Building upon paradigms of language and languaging practices as "local" phenomena (Canagarajah, 2013; Pennycook, 2010, Pietikäinen & Kelly-Holmes, 2013), this paper narrates a teacher's experience in an undergraduate seminar in applied language studies as an exploration in transdisciplinarity-as-localization. Taught by the author in 2012-2013, the seminar was intended as an introduction to the politics of societal multilingualism as visible in the linguistic landscape of public texts. As such, it relied upon its own geographic and institutional locality, as well as the diverse conceptual moorings and methodologies of linguistic landscape research (e.g., Blommaert, 2013; Shohamy & Gorter, 2009; Trumper-Hecht, 2010) in order to lead students in interpreting the significance of East Asian languages in the San Francisco Bay Area. However, as the paper endeavors to show, the course's own curriculum--and with it, the locus of teacherly authority--was forced to de-localize as the implementation of curricular ideals in practice revealed heterogeneous and expansive orders of meaning.

The coronavirus disease 2019 (COVID-19) pandemic and respective shutdowns dramatically altered human activities, potentially changing human pressures on urban-dwelling animals. Here, we use such COVID-19-induced variation in human presence to evaluate, across multiple temporal scales, how urban birds from five countries changed their tolerance towards humans, measured as escape distance. We collected 6369 escape responses for 147 species and found that human numbers in parks at a given hour, day, week or year (before and during shutdowns) had a little effect on birds escape distances. All effects centered around zero, except for the actual human numbers during escape trial (hourly scale) that correlated negatively, albeit weakly, with escape distance. The results were similar across countries and most species. Our results highlight the resilience of birds to changes in human numbers on multiple temporal scales, the complexities of linking animal fear responses to human behavior, and the challenge of quantifying both simultaneously in situ.

First-ever measurements of particulate matter (PM2.5, PM10, and TSP) along with gaseous pollutants (CO, NO2, and SO2) were performed from June 2019 to April 2020 in Faisalabad, Metropolitan, Pakistan, to assess their seasonal variations; Summer 2019, Autumn 2019, Winter 2019-2020, and Spring 2020. Pollutant measurements were carried out at 30 locations with a 3-km grid distance from the Sitara Chemical Industry in District Faisalabad to Bhianwala, Sargodha Road, Tehsil Lalian, District Chiniot. ArcGIS 10.8 was used to interpolate pollutant concentrations using the inverse distance weightage method. PM2.5, PM10, and TSP concentrations were highest in summer, and lowest in autumn or winter. CO, NO2, and SO2 concentrations were highest in summer or spring and lowest in winter. Seasonal average NO2 and SO2 concentrations exceeded WHO annual air quality guide values. For all 4 seasons, some sites had better air quality than others. Even in these cleaner sites air quality index (AQI) was unhealthy for sensitive groups and the less good sites showed Very critical AQI (> 500). Dust-bound carbon and sulfur contents were higher in spring (64 mg g-1) and summer (1.17 mg g-1) and lower in autumn (55 mg g-1) and winter (1.08 mg g-1). Venous blood analysis of 20 individuals showed cadmium and lead concentrations higher than WHO permissible limits. Those individuals exposed to direct roadside pollution for longer periods because of their occupation tended to show higher Pb and Cd blood concentrations. It is concluded that air quality along the roadside is extremely poor and potentially damaging to the health of exposed workers.

Legacy effects describe the persistent, long-term impacts on an ecosystem following the removal of an abiotic or biotic feature. Redlining, a policy that codified racial segregation and disinvestment in minoritized neighborhoods, has produced legacy effects with profound impacts on urban ecosystem structure and health. These legacies have detrimentally impacted public health outcomes, socioeconomic stability, and environmental health. However, the collateral impacts of redlining on wildlife communities are uncertain. Here, we investigated whether faunal biodiversity was associated with redlining. We used home-owner loan corporation (HOLC) maps [grades A (i.e., "best" and "greenlined"), B, C, and D (i.e., "hazardous" and "redlined")] across four cities in California and contributory science data (iNaturalist) to estimate alpha and beta diversity across six clades (mammals, birds, insects, arachnids, reptiles, and amphibians) as a function of HOLC grade. We found that in greenlined neighborhoods, unique species were detected with less sampling effort, with redlined neighborhoods needing over 8,000 observations to detect the same number of unique species. Historically redlined neighborhoods had lower native and nonnative species richness compared to greenlined neighborhoods across each city, with disparities remaining at the clade level. Further, community composition (i.e., beta diversity) consistently differed among HOLC grades for all cities, including large differences in species assemblage observed between green and redlined neighborhoods. Our work spotlights the lasting effects of social injustices on the community ecology of cities, emphasizing that urban conservation and management efforts must incorporate an antiracist, justice-informed lens to improve biodiversity in urban environments.

Cities represent a significant and growing portion of global carbon dioxide (CO2) emissions. Quantifying urban emissions and trends over time is needed to evaluate the efficacy of policy targeting emission reductions as well as to understand more fundamental questions about the urban biosphere. A number of approaches have been proposed to measure, report, and verify (MRV) changes in urban CO2 emissions. Here we show that a modest capital cost, spatially dense network of sensors, the Berkeley Environmental Air Quality and CO2 Network (BEACO2N), in combination with Bayesian inversions, result in a synthesis of measured CO2 concentrations and meteorology to yield an improved estimate of CO2 emissions and provide a cost-effective and accurate assessment of CO2 emissions trends over time. We describe nearly 5 years of continuous CO2 observations (2018-2022) in a midsized urban region (the San Francisco Bay Area). These observed concentrations constrain a Bayesian inversion that indicates the interannual trend in urban CO2 emissions in the region has been a modest decrease at a rate of 1.8 ± 0.3%/year. We interpret this decrease as primarily due to passenger vehicle electrification, reducing on-road emissions at a rate of 2.6 ± 0.7%/year.

There are more incidents of violence in summer and on hot days, a trend likely to be exacerbated by climate change. Urban areas experience additional temperature modulation due to the urban form, however, to date, no studies have considered the effect of the urban heat island (UHI) or green space with respect to the temperature-violence relationship. This study modelled the relationship between the number of daily violent crime incidents that occurred inside or outside between July 2013 and June 2018, and the average surface UHI or percentage greencover (including grasses, shrubs and trees) within each local government area in Greater Sydney, Australia. Panelised negative binomial time series regression models indicated that the violent crime rate was associated with higher surface UHI for crimes committed outside (p = 0.006) but not inside (p = 0.072). Greater percentage of all vegetation was associated with significantly lower rates of violent crime committed outside (p = 0.011) but was not associated with violent crimes committed inside (p = 0.430). More socio-economic disadvantage was associated with higher rates of violent crime committed inside (p = 0.002) but not outside (p = 0.145). Greater temperature was non-linearly associated with higher rates of violent crime committed both inside and outside (p

Urbanization has altered land surface properties driving changes in micro-climates. Urban form influences peoples activities, environmental exposures, and health. Developing detailed and unified longitudinal measures of urban form is essential to quantify these relationships. Local Climate Zones [LCZ] are a culturally-neutral urban form classification scheme. To date, longitudinal LCZ maps at large scales (i.e., national, continental, or global) are not available. We developed an approach to map LCZs for the continental US from 1986 to 2020 at 100 m spatial resolution. We developed lightweight contextual random forest models using a hybrid model development pipeline that leveraged crowdsourced and expert labeling and cloud-enabled modeling - an approach that could be generalized to other countries and continents. Our model achieved good performance: 0.76 overall accuracy (0.55-0.96 class-wise F1 scores). To our knowledge, this is the first high-resolution, longitudinal LCZ map for the continental US. Our work may be useful for a variety of fields including earth system science, urban planning, and public health.

In response to biodiversity loss and biotic community homogenization in urbanized landscapes, there are increasing efforts to conserve and increase biodiversity within urban areas. Accordingly, around the world, previously extirpated species are (re)colonizing and otherwise infiltrating urban landscapes, while other species are disappearing from these landscapes. Tracking the occurrence of traditionally urban intolerant species and loss of traditionally urban tolerant species should be a management goal of urban areas, but we generally lack tools to study this phenomenon. To address this gap, we first used species occurrences from iNaturalist, a large collaborative dataset of species observations, to calculate an urban association index (UAI) for 967 native animal species that occur in the city of Los Angeles. On average, the occurrence of native species was negatively associated with our composite measure of urban intensity, with the exception of snails and slugs, which instead occur more frequently in areas of increased urban intensity. Next, we assessed 8,348 0.25 x 0.25 mile grids across the City of Los Angeles to determine the average grid-level UAI scores (i.e., a summary of the UAIs present in a grid cell, which we term Community Urban Tolerance Index or CUTI). We found that areas of higher urban intensity host more urban tolerant species, but also that taxonomic groups differ in their aggregate tolerance of urban areas, and that spatial patterns of tolerance vary between groups. The framework established here has been designed to be iteratively reevaluated by city managers of Los Angeles in order to track the progress of initiatives to preserve and encourage urban biodiversity, but can be rescaled to sample different regions within the city or different cities altogether to provide a valuable tool for city managers globally.

Street networks allow people and goods to move through cities, but they are vulnerable to disasters like floods, earthquakes, and terrorist attacks. Well-planned network design can make a city more resilient and robust to such disruptions, but we still know little about worldwide patterns of vulnerability, or worldwide empirical relationships between specific design characteristics and resilience. This study quantifies and measures the vulnerability of the street networks of every urban area in the world then models the relationships between vulnerability and street network design characteristics. To do so, we simulate over 2.4 billion trips across more than 8,000 urban areas in 178 countries, while also simulating network disruption events representing floods, earthquakes, and targeted attacks. We find that disrupting high-centrality nodes severely impacts network function. All else equal, networks with higher connectivity, fewer chokepoints, or less circuity are less vulnerable to disruption's impacts. This study thus contributes a new global understanding of network design and vulnerability to the literature. We argue that these design characteristics offer high leverage points for street network resilience and robustness that planners should emphasize when designing or retrofitting urban networks.

We investigate the dynamic characteristics of Covid-19 daily infection rates in Taiwan during its initial surge period, focusing on 79 districts within the seven largest cities. By employing computational techniques, we extract 18 features from each district-specific curve, transforming unstructured data into structured data. Our analysis reveals distinct patterns of asymmetric growth and decline among the curves. Utilizing theoretical information measurements such as conditional entropy and mutual information, we identify major factors of order-1 and order-2 that influence the peak value and curvature at the peak of the curves, crucial features characterizing the infection rates. Additionally, we examine the impact of geographic and socioeconomic factors on the curves by encoding each of the 79 districts with two binary characteristics: North-vs-South and Urban-vs-Suburban. Furthermore, leveraging this data-driven understanding at the district level, we explore the fine-scale behavioral effects on disease spread by examining the similarity among 96 age-group-specific curves within urban districts of Taipei and suburban districts of New Taipei City, which collectively represent a substantial portion of the nations population. Our findings highlight the implicit influence of human behaviors related to living, traveling, and working on the dynamics of Covid-19 transmission in Taiwan.

This paper describes a dataset collected by infrared thermography, a non-contact, non-intrusive technique to acquire data and analyze the built environment in various aspects. While most studies focus on the city and building scales, an observatory installed on a rooftop provides high temporal and spatial resolution observations with dynamic interactions on the district scale. The rooftop infrared thermography observatory with a multi-modal platform capable of assessing a wide range of dynamic processes in urban systems was deployed in Singapore. It was placed on the top of two buildings that overlook the outdoor context of the National University of Singapore campus. The platform collects remote sensing data from tropical areas on a temporal scale, allowing users to determine the temperature trend of individual features such as buildings, roads, and vegetation. The dataset includes 1,365,921 thermal images collected on average at approximately 10-second intervals from two locations during ten months.

This article examines the enduring iconicity, multifaceted functions, and changing meanings of the Astor Hotel in Tianjin—one of the first international hotels in modern China—from the mid-19th century to the 21st century. Originally built more than 150 years ago, the Astor Hotel still stands exactly where it did in the former British Concession in Tianjin. This hotel was not only a venue boasting Tianjin's most expensive accommodations but also a crucial site where politics, technology, economics, social, and cultural changes intersected and developed in its treaty port incarnation. Moreover, the expansion of the Astor Hotel evolved along with the development of Tianjin from a hypercolonial city to a Chinese-run metropolis. Shortly after the Communist Revolution in China, its ownership was overtaken by the Tianjin Municipal Government. Following a sequence of major renovations and commercial relaunches in the 1990s, the Astor Hotel was restored and reconstructed as an emblem of Tianjin's historical status as an international and cosmopolitan city in China. Both continuity and changes will be emphasised in the discussion of the Astor Hotel's history, as well as its multiple functions and shifting symbolic significance. [ABSTRACT FROM AUTHOR]

Urbanization is occurring at an unprecedented rate in developing countries like Ethiopia, especially with the rapid growth of industrialization. However, this urbanization and industrial development surge puts immense pressure on preparing and implementing city spatial plans. Urban spatial planning plays a crucial role in shaping the development of cities, aiming to create livable and sustainable urban development. The plan-making process and its subsequent implementation often encounter challenges that hinder the realization of planned objectives. Galan and Dukem, cities near Addis Ababa's capital, have seen substantial industrial investment in recent decades. This article explores the challenges associated with urban spatial planning and industrial development while proposing alternative approaches. The paper relies on information gathered from primary and secondary sources, including expert surveys and key informants' interviews. The research highlights that industrial developments have led to significant and uncontrolled changes in urban land use and urbanization in the study areas. Due to the lack of clear planning guidelines and institutional capacity, the study cities are experiencing haphazard development without effective urban spatial plans. Proximity to Addis Ababa has driven the urbanization process through increased investments. The article contends that effective management of urbanization and industrialization can create enjoyable living conditions and foster job growth. Macroeconomic policies, including industrial policies, should pay attention to spatial elements and prevent policy-making processes that are "space-blind". This, however, requires clairvoyance and a high level of expertise, integrating inputs from advocacy planning and community participation to bridge gaps and ensure effective urban spatial plans and industrialization processes.

Governments around the world have instrumentalised the idea of cities as innovation hubs in the drive for economic competitiveness and governance of anticipated futures. Producers of global indicators have identified cities as key actors in the global competition for talent – a race for human capital taking place against rapid technological changes, and political and social disruptions. In this article, we examine the rise of global cities as innovation hubs and its role in tackling global challenges. Using qualitative content analysis and conceptual analysis of strategies from rival cities in Europe (Amsterdam vs Copenhagen) and Asia (Singapore vs Hong Kong), we unpack how future cities are articulated and constructed in the nexus of migration and knowledge policy. We find that global indicators are actively used to produce more 'robust futures' that shape policymaking and strategies of cities while delimiting alternatives and potential 'creative future visions' in addressing global challenges.

Context: Landscape change affects biological diversity and the distribution of species traits related to spiritual, educational, and recreational benefits people derive from nature. These traits are associated with color, song and behavioral characteristics that influence people's perceptions of how attractive an assemblage is. However, the environmental variables that affect the spatial distribution of traits related to the attractiveness of biological diversity remain unexplored. Objectives: We tested how landscape structure influences patterns of perceived bird attractiveness (trait diversity associated with colorfulness, behavioral and song categories) across an urbanization gradient. Methods: We used data from standardized surveys of birds and landscapes within 42 landscape units of 1km2 across the city of Brisbane in eastern Australia. We used structural equation modeling to test effects of landscape composition (built infrastructure, percentage of tree cover) and landscape configuration (fragmentation of tree cover) on mean bird community attractiveness. Relationships between individual traits and landscape structure were analyzed using multinomial logistic regression models. Results: Our analysis across 82 bird species shows that the relative amount of built infrastructure in a landscape interacts with fragmentation to reduce the overall attractiveness of the landscape’s bird assemblage. However, built areas can exhibit high overall bird attractiveness where there is (1) reduced fragmentation and (2) increased diversity of vegetation structure that provides key habitats for many colorful species with a high diversity of calls. Relationships between bird attractiveness and landscape structure change when they are analyzed at the guild level (insectivores vs frugivores/nectarivores). In addition, body size moderates the effects of landscape structure on song complexity, personality, and color. Conclusions: Small bodied, colorful and melodious species are negatively affected by built infrastructure and fragmentation. By learning how habitat loss and fragmentation affect the distribution of species-rich, attractive bird assemblages, our findings can inform how urban landscapes might be structured to increase people’s connection with nature.

Urban greening has become an increasingly popular strategy to improve urban life and human health. However, there are indications that the presence and extent of urban greenness may increase the abundance of wild rats. Therefore, we investigated which environmental and socio-economic factors are associated with rat abundance, with a focus on factors related to urban greenness. We systematically trapped rats (222 Rattus norvegicus and 5 Rattus rattus) in parks and residential areas in three cities in the Netherlands. We modelled the relative abundance of rats against various environmental and socio-economic variables. In addition, we compared municipality rat complaint data with our trapping data and analysed trap success over time. We observed positive relationships between the relative abundance of rats and both greenness (NDVI) and different proxies for food resources (restaurants and petting zoos). In addition, there were more municipality rat complaints in residential areas compared to parks, while there was a higher relative abundance of rats in parks. Our findings corroborate that greenness is associated with a higher abundance of wild rats, and that municipality rat complaints may underestimate the abundance of rats in greener urban areas. This study provides new insights on factors affecting relative rat abundance in cities and can guide policy makers and city planners how to minimize rat nuisance in the greener parts of cities. By taking these potential effects of urban greenness on rat abundance into account, measures can be taken that on the one hand maintain the beneficial effects of urban greening, but at the same time reduce the carrying capacity for rats.

Uncertified land abounds. The critical question is whether such land can provide security of tenure, access to finance, effective urban planning, and highest and best use. While much research contests the prospects and problems of conventional land title registration, the power of uncertified land is an issue rarely raised and, if done, hardly resolved holistically. Fundamentally still, economists, philosophers, urbanists and others continue to dispute such power, contending that certified and commodified land is the answer to urban problems. Such theoretical contests lead to the following bigger puzzles: (1) Do uncertified land tenure systems address questions of insecurity of tenure, access to finance, effective planning, and highest and best use, as claimed by the theory of ‘the commons in an age of uncertainty’? (2) Are the experiences of land title registration congruent with the theory of certified and commodified land? (3) Why do states pursue land title registration over other land policies? Thematic analysis of original data, collected between 2019 and 2023 in Bali, Indonesia, well documented as a place with an alternative land tenure system undergoing rapid commodification, helps to answer these questions. Our data seem to indicate that uncertified land can address the questions raised about security of land tenure, finance, effective planning, and highest and best use—prospects that elude certified and commodified land. The preference for the latter as the vision of land policy, we find, is rooted in political‐economic structures that favour, and are reproduced by, a transnational alliance of monopolists.

This study aims to obtain a composite index characterizing Bulgarian districts about their creativity by presenting results for the pre-pandemic. The composite index developed by Rodrigues and Franco (2019), use of quantitative method and multivariate statistical techniques have been used to answer this objective. From the data gathered primarily from NSI- The National Statistical Institute of Bulgaria, the results show that creativity is one of the pillars of economic growth, and financial resources and local and foreign investment for its development are still very limited. The government and cultural organisations supported initiatives to showcase the country's cultural diversity and historical significance. The creative sector, including design, arts, media, and technology started to be seen as a driving force for the country's economic growth. Startups and creative entrepreneurs are increasingly gaining weight, which has led to the creation of creative centers, and co-working spaces. Therefore, this study contributes to the intelligent application of creative cities' ideas in the creative industries and contemporary cities' management. [ABSTRACT FROM AUTHOR]

This paper bridges the gap between the literature on the pandemic's effects on mobility and the literature on the impact of low emission zones (LEZ). Using data for large European cities in the period 2018–2021, we examine whether LEZs may explain differences in the recovery patterns of traffic in European cities after the shock of Covid. Controlling for several city attributes, we examine whether LEZ cities are less congested before and after the pandemic in comparison to non-LEZ cities. LEZs may have been more effective in reducing congestion after the pandemic because the fleet renewal process has slowed down or, alternatively, LEZs may be a proxy of unobservable factors related with attitudes of governments and citizens toward a sustainable mobility. Our results validate the traffic-mitigating role of the LEZ after the Covid-19 pandemic, although such result only holds for the pioneering LEZ cities. Hence, the traffic-mitigating role of the LEZ after the Covid-19 pandemic seems to be related to unobservable attributes that influenced the early decision to implement a LEZ. In this regard, we also find that LEZs may have induced a change in local attributes related to sustainable mobility given that we do not find differences between LEZs decided at the local or regional level.

Texts recounting the careers of saints were foundational to Christian worship and historical construction in medieval Europe. They were also fluid, living works that evolved over time as individual saints' stories were revised, adapted, and retold. These texts changed in response to changing contexts in which they were used and understood. This article undertakes a case study to see how the evolution of one urban saint's legend reflects the history of that saint's city. Specifically, it analyzes the numerous Latin and vernacular texts produced between the mid-fifth and late twelfth centuries that recount the deeds of Saint Trophimus, first bishop of Arles. It argues that shifts in the saint's story reflect broad changes in the political, religious, and social life of Arles. It also demonstrates that the number of parties recounting the legend multiplied over time, and that dissonances within the story arose as these groups adapted the tale to their own interests.

This paper draws together elements of the academic literature on policy mobilities on the one hand, and on the 'digital turn' on the other. It argues that COVID‐19 accelerated the digitalization of everyday life asking we think through how those already existing informational infrastructures supporting the mobility of policies are continuing to evolve, as are the methods available for researching them. This has potential consequences for how cities practice policy comparison exchange, and learning and how these processes are studied. This paper sets out a three‐pronged schema to take seriously the intersection of policy mobilities and the digital. They are policy mobilities through the digital, policy mobilities produced by the digital and policy mobilities of the digital. It concludes by outlining fruitful areas for a future research agenda.

There has been increasing attention to legal and political contention concerning refugees and asylum seekers in cities. However, there are further opportunities to analyze the relationship between civil society litigation and state institutions in Global South cities. In this paper, I analyze civil society litigation to re-open Refugee Reception Offices (RROs) in South Africa. Primarily based on legal research, I argue that civil society litigation to re-open RROs in specific cities represents an advocacy strategy to contextualize national rights and policies within urban spaces. The paper contributes to broader discussions on civil society advocacy and rights and governance in cities. [ABSTRACT FROM AUTHOR]

This study examines the relation between local diversity configurations and policies in a selection of Dutch city case studies. Firstly, we identify distinct diversity configurations in Dutch cities, based on a quantitative analysis of 388 municipalities. Subsequently, we conduct a qualitative in-depth study of local policies on migration-related diversity in 10 cities representing specific diversity configurations, to assess the fit between the characteristics in some selected cities and the policy responses. Our study substantiates what has been described in the literature on the local turn in migration studies; the 'local dimension' of migration-related diversities and policies reveal a plurality of approaches rather than a one-size-fits-all local model. Differences in urban diversity configurations are reflected in urban policy in specific ways. We also found that inequalities and segregation mattered in terms of the problematization of integration and the choice of policy approach. Our analysis reveals a relationship or 'match' between specific urban diversities and specific urban policies. Based on these matches, we propose a fourfold typology of urban diversity policies. Thus, the article seeks to contribute to a more differentiated understanding of the multilevel complexity of diversities at the local level. [ABSTRACT FROM AUTHOR]

This study estimates the spatial changes in Minna's built-up areas. For change detection and urban growth analysis, the topographical map of Minna in 1972, the township map for 1979, and the satellite imageries covering 1986, 1996, 2006, and 2015 were all employed. These maps were georeferenced using ArcGIS 10.3. The study reveals as follows: 1972 (468.3 hectares); 1979 (893.7 hectares); 1986 (4,579.8 hectares); 1996 (5,205.4.5 hectares); 2006 (8,505.1 hectares); and 2015 (19,777.2 hectares). The land consumption rates were estimated as 0.0084, 0.0117, 0.0356, 0.0215, 0.0204, and 0.0273, respectively.We conclude that strategies birthed by systematic planning conclusions must guide cities.

This study extends the concept of granularity from firms to cities, examining how large cities influence national economic dynamics beyond their relative size. By applying Zipf's law, which describes the power law distribution of city sizes, we investigate the interplay between granularity and business cycles. Our aim is to test the granular hypothesis that large cities have a significant impact on the business cycle beyond their relative size. We analyze data from American and Brazilian cities between 2003 and 2019 assessing the granular residuals and their explanatory power. Our findings reveal that in the United States, the granular city size is three metropolitan areas or five counties when redefined. In Brazil, it equates to three municipalities. These results emphasize the substantial role large cities play in national economic fluctuations, suggesting that policy interventions that target infrastructure, education, and innovation in major urban centers could have widespread economic benefits. This paper's contribution to the literature is to highlight a spatial component of granularity not considered so far. [ABSTRACT FROM AUTHOR]

With an increasingly urbanized world, there is an urgent need to examine how cities may evolve and achieve sustainability. This paper systematically looks at the Greater Bay Area (GBA) and the Poyang Lake Region (PLR) in China to examine the spatial processes for insights into cities and urbanization, balancing the environmental and socio‐economic dimensions. A total of 226 805 cells are analyzed to unveil the relationship between sustainability changes in 2015–2019 period and urban form indicators, considering sociodemographic variables, geographical features, and city size as control variables. Two tree‐based machine learning models (Random Forest and XGBoost) are developed. This study provides evidence that a monocentric urban form and a high share of small activity clusters are not good for sustainability. For each urban form indicator, there is a non‐linear relationship with sustainability. The results of the machine learning models reconfirm the sustainability benefits of having a strong second activity cluster comparable to the largest one. When planning cities, some forms of land use buffering are desirable. There is also support for developing relatively large activity nodes and promoting compactness in urban form. Beyond urban form characteristics, the levels of urbanization, economic development, and population are still highly relevant. [ABSTRACT FROM AUTHOR]

Purpose: This study aims to investigate how the coupling of Material and Energy Flow Analysis (MEFA) with Life Cycle Assessment (LCA) under an urban metabolism (UM) perspective (referred to as the UM-LCA approach) can support the design, evaluation, and monitoring of urban-level circular strategies. For this purpose, we apply the UM-LCA approach to the urban area of Umeå (Sweden) by expanding the goal and scope of a recent MEFA study conducted by the authors of the article. Methods: The modeling combines MEFA with LCA and is performed both retrospectively and prospectively. The MEFA was performed in the prior study following a bottom-up approach to map and quantify material and energy flows in the urban system at the sectoral level. The quantified flows are used in the present study to construct the life cycle inventory (LCI) model of the urban system. The LCI model is first used as a basis of the retrospective LCA (rLCA), which is conducted to assess the environmental performance of the urban system with its sectors. The LCI model is then modified according to future scenarios and is used as a basis of the prospective LCA (pLCA), which is performed to assess the environmental implications of implementing circular strategies in the future. Results and discussion: The rLCA shows that the construction and household sectors are major drivers of environmental impacts in the urban system, with households being the largest contributors to 11 out of 12 analyzed impact categories. It also reveals the most impacting flows within these sectors, including food in households and steel in the construction sector. These findings indicate that the construction and household sectors and their most impacting flows should be prioritized in a circular strategy. Furthermore, the pLCA highlights that a future circular strategy promoting reductions in the material used in these two sectors could lead to higher reductions in all impact categories, ranging from 4.3 to 8.6%, than a strategy focused only on recycling, which could lead to reductions ranging from 0.2 to 1.2%. Conclusions: This study concludes that the UM-LCA approach has great potential to comprehensively analyze, both retrospectively and prospectively, the environmental performance of an urban system providing valuable insights that could support policy makers in designing, assessing, and monitoring urban-level circular strategies. However, further research should address identified limitations of the UM-LCA approach (e.g., limited available data, inability to consider social and economic aspects) to facilitate its applicability and enhance its comprehensiveness.

Background: Early childhood caries (ECC) is a multifactorial disease in which environmental factors could play a role. The purpose of this scoping review was to map the published literature that assessed the association between the Sustainable Development Goal (SDG) 11, which tried to make cities and human settlements safe, inclusive, resilient and sustainable, and ECC. Methods: This scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. In July 2023, a search was conducted in PubMed, Web of Science, and Scopus using tailored search terms related to housing, urbanization, waste management practices, and ECC. Studies that solely examined ECC prevalence without reference to SDG11 goals were excluded. Of those that met the inclusion criteria, a summary highlighting the countries and regions where the studies were conducted, the study designs employed, and the findings were done. In addition, the studies were also linked to relevant SDG11 targets. Results: Ten studies met the inclusion criteria with none from the African Region. Six studies assessed the association between housing and ECC, with findings suggesting that children whose parents owned a house had lower ECC prevalence and severity. Other house related parameters explored were size, number of rooms, cost and building materials used. The only study on the relationship between the prevalence of ECC and waste management modalities at the household showed no statistically significant association. Five studies identified a relationship between urbanization and ECC (urbanization, size, and remoteness of the residential) with results suggesting that there was no significant link between ECC and urbanization in high-income countries contrary to observations in low and middle-income countries. No study assessed the relationship between living in slums, natural disasters and ECC. We identified links between ECC and SDG11.1 and SDG 11.3. The analysis of the findings suggests a plausible link between ECC and SDG11C (Supporting least developed countries to build resilient buildings). Conclusion: There are few studies identifying links between ECC and SDG11, with the findings suggesting the possible differences in the impact of urbanization on ECC by country income-level and home ownership as a protective factor from ECC. Further research is needed to explore measures of sustainable cities and their links with ECC within the context of the SDG11. [ABSTRACT FROM AUTHOR]

AbstractPakistan is a developing country and its population is growing rapidly. The trend towards economic growth and satisfying the needs of the growing population is increasing daily. For this purpose, industrial activities, vehicle emissions, and household-related activities pollute the atmospheric environment and release different types of toxic gases. Particulate matter assessments (PM2.5 and PM10) were reviewed in different cities of Pakistan. Respectively, the PM2.5 evaluation was carried out in 15 cities, while the PM10 concentration was in 18 cities in Pakistan. According to the review, the highest concentrations of PM2.5 were 302, 211.97, 88, 163.63, 113.09, 110.81, 110.81, 139.43, 126.97, 107.68, 109.81, 172, 150, 66, 354, 43.9, 2305 µg/m3 in Lahore, Faisalabad, Karachi, Gujranwala, Multan, Vehari, Bahawalnagar, Okara, Pakpattan, Jehlum, Sargodha, Peshawar Quetta, Islamabad, Haripur, Mingora, and Mardan (Jalala). Specifically, the highest concentration of PM10 were 301, 568, 638, 160.5, 200, 384.15, 301.38, 311.61, 700 µg/m3 in Lahore, Faisalabad, Peshawar, Charsada, Karachi, Gujranwala, Multan, Rawalpindi, and Quetta. Only, these cities are the most polluted in the whole country and the concentration of PM2.5 was above the normal range those prescribed by the National Environmental Quality Standred (NEQS). Commonly, the main problem is the suspended particulate matter (PM2.5 and PM10) in the atmosphere. The increasing level of pollution leads to different types of problems such as respiratory problems, eye irritation, throat infections, asthma, and cancer, and it also increases the level of death ratio in the country. The main reason for PM is the burning of solid waste near cities; industrial emission, vehicular emission, lack of proper green belt and solid waste management are the main reasons for atmospheric pollution. Given the existing state of the air, urgent action is required to address the low air quality. [ABSTRACT FROM AUTHOR]

More than half of the world's population live in cities, and they have benefitted from the ecosystem services provided by urban biodiversity. International conventions like the Convention on Biological Diversity have provided recommendations on how to engage local governments and cities in the implementation of their strategic plans. In parallel, recognizing this, cities conserve, restore and enhance biodiversity in many practical ways. A list of general strategies adopted by cities is presented. The rich and diverse experiences of eleven cities, i.e. Abu Dhabi, Auckland, Durban, Edinburgh, Edmonton, Hyderabad, Los Angeles, São Paulo, Singapore, Toluca and Vitoria-Gasteiz, which have successfully conserved biodiversity in urbanized landscape across the globe, are shared. These cities have all applied the Singapore Index on Cities' Biodiversity as an evaluation and monitoring tool for biodiversity conservation efforts, in addition to using it innovatively for other purposes. Cities can play a pivotal role in ensuring that Target 12 of the Kunming–Montreal Global Biodiversity Framework will be achieved. Upscaling cities' models of success would require a worldwide concerted effort involving everyone, i.e. all levels of stakeholders. Mainstreaming of biodiversity into all sectors, including commercial, economic, financial, industrial and technological, and the incorporation of biodiversity into decision-making in urban planning and management would be a game-changer. This article is part of the theme issue 'Bringing nature into decision-making'. [ABSTRACT FROM AUTHOR]

Wetlands provide ecosystem services such as flood protection, improved water quality, and wildlife habitat, but are under attack in urban land-use conflicts in the Global South. This article presents two cases of local wetlands governance conflicts in Colombia (Humedal la Conejera, Bogotá, Cundinamarca) and Argentina (Laguna de Rocha, Esteban Echeverría, Gran Buenos Aires) to illustrate divergent pathways toward improved environmental governance via citizen pressures: the collaborative method (Bogotá) and the adversarial method (Buenos Aires). While existing scholarship on citizen-led regulation stresses the importance of collaboration between community organizations and the state, this article argues that adversarial tactics are also a key component of environmental governance. In both cases, citizen-led pressures led to increased enforcement of regulatory measures to restore wetlands and gain protected-area status. Citizen-led governance involved adversarial strategies such as marches, litigation, and shaming and blaming in the media, as well as collaborative strategies such as creating broad-based educational forums, working inside city government, and partnering directly with public institutions to set new policies. Against the backdrop of extensive collusion between elected officials and land developers, citizen-led subnational environmental governance has become the regulatory regime of last resort in urban Latin America.

In this article, I propose a cartographic approach to literature that privileges the study of personal itineraries through the city. More specifically, my proposal consists of tracing these itineraries and analyzing how they subvert the dominant narratives of the city. My hypothesis is that the representations that emerge from such an analysis allow for a reconceptualization of the city that dislocates and actualizes the hegemonic imaginaries of urban settlements. To demonstrate the insights that can flow from this approach, in this article I analyze the itineraries of Salvador Novo through Mexico City as depicted in La estatua de sal. In doing so, I trace the complex network of queer circuits in post-revolutionary Mexico and present a more holistic understanding of the city that corrects the dominant representations of the capital as hyper-masculine and heterosexual.

This paper builds on the expansion of urban ecology from a biologically based discipline—ecology in the city—to an increasingly interdisciplinary field—ecology of the city—to a transdisciplinary, knowledge to action endeavor—an ecology for and with the city. We build on this "prepositional journey" by proposing a transformative shift in urban ecology, and we present a framework for how the field may continue this shift. We conceptualize that urban ecology is in a state of flux, and that this shift is needed to transform urban ecology into a more engaged and action based field, and one that includes a diversity of actors willing to participate in the future of their cities. In this transformative shift, these actors will engage, collaborate, and participate in a continuous spiral of knowledge → action → knowledge spiral and back to knowledge loop, with the goal of co producing sustainable and resilient solutions to myriad urban challenges. Our framework for this transformative shift includes three pathways: (1) a repeating knowledge → action → knowledge spiral of ideas, information, and solutions produced by a diverse community of agents of urban change working together in an "urban sandbox"; (2) incorporation of a social–ecological–technological systems framework in this spiral and expanding the spiral temporally to include the "deep future," where future scenarios are based on a visioning of seemingly unimaginable or plausible future states of cities that are sustainable and resilient; and (3) the expansion of the spiral in space, to include rural areas and places that are not yet cities. The three interrelated pathways that define the transformative shift demonstrate the power of an urban ecology that has moved beyond urban systems science and into a realm where collaborations among diverse knowledges and voices are working together to understand cities and what is urban while producing sustainable solutions to contemporary challenges and envisioning futures of socially, ecologically, and technologically resilient cities. We present case study examples of each of the three pathways that make up this transformative shift in urban ecology and discuss both limitations and opportunities for future research and action with this transdisciplinary broadening of the field.

This article engages with the spatialities of platform urbanism by foregrounding where digital platforms are located in cities. Drawing on a geocoded data set of visible, material traces of platformization collected across neighborhoods in Toronto, Vancouver, and Montreal, we consider the influences that characteristics of urban built environments—including existing amenities, urban morphology, and area-level socioeconomic factors—have on platforms' locations. Through a Poisson regression of these variables, we find that the presence of existing urban amenities most strongly explains the locations of material traces of urban platformization on the cityscape at the city block scale. We position platforms themselves as a novel amenity class that extends emplaced utility and lifestyle functions to urban residents. In so doing, we contend that the platformization of urban landscapes constitutes a form of "splintering amenitization," wherein platformized urban amenities demonstrate spatial patterns of colocating with other, existing urban amenities in already amenity-rich areas to the exclusion of amenity-poor enclaves. This, we argue, is important because neighborhoods' abilities to attract amenities are central to how enclaves both position themselves and compete for status within urban spatial hierarchies.

Many universities are transforming campuses by responding to globally significant, locally specific, economic, political, and social imperatives. Some are implementing urban and regional transformations in higher education delivery to increase student access and diversity. Their success can depend upon infrastructures provided by other parties. Public transport is an example. Transit accessibility and equity affect quality of life, livelihoods, life course, and liveability in cities. Growing numbers of international studies consider factors shaping student travel to and from university campuses by public transport; fewer address local socio-spatial experiences of travel. Informed by debates about differential accessibility of suburban and city campuses, we examined student experiences at an Australian regional university undergoing transformation. We report on a study assessing multiple trips to and from two campuses to five destinations. Rich insights were drawn from experiences of antisocial behaviour, vulnerability, and sub-optimal service provision and reveal why some students think public transport is a mode of last resort. Universities and their stakeholders need to know more about student experiences of mobility. Such knowledge could inform tailored transport interventions and universities' willingness to encourage public transport providers to view their services as infrastructures of care.

The paper presents a field study analysing how pedestrians walked for leisure purposes in a familiar urban area, and why they walked as they did. Using mobile-based GPS, the walking trajectories of 44 participants were recorded, followed by the administration of a post-walk survey. Results show that participants gravitated towards five distinct paths that were similar in length (three shorter and two longer paths), yet observably different with respect to specific street features. Correspondingly, participants rated street features associated with these differences as factors that either attracted them towards, or repelled them away, from walking in specific streets.

The encounter between anthropology and history has great potential to illuminate marginalized social actors and the diverse power relations that were in play in the past, especially in the lives of urban Indigenous people. This article traces the trajectory of the growing interchange between anthropology and history and their different methodologies to document Indigenous history in the city. Researching Indigenous pasts in the urban environment poses particular challenges in confronting researchers with specific types of archival silences and cultural-political erasures. Triangulating diverse historiographic and ethnographic sources and perspectives in what I call "ethnography of the archives" can offer strategies for hearing the silenced voices of the urban environment of the past.

Excessive urban household water usage is a pressing global issue faced by many cities. This study aims to develop a concise yet encompassing taxonomy of water demand management strategies, offering a clear and organized framework that enables comparison and evaluation of strategies, informs policy and decision-making, and fosters an interdisciplinary approach to water demand management research. An analytical literature review using grounded theory and hermeneutics was conducted to find key concepts and constructs, identify relationships among them, and synthesize these elements into a coherent framework. The resulting taxonomy presents a classification of demand management strategies into five categories: Psychological, Educational-Communicational, Technological, Economical, and Coercive-Legal.

While India's low female labor force participation in urban areas is often attributed to its demographic and labor market characteristics, education, and cultural aspects, attention is not paid to the labor market opportunity structure limiting women's labor market participation. We examine the role of transport infrastructure in gendergap in labor force participation and its variations by gender-norms across communities. Using India Human Development Survey and city-level data on transport infrastructure, the causal effects of differential employment status of women and men are related to size and quality of transport in twelve Indian cities. Interaction effects are explored to understand varying impacts of transport on employment by gender-context in communities. We find that an improvement in the size and quality of transportation infrastructure improves women's labor market participation more than that of men. In gender egalitarian communities, stronger positive effect of transport on female labor and reduction of gender gap in employment. Along with generation of new job opportunities suitable for women, it is important to encourage a gender-friendly institutional and social fabric to allow women to connect to new jobs. Using a novel data, the paper highlights the importance of ostensibly gender-neutral development policies for shaping gender inequalities in outcomes. [ABSTRACT FROM AUTHOR]

This article bridges comparative constitutional law with research inspired by city leadership and the opportunities that technology brings to the urban environment. It looks first to some of the causes of rapid urbanization and finds them in the pitfalls of antidiscrimination law in federations and quasi-federations such as the United States and the European Union. Short of achieving antidiscrimination based on nationality, the EU has experimented with data privacy as an identity clause that could bring social cohesion the same way purportedly freedom of speech has done in the US. In the City however, diversity replaces antidiscrimination, making cities attractive to migrants across various walks of life. The consequence for federalism is the obvious decline of top-down or vertical, state-based federalism and the rise of legal urbanism whereby cities establish loose networks of cooperation between themselves. These types of arrangements are not yet a threat to the State or the EU but might become such if cities are increasingly isolated from the political process (e.g., at the EU level) and lack legal means to assert themselves in court. City diversity and openness to different cultures in turn invites a connection to new technologies since unlike antidiscrimination that is usually strictly examined on a case-by-case level, diversity can be more readily computed. Finally, the article focuses on NYC and London initiatives to suggest a futuristic vision of city networks that instead of using social credit score like in China, deploy data trusts to populate their urban environments, shape city identities and exchange ideas for urban development..

Birds are a prominent component of urban biodiversity yet many species, particularly forest-dependent birds, are vulnerable to landscape transformation. We examined the relative influence of three factors that potentially influence forest bird communities in residential areas of Melbourne, Australia: (i) local habitat attributes; (ii) types of land use; and (iii) biotic interactions with an aggressive native species, the noisy miner (Manorina melanocephala). We also investigated characteristics of urban sites that contribute most to landscape-level diversity of forest species. We systematically surveyed forest birds at 300 sites in a range of urban land-uses; with sites clustered in 30 landscapes representing gradients in housing cover and tree cover. Composition and richness of forest bird communities differed among land-use types: sites with greater cover of native canopy trees had a distinct and richer avifauna. However, a pervasive influence on communities was the relative abundance of the noisy miner, a native species that aggressively excludes small insectivores. Sites in native vegetation made the greatest contribution to landscape-level richness of forest birds, but also were negatively influenced by noisy miner occurrence. The dominance of the noisy miner poses a challenge for conservation because actions to improve urban habitat for forest species may also benefit this aggressive species. Conservation of forest birds will depend on larger forest tracts, fringing residential areas, which are less suitable for the noisy miner and serve as potential source populations for forest species. Within residential areas, enhancing understorey complexity with native shrubs and mid-storey will help improve urban habitats for forest birds. [ABSTRACT FROM AUTHOR]

This paper explores what needs to be done to better address the growing and substantial inequalities in the UK and how the 'Levelling Up' policy that seeks to address them could be improved. It argues that a much longer-term vision and a sharper, cross-government focus on fewer challenges is required to make a more tangible impact. Four key findings are identified: a focus on health and education is fundamental for our social and economic prosperity; there is a need for greater devolution of power, with transparent and robust accountability; an open, nationwide knowledge base to share what works and what does not, and the lessons learned from innovative pilots, is required; and a more holistic approach is needed to support businesses and provide them with better-quality support. This paper argues that without these issues being taken into consideration, the lives and well-being of our disadvantaged citizens, our children and our economy will continue to worsen. It concludes that making economic development a statutory function, putting it at the very heart of our public services, is needed to ensure that the levelling up outcome is achieved.

The location of tourist properties is a fundamental aspect in the determination of price, but in cities with dense and efficient public transport systems, the location being in the periphery can offer alternative advantages to central locations (such as better accessibility by private vehicles). This study analyses how the price of tourist housing is influenced by the characteristics of the accommodation itself and its location, using a hedonic pricing regression model estimated by ordinary least squares (OLS) in two periods of time: the high season (October 2022) and the low season (February 2023). The obtained results suggest that the characteristics of the properties, the local environment and the elements in the area influence the price of tourist accommodation. Similarly, the proximity to public transport stations and stops has a relevant influence on the choice of tourist properties. This latter factor is highly important for designing public policies that favour a denser public transport network in peripheral areas of the city. This would increase the number of tourist properties in these areas further away from the centre and, therefore, the number of reservations. In turn, the income of these more vulnerable areas would improve together with the social cohesion of the municipality. [ABSTRACT FROM AUTHOR]

To date, more and more European cities are systematically working to expand the proportion of their street network with a speed limit of 30 km/h. This paper endeavored to assess the effectiveness of city-wide 30 km/h speed limits in Europe. In an effort to condense research outputs, a quantitative approach along with qualitative assessments were implemented. This study described the changes in safety, environment, energy, traffic, livability, and health before and after the phased implementation of city-wide 30 km/h speed limits. The systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Results from 40 different cities across Europe, including Brussels, Paris, and Zurich, indicated that reductions in speed limits improved road safety by decreasing the likelihood of crash risk and the severity of crashes that do occur. On average, the implementation of 30 km/h speed limits in European cities demonstrated a 23%, 37%, and 38% reduction in road crashes, fatalities, and injuries, respectively. Lower speed limits also yielded environmental benefits, with emissions decreasing on average by 18%, noise pollution levels by 2.5 dB, and fuel consumption by 7%, indicating enhanced fuel efficiency and reduced environmental impact. Encouraging citizens to embrace walking, cycling and utilizing public transit services can further contribute to a safer and environmentally sustainable urban environment. [ABSTRACT FROM AUTHOR]

Green vegetation may protect against heat-related death by improving thermal comfort. Few studies have investigated associations of green vegetation with heat-related mortality in Latin America or whether associations are modified by the spatial configuration of green vegetation. We used data from 323 Latin American cities and meta-regression models to estimate associations between city-level greenness, quantified using population-weighted normalized difference vegetation index values and modeled as three-level categorical terms, and excess deaths from heat (heat excess death fractions [heat EDFs]). Models were adjusted for city-level fine particulate matter concentration (PM2.5), social environment, and country group. In addition to estimating overall associations, we derived estimates of association stratified by green space clustering by including an interaction term between a green space clustering measure (dichotomized at the median of the distribution) and the three-level greenness variable. We stratified analyses by climate zone (arid vs. temperate and tropical combined). Among the 79 arid climate zone cities, those with moderate and high greenness levels had modestly lower heat EDFs compared to cities with the lowest greenness, although protective associations were more substantial in cities with moderate versus high greenness levels and confidence intervals (CI) crossed the null (Beta: -0.41, 95% CI: -1.06, 0.25; Beta -0.23, 95% CI: -0.95, 0.49, respectively). In 244 non-arid climate zone cities, associations were approximately null. We did not observe evidence of effect modification by green space clustering. Our results suggest that greenness may offer modest protection against heat-related mortality in arid climate zone Latin American cities.

Heating and cooling in buildings accounts for over 20% of total energy consumption in China. Therefore, it is essential to understand the thermal requirements of building occupants when establishing building energy codes that would save energy while maintaining occupants thermal comfort. This paper introduces the Chinese thermal comfort dataset, established by seven participating institutions under the leadership of Xian University of Architecture and Technology. The dataset comprises 41,977 sets of data collected from 49 cities across five climate zones in China over the past two decades. The raw data underwent careful quality control procedure, including systematic organization, to ensure its reliability. Each dataset contains environmental parameters, occupants subjective responses, building information, and personal information. The dataset has been instrumental in the development of indoor thermal environment evaluation standards and energy codes in China. It can also have broader applications, such as contributing to the international thermal comfort dataset, modeling thermal comfort and adaptive behaviors, investigating regional differences in indoor thermal conditions, and examining occupants thermal comfort responses.

BackgroundPublic health experts have urged governments around the world to regulate newly legalized cannabis as they do alcohol to effectively and efficiently protect health. However, research evaluating the alignment of alcohol and cannabis policies is sparse. We assessed similarities and differences in local alcohol and cannabis control policies across California, and characterized localities adopting distinct policy approaches.MethodsUsing standard legal epidemiologic techniques, we collected and coded local alcohol and cannabis control policies relevant to public health for 12 California counties and all incorporated cities within them (N=241). We assessed whether localities were equally stringent on alcohol and cannabis policies by comparing overall restrictiveness (summed policy scores) and 9 specific provisions that applied to both substances. We captured distinct local alcohol-cannabis policy approaches using latent class analysis, and examined this classification in relation to local demographic, socioeconomic, political, and retail market characteristics.ResultsAll 241 localities permitted alcohol sales, while 71% banned cannabis sales. Among those that did not ban cannabis sales, more stringent alcohol policy scores were associated with more stringent cannabis policy scores (linear regression coefficient: 0.16 [95% CI: 0.07, 0.25]). Local governments rarely adopted the same provisions for alcohol and cannabis (e.g., limits on hours of sale, advertising restrictions), and only two regulated the co-location of cannabis and alcohol outlets. Localities that were restrictive on alcohol yet permissive on cannabis (12%) were more urban, politically progressive, and had more low-income and racial/ethnic minority residents. Localities that were more permissive on alcohol and restrictive on cannabis (51%) were more socioeconomically advantaged.ConclusionWe found few similarities between local alcohol and cannabis control policies. California's experience suggests that, as governments around the world legalize cannabis, lessons learned from regulating alcohol are not routinely applied to cannabis, particularly in communities distinguished by high social and economic advantages.

Due to the increasing impacts of climate change on flood management, it is vital to implement effective flood mitigation measures. Economic factors significantly influence the feasibility and speed of these implementations. Evaluations must go beyond just the implementation costs. This paper introduces tools and methods for incorporating environmental economics into flood risk management at various scales, from urban areas to entire river basins. Comprehensive analysis should include social, environmental, direct, and indirect factors. Despite the variability in flood mitigation costs across different economies, the methods discussed are highly adaptable. Data limitations for appraisal tools like Multicriteria Analysis (MCA) and Cost-Benefit Analysis (CBA) can be addressed through expert judgment, qualitative assessment, or using GDP-proportional data for cost estimation. This approach utilizes databases from experienced countries, making the methods adaptable to different contexts.

Abstract This article examines the enduring iconicity, multifaceted functions, and changing meanings of the Astor Hotel in Tianjin—one of the first international hotels in modern China—from the mid-19th century to the 21st century. Originally built more than 150 years ago, the Astor Hotel still stands exactly where it did in the former British Concession in Tianjin. This hotel was not only a venue boasting Tianjin’s most expensive accommodations but also a crucial site where politics, technology, economics, social, and cultural changes intersected and developed in its treaty port incarnation. Moreover, the expansion of the Astor Hotel evolved along with the development of Tianjin from a hypercolonial city to a Chinese-run metropolis. Shortly after the Communist Revolution in China, its ownership was overtaken by the Tianjin Municipal Government. Following a sequence of major renovations and commercial relaunches in the 1990s, the Astor Hotel was restored and reconstructed as an emblem of Tianjin’s historical status as an international and cosmopolitan city in China. Both continuity and changes will be emphasised in the discussion of the Astor Hotel’s history, as well as its multiple functions and shifting symbolic significance.
