Grönska som sköld mot klimatförändringar : En framställd grundläggande grönytefaktor-modell för att stärka städers resiliens

Bergh, Linnea, Bergkvist, Johanna January 2020 (has links)
Denna rapport tar avstamp i forskning om resiliens och ekosystemtjänster. Vidare syftar studien till att framställa en grundläggande grönytefaktor-modell för att främja resiliens genom att undersöka vilka grönytefaktorer som ska finnas med. För att besvara frågeställningen: Vilka grönytefaktorer ska finnas med i den grundläggande modellen för att främja högre resiliens i staden?tillämpas de kvalitativa metoderna innehållsanalys och fokusgrupp. Innehållsanalysen innefattar en tematisk analys över Stockholm, Göteborg och Malmös befintliga grönytefaktor-modeller och fokusgruppen består av tjänstemän från Norrköpings kommun. Det empiriska materialet kopplas till det teoretiska ramverket om resiliens och mynnar ut i en framställd grundläggande grönytefaktor-modell som utgår från de tre perspektiven: sociala värden, biologisk mångfald och klimatanpassning. De grönytefaktorer som resultatet av rapporten visat bidrar till högre resiliens och som integrerats i den framtagna grundläggande modellen är: genomsläppliga ytor, gröna markytor, träd, nya träd, bevarade träd, buskar, gröna tak, gröna väggar, dammar, vattendrag och diversitet i grönska. / This report aims to examine what a fundamental biotope area factor (BAF) should contain to support resilience in urban areas based on scientifical studies on resilience and ecosystem services. To be able to address this issue the qualitative methods content analysis and focus group have been used. The content analysis consists of three existing municipal BAF-models from Stockholm, Gothenburg and Malmö. The result of the focus group is based on the experience and knowledge of five officials at the municipality of Norrköping planning office. This study’s empirical material is linked to the theoretical framework of resilience and is the foundation for the BAF-model in the report which is based on the three perspectives: social values, biodiversity and climatization. The factors that this report has found increase resilience in urban areas are: permeable areas, green ground areas, trees, new trees, preserved trees, shrubbery, green roofs and walls, ponds, water courses and diversity in greenery.

Peri-urbanization and land management sustainability in Peruvian cities / Péri-urbanisation et gestion durable du territoire dans les villes péruviennes

Moschella Miloslavich, Paola 21 September 2018 (has links)
La croissance urbaine incontrôlée est liée à plusieurs problèmes socio-environnementaux dans les pays en développement comme le Pérou. Afin de comprendre l'expansion urbaine dans les zones non aménageables, la recherche combine trois dimensions de l'analyse : l'analyse spatiale, l'analyse du comportement social et l'évaluation de la gestion urbaine et de l'aménagement du territoire. L'étude se concentre sur trois cas péruviens : une oasis de brouillard saisonnier dans la ville aride de Lima, les terres agricoles de première qualité de la vallée de Cajamarca et les zones humides de la petite ville de Huamachuco. L'expansion urbaine dans les études de cas est principalement informelle et désorganisée; à cause de sérieuses déficiences dans la gestion publique locale, la planification routière et la culture de l'informalité. Cependant, certaines organisations communautaires et certains leaders sociaux contribuent à une utilisation plus durable du territoire. / Uncontrolled urban expansion is related to several socio-environmental problems in developing countries like Peru. In order to understand the urban expansion in non-developable areas, the research combines three dimensions of analysis: spatial analysis, social behavior analysis, and the evaluation of urban management and spatial planning. The study focuses on three Peruvian cases: a seasonal fog-oasis in the arid city of Lima, the prime farmlands in Cajamarca valley, and the wetlands of the small city of Huamachuco. Urban expansion in the case studies is predominantly informal and disorganized as a consequence of serious deficiencies in local public management, road planning, and the culture of informality. However, some communal organizations and social leaders contribute to a more sustainable land-use.

Barns perspektiv på framtidens resor med autonom buss / Children’s perspective on future travels by autonomous bus

Larsson, Kristina January 2021 (has links)
Barns mobilitet och möjlighet att på egen hand ta sig runt i staden har minskat och begränsas idag i stor utsträckning av otrygga trafiksituationer. I och med sin begränsade oberoende mobilitet exkluderas barn från stadsrummet och dess faciliteter. Oberoende mobilitet kan relateras till flera dimensioner av barns sociala, fysiska, psykiska och kognitiva välmående. Syftet med studien är att undersöka om och på vilket sätt autonoma bussar kan bidra till barns oberoende mobilitet och med hjälp av barns upplevelser och erfarenheter bidra med insikter i detta inför införandet av autonoma bussar i städer och kollektivtrafiksystem. För att göra det besvaras frågeställningarna “Hur kan autonoma bussar i transportsystemet bidra till barns oberoende mobilitet?” och “Vilka förutsättningar är nödvändiga för att autonoma bussar ska bidra till barns oberoende mobilitet?”. Undersökningen utgår från ett fall av införande av autonoma bussar i stadsmiljö och för att besvara frågeställningarna genomfördes med elever på en grundskola fokusgrupper med syfte att inhämta deltagarnas upplevelser och erfarenheter. Resultatet tyder på att införandet av autonoma bussar i ett urbant område kan bidra till barns oberoende mobilitet på flera sätt och att bussarna har vissa egenskaper som gör att de kan anpassas till barns förutsättningar. Insikter från studien kan bidra till en förståelse för hur, från barns eget perspektiv, oberoende mobilitet kan gynnas av autonoma bussar i kollektivtrafiken, samt hur tjänsten behöver utvecklas för att anpassas till denna användargrupp när autonoma bussar i större utsträckning ska implementeras i staden. / Children's mobility and the opportunity to get around the city on their own has decreased and is today limited to a large extent by unsafe traffic situations. Due to their limited independent mobility, children are excluded from the urban space and its facilities. Independent mobility can be related to several dimensions of children's social, physical, mental and cognitive wellbeing. The purpose of the study is to investigate if and in what way autonomous buses can contribute to children's independent mobility and, using children's experiences, provide insights into this before the introduction of autonomous buses in cities and public transport systems. To do so, the two research questions "How can autonomous buses in the transport system contribute to children's independent mobility?"and "What prerequisites are necessary for autonomous buses to contribute to children's independent mobility?" are answered. The survey is based on a case of introduction of autonomous buses in urban environments and to answer the questions three focus groups with students in a primary school were conducted with the aim of gaining the participants' experiences. The results indicate that the introduction of autonomous buses in an urban area can contribute to children's independent mobility in several ways and that the buses have certain characteristics that enable them to be adapted to children's conditions. Insights from the study can contribute to an understanding of in what way, from children's own perspective, independent mobility can benefit from autonomous buses in public transport, and how the service needs to be developed to adapt to this user group when autonomous buses are to be implemented to a greater extent in the city.

Towards an ecological approach for sustainable urban planning: the case of the Brussels-Capital Region

Stessens, Philip 19 June 2019 (has links) (PDF)
In the last decades the population living in cities has substantially increased. According to the United Nations, by 2050 two thirds of the world population will be living in urban areas. Demographic pressure, through influx of residents or internal growth results in expansion and densification of urban areas and goes hand in hand with increased imperviousness, putting pressure on the provision of urban green. Urban green offers a range of direct and indirect benefits to the urban ecosystem. Green in the city reduces rainwater runoff and flooding risk while improving water quality; it improves air quality, provides natural cooling and contributes to reducing the urban heat island effect. Being the main source of contact with nature, urban green has also been shown to contribute to the physical and psychological wellbeing of urban citizens. The environmental concern for urban nature and re-naturing of cities are thus at the heart of developing more «ecological approaches to sustainable urban design and planning». In the framework of this research, it implies: understanding the (spatial) distribution of green space in relation to the built-up area of the city at different scale levels – the benefits they provide, their quality and proximity for urban residents – and; how to develop diagnostic, analytical and projective capabilities aimed at improving their (urban green) provision to address a host of sustainability challenges related to climate change, demographic growth and densification of the urban area. The research focuses on the development of evidence-based frameworks for planning that incorporate citizens’ needs and that are built on an interdisciplinary foundation. With this scope and focus, this study contributes to the development of a more ecological framework for sustainable urban design and planning aimed at integrating nature in the city more effectively and in an evidence-based way. The first part of the research focuses on the development of a spatially explicit tool for green space quality and proximity assessment reflecting user’s perception. Application of the model in the Brussels context reveals that user’s perception of qualities of urban green spaces such as naturalness and spaciousness can be linked to green space characteristics as described by available GIS-based data. As such GIS-based modelling allows for an extrapolation of questionnaire-based quality assessments for a selection of parks to other public green spaces. Analysis of the proximity of urban green spaces based on user’s perception shows spatial inequalities in green space provision, with less than 50% of Brussels’ citizens having good access to small (residential and play green) and to large green spaces (city and metropolitan green). By coupling multi-scale proximity assessment with quality assessment of green spaces, it is demonstrated that nearly two third of the Brussels population has no access to high quality public green spaces. Through collaborative research by design workshops involving different stakeholders, indicators produced by the quality-proximity model are used to indicate and tackle problem areas. Three alternative scenarios for public green space development are defined. The scenario analysis demonstrates that actions to provide low-income neighborhoods with a good accessibility to public green spaces will require creative solutions, dealing with complex property and management issues, and levels of investment that go well beyond the cost of regular green space development. The second part of the study presents a GIS- and design-based approach to assess potential land cover change for the Brussels-Capital Region anticipating expected population growth. The methodology proposed can be used to assess the impact of spatial policies and the implementation of building codes on future urban land cover. By studying the everyday processes for parcel infill and densification, and by defining a densification process based on the principles of sustainable urban design (e.g. walkable and high-density urban areas near mobility hubs, compact building typologies, preserving valuable natural areas, creative approaches to increasing the provision of urban green (green roofs, bioswales, etc.) space for water and floodscapes, etc.), two land use evolution scenarios are formulated; a business-as-usual and a sustainable scenario. One of the main conclusions of the case study on the Brussels-Capital Region is that densification can be deployed as a vehicle for positive land cover change and greening of the city. / Doctorat en Art de bâtir et urbanisme (Architecture) / info:eu-repo/semantics/nonPublished

Grön Stadsby : ett förslag på en hållbar stadsutveckling / Green Urban Village : a proposal for a sustainable urban development

Runesson, Axel, Alwahhab, Ahmed January 2021 (has links)
Studien handlar om hållbar utveckling med utgångspunkt i stadsutveckling där byggandet idag står för en stor del av klimatförändringarna vilket är något som behöver åtgärdas enligt Agenda 2030. Att bygga hållbart är en förutsättning för att minimera klimatförändringarna.Grön Stadsby är ett förslag i en motion från Centerpartiet i Växjö kommun för en hållbar stadsutveckling med de globala målen Agenda 2030 och Växjös hållbarhetsprogram som utgångspunkt. Syftet med studien var att göra en fördjupning av den Gröna Stadsbyns kriterier samt att ta fram ett förslag på en gestaltning i from av en illustrationsplan. Målet var att få en bebyggelse med en så låg klimatpåverkan som möjligt som även uppfyller kriterierna för en Grön Stadsby i motionen.Insamling av data skedde genom studier av artiklar, avhandlingar, rapporter, dokument, GIS-analyser av kartor samt intervjuer med sakkunniga personer inom området. Resultatet av insamlingen visar att en viktig förutsättning för en Grön Stadsby är att den har en låg klimatpåverkan och i övrigt kan uppfylla de globala målen för en hållbar stadsutveckling. Det framtagna förslaget på en Grön stadsby visar att en sådan mycket väl kan byggas och utvecklas i Jonsboda, en plats i Växjö kommun där kommunen själv föreslår att en Grön Stadsby skulle kunna förläggas. / The study is about sustainable development based on urban development where construction today accounts for a large part of climate change, which is something that needs to be addressed according to Agenda 2030. Building sustainable is a prerequisite for mitigating climate change.Green Urban Village is a proposal in a motion from the Center Party in Växjö Municipality for a sustainable urban development with the global goals Agenda 2030 and the sustainability program of Växjö as a starting point. The purpose of this study was to make an in-depth study of the Green Urban Village criteria and a proposal for a design in devotion of an illustration plan. The goal was to get a settlement with as low a climate impact as possible, which also meets the criteria for a Green Urban Village.The collection of data consisted of a study of articles, dissertations, reports, documents, GIS analyzes of maps and interviews with experts in the area. The results of the study show that a Green Urban Village a low climate impact is vital in order to meet the global goals for sustainable urban development. The conclusion that can be drawn from the study is that the proposed concept of Green Urban Village could contribute to a sustainable development of urban areas.

Externa och halvexterna handelsetableringar : En kvalitativ analys av attityder och drivkrafter för planering och utveckling av externhandel i Gävleborgs län

Blom, Lisa, Fridh, Johanna January 2020 (has links)
Det svenska transportsystemet är i dagsläget till stor del fossilberoende och efterfrågan på transporter förväntas öka det närmaste decennierna. En ökad efterfrågan på transporter genererar i sin tur ökade utsläpp, vilket medför negativa effekter på människors hälsa men även på miljön. För att nå uppsatta klimatmål måste trenden om ständigt ökade trafikvolymer brytas. Samhällsplanering och beteendeförändringar av det mer kraftfulla slaget är nödvändigt för att kunna skapa ett hållbart transportsystem. All utbyggnad av transportinfrastrukturen innebär långsiktiga konsekvenser, dels på grund av den omfattande påverkan det har på städers och regioners struktur men också för att de leder till ett ökat bilresande och därmed större klimatpåverkan. Drivkraften för externa handelsetableringar är stark, och det finns fortfarande många förespråkare som menar att dessa etableringar behövs för att utöka kommuners konkurrenskraft. När externa handelsområden och köpcentrum etableras ökar det totala trafikarbetet med personbil, vilket har en direkt proportionell ökning av koldioxidutsläpp. I Sverige finns inga politiska krav på hur planering av externa och halvexterna handelsetableringar ska utformas, och kommunerna är inte heller skyldiga att upprätta några policys kring dessa etableringar. Detta examensarbete har genom kvalitativa intervjuer med nyckelpersoner i Gävleborgs län undersökt vilka drivkrafter och attityder som finns hos kommunerna vad gäller utveckling och planering av externa och halvexterna handelsetableringar. Ämnet har analyserats utifrån perspektiven tillgänglighet och hållbar utveckling, med stöd från det regionala hållbarhetsmålet om en fossilfri fordonsflotta år 2030, samt den svenska klimatlagen. Det som framkommit under intervjuerna är att det inte finns någon direkt drivkraft hos kommunerna att etablera nya externa handelsområden, men att det finns en vilja att fortsätta utveckla de redan existerande handelsområdena då dessa är viktiga för den lokala tillväxten. I Gävleborgs län prioriteras personbilen och är det vanligaste transportmedlet till länets externa och halvexterna handelsområden. Kommunerna arbetar med att förbättra tillgängligheten med kollektivtrafik, cykel och gång, men trots detta finns uppenbara brister och en medvetenhet om svårigheterna att få hållbara resemedel att bli de dominerande transportsätten till dessa områden. Mer kraftfulla metoder och åtgärder inom samhällsplanering och beteendeförändringar är nödvändigt för att kunna skapa ett hållbart transportsystem. Det kan uppnås genom att kombinera olika styrmedel och att förbättra samverkan inom såväl kommunerna som regionen i helhet. / The current Swedish transportation system is depending on fossil fuels and the demand for transportation is expected to increase in the coming decades. This will lead to increased emissions of greenhouse gases and other airborne pollutants, which have negative impacts both on human health and the environment. In order to achieve the national climate targets, the trend of constantly increasing traffic volumes must be slowed down. In order to create a sustainable transport system, radical changes in both community planning and behavioral changes are going to be necessary. All expansion of the transport infrastructure has long- term consequences, partly because of its extensive impact on the structure of cities and regions, but also because they can cause increased car travel and generate greater climate impacts. External trade agreements and the strive towards economic growth has a strong influence on traffic planning in the Swedish municipalities. When suburban retail districts and shopping centers are established, the total amount car traffic increases, which leads to increased carbon dioxide emissions. In Sweden, there are no political rules or guidelines on how external trade establishments should be planned, nor are the municipalities obliged to establish any such policies. Through a series of qualitative interviews with people in position of policy making in Gävleborg County, the present thesis investigated the driving forces and attitudes that exist in the municipalities regarding the development and planning of external establishments. The topic has been analyzed from the perspective of accessibility and sustainable development, supported by the regional sustainability goal of a fossil-free vehicle fleet in 2030, and the Swedish climate law. What emerged during the interviews is that there is no direct impetus for the municipalities to establish new external trade areas, but that there is a willingness to continue to develop the already existing ones, as they are deemed important for local growth. In the regional traffic planning, the passenger car is given priority, since it is the most commonly used means of transportation to and from the county’s suburban shopping districts. The municipalities are working to improve accessibility by public transport, bicycle and walking, but there is an awareness of the difficulties in making sustainable forms of travel the dominant transportation to these areas. More powerful methods and measures in community planning and behavior change are necessary to create a sustainable transport system. This can be achieved by combining different instruments and improving collaboration within both the municipalities and the region.

Social sustainability in Swedish urban development - what does it mean? : A casestudy of three Citylab Action pilot projects / Social hållbarhet i svensk stadsutveckling - vad innebär det? : En fallstudie över tre Citylab Action-pilotprojekt

Liljefors, Pontus January 2016 (has links)
Cities around the world are facing challenges of rapid population growth, social inequality, environmental degradation and climate change. Within the realm of planning and policy, one answer to these issues has been the invention of certification systems to support the transition to a sustainable urban development. In the last ten years a number of certification systems for sustainable urban development on neighbourhood level have been developed, such as BREEAM Communities and LEED Neighborhood Development. Though an important contribution for a systematic way to treat sustainability in urban development, such systems have been criticised in a number of criteria, among which an important deficiency is their lack of factors for social sustainability. A new Swedish certification system for neighbourhood level, Citylab Action, is since January 2016 being tested in a pilot round with twelve Swedish urban development projects. The aim of this study was therefore to investigate how three of the pilot projects worked with social sustainability and within which areas the Citylab Action Guide best could be developed to support socially sustainable urban development. The following research questions were formulated: What is a relevant understanding of social sustainability for contemporary urban development drawing on the academic literature? How do the selected Citylab Action projects understand and work with social sustainability? What are projects’ key challenges for creating socially sustainable neighbourhoods? What are the projects’ experiences with Citylab Action in relation to their work with social sustainability? The thesis had a critical approach and took ground in a literature study, which rendered an analytical framework and the normative standpoint that social sustainability needs to be concerned with increasing social justice. Täby Park, DrottningH and Masthuggskajen were selected as cases, and studies involved interviews with two civil servants from each project and analysis of planning documents related to the projects’ work with social sustainability. An analysis of the empirical material was carried out underpinned by the analytical framework, which contained the questions: How is social sustainability (implicitly) defined and operationalised? How is the project oriented in regards to the dualism of development and maintenance? Who is considered in the development of the district? Results showed theoretical understanding of social sustainability, as well as operational work, were very different between projects. Synthesis suggests a key challenge for the projects’ work with social sustainability concerns the tendency of marginalising people with less purchasing power. For the development of the Citylab Action Guide to better support socially sustainable urban development, four proposals are given. The Guide should include: more aspects for how to work with existing inhabitants, more distinct aims for projects to execute a comprehensive analysis of the effects on segregation patterns, more attention to the creation of affordable apartments and socially mixed housing, and aims for considering the seven discrimination grounds and socio-economic status in the outcomes of planning. / Städer världen över står idag inför svåra utmaningar såsom befolkningsökning, växande klyftor ökande resursanvändning och klimatförändringar. Ett svar på dessa utmaningar har inom policy och planering varit utvecklingen av certifieringssystem för att stödja övergången till en hållbar stadsutveckling. De senaste tio åren har ett antal certifieringssystem för hållbar stadsutveckling på stadsdelsnivå utvecklats, såsom BREEAM Communities och LEED Neighborhood Development. Dessa verktyg har utgjort ett viktigt steg framåt för ett systematiskt arbete med hållbarhet i stadsutveckling, men också kritiserats för att vara otillräckliga på flera punkter, däribland i sin behandling av social hållbarhet. Ett nytt svenskt certifieringssystem för stadsdelsnivå, Citylab Action, testas sedan januari 2016 i en pilotrunda av tolv svenska stadsutvecklingsprojekt. Föreliggande uppsats avsåg att undersöka hur tre av dessa pilotprojekt har arbetat med social hållbarhet, samt inom vilka områden Citylab Action-guiden kan utvecklas för att på bästa sätt stödja socialt hållbar stadsutveckling. Följande forskningsfrågor formulerades: Vad är en relevant förståelse av social hållbarhet för dagens stadsutveckling utifrån den akademiska litteraturen? Hur förstår och arbetar de utvalda Citylab Action-projekten med social hållbarhet? Vad är projektens största utmaningar för att skapa socialt hållbara stadsdelar? Vad är projektens erfarenhet av Citylab Action i förhållande till deras eget arbete med social hållbarhet? Uppsatsen utgick från en kritisk ansats och tog avstamp i en litteraturstudie, som utmynnade i ett analytiskt ramverk och den normativa hållningen att arbetet med social hållbarhet måste innefatta en ambition att öka den sociala rättvisan. Täby Park, DrottningH och Masthuggskajen valdes som fall, och studien innefattade intervjuer med två tjänstepersoner från varje projekt och textanalyser av plandokument som var kopplade till projektens arbete med social hållbarhet. En analys av det empiriska materialet gjordes utifrån det analytiska ramverket, som innehöll frågorna: Hur är social hållbarhet (implicit) definierat och operationaliserat? Hur är projektet orienterat i förhållande till dualismen mellan utveckling och bevarande? För vem görs utvecklingen av stadsdelen? Resultaten indikerade att förståelsen av social hållbarhet, liksom det operationella arbetet, var mycket olika projekten sinsemellan. I sammanvägningen av de olika fallen framstod tendensen att marginalisera människor med små ekonomiska resurser att vara en av huvudutmaningarna för att skapa social hållbarhet. Fyra förslag ges på vad som skulle kunna ändras i Citylab Action-guiden för att på bästa sätt stödja utvecklingen av socialt hållbar stadsutveckling: Om guiden är ämnad att användas för befintliga stadsdelar bör den omfatta fler aspekter kring att ta hänsyn till och adressera befintliga invånare. Guiden bör innehålla tydligare mål för analys av hur projektet påverkar segregationsmönster. Guiden bör ge mer uppmärksamhet till skapandet av billiga lägenheter i socialt integrerade stadsdelar. Guiden bör innehålla mål för att beakta de sju diskrimineringsgrunderna och socio-ekonomisk status i planeringens fysiska resultat och inte bara i planeringsprocessen.

Examining the Effects of Climate Change and Urban Development on Water Demand: A Multi-Scale Analysis of Future Water Demand in Hillsboro, Oregon

House-Peters, Lily 01 January 2010 (has links)
In the Portland, Oregon, metropolitan area, suburban cities such as Hillsboro are projected to grow as people seek affordable housing near a rapidly growing metropolis. This thesis examines the combined impact of'c1imate change and urban development on both neighborhood and municipal scale residential water demand in Hillsboro, Oregon. I use two models, a surface energy balance model, Local-scale Urban Meteorological Parameterization Scheme (LUMPS), and a system dynamics model, CCDomestic, to investigate changes in residential water demand in the 2040s at two distinct spatial scales, the neighborhood and the municipality. I calibrate and validate each model to the reference period and then simulate the future (2030-2059) under three statistically downscaled global climate models and two urban development scenarios. The findings of this study indicate that climate change and urban development will not evenly affect water consumption in neighborhoods across a city. Instead, the current land cover and residential density of a neighborhood exert an important influence on the response. Heavily vegetated neighborhoods exhibit large increases in water demand under urban sprawl and warming scenarios, while neighborhoods dominated by impervious surfaces decrease water consumption under sprawl scenarios and show little change in water consumption under combined sprawl and warming scenarios. At the municipal scale findings suggest that water demand is highly sensitive to urban design and management and that the combination of urban densification and water conservation regulations could mitigate increases in water consumption from population growth and climate change.

Sustainable, Affordable Housing for Older Adults: A Case Study of Factors that Affect Development in Portland, Oregon

DeLaTorre, Alan Kenneth 08 March 2013 (has links)
Portland, Oregon, is considered to be a leader in sustainable development. Government agencies, nonprofit organizations, and businesses have been innovators in policymaking and practice that is aimed at creating a more sustainable city. Despite population aging, little is known about how or whether planners and developers consider older persons in terms of sustainable development. Thus, this study examined the case of sustainable, affordable housing developed for low-income adults aged 55 and older. Interviews with 31 key informants were conducted in order to answer three research questions: What is the meaning of sustainable development in Portland, Oregon, as it pertains to affordable housing for an aging society? How and why has sustainable, affordable housing for older adults been developed in Portland? What are the policies that affect the availability and appropriateness of sustainable, affordable housing for older adults in Portland? The sample included individuals who influenced the creation of senior housing (e.g., urban planners, architects, nonprofit directors) and who were identified either because of their roles within local housing development or through snowball sampling. Six Portland-area developments provided the context for studying how and why sustainable, affordable housing for older adults was planned and created in the city. The findings suggested that introducing the topic of aging into the discourse of sustainable development will lead to a more robust meaning of the concept, which can aid future research, policy, and practice. Five elements characterizing sustainable housing for older adults were identified: physical accessibility; proximity to community services; infrastructure that connects housing with services; healthy living environments; and high-quality social spaces in and near housing developments. The findings also pointed to the need for sustainable development practices to pay attention to social equity and the equitable distribution of affordable housing, including housing for older adults. Several insights into how sustainable, affordable housing for older adults developed in Portland were gained (e.g., using government subsidies; involving aging experts in integrated design processes; intersectoral partnerships that led to the city becoming an early adopter in greening its affordable housing), as well as why such housing was completed (e.g., there was a collective public-sector response to meet the need for creating sustainable, affordable housing; an emerging culture of sustainable development in Portland; urban and regional planning efforts have begun to address population aging). However, the amount of sustainable, affordable housing remains insufficient to meet Portland's aging population. Reasons identified include: the absence of specific housing policy attuned to the needs of older adults in Portland; disconnects between housing and health care and supportive services; and lack of integration of older adults in the planning, design, and development processes. Room for innovation and improvement exists in regard to healthy, accessible, green, and affordable housing policies and the development of new models of housing for an aging population. Based on this research, 10 guiding principles of sustainable development for an aging society were proposed to inform future research, as well as planning and development efforts.

Design dopravního prostředku v systému udržitelné městské mobility / Design of the Vehicle for the System of Sustainable Urban Mobility

Škaroupka, David January 2013 (has links)
This dissertation is a response to the negative trends in urban mobility, which led many authors to conclude on the need for a new approach to personal transport in the cities. The work has creative character, but in the conceptual level, it is taking into account the specific needs of sustainable urban mobility and build on the existing innovative transport solutions. The result of dissertation is a vehicle vision, understood as an element of urban mobility that respects the character of the zones of free movement of persons, but it is also suitable for transport over longer distances.
