Although a number of environmental and policy interventions to pro- mote physical activity are being widely used, there is sparse systematic information on the most effective approaches to guide population-wide interventions. Methods: We reviewed studies that addressed the following environmental and policy strat- egies to promote physical activity: community-scale urban design and land use policies and practices to increase physical activity; street-scale urban design and land use policies to increase physical activity; and transportation and travel policies and practices. These systematic reviews were based on the methods of the inde- pendent Task Force on Community Preventive Services. Exposure variables were classified according to the types of infrastructures/policies present in each study. Measures of physical activity behavior were used to assess effectiveness. Results: Two interventions were effective in promoting physical activity (community-scale and street-scale urban design and land use policies and practices). Additional information about applicability, other effects, and barriers to implementation are provided for these interventions. Evidence is insufficient to assess transportation policy and practices to promote physical activity. Conclusions: Because com- munity- and street-scale urban design and land-use policies and practices met the Community Guide criteria for being effective physical activity interventions, implementing these policies and practices at the community-level should be a priority of public health practitioners and community decision makers.

This article uses the Brazilian city of Belo Horizonte as a case-study to show that beyond the centralized planning model that prevailed in the 1970s, a new model of urban intervention has developed, based on the participatory budget and focused on the most vulnerable portion of the Brazilian urban population: the favela dwellers. While larger Brazilian cities such as Sa ̃o Paulo and Rio de Janeiro have a deeper history of intervention in the favelas, this article focuses on Belo Horizonte as the polar opposite to the well-known model of Curitiba. If we agree that any real sustainable urbanism should be built upon a participatory community, the favela’s interventions carried on in Belo Horizonte might rise to the occasion as a promising alternative.

Empirical urban design research emphasizes the support in vitality of public space use. We examine the extent to which a public space intervention promoted liveliness and three key behaviors that enhance well-being (“connect,” “be active,” and “take notice”). The exploratory study combined directly observed behaviors with self-reported, before and after community- led physical improvements to a public space in central Manchester (the United Kingdom). Observation data (n = 22,956) and surveys (subsample = 212) were collected over two 3-week periods. The intervention brought significant and substantial increases in liveliness of the space and well-being activities. None of these activities showed increases in a control space during the same periods. The findings demonstrate the feasibility of the research methods, and the impact of improved quality of outdoor neighborhood space on liveliness and well-being activities. The local community also played a key role in conceiving of and delivering an effective and affordable intervention. The findings have implications for researchers, policy makers, and communities alike.

There are numerous ways in which people make illegal or unauthorized alterations to urban space. This study identifies and analyzes one that has been largely ignored in social science: explicitly functional and civic-minded informal contributions that I call “do-it-yourself urban design.” The research, which began as an investigation into more “traditional” nonpermissable alterations, uncovered these cases—from homemade bike lanes and street signs to guerrilla gardens and development proposals—that are gaining visibility in many cities, yet are poorly accounted for by existing perspectives in the literature. This article examines the existing theories and evidence from interviews and other fieldwork in 14 cities in order to develop the new analytical category of DIY urban design. I present findings on the creators of these interventions, on their motivations to “improve” the built environment where they perceive government and other development actors to be failing, and on the concentration of their efforts in gentrifying areas. This introduces the possibility of conflict and complicates their impact. I argue that DIY urban design has wide-ranging implications for both local communities and broader urban policy.

This study investigated influences of residential street layout on neighboring. The study design was quasi-experimental with one pretest and two posttest measurements in an intervention group and two control groups. Data were collected using a recently developed questionnaire (MMN) and through field observations. The intervention implemented in this study was a transformation of three sections of residential streets into street parks, entailing considerable changes in street floor and spatial layout, provisions of street furniture like benches, planting of trees and flower beds, installation of play equipment, and prohibition of traffic and parked vehicles. Supportive acts of neighboring, neighbor annoyance, and children's play showed an overall increase in the intervention streets, interpreted as a sign of increased involvement in the neighborhood. Weak social ties and neighborhood attachment showed more complex patterns of changes, depending on demographic factors. It is suggested that symbolic effects of the changes may be more significant than functional effects, and thus that a change of neighborhood identity is an important mechanism.

This paper focuses on the development and meaning of informal social control experiences when strangers intervene face-to-face in instances of child punishment in public. The central question is, in the absence of formal authority and institutional resources, how do strangers construe wrongful punishment, negotiate deviant import, and manage control outcomes? Thirty-seven interviews were conducted with people who intervened on at least one occasion, and seven more with witness-participants. Interviewees described the meanings, events, and circumstances surrounding 50 acts of face-to-face intervention. The analysis focuses on some of the micro-political forces, such as claim themes and audience norms, that shape control outcomes. The interpersonal predicament for interveners reflects the cultural tension created when approval of physical punishment is widespread, when distinctions between normal and deviant punishment are ambiguous, and when interaction rules for informal intervention are not institutionalized.

Thermal comfort is an important issue to be considered in the design of urban squares. This study hypothesized that thermal experience can be affected by the perception of spatial structures and materials, which can be influenced by urban design. Therefore, surveys were conducted in three Dutch squares (in Den Haag, Eindhoven and Groningen, respectively) to identify relationships between people’s long-term thermal experience and three factors: width of the square, spatial openness and appearance of materials. The results reveal that all three factors have an influence: Dutch people experience thermal discomfort when spaces are ‘too wide’, ‘too open’ and consist of ‘cold’ materials.

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.

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.

The rejuvenation of public spaces is a key policy concern in the UK. Drawing on a wide literature and on qualitative research located in a multi-ethnic area of East London, this paper explores their relationship to well-being and social relations. It demonstrates that ordinary spaces are a significant resource for both individuals and communities. The beneficial properties of public spaces are not reducible to natural or aesthetic criteria, however. Social interaction in spaces can provide relief from daily routines, sustenance for people’s sense of community, opportunities for sustaining bonding ties or making bridges, and can influence tolerance and raise people’s spirits. They also possess subjective meanings that accumulate over time and can contribute to meeting diverse needs. Different users of public spaces attain a sense of well- being for different reasons: the paper calls for policy approaches in which the social and therapeutic properties of a range of everyday spaces are more widely recognised and nurtured.

This article examines the role of animals in the processes of social inclusion and exclusion in a gentrifying neighborhood. Residents who move into mixed-income, inner-city neighborhoods generally express a taste for diversity while simultaneously attempting to distance themselves from “undesirables.” Dogs allow newcomers to manage these tensions. The urge to control public spaces leads to the creation of new and quasi-exclusionary places, such as dog runs. At the same time, in the process of creating them, residents produce the neighborhood's image as a “diverse community.” Based on fieldwork conducted in a neighborhood of a large city in the northeastern United States, the author uses a wide range of discourse settings and genres to demonstrate that discursive production is part-and-parcel of the process of making places.

In the past five years the numbers of enclosed neighbourhoods have significantly increased in South Africa. These are existing neighbourhoods that are closed off through gates and booms across the roads. Many of these neighbourhoods are fenced or walled off as well, with a limited number of controlled entrances/exits, manned by security guards in some cases. The roads within these neighbourhoods were previously, or still are public property and in most cases the local council is still responsible for public services to the community within the enclosed neighbourhoods. In this way public urban space is privatised, whether formally or informally. I will explore the distribution of enclosed neighbourhoods in South Africa on a national scale and within two metropolitan municipalities, viz., the cities of Johannesburg and Tshwane. Then I proceed to highlight the nature and impact of these neighbourhoods on the privatisation of public space and draw on a wide basis of empirical data obtained through a national survey and in-depth case studies. Finally I will conclude with examples of lessons learnt from South Africa and how these may relate to international experience and future research on gated communities.

To what extent does the density of the tree cover in a city relate to the amount of social capital among neighbors? To address this question, we linked social survey data (N = 361) from the Baltimore Ecosystem Study with socioeconomic, urban form, and green space data at the census block group level using a geographic information system. We found a systematically positive relationship between the density of urban tree canopy at the neighborhood block group level and the amount of social capital at the individual level (r = .241, p < .01). Multiple regression analyses showed that tree canopy added a 22.72% increase in explanatory power to the model for social capital. This research adds a new variable—neighborhood tree canopy—to the typologies of green space that affect human social connection. Trees are a relatively inexpensive and easy intervention to enhance the strength of social ties among neighbors.

Models of urban planning after authoritarian modernism raise the question of democratic control over the city and the possibility of imagining as a collective act. The paper examines systemic hindrances to free-thinking, and thus free-acting, embedded in urban communities. Through the case study of recent work by the art collective Department of Play, it illustrates the rationale for engaging public imagination specifically via play as world-building; and it posits the potential implications and limits of such activity as an intervention into city planning processes. Interested in liminal spaces between territory, language and social affiliation, the collective advances an agenda of productive dissent in public space through play and performance. Department of Play begins from the position that we can only plan that which we imagine, and thus exists as an effort to free the public imagination from modes of thinking dictated by the capitalist context.

A medium-density planned neighborhood designed for a centrally located piece of urban land in the 1970s invoked some specific social-mix targets for the residential population of some 850 dwelling units. The site plan was developed in accordance with explicit planning principles derived from the Pattern Language by C. Alexander et al. A postoccupancy evaluation of residents' status, attitudes, and behaviors suggests that the design of a successful environment for a socioeconomic population mix involves a delicate balance between privacy and community. Such a balance is more complex and requires more careful design and more subtle innovation than the simple "if-then" logic of the Patterns used in planning this neighborhood.

Neighbourhoods may influence the health of individual residents in different ways: via the social and physical environment, as well as through facilities and services. Not all factors may be equally important for all population subgroups. A cross-sectional analysis of the Scottish Household Survey 2001 examined a range of neighbourhood factors for links with three health outcomes and two health-related behaviours. The results support the hypothesis that the neighbourhood has a multi-dimensional impact on health. There was also some evidence that the relationship between neighbourhood factors and health varied according to the population subgroup, although not in a consistent manner.

The growing proportion of human populations living in urban areas, and consequent trends of increasing urban expansion and densification fuel a need to understand how urban form and land use affect environmental quality, including the availability of urban green spaces. Here we use Sheffield as a case study of city-wide relationships between urban green space extent, quality (vegetation cover and tree-cover), and gradients in urban form and topography. The total area of buildings and length of the road network are equally strong negative predictors of extent of green space, while the former predictor is amore important negative influence upon green space quality. Elevation positively influences extent of green space but negatively influences tree-cover. In contrast, slope of terrain positively influences green space quality and is the best predictor of tree-cover. Overall housing density is a more important negative predictor of extent of green space and tree-cover than the densities of individual housing types. Nevertheless, the latter are more important influences upon levels of vegetation cover. Threshold effects of densities of different housing types suggest opportunities for optimising green space quality, with implications for housing policy. Variation in ecological quality of green space may partly reflect different historical intensities of industrial activity.

The recent flurry of research about arts‐led regeneration initiatives illuminates how contemporary arts festivals can become complicit in the production of urban inequality. But researchers rarely engage with detailed empirical examples that shed light on the contradictory role that artists sometimes play within these spectacularized events. Similar research in performance studies connects the political limits and potential of social practice arts — interventions that encourage artists and non‐artists to co‐produce work — as civic boosters strive to stage cities in order to attract investment. In this article, I explore the case study of Streetscape: Living Space at Regent Park, a participatory artistic intervention programmed in a public housing neighbourhood that is undergoing redevelopment in Toronto, Canada. Streetscape was part of the Luminato festival, an elite booster coalition‐led festival of ‘creativity’. I refer to these arts interventions to demonstrate how artists engaging in social practice arts can become complicit in naturalizing colonial gentrification processes at multiple scales. But I also reveal how artists can leverage heterogeneous arts‐led regeneration strategies to make space for ‘radical social praxis’ (Kwon, 2004), interventions that challenge hegemonic regimes. I conclude by interrogating the effectiveness of place‐based efforts in unsettling the ‘creative city’.

Informal commerce, characterized by market and street trading activities, thrives in the central areas of many Latin American cities. Focusing on the neglected spatial dimension of informal commerce, the paper traces its considerable expansion in the historic centre of Quito in Ecuador since the early 1970s and examines the issues which have prompted municipal intervention. An early municipal response involves some attempts at redistribution of informal commerce, justified by essentially functional issues such as hygiene and congestion. However, the introduction of conservation policy and the way this policy evolved to embrace a broad concern for the urban environment is associated with the emergence of an aesthetic/cultural discourse in attitudes towards informal commerce. The authorities are increasingly motivated towards ‘selling’ a new image of the historic centre and encouraging new economies oriented towards the tourist and a relatively wealthy clientele. Moves to exclude informal commerce have concentrated on the most visible spaces, particularly those of the principal squares. Although informal trade hidden from view continues to thrive, only time and further research will show whether the re‐presentation of the historic centre and the promotion of new economies will finally effect the exclusion of informal commerce as a culmination of long‐term efforts to control its occupation of space.

This study examines the first two years of a tactical innovation that emerged in 2012 in Egypt, which involved activist groups organizing patrol-type "intervention teams" to combat sexual violence against women in public spaces. Findings reveal that the new tactic took different forms in the two places in which it was deployed, even though the same actors employed it. I argue that the place in which a new tactic emerges shapes the form it takes. When coming up with a new collective action tactic, activists elaborate visions about how to carry out their actions based on their collective identities and taste in tactics. But as they start experimenting with the new tactic on the ground, they learn about the places' material affordances, symbolic valence, and power relations, as well as the constraints and opportunities that they represent. The material properties of places shape activists' possibilities of movement, patterns of communication, field of vision, and capacity to escape repression or reach safe spaces. The configuration of actors in a place shapes the nature of their interactions with others on the ground, possible alliances, and sources of conflict. The symbolic meanings of places shape the resonance of a group’s actions and the degree of resistance that actors face. Place in part determines the ability of activists to develop a tactic in the form that best fits their preferences.
