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.

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.

In this symposium, we explore how urban citizenship is about expressing, if not producing, difference, and how fragmentation of claims affects urban citizenship and right to the city movements with their universal, all-inclusive ideals. Investigating social movements, political participation and conflicting diversities in public space in Tel Aviv and Berlin, we see a trend towards a diversification of interests, a weakening of movements, and even a competition over rights and resources rather than a development of mutual support and solidarities among various groups on the pathway to a livable city. This tension, we argue, deserves attention. Radical urban scholarship and politics need to better understand the historical and place-specific contexts that structure the formation of citizenship claims and the courses that citizenship struggles take. Celebrations of urban citizenship as a more contextualized, community oriented, and bottom-up framework (in comparison to national citizenship) should therefore be complemented by a careful investigation of their fragmented and fragmenting practices.

The main public spaces in European cities are the focus of much attention, whereas marginal public spaces are places of neglect and decline. The concentration of disadvantaged and vulnerable groups in limited spaces creates a sense of entrapment. The social fragments that have been put next to each other in deprived neighbourhoods, either by market forces or by public planning, start to crack in public places of these neighbourhoods. On the one hand, intensive use of space by some groups excludes and intimidates others. On the other hand, the limited amount of public space is under the threat of encroachment by other demands on a finite commodity. In these places of fragmentation and competition, communication is often difficult, if not impossible, as different social groups speak different languages, have different attitudes and have different frameworks. A public space that allows this diversity to become aware of itself through free expression can be a significant asset for such a diverse population. Improving public places can improve the actual conditions of life in these neighbour- hoods, while injecting a sense of hope and a better image in the eyes of residents and the outside world. Although a key part of good governance, there is no doubt that this should be put in perspective, as one among a number of issues that need addressing.

Recent years have seen a resurgence of interest in the relation between networks and spatial context. This review examines critically a selection of the literature on how physical space affects the formation of social ties. Different aspects of this question have been a feature in network analysis, neighborhood research, geography, organizational science, architecture and design, and urban planning. Focusing primarily on work at the meso- and microlevels of analysis, we pay special attention to studies examining spatial processes in neighborhood and organizational contexts. We argue that spatial context plays a role in the formation of social ties through at least three mechanisms, spatial propinquity, spatial composition, and spatial configuration; that fully capturing the role of spatial context will require multiple disciplinary perspectives and both qualitative and quantitative research; and that both methodological and conceptual questions central to the role of space in networks remain to be answered. We conclude by identifying major challenges in this work and proposing areas for future research.

Preferences for urban spaces were studied as a function of spatial category and nine predictor variables: spaciousness, refuge, enclosure, coherence, legibility, complexity, mystery, typicality, and age. A non-metric factor analysis of the preference ratings yielded four categories of urban spaces: Open-Undefined, Well- Structured, Enclosed Settings, and Blocked Views. These categories are similar to the spatial categories proposed for natural environments by S. Kaplan (1979, Assessing Amenity Resource Values. USDA Forest Service General Technical Report RM-68), who stressed openness and spatial definition as bases for categorization. The Well-Structured category was best liked, with the other categories not very well liked and about equal in preference. Regression analyses revealed three variables as consistent predictors of preference. Coherence and complexity were positively related to preference, and age was negatively related. Overall, the results support the Kaplans' proposal that both spatial and non-spatial factors are important in categorizing environments and in explaining environmental preferences.

Spatial synergy, as defined in this paper, is composed of characteristics of physical-spatial organization of the city which support the actions and behaviour of people, particularly in public space (supportiveness). Spatial synergy concerns the relationship between ‘things and things’, while supportiveness concerns the relationship between ‘people and things’. In the context of the city, things are buildings, technical facilities and plantings; people are the inhabitants and other users. Spatial synergy is achieved through a specific way of arranging buildings, technical facilities and plantings to form open spaces (space segments or places). It is achieved through the way these are interrelated (‘relation and communication’) within the urban fabric. It is also achieved through the degree of accessibility of all such defined places within a settlement unit (‘universal distance’). The physical-spatial characteristics that support actions and behaviour in public spaces (supportive characteristics) are simultaneously those towards which urban design should be directed, if it is to fulfil its purpose. In this context the author emphasizes the viewpoint, in contrast to the tradition of the Modern Movement, that public space has to be the decisive component in creating and developing settlement units that are habitable in the true sense.

Urban parks are usually studied as discrete, green public open spaces. Less studied is how parks are geographically distributed from a ‘spatial logic’ point of view, i.e. how they ought to be geographically distributed across the urban landscape. This paper evaluates the degree to which normative principles about park distribution are in evidence from the standpoint of three spatial goals: proximity, diversity and social need. Using Phoenix and Chicago as case studies, it offers an empirical example of how park distribution can be shown to conform (or not) to one or more distributive patterns. Descriptive measures show that Phoenix parks do not conform to any of these three distributional principles, while Chicago parks do somewhat better. In both cities, land uses surrounding parks heavily favour residential uses. In Phoenix, single-family homes are prioritized, making spatial distribution based on proximity, diversity or social need difficult. A strategy for acquiring a better spatial logic, within existing realities and constraints, is suggested.

Through a case study based in Bristol, this article explores how the law of place' has transformed multiple heterogeneous city centre spaces into a single homogeneous and commodified privately owned retail site. Drawing on de Certeau, Lefebvre, and humanistic geographers including Tuan, the article explores how law facilitates spatial and temporal enclosure through conventional understandings of private property, relying on techniques of masterplanning, compulsory purchase, and stopping up highways. It suggests that the law of place draws on binary spatial and conceptual distinctions to apparently separate places from spaces, applying different legal rules either side of an often invisible boundary line. The article questions this legally facilitated spatial and conceptual enclosure, particularly as it restricts spatial practices within the public realm. It concludes by rejecting an urban 'right to roam' as insufficiently transformative, calling for a broader interpretation of Lefebvre 's 'right to the

This paper examines the relationship between ethnic residential segregation and two components of the built environment: the geographic distribution of its elements and their spatial configuration (i.e., the spatial relations and visual access between those elements). This relationship is investigated through a case study of Arab-Jewish residential segregation in Jaffa. Statistical and structural analyses (Q-analysis) of this case show that the conjunction of elements having different meanings (symbolic, cultural, functional, etc.) with spatial and visual integration attributes provides varying conditions for the expansion of the Arab Jewish residential patterns, a process potentially affecting the geographic scale intensity of residential segregation. It was found, for example, that public land uses having relatively 'neutral' ethnic and symbolic meanings (e.g. commercial sites and parks) and spatially integrated with the surrounding urban environment tend to moderate residential segregation. Identification of the institutional character of the built environment—segregation/encounters in mixed ethnic areas—may contribute to a more socially oriented spatial policy.

The modern world is facing rapid urbanisation, increasing urban population, constant growth of cities and the construction of new neighbourhoods. Moreover, new neighbourhoods often lack the elements of identity in the context of the place and the people who live there. Therefore, it is necessary to construct these identities together with the physical and natural structure of place and the cultural identity of the people. The construction of spatial identities has been studied in two case studies of “new” neighbourhoods, Mađir (Banjaluka, Bosnia- Herzegovina) and Ilsvika (Trondheim, Norway), using a qualitative analysis method. The comparison makes use of a triangle model that includes three elements of identity construction as three points of analysis: a) spatial context, b) participation in processes of planning and construction and c) action in place. The two cultural contexts and two ways of constructing spatial identity in the new neighbourhoods studied show certain similarities and differences. The study points to the universal significance of this phenomenon and indicates that the process could be improved in each case by applying positive experiences from the other, with adaptation to the specific context. Considering the importance and interrelation of the three elements involved in construction of spatial identities, they should be harmonised in all stages of development.

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.

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.

Urban parks are community assets, providing people places to play and rest. Access to parks in urban environments promotes social equity and improves quality of life for surrounding neighborhoods. In this context, social equity is related to accessibility, i.e. the possibility of walking or biking from home to a public park, giving people who do not have access to a variety of entertainment an option that is a public good. This paper examines the spatial distribution of urban parks in the city of Curitiba, Brazil, and how it relates to the socio-economic conditions of surrounding neighborhoods. Curitiba is known for its urban parks; however, no systematic study has been conducted to verify which neighborhoods enjoy park access within walking distance and what the socio-economic differences are between the better and worse served neighborhoods. In addition, we investigate if access to green open space has improved between the last two decennial census, a period marked by unprecedented socio-economic affluence in Brazil. Research questions, to be addressed using spatial analysis, focus on equitable distribution, and spatial evolution of parks and social equity. Variables include measurable walking distances from census tracts to parks, income data from the 2000 and 2010 Brazilian decennial censuses, and qualitative data of urban parks in Curitiba. Findings offer recommendations for future implementation of additional parks in Curitiba so that all areas of the city have adequate green open space and all citizens have equal access to recreation and leisure opportunities.

As a growing number of social media platforms now include location information from their users, researchers are confronted with new online representations of individuals, social networks, and the places they inhabit. To better understand these representations and their implications, we introduce the concept of the “spatial self”: a theoretical framework encapsulating the process of online self-presentation based on the display of offline physical activities. Building on previous studies in social science, humanities, and computer and information science, we analyze the ways offline experiences are harnessed and performed online. We first provide an encompassing interdisciplinary survey of research that investigates the relationships between location, information technology, and identity performance. Then, we identify and characterize the spatial self as well as examine its occurrences through three case studies of popular social media sites: Instagram, Facebook, and Foursquare. Finally, we offer possible research directions and methodological considerations for the analysis of geocoded social media data.

As one of 725 UNESCO World Heritage Properties, Antigua, Guatemala, is subject to local international regulations related to building codes and how streets and public places are occupied. These regulations are discussed within the theoretical framework of spatial governmentality to explore that relationship between governance and Maya street vendors’ economic practices. I situate the scholarly discussion of spatial governmentality within a specific economic context by highlighting how street economies are affected by what Foucault calls the “era of ‘governmentality,’” especially in an ethnographic context. In this article, I argue that horizontal and vertical forms of governmentality affect the economic practices of street vendors within Antigua’s sociopolitically constructed spaces. Understanding how spatial governmentalities work in a particular place helps explain why street economies persist and why new ones emerge. In Antigua’s case, a new mobile form of street vending emerged because of newly implemented municipal regulations and policing priorities.

Recent critiques of conventional poverty research have highlighted the need to move beyond the conceptual limitations of “neighborhood effects” models and the use of the tropes of “adaptation” or “resistance” to explain the behaviors and actions of the urban poor. We use ethnographic field observations and interviews with public-housing residents to address these limitations in the poverty literature, assess competing explanations of poor people’s agency, and provide insight into the importance of space as a mediating link between macrostructural constraints and locally situated behaviors. We theorize agency and identity as spatial phenomena—with spatial attributes and spatial influences—and examine how different spatial meanings and locations enable or constrain particular forms of social action and behavior. Our ethnographic and interview data depict several strategies by which residents “use space” to provide a measure of security and protection, to designate and avoid areas of criminality and drug activity, and to challenge or support the redevelopment of public housing. From these data we show that urban space is not a residual phenomenon in which social action occurs, but a constitutive dimension of social life that shapes life experiences, social conflict, and action.
