As the obesity epidemic in children increases, it is important to consider the role of neighborhoods in supporting children's physical activity and healthy development, especially in low- income communities where obesity levels among children are higher than for their middle-income counterparts. I present a participatory and qualitative GIS approach to mapping children's own perceptions and use of their neighborhood for physical activity with ten and eleven year-olds growing up in a diverse low-income community in Denver, CO. Girls walk shorter distances to and use different types of community spaces for play and recreation from boys, some of which is explained by the differing environmental-socialization approaches employed by parents and carers. Children's perceptions of risk align spatially with features of the built environment, but do not correlate with reported crime. Results illustrate the utility of qualitative spatial analysis to understand relationships between children's perception, the built environment, and social factors that shape children's active transport, leisure, and recreation in their neighborhood. Children's local knowledge should be valued and solicited in community-level health and planning interventions to promote physical activity.

The rise of mobile food vending in US cities combines urban space and mobility with continuous online communication. Unlike traditional urban spaces that are predictable and known, contemporary vendors use information technology to generate impromptu social settings in unconventional and often underutilized spaces. This unique condition requires new methods that interpret online communication as a critical component in the production of new forms of public life. We suggest qualitative approaches combined with data-driven analyses are necessary when planning for emergent behavior. In Charlotte, NC, we investigate the daily operations, tweet content, and spatial and temporal sequencing of six vendors over an extended period of time. The study illustrates the interrelationship between data, urban space, and time and finds that a significant proportion of tweet content is used to announce vending locations in a time-based pattern and that the spatial construction of events is often independent of traditional urban form.

Cities around the world have marked differences in spatial form and structure. To some extent this can be attributed to cultural differences. However, the impact spatial form has on the interactions within and between residents of different neighbourhoods is unclear. This paper calls on empirical evidence collected in the Walled City of Ahmedabad, India, home to Hindu and Muslim residents in distinct neighbourhoods for centuries. Employing Space Syntax method, this paper reveals significant differences in how public spaces are spatially laid out by these two communities. Muslim neighbourhoods have a spatial structure typical of a naturally evolved settlement, where the most integrated spaces are clustered centrally. In contrast, Hindu neighbourhoods have an ‘inside-out’ pattern, with the most integrated spaces located at the neighbourhood edge. The cultural significance of these distinct forms is discussed alongside the relationship between the neighbourhoods and the rest of the city. These findings on spatial structure could have an important role in Ahmedabad’s urban planning . A better understanding of how public space relates to lifestyle and culture could contribute to improved community relations. It could also contribute to dealing successfully with communal conflict, economic development, social sustainability as part of Ahmedabad’s future urban planning strategies.

Analysis of property sales in the vicinity of 1,294-acre Pennypack Park in Philadelphia indicates a statistically significant rise in land value with closeness to park, when allowance is made for effect of type of house, year of sale, and special characteristics such as location on corner of block. Location rent due to the park ranges from approximately $11,500 per acre 40 feet from the park to $1,000 at 2,500 feet. It accounts for 33 percent of land value at 40 feet, 9 percent at 1,000 feet, and 4.2 percent at 2,500 feet. Each acre of parkland may be said to generate a value of $2,600 in location rent.

Focusing on imaginaries of the ideal city is an important method to illustrate the power of ideas, imagination, representations, and even visions, and how these dimensions influence the way in which cities are organized and lived. In this article, we argue that one current and important city imaginary in a Swedish context is the gender-equal city. In this imaginary, the gender-equal city becomes a symbol for the open, tolerant, bustling, safe city, a city aiming to attract the middle and creative classes. However, at the same time, the imaginary of the ideal, gender-equal city is highly ambiguous. The ambiguity will be discussed throughout the article. Based on present planning projects in the city of Umea in Sweden, we will discuss how the imaginary of the gender-equal city is presented, filled with meaning and used in place marketing, with the overall ambition of discussing the possibilities and pitfalls of what we call the gender-equality planning strategy. The aim of the article is to study how the city of Umeå is acting to create a gender-equal city and what kind of imaginaries these practices build on. The material consists primarily of a case study focusing on projects that aim to create an equal city, and also includes analyses of policy documents and media reports. This study illustrates how imaginaries are produced through local projects and different imaginaries provide different spaces for politicizing gendered power relations.

As urbanization progresses, open space becomes structured as units of progressively smaller sizes and with more pronounced physical and functional boundaries. This paper analyzes these Open Space Units (OSUs) in Flanders, and seeks how size of open space units, hence also spatial fragmentation, affects the evaluation of these units. The results clearly confirm a ‘fragmentation bias’, meaning a lower valuation of smaller units, which leads to a strategic gap and land use uncertainty concerning large stretches of area with high degree of fragmentation. This valuation is confronted with the contrasting and positive values expressed in a strategic open space project by local stakeholders about a typical peri-urban remnant open space unit. Overcoming the ‘fragmentation bias’ in open space valuation is a continuing challenge in planning and open space policies, especially in highly urbanized environments.

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.

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.

Within the International debates about the roles and relevance of planning and architecture, urban design is trying to find its place and clarify its contribution to city making. The products and the practice of urban design vary significantly in different global and socio-economic contexts and in relation to varying theoretical foundations. In South Africa, as in other developing countries, urban design is only beginning to feature as a valid mainstream concern within city development and among built environment practitioners. This paper presents the case of the City of Cape Town’s Dignified Places Programme as an example of implementation-focused urban design undertaken in a context where the conscious design and management of the public realm does not feature on the agendas of cash-strapped, basic needs-focused local government. The design and construction of new public spaces is the focus of this programme, but a parallel objective is to place the central concern of urban design – the quality of the public environment – squarely on the agenda of local government in Cape Town. The paper outlines the urban context in which it is being implemented sketches the issues that prompted its initiation and traces its theoretical origins focusing on the linkages between this theory and practice. The paper gives an account of the origins, objectives and strategy as well as the design principles that directed the form and location of the projects in the Programme. The paper finally reflects on the key successes and challenges of the programme and attempts to tease out lessons for both the theory and practice of urban design.

Leisure preferences and open space needs were explored within a discrete, homogeneous ethnic community: the Chinese Americans of Chicago's Chinatown. Face-to-face interviews and focus group discussions were used to identify outdoor leisure patterns and preferences, in general, and with respect to new park development being planned for the community. Findings show that although some popular activities are no different from what might be expected for the mainstream Anglo American population, the meaning and significance of these activities have clear and unique ties to Chinese culture. Preferences for the new Chinatown park development mirror activity preferences, emphasizing facilities that enhance the natural environment for passive activities. Notable differences in activity preferences were found within the sample of respondents according to age, generational status, and other factors. Park planning considerations and future research needs are identified.

This article examines interstices in the urban fabric using the example of two urban leftover spaces in Paris. The article first analyzes the institutional mode of treating these spaces, which explains the ‘framing’ of the interstice as a temporary functionless space. It shows how interstices are not only institutionally created and controlled, as opposed to free, but also find a functional place as a temporary margin of maneuver in a process of decay, recycling and renewal enforced by landlords, the police and maintenance teams. Second, the article examines the improvised modes of action developed by diverse people in order to use the interstice. The article looks at what happens in the gaps of urban planning, when activities find a place in the interstice not in order to transform it, and bring it back into the realm of urban places, but to take advantage of its ‘in-between’ position in the city. In practice, such activities are led by individuals who have to be ‘just passing’, because the frame (Goffman, 1974) built by landlords and their agents prevents them from taking place. Under some conditions, ‘just passing’ can give way to another type of involvement described as ‘out of frame’, which in this case, allows a group of homeless people to settle in the interstice for a more durable period of time despite heavy surveillance.

Soundscape is about relationships between the ear, human beings, sound environments, and society. Soundscape research is interdisciplinary. On the basis of a series of case studies in Europe and China and an intensive literature review, the soundscape description, evaluation, and creation in urban open spaces are systematically examined, in terms of four basic elements: sound, space, people, and environment. Factors affecting soundscape evaluation in urban open spaces, including acoustic - psychological - social characteristics of various sounds, acoustic effects of space boundaries and elements, social - demographic characteristics of users, and general physical - environmental conditions, are identified, and, consequently, a system for soundscape description is established. Potentials of creating and designing soundscape in urban spaces are then discussed in terms of sound and space.

The purpose of this paper is to take part in the debate about power relationships in contemporary cities between the agents of urban renewal and the local communities, as mediated by cultural and artistic interventions and projects. Our study proposes a new conceptual frame, focused on the comparison between two notions of heterotopia as theoretical alternatives for the interpretation of cities as social and participatory spaces. The notions we consider may be traced to two key thinkers such as Michel Foucault and Henri Lefebvre, and lay the foundation for alternative analytical paradigms of the contemporary urban condition, in relation to artistic and cultural practices in the public space. We draw upon these two alternative readings of heterotopia to explore the implications of the interaction of artistic practices with the urban space as a contested terrain from the viewpoint of power relationships. In our analysis, we find that Foucault's notion of heterotopia is potentially conducive to top-down planning processes and to gentrification. Lefebvre's notion is instead possibly more suited to participatory practices as strategies of reactivation of the right to the city.

Safety and security are essential components of urban public space management, particularly since September 11, 2001. Although security is necessary for creating spaces the public will use, making it a top priority is often criticized for restricting social interaction, constraining individual liberties, and unjustly excluding certain populations. This study examines legal, design, and policy tools used to exert social and behavioral control in publicly accessible urban spaces. Based on a review of the relevant literature and extensive site visits to spaces in New York City, we create an index that uses 20 separate indicators in four broad categories to quantify the degree to which the use of a space is controlled. Since comparable instruments do not exist, we propose our index be used to evaluate publicly accessible spaces. We suggest several potential applications useful in planning practice and for testing theories about public space.

This paper examines how the decentralization of state power and, advent of mayoral elections in Bogota ́, Colombia, enabled municipal government, with the help of a cadre of professional planners and designers, to transform the city socially and physically by reinventing civil society and public space. Three contiguous mayoral administrations used public space as a setting and tool to reinvent a culture of citizenship as well as to demonstrate competency on behalf of the mayors. The mayors’ strategy was largely successful as Bogota ́ has experienced a move from individualism to collective spirit, and citizens report improvements in civility, friendliness and quality of life. Much of the city’s success derives from the vision of the mayors and the important role urban planners and designers provide in implementing that vision. By examining Bogota ́’s transformation, it is possible to better understand how local politicians and planning and design administrators are key to that change.

This paper reports on a research study that examined if and how older adults use urban waterfront promenades for physical activity. The research involved case studies of three waterfront promenades in Vancouver, British Columbia. Research methods included field observations and surveys. The findings conclude that older adults use Vancouver's waterfront promenades in significant numbers, overwhelmingly for walking; that more of them walk with others rather than alone; that nearness to home may be a determining factor as to which promenade they use; and that the most important environmental characteristics of promenades may be well-separated walking and biking paths, trees, shade when it's hot, and sun when it's cool.

Based primarily on an observational study, this paper addresses privately owned and managed public space at the Tjuvholmen waterfront development in Oslo. To date, no other research has been published internationally on external private-public space in a Nordic context. The four factors or processes dealt with are planning and development, design, management and, in particular, use. The main finding is that Tjuvholmen’s public spaces are characterized by ‘tightness’ and reduced publicness. As such, they share key characteristics with private-public spaces described in the literature from the US and the UK, while in some other respects they also deviate from these.

This article presents commentary and analysis on the Urban Studies special collection on the night-time city. The collection highlights burgeoning interest in the urban night from across the social sciences and helps consolidate what might be referred to as the ‘third wave’ of research on the evening and night-time economy (ENTE). The collection addresses the challenges of 21st cen- tury place-making after dark in a variety of international contexts. This commentary interprets individual contributions to this collection in the light of the author’s research experience within an evolving and increasingly sophisticated field of knowledge. The articles have, I suggest, power relations, social exclusion and social sustainability as their most prominent meta-themes. I pro- pose a new conceptual model for the interpretation of situated assemblages of power, capacity and influence, as operating across four overlapping modes of urban governance.

Uses and perceptions of nine nearby, easily-accessible outdoor areas were studied by interviewing 89 residents of a multiple-family housing development. Judgments of perceived sizes, size adequacy, use frequencies, preferences, and perceived importance were elicited, along with descriptions of personal uses. The findings reveal consistent differences between three general types of areas which serve distinct functions. The yards serve territorial needs, the common areas and public athletic fields afford recreational opportunities, and a nearby wooded area with a pond provides a highly preferred setting for a variety of nature-related pursuits. Although most ratings varied across the different types, ratings of perceived importance were high for each. The findings of this study clarify the relationships among physical size, use patterns and preferences for different areas. They also illustrate the diverse affordances of different urban nature areas, and emphasize the important role that nature contacts play in the everyday lives of urban residents.

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.
