Challenges to social, economic, and environmental sustainability are global in scale, yet sustainable development policies must be implemented locally. There has been a tendency for sustainable urbanism projects to engage in the conspicuous sustainability of spatially bounded and highly visible sustainability achievements, rather than spatially expansive, long-term achievements. China's complex system of multilevel governance encourages policy experimentation, but it is also frequently productive of entrepreneurial urbanism and intercity competition. This paper analyses spatial planning documents concerning Hengqin (Zhuhai Municipality, Guangdong Province), an island adjacent to Macao SAR, to show how the ambitions for a new-build district's contributions to sustainable development have become more spatially expansive and ambitious over time. This has occurred alongside changes in project leadership (from city, to provincial, to central government leadership) as well as a deepening awareness of the Greater Bay Area as a region for crossborder policymaking. The paper argues that crossborder perspectives are vital for genuine sustainable development but face certain obstacles in relation to the sites at which policy decisions are made. • Policymakers often prefer conspicuous sustainability to long-term achievements. • Innovative urban entrepreneurialism is common in China's multilevel governance. • Hengqin's spatial planning initially prioritised immediate, localised results. • Centralised leadership and regional awareness can raise sustainability ambitions. • Crossborder perspectives better reflect sustainable development needs.

The renewal of old communities (OCR) is a crucial component of China's urban renewal strategy. However, the huge funding gap, coupled with the unwillingness of enterprises to participate, has impeded the sustainable development of OCR in China. This issue has become a major practical challenge for the government. This study employed the modified theory of planned behavior (M-TPB) to examine enterprise behavior, focusing on how internal capabilities and external conditions influence their participation. Data was collected from 261 questionnaire surveys, and structured equation modeling was used to analyze the data. Further in-depth interviews were conducted to explain and validate the results from the SEM. The findings illustrate that: (1) the M-TPB offers a more detailed and nuanced explanation of the mechanisms influencing participation behavior; (2) the attitude towards participation is an important factor in shaping the intention to participate; (3) there is a significant negative correlation between perceived behavioral control, which is based on external conditions, and the participation intention; and (4) different types of enterprises show differences in attitude and perceived behavioral control. These findings provide new insights and perspectives on the OCR dilemma in China, highlighting some important practical implications for fostering various forms of enterprise participation in OCR projects. • This paper analyzes enterprises' participation in OCR from a new perspective - the behavioral intention of managers. • The modified theory of planned behavior can better explain the influence mechanism. • Government should focus on improving the enterprises' attitude and the effectiveness of external conditions. • Propose strategies to promote participation for different types of enterprises.

Addressing the global urgency for improved sustainable cities and communities, as per the United Nations Sustainable Development Goal (SDG) 11, requires innovative and disruptive approaches, which also include applying artificial intelligence (AI). While AI holds significant potential to address complex socio-economic and environmental challenges in cities, a comprehensive analysis of its applications and implications, particularly in urban contexts, is required to address the research gap in understanding how AI can be effectively deployed to meet the challenges. This paper reports on a study that evaluates how AI may facilitate achieving SDG 11. This assessment includes an expert-driven literature review, drawing insights from authoritative sources. In addition, a set of case studies illustrate practical applications of AI to improve urban sustainability. The combination of these approaches led to findings that underscore the pivotal role of AI in optimizing energy use, streamlining waste management, enhancing traffic flow, and contributing to environmental sustainability. However, according to the findings, AI implementation needs oversight to ensure it is ethical, inclusive, and privacy-respecting as an effective tool to aid decision-making. By fostering collaboration among planners, policymakers, and AI experts, the full potential of AI may be unlocked to shape sustainable urban environments and realize SDG 11. • Artificial Intelligence may assist in implementing sustainable development. • Cities and communities can become more sustainable with the use of AI. • There is a research gap on using AI to promote sustainable cities. • Some AI technologies may be used in urban contexts. • Various social, and environmental issues and obstacles need to be overcome.

The urgent decline of global progress towards achieving the Sustainable Development Goals (SDGs) in the post-COVID-19 era necessitates immediate action in the field of smart cities. This paper proposes a new framework to assess the performance of global smart cities, emphasizing the vitality and potential of sustainability-oriented smartness for global smart cities, as well as the role of benchmarking cities on a global scale. The framework centered around the principles of "humanity-technology-sustainability" tackles critical challenges related to feasibility, interoperability, and flexibility in smart city assessments. By integrating academic perceptions with quantitative performance results, the proposed framework aims to facilitate the advancement of sustainable smart city through urban comparisons and the expansion of global visions within the smart city ecosystem in a post-pandemic future. In each of the past three years, twenty globally renowned cities for smart city development are assessed under this framework and published on UNPAN (United Nations Public Administration Network) website. These assessments aim to draw the attention of more cities to the factors that contribute to advancing smart cities under the new world development goals, to identify benchmark cities across different dimensions, and to assist decision-makers in prioritizing future smart city development initiatives. • SDGs call for urgent responses in the field of smart cities in the Post-pandemic era • The multivocal in sustainability makes the goal of sustainable smart city ambiguous • Bridge the gap between sustainability vision and sustainability goal in smart city • The new smart city assessment framework based on "humanity-technology-sustainability" • 20 global metropolia as smart city benchmarks are assessed under the framework [ABSTRACT FROM AUTHOR]

This paper presents an in-depth city profile analyzing Martil—an emerging coastal satellite urban center in northern Morocco. Situated within a rapidly urbanizing context, Martil exemplifies organic satellite city dynamics in the Global South. The analysis tracks Martil's demographic, spatial, economic, social, environmental, and planning transformations since the 1970s. Accelerated rural-urban migration fueled unstructured peripheral expansion, straining infrastructure and producing socioeconomic disparities. Unregulated construction encroached on floodplains and coastal habitats, increasing climate risks and environmental degradation. Recent urban development plans aim to balance growth priorities with sustainability concerns through zoning, partnerships, and critical projects. However, persisting governance gaps between ambitions and on-ground outcomes continue to hinder equitable development and ecological resilience. The study situates Martil locally and comparatively, underscoring mismatches between prevailing models and satellites' distinct realities. Satellite urbanism's complexities validate calls for fundamental paradigm shifts prioritizing social welfare, climate adaptation, economic diversity, and participatory planning essential for sustainable urban development. This multi-dimensional analysis of a rapidly evolving coastal satellite city on the Mediterranean contributes an original perspective to urban studies scholarship while offering integrated recommendations for practitioners and policymakers. • Rapid coastal satellite urbanization trends unpacked through Martil city case profile • Population influx and unstructured peripheral expansion fuel socioeconomic and ecological pressures • Environmental hazards and groundwater risks analyzed vis-à-vis uncontrolled construction • Intent and implementation gaps in balancing urban growth with sustainability surface • Comparative insights on coastal satellites inform adaptive planning and policy pathways [ABSTRACT FROM AUTHOR]

An understanding of how modern Open Data Ecosystems (ODEs) work is critical in the context of current trends towards sustainability and smartness, while is seen to be an asset to support urban governance and development, in coordinating actions, and fostering civic engagement. This paper aims to establish such understanding by analyzing the contextual patterns, platforms, and components shaping sustainable ODEs by employing platform theory. This study explores and compares characteristics, similarities, differences, and best approaches in 19 cities across 8 countries. In this study we (1) identify 50 patterns that influence and shape sustainable ODEs and their platforms, i.e., Open Data Platform Ecosystems (ODPEs); (2) explore the relationships between platforms and other ODPEs components by developing a respective model, and identifying internal platforms and other components; (3) empirically validate the conceptual findings of five types of ODPEs presented in the literature, redefining them from the conceptual to real-life implementation of the respective components in sample cities; (4) considering the experience gained during the study with respect to the ODPEs and external pressures and environments that shape or influence them, we define 12 recommendations for policy planning and urban governance of more sustainable ODEs. • Identifies 50 patterns that influence and shape sustainable ODEs in smart cities • Defines the Open Data Platform Ecosystem (ODPE) and its components and relationships • Empirically validates the conceptual findings of five types of smart city ODPEs • Defines 12 recommendations for urban development of more sustainable ODEs [ABSTRACT FROM AUTHOR]

History matters. Yet, explanations about the contemporary dynamics around informal settlements in global South cities are often divorced from their historical antecedents. We argue that a retrospective approach is important in analyzing and understanding the current dynamics around informal settlements. Applying the historical institutionalism approach and the concepts of critical junctures and path dependency, this paper develops an institutionalist approach to exploring the messy and complex dynamics of urban informal settlements in Abuja, Nigeria. Using interviews, focus group discussions, document analysis, and participant observations, we identify four key critical junctures: the Federal Capital Territory (FCT) ACT of 1976; the Land Use ACT of 1978, the 1979 master plan of Abuja, and the attempted demolition of Mpape in 2012 and the resulting 5-year court case that ended in 2017. These critical junctures have created path dependencies that explain the contemporary state of the urban informal settlements in Abuja, particularly in relation to land rights and tenure (in)security. This study shows how inconsistencies in the formulation of policies and their implementation in the planning of cities are a result of historically embedded problems. Insights into such historical legacies are the first step to a comprehensive understanding and future planning of urban informal settlements. • History matters. Contemporary cities are shaped by legacies of the past as well as current governance circumstances. • The use of critical junctures and path dependency frameworks provides meaningful insights into the informalisation processes of informal settlements. • Informal settlements in Abuja are the result of the path-dependent actions of the state and non-state actors. • Insights into historical legacies are important for sustainable future planning and regularisation of urban informal settlements. • Future studies on urban informal settlements need to account for the historical antecedents and path-dependencies in their governance.

This study explores the impact of political uncertainty on sustainable urban development by examining carbon emission trading systems (ETS) in four major markets in China (Beijing, Shanghai, Guangdong, and Hubei) from 2014 to 2022. As an alternative to carbon taxes, carbon ETS markets have become increasingly popular due to their success in reducing greenhouse gas emissions. However, their effectiveness is often hindered by political instability and uncertainty. Utilising logistic regression and AR(1)-GARCH estimations, we identify a negative relationship between political uncertainty and carbon trading volume. Our study also reveals significant variations in the responses of these markets to political uncertainty. The paper contributes to the understanding of how ETS markets operate in a complex and constantly changing political environment. We suggest that policymakers need to consider the impact of political uncertainty on carbon trading when designing and implementing urban policies that promote sustainable development. Additionally, our research contributes to the development of urban policies that can be effectively implemented in both developed and developing regions. • Local government official turnovers are used as the measurement of political uncertainty. • Daily transaction data from four carbon ETS markets (Beijing, Shanghai, Hubei and Guangdong) in China • Considered the probability and proportion of zero transaction day • Logistic regression and AR(1)-GARCH estimations • A negative relationship between political uncertainty and carbon transaction volume [ABSTRACT FROM AUTHOR]

The aim of this paper is to analyze at what extent the connectivity of small localities is a determinant of their demography. Specifically, we pay attention to three factors: the evolution of the population; the distance, measured both in kilometres and travel time, to the province capital, the usual city where the largest set of services is available; and finally, the coverage of different kinds of broadband services (from ADSL or 3.5 G to the fastest ones FTTH) in rural areas. An econometric model was estimated where the dependent variable captures the increase of inhabitants along 2017–2020 of the 5955 Spanish municipalities with a population between 101 and 10,000 inhabitants (73.3 % of all municipalities). The results point out to the following facts: digital connectivity of small localities is a determinant of their demography, whatever the technology used, but physical distance remains being a significant factor on the population growth (both if it is measured of physical distance or travelling time) to explain the population growth of each locality. • Digital connectivity of small localities is a determinant of their demography. • Internet connections are a new communication channel to promote/deter depopulation in rural areas. • Internet access is positively correlated with population growth in small/medium populations. • The distance to the provincial capital continues to be a factor that slows down population growth.
