A comprehensive understanding of urban development is critical for moving towards the goal of sustainability. Despite a collection of urban sustainability indicator (USI) conceptual frameworks proposed and explored in practical urban sustainability assessment, establishing an integrated, well-quantified, spatially characterized USI model is still a challenging task. Therefore, based on a manuscript-style format this thesis develops a subjectively weighted integrated USI model and then applies it to the city of Saskatoon, SK, Canada, as a case study, based on quantifying a hierarchical index system. In addition, urban environmental sustainability is spatiotemporally investigated for an improved understanding of Urban Heat Island (UHI) effect. Results show that the proposed integrated USI model improved urban sustainability measurement by overcoming the shortages in existing USI models. Geospatial statistics demonstrated disparity in urban sustainability across residential neighbourhoods for Saskatoon in 2006 based on the significant clusters and outliers. It also found that population increases can possibly improve intellectual and economic well-being and promote urbanization, but may cause environmental degradation and lead to a decline in overall urban sustainability. This research also demonstrates that satellite imagery can be used to study environmental sustainability at different spatiotemporal scales. This research reveals that both urban water and green spaces had significant cooling effects on the surrounding urban LST within specific ranges. Urban surface temperature can be estimated based on a multiple linear regression model with sustainable traveling mode index and land use information as input variables. The overall significance of this research has three folds. First, it lays a preliminary theoretical foundation for a comprehensive understanding of urban sustainability based on a well-quantified integrated USI model. Second, it is relatively original with respect to improving urban sustainability measurements through the incorporation of subjective information into objective data. Third, this research has explored spatiotemporal analysis to detect urban sustainability patterns based on compiling multiple data sources using geospatial techniques. The proposed USI model is highly suitable for comparison analysis at different spatial scales as well as continuously tracking the dynamic changes. Therefore, this research can be a good practice of applying the spatiotemporal philosophy to urban geographical problems.

Sustainable urban parks provide social and economical benefits to the residents and contribute to the urban ecosystem health. Municipalities are responsible for development and management of urban parks and the goal of this study was to better understand if, and why, the municipalities in the Greater Toronto Area (GTA) have utilized sustainable development strategies in the planning, design, construction and management for their new park projects. A qualitative study utilizing an in-depth interview format was created based on the principles of sustainable development compiled from the Sustainable Sites Initiative. A sample of four municipalities in the GTA was selected based on population and development growth and the park authorities were contacted. The results indicated few sustainable initiatives implemented in the design and management stages of park development. Understanding the constraints against these suggest that there may be potential to increase the sustainability of urban parks. / The Goal of this thesis was to explore if, and why, the municipalities in the Greater Toronto Area (GTA) have or have not adopted sustainable development strategies in planning, design, construction and management of their new parks.

The pursuit of urban sustainability is considered central to sustainable development and is a key objective of the global Sustainable Development Goals (2015) and the New Urban Agenda (2016). This thesis aims to contribute to debates on urban sustainability by providing insights as to the role of actors participating in processes of governing for urban sustainability, with particular focus on the municipal organisation. The thesis employs an interdisciplinary approach to illustrate divergent approaches to governing for urban sustainability, with reference to empirical studies of strategic planning processes in municipalities in selected North-western European countries – Sweden, Switzerland and The Netherlands. These studies address themes including climate change, sustainable transport and multi-level governance. The thesis provides a broad overview of theoretical discussions related to governing, strategy and planning, the role of actors in governing for urban sustainability, and the particular importance of climate change as a challenge for urban sustainability. A number of research gaps are identified and addressed in two research questions, focusing on the organisation and practice of processes of governing for urban sustainability, and the factors influencing actors participating in such processes. The thesis responds to these research questions with reference to five appended papers, which illustrate different dimensions of governing for urban sustainability. The first paper concerns the organisation of processes to develop energy and climate strategies in Swedish municipalities, and the second paper highlights the experiences of actors participating in such processes. The third paper presents results from a survey illustrating the expectations of stakeholders active in governing transport in the city of Norrköping, Sweden. In the fourth paper, the development and implementation of policies aiming for sustainable transport and urban sustainability in Basel, Switzerland, are discussed. In the final paper, cooperation through transnational municipal networks is explored with reference to the World Ports Climate Declaration, an initiative of the city of Rotterdam. The thesis confirms the presence of five factors – capacity, mandate, resources, scope and will – that shape the “strategy space” of actors and play an important role in conditioning the form and content of processes of governing for urban sustainability. The thesis suggests that the ways in which a municipal organisation perceive and mobilise the five factors will strongly determine the extent of its sustainability strategy space. In sum, municipal organisations and other actors participating in processes of governing for urban sustainability need to mobilise the five factors and expand their strategy space, in order to achieve vertical and horizontal alignment of strategic objectives and facilitate implementation that delivers transformative change.

Urban areas are facing huge environmental challenges due to an increase in the population from 50% to 70% until 2050. The European Commission promotes the European Green Capital Award to give European cities motivation to facilitate a change towards urban sustainable development in medium-sized cities, where the city Umeå in north Sweden is applying for the third time. The aim of this study is to see whether the award is a useful tool for the environmental work in Umeå and if there are controversies among the stakeholders of the city. Interviews have been conducted where interviewees from several areas, both pro and against the award, have been interviewed. It is shown that the award has several impacts where most of them are beneficial for the environmental work in the city, such as structuring the environmental work. The main challenge with the award is a communication failure between the project group and other stakeholders of the city. The conclusion is that the award in itself seem to be good for the environmental work in Umeå but that the communication between the project group and the citizens needs to be improved.

Research Doctorate - Doctor of Philosophy (PhD) / This thesis presents the results of an application of grounded theory research methodology to an area of study not previously tested by this technique. The allocation of land to urban growth impacts on both urban areas and the environment. A group of twenty leading practitioners in the field was interviewed and asked, in a set of structured questions, about their roles, the most important issues confronting them from ongoing urban development of Greenfield sites, how they saw the interaction between the current system of regulation and these issues, and changes they considered to be required. Applying grounded theory identified that the issues which concerned the practitioners fall into the following groupings: urban and environmental sustainability, the inadequate integration of these components yet the need to recognise their interaction, and the decision making process in terms of who is making decisions and how and when decisions are made about the allocation of land for urban growth. The current system is based primarily on the objective of resolving conflicts concerning land use. It was expected that the data obtained during the interviews may confirm the current orthodoxy. Unexpectedly, the data revealed not only a commonality of views but also a set of recommendations which could form the basis of a management framework to achieve greater environmental and urban sustainability. The interviewees pointed to proposals for urban growth in coastal NSW where a number of the recommendations have already been embraced by the NSW Government.

The motivation for this research is a perceived gap in knowledge regarding the complex relationships between the physical form of the urban environment; its environmental performance as expressed through stocks and flows of materials and energy (urban metabolism); and its experienced physical and psychological qualities (urban ambience). The objective is to develop a practical methodological structure which, through investigating the relationships between these domains, may help inform the evaluation, design and development of more sustainable human settlements. One expression of this apparent knowledge gap is the ambiguity around the classification of urban form and identification of a suitable taxonomic framework to support analysis. Urban morphological research and practice is critically reviewed to derive a rigorous definition of the 'urban structural unit' (USU) to facilitate the subdivision and description of urban form across spatial scales. Application of this construct to a study site in Sydney, Australia provides the basis for subsequent exploration. Investigation of theoretical and applied perspectives on urban ecology, metabolism and design enables distillation of a utilitarian set of structural, functional and ambience properties of the USU. A variety of quantitative methods pertinent to evaluation of these properties is systematically examined to derive a streamlined analytical methodology, integrating hemispherical image analysis, space syntax, isovist and material accounting methods within the USU framework. The efficacy of this methodological 'toolkit' is tested in the final, empirical stage of the research, focussing mainly on the campus of the University of New South Wales. Determination of a range of material, microclimatic, ecosystemic, fractal, syntactic and isovist metrics provides a preliminary quantitative description of the campus USU in terms of its interrelated metabolic and ambience properties. This is further explained and interpreted through multivariate statistical analysis. The results suggest that the USU represents a robust framework for urban evaluation, and application of a relatively parsimonious suite of analytical methods enables a useful initial examination of the relations between significant aspects of urban form, metabolism and ambience. The outcomes of such an evaluation can directly inform built environment practice from a sustainability perspective, and also highlight areas for more detailed investigation.

And its premise is the adjective sustainable rely on systems theory, which makes it a mechanistic, consistent and widespread system in practice. So, this thesis sought first understand the process of sustainable development, through the complexity of their spatial and temporal contextualization, global and local, which have characterized him as the new neoliberal mode of regulation, to their flexible accumulation. Inserted in this context, the city of Maringá, in Paraná State (Brazil), is also produced by development projects that aim to make it more competitive in the multiscale markets, to attract capitals. As proposed, on the one hand, the theoretical project sustainability of Maringá comes from the principles of adjusting the standard of production-consumption and legitimation of social rhythms in the appropriation of natural resources, according to the fundamentals of sustainable conception and maringaense production of urban space. And on the other hand, the practical project comes from the... (Complete abstract click electronic access below)

While cities across the world are adopting urban sustainability plans and pursuing ‘sustainable development,’ the question of how these urban sustainability plans have made our cities indeed sustainable is a subject of debate. Some scholars are skeptical about whether urban sustainability planning challenges or reproduces existing power imbalance in the growth politics in cities. Given the current trend that the concept of sustainability has become embedded in our culture, little is known about the urban politics around urban sustainability plans and their effectiveness in promoting balanced sustainability in Asian cities. Using a case study of Seoul through in-depth interviews, this study examines the urban politics around the decision-making process and the implementation of sustainability plans in Seoul. As a rare case of recent rapid socio-economic transformations with the legacy of a developmental state, Korea serves as an example of how these transformations are likely to have for the urban politics of sustainability policies in other Asian countries. As conclusions, developmental states like Korea with a centralized governance system tend to use a “sustainability fix” that is heavily focused on ‘pro-growth’ development. With globalization, privatization, and democratization, the growth machine politics around urban sustainability planning in Korea is similar to that observed in the Western context. However, in Seoul, the growth machine is heavily influenced by the federal government and Mayoral leadership. This is because of the embedded legacy of the developmental state. In addition, with increased democratization and a growing role of civic groups in urban politics, we see a move towards “just sustainability” in urban sustainability planning in Korea. / Geography
