Abstract Academic production about the main Chilean cities exceeds the existing documentation on intermediate cities, though they have shown interesting trends patterns in recent years which have changed the urban system in Chile. This paper aimed to analyze the urban growth processes in Chilean intermediate cities using Temuco as a case study. It begins with an historical look at the city and then mentions that in the last decades this kind of cities have undergone new forms of segregation associated to real estate activities such as private communities, rural residential properties and new localization of services which have resulted in a fragmentation of urban space, a phenomenon reinforced by the consolidation of some satellite cities. At the same time, many urban problems associated to poverty, like a standstill of the regional economy and environmental pollution have appeared, jeopardizing the sustainability of these spaces, questioning current development parameters. The article ends considering the future challenges in Temuco’s urban development.

Due to irregular and uncontrolled expansion of cities in developing countries, currently operational landfill sites cannot be used in the long-term, as people will be living in proximity to these sites and be exposed to unhygienic circumstances. Hence, this study aims at proposing an integrated approach for determining suitable locations for landfills while considering their physical expansion. The proposed approach utilizes the fuzzy analytical hierarchy process (FAHP) to weigh the sets of identified landfill location criteria. Furthermore, the weighted linear combination (WLC) approach was applied for the elicitation of the proper primary locations. Finally, the support vector machine (SVM) and cellular automation-based Markov chain method were used to predict urban growth. To demonstrate the applicability of the developed approach, it was applied to a case study, namely the city of Mashhad in Iran, where suitable sites for landfills were identified considering the urban growth in different geographical directions for this city by 2048. The proposed approach could be of use for policymakers, urban planners, and other decision-makers to minimize uncertainty arising from long-term resource allocation.

Abstract Today, Algeria is one of the developing countries that are engaging seriously into a new approach consisting of all kinds of combined risk assessments for better prevention them. Note that, this is a fairly important parameter, that is, the safety of people and property. However, the magnitude of the risk, of whatever nature, affects a variety of diversified aspects (Human, economic, technical and environmental). This study presented a case study, which is sometimes paradoxical, seeing that it is the result of the combination of all risk factors and specific factors related to them connected to a fragile urban environment: Hassi-Messaoud. It is well known that Hassi-Messaoud is one of the most important city for Algeria's economy; in which the demographic development is mainly known by incessant flows of immigrants, motivated essentially by job search. This arbitrary of population distribution exposes this city to a certain danger; especially as Hassi-Messaoud is in a zone subject to a probable risk expressed here by being characteristic of an oil zone. Thus, this article aimed to provide elements of risk assessment related to oil activity. This approach could conclude that, through a schematic scale, the different types and levels of exposure and vulnerability could be identified, that is, characteristics of the urban space in question.

Urban geology is a preliminary study for the construction and development of cities, which has been more prominent in recent decades in some countries despite its long application history. It assesses the impact of geological and natural phenomena on urban space and available structures. The earthquake on Nov. 21, 2017, inflicted a lot of damage to the city of Sarpol-e Zahab, west of Iran, including financial losses and casualties. Reconstruction of this city and planning for its sustainable development entail conducting urban geological studies. In the present study, the effect of natural phenomena on Sarpol-e Zahab County was studied by investigating its geology and geomorphology. The results showed that, in addition to the earthquake that habitually affected the city of Sarpol-e Zahab, the hazards of other phenomena are also significant. Recorded horizontal acceleration in the recent earthquake confirmed the high seismicity of Sarpol-e Zahab has.

The purpose of this study was to analyze guerrilla gardening’s relationship to urban space and contemporary notions of sustainability. To achieve this two case studies of urban agriculture, one of guerrilla gardening and one of community gardening were developed. Through this comparison, guerrilla gardening was framed as a method of spatial intervention, drawing in notions of spatial justice and the right to the city as initially theorized by Henri Lefebvre. The guerrilla gardening case study focuses on Dig Kingston, a project started by the researcher in June of 2010, and the community gardening case study will use the Oak Street Garden, the longest standing community garden in Kingston. The community gardening case study used content analysis and semi-structured long format interviews with relevant actors. The guerrilla gardening case study consisted primarily of action based research as well as content analysis and semi-structured long format interviews. By contributing to the small, but growing, number of accounts and research on guerrilla gardening this study can be used as a starting point to look into other forms of spatial intervention and how they relate to urban space and social relations. Furthermore, through the discussion of guerrilla gardening in an academic manner more legitimacy and weight will be given to it as a method of urban agriculture and interventionist tactic. On a wider scale, perhaps it could even contribute to answering the question of how we (as a society) can transform our cities and reengage in urban space.

This paper presents an English case of urban agriculture, the Edible Public Space Project in Leeds, contextualised in a context of urban agriculture initiatives committed to social-environmental justice, to the reproduction of common goods and the promotion of an urban planning which promotes the right to food and to the construction of urban space from the bottom up. The case study emerged as the result of action-research at the crossroads between urban planning policies, community work and critical geography. As opposed to many similar initiatives, the Edible Public Space Project is not intended merely as a temporary initiative hidden within the tiny folds of the city, but rather as an experiment which imagines and implements alternatives to current forms of urban planning within those folds and it contextualises them in the light of the ecological, fi nancial and social crisis of the last decade.

This article will unfold a longe durée spatial biography of the urban area of Bixiga (São Paulo, Brazil) to probe the particular role of space in the conflation of different cultural practices and territorial claims. The extended case study bridges indigenous, colonial, and postcolonial urbanization as they amalgamated an intricate assemblage of material and cultural strata. Combined historical urban analysis and fieldwork allow to uncover how the resulting urban milieu integrates discrepant urban worlds, perpetually iterating between centrality and marginality, innovation and degradation, oppression and resistance. Building on Foucault’s (1984) conception of heterotopia, Bixiga will surface as an allotopia, a place that accommodates, cumulates, and celebrates a multitude of differences. It sheds light, this way, on more insurgent histories of urbanism, where urban space is piecemeal forged through contentious struggles over space in the city.

This article proposes a methodology to address the urban evolutionary process, demonstrating how it is reflected in literature. It focuses on “literary space,” presented as a territory defined by the period setting or as evoked by the characters, which can be georeferenced and drawn on a map. It identifies the different locations of literary space in relation to urban development and the economic, political, and social context of the city. We suggest a new approach for mapping a relatively comprehensive body of literature by combining literary criticism, urban history, and geographic information systems (GIS). The home-range concept, used in animal ecology, has been adapted to reveal the size and location of literary space. This interdisciplinary methodology is applied in a case study to nineteenth- and twentieth-century novels involving the city of Lisbon. The developing concepts of cumulative literary space and common literary space introduce size calculations in addition to location and structure, previously developed by other researchers. Sequential and overlapping analyses of literary space throughout time have the advantage of presenting comparable and repeatable results for other researchers using a different body of literary works or studying another city. Results show how city changes shaped perceptions of the urban space as it was lived and experienced. A small core area, correspondent to a part of the city center, persists as literary space in all the novels analyzed. Furthermore, the literary space does not match the urban evolution. There is a time lag for embedding new urbanized areas in the imagined literary scenario.

Populations in contemporary cities are being measured, analyzed, or represented in less than optimal ways. Conventional methods of measuring density of populations in cities rely on calculating the number of people living within a bounded surface space. This approach fails to account for the multiple floor residential patterns of the contemporary urban landscape and exposes the vertical space problem in population analytics. To create an accurate representation of people in contemporary urban spaces, a move beyond the conventional conception of density is needed. This research aims to find a more appropriate solution to mapping humans in cities by employing a dasymetric method to represent the distribution of people in a city of vertical residential structures. The methodology creates an index to classify the amount of floor space for each person across the extent of the city, a metric called the personal space measure. The personal space measure is juxtaposed with the conventional population density measurements to provide a unique perspective on how population is concentrated across the urban space. The personal space metric demonstrates how improved metrics can be employed to better understand the social and structural landscape of cities. Chicago, with a large population and a high vertical extent, makes an ideal case study to develop a methodology to capture the phenomena of urban living in the 21st century and to explain alternative approaches to accurately and intelligently analyze the contemporary urban space.

The urban area consists of systems and sub-systems that have relationships with each other like a network. The development and changes in urban space are believed to influence the relationship between systems and also the meaning of all elements forming the urban spatial area. This also happens to the primary elements which are signs for the urban area. Given the changes in the city area, the existence of the primary elements as signs of a city area needs to be explored. The study is carried out on the primary elements in the city area which has a relatively complete city function. The case study is the European region in the center of Medan city, the capital of North Sumatra Province, Indonesia. This is a descriptive-analytical and interpretative-qualitative research. It aims to reveal all relationships that are intertwined in the function, form and meaning of the primary elements. The results of the study concluded that changes in primary elements as signs of the region shifted from symbolic meaning to pragmatic meaning.
