Abstract The paper analyzes crisis situations solved by The Fire Rescue Service of the South Moravian Region (FRS) in the city of Brno during 24 weeks between 7th April 2013 and 20th September 2013. The article deals briefly with all FRS actions and then focuses on fires. The open-access database of FRS is used for analysis. It is accessed from a database of the innovative web application StreetAlert, which allows users to learn about current fire brigade actions in the specified distance from the mobile phone. The data are processed in PostgreSQL and then spatial analysis is performed using the most detailed administrative division of the city – basic settlement units. As this division of urban space is used also in the most recent Czech census (2011), it is possible to use sociodemographic statistical data for comparison. The article identifies spatial regularities in the distribution of fires, describes the structure of the fires in terms of the type of event (fires of waste, fires of grass and forest, fires of buildings), discovers their possible dependence on the specific characteristics of urban space, finds potentially dangerous places (kernel density analysis), draws valid conclusions applicable to similar settlements, and shows the possible use of the data for local government. The main benefit of the research lies in revealing the spatial distribution of the examined phenomena.

Mental health–related calls for service are increasing across Canadian communities. However, the spatial dynamics of these calls for service and their potential relationship with concentrations of crime has not been fully investigated in the Canadian context. The current study examines mental health and other calls for service in a medium-sized (approximate population of 250,000), midwestern Canadian city in the year 2014. Using kernel density analysis and a spatial point pattern test, the study explores the concentration and spatial patterns of mental health calls for service across the city. Findings indicate that mental health calls for service differ from other crime-related calls for service, except for violent crime. Possible explanations for this pattern and considerations for policy and policing are discussed.

Drawing on field research and a survey of 150 Zimbabwean migrants in Johannesburg, this paper explores the dimensions of migrants’ transnational experiences in the urban space. I discuss the use of communication platforms such as WhatsApp and Facebook as well as other means such as telephone calls in fostering the embedding of transnational migrants within both the Johannesburg and the Zimbabwean socio-economic environments. I engage this migrant-embedding using Bourdieusian concepts of “transnational habitus” and “transnational social field,” which are migration specific variations of Bourdieu’s original concepts of “habitus” and “social field.” In deploying these Bourdieusian conceptual tools, I observe that the dynamics of South–South migration as observed in the Zimbabwean migrants are different to those in the South–North migration streams and it is important to move away from using the same lens in interpreting different realities. For Johannesburg-based migrants to operate within the socio-economic networks produced in South Africa and in Zimbabwe, they need to actively acquire a transnational habitus. I argue that migrants’ cultivation of networks in Johannesburg is instrumental, purposive, and geared towards achieving specific and immediate goals, and latently leads to the development and sustenance of flexible forms of permanency in the transnational urban space.

The subject of the article is an analysis of the three aspects of depicting urban space of Eastern Ukraine, focusing specifi cally on the Donbass region and the city of Kharkov as depicted in the novels Voroshilovgrad (2010) and Mesopotamia (2014) by Serhiy Zhadan. The urban space of Eastern Ukraine overlaps with the most important values that shape a person’s personality and aff ect her or his self-identifi cation. The city space is also a “place of memory” and experiences of generations that infl uence current events. In addition to the historical and axiological dimension, the imaginative aspect of space is also important. This approach is used by the author to describe the urban space as a functioning imagination or stereotypes associated with it as opposed to its realistic depiction.

O objetivo que permeia a presente pesquisa é utilizar a Fortaleza de Santa Cruz, localizada no bairro de Jurujuba, em Niterói, construída em 1555, na entrada da barra da Baía de Guanabara, como foco de antílise, ressaltando a importância deste fixo social enquanto atração turística e de lazer, incluindo a cidade de Niterói no circuito destas atividades, complementares à cidade do Rio de Janeiro; além de abordar conceitos e categorias analíticas, oriundos das ciências sociais, principalmente provenientes da Geografia, pertinentes ao estudo das atividades em tela. Neste contexto, na dinâmica espacial da cidade de Niterói, o processo de mudança de função dos fixos sociais têm sido extraordinário. Residencias unifamiliares, prédios e até mesmo fortificações militares, verdadeiras monumentalidades, foram refuncionalizadas, passando por um processo de turistificação. Assim, a refuncionalização da respectiva Fortaleza em espaço cultural toma-se um importante atrativo da história, do patrimônio, da cultura, marcando no espaço urbano sua expressões e monumentalidade, criada pelo homem como símbolo de seus ideais, objetivos e atos, constituindo-se em um legado as gerações futuras, formando um elo entre passado, presente e futuro. Abstract This paper focuses on Santa Cruz Fortress, built in 1555 in Jurujuba (Niterói), to guard the entrance of Guanabara bay, and stresses its role as a towist attraction and leisure' area, as a social fix which links the city of Niterói to the complementary circuit of these activities in the city of Rio de Janeiro. The study uses important concepts and analytic categories fiom social sciences, particularly fiom Geography.In the spatial dynamic of the city of Niterói, change in functions of social fuces has been extraordinary. Single-family dwellings, buildings and even military installations have been re-functionalized, undergoing a process of touristification. In that way, the refunctionalization of the Fortress as a cultural space provides an important attraction in the domains of history, patrimony, and culture, providing the urban space with an expression of monumentality, created by man as a symbol of his ideals, aims and actions, a legacy to future generations forming a link between past, present and future.

Cities or municipalities are often the most immediate institutional facilitators of global justice. Thus, it is important for cosmopolitans and other theorists interested in global justice to consider the importance of the correspondence between global theories and local actions. In this chapter, the authors explore the role that municipalities can play in interpreting and executing principles of global justice. They offer a way of thinking about the cosmopolitan or global city not as a gentrified and commodified urban space, but as a site of local governance consistent with egalitarian cosmopolitan moral aims. They work to show some ways in which the city of Medellín, Colombia, has taken significant steps in that direction. The chapter focuses especially on how it did so and how it might serve as a model in some important ways for the transformation of other cities globally in a direction more consistent with egalitarian cosmopolitanism.

This book analyses the physical, social, and cultural history of Rome in late antiquity. Between AD 270 and 535, the former capital of the Roman empire experienced a series of dramatic transformations in its size, appearance, political standing, and identity, as emperors moved to other cities and the Christian church slowly became its dominating institution. Urban Space and Aristocratic Power in Late Antique Rome provides a new picture of these developments, focusing on the extraordinary role played by members of the traditional elite, the senatorial aristocracy, in the redefinition of the city, its institutions, and spaces. During this period, Roman senators and their families became increasingly involved in the management of the city and its population, in building works, and in the performance of secular and religious ceremonies and rituals. As this study shows, for approximately three hundred years the houses of the Roman elite competed with imperial palaces and churches in shaping the political map and the social life of the city. Making use of modern theories of urban space, the book considers a vast array of archaeological, literary, and epigraphic documents to show how the former centre of the Mediterranean world was progressively redefined and controlled by its own elite.

AbstractThis collaborative and comparative paper deals with the impact of Covid-19 on the use and governance of public space and street trade in particular in two major African cities. The importance of street trading for urban food security and urban-based livelihoods is beyond dispute. Trading on the streets does, however, not occur in neutral or abstract spaces, but rather in lived-in and contested spaces, governed by what is referred to as ‘street geographies’, evoking outbreaks of violence and repression. Vendors are subjected to the politics of municipalities and the state to modernize the socio-spatial ordering of the city and the urban food economy through restructuring, regulating, and restricting street vending. Street vendors are harassed, streets are swept clean, and hygiene standards imposed. We argue here that the everyday struggle for the street has intensified since and during the Covid-19 pandemic. Mobility and the use of urban space either being restricted by the city-state or being defended and opened up by street traders, is common to the situation in Harare and Kisumu. Covid-19, we pose, redefines, and creates ‘new’ street geographies. These geographies pivot on agency and creativity employed by street trade actors while navigating the lockdown measures imposed by state actors. Traders navigate the space or room for manoeuvre they create for themselves, but this space unfolds only temporarily, opens for a few only and closes for most of the street traders who become more uncertain and vulnerable than ever before, irrespective of whether they are licensed, paying rents for vending stalls to the city, or ‘illegally’ vending on the street.

Having in mind the objectives of the United Nations Development Agenda 2030, which refers to the sustainable principles of a circular economy, it is urgent to improve the performance of the built environment. The existing buildings must be preserved and improved in order to reduce their environmental impact, in line with the need to revert climate change and reduce the occurrence of natural disasters. This work had as its main goal to identify and define a methodology for promoting the rehabilitation of buildings in the Ponte Gêa neighborhood, in the city of Beira, Mozambique, with an emphasis on energy efficiency, water efficiency, and construction and demolition waste management. The proposed methodology aims to create a decision support method for creating strategic measures to be implemented by considering the three specific domains—energy, water, and waste. This model allows for analyzing the expected improvement according to the action to be performed, exploring both individual and community solutions. It encompasses systems of standard supply that can reveal greater efficiency and profitability. Thus, the in-depth knowledge of the characteristics of urban space and buildings allows for establishing guidelines for the renovation process of the neighborhood.

AbstractTo determine the risk state distribution, risk level, and risk evolution situation of agricultural non-point source pollution (AGNPS), we built an ‘Input-Translate-Output’ three-dimensional evaluation (ITO3dE) model that involved 12 factors under the support of GIS and analyzed the spatiotemporal evolution characteristics of AGNPS risks from 2005 to 2015 in Chongqing by using GIS space matrix, kernel density analysis, and Getis-Ord Gi* analysis. Land use changes during the 10 years had a certain influence on the AGNPS risk. The risk values in 2005, 2010, and 2015 were in the ranges of 0.40–2.28, 0.41–2.57, and 0.41–2.28, respectively, with the main distribution regions being the western regions of Chongqing (Dazu, Jiangjin, etc.) and other counties such as Dianjiang, Liangping, Kaizhou, Wanzhou, and Zhongxian. The spatiotemporal transition matrix could well exhibit the risk transition situation, and the risks generally showed no changes over time. The proportions of ‘no-risk no-change’, ‘low-risk no-change’, and ‘medium-risk no-change’ were 10.86%, 33.42%, and 17.25%, respectively, accounting for 61.53% of the coverage area of Chongqing. The proportions of risk increase, risk decline, and risk fluctuation were 13.45%, 17.66%, and 7.36%, respectively. Kernel density analysis was suitable to explore high-risk gathering areas. The peak values of kernel density in the three periods were around 1110, suggesting that the maximum gathering degree of medium-risk pattern spots basically showed no changes, but the spatial positions of high-risk gathering areas somehow changed. Getis-Ord Gi* analysis was suitable to explore the relationships between hot and cold spots. Counties with high pollution risks were Yongchuan, Shapingba, Dianjiang, Liangping, northwestern Fengdu, and Zhongxian, while counties with low risks were Chengkou, Wuxi, Wushan, Pengshui, and Rongchang. High-value hot spot zones gradually dominated in the northeast of Chongqing, while low-value cold spot zones gradually dominated in the Midwest. Our results provide a scientific base for the development of strategies to prevent and control AGNPS in Chongqing.

ABSTRACTThe traditional open-air markets on the central squares of Danish cities were thriving in the middle of the nineteenth century. However, the markets were soon challenged by new urban ideals of the city centre as a place for shopping and capital investment. At the same time, urban reformers made efforts to improve the market trade to meet modern standards. The rivalling interests struggled over the question of modernization or relocation of the central square markets and ultimately the definition and use of the central urban space. In particular, this article will examine the struggle over the construction of a fish market hall in Odense as it serves to reveal the different conceptions of the central urban space that affected the fate of the street markets.
