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.

The prevailing urban migration is a worldwide process. This results in growing cities and a diminishing proportion of people living in the countryside. As the urbanization continues a large amount of the world?s population is expected to live in urban settlements of informal character by 2050. Green Belt has for many years been used to control urban growth and to secure the sustention of larger green areas around towns and cities.

This thesis is a critical discourse analysis of the vision of Malmös contemporary urban development. By analysing official documents produced by Malmö municipality our aim is to make discursive and sociolcultural practices in the constitution and construction of the city visible and problematicize them. To do so we use critical discourse analysis and theories on Urban Studies. Malmö is a city historically labeld as a ?labour- city?, with heavy industry as its main labourmarket.

Det här arbetet har undersökt huruvida konceptet reglerande ekosystemtjänster är möjligt att konkretisera och applicera i planerings-och gestaltningsarbeten. Målet med arbetet var att skapa ett gestaltningsförslag till Kloster Kyrkopark i Eskilstuna med fokus på partikel- och bullerreglering med vegetation. De frågeställningar som har besvarats i arbetet är: Hur kan man planera och gestalta med vegetation för ekosystemtjänsterna partikel- och bullerreglering och är den tillgängliga kunskapen om reglerande ekosystemtjänster idag tillräckligt konkret för att vara applicerbar i ett gestaltningsarbete? Metoden i arbetet har baserats på forskning för gestaltning. Genom en litteraturstudie, observationer, analys och samtal har allmänna gestaltningsprinciper för partikel- och bullerreducering, samt specifika krav och förutsättningar för projektet sammanställts. Resultaten från forskningen, de allmänna principerna och de specifika kraven och förutsättningarna, har sedan prövats i gestaltningsförslaget. Resultatet från gestaltningsarbetet visar att den tillgängliga kunskapen om reglerande ekosystemtjänster är tillräckligt konkret för att kunna appliceras i en gestaltning. Men det finns ett stort glapp mellan den konceptuella litteraturen som behandlar reglerande ekosystemtjänster och den litteratur som konkret beskriver hur man bör gå till väga vid luft- och bullerreglering med vegetation.

Mitt arbete innefattar en "Urban building" med bostadsrätter och kontor där utgångspunkten har varit cykeln då jag ansett den vara det mest stadsmässiga elementet. Placeringen för byggnaden är Hornsbruksgatan på Södermalm där det med projektet blir till 130 nya bostäder och 1200 kvm kontor som är väl anpassade för cykling såväl som cyklister..

Steam was used as a site preparation method to eliminate unwanted bilberry (Vaccinium myrtillus L.) in the boreal forest. The efficiency of steam to suppress bilberry was compared with prescribed burning and cutting the bilberry. Different combinations of steaming and/or cutting the bilberry were set up to investigate in which way steaming and cutting influenced the sprouting and regrowth of bilberry. The regrowth of the bilberry vegetation was monitored for 40 month. Steam was most efficient in suppressing bilberry.

Using the example of 55 former towns in Greater Poland, the author investigates the belief thattowns formerly deprived of town privileges are the most likely to be qualified as future formalurban entities. This paper approaches the subject of urban deprivation and restitution with amultiaspectual study of the concept of urbanity. Since a preponderance of Polish degraded townspossess a prominent urban physical structure, the study focuses mainly on urban morphology as acontributing factor to urbanity. Other approaches include the central place theory, demographicconditions and the role of urban perception. Taking into account Poland?s shifting geopoliticalhistory the study also seeks to identify and explain spatial patterns of varying degrees of urbanityamong the studied towns.

To regularly remove woody vegetation along the roadside of forest roads is an important part of the road maintenance, since the vegetation binds moisture in the road side and, thus, the removal makes the road drying faster with results in improved bearing capacity. Vegetation removal also makes it easier to upgrade the road by material recycling from the ditch and, moreover, the visibility along the road is maintained.The aim of the study was to evaluate what type of chain flail is the best and most cost-effective for removal of different kind of woody vegetation along forest roadsides.Time studies were made on two chain flails when removing woody vegetation in three different classes; easy-, middle- and heavy shrub removal. The studied flails were one light and rather simple flail named Optimal M160 and a heavier and more advanced flail named Slagkraft H210. The removal was made according to Holmen Skogs? specification and the quality of the cleaning was measured by objective belt inventory.The productivity was higher with the heavy flail within all cleaning classes.

Urban density is not new, but rather one side of the continous processes of change underway in the city. During the urbanizing boom of the industrialization, when the cities grew bigger, the first spaces to be built on were vacant and planted areas in the interior of the district. The gardens that once were there were replaced by yardhouses. The idea of urban density is that a dense city means less distance between residential areas and workplaces, resulting in fewer shipments and travelers, which ultimately leads to lower energy consumption and lower emissions. Urban density may lead to shorter distances, but not necessarily. In the wake of urban density the greenstructures of the city is shattered. The possibilities for green areas to contribute to the health of the city and its inhabitants is dramatically reduced.

The right to the city has lately become the rallying cry for many urban social movements all over the world to challenge neoliberal planning, gentrification, the privatization of urban commons and growing spatial and social gaps in city and society. This senior essay studies urban social movements that in different ways advocate the idea of the right to the city. The term right to the city was coined in the late 1960s by French urban theorist Henri Lefebvre, who promoted the idea of the city as a common, a space belonging to everyone. The right to the city is not ?a return to traditional cities?, but ?a right to urban life? (1996:158).This study focuses on the city of Hamburg.

Uppsatsen behandlar temat urbana tillväxtstrategier i svensk planering. Studien syftar till att undersöka hur översiktsplaner har påverkats av entrepreneurial city, platsmarknadsföring och kreativa klassen som alla är olika teorier om urban tillväxt. Undersökningen utgår ifrån fem kommuner med en översiktsplan från tidigt 90-tal och en aktuell plan antagen omkring 2010. Översiktsplanerna studeras utifrån de valda teorierna (entrepreneurial city, platsmarknadsföring och kreativa klassen) om urban tillväxt för att ge förståelse för hur strategierna i kommunernas översiktsplaner har påverkats av teorierna. Den genomförda undersökningen visar på en förändring över tid som pekar mot mer tillväxtorienterad planering..

Urban trees contribute significantly to our society. By providing ecosystem services and a habitat that other urban species and ecosystems depend on, both biodiversity and the people in the city benefit. Some characteristics that the trees possess include functioning as biological filters for the atmosphere and water, as well as positively impacting people's mental health. However, urban trees are challenged by stressors such as pollution and a drier environment, making them particularly sensitive to climate change. The goal of this study was to estimate the expected magnitude of climate change in Gothenburg and compare it with the current urban species' natural climate boundaries to understand the extent of the climate threat and which species appear to be most at risk.

The purpose of this study is to examine how risk is perceived by the urban architect's in the region Dalarna, as well as how this is reflected in their everyday work with risk and decision- making according to urban planning. The ambition is also to show how their risk awareness could be improved. The study is written in cooperation with Länsstyrelsen Dalarna as a part of their regional long-term goal to improve the region's proactive risk' and crisis management. The study is based upon 12 semi-structured interviews with local urban architects conducted during the summer and autumn 2007. The result shows that some architects are motivated for working with risk and think that risk awareness should be integrated in their everyday work, while others are not motivated and think that risk is more of a passing trend.

Litteraturstudien tar upp ämnet trygghet, där målet har varit att förklara vad det är som uppfattas som otryggt i de vegetativa miljöerna samt hur vi i dagens samhälle bäst kan arbeta med den angränsande vegetationen till gång- och cykelbanor för att öka tryggheten där. En empiriska studien som gjorts är baserad på tre gång- och cykelstråk i Lomma kommun. Platsernas vegetation har inventerats och problem ur ett trygghetsperspektiv har noterats, och utifrån det har förslag på åtgärder angetts. Den slutsats som kunnat dras är att kontinuerlig skötsel av vegetationen på en plats är ett krav för att kunna behålla en struktur och kvalité som inte upplevs som otrygg.
