Infrastructure convenes social relations, thereby revealing how city dwellers access shared resources in the context of growing inequality. Our exploration of migrant infrastructure engages with how highly variegated migrant groups develop a ‘transaction economy’ (Simone, 2004) within marginalised city streets, exchanging goods and services, and information and care. In the context of ethnically diverse and deprived urban places, where state resources are increasingly diminished, we explore how a precarious yet skilled resourcefulness emerges through the street. Our empiri- cal exploration of migrant infrastructure is located on Rookery Road in Birmingham and on Narborough Road in Leicester, and draws on qualitative surveys with 195 self-employed proprie- tors from many countries of origin. The streets reveal transaction economies that intersect local and migratory resources, eluding the categorisation of cities associated with either a global North or a global South. Further, the lively nature of street transactions decentres western- centric measures of economic value. From the street, we develop a postcolonial analysis of infra- structure that relates properties of historic depth (power), socio-spatial texture (materiality) and locality (place).

This paper investigates migrant domestic workers as a marginalised group in Singapore's urban landscape by examining the ways in which their social maps are structured and negotiated in relation to public space. It argues that the phenomenon of the 'divided city' evident in capitalist societies which reflects and reinforces the sexual division of labour in general is even more salient in the lived experiences of migrant female domestic workers who must contend not simply with the spatial expressions of patriarchy, but also with racialisation and other means of segregation. However, it is clear that these women are not entirely passive recipients of dominant practices and ideas, but are capable of different styles and strategies in the use, colonisation and even contestation of public domains.

This article focuses on the dynamics between migrant street vendors and public security forces and the complex social production of urban public space in Guangzhou. As an answer to daily contestation of public order, security agencies reluctantly open flexible windows of business opportunities to hawkers. Zones and periods of control, ‘soft’ approaches, and categories of ethnic belonging influence everyday governance and accessibility of public space. This results in a transient public space, fluid and continuously changing, which offers a new perspective on openness and functioning of public space in urban China.

Gulf cities have witnessed rapid urban growth where new migrant communities from various cultural backgrounds have been evolving over the last two decades. This paper explores perceptions of liveable urban environments in Qatar’s capital city, Doha. An attitude survey of 280 migrant professionals from different cultural backgrounds engaged in the high service sector was conducted. A profile for each cultural group including westerners, middle easterners, Indians and Southeast Asians was developed to analyse the way in which the key liveability factors are perceived. Factors were classified into two overarching categories: urban life and urban spaces. Urban life category included aspects that pertain to traffic and movement experience, residential satisfaction, shopping experience, and satisfaction regarding leisure and service spaces. Urban space category included attractiveness, iconicity and familiarity, which were attitudinally explored in four public open spaces. The inquiry has uncovered a number of concerns related to traffic experience, housing quality, parking spaces, school facilities and shopping opportunities. This may stymie the city’s global attractiveness success on the global stage while warranting the need for addressing liveability as a part of future development plans.

The research examines the shift from flood-resistant policies and plans to flood resilience. We use a case study of New Orleans since Hurricane Katrina to illustrate this unfolding process and the emergence of a "living with water" approach to green infrastructure. The article highlights the challenges of this shifting policy landscape through the case of the Lafitte Greenway, a green infrastructure project that transformed a three-mile corridor of underutilized public land into a linear park running through flood-prone neighborhoods. Through the experience of creating this greenway, planners in New Orleans learned valuable lessons about US disaster rebuilding policies and how to implement green infrastructure in urban neighborhoods.

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.

‘Green infrastructure’ is a term used to describe systems of parks, greenways, open spaces and other natural landscape elements that provide community benefits. Although we have some understanding of how people use parks and developed greenways, little has been documented about use of the undesignated public and private spaces along green infrastructure features such as stream corridors. The purpose of this research was to examine characteristics that may influence people’s use of undesignated open spaces along the stream corridors that form the skeleton of many green infrastructure systems. Data were obtained from a Recreational Use Attainability Analysis (RUAA), an evaluation performed for the Texas Commission on Environmental Quality. The RUAA was conducted for 85 survey sites along 243 km (151 miles) of streams in Houston’s Buffalo Bayou watershed. Results indicate that the proximity of stream corridors to local residents, the level of pedestrian access available and tree cover were the best predictors of recreational use while the presence of water, fish or other wildlife were not significant predictors. Observations also indicated that urban and suburban stream corridors afford a variety of recreational and aesthetic values to residents. Implications for policy, planning and design of green infrastructure are discussed.

This article explores how indigenous migrants experience the sociopolitical and existential condition of “illegality” in the United States. Drawing on the experiences of Maya migrants from Yucat´an, Mexico, in the San Francisco Bay Area, I argue that the specter of state surveillance and the threat of law enforcement produce a particular politics of (im)mobility for indigenous migrants. This local politics of mobility takes form through spatial tactics of invisibility and visibility. Tracing migrants’ tactical maneuvers through public space, I show how their relations to space, place, and movement alter cultural sensibilities of tranquilidad (tranquility), and further instantiate “illegality” as a site of exclusion. This analysis of the experiential effects of anticipated surveillance provides a deeper understanding of the power of the state to enforce migrant “illegality” even in cities that promise official sanctuary.

Australia is currently rolling out one of the most expensive and ambitious infrastructure projects in the nation’s history. The National Broadband Network is promoted as a catalyst for far-reaching changes in Australia’s economy, governmental service provision, society and culture. However, it is evident that desired dividends, such as greater social engagement, enhanced cultural awareness and increased civic and political participation, do not flow automatically from mere technical connection to the network. This article argues that public institutions play a vital role in redistributing technological capacity to enable emerging forms of social and cultural participation. In particular, we examine public libraries as significant but often overlooked sites in the evolving dynamic between digital technology, new cultural practices and social relations. Drawing on interviews and fieldwork across the public library network of the state of Queensland, we attend to the strategies and approaches libraries are adopting in response to a digital culture.

Over recent decades, cities have been radically transformed by information and communication technologies (ICTs) that modify people’s daily lives by reorganising mobility, infrastructure sys- tems and physical spaces. However, in addition to the role that technology plays in the develop- ment of the infrastructure in our cities, it is also being used ‘as a means of control’. This view of technology as a disciplinary tool that restructures space, time and the relations among activities has been promoted by scholars who have shown that technology is also a means of saturating and sustaining contemporary capitalist societies and deepening inequalities. However, the situa- tion is far more complex than that. Technology is not only used top-down but also bottom-up, with individuals using technological devices to share and enhance their visibility in space. This bidirectional paradigm – of vertical surveillance and horizontal sharing – contributes to a sense of ‘being exposed’ in public space that normalises practices of sharing personal data by individuals and thus results in diminished privacy. This argument is supported by an experiment conducted on smartphone users that includes personal interviews and the use of a smartphone Android application that combines online tracking with experience sampling. The findings show a conver- gence between the online and offline worlds (a ‘public’ situation in the offline world is also consid- ered as such in the online world), which is a condition that contributes to the normalisation of ‘asymmetrical visibility’. Based on these results, the paper ends with a discussion of the contem- porary meaning of public space.

This article examines park use in relation to neighborhood social (safety and poverty) and urban form (pedestrian infrastructure and street network pattern) characteristics among youth and adult subpopulations defined by age and gender. We utilized System for Observing Play and Recreation in Communities (SOPARC) and Geographic Information Systems to objectively measure park use and park and neighborhood characteristics in 20 neighborhood parks. Heterogeneous negative binomial regression models indicated that the relationship between park use and types of activity settings, and park use and neighborhood attributes vary by age and gender. In general, the study found that park and activity setting size; activity settings such as playgrounds, basketball courts, pool and water features, shelters, and picnic areas; and availability of sidewalks and intersections in the park’s neighborhood were positively associated with park use, whereas crime, poverty, and racial heterogeneity of the surrounding neighborhood were negatively associated with park use.

The Irvine Minnesota Inventory (IMI) was designed to measure environ- mental features that may be associated with physical activity and particularly walking. This study assesses how well the IMI predicts physical activity and walking behavior and develops shortened, validated audit tools. A version of the IMI was used in the Twin Cities Walking Study, a research project measuring how density, street pattern, mixed use, pedestrian infrastructure, and a variety of social and economic factors affect walking. Both bivariate and multivariate analyses were used to assess the predictive value of the IMI. We find that while this inventory provides reliable measurement of urban design features, only some of these features present associations with increased or decreased walking. This article presents two versions of shortened scales—a prudent scale, requiring association with two separate measures of a physical activity or walking behavior, and a moderate scale, requiring association with one measure of physical activity or walking. The shortened scales provide built environment audit instruments that have been tested both for inter- rater reliability and for associations with physical activity and walking. The results are also useful in showing which built environment variables are more reliably associated with walking for travel—characteristics of the sidewalk infrastructure, street crossings and traffic speeds, and land use are more strongly associated with walking for travel, while factors that measure aesthetics are typically less strongly associated with walking for travel.

The popularity and impact of the High Line in New York mirrors the complex reality of contemporary provision of public space. The development of the project, its relation- ship to its surroundings and the evolving trend of elevated parks are analyzed in relation to the role of urban green space and impacts of Landscape Urbanism. The High Line shows the way to a new role for urban green space by utilizing abandoned infrastructure. In analysing the narrative of the High Line, this article stresses the importance of understanding localities and connectivity. Based on observations as well as a review of the literature and media, the article concludes that great landscaping does not create great places without careful consideration of the surrounding community and residents.

This paper emerges from an ethnography of the economic and cultural life of Rye Lane, an intensely multi-ethnic street in Peckham, South London. The effects of accelerated migration into London are explored through the reshaping and diversification of its interior, street and city spaces. A ‘trans-ethnography’ is pursued across the compendium of micro-, meso- and macro-urban spaces, without reifying one above the other. The ethnographic stretch across intimate, collective and symbolic city spaces serves to connect how the restrictions and circuits of urban migration have different impacts and expressions in these distinctive but interrelated urban localities. The paper argues for a trans-ethnography that engages within and across a compendium of urban localities, to understand how accelerated migration and urban ‘super-diversity’ transform the contemporary global city.

In this paper, I adopt a concept of informal public space from socialist social life as part of the language of postsocialism to explore changing uses of social space by women in contemporary Hồ Chí Minh City. Following Zdravomyslova and Voronkov, I describe the informal public as the space in culture where urbanites are able to demonstrate normality and belonging by participating in neighborhood life. I argue that the use of informal public space has been adapted to meet the new conditions of the post-reform era. Because of this, the informal public is simultaneously a space where urbanites not only can demonstrate belonging but also can mark relative social position by producing or mitigating social distance.

This study investigates outdoor recreation participation within a multifunctional landscape, a UNESCO Man and Biosphere Reserve. The reserve, the Kristianstad Vattenrike located in southern Sweden, has made a deliberate effort to make the experience of biodiversity possible for residents and visitors. Recreation is a key part of the biodiversity conservation effort in the area, represented by the infrastructure of the Kristianstad Vattenrike's 21 visitor sites. Given the biosphere reserve context, this study investigates the question of whether there is a relationship between outdoor recreation participation and place attachment. Survey data was collected using concurrent application of multiple sampling strategies including both probability and purposive sampling of local adult residents of the biosphere area. Quantitative analysis showed a significant positive relationship between the level of outdoor recreation participation and place attachment. Qualitative data supported this relationship with more details about place attachment within the studied area. The study confirms a relationship between place attachment and outdoor recreation and provides insight into how the biosphere reserve context supports this relationship. The results of this study show that significant biodiversity management in close conjunction with outdoor recreational opportunity can be achieved and provides opportunities for human engagement and experience of biodiversity. Management Implications: This research can help managers design recreational settings that support biodiversity conservation goals. Our research found that: • A leading motivation for outdoor recreation participation is nature experience and this motivation can be used by managers to highlight a biodiversity conservation interpretive message in the design of outdoor recreation infrastructure. • Providing proximate access to nature based outdoor recreation, to support deliberate and direct experience of biodiversity, is an important component of engaging the public in biodiversity conservation. • Recreation proximity alone will not create public engagement in biodiversity conservation. However, proximity as a part of a deliberate institutional design including biodiversity conservation, sustainable development, and logistic support for research and monitoring may be critical for public engagement.

Landscape urbanism is articulated against the purported failures of traditional urban design practices to conceptualize adequately the transience, adaptability, and ecological complexity demanded by contemporary urbanism. This paper engages Giambattista Nolli’s 1748 map of Rome, a seminal example of the figure ground representational method, to highlight some contradictions in landscape urbanism’s texts and projects. Whereas the figure ground is often reduced to a binary black and white image, Nolli’s map illustrates the intertwining of public and private spaces, through rendering detailed attributes of site, infrastructure, history, and architecture. Also considered is the asser- tive restructuring of disciplinary influence within what Linda Pollak identifies as ‘con- structed ground.’ This reclamation constitutes a re-territorializing of landscape architecture through re-engagement of the urban fabric, as well as the more aspirational and necessary re-territorializing of design through intentional consideration of ecological complexity in the making of public urban spaces.

This article is based on a cross-national qualitative study of homeless and street-involved youth living within Olympic host cities. Synthesizing a Lefebvrian spatial analysis with Debord's concept of 'the spectacle', the article analyses the spatial experiences of homeless young people in Vancouver (host to the 2010 Winter Olympics) and draws some comparisons to London (host to the 2012 Summer Olympics). Tracing encounters with police, gentrification and Olympic infrastructure, the article assesses the experiences of homeless youth in light of claims made by Olympic proponents that the Games will 'benefit the young'. By contrast, the authors argue positive Olympic legacies for homeless and street-involved young people living within host cities are questionable.

The aim of this article is to explore new ways of integrating technology, nature and infrastructures into urban public spaces. This is done through a case study, the design of General Vara del Rey, which is offered here as a model to explore a novel urban political ecology that calls into question dominant definitions of public spaces as self‐contained sites operating independently of natural and infrastructural spaces. Through the double movement of ‘the technification of public space’ and ‘the publicization of infrastructures’, the square aims to rethink the political ecology of urban public spaces by enabling the effective incorporation and participation of infrastructural and natural elements as active actors into the public and political life of the community. It is argued that the transformation of infrastructures into fully visible, public and political agents provides a useful model to address the growing proliferation of infrastructural and technological elements onto contemporary urban surfaces and to open up the possibility of new forms of civic participation and engagement.
