Sustainability, livability and quality of life have become widely and in-depth discussed issues in the literature of urban zlanning and design. This study primarily aims to investigate the concept of walkability as a part of the literature on livability. To draw a wider theoretical framework for this study, it first seeks to answer the questions of what the terms of &lsquo / livability&rsquo / and &lsquo / quality of life&rsquo / mean, and what components they constitute. Then, it focuses on the concept of &lsquo / walkability&rsquo / as one of the major components of these terms and as a measurable notion in urban design. Thus, this research seeks to define the notion of &lsquo / walkability&rsquo / and to identify a set of measures of walkability in public spaces to be used for the assessment of the &lsquo / walkability capacity&rsquo / of urban space. It should be noted that this research particularly tries to use the indicators of walkability which can directly impact on the design quality of urban space. Third, this research focuses on Mersin historic city center which has been in the process of deterioration for a while due to various current urban policies and strategies. As the case studies, it examines Uray and Atat&uuml / rk Streets which constitute the major thoroughfares of the historic city center by using the set of walkability measures. It investigates the walkability quality of four different character zones of Uray and Atat&uuml / rk Streets, and identifies their walkability capacities, problems and potentials. Finally, it suggests the policy and practical solutions on the design of these public spaces that will not only improve the walkability capacity of these streets, but also be helpful for the revitalization of the historic city center.

Earth is becoming more urban. As the human population continues the current trend of migrating towards urbanized regions, the pressures to develop urban greenspaces will inevitably increase. Greenspaces play a critical role in urban livability for both human and non-human beings. This research examines the creation and management of the Rouge Park (Ontario, Canada), which is a large greenspace approximately 46 km2 located in the eastern portion of the Greater Toronto Area. The output of this research consists of three parts. The first provides an identification of the relevant actors, and a detailed chronology of the social and political events that led to the establishment of the Rouge Park. The second section explores the competing narratives of science, conservation, and development that were fundamental in shaping the protected area that we see today. The final section examines the governance and administration of the Rouge Park, and investigates the activities and involvement of civil society actors working in its day-to-day management. Using qualitative methods, I demonstrate that science and scientific expertise can be powerful tools of legitimization for civil society actors. In particular, I examine the benefits and pitfalls of placing ecologically-based rationalizations at the forefront of conservation policy deliberations. Furthermore, I show that despite shortcomings in the governance structure of the park, the current arrangement has provided civil society actors with increased opportunities to shape their community. My results show that a locally grounded nature conservation movement can serve as a powerful motivating force for citizens to enact long-term environmental planning initiatives.

Baltimore fait partie des grandes métropoles américaines qui se sont lancées dans le cercle vertueux du développement durable. Traditionnellement acquise aux votes démocrates, constituée d’une majorité d’Afro-Américains appartenant aux classes sociales défavorisées, et portant les profonds stigmates de la crise industrielle et des récessions économiques successives, la ville offre un terreau favorable aux expériences de gestion urbaine intégrant la notion de durabilité. Bien plus, tant du point de vue des caractéristiques économiques et démographiques que de celui de l’héritage marqué de la ségrégation, c’est la dimension sociale du développement durable et la justice environnementale qui sont en jeu. Depuis 2000, la municipalité a initié deux grands projets intégrant le développement durable dans ses dimensions de « sustainability », « livability » et « smart growth », pouvant être regroupées sous l’appellation de « green politics ». L’essentiel de ses efforts porte sur la revitalisation de deux ghettos du centre-ville tombés en complète déshérence, East Baltimore et West Baltimore. Nous concentrerons notre réflexion sur deux exemples précis de « green politics » (la réhabilitation d’une partie du ghetto d’East Baltimore avec le Grand Piano ; la Red Line, ligne de train qui doit relier les deux ghettos et des zones de friches industrielles au quartier des affaires). À partir de ces exemples, nous étudierons les modes de gouvernance mis en place et le rôle joué par les différents acteurs qui y participent (« anchor institutions », grandes fondations, acteurs publics et associations de quartier). Nous nous interrogerons sur l’émergence de formes inédites de citoyenneté façonnées par ces nouveaux modes de participation à l’aménagement urbain durable. Il s’agira de comprendre si le développement durable est conçu au service des habitants du ghetto afin de lutter contre la pauvreté et les injustices sociales et environnementales, ou si, au contraire, la racialisation de ce concept favorise la gentrification, crée de nouvelles formes de ségrégation et aboutit à la fin programmée des ghettos. / Baltimore is part of the big American metropolises committed in a race for sustainable development. Traditionally a democratic stronghold, with a majority of city dwellers who are poor Afro-Americans, and harshly battered by the industrial crisis and the economic recession, Baltimore City is the perfect laboratory for urban planning projects experimenting sustainable development. Furthermore, with regard to its economic and demographic characteristics and the importance of segregation in the city, the social dimension of sustainable development and the issue of environmental justice are at stake. Since 2000, the Mayor and the City Council initiated two ambitious projects integrating the various aspects of sustainable development (« sustainability », « livability » and « smart growth »), which are all belonging to « green politics ». These efforts are focused on East Baltimore and West Baltimore, two huge ghettos surrounding the financial district in the downtown area. The core of our analysis concerns two projects of green politics (the rehabilitation of a part of the East Baltimore ghetto through the Grand Piano; the Red Line, a train connecting the ghettos, some industrial wastelands and the Central Business District). Through these examples, we will put under study the types of urban governance and urban regimes at work, and the role played by the different stakeholders (« anchor institutions », philanthropic foundations, public actors and neighborhood associations). New forms of citizenship may appear with unheard modes of participation to sustainable urban planning. Sustainable development may be an opportunity to improve the living conditions in the ghetto and fight against poverty and social and environmental injustices. The seamy side of the story may be a racialization of sustainable development nourishing gentrification, creating new forms of segregation and bringing about the death of the ghettos.

What makes a community sustainable? Is it the effective management of local environmental resources? Or meeting the social, economic and health needs of its population? For the five UBC researchers in the following pages, the answer is unequivocally both. From tackling water scarcity to environmental health and planning, these researchers are individually working to ensure local communities are equipped with the necessary knowledge to remain sustainable for generations to come.

This thesis studies why car-initiatives are implemented and how political visions is intertwined in this process. These topics are further explored by looking at how certain critical groups are impacted by car-free initiatives and how they can affect polarization. We use a holistic multiple case comparing Oslo’s Car-free Livability Programme with Living Stockholm. This analysis is structured with our adapted version of the multi-level perspective framework, which emphasizes social components to a greater extent than the original framework. The results show that climate concerns, a common reason to implement car-free initiatives is superseded by softer values such as an increased appreciation of urban areas. Prohibiting cars from city centers has limited short term climate effects. Instead, the value of car-free initiatives is achieved when the urban environment is improved. Additionally, an important and often overlooked result is that car-free initiatives may help change the publics’ perception of the necessity of cars. Furthermore, the political vision behind the project is interlinked with how car-free initiatives are recognized in the public. A strong political vision backed by heavy rhetoric increases the societal impact of the project, as exemplified by Oslo. The project can potentially alter the general perception of the necessity of the car long-term with such an approach but is also exposed to the public’s glare. However, if the project only focuses on a specific area of the city, it may contribute towards polarization and a feeling of discontent within society. In comparison, by implementing an agile approach without a clear political vision as Stockholm did, the project becomes more flexible and reduces unintended consequences. but also has less influence on a national or international level. Furthermore, failing to cater for the needs of critical groups, such as people with disabilities and craftsmen, often results in difficulties and may become a major source of concern within the project. However, these issues can often be identified with improved communication and reduced with small means. To conclude, the emergence of car-free initiatives is a budding trend not only in Scandinavian cities, but around the world. Fueled by concerns about the climate and an urge for citizens to reclaim urban space, car-free initiatives will become more common. Therefore, to implement successful car-free initiatives, it is vital for institutional actors to keep in mind the key points proposed in this thesis, in order to create successful, vibrant cities in the future. / Den här uppsatsen studerar varför bilfria initiativ implementeras och hur den politiska visionen påverkar utformningen. Vi analyserar även hur vissa grupper kan beröras negativt av bilfria initiativ och hur det kan påverka polariseringen i en stad. Uppsatsen använder sig av en holistisk multipel case studie, och jämför de båda huvudstadsinitiativen Bilfritt Byliv i Oslo och Levande Stockholm. Analysen är strukturerad med hjälp av vår anpassade version av multi-level perspective ramverket, som lägger större vikt vid sociala aspekter än ursprungsmodellen. Resultaten visar att klimatförbättringar, en vanlig anledning till att implementera bilfria initiativ, inte är den främsta samhällsnyttan. Andra aspekter som ofta förbises, exempelvis en ökad uppskattning av urbana miljöer, tycks vara viktigare. Att förbjuda bilar har begränsad direkt klimatnytta, utan det är vad stadsytan används till i stället som skapar olika mervärden. En ökad insikt om detta skulle sannolikt kunna göra initiativ för att minska privat bilismen mer ändamålsenliga. Vidare kan bilfria initiativ påverka allmänhetens uppfattning om bilens nödvändighet, vilket är en fråga som inte fångas upp av existerande litteratur. Bilfria initiativs utformning, och allmänhetens uppfattning av det påverkas till stor del av projektets politiska vision. En tydlig vision och kommunikation kan skapa en bred allmän medvetenhet om projektet, som i Oslos fall. Initiativetkan på så sätt skapa en betydande förändring i samhället, men exponeras därigenom även för kritik. Om projektet enbart omfattar särskilda stadsområden finns det en risk för att projektet ökar polariseringen och upplevelsen av utanförskap i staden. Om man i stället använder en mer agil approach utan en tydlig politisk vision, likt Stockholm, blir projektet mer flexibelt och minskar risken för negativa konsekvenser. Men man går därmed till stor del miste om möjligheten att påverka attityder på nationell, eller internationell nivå. Att inte ta hänsyn till grupper med särskilda behov, som äldre eller personer med funktionsnedsättning, resulterar i svårigheter såväl för dessa gruppersom för projektet. Med en intressent analys i förväg och en tydlig kommunikation kan många problem åtgärdas med små medel. Sammanfattningsvis har vi funnit att bilfria initiativ är en trend som växer sig allt starkare runt om i världen, pådriven av en ökad klimatmedvetenhet och en vilja bland stadens invånare att återta urbana miljöer från bilar. Med studien presenterar vi viktiga aspekter för att möjliggöra en effektiv implementering av bilfria initiativ och skapa framtidens levande städer.
