Reliable data on slums or deprived living conditions remain scarce in many low- and middle-income countries (LMICs). Global high-resolution maps of deprived areas are fundamental for both research- and evidence-based policies. Existing mapping methods are generally one-off studies that use proprietary commercial data or other physical or socio-economic data that are limited geographically. Open geospatial data are increasingly available for large areas; however, their unstructured nature has hindered their use in extracting useful insights to inform decision making. In this study, we demonstrate an approach to map deprived areas within and across cities using open-source geospatial data. The study tests this methodology in three African cities—Accra (Ghana), Lagos (Nigeria), and Nairobi (Kenya) using a three arc second spatial resolution. Using three machine learning classifiers, (i) models were trained and tested on individual cities to assess the scalability for large area application, (ii) city-to-city comparisons were made to assess how the models performed in new locations, and (iii) a generalized model to assess our ability to map across cities with training samples from each city was designed. Our best models achieved over 80% accuracy in all cities. The study demonstrates an inexpensive, scalable, and transferable approach to map deprived areas that outperforms existing large area methods.
在许多低收入和中等收入国家,关于贫民窟或贫困生活条件的可靠数据仍然很少。贫困地区的全球高分辨率地图是研究和循证政策的基础。现有的制图方法通常是一次性研究,使用专有的商业数据或其他地理上有限的物理或社会经济数据。开放的地理空间数据越来越多地用于大面积;然而,它们的非结构化性质阻碍了它们在提取有用的见解以通知决策方面的使用。在本研究中,我们展示了一种利用开源地理空间数据绘制城市内部和城市之间贫困地区地图的方法。该研究在三个非洲城市——阿克拉(加纳)、拉各斯(尼日利亚)和内罗毕(肯尼亚)——使用三弧秒的空间分辨率测试了这种方法。使用三个机器学习分类器,(i)在单个城市上对模型进行训练和测试,以评估大面积应用的可扩展性,(ii)对城市进行比较,以评估模型在新地点的表现,以及(iii)设计了一个广义模型,以评估我们使用来自每个城市的训练样本绘制城市地图的能力。我们最好的模型在所有城市的准确率都超过80%。该研究展示了一种廉价、可扩展和可转移的方法来绘制贫困地区的地图,优于现有的大面积方法。

As a primary goal, urban green spaces (UGSs) have been linked to several aspects of inhabitants’ wellbeing. Quality could be a way to intervene in the UGS–human health interaction. For that purpose, we developed an urban green space quality index (UGS QIndex) applied to a Mediterranean region, Sousse City. This index was based on a set of criteria, indicators, and elements chosen after bibliographical research related to UGS quality assessment tools and their contribution to the Sustainable Development Goals. Then, we evaluated the quality of the Sousse Ramparts Gardens using the UGS QIndex. In fact, this index includes 41 elements grouped into 23 indicators covering seven thematic criteria: environmental regulating capacity, functional amenities, aesthetic amenities, landscape features, integration in its surroundings, development policy objectives, and space issues. According to the UGS QIndex, Bab El Gharbi garden exceeds Bab El Finga garden in terms of its scenery, aesthetics, and functionality. This index could be used by city planners to improve their UGS’s capacity to satisfy the inhabitants’ requirements. Otherwise, it needs to be enhanced and tailored to various types of UGSs and then applied to other Mediterranean cities, as well as cities suffering from UGS degradation.
作为主要目标,城市绿色空间(UGSs)与居民福祉的几个方面有关。质量可能是干预ugs -人类健康相互作用的一种方式。为此,我们开发了一个应用于地中海地区苏塞市的城市绿地质量指数(UGS QIndex)。该指数基于与UGS质量评估工具及其对可持续发展目标的贡献相关的书目研究后选择的一套标准、指标和要素。然后,我们使用UGS QIndex对苏塞壁垒花园的质量进行了评价。事实上,该指数包括41个要素,分为23个指标,涵盖7个主题标准:环境调节能力、功能设施、审美设施、景观特征、与周围环境的融合、发展政策目标和空间问题。根据UGS QIndex, Bab El Gharbi花园在风景、美学和功能方面都超过了Bab El Finga花园。这个指数可以被城市规划者用来提高他们的UGS满足居民需求的能力。否则,就需要针对不同类型的地漏进行增强和定制,然后应用于其他地中海城市,以及遭受地漏退化的城市。

There are strong indications that the built environment has had a great influence on the course of the COVID-19 pandemic and the post-disaster recovery. The COVID-19 pandemic has adversely affected both human and global development, while efforts to combat this menace call for an integrated human social capital index. This research seeks to enhance understanding of how the built environment can be enhanced through resilience against the backdrop of the COVID-19 pandemic. This study aims to investigate the impact of a resilient built environment on increasing resilience in the aftermath of the COVID-19 pandemic in Nigeria. The quantitative studies test the impact of four built environment resilience indices (built environment capital, disaster management indices, awareness of the COVID-19 pandemic, and built environment adaptive strategies) on human social capital and COVID-19 pandemic indices. This study reveals the role of human social capital in achieving a resilient built environment in the wake of the COVID-19 pandemic in Nigeria. Built environment capital, disaster management indices, and awareness of COVID-19 also indirectly affect the COVID-19 pandemic indices through human social capital. This study’s implications are useful for post-COVID-19 recovery, which is important for future planning of the built environment in Nigeria.
有强烈迹象表明,建筑环境对COVID-19大流行的进程和灾后恢复产生了巨大影响。2019冠状病毒病大流行对人类和全球发展都产生了不利影响,为应对这一威胁,需要制定综合人力社会资本指数。本研究旨在加深对如何通过应对COVID-19大流行的韧性来改善建筑环境的理解。本研究旨在调查在尼日利亚2019冠状病毒病大流行后,弹性建筑环境对提高抵御能力的影响。定量研究检验了四项建筑环境弹性指数(建筑环境资本、灾害管理指数、COVID-19大流行意识和建筑环境适应策略)对人力社会资本和COVID-19大流行指数的影响。本研究揭示了在尼日利亚2019冠状病毒病大流行之后,人力社会资本在实现有复原力的建筑环境方面的作用。建筑环境资本、灾害管理指数和COVID-19意识也通过人力社会资本间接影响COVID-19大流行指数。这项研究的启示对2019冠状病毒病后的恢复很有用,这对尼日利亚未来的建筑环境规划很重要。

Urban mobility and strategies for public transportation play a vital role in promoting a more sustainable, accessible, and livable urban environment in smart cities. Data-driven decision making, multi-modal integration, and innovative means are key elements in developing effective public transportation. The COVID-19 pandemic had a significant impact on public transportation worldwide, including decreased travel, health and security concerns, and a shift in travel patterns. In particular, the use of public transportation reduced by up to 90% in developed countries. This article studies the mobility demands and patterns related to public transportation in Montevideo, Uruguay, amidst the COVID-19 pandemic. The study follows an urban data analysis approach, using open data from various sources, including citizen mobility, the public transportation system, COVID-19 case records, and economic indicators. The urban data methodology allows the deriving of significant findings, encompassing the assessment of trip reductions in Montevideo in March 2020 (71.4%, lower than similar cities in the world), the correlation between trip numbers and COVID-19 cases during the different pandemic waves, the recovery of public transportation usage, and the correlation with socio-economic indicators. These results offer valuable insights for quantifying and comprehending the behavior of citizens concerning public transportation throughout the COVID-19 pandemic, providing valuable understandings for policymakers and researchers to elaborate mobility strategies and policies.
在智慧城市中,城市交通和公共交通战略在促进更可持续、更便利和更宜居的城市环境中发挥着至关重要的作用。数据驱动的决策、多模式整合和创新手段是发展有效公共交通的关键要素。2019冠状病毒病大流行对全球公共交通产生了重大影响,包括旅行、健康和安全问题减少,以及旅行模式的转变。特别是在发达国家,公共交通的使用减少了高达90%。本文研究了COVID-19大流行期间乌拉圭蒙得维的亚公共交通的出行需求和模式。该研究采用城市数据分析方法,使用来自各种来源的开放数据,包括公民流动性、公共交通系统、COVID-19病例记录和经济指标。城市数据方法可以得出重要的发现,包括评估2020年3月蒙得维的亚的出行减少(71.4%,低于世界同类城市),不同大流行期间出行次数与COVID-19病例之间的相关性,公共交通使用的恢复以及与社会经济指标的相关性。这些结果为量化和理解2019冠状病毒病大流行期间公民在公共交通方面的行为提供了宝贵的见解,为政策制定者和研究人员制定交通战略和政策提供了宝贵的理解。

European regions with a lower population density have greater structural difficulties in ensuring that the daily life of their inhabitants matches that of more populated regions. This problem persists in groups of people who present some type of disability. Soria (Spain) is one of such regions. It is considered the most depopulated region of Southern Europe. Therefore, the aim of this study was to analyse the reality of people with disabilities in one of the provinces with a lower population density. It also seeks to explore the relationship between the perceptions and the reality of the existing structure to infer the promotions or limitations of agency. To this end, we conducted a systematic review of the existing literature, a sociogeographic study of the study context, and a mixed investigation. The results show that the greatest problem lies in the cities and towns located far away from the capital city, causing budget cutbacks and, therefore, reducing the attention to the needs of people with disabilities. However, social solidarity has increased, which is perceived as greater social inclusion for this group.
人口密度较低的欧洲区域在确保其居民的日常生活与人口较多的区域相匹配方面面临更大的结构性困难。这个问题在有某种残疾的人群中仍然存在。索里亚(西班牙)就是这样一个地区。它被认为是南欧人口最稀少的地区。因此,本研究的目的是分析一个人口密度较低的省份的残疾人现状。它还试图探索感知与现有结构的现实之间的关系,以推断机构的促进或限制。为此,我们对现有文献进行了系统回顾,对研究背景进行了社会地理研究,并进行了混合调查。结果表明,最大的问题在于远离首都的城镇,导致预算削减,从而减少了对残疾人需求的关注。然而,社会团结有所增加,这被认为是对这一群体更大的社会包容。

Amman, the capital of Jordan, has experienced significant traffic congestion due to the rise in private vehicle ownership and limited public transportation services. A Stated Preference (SP) survey was conducted to determine public transportation users’ willingness to use the Bus Rapid Transit (BRT) service. Another survey assessed the demand for an on-demand transit bus service with flexible and moderate costs, particularly for individuals far from the main BRT stations who need to reach them. Two models, Multinomial Logit (MNL) and Mixed Logit (ML), were utilized to understand user preferences for work-related trips. The study findings indicate that the cost of the trip and the waiting time are the two primary factors influencing public transport users’ choices. Furthermore, sociodemographic factors, such as age, income, household size, and current status, were found to have a significant impact. The results reveal that approximately 71% of participants would utilize an integrated public transportation system comprising BRT and on-demand services. The findings underscore the potential benefits of an integrated public transport system in addressing Amman’s traffic congestion. By combining BRT and on-demand services, the city can offer residents comfortable, affordable, and efficient transportation options, thus effectively mitigating congestion.
由于私家车拥有量的增加和公共交通服务的有限,约旦首都安曼经历了严重的交通拥堵。一项声明偏好(SP)调查是为了确定公共交通用户使用快速公交(BRT)服务的意愿。另一项调查评估了人们对灵活、成本适中的按需公交服务的需求,尤其是那些远离主要BRT站点、需要到达这些站点的人。两个模型,多项Logit (MNL)和混合Logit (ML),被用来了解用户对工作相关旅行的偏好。研究结果表明,出行成本和等待时间是影响公共交通用户选择的两个主要因素。此外,社会人口因素,如年龄、收入、家庭规模和现状,被发现有显著的影响。结果显示,约71%的参与者将使用由快速公交和按需服务组成的综合公共交通系统。调查结果强调了综合公共交通系统在解决安曼交通拥堵问题方面的潜在好处。通过结合BRT和按需服务,城市可以为居民提供舒适、负担得起和高效的交通选择,从而有效缓解拥堵。

Complicating ‘Suburbanization’ and Spatial Assimilation: The Complex Residential Patterns of Southeast Asian Americans in the Minneapolis-St. Paul Metropolitan Area from 1990 to 2010 复杂的“郊区化”与空间同化:明尼阿波利斯-圣路易斯市东南亚裔美国人的复杂居住模式。从1990年到2010年

Although spatial assimilation has often been defined as the process whereby a group attains residential propinquity with majority members of a host society, we argue that for certain immigrant groups, substantial suburbanization does not necessarily lead to racial integration. Our analysis using data from the U.S. Census Bureau reveals that between 1990 and 2010, Southeast Asian former refugees in the Minneapolis-St. Paul Metropolitan Statistical Area experienced substantial suburbanization, which is expected given their improved socioeconomic status. However, Southeast Asians’ suburbanization has not led to residential propinquity with non-Hispanic Whites. Despite a small decline in Southeast Asians’ overall segregation at the metropolitan area level during the previous two decades, their segregation levels, as measured by the dissimilarity index, remained unchanged or increased in the central city and the suburbs. Furthermore, our findings reveal different ethnic concentration and segregation patterns among four Southeast Asian subgroups, complicating the meaning of ‘suburbanization’ as simply a process in which people move from the inner city to its less urban outskirts. The finding that substantial suburbanization coexists with high levels of segregation and ethnic concentration raises questions about the assumptions of both the spatial assimilation and place stratification models of immigrant residential processes and outcomes.
虽然空间同化通常被定义为一个群体与东道国社会的大多数成员实现居住接近的过程,但我们认为,对于某些移民群体来说,实质性的郊区化并不一定会导致种族融合。我们利用美国人口普查局的数据进行的分析显示,1990年至2010年间,明尼阿波利斯-圣路易斯市的东南亚前难民。保罗大都会统计区经历了大量的郊区化,鉴于其社会经济地位的提高,这是可以预料的。然而,东南亚人的郊区化并没有导致他们与非西班牙裔白人居住在一起。尽管在过去的二十年里,东南亚人在大都市区的整体隔离程度略有下降,但以差异指数衡量,他们在中心城市和郊区的隔离程度保持不变或有所增加。此外,我们的研究结果揭示了四个东南亚亚群体之间不同的种族集中和隔离模式,使“郊区化”的含义复杂化,即人们从内城迁移到城市郊区的简单过程。大量郊区化与高度隔离和种族集中共存的发现,对移民居住过程和结果的空间同化和地方分层模型的假设提出了质疑。

The finding that substantial suburbanization coexists with high levels of segregation and ethnic concentration raises questions about the assumptions of both the spatial assimilation and place stratification models of immigrant residential processes and outcomes.","PeriodicalId":75284,"journal":{"name":"Urban science (Basel, Switzerland)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135730664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Environmental, social, and governance issues have gained significant prominence recently, particularly with a growing emphasis on environmental protection. In the realm of heightened environmental concerns, unmanned aerial vehicles have emerged as pivotal assets in addressing transportation challenges with a sustainable perspective. This study focuses on enhancing unmanned aerial vehicles’ object detection proficiency within the realm of sustainable transportation. The proposed method refines the YOLOv7 E-ELAN model, tailored explicitly for traffic scenarios. Leveraging strides in deep learning and computer vision, the adapted model demonstrates enhancements in mean average precision, outperforming the original on the VisDrone2019 dataset. This approach, encompassing model component enhancements and refined loss functions, establishes an efficacious strategy for precise unmanned aerial vehicles object detection. This endeavor aligns seamlessly with environmental, social, and governance principles. Moreover, it contributes to the 11th Sustainable Development Goal by fostering secure urban spaces. As unmanned aerial vehicles have become integral to public safety and surveillance, enhancing detection algorithms cultivates safer environments for residents. Sustainable transport encompasses curbing traffic congestion and optimizing transportation systems, where unmanned aerial vehicle-based detection plays a pivotal role in managing traffic flow, thereby supporting extended Sustainable Development Goal 11 objectives. The efficient utilization of unmanned aerial vehicles in public transit significantly aids in reducing carbon footprints, corresponding to the “Environmental Sustainability” facet of Environmental, Social, and Governance principles.
环境、社会和治理问题最近得到了显著的突出,特别是随着对环境保护的日益重视。在环境问题日益严重的情况下,无人机已经成为解决可持续交通挑战的关键资产。本研究的重点是在可持续交通领域中提高无人机的目标检测能力。该方法对YOLOv7 E-ELAN模型进行了细化,明确针对交通场景进行了定制。利用深度学习和计算机视觉方面的进步,调整后的模型在平均精度上有所提高,在VisDrone2019数据集上优于原始模型。该方法包括模型组件增强和改进的损失函数,为精确的无人机目标检测建立了有效的策略。这一努力与环境、社会和治理原则无缝结合。此外,它还通过营造安全的城市空间,为实现第11项可持续发展目标作出贡献。随着无人驾驶飞行器成为公共安全和监视不可或缺的一部分,增强检测算法可以为居民创造更安全的环境。可持续交通包括遏制交通拥堵和优化交通系统,其中基于无人机的检测在管理交通流量方面发挥着关键作用,从而支持可持续发展目标11的扩展目标。在公共交通中有效利用无人机有助于减少碳足迹,符合环境、社会和治理原则的“环境可持续性”方面。

Urban Renewals: Learning from a Country’s Recent Experience for Enhancing Socially-Sustainable Global Planning Policy 城市更新:借鉴一国近期经验,加强社会可持续发展的全球规划政策

Against the background of urban redevelopment programs through the lens of varied, country-related planning cultures, this article sets the stage for learning from one country’s recent experience. In this article, we focus on two Israeli urban regeneration programs operating since 2000: the ‘Integrated National Planning Scheme’ (TAMA 38) and ‘Evacuate and Build’ (Pinuy Binuy) programs. This article aims to examine the governmental agenda behind these programs in comparison to previous urban regeneration programs and, especially, to critically review the implementation and implication of these programs considering social sustainability issues. Methodologically, the policies and practices of this recent wave of urban renewals in Israel are revisited through a critical reading of a series of studies from the last five years, bringing together multidimensional societal aspects. In terms of ethics and qualitative dimensions, the examined societal aspects are rooted in social sustainability theory and contemporary urban policy design. Our findings regarding this country-related recent experience in urban renewals have identified several gaps concerning certain aspects of social sustainability theory and practice. These gaps call for a better understanding by Israel’s urban policy makers of the comprehensive essence of contemporary social sustainability theory, which should also be mirrored in the respective professional discourse. The gaps are also useful in informing our accumulating transnational knowledge and experience in urban renewal schemes, based on a chain of country-related experiences and planning cultures.
在城市改造项目的背景下,通过不同国家相关的规划文化,本文为学习一个国家最近的经验奠定了基础。在本文中,我们将重点介绍以色列自2000年以来实施的两个城市更新项目:“综合国家规划方案”(TAMA 38)和“疏散与建设”(Pinuy Binuy)项目。本文旨在研究这些项目背后的政府议程,并与以往的城市更新项目进行比较,特别是在考虑到社会可持续性问题的情况下,批判性地审查这些项目的实施和影响。在方法上,通过对过去五年的一系列研究的批判性阅读,重新审视了以色列最近一波城市更新的政策和实践,汇集了多方面的社会方面。在伦理和定性方面,研究的社会方面根植于社会可持续性理论和当代城市政策设计。我们关于这个国家在城市更新方面的最新经验的研究发现,在社会可持续性理论和实践的某些方面存在一些差距。这些差距要求以色列的城市决策者更好地理解当代社会可持续性理论的综合本质,这也应该反映在各自的专业话语中。这些差距也有助于我们根据一系列与国家有关的经验和规划文化,在城市更新计划方面积累跨国知识和经验。
