The phenomenon and increasing rate of urbanisation is causing many researchers to look deeper at life in cities. Increasingly recognised are the benefits of urban green space and their associated recreational parks and nature reserves. While there is a growing literature on the environmental services provided by these areas; so too is there a growing literature on the numerous social benefits that recreational green spaces in particular afford their users. Although imagined and generally designed as salubrious public spaces, many parks often fall short of this. In fact research has shown that a park's design, its surroundings, and its management can all combine to exclude certain types of people. In this study I conducted ethnographic research to participate in and observe the activities of visitors to False Bay Nature Reserve in Cape Town. False Bay Nature Reserve includes a series of nature reserves and the Cape Flats Waste Water Treatment Works, and is situated in the area of Cape Town known as the Cape Flats. Much of the Cape Flats is beset by poverty, unemployment, and violent drug - related crime carried out by notorious gangs. Despite the challenges of the surrounding areas, my study reveals that False Bay Nature Reserve provides relative safety to its users as well a range of enjoyable re creational activities. Some of the key recreational activities are separated distinctively between two key sites in the reserve. Furthermore the visitors of these sites differ markedly in race, ethnicity and income. The legacy of apartheid almost certainly accounts for much of this separation; however, the study indicates that the barriers of this legacy are eroding and can potentially be further dismantled with engaged and informed management strategies. Due to its surroundings, the reserve is vulnerable and recently experienced a period where crime was prevalent, vegetation was overgrown, and it was feared by many of its users, particularly women. The reserve had in many ways become what researchers call a landscape of fear, a not so uncommon description of parks around the world. However, management and the majority of visitors feel the reserve has recovered from this period. This is in large part due to upgrades that improved recreational facilities and security in the reserve. Accounts from visitors high light how important a sense of safety is for people frequenting this reserve, most of who live in nearby neighbourhoods. The reserve still faces some challenges today, but is a significant asset to the City of Cape Town and many of its more marginalised residents. This study challenges much of the literature on the benefits of urban green space and associated parks. It shows that particularly in cities of the Global South such as Cape Town, parks require specific management strategies that prioritise safety and in doing so promote and ensure inclusivity for all.

In an increasingly urbanised world, addressing the need for access to urban green space has become a pertinent topic of interest. In Cape Town, South Africa, a city of immense biodiversity and unique spatial development, the issue of accessing urban green spaces is particularly important. Environmental and ecological advocates call for conservation of green space, to preserve the rare biodiversity of the region, while pressures for continued development to accommodate the City's growing population override land conservation policy aspirations. The legacy of post-apartheid development is still strongly entrenched in Cape Town, resulting in an inequitable and in efficient city form. Access to quality green space remains problematic in Cape Town. This research seeks to discover how accessible urban green spaces are in Cape Town, and, if barriers exist, whether they are physical, economic, or socially driven. The author has undertaken a case study method approach to conduct this research, focusing on eight nature reserves or conservation areas managed by the City of Cape Town in the southern and eastern suburbs of the City. Key informant interviews (n= 6) were conducted, as well as qualitative and quantitative surveys of park users and the general public. Park users (n= 672) were surveyed on site, at one of the eight green spaces, while the public (n= 317) were surveyed at the nearest commercial shopping area adjacent to the green space. Outcome measures included demographic information, suburb of residence, mode of transport, reasons for choosing mode of transport, frequency of green space visits, and reasons for visiting. Results show the majority of park users accessed the green space by personal vehicle, and very few park users took public transport (n= 3). The majority of users resided in suburbs within two kilometre s of the green space. Park users varied in age, yet young adults aged 16-19 and elderly over the age of 80 accounted for only 2.8% and 1.8% of those surveyed, respectively. The ethnic breakdown of those surveyed was not indicative of Cape Town's ethnic breakdown, according to the 2011 Census, with white South Africans and coloured South Africans accounting for 50% and 39%, respectively. Over a quarter of the public surveyed identified 'lack of information' or 'unaware of what park offers' as the reason for not visiting the green space. Safety and security was a common concern among both park users and the public; many expressed concern about visiting the green space alone, or traveling alone due to issues of security in the adjacent neighbourhoods. From the data gathered in this research, the author concludes that barriers exist in the access of quality green spaces within Cape Town, and include, but are not limited to, issues of proximity, public transport, safety and security, spatial development of the City, varied green space interests, and information barriers. These issues vastly alter how users engage in these eight different green spaces. Further research may be conducted in a more expansive study on Cape Town's green spaces, including small local green spaces in neighbourhoods throughout the City, which may yield interesting results on the access and barriers to access of urban green spaces.

The health benefits of nature are numerous, wide-ranging, and often overlooked. An ever-growing body of research has started to document, substantiate, and even in some cases quantify the significance of interacting with nature and its effect on human health and well-being. These directly measurable health benefits are also compounded in urban environments by environmental and social benefits. For example, the inclusion of green spaces in urban communities has been shown to reduce violence. Green spaces are important for overall health, but also specifically for healing. The benefits of natural spaces in hospitals has been explored in the literature and shown to benefit not only patients but also family and visitors, as well as staff, by creating a healing and restorative environment that helps to reduce stress and alleviate anxiety. Lack of green space in urban communities is creating and exacerbating health disparities. Urban hospitals are often limited in their ability to include extra space, and particularly green space, in their campus, yet it is their patients who need these healing benefits the most. Particularly urban communities of low socioeconomic status are often those with the least access to green spaces, or only have access to low-quality, poorly maintained, unsafe green spaces. Yet the residents of these communities are those who stand to benefit the most from access to nature and a greener environment. Improving the accessibility, quality, safety, and square footage of natural green spaces in urban environments will help improve health equity by mitigating negative effects of the urban built environment on health and well-being, increasing the agency of these communities to live healthier lives, and allow them to reap the physical, emotional, and social benefits of green spaces. / Urban Bioethics

In the UK, urban parks face a precarious future and, with projected cuts of over 65% to local authority discretionary funding (Local Government Association, 2012:2), it is ever more important to understand their value. This study interrogates the value of these resources from the perspective of the individual and, through a mixed method comparative case study of two community parks in Leeds, West Yorkshire, identifies four key challenges to existing framings of their significance. Drawing on primary observational, social survey and interview data, boundaries constructed between forms of value are, firstly, problematized with fluidity recognised between use and non-use aspects. Secondly, a range of previously-omitted past-related values are identified. Negative elements of significance are, then, thirdly, highlighted as heavily interwoven with positive accounts of importance and emphasised as key omissions in prior representations of value. Before, finally, value is stressed as spatially relative, with comparison with other leisure resources noted as an inherent facet of accounts. Taken together, these challenges demarcate an individual perspective of value as notably distinct from those levelled at other scales, such as the firm or community, as it emphasised that, from this perspective, the value of a resource must be rethought as a relational property created in the interaction between people and their environment, rather than an absolute property assigned to a space. Organisations, such as Nesta (Neal, 2013:21) have emphasised a need to ‘rethink' the funding and management of urban parks, moving towards “mixed funding models”, incorporating some level of community voluntarism. This assumed involvement is, however, premised on community engagement which is far from certain. As such, there is a pressing need to understand the value attached to urban parks to understand the scope for expectations of voluntarism to be truly fulfilled.

This thesis starts from the proposition that the ingrained perception of urban green space as being synonymous only with fairly well maintained amenity parkland is too narrow and generally overlooks the many environmental and social benefits that other types of green space and their natural habitats bestow on urban residents and wildlife. A critical review of the literature on the benefits which different kinds of green space confer on urban residents in environmental, social, health and well being and economic terms confirms the need for a more holistic approach to the study of green spaces in cities and also highlights the need to develop and realise a more comprehensive "ontology" of urban green space in tropical countries, a fundamental task which is a main concern of the present thesis. From reviewing the classification schemes or typologies used in different countries to formally recognise and to distinguish different types of green space, the author develops a new, expanded typology for urban green space adapted to Malaysian conditions, aiming to use this as far as possible as a framework to categorise the green spaces of Kuala Lumpur (KL). KL provides a particularly interesting case study as a rapidly growing city in a developing country with a tropical climate, a context where there has been relatively little research on urban green space, despite shade being particularly appreciated in very hot climates. Also KL has experienced much loss of green space in recent decades: on its periphery from urban expansion; and around the city centre from the drive, fuelled by economic growth, to use central land more intensively. The main empirical analysis in the thesis uses data obtained from remotely sensed satellite images of high resolution (from the IKONOS satellite) to try to identify all vegetated forms of land cover in KL and to discern their nature, primarily whether trees, shrubs or grass, regardless of their location, using object oriented software to process the IKONOS data. The degree to which the different types and functions of green space can be identified from IKONOS imagery using both semi-automated and manual methods of visual interpretation is then compared. The results show that, using high resolution IKONOS imagery, it is not possible to identify unambiguously all the types of green land use or green land cover that are found in the proposed, new typology of green space, either by using semi-automatic classification or by visual interpretation, although the latter enables more types of green space to be distinguished with confidence. A key result of the preceding analysis, nevertheless, is to produce maps of green space showing the foregoing 3 classes of vegetation (plus water, bare ground and built up areas) for the entire city in very fine detail using first a semi-automated classification followed by selective manual revision. This produces a more complete picture of the geography of these 3 basic types of green space across the whole city than the typical picture purely or mainly of public parks generated from the typologies used by city governments in developing countries, including KL, simply reflecting their traditional concerns being largely restricted to the latter kinds of green space. These finely detailed maps showing the complex mosaic of green space are, in some respects, the most important result of the thesis. These maps of green space produced from satellite data are linked in a geographic information system (GIS) with data on land use for small land parcels and, using dasymetric methods, with data on population from the census to produce a range of alternative, illuminating perspectives on the nature and extent of green space across the whole city, often at a very fine geographical scale, and including an analysis of the relative provision (or lack thereof) of green space over the whole city; this also yields insight into the role of particular green spaces in the wider urban system. Subsequently, the use of GIS operations enables officially recognised green spaces and the even more extensive and diverse areas of green space not officially recognised to be mapped and examined separately, possibly for the first time in KL. A social survey designed mainly for urban planners and landscape architects in KL was carried out mainly to learn and study their views on the nature, roles and benefits of urban green space, on the new expanded typology, on the problems of protecting urban green space in KL and on what attributes of green spaces they considered should be seen as most important when considering how much priority a particular green space should be given for preservation. From some 38 environmental and social criteria the 41 respondents considered very important, 31 criteria (13 environmental and 18 social) were chosen as attributes to use in evaluating 17 different green spaces of various types in different parts of the city through assessment on site by a small team of trained assessors. A smaller subset of 4 environmental and 3 "social" (actually all accessibility) criteria, selected from the foregoing 31 criteria, was identified which could be estimated "remotely" by "desk based" methods i.e. by using the satellite data and the population data held in our GIS, as well as by direct field survey. It was then possible to compare the 3 sets of evaluations for the 17 green areas in the form of overall rankings in turn on the environmental and then accessibility criteria: firstly the ranks of the sites on all 13 environmental criteria, then on the subset of 4 environmental criteria (both of the latter from field assessment) and finally on the same subset of 4 criteria estimated "remotely". The equivalent overall rankings for the 18 social amenity criteria, then the subset of 3 accessibility indicators from field observation and lastly the same subset of 3 but estimated remotely were then compared. The results showed clear similarities and strong correlations between the three sets of evaluations for the 4 environmental criteria measuring aspects of vegetative cover and "green connectivity" but less consistent similarity for the social and accessibility measures, with only weak correlations between rankings on the field and remote estimates for the 3 accessibility indices. The main conclusion is therefore that "remote" evaluation could potentially have a useful role, complementary to ground surveys, in monitoring and assessing green spaces as regards some key environmental criteria and, more debatably, may also be able to provide useful measures of accessibility, which are difficult to estimate from field visits. However, observation on site is necessary for assessment of nearly all the social criteria relevant to evaluating urban green spaces.

The objective of this paper is to provide a robust understanding of the magnitude and direction of effect of urban green space on human health outcomes. This relationship has been studied using a variety of health and green space measures and multiple approaches to collect health data. Due to the various approaches used to study the relationship between green space and health, it is difficult to clearly understand the general relationship. In order to have a robust and clear understanding of the relationship between green space and human health, it is necessary to do a meta-analysis that considers all the approaches to assessing green space, health, and health data. Overall, the average estimated effect shows that surrounding urban green space improves human health by 1.14 fold (~u=0.13 (95% CI: (0.07-0.19)). The magnitude of effect increased when accounting for perceived health and when using greenness as the urban green space measure (~u=0.29 (95% CI: (-0.06-0.63)). In conclusion we can now objectively imply that health can be improved with increased surrounding green space. Further, that the magnitude depends on how studies assess green space and health measures, as well as how health data is collected.

Sustainable Development challenges will increasingly concentrate in cities as the urbanization in Europe and the rest of the world continues and governments must implement policies to ensure benefits of urban growths are shared sustainably. When more people move into the cities, the intimate contact with nature is lost since nature has not always been a priority in the history of urban planning. A biophilic approach is considered in this study, where the concept of inclusion of nature is perceived essential for the human life and previous empirical evidence supports the theory of presence of nature being substantial to human wellbeing. Because of the population density, Paris is an interesting example of the development of a megacity in a post-Kyoto context. The development project for the Paris urban area, called Le Grand Paris, intends to develop Paris on several levels. The aim with this study is to examine driving forces for nature as a part of an urban setting that can contribute to the development of intelligent sustainable urban planning for the future. Using qualitative methods to gather empirical data and a discourse analytical framework, this study intends to increase the understanding of perspectives, incentives and discords in the perceptions of urban green space and Sustainable Development. The problem statement is: How is urban green space carried out in the perspectives of cultural, economical and ecological values of citizens and planning documents in the context of Le Grand Paris project? The results establish that that need of increasing vegetation in the city of Paris is pressing in order to enhance quality of life and increase effects of ecological services. The continuing urbanization of Paris will intensify the need of social-ecological interactions, which require approaches through processes of democracy and participation in order to contribute to intra- and intergenerational socio-ecological justice for a sustainable Paris.

This thesis explores characteristics of loose space and their implications for physical activity. A space becomes loose when an individual is using it for something other than what it was intended. Individuals can pursue a range of physical activities not possible in other public spaces. To assess the compatibility between loose space and physical activity a survey of 27 users of loose space and key informant interviews from public health, municipal parks and landscape architecture disciplines were used. Interview findings suggest that unstructured forms of physical activity are more likely to be adopted and maintained while survey results show 70% of loose space users are achieving recommended physical activity levels. Multifunctional space that can accommodate appropriation and change may have design implications for improving health. Design recommendations and strategies were developed to inform the design and management of loose space for physical activity. This study suggests that the qualities and distribution of loose space could improve adoption and maintenance of physical activity.

The primary objectives of this study are to understand if and how cities are adapting to heat and water stress and to characterize their understanding of the potential tradeoffs associated with vegetation-based strategies. I address these objectives using two approaches: a comparative analysis of climate adaptation and sustainability planning documents in cities vulnerable to heat and water stress and an in-depth case study of the response to heat and water threats in Los Angeles. The comparative analysis of city plans builds a broad understanding of how cities are planning to adapt to heat and water stress and the degree to which they articulate an understanding of, and mitigate the potential for, maladaptive measures. The Los Angeles case study provides the opportunity to more deeply trace how the process of adapting to heat and water stress has unfolded in a single city. To do so, I locate the city’s contemporary policies in an historical continuum with previous municipal environmental policy efforts, in local patterns of urban development and their entailing political and economic foundations, and in regional, state, national, and international environmental policy hierarchies.

This thesis sets out to explore how immigrant women encounter urban green spaces in Istanbul and Stockholm in their everyday lives. Underlying this focus is the importance of urban green spaces’ in providing a sustainable future and a healthy life for all and inequalities in accessing these spaces. Considering a lack of focus on gender and power dynamics in the environmental perception studies and urban green spaces, this thesis inductively explores how women encounter and experience urban green spaces and how power shapes these experiences by adopting a feminist epistemology and methodology through the use of in-depth interviews and qualitative GIS. Using Google Earth as a qualitative GIS method allows for non-verbal expressions to come forward during the interviews and creates a more collaborative and inclusive research process in line with a feminist methodology adopted in this thesis. My findings further contribute to how to practically design inclusive urban green spaces. The findings show that the cultural and gendered constructions of urban green spaces shape how these spaces were experienced by the women participants. The findings also show that body is an important source of knowledge in understanding how women encounter and experience these spaces. Through understanding the role of gender and culture in shaping these spaces and hence the experiences, my findings contribute to scholarship on the accessibility of urban green spaces. How my research participants experience green spaces in the case study locations highlighted the need to understand accessibility beyond physical proximity
