It is estimated that 22 000 contaminated areas exist in Sweden today. In order to classify the risk of contaminant migration from these areas and to prioritize which of these contaminated areas should first be treated, the Swedish Environmental Protection Agency (EPA) has designed a method, for the investigation of contaminated areas (MIFO). One of these contaminated areas is the landfill Gräsötippen outside Köping. The landfill has been used by both Yara AB and the Köping municipality between the years 1945 and 1975, and both industrial and household waste have been deposited there. The aim of this report is to survey which contaminants that can be found in the soil and water in the landfill Gräsötippen and to evaluate the migration of these contaminants.

När glöden falnatEn urban begravningsplats i fridfull naturVar kommer jag att begravas?Idag flyttar fler och fler in till storstäderna, och man lämnar ofta släkten kvar på hemorten.  Det nya livet i storstaden byggs upp runt arbete och de nära relationer till vänner man får, och inte uppbyggda på släktskap. Som storstadsbo kanske man inte identifierar sig med ?hela? Stockholm, det som innefattar de främmande förorterna, där inga anhöriga eventuellt kunnat bo, utan mer med staden ?som sådan?.Om man då mitt i livet avlider ? skulle lösningen vara att skickas till födelseorten för en jordfästning?    I mitt fall finns ingen familj kvar där, föräldrarna är döda och syskonen är spridda över landet.

As the number of inhabitants increases, the cities expand into the former rural landscape. The urbanization causes changes to the functioning of the peri-urban fringe. Land that previously was used for agricultural production is now used for alternative enterprises, as for example horse keeping and recreation. 75 % of all horses (approx. 200 000) are situated in the peri-urban fringe.

Cultural heritages are environments created by humans that are considered to have a conservation value for the posterity. They can be seen as one of society's non renewable resources. It is important to have knowledge of how cultural heritages are affected by future climate changes.The water flow in Uppsala is estimated to increase during winter and decrease during spring and summer. Precipitation will gradually increase as well as the intense short period precipitation. The average temperature is estimated to increase as well.

Digital depth-to-water maps can be produced from a digital elevation model (DEM). Then GIS- based algorithms are used to calculate water flows and the depth-to-water index classes dry, fresh, moist and wet. The purpose of this study was to investigate the possibility to use depth- to-water maps for site adapted planting.The results showed that use of depth-to-water maps for site adapted planting, roughly halved the proportion of improperly planted surfaces from an average of 9 % to 4 %. The variation in the values of proper surface decreased and the result became more even.. In addition, more pine than spruce was incorrectly planted.

I takt med Försvarsmaktens ökade engagemang internationellt och det faktum att alla insatsförband inom Försvarsmakten ska kunna verka på alla konfliktnivåer och i en urban miljö kommer nya krav och behov på bekämpningsförmågan att uppstå avseende precisionsbekämpning.Med hjälp av ett GIS kopplat till EOI:et vid en insats i en urban miljö kan en rad vinster erhållas för att stödja artilleriet vad avser precisionsbekämpning. Exempel på sådana områden är: målverifiering, justering av målkoordinater, lägesuppfattning avseende målets närmiljö, redovisning och presentation av verkansområde inför en insats för dimensionering av verkan..

Denna rapport presenterar, på uppdrag av Umeå Energi, projekteringen av ett urbant vindkraftverk. Första delen av rapporten beskriver kortfattat teorin bakom urban vindkraft och dess skillnader mot storskalig vindkraft. Andra delen redovisar projekteringen av ett vindkraftverk placerat på Strömpilenområdet i Umeå. Detta verk är planerat att ingå i projektet Hållbara Ålidhem, ett projekt där Umeå Energi samarbetar med med AB Bostaden och Umeå kommun med målet att skapa ett tryggare, trivsammare och energisnålare bostadsområde.Urban vindkraft innebär att småskaliga vindkraftverk placeras i bebyggda områden, en ny och växande marknad. Med småskalig avses vindkraftverk med en installerad effekt upp till 100 kW, att jämföra med dagens storskaliga vindkraftverk som har en effekt på runt 2 MW.Projekteringen av urban vindkraft är problematisk.

Studies show that the interest and knowledge about science among teenagers is decreasing. They also reveal the difficulties to explain the ecological processes and that the ideas about the nature are collected from everyday life and early school years.The intention of this investigation was to find out more about children?s ideas and knowledge about the ecological processes and to compare these results with the curriculum.The method was a questionnaire and interviews with children in school year 1 ? 6. The aim of the studies was also to find out if any progress connected to age could be found, concerning understanding of the ecological processes.The results showed difficulties in achieving the predestined goals for biology and chemistry concerning ecology cycles and they differed a lot between the children. Often the learning process showed very little progress.

In Sweden, reduced tillage usually means non-inversion tillage, where primary tillage is carried out using chisel ploughs or disc implements. Primary tillage method is mainly determined by the desired soil loosening and the handling of soil residues. The effect of tillage depth was studied in field experiments in Skåne, Väderstad, Uppsala, Örebro och Västerås in different crops; spring oilseed rape, spring wheat, winter wheat and spring barley.The experiments generally had a randomized block design with the treatments mouldboard ploughing, deep chisel ploughing and shallow chisel ploughing, in some cases also shallow discing and no-tillage. In the experiments the following parameters were determined: seedbed properties, saturated hydraulic conductivity, penetration resistance, number of emerged plants and crop yield (all parameters were not determined in all experiments. Root growth and draught requirement were determined in two separate studies. There were no significant differences between tillage depths in non-inversion tillage in seedbed properties, plant emergence or root development.

Urban forests are important for people to get at break and be able to relax in a stressful world. Several studies show that we feel better through being out in the forest and historically this was the normal environment for us. As a result of population growth and urbanization we tend to spend less time in nature nowadays than before. Due to this development urban forests have become a central role in our society as a place where people can fulfill their needs and interests. The management of the urban forest is therefore important, especially for municipalities that own forest which is supposed to be of benefit to local residents.Falköpings municipality owns approximately 260 hectares of forest in the popular and most visited recreational area along Mösseberg?s southern slope.

Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.

Optimization of soil tillage and crop rotation is important in many aspects, but particularly in maximizing profit margins. Since the economic outcome is usually decisive, it can be interesting to study different combinations of soil tillage systems and crop rotations in order to identify the maximum economic outcome. How a crop functions in a particular tillage system determines whether it is profitable to grow that crop. Different tillage systems affect the soil and its processes in different ways. Reduced tillage often works best on weak-structured heavy clays and on silty clays.

The out-of-town retail establishments are part of the dramatic structural changes in the retailing of food and groceries. There are however strong indications suggesting these establishments result in negative externalities concerning areas such as pollution and urban environment. The purpose of this study is to describe and, from an economic perspective, analyse the Swedish political regulations and planning policies concerning the out-of-town supermarkets. The analysis establishes that the current regulations regarding out-of-town retailing do not, due to the occurrence of market failures, produce an optimal situation. It might therefore be necessary to change the planning policies in a more restrictive direction.

The Go Down Arts Centre is a proposal for a new building to an existing organisation in Nairobi, Kenya. The proposal relates to the scale of the city by making a statement on a future urban path, and by welcoming the city in to the building. The proposal houses both activities affiliated to Go Down, such as studios and rehersal rooms, as well as opportunities for the visitor to meet and interact with the culture produced at Go Down, both in formal and informal settings. The building is closed to its surroundings, apart from a grand entrance towards the urban path. There, the city passes through the building to an inner courtyard, where the communication to all the rooms and activities takes place.
