This paper investigates a moment of shift in urban neoliberal governance strategies under the purview of a new municipal Chief of Government of Buenos Aires at the end of the 2000s: the introduction of a regime of public space that has had implications for the waste management sector (and particularly informal recyclers or cartoneros). I document government attempts to re-represent the city as a modern, hygienic centre that is receptive to investment and tourism, drawing on discursive framings of public space that seek to redefine legitimate users and uses of the city. Such framings are exclusionary of cartoneros and other marginalized urbanites. As with most forms of actually existing neoliberalism, this regime is contradictory and unstable, both containing and provoking challenges to its coherence. This case study of ‘actually existing neoliberalism’ in Buenos Aires encourages analytical focus on moments of shift and renewal in urban processes of neoliberalization. In this case the shift marked by the introduction of the regime of public space reveals the priorities and agendas of urban elites as championed by municipal governments, makes visible the paradoxes and contradictions inherent to neoliberal urbanisms, and also exposes openings for resistance, opposition, and renegotiation of urban neoliberal agendas (including protest, discursive reframings of the city and its uses, and the forging of indeterminate alliances).

The notion of a hidden city of social reproduction, suggests that the uneven relations and material practices of social reproduction are respectively hidden and targeted by a neo-liberal urban agenda. A discussion of the public-private Grand Central Partnership in New York City, reveals some of the ways that this agenda is pursued through preservation, and addresses how particular social actors and their activities are removed from view in the interests of ensuring "orderly," "clean," and "safe" public space.

This is a study of Istanbul's periodic bazaars and an attempt to place them in the context of contestation over urban space, urban poverty and informality. The periodic bazaars in the city are either disappearing or being moved to the outskirts. These trends reflect and reproduce spatial unevenness in the city, manifesting new forms of social exclusion and polarization. The city's increasingly commodified urban space has become an arena of social and economic contestation. We address these questions by focusing on the story of the relocation of one of Istanbul's most popular periodic bazaars, the Tuesday bazaar in Kadıköy. Our analysis reveals that the relocation and reorganization of bazaars in Istanbul in the 2000s have largely been driven by rising real‐estate prices in the city: land has simply become too precious a commodity to be left to the bazaaris. Furthermore, in the context of a pervasive neoliberal discourse on urban renewal and modernization that promotes the notion of a hygienic city, the bazaaris, it seems, have become the new undesirables of the urban landscape, leaving them under double siege from the commodification of public land and from spatially defined social exclusion.

This article examines the new phenomenon of “citizens’ groups” in contemporary Mumbai, India, whose activities are directed at making the city’s public spaces more orderly. Recent scholarship on Mumbai’s efforts to become a “global” city has pointed to the removal of poor populations as an instance of neoliberal governmentality as espoused by the Indian state following the “liberalization” of the economy in the early 1990s. However, in this case, it is these civil society organizations, not the state—whose functionaries in fact benefit from a certain element of unruliness on the streets—who are the agents of increased control over populations and of the rationalization of urban space. This article, based on fieldwork-based research, argues that the way in which citizens’ groups exclude poor populations from the city is more complex than a straightforward deployment of neoliberalism, and is imbricated with transnational political economic arrangements in uneven and often inconsistent ways. In particular, this article explores how civic activists in these organizations envision their role in the city, and how their activism attempts to reconfigure the nature of citizenship. For instance, civic activists consider themselves to be the stewards of the city’s streets and sidewalks, and wage their battles against what they consider unruly hawkers, a corrupt state, and a complacent middle-class public. Moreover, civic activists render street hawkers’ political claims illegitimate by speaking on behalf of the abstract “citizen” of Mumbai, thus implying that hawkers’ unions speak only on behalf of the vested interests of a single population. In this way, they mobilize a normative notion of civil society in order to exclude the vast segment of city residents who either sell or buy goods on the street. In doing so, the civic activists transform the discourse and practice of politics in the city, so that, ironically, while on one hand using the rhetoric of citizen participation, they in fact undermine the radically heterogeneous forms of democratic political participation the city offers.

Latin American scholars have recently discussed the privatization of urban public space. A fundamental aspect of this process is the disintegration of communities because it often targets and affects a peculiarly Latin American kind of public space: the plaza. Plazas have traditionally functioned as cultural centres in Latin American cites. They are central meeting points for political groups, sites of civic expression and public resistance, as well as places to purchase relatively cheap goods and services. Plazas are, therefore, sites in which families, neighbours, and political organizations mingle, interact, and also challenge authority. This paper uses these sorts of insights on public space in Latin America to develop a conceptualization of the plaza as a community centre. However, the multiple practices and interactions that occur in these forms of public space have been disrupted by state-led strategies which seek to privatize and sanitize public space, thereby disrupting—or even destroying—the community centre. I use primary materials on Mexico City's Historic centre and its plaza to explore the ways in which this specific type of urban public space has been affected physically and symbolically by a regeneration scheme known as the Programa de Rescate.

This paper presents a comparative case study of two northern suburbs in Melbourne, Australia, in order to analyze local perceptions of proximity, mobility, and spaces of community interaction within diverse neighborhoods experiencing socioeconomic and demographic transition. We first look at government policies concerning the two suburbs, which position one suburb within a narrative of gentrification and the other within a narrative of marginalization. We then draw on diverse residents’ experiences and perceptions of local space, finding that these “everyday geographies” operate independently of and often at odds with local policy narratives of demographic and socioeconomic transition. We conclude that residents’ “everyday geographies” reveal highly varied and contested experiences of sociospatial dimensions of local change, in contrast to policy narratives that are often neoliberally framed.

Jane Jacobs's The Death and Life of Great American Cities (1961) had an enormous influence on urban design theories and practices. This study aims to operationalize Jacobs's conditions for a vital urban life. These are (1) mixed use, (2) small blocks, (3) aged buildings, and (4) a sufficient concentration of buildings. Jacobs suggested that a vital urban life could be sustained by an urban realm that promotes pedestrian activity for various purposes at various times. Employing multilevel binomial models, we empirically verified that Jacobs's conditions for urban diversity play a significant role with regard to pedestrian activity.

The way urban solids relate to urban voids, the spatial relations of urban space itself and all other characteristics that define urban space are paramount in determining human distribution in any given community. This determines social relations that in turn reproduce spatial relations. This kind of process determines what sort of community and hence environment that is eventually generated. It is the intention of this paper to establish urban variables and hence urban patterns that promote human distribution, which in turn creates a sustainable community. A further intention is to establish a language that could be used to generate policies and design rules for such communities.

The general aim of this paper is to demonstrate the significance of intentional soundscape design in urban squares by investigating people’s general perceptions of urban soundscape and sound preferences, and the effects of demographic factors. An intensive questionnaire survey was carried out in two urban squares in Sheffield. Sound identification and classification were both considered. The results show that natural sounds as a group were generally preferred to urban sounds; the preferences of soundscape elements influenced people’s choice of using an urban square; and in terms of sound preference, the differences amongst age groups were rather significant, whereas between males and females only slight differences were found. Finally, some suggestions on soundscape design in urban squares are given.

This paper proposes an essentially new theory of urban space based on information theory and the laws of optics. The use of urban space is linked to the information field generated by surrounding surfaces, and on how easily the information can be received by pedestrians. Historical building exteriors usually present a piecewise concave, fractal aspect, which optimizes visual and acoustical signals that transmit information content. Successful urban spaces also offer tactile information from local structures meant for standing and sitting. The total information field in turn determines the optimal positioning of pedestrian paths and nodes. This complex interaction between human beings and the built environment, incredibly neglected in our times, explains why so many historical urban spaces provide an emotionally nourishing environment.

This paper develops an analytical framework to place the rise of open source urbanism in context, and develops the concept of the ‘right to infrastructure’ as expressive of new ecologies of urban relations that have come into being. It describes, first, a genealogy for open source technology, focusing in particular on how open source urban hardware projects may challenge urban theory. It moves then to describe in detail various dimensions and implications of an open source infrastructural project in Madrid. In all, the paper analyses three challenges that the development of open source urban infrastructures is posing to the institutions of urban governance and property: the evolving shape and composition of urban ecologies; the technical and design challenges brought about by open source urban projects; and the social organisation of the ‘right to infrastructure’ as a political, active voice in urban governance. In the last instance, the right to infrastructure, I shall argue, signals the rise of the ‘prototype’ as an emerging figure for contemporary sociotechnical designs in and for social theory.

Existing urban open space typologies within dense urban fabrics cannot meet society’s open space requirements in developing countries’ metropolitan cities, such as Istanbul. Because of high building densities, it is a challenging task to create new open spaces within urban cores. Developing new tools that work with the existing built environment is crucial to reveal ‘opportunity spaces’ that can act as breathing points within dense urban fabrics. In this research, a new model is developed to evaluate the 3D spatial enclosure of open spaces using basic geometrical properties and geographic information system (GIS) tools. As a case study, Istanbul’s changing spatial organization is analyzed using this model.

How might the urban structure and public space of Christchurch change as a result of the 2010 and 2011 earthquakes? This paper will look at council and community led post-earthquake urban space projects in Christchurch, New Zealand, to investigate the potential reconfiguration of urban public space and structure and the balance of top-down and bottom-up design processes for the delivery of these projects. This will be achieved by comparing the performance of the urban public space and structure of the city during the post-earthquake emergency and recovery phases, with a view to understanding the contribution that these elements can make to the resilience of Christchurch. The paper will argue that Christchurch’s nineteenth century urban structure served the population well during the emergency phases of the disaster and that post-earthquake community-led initiatives model innovative capabilities which may enhance urban design practice in the future.

The study engages with the ways in which gender mix plays out in public spaces as a key issue in exploring social diversity and vitality of the urban public life. The paper introduces a mapping method to unravel how gender differences are spatially manifested in urban public spaces. Thus, urban mapping has been considered as a method for producing a kind of spatial knowledge that has the capacity to shed light on how different socio-spatial patterns play out in public open spaces. The proposed mapping method documents where and the extent to which female and male users appropriate urban public spaces. The database for developing and testing the proposed method emerges from two site areas in the city of Tehran. In doing so, the study draws upon direct observation, fieldwork notes, visual recording, and urban mapping as research methods. In this way, the paper raises questions about the importance of gender mix in public space and the ways in which mapping has the capacity to inform urban research.

This paper examines intermediate, semi-enclosed urban spaces and investigates the potential creation of environmental diversity when such spaces are integrated in urban design. More specifically, it focuses on the links between architectural characteristics of semi-enclosed spaces and their thermal performance. The paper identifies major types of semi-enclosed spaces and monitors their thermal performance in northern and southern Europe. The results showed that a wide range of thermal conditions, namely cooler conditions during summer and warmer conditions during winter can be experienced in both regions. Moreover, the thermal variation, which was identified, is linked with the spatial identity of each space and it is argued that the degree of enclosure as well as the orientation and the urban context are significant temperature determinants. Intermediate, semi-enclosed urban spaces should be regarded as important urban components that could increase the thermal and spatial diversity of the urban fabric and therefore contribute to a more fulfilling and comfortable environment.

Temporary uses of vacant urban spaces are usually not foreseen in conventional urban planning and have often been linked to economic or political disturbances. In New Zealand, Christchurch’s vacant spaces came into existence after the city was hit by several devastating earthquakes in 2010 and 2011. Parallel to the ‘official’ rebuild dis- course, temporary uses have emerged on vacant post-earthquake sites including community gardens, urban agriculture, art installations, event venues, eateries and cafés, and pocket parks. Based on the review and analysis of exemplary transitional community-initiated open spaces and correlated literature, the paper looks at how the post-disaster urban context in Christchurch has influenced particular aspects of temporary urbanism in comparison with case studies in non-disaster environments. By focusing on the anticipated benefits of community-initiated open spaces, the paper dis- cusses the relevance of temporary uses of vacant urban spaces for urban sustainability in relationship to concepts of community resilience and raises questions about possible long-term values.

In a context of increased urban competition, art and culture are often used by cities world-wide as tools to improve their image and make urban spaces attractive. In that process, art is—as we will argue—becoming a new urban norm, which is normalizing not only urban space and experience, but also art itself. By contributing to the pacification or securization of public spaces, art could encourage some behaviors or, on the contrary, discourage others. Reversely, this normative dimension of urban art could impact art itself, especially by redefining the limit between artistic forms that are either inclusive or exclusive, dominant or subversive. Through examples found during PhD fieldwork in Montreal and Johannesburg, we will demonstrate that this normalization of the city through art and of art through the city takes place in various urban contexts, that it questions the distinction between Northern and Southern cities, and the definition of a (global) city itself.

The climate of a city influences the ways in which its outdoor spaces are used. Especially public spaces intended for use by pedestrians and cyclists, such as parks, squares, residential and shopping streets, and foot- and cycle-paths will be used and enjoyed more frequently when they have a comfortable and healthy climate. Due to a predicted global temperature rise, the climate is likely to be more uncomfortable in the Netherlands, especially in summer, when an increase in heat stress is expected. As the phenomenon of urban heat islands (UHI) aggravates heat stresses, the effects will be more severe in urban environments. Since the spatial characteristics of a city influence its climate, urban design can be deployed to mitigate the combined effects of climate change and UHI’s. This paper explores these effects and tries to provide tools for urban design and strategies for implementation. Consequently, the applicability of the design tools is tested in a design for two existing Dutch neighbourhoods.
