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 promotion of quality of life is becoming ever more important in a scenario of regional, national and even international competition among cities, triggered by globalization. Public sites, and green spaces in particular, which are available in varying extent in all urban areas, can bring important benefits to urban vitality and, as a consequence, to quality of life. However, cities are intricate entities and measuring their success in converting the potential for public green space usage into increased quality of life is a difficult task. In order to contribute to the objective of assessing the potential for public green space use, and its consequences on urban vitality, we applied the Data Envelopment Analysis technique to assess a total of 174 European cities. The results detect the best performing cities, and for the cities considered inefficient, a set of benchmarks is identified, whose best practices can be copied to support efforts of performance improvement.

As Malaysia's population continues to grow and becomes more concentrated in urban areas, the important benefits of urban green spaces to the environment, the economy, and the health and well-being of city residents become even more significant in counterbalancing some of the negative effects of the country's urban development. With this concern in mind, the authors designed a social survey for urban planners and landscape architects in Kuala Lumpur to identify and study their views on the nature, roles, and benefits of urban green spaces; the problems associated with protecting urban green spaces in Kuala Lumpur; and the attributes of green spaces they thought were most important when considering how much priority a particular green space should be given for preservation. Kuala Lumpur provides a particularly interesting case study as a rapidly growing city in a developing country with a tropical climate - a context in which there has been relatively little research on urban green space, despite the importance of shade in very hot climates. In addition, Kuala Lumpur has experienced a great loss of green space in recent decades, both on its periphery from urban expansion and around the city center from the drive (fueled by economic growth) to use central land more intensively.

The popularity and impact of the High Line in New York mirrors the complex reality of contemporary provision of public space. The development of the project, its relation- ship to its surroundings and the evolving trend of elevated parks are analyzed in relation to the role of urban green space and impacts of Landscape Urbanism. The High Line shows the way to a new role for urban green space by utilizing abandoned infrastructure. In analysing the narrative of the High Line, this article stresses the importance of understanding localities and connectivity. Based on observations as well as a review of the literature and media, the article concludes that great landscaping does not create great places without careful consideration of the surrounding community and residents.

Results from an inner-city teen focus group on parks and urban green space in Los Angeles, California and responses to parallel questions posed to adults from the same area show striking differences. While adults focused on activities and cited a need for additional recreation-oriented parks for teens, teenagers themselves focused on greened spaces suitable for socializing and relaxing. Teens were also keenly interested in local parks, aware of maintenance issues, and concerned about personal safety.

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.

Problem, research strategy, and findings: Parks provide important physiological and psychological benefi ts to seniors, improving their quality of life; they are particularly important for low-income, inner-city seniors who lack access to open and green space. However, seniors do not often use parks partly because park design and programming are not responsive to their diverse needs and values. To identify what low-income, inner-city seniors seek and value in neighborhood parks, and to provide guidance to planners on how to better design senior-friendly parks, we conducted a literature review and held focus groups with 39 low-income, ethnically diverse seniors in an inner-city neighborhood in Los Angeles (CA). We asked these seniors about their preferences as well as the challenges and barriers they encounter in using neighborhood parks. Seniors report many impediments to park use; they are not provided appropriate programming that allows opportunities for socializing, safety, and security within the park and along access routes; opportunities for exercise and walking; and aesthetic and natural elements that provide contact with nature.Takeaway for practice: Park planners and designers should seek to incorporate senior voices in park design and programming in four ways by developing appropriate programming sensitive to diverse needs, accommodating the desire for �seniors-only� parks, promoting security and safety in the park and along access routes, and offering open and green space. We also fi nd the need for additional research on seniors from different racial and ethnic backgrounds.

Contemporary provision of open spaces within cities rests largely on professional assumptions about its significance in the lives of residents. This paper presents results from the Greenwich Open Space Project which used qualitative research with four, in-depth discussion groups to determine the design of a questionnaire survey of households in the borough. The research shows that the most highly valued open spaces are those which enhance the positive qualities of urban life: variety of opportunities and physical settings; sociability and cultural diversity. The findings lend some support to the approach of the urban conservation movement but present a fundamental challenge to the open-space hierarchy embodied in the Greater London Development Plan. The Project identifies a great need for diversity of both natural settings and social facilities within local areas and highlights the potential of urban green space to improve the quality of life of all citizens.

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.

Situating itself in encounter and public space debates and borrowing from non‐representational theory approaches, this paper uses data from the authors' 2‐year Economic and Social Research Council research project to consider how local urban parks can work as sites of routine encounter, mixity, and place belonging. The paper explores how parks as green public spaces are important as sites of inclusive openness while the materiality of parks is a key dynamic in affective encounter processes. Parks can work as animators of social interactions, participatory practices, and place affinities across ethnic and cultural difference. The paper concludes that the concept of convivial encounter can be extended to incorporate the concept of elective practices – choosing to be in shared public space can generate connective sensibilities that are not necessarily contingent on exchange. In using parks as a lens to examine localities and diversity, the paper critically reflects on research practices for understanding and describing heterogeneous formations of multiculture and outlines how the project's research design and the fieldwork methods sought to carefully and appropriately undertake research with complexly different places and populations.

This article provides a sociological explanation for urban “greening,” the normative practice of using everyday signifiers of nature to fix problems with urbanism. Although greening is commonly understood as a reaction against the pathologies of the industrial metropolis, such explanations cannot account for greening’s recurrence across varied social and historical contexts. Through a study of greening in Germany’s Ruhr region, a polycentric urban region that has repeatedly greened in the absence of a traditional city, I argue that greening is made possible by a social imaginary of nature as an indirect or moral good, which I call urbanized nature, that is an outcome of, and subsequently becomes a variable in, urbanization. I draw on processual accounts of urbanization and the sociology of morality to explain urbanized nature’s emergence in the Ruhr at the beginning of the twentieth century, and its use to fulfill two competing visions of urban democracy in the postwar period. I find that rather than an ideological reaction against cities, greening is an aspirational practice that can be mobilized by a range of actors in a variety of places and times. By showing how a new social imaginary made new forms of moral action possible and how those ideals were then materialized in urban space, this article draws attention to the role of cultural imaginaries in urban change and to the material consequences of moral beliefs.
