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.

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 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.

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 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.

Drawing on recent developments in field theory, this article analyzes the struggle for survival of São Paulo’s street vendors in the face of a massive eviction campaign. I conceive of street vending as a social field divided into two unequal categories—licensed street vendors and unlicensed street vendors—and show that responses to the campaign varied along group lines. Unlicensed peddlers either abandoned the field or drew on local networks to continue peddling under harsher conditions, whereas licensed street vendors relied on well-established ties to actors in the political field. After these ties proved ineffective, licensed street vendors survived thanks to the intervention of a non-governmental organization (NGO) that activated the judicial field and mobilized the legal capital vested in the licenses. The linkage role performed by this actor with cross-field networks and expertise shows the strategic import of interfield relations, which replicate and reinforce the unequal distribution of assets inside the field.

Recent work on entrepreneurial urban governance has focused on the new forms of exclusion produced by neoliberal entrepreneurial urban strategies, arguing that local forms of social–spatial organization are being dismantled through practices ranging from the privatization of urban public space to the emergence of gated communities. By exploring the role of agency amid these changing structures of constraints, this article interrogates processes of socio-spatial exclusion under entrepreneurial forms of urban governance. I argue that despite constraints placed upon different groups of affected citizens, excluded groups develop survival strategies that enable them to maintain a livelihood and in some cases empower them to thrive. I use the case of a recently implemented entrepreneurial policy in Mexico City called the Programa de Rescate (The Rescue Program). The prime objective of the policy is to revitalize and beautify the streets, buildings and central plaza of the city's Historic Center. Although this policy seeks an improvement in the quality of life for the local population, it excludes particular forms of social interaction that are central to the well-being of a large sector of the population, particularly street vendors who rely on public spaces for their daily survival. I use the case of the Programa to show how street vendors have struggled to remain on the streets of Mexico City's Historic Center.

Despite the fact that virtual environments are increasingly deployed to study the relation between urban planning, physical and social disorder, and fear of crime, their ecological validity for this type of research has not been established. This study compares the effects of similar signs of public disorder (litter, warning signs, cameras, signs of vandalism and car burglary) in an urban neighborhood and in its virtual counterpart on the subjective perception of safety and livability of the neighborhood. Participants made a walking tour through either the real or the virtual neighborhood, which was either in an orderly (baseline) state or adorned with numerous signs of public disorder. During their tour they reported the signs of disorder they noticed and the degree to which each of these affected their emotional state and feelings of personal safety. After finishing their tour they appraised the perceived safety and livability of the environment. Both in the real and in the simulated urban neighborhood, signs of disorder evoked associations with social disorder. In all conditions, neglected greenery was spontaneously reported as a sign of disorder. Disorder did not inspire concern for personal safety in reality and in the virtual environment with a realistic soundscape. However, in the absence of sound disorder compromised perceived personal safety in the virtual environment. Signs of disorder were associated with negative emotions more frequently in the virtual environment than in its real-world counterpart, particularly in the absence of sound. Also, signs of disorder degraded the perceived livability of the virtual, but not of the real neighborhood. Hence, it appears that people focus more on details in a virtual environment than in reality. We conclude that both a correction for this focusing effect and realistic soundscapes are required to make virtual environments an appropriate medium for both etiological (e.g. the effects of signs of disorder on fear of crime) and intervention (e.g. CPTED) research.

This study examined patterns of activity in street-side public spaces in one city. Eye-level videotape was employed to document public activity, characteristics of the population and characteristics of the downtown street-side surroundings. A scheme for organizing the data is presented. Patterns of use, disaggregated across activities, groups and time periods were derived, and limitations and implications are discussed.

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.

We examine 5,603 property transactions in Jefferson County, Alabama that take place between 2004 and 2008. Using OLS regressions, we estimate the extent to which differences in walkability, as measured by Walk Score, can explain the variability in land values. We find that after controlling for population growth and lot size, land values generally increase with walkability and that this result is stable over time. However, we find evidence that this impact reverses as neighborhoods become more car-dependent. This car dependency increases as the distance from the central business district increases. We consider the implications of our findings on mixed-use developments in what we believe is the first study to address walkability in this context of sustainable development.

In the US and western Europe, mixing policies are widespread. They aim to differentiate various income-groups in deprived neighbourhoods. By constructing 'expensive' housing units, the middle classes are encouraged to settle in these neighbourhoods and consequently a concentration of low-income-groups is circumscribed. Such a new population composition is assumed to lead to an improved quality of life in the neighbourhood concerned. However, insufficient attention is paid to ethnicity and interethnic dynamics; these aspects will be elaborated on in two case studies of deprived and ethnically differentiated neighbourhoods in Amsterdam. Furthermore, this paper will also explore the impact of ethnic differences and perceptions on the social contacts and interactions between various ethnic groups of residents.

Around the world, there is increasing concern with the ways in which different populations use public spaces and places. Focusing on the French context, this paper investigates conceptual difficulties inherent in the co‐occupation of space by different population groups. The focus is to shed light on the ordinary engagement of teenagers in a working‐class neighbourhood in terms of differentiated social practices according to gender, age, social network, the physical and social morphology of the neighbourhood, and relational and situational criteria. Their occupation of space is channelled by public policies as well as educational, family, and socio‐educational care that structure their time and space. However, this paper highlights also the subjective dimension. Manipulating the ‘regime of familiarity’ and the ‘regime of regular planning’, teenagers learn through experimentation to use the ‘regime of justification’, thus challenging adult spatiality in terms of their moral and political involvement. The deliberate and involuntary characteristics of their occupation of space transgresses the accepted uses of public space and disturbs adults. Their actions produce discomfort, which adult residents express through distancing practices. Teenagers recall various situations of general dissatisfaction that they are unable to synthesise in a complaint with reference to a general problem, and they express this feeling through stronger transgressions. Low‐level conflict between adults and teenagers is thus self‐perpetuated. Furthermore, teenagers' occupation of space is differentiated between girls and boys, between the ‘cool’ teenagers and the ‘geeks’, the teenagers from the neighbourhood and those from the outside, those who ‘have origins’ and those who do not. This generates unpleasant reciprocal disturbance and an everyday conflict that is further perpetuated by the failure to frame this disturbance as a public problem.
