As smart cities expand rapidly due to urbanization, economic growth, and political support, concerns around sustainability have emerged. There is a lack of supporting frameworks that describe the interactions and behaviors of key variables facilitating the sustainability of smart cities. This study aims to formulate a conceptual framework linking smart cities and sustainability through a systematic literature review. A review was conducted which yielded extensive insights into sustainability in smart cities. Out of the 2596 articles examined, 82 focus on smart cities and sustainability. A bibliometric analysis was performed to identify the authorship and affiliation of selected publications, followed by a content analysis offering a detailed assessment of the studies. First, the literature review revealed a robust connection between smart cities and sustainability, as illustrated through a network visualization diagram. Second, the Triple Bottom Line (TBL) theory was employed to elucidate crucial elements of smart cities and their relationships with sustainability. Finally, a conceptual framework was formulated to explain the principal factors promoting the sustainability of smart cities. The findings have significant managerial and strategic implications for the advancement of smart cities and suggest potential areas for further research in exploring sustainability within smart cities.

As infrastructures mushroom across Africa, this article investigates narratives accompanying infrastructural investments in East African cities, Djibouti-city (Djibouti) and Berbera (Somaliland). While cities in the Global North move towards a post-industrial future, the Horn of Africa depicts other endpoints, breaking with experiences of colonisation while hoping to diminish asymmetries in a Western-dominated global system. Inspired by models that condense idealized experiences of urban success elsewhere, Djibouti and Somaliland rework historical narratives while envisioning their future as urban nodes interlinking different places and cultures. We build on Koselleck's theory of historical time and link it to notions of ‘elsewhere’ to show how different actors rework past experiences and future expectations through port modernizations. On the one hand, port operators and logistics companies use city labels and propagate developmental trajectories that assimilate East African cities to Dubai or Shekou models. On the other hand, political elites and city residents search in these projects for their own path, creatively combining elements of similarity and distinctiveness while developing the city's specific brand. Through qualitative interviews substantiated with secondary sources, this article shows how infrastructure becomes a driver of identity promoting spatial imaginaries, re-invigorating (shared) memories, and formulating aspirations drawing on different times and places.

Low-carbon policies can shape individual environmental behaviors, yet how policy intensity influences willingness to pay (WTP) for environmental protection, across diverse socioeconomic and geographic contexts, remains poorly understood. Drawing on a nationwide survey in China (N = 22,012), we find a U-shaped relationship between the intensity of low-carbon policies and residents' WTP. This nonlinearity differs markedly between urban and rural populations: rural residents display a steeper U-shaped response, while for urban residents, higher socioeconomic status (SES) transforms the U-shaped curve into a positive linear gradient. Spatial analyses (Global and Local Moran's I) reveal pronounced clustering, with high WTP concentrated in ecologically dependent, less-urbanized regions and low WTP in more urbanized regions, including Beijing and its surroundings. These findings underscore the complexity of policy impacts across social and spatial dimensions, offering insights into how tailored, context-sensitive strategies may enhance public engagement and foster more equitable pathways to sustainable development.

Under the mounting pressure from global warming, green roofs emerge as a valuable source for climate adaptation, particularly in compact metropolises where green space is limited. Consequently, there is a need to quantitatively evaluate the potential for roof greening where it is most needed and suitable. Despite the increasing importance of this issue, there have been limited studies on the effectiveness of remote sensing and deep learning in identifying the potential for roof greening in many cities. To address this, we have created a GreenRoof dataset, comprising approximately 6400 pairs of remote sensing images and corresponding masks of roofs with high greening potential in four European cities. Afterward, we exploit the capabilities of deep learning methods to identify roofs that are suitable for greening from remote sensing images. Using 15 German cities as a case study for future urban rooftop planning, we estimate the spatial potential for retrofitting green roofs. Structural parameters for prioritizing green roof implementation include vegetation coverage, thermal environment, and building density. Results indicate that the total area suitable for green roof retrofitting exceeds 20 % of the roof area in the 15 German cities examined. The spatial analysis effectively reflects variation in demand and suitability for green roof retrofitting across different cities. In conclusion, this study provides a versatile screening approach utilizing remote sensing, deep learning, and spatial analysis, which can be readily adapted to inform municipal policies in other cities aiming to promote green roofs and enhance sustainable urban development.

With the rapid expansion of urban rail transit networks, an accessibility-usage mismatch has been revealed, where taxi trips have pick-up and drop-off points within metro catchment areas, yet commuters choose taxis (i.e., metro-replaceable trips). Existing literature fails to reveal the underlying reasons, fully account for influencing factors, or identify weather-sensitive metro stations. To address these, this study develops a comprehensive framework, including metro-replaceable trip identification, feature extraction, SHapley Additive exPlanations (SHAP) approach for identifying driving factors, and clustering algorithms for recognizing commuting patterns and weather-sensitive metro stations. The main findings are: (1) Weather conditions are the driving factors. (2) Rain prompts a shift from the metro to taxis, while in cold or windy weather, commuters prefer the metro. (3) Thresholds to alleviate the mismatch include travel distances over 7500 (morning) and 6000 m (evening); Metro-Taxi time ratio below 2.6 (morning); Taxi-Metro price ratio over 6.5 (evening); and departure times outside 7:40–8:40 and 17:45–18:55. (4) For commercial metro stations, density is more crucial, while diversity matters more for residential ones. (5) Weather-sensitive stations are located in densely populated residential or commercial areas, with entrances along Wuhan's primary roads. These findings offer valuable insights to promote green commuting and improve metro competitiveness.

The rapid and impactful growth of urban areas necessitates a thorough understanding of settlement development pathways to inform effective urban planning. This study investigates settlement developments on the Swiss Plateau from 1899 to 2021, focusing on identifying, describing, and predicting archetypes of settlement development. Using historical maps, we classified neighborhood types by urban form as a proxy for use and density, then analyzed their composition in each of 1999 settlements across 11 time-steps. By clustering the resulting time series, we identified five distinct archetypes of settlement development. We found that settlement size and proximity to other settlements are related to the development archetype. Distance to train stations and highway ramps influence the likelihood of settlements evolving into specific archetypes. By employing predictive modeling, it was demonstrated that the settlement characteristics of the earliest time step allow for the prediction of the development archetype. Consequently, the predictive model was utilized to predict future archetypes of contemporary settlements. Some settlements' predicted future archetypes differed from their historical ones, indicating potential transitions and opportunities for urban planners to guide these changes. The research highlights how understanding settlement dynamics and the role of key drivers can help urban planners guide development towards desirable pathways.

The paper investigates the role of museums as public spaces in the city. By bridging literature in urban planning and museum studies, we examine the physical spaces museums create and how the public interacts within these spaces. Our analysis centers on ARoS, an art museum, and Den Gamle By, an open-air history museum, in Aarhus, Denmark. Using Kurt Iveson's (2007) twofold description of public space—topographic and procedural—we use a combination of site visits, archival documents, and websites to analyze the impact of these museums on urban design and their engagement with the public. This research illustrates how museums function not only as landmarks but also as sites imbued with civic and cultural values, as well as fluid spaces that extend their impact beyond their walls. Moreover, this paper highlights how museums' influence in the city transcends their physical presence. It emphasizes their role in facilitating debates and informal learning, while fostering social interactions, and inclusion within their spaces. These findings are relevant for city officials and museum managers who could embrace museums' role as public spaces in their dual function—enhancing the cityscape and fostering community building—and make them integral partners in urban development.

Rapid technological advances have improved the convenience and efficiency of modern urban life. However, how we might promote the abilities of humans and communities to adapt to digital transformations has not been adequately considered. Therefore, this study focuses on how we might shape a healthy smart environment promoting human experiences toward a seamless adaption facing the city's smartisation. The research framework comprises three dimensions: urban cognitive context, human interactive experience, and subjective wellbeing. We conducted structured interviews in two smart cities—Seoul and Sydney—to compare the interactive experiences and subjective wellbeing of inhabitants. We found that an integrated physical–digital environment focusing on place-based have led to a high level of cognitive, affective, and achievement wellbeing. Based on this result, we propose a smart social sustainability model based on two proposed dimensions—smart context and smart context experience dimension— that may be used by future urban planners and policymakers to develop human-friendly smart cities.

Hydrogen is a pivotal driver of the green economy and clean energy transition, and global efforts are underway to scale up hydrogen technology and its adoption. This study explores China's hydrogen fuel cell vehicle (HFCV) city clusters policy, launched in 2021, involving five clusters consisting of 44 cities, to boost the country's hydrogen economy. Drawing on cluster theory, collaborative network literature, and evolutionary economic geography, we investigate the connections between hydrogen city clusters and historical geographically based and industrial-based clusters, as well as the formation of collaborative networks among cities. By comparing these heterogeneous city networks, our findings highlight the competitive edge of HFCV city clusters that capitalize on resource and innovation complementarity instead of relying solely on geographical positioning or pre-existing collaborations. The results of the Exponential Random Graph Analysis reveal that existing clusters, economic strength of cities, and their strategic positions within the hydrogen industrial chain significantly shape collaborative networks. This study contributes to cluster policy research by examining how China's HFCV city clusters integrate historical advantages while fostering synergies with less connected cities, offering valuable insights into inter-city collaboration and strategies for sustainable industrial development.

In South Korea, an unprecedented conflict between natives and migrant Muslims has erupted over the construction of a mosque in Daegu's Buk-gu district. This study examines the role of the local government in this conflict by applying Foucault's concepts of biopolitics and security dispositifs. Specifically, it analyzes how the local government's administrative actions, such as issuing a stop-work order, reflect power dynamics between the native South Korean population and migrant Muslims. The study finds that the administration's use of biopower, facilitated by administrative inaction and a policy vacuum, favors the native population and disadvantages the Muslim community. Based on these findings, the study recommends that, in an era of decentralization, the central-local government relationship should be strengthened, and horizontal governance frameworks should be established to address conflicts and ensure more inclusive treatment of migrant populations.
