Unveiling the spatially varied nonlinear effects of urban built environment on housing prices using an interpretable ensemble learning model

The relationship between urban built environment (UBE) and housing prices manifests as complex, exhibiting significant nonlinearities and spatial heterogeneity that remain inadequately understood. Taking Shanghai as a testbed, this study employs a novel ensemble learning approach, augmented by Bayesian optimization and Monte Carlo simulation, to decipher the intricate and nonlinear impacts of UBE factors on housing markets across diverse urban geographies. Our analysis unveils substantial spatial variations in how transit accessibility, amenities, residential density, and green/blue spaces influence real estate values. Proximity to metro stations and bike-sharing facilities exerts a more pronounced positive effect than bus stops. Moreover, residents in central areas demonstrate a higher willingness-to-pay for public service amenities, while those in outer suburbs prioritize access to public transportation infrastructure. Intriguingly, it invokes an optimal threshold range of urban density for properties in new cities, thereby increasing the vitality and dense socio-economic networks. Furthermore, the sprawling suburbs have identified an adverse economic impact of large conservation green/blue spaces. These insights can guide policymakers in crafting spatially-tailored strategies that harness localized built environment drivers to catalyse equitable and prosperous urban development. Tailored policies informed by this spatially explicit understanding of nonlinear built environment-housing interactions can foster more sustainable, liveable, and inclusive cities.

Soundscapes in Urban Green Spaces of a Megacity Across an Urban–Rural Gradient: A Case Study of Shanghai

Urban soundscapes are valuable indicators of urban biodiversity and ecosystem health. This study investigated the spatial and temporal characteristics of soundscapes in megacity green spaces and their relationship with the urban environment. An acoustic index was formulated and calculated using long-term data from Shanghai’s urban green spaces. The results show a significant increase in the acoustic index during spring and summer, peaking during these periods, while a decrease was observed from December to February, dominated by abiotic sounds. Diurnal variations indicate a rapid increase in the acoustic index at sunrise, reflecting heightened avian activity during the dawn chorus. Human interference in the urban center limited acoustic activity, whereas the outer suburbs, with their more natural environments, supported greater acoustic richness.

Commuting behaviors response to living and working built environment: Dissecting interaction effects from varied supply and demand masses

Most developed megacities have experienced poly-centralization and suburbanization, leading to job-housing mismatches and negative outcomes such as increased commuting distances and frequencies. Recognizing the scarcity of structural analysis concerning the attractiveness of commuting's geographic endpoints, this study examines the diverse impact of the built environment at living and working locations on commuting flows, considering various supply-demand masses and distance levels. Utilizing a Gradient Boosting Decision Tree (GBDT) model, the study highlights the importance of job-housing ratio, POI diversity, and subway station proximity in employment locations, while informal area rates and subway proximity remain significant in residential locations. A three-dimensional analysis further indicates that achieving a perfect job-housing balance in megacities remains a dream, with each area presenting unique challenges requiring tailored solutions beyond a one-size-fits-all approach. Potential policies, such as planning large residential areas in the inner suburbs and upgrading convenient infrastructure in the outer suburbs, are proposed. Furthermore, with the uncovered distinct interaction effects of built environment on commuting behavior across various masses and distances, common perceptions related to mixed-use land and the role of informal settlement, are critically challenged. This extends our understanding of sustainable urban system design and provides references for planning policies.

Classified Spatial Clustering and Influencing Factors of New Retail Stores: A Case Study of Freshippo in Shanghai

The diversified innovative strategies adopted by the new retail format in urban spaces have significantly driven retail transformation and innovation. The combination of online platforms and physical stores provides a substantial advantage in market competition. This paper takes “Freshippo”, a typical representative of China’s new retail, as an example. Based on multi-source data and using tools such as GIS spatial analysis, statistical analysis, and geographical detectors, this study comprehensively examines the spatial clustering characteristics and influencing factors of Freshippo physical stores in Shanghai. The findings show that Freshippo has significantly expanded in the Shanghai fresh food market by innovatively opening various types of stores. However, there are substantial differences in the proportions of different types of stores, with 94% of the stores having online retail capabilities. Each offline store in the new retail format presents a multi-level “complementary” spatial distribution feature across the urban space, with distinctive clusters in the urban central districts, urban periphery areas, and outer suburban districts. The radiation range of logistics and distribution services exhibits characteristics of “central agglomeration and multi-point distribution”, providing residents with diverse and accurate services. Additionally, the comparison of multiple model results shows that the location selection of various types of new retail stores is significantly influenced by multiple factors, especially the nonlinear amplification effect of factor interactions on store agglomeration. These findings provide an important scientific reference for understanding the development of new retail formats and offer new ideas that promote the transformation and innovation of the retail industry, thereby achieving sustainable development.

Study on the Strength of Rural Tourism Operators’ Willingness to Carbon Offset and Its Influencing Mechanisms

Tourism operators generate carbon emissions during their operations, and their environmental responsibility behaviors, such as carbon offsetting, significantly impact the ecological environment of tourist sites. Understanding the operators’ willingness to engage in carbon offsetting and the factors influencing this willingness is crucial for achieving the “dual carbon” goals and promoting sustainable growth in China’s tourism sector. This study collected 746 offline questionnaires from operators at rural tourism sites across 100 counties and districts in Jiangxi Province. It empirically analyzed their willingness to participate in carbon offsetting, comparing various factors such as the strength of willingness, spatial differences, and distinctions between all-for-one tourism counties and non-all-for-one tourism counties, as well as suburban, outer suburban, and remote tourism sites. Using the value–belief–norm theory and the theory of planned behavior, a structural equation model was developed to comprehensively examine the operators’ willingness and its influencing mechanisms. The structural statistical analysis revealed that the integrated model effectively predicted rural tourism operators’ willingness to participate in carbon offsetting. The results showed that, except for Hypothesis 6, all suggested correlations between the variables were significant. Value perception had a significantly positive effect on participants’ desire to engage in carbon offsetting. This research provides various theoretical and practical implications for local authorities regarding rural tourism operators, advancing the incentive for carbon offsetting and sustainable tourism development.

Geographic inequalities in park visits to mitigate thermal discomfort: A novel approach based on thermal differences and cellular population data

Climate change-intensified urban warming has brought attention to urban parks’ spatial allocation due to their cooling effects. However, conventional accessibility assessments of park cooling effects consider temperature and size, overlooking critical factors such as thermal comfort and supply and demand differences in thermal environments, which more accurately represent public thermal stress. We developed a multimode Gaussian-based Huff three-step floating catchment area method based on thermal stress differences between population locations and parks. This method integrates thermal comfort and cellular population data to assess the spatial mismatch between the supply and demand for park cooling services in Shanghai. Our findings show that most central and developing urban areas have excellent park cooling accessibility. However, considering population demand, central Shanghai requires improved internal park planning to enhance the cooling supply. In contrast, Shanghai's suburban areas exhibit significant supply-demand imbalances, especially in the south and southeast; they require an enhanced cooling supply through planning interventions. Incorporating thermal comfort differences into calculations shifts the highest per capita cooling supply area from the outer suburbs to the suburbs, substantially reducing areas with high demand but low supply. Our novel analytical approach to assessing park cooling accessibility can assist policymakers in developing precise climate adaptation strategies.

Community Functions of Schools and Municipal Support of Schools on the Continuum of the Rural Periphery – Town

Abstract The article compares the community functions of schools and the support to schools from the municipality representatives and community depending on the location of the school – in peripheral or semi-peripheral rural areas, rural small towns, outer suburbs and also in towns, i.e., at various distances from the town. It is based on controlled interviews with school headmasters and mayors of the respective municipalities and on the collection of information from annual school reports and school inspection reports. A total of 57 schools of two districts in the south-west of Czechia were evaluated. The assumption that complete rural schools in peripheries have the greatest community functions was confirmed; but complete rural schools in semi-peripheries also received similar assessment. However, a fully functioning rural "community school" was not found in the case study area. Schools in towns show weak community functions, because community functions in towns are provided by other institutions and facilities.

Prison expansion in the plains grasslands: Coloniality, ecological injustice and carceral sprawl

This article examines the politics of prison siting on contaminated land within an endangered ecosystem in Australia, contributing to the literature on carceral geography and the burgeoning field of abolition ecology. I argue that prisons materialise in the landscape through processes of dispossession, environmental degradation and value extraction that enclose Indigenous lands for caging populations cast as ‘surplus’ to settler racial capitalism. The primary focus is the interface between prisons and the Victorian Volcanic Plain grasslands at a site called Ravenhall, a former military testing site that has been remade as a ‘prisons precinct’ and native grasslands reserve on Bunurong country in the outer Western suburbs of Melbourne. I investigate the history, ecology and political economy of prison-building at this site, unearthing the assemblage of living and nonliving entities involved in the construction of carceral geographies, and the meaning-making that guides planning and conservation processes. Rather than simply protecting and enhancing the biodiversity of the plains grasslands, neoliberal conservation practices at Ravenhall facilitate carceral development by generating more visible and ‘substitutable’ natures to gloss over the socially and ecologically toxic realities of prisons. The analysis reinforces the role that carceral geographies play in reproducing structured racial-environmental vulnerabilities and the importance of challenging sprawling prison developments as part of decolonial, abolitionist and ecological justice struggles.

Resisting the heat wave: Revealing inequalities in matching between heat exposure risk and healthcare services in a megacity

Climate warming and the growing urban heat island effect are exacerbating the unequal public health crisis in megacities, and thus it is important to assess the equity of matching relationship between the healthcare services and the heat exposure risk. We selected 255 census units in Tianjin city for the study, and calculated a heat exposure index based on the universal thermal climate index (UTCI) and constructed a comprehensive urban healthcare services evaluation system to measure the degree of mismatch between the two. The results showed the following. (1) The heat exposure risk and healthcare services followed an increasing pattern from the Outer suburb area (OSA) to the Metropolitan development area (MDA) and then to the Main urban area (MUA). (2) The overall imbalance in matching was low in the OSA, whereas the healthcare services were relatively insufficient in the MDA, and the heat exposure risk and healthcare services were relatively balanced in the MUA. (3) The degree of matching between the core and peripheral parts of the MUA was severely polarized, with an overall pattern of excess healthcare in the core area and a high risk of heat exposure in the peripheral areas. The results can provide effective guidance for rationalizing the allocation of healthcare resources from a heat exposure perspective, and provide a policy basis for risk management and fund investment.

A scalable combinatorial benders decomposition for the Stochastic Dial-a-Ride Problem

Nowadays, Demand-Responsive Transport companies can help the elderly or disabled citizens in their everyday journeys as well as provide an important link between big cities and their outer suburbs. In practice, many of those trips are scheduled in advance but many others are asked on the fly (online) by the users while the drivers are already on their routes. To answer those online requests, dispatching centers often rely on fast heuristics based on some myopic objectives. However, this deteriorates the flexibility of the dispatch over time. This paper shows the potential of a thorough optimization of the planning of the vehicles at the start of the day under the hypothesis that the transport company is able to forecast the requests that will arrive during the service. Our objective is to design an initial set of routes for the vehicles that maximizes the expected acceptance rate of future requests, since the ones scheduled in-advance are mandatory. In this prospect, we propose a Combinatorial Benders Decomposition framework to solve the so-called Stochastic Dial-a-Ride Problem. A key ingredient for the success of this solver is the use of a clustering-based initialization of the Master Problem. The computational results show the effectiveness of this approach when applied to instances extracted from the literature as well as from actual services provided by Padam Mobility, an international company in Shared Mobility Systems. The proposed method provides a substantial performance gain though traditional heuristics are kept to manage online insertions afterward.

Planning local centres in outer suburbs – The need for a proactive approach towards planning in post-socialist Poland

Chaotic post-socialist suburbs need retrofitting through planning a system of local centres. The paper is aimed at recognizing the orientation of recent suburban planning in Poland through a focus on centres and identifying conditions for and examples of a proactive approach to planning local centres. The hierarchy of centres and the set of functions assigned to them is important since it could prevent the dispersion of public facilities and strengthen the potential of higher-order centres. Documents subjected to analysis encompassed spatial policies of 27 suburban municipalities included in the Functional Area of Warsaw. The Polish spatial planning system neglects centres as a category of functional, economic, and social space, leaving municipalities complete freedom in planning them. The study proved that a system of local centres should become an urban planning standard since it helps municipalities locate public functions more reasonably. A vision of local centre development is rarely based on rational premises. The Polish case shows that in outer suburbs, a proactive approach to LC planning that involves designing a desired future and then inventing ways to create that future state is still a long way off.

AED Inequity among Social Groups in Guangzhou

Automated external defibrillators (AEDs) are regarded as the most important public facility after fire extinguishers due to their importance to out-of-hospital cardiac arrest (OHCA) victims. Previous studies focused on the location optimization of the AED, with little attention to inequity among different social groups. To comprehensively investigate the spatial heterogeneity of the AED inequity, we first collected AED data from a WeChat applet. Then, we used the geographically weighted regression (GWR) model to quantify the inequity level and identify the socio-economic status group that faced the worst inequity in each neighborhood. Results showed that immigrants of all ages suffer a more severe AED inequity than residents after controlling population and road density. Immigrants face more severe inequity in downtown, while residents face more severe inequity in the peripheral and outer suburbs. AED inequity among youngsters tends to be concentrated in the center of each district, while inequity among the elderly tends to be distributed at the edge of each district. This study provides a new perspective for investigating the inequity in public facilities, puts forward scientific suggestions for future AED allocation planning, and emphasizes the importance of the equitable access to AED.

Developing an Urban Environment Examination System by Incorporating Construction, Economic, Environmental, Cultural and Development Dimensions

The sustainable development goals (SDGs) suggest sustainable cities and communities (Goal 11) as inclusive, safe, resilient, and sustainable human settlements. However, existing efforts in urban sustainability have mainly focused on ecological and environmental sustainability, with little attention paid to development, economic, and cultural sustainability. Moreover, a lack of adaptability is a barrier to cross-nation or cross-region implementation of many urban sustainability frameworks due to diverse urban contexts. Furthermore, most studies have developed sustainability frameworks and guides only for one-time assessments and the progress of urban sustainability has been neglected. Improving urban sustainability by considering multiple dimensions and local adaptability through dynamic assessment remains a question. Therefore, this study aims to develop an urban environment examination system (UEES) framework that includes construction, economy and industry, environment and resource, municipal and cultural facilities, and development potential dimensions. The UEES framework consists of 31 indicators associated with critical information (i.e., reported by the statistical yearbooks) from different levels of government in China. An annual update of statistical data ensures the availability of dynamic data, allowing urban managers and decision makers to regularly track urban sustainability. Furthermore, the UEES framework was applied to Qingdao, an urbanizing city in China, to examine the feasibility of the UEES framework. The results indicate that well-urbanized districts could perform better in terms of overall sustainability (e.g., Shinan, Shibei, Laoshan, Chengyang), while districts in suburban and outer suburban areas had lower urban sustainability levels. However, well-urbanized districts could not perform better in all dimensions than suburban and outer suburban districts. Moreover, the transition from less-urbanized to well-urbanized districts could lead to environmental deterioration and economy deceleration (if industries are not well upgraded), but culture and development sustainability can be improved. Overall, this study provides a methodological framework that prioritizes comprehensiveness and local adaptability to perform regular urban environment examinations for urban sustainability in China and provides a reference for urban sustainability improvement by identifying aspects with low scores in Qingdao, China.

A Ward Level Economic Topography of Sixteenth-Century Coventry

ABSTRACT Subsidy rolls of the 1540s and 1560s from the collection of Thomas Gregory, Coventry city clerk from 1528 to 1570, provide relative comparisons among Coventry’s wards over time. The various wards remained fairly consistent in relative wealth during the sixteenth century, and despite more diverse markets in the latter part of the century textiles still remained important. The central wards were the wealthiest, and wealth decreased moving towards the suburbs. The outer wards and suburbs were not necessarily poor, they just held few of the wealthiest merchants. The suburban wards of Spon and Gosford benefited from the growth of cap making. The incredibly wealthy wool and cloth merchants disappear by the mid-sixteenth century, but there is clear retention of the class of moderately wealthy gentry and merchants.

Out in Suburbia: Associations between residential location, mental health, and community connectedness among LGBTQ Australians

ABSTRACT This article critically examines the contemporary applicability of homonormativity in understanding LGBTQ experiences in outer suburban Australia. Representing a departure from urban-rural dichotomies in queer geographical research, this study enriches our understanding of LGBTQ life in suburban areas. Drawing on a comprehensive national survey encompassing 6835 LGBTQ adults in Australia, the research provides novel quantitative insights into the geographic distribution of LGBTQ mental health and wellbeing outcomes. Contrary to assumptions of suburban privilege, the article challenges the notion of homonormativity in the suburbs, shedding light on the unique challenges faced by LGBTQ people in these areas. Findings reveal that LGBTQ people in outer suburban Australia experience higher psychological distress and suicidal ideation compared to their inner suburban and rural counterparts. Additionally, they report lower levels of connection with LGBTQ communities, indicating a dearth of supportive resources in these areas. These insights have crucial policy implications, advocating for changes that foster diversity and inclusion in outer suburban areas. By emphasizing the distinct experiences of LGBTQ individuals in these settings, the research underscores the necessity for targeted interventions and support. This work extends beyond conventional urban-centric studies, offering valuable insights to inform policies, advocacy efforts, and community support initiatives for LGBTQ people in suburban environments.

Forever underground, forever black

Because it has been integral to the history and marketing of Bandung death metal, the satellite town of Ujung Berung aka Ujungbronx, in Bandung’s outer southeastern suburbs, has become a revered and romanticized myth throughout all of Indonesia’s underground scenes. The Indonesian underground constitutes the mythscape or page where alternative myths are promulgated, expanded, debated, opposed, or reimagined. While the governing myth of Ujung Berung scene as paramount is widely accepted in West Java province, it is accepted somewhat reluctantly, and with mild criticism, in the East Javanese and Jogjakarta scenes. However, in Surabaya, there is a recognition that the moment when the governing myth could have been overthrown, at least within East Java, is long past. History belongs to the victors.

Heritage, resistance and dissonance: reconstructing Pentridge in a prison tourism theme park

ABSTRACT Pentridge Prison was established in 1851 in the Melbourne outer suburb of Coburg in the state of Victoria, Australia. Decommissioned in 1999, the site is marked by 150 years of white colonial violence, trauma, incarceration and death. Twenty-four years on, it has been repurposed to include a mix of residential and commercial developments. More recently, Art Processors have been contracted by the developers to curate new Pentridge tours and visitor experiences. This article will observe how the institutional histories of Pentridge have been curated and represented through the on-site redevelopments and tours. Autoethnographic methods are deployed to document representations of social memory at the site. The framework of hauntology assists to elucidate the affective consequences of erasing landscapes marked by trauma and state-sanctioned violence. The result is a site defined by a deep sense of dissonance, where attempts to memorialise traumatic events, violence and death, are undermined by proximity to what can only be characterised as a prison tourism theme park. Ultimately, Pentridge Prison highlights the highly political process of repurposing penal sites and memorialising difficult histories carry profound implications for addressing contemporary injustices associated with imprisonment.

Mapping property redevelopment via GeoAI: Integrating computer vision and socioenvironmental patterns and processes

Domain knowledge of social and environmental sciences is generally derived from less structured small data and/or small models. The integration of deep learning with socioenvironmental and geographical patterns and processes is still in an early phase. This study proposes a flexible framework that synthesizes computer vision with patterns and processes of geographical phenomena (e.g., urban redevelopment) via deep convolutional neural networks and spatiotemporal neighborhoods, respectively. Meanwhile, undesirable visual cues (e.g., temporary objects such as cars) cause false alarms in urban change detection. Thus, a masked deep pyramid similarity model (i.e., the computer vision model) is proposed to minimize the negative impact of nonbuilding changes. This pipeline has robustness against obfuscation of undesirable street scene changes and elasticity of geographical knowledge representations in mapping property redevelopment. This model is reproducible and adaptable due to the wide availability of SVI and flexibility of the framework. The results suggest that the domain-driven rules and nonbuilding change masking mechanism can significantly increase the accuracy of a computer vision model. We also find that urban redevelopment should be understood as a locally tuned back-to-the-city process with weak replicability. Hybrid gentrification (i.e., the combination of “seesaw” gentrification and continuous gentrification) is observed globally with local variations. Takeaway for practiceFirst, the population of those affected should be carefully identified and the benefits of gentrification need to be redistributed on a larger scale. For Auckland, decision-makers should not divert attention away from low-income tenants in outer suburbs that slipped below the radar of local government and scholars. Second, more attention should be given to less resourcing neighborhoods in constantly gentrifying neighborhoods when governments formulate and implement housing subsidy policies. Locally, incessant redevelopment in Auckland CBD, New Market and Remuera, etc., should be contained.

Assessing the Potential for Developing Innovation Districts at the City Scale by Adapting a New Sustainable Entrepreneurial Ecosystems Method

Excellent previous case studies of innovation districts have provided a foundation for the integration of innovation and urban development. However, few researchers have evaluated the potential for developing innovation districts in inner city spaces. In this study, taking Qingdao as an example, the adaptive cycle theory was combined with entrepreneurial ecosystem theory to form a sustainable entrepreneurial ecosystem (SEE) framework, including the three criteria of conditions, outputs, and outcomes. This framework allows for the effective identification of key factors and areas within cities that influence the development of innovation districts. The results showed that the potential for developing innovation districts showed a concentric trend, i.e., higher in the downtown, highest in the suburbs, and lowest in the outer suburbs. Comparative analysis revealed that innovation sources were a key factor in the development of Qingdao’s innovation districts. In terms of cluster analysis, the northern and southwestern clusters in the suburbs were in the conservation (K) phase, and the eastern and downtown clusters were in the exploitation (r), suggesting that the former was the preferred location for innovation districts. This study facilitates the establishment of site-specific innovation districts at key locations to enhance the success of decision making.
