Biologisk mångfald i staden och dess närhet : möjligheter att som landskapsarkitekt främja biologisk mångfald
In a time of increasing Urbanization the human tenure effects on the land has lead to a decrease and fragmentation of areas that are valuable to urban wildlife. These actions have had a detrimental effect on the species and habitats that exist in cities and towns.This paper investigates, through the study of relevant literature and the undertaking of interviews and field visits, the role that biodiversity plays in our society. The current attitude towards urban biodiversity and the responsibility for its promotion within the landscape architect profession has been explored.This paper includes three English case studies and a design proposal investigating how one can work to promote biodiversity on a smaller scale.This paper concludes that urban biodiversity is multi-functional ? being of ecological, social and cultural significance. The landscape architecture profession must be aware of the need to combine a variety of different factors such as economical, social and environmental aspects.
Ekosystemstödjande och multifunktionella växtval i urban miljö : En fallstudie med utgångspunkt i Nacka stadsbildning
This study has investigated how urban vegetation can be used in a multifunctional way to support ecosystem services in urban environments. Nacka municipality is in the start-up phase of building what is to become Nacka city. This provides a unique possibility to study and analyse what role the vegetation play in making the city a healthy living environment and how it needs to be adapted in order to be resilient against changing climate conditions and how the effects of those changes can be regulated. The study further investigates how airborne pollution, caused by Urbanization processes, can be regulated or reduced by vegetation or species selection. Methods used in this study were a combination of qualitative interviews and literature studies, seeking to answer the questions: Which specific ecosystem functions are needed in the urban environment and which aspects will influence the ecosystems ability to deliver the functions in demand? And which plant species have the right mechanisms needed to deliver those functions? These questions have been studied and analysed in a local based context where the local conditions ands site specific needs of Nacka define criteria for plant selection.
Re-design of Toledo Riverfront : from industrial past to sustainable biodiverse future
Effects of climate change, Urbanization and global homogenization are resulted in the degradation of land and losses of natural habitats. Ecological design integrates nature into urban environment by respecting natural ecological principles and processes and creating resilient
urban biotopes which also can be used by local urban communities.
The aim of the thesis is to answer the research questions: How ecological design principles can be applied for re-design of Toledo Riverfront (with requirements of the design competition)? and What is the ecological design in landscape architecture? I participated in the USA design
competition with the aim to create a vision and redesign of Toledo Riverfront in Ohio State, USA. The site is located in the south point of Lake Erie. As a result of a long industrial activity, riverfront of Toledo had been transformed into inaccessible and abandoned brownfields.
In my proposal I applied ecological design principles on three scales:
the city of Toledo by reinforcing of ecological connection and creating green corridors along the river; the intermediate scale by suggesting public parks along the river front and on the fine level by proposing detailed design including remediation of the site and use of dredged
material.
Den svenska lönebildningen i förändring
Problem: The Swedish wage-setting has changed since the time for the breakthrough of the industrialism until today. Before that, wages often consisted of perquisites or goods that could be exchanged against other goods. Rural people were often self-sufficient. In some cases the farmer owned the land, in other cases they where tenants. At the time for the breakthrough of industrialism the demand for similar labour were increased.
Green-urban balance : a proposal for balancing green area preservation and urban development in the city of Uppsala
Rapid Urbanization causes competition over land use between green area preservation and urban development in cities and greatly affects ecosystems as well as human well-being. This conflict is significant all around the world as many cities are now replacing existing green areas with new developments. The area around Dag Hammarskjöld's väg in Uppsala is currently experiencing the same conflict, as the need that the city has for new housing represents a threat for the many valuable green areas that are in the site. The purpose of this project was to understand how the need of urban development and the preservation of green areas could be balanced. This understanding would thereafter be used to make a design proposal for the area around Dag Hammarskjöld's väg.
Utvärdering av anaerob behandling av hushållsspillvatten och tekniker för efterbehandling
The continuous process of Urbanization results in demands on research and development for ecological and sustainable city development. Because of this, the current systems for wastewater treatment may have to be improved. In order to evaluate new technologies for municipal wastewater treatment, a development project has been initiated for the new district Hammarby Sjöstad in Stockholm. The project is lead by the company Stockholm Water. High environmental standards have been put up for the district, as it must be twice as good as an ordinary new district.
Hylasmotivet hos Apollonios Rhodios och Theokritos
An increasing global population and a worldwide growing Urbanization has raised the questionabout the future food security in cities all over the world. Peak-oil limits the access to cheap fossilfuels which threatens the global food-supply chain. This has resulted in a larger awareness anddiscussion related to urban agriculture. Growing crops and keeping animals within the city-borderscould be one way of creating a more robust and sustainable food supply for city dwellers. However,to enable an expansion of the urban agriculture many theorists argue that policies and institutionalstructures that supports and promotes city farming have to be developed.

Urban Agriculture i den hållbara staden : en fältstudie i Managua
The way we design our cities today will affect the living conditions for future generations. Planning as a discipline can become crucial to attain a sustainable urban development with an increased quality of life among the urban population and an improved environment.
Urban Agriculture in the Sustainable City -a case study in Managua is a Diploma Work that deal with poverty issues, aspects of sustainability and development work. We have had a theoretical starting-point, but our focus has been on the case study i.e. the practical part, that we carried out in Managua, the capital of Nicaragua.
Today about half of the worlds 6,3 billion people live in cities. The demographic growth of the countryside has declined, while the population in the cities is considerably increasing.
Att veta Gudarnas hemlighet : En sårbarhetsanalys av omständigheterna kring stormen Gudrun med pressure and release modellen
The concept of vulnerability is the capacity or the sensitivity to become damaged. Vulnerability are characterized by one or more of the following terms; a system´s sensitivity to exposure to shock, stress or interference, the state of the system in relations to a threshold of damages, and the system´s ability to adapt to the changing circumstances. Vulnerability in this study is referring to the sensitivity of the circumstances that lead to sustainable livelihood that can´t be maintain and that there is an inability to cope with and manage stress. The choice of making a study in this area is based on that action needs to be taken to moderate the vulnerable aspects of society, in this respect in relations to storms. Analyzes of the social vulnerability to climate change or natural events is needed for effective actions.
Presence of Japanese Encephalitis virus vectors in Can Tho City
Japanese encephalitis virus (JEV) is a significant vector-borne zoonotic pathogen, causing devastating encephalitis in humans. Its geographical range includes a majority of Asian countries and has also been recognized in some western Pacific areas. The main vectors of JEV are mosquitoes belonging to the genus Culex. Birds and pigs function as hosts and virus amplifiers, whereas humans are accidental hosts. Japanese encephalitis is commonly regarded as a rural disease.
Skolråd, bidrag och inspektion : Den fortsatta etableringen av ett statligt skolväsende mellan åren 1871 - 1882
This study investigated a local aspect of theSwedish elementary school modernization process between the years 1871-1882.Previous studies have been drawn from the school inspectors own reports andshow that the schoolboards housed a negative and resentful attitude towardsreforms and the school inspectors often felt that the parish priests were moreinclined to changes than the schoolboards themselves. Other research on elementary schoolmodernization has stressed the matching grants as a major cause of developmentand further establishment. In this study, however, a schoolboards own notes inthe form of meeting protocols during an eleven year period as well as a letterby a priest Erik Lundberg, Redogörelseför skolhusfrågan i Tierp dated 6 October 1880 were analyzed to see if theprevious explanation of school modernization, in particular with regard to thereluctance to change by the schoolboards goes to demonstrate and confirm. Theresults of this study have shown that even if the schoolboards do notimmediately follow the school inspectors instructions, it seems not primarilybeen due to resentment. Reforms within the school world are well known forbeing time-consuming but for the current period, as this study concerns andwithin this specific parish there were conflicts of interest which are notshown when only the inspector?s accounts and reports are examined.
Att bygga för att synas - city branding i stadsplaneringen :
Spectacular buildings and categorized districts are becoming more common elements in cities. In many cases, they are the result of city branding, which means choosing a city image and dealing with it like a brand to profile and compete against other cities. This essay study what impact on and roll in urban planning the trend might have. The first part relies on literary studies and describes what has been written about city branding. The globalization, the experience economy, urban management, Urbanization and the theory of the creative class are pointed out as driving forces of the popularity and the spread of city branding.
Är den hållbara staden möjlig utan en levande landsbygd? : en studie av den miljömässiga hållbarheten i Det flerkärniga Skåne
Stora delar av världen genomgår idag en omfattande urbanisering, där allt fler flyttar från land till stad. Samtidigt ges diskussionen om hållbar utveckling mer och mer relevans och utrymme. Som en följd av rådande urbaniseringstrender tycks resonemang kring miljömässig hållbar utveckling ofta beröra hur de urbana strukturerna ska kunna komma att möta framtidens klimatutmaningar, snarare än att alternativa strukturer lyfts fram som möjliga, mer miljövänliga, alternativ.
Denna uppsats syftar till att ge en djupare förståelse för vilken betydelse relationen mellan stad och landsbygd har för en miljömässigt hållbar utveckling. Uppsatsen tar sin utgångspunkt i en beskrivning av och diskussion kring miljömässig hållbarhet (och icke-hållbarhet) i staden respektive på landsbygden. Denna beskrivning och diskussion ligger sedan till grund för en analys av huruvida Region Skåne förhåller sig till de miljömässiga fördelar en stärkt relation mellan stad och landsbygd innebär.
Förändringar i markanvändning över tid och dess påverkan på vattenkvalitet
The EU Water Framework Directive has led that management follows the boundaries of natural catchments.The Swedish waters suffer from a nutrient overload that originates mainly from diffuse sources such as agriculture and the subcatchment of Hackstabäcken in Vallentuna Kommun, just north of Stockholm, has been chosen for this study because of its high nutrient load and because it has undergone obvious changes in land use through the years.In this study, the land use in 1902 is compared with the land use in 2011 in order to investigate if it has influenced the ability of the landscape to produce ecosystem services related to nutrient removal. These services will continue to be produced as long as the system is stable and resilient, but when landuse changes and manure from horses increases it will lead to disturbances that can convert a system from one regime in to a completely different one. That will result in loss, or degradation, of ecosystem services such as denitrification, phosphor sedimentation and adsorption, vegetation uptake and infiltration.The results of this study are based upon area calculations of landuse from old maps from 1902 and 2011. Through these maps it becomes clear that the forests in Hackstabäcken, has increased with 170 ha together with an Urbanization of 311 ha, at the same time as wetlands and arable land has diminished and lakes has suffered from reductions. Wetlands have been reduced with 76 ha and the ones remaining are of insufficient quality from a nutrient removal perspective.Data from 1902 and 2011 regarding number of horses and bovines indicated a decrease in bovines and an increase in horses.
