Ghats have come about as a response to religious, spiritual and social needs along the water edges in India and have become places of human congregation. This study is limited to the main ghat area of the waterfront in Ujjain, a historic city and a significant Hindu spiritual center in India. The objective is to identify forces that underpin and threaten this valuable environment and propose strategies that could be implemented to salvage it. Research was conducted through detailed examination of physical aspects of the urban public realm, activity patterns and environmental conditions. Text, data and drawings were systematically collected through various sources. Key concerns are discussed in the light of current thinking on the subject to propose strategies and draw up conclusions for necessary conservation and revitalization to take place.

In recent years, local activists in the Global North and South have been organizing to improve degraded and abandoned spaces in marginalized neighborhoods by creating parks, playgrounds, urban farms, or community gardens. This paper integrates existing knowledge on urban place attachment and sense of community with scholarship on environmental justice in order to understand the role of place attachment in environmental mobilization in distressed neighborhoods across political systems and urbanization contexts. It examines the different forms of connections that activists develop and express toward neighborhoods with long-time substandard environmental conditions and how their experience of the neighborhood shapes their engagement in environmental revitalization projects. This comparison of three neighborhoods in Barcelona, Boston, and Havana shows that activists in all three places intend for their environmental endeavors to express grief at the loss of community, fears of erasure, and emotional connection and feelings of responsibility to place. To address environmental trauma, they aim to construct nurturing, soothing, “safe havens,” recreate rootedness, and remake place for residents.

Business Improvement Districts (BIDs) provide supplemental services to urban commercial corridors using funds from member assessments. They have become a very popular urban revitalization tool, but their formation is still largely unexplained. Theory implies that BIDs will form if they add to aggregate welfare and if the marginal net benefit of membership is positive. I test this for the neighborhood overall and at the BID boundary. Using unique, micro-level and longitudinal data from New York City, I employ survival analysis methods to estimate the likelihood of a neighborhood forming a BID. I then estimate the likelihood of the marginal property’s BID membership by comparing the characteristics of properties located immediately inside and outside of the BID boundaries. I find that BIDs are more likely to form when there is more commercial space over which the BID benefits can be capitalized and when there is homogeneity in service and spending preferences across properties. BIDs also tend to form in neighbor- hoods that possess signs of appreciation and growth. Generally, BIDs are more likely to form in neighbor- hoods with higher valued properties with the exception of very wealthy areas. The BID boundary, however, is comprised of relatively less valuable properties.

Latino immigrant presence in urban neighborhoods has been linked with reduced neighborhood cohesion in social disorganization-based ethnic heterogeneity hypotheses and enhanced cohesion in immigration revitalization approaches. Using the 2000–2002 Los Angeles Family and Neighborhood Survey and the 1994–1995 Project on Human Development in Chicago Neighborhoods Community Survey, we explore the association between Latino immigrant concentration and both levels of, and agreement about, neighborhood collective efficacy. Findings from multilevel models with heteroskedastic variance indicate that Latino immigrant concentration exhibits a nonlinear association with collective efficacy. At low levels, increases in Latino immigrant concentration diminish collective efficacy, consistent with a heterogeneity hypothesis. The negative association between Latino immigrant concentration and collective efficacy declines in magnitude as immigrant concentration increases and, particularly in LA, becomes positive beyond a threshold, consistent with an immigration revitalization effect. We also find an inverse nonlinear pattern of association with the variance of collective efficacy. At low levels, increasing Latino immigrant concentration increases the variance of collective efficacy (reflecting more disagreement), but beyond a threshold, this association becomes negative (reflecting increasing agreement). This pattern is observed in both LA and Chicago. The prevalence of social interaction and reciprocated exchange within neighborhoods explains a modest proportion of the Latino immigrant concentration effect on mean levels of collective efficacy in Chicago, but does little to explain effects on the mean in LA or effects on the variance in either LA or Chicago. These findings offer insight into the complex role Latino immigrant presence plays in shaping neighborhood social climate.

Public policies supporting market-oriented strategies to develop mixed-income communities have become ascendant in the United States and a number of other countries around the world. Although framed as addressing both market goals of revitalization and social goals of poverty deconcentration and inclusion, these efforts at 'positive gentrification' also generate a set of fundamental tensions - between integration and exclusion, use value and exchange value, appropriation and control, poverty and development - that play out in particular concrete ways on the ground. Drawing on social control theory and the 'right to the city' framework of Henri Lefebvre, this article interrogates these tensions as they become manifest in three mixed-income communities being developed to replace public housing complexes in Chicago, focusing particularly on responses to competing expectations regarding the use of space and appropriate normative behavior, and to the negotiation of these expectations in the context of arguments about safety, order, what constitutes 'public' space, and the nature and extent of rights to use that space in daily life.

In this article the ambivalence of public policy responses to diversity on the street are documented empirically through a detailed case study of the marginalization of youth from the downtown public spaces of Portland, Maine, USA. Urban planners, architects and property developers have become increasingly concerned with improving the quality of urban life and the public spaces on which it depends. They argue that urban revitalization initiatives must embrace diversity — cultural and economic, as well as functional and spatial. This diversity of different ‘diversities’ is often under‐theorized, as are the benefits of, and relationships among, social and cultural diversity, economic diversification, mixed‐use and multi‐purpose zoning, political pluralism, and democratic public space. It is my contention that this ambivalence is not simply a smokescreen for vested commercial interests, but also provides opportunities for expressing alternative visions of what diversity and the city itself should be. Looking specifically at youth, I explore a relatively underexamined aspect of inner‐city diversity. While there is a relatively well‐developed literature about the contested place of low‐income groups, racial minorities and the homeless in urban redevelopment initiatives, youth have largely been ignored.

Since the 1970s, certain types of upscale restaurants, cafés, and stores have emerged as highly visible signs of gentrification in cities all over the world. Taking Harlem and Williamsburg as field sites, we explore the role of these new stores and services (“boutiques”) as agents of change in New York City through data on changing composition of retail and services, interviews with new store owners, and discursive analysis of print media. Since the 1990s, the share of boutiques, including those owned by small local chains, has dramatically increased, while the share of corporate capital (large chain stores) has increased somewhat, and the share of traditional local stores and services has greatly declined. The media, state, and quasi-public organizations all value boutiques, which they see as symbols and agents of revitalization. Meanwhile, new retail investors—many, in Harlem, from the new black middle class—are actively changing the social class and ethnic character of the neighborhoods. Despite owners’ responsiveness to community identity and racial solidarity, “boutiquing” calls attention to displacement of local retail stores and services on which long-term, lower class residents rely and to the state’s failure to take responsibility for their retention, especially in a time of economic crisis.

Jane Jacobs's The Death and Life of Great American Cities (1961) had an enormous influence on urban design theories and practices. This study aims to operationalize Jacobs's conditions for a vital urban life. These are (1) mixed use, (2) small blocks, (3) aged buildings, and (4) a sufficient concentration of buildings. Jacobs suggested that a vital urban life could be sustained by an urban realm that promotes pedestrian activity for various purposes at various times. Employing multilevel binomial models, we empirically verified that Jacobs's conditions for urban diversity play a significant role with regard to pedestrian activity.

The way urban solids relate to urban voids, the spatial relations of urban space itself and all other characteristics that define urban space are paramount in determining human distribution in any given community. This determines social relations that in turn reproduce spatial relations. This kind of process determines what sort of community and hence environment that is eventually generated. It is the intention of this paper to establish urban variables and hence urban patterns that promote human distribution, which in turn creates a sustainable community. A further intention is to establish a language that could be used to generate policies and design rules for such communities.

The general aim of this paper is to demonstrate the significance of intentional soundscape design in urban squares by investigating people’s general perceptions of urban soundscape and sound preferences, and the effects of demographic factors. An intensive questionnaire survey was carried out in two urban squares in Sheffield. Sound identification and classification were both considered. The results show that natural sounds as a group were generally preferred to urban sounds; the preferences of soundscape elements influenced people’s choice of using an urban square; and in terms of sound preference, the differences amongst age groups were rather significant, whereas between males and females only slight differences were found. Finally, some suggestions on soundscape design in urban squares are given.

This paper proposes an essentially new theory of urban space based on information theory and the laws of optics. The use of urban space is linked to the information field generated by surrounding surfaces, and on how easily the information can be received by pedestrians. Historical building exteriors usually present a piecewise concave, fractal aspect, which optimizes visual and acoustical signals that transmit information content. Successful urban spaces also offer tactile information from local structures meant for standing and sitting. The total information field in turn determines the optimal positioning of pedestrian paths and nodes. This complex interaction between human beings and the built environment, incredibly neglected in our times, explains why so many historical urban spaces provide an emotionally nourishing environment.

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.

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.

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.

The study engages with the ways in which gender mix plays out in public spaces as a key issue in exploring social diversity and vitality of the urban public life. The paper introduces a mapping method to unravel how gender differences are spatially manifested in urban public spaces. Thus, urban mapping has been considered as a method for producing a kind of spatial knowledge that has the capacity to shed light on how different socio-spatial patterns play out in public open spaces. The proposed mapping method documents where and the extent to which female and male users appropriate urban public spaces. The database for developing and testing the proposed method emerges from two site areas in the city of Tehran. In doing so, the study draws upon direct observation, fieldwork notes, visual recording, and urban mapping as research methods. In this way, the paper raises questions about the importance of gender mix in public space and the ways in which mapping has the capacity to inform urban research.

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.

Temporary uses of vacant urban spaces are usually not foreseen in conventional urban planning and have often been linked to economic or political disturbances. In New Zealand, Christchurch’s vacant spaces came into existence after the city was hit by several devastating earthquakes in 2010 and 2011. Parallel to the ‘official’ rebuild dis- course, temporary uses have emerged on vacant post-earthquake sites including community gardens, urban agriculture, art installations, event venues, eateries and cafés, and pocket parks. Based on the review and analysis of exemplary transitional community-initiated open spaces and correlated literature, the paper looks at how the post-disaster urban context in Christchurch has influenced particular aspects of temporary urbanism in comparison with case studies in non-disaster environments. By focusing on the anticipated benefits of community-initiated open spaces, the paper dis- cusses the relevance of temporary uses of vacant urban spaces for urban sustainability in relationship to concepts of community resilience and raises questions about possible long-term values.

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.

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.
