

Revisiting modern campuses through spaces for leisure in Izmir, Turkey

ABSTRACT Division of working and leisure spaces as an early product of modern life has still its traces on urban context. Campus spaces, not only universities, reflect such a programmed structure related to modern everyday life. This paper aims to discuss the changing relationship between working and leisure on varying campus spaces, which embrace these two essential components of modern societies. Many campuses in early Turkey follow similar modernist organisational principles in their design and performs an original path in spatial transformation. Industry, education, and public service campuses, which were established in İzmir during the 1950s, constitute the spatial framework of this paper. The paper aims to trace the leisure areas of three campuses and examine this meticulously programmed life idea under the influence of the changing leisure spatial culture in Turkey from the 1950s to today. These spaces are articulated and examined by their dwellings and social interaction spaces. Besides, the social experience and individual perspectives of campus users are documented and merged with the physical analysis of the working and leisure spaces. Discussing those examples in socio-spatial details underlines the transformation and dissolution of campus idea in urban life and exposes the unique experience of campus spaces of İzmir.

Using Local Entropy Mapping as an Approach to Quantify Surface Temperature Changes Induced by Urban Parks in Mexico City

Understanding the mechanisms whereby parks contribute to cooling urban settings is critical to effectively addressing the challenges posed by rising temperatures in densely populated cities and ultimately improving the quality of urban life. This study employs a spatial approach with advanced analytical techniques, including local entropy mapping, to quantify surface temperature changes induced by urban parks across different geographical areas. Using satellite imagery to estimate land surface temperature (LST) during a heat wave in Mexico City, the study provides a practical approach to understanding the complex relationship between urban park size and urban heat island intensity within 300 m. The study’s findings indicate that while parks exert a cooling influence on their immediate vicinity, the extent of this effect varies spatially and depends on factors such as the size and location of the park and the nature of the surrounding terrain. Specifically, the results indicate that this relationship is not randomly distributed across the urban landscape. Instead, there is a clear pattern of spatial clustering within the city. Consequently, this research underlines the complexity of the problem, emphasizing the indispensable role of urban design and planning strategies to harness the full potential of parks as cooling agents within cities.

Academic Traces of Urban Furniture: A Bibliometric Perspective

Urban furniture, which increases the quality and aesthetics of urban life, has recently been the subject of academic studies. However, a bibliometric and visual analysis in this field has not been conducted in sufficient number. This paper presents a quantitative and descriptive study of 1,063 documents from the Web of Science database (1975-2022) using RStudio's 'Bibliometrix' package. Key bibliometric indicators include 887 documents, 619 references, 582 articles, 12.25 citations per document, 2,558 authors, 1,386 keywords, keywords of 2,968 authors, and a collaboration index of 16.8%. The study found higher scientific productivity in China and the USA. Research status, influential sources, countries, institutions, authors, keywords and data relationships were analysed. In particular, it was observed that academic interest increased after 2000 and focused on technology, environment and urban disciplines rather than architecture. The keywords (Author's Keywords and Keywords plus) vary, with a focus on the urban field of study and the health and environment field of study, but both keywords are increasing. The paper recommends increased interdisciplinary co-operation to broaden the scope of urban furniture research. This is one of the first comprehensive bibliometric and content analyses on urban furniture.

Sustainability Optimization Method of Built Environment with Integrated Physical Environment and Virtual Perception Simulation: A Case Study of Campus Open Space

High-quality built environments significantly enhance residents’ health, urban livability, and sustainability. However, the lack of precise pre-evaluation of designs and user perceptions during the design phase often results in suboptimal improvements. This study proposes a method for evaluating and optimizing design schemes based on multidimensional physical environment simulations and virtual perception, using a university campus as a case study. Initially, we establish simulation models for sound, wind, thermal, and light environments and analyze the current state of virtual perception in the campus environment. Subsequently, we integrate the evaluation results of the physical environment and virtual perception to identify three priority intervention areas and develop corresponding design strategies. Finally, we reapply the method for pre-evaluation of the design schemes and further optimize the designs. The results show that the optimized schemes receive positive feedback in virtual perception evaluations. This study leverages the combined use of multidimensional physical environment simulations and VR technology to create an immersive virtual environment with measurable physical perception experiences, providing a new approach for guiding the sustainability of built environments.

Study on the Optimization of Urban Traffic and Spatial Structure in the Environment of Low-Carbon Eco-Cities

Under the concept of “dual-carbon development”, optimising the spatial structure of urban life, perfecting the management system of public transport services, realising the spatial optimisation of urban transport, minimising carbon emissions and reducing environmental pollution are the problems that need to be solved urgently. This paper firstly analyses the development status quo of low-carbon cities, clarifies the influencing factors of low-carbon eco-cities, and discusses the correlation between the scale, population density, traffic structure and energy development of low-carbon eco-cities and low-carbon eco-cities. On this basis, the low-carbon ecological development strategy of City C in China is proposed as an example. Therefore, this study argues that low-carbon cities, as a strategic goal of new urbanisation development, should focus on constructing a theoretical system of urban upgrading and optimisation under the environment of green and sustainable ecological development, and introduce corresponding construction guarantee optimisation policies.

Working hours influence preferences of residents for micro features of small urban green spaces

This study investigates whether duration of working hours affect residents’ preferences for the micro-features of Small Urban Green Spaces (SUGS), and explores differences across genders and visitation purposes. Little is known about this subject, yet it is crucial for creating more equitable green spaces. In phase 1, participants (n = 209; 30.9 ± 6.73 years, 59.3%male) were categorized by average daily working hours (0–8 h, 8–10 h, 10 h+), and rated 41 micro-feature images on their importance for visiting SUGS. Phase 2 included the top ten features ranked from phase 1, with participants (n = 256; 30.8 ± 5.12 years, 35.2% female) completing the Kano model survey to identify and explain the importance of features and different types of needs. Findings reveal a clear trend: extended work hours pivot resident preferences towards green space attributes promoting physical activity. For residents of 0–8 h valued aesthetic elements like sculptures and vegetation, while lighting became paramount for those with 8–10 h, and for those working over 10 h prioritized facilities for active engagement, such as playground equipment and slow runway. These distinctions provide valuable guidance for designing SUGS with diverse feature combinations that cater to the needs of residential areas with varying socio-economic backgrounds and occupational lifestyles, thereby enhancing urban livability.

Morphological Analysis of Public Spaces and Their Contribution to Urban Resilience in Guelma, Algeria

Modern Algerian cities are facing various uncertainties, both natural and human-made. To address these risks, urban areas need to be more adaptable and responsive. The increasing impact of climate change and the recent pandemic have emphasized the importance of outdoor spaces. As people spend a significant amount of time in these areas, public spaces have become essential for urban life. This study conducts a comparative analysis of public spaces, using a grid-based methodology to identify similarities and differences between two resilient public spaces and the square of Guelma. The analysis is preceded by a literature review that establishes key conceptual frameworks. The main objective is to develop recommendations for resilient public spaces and their contribution to a city's environmental resilience, particularly its capacity to withstand climate change. By understanding how these spaces can mitigate the effects of climate change, this research aims to guide the design and management of urban environments.
