The forest and mire landscape surrounding the north Swedish villages have been of fundamental importance through time for the farmers. In the Scandinavian summer farm system the forest and mire pasture was used to its full potential. The system consisted of smaller summer farms some kilometres from the main farm in the village, and were the livestock grazed in the forest around the summer farm. The livestock affect their environment, and grazed forests generally contain a higher biodiversity than an ungrazed forest. The overall aim of this thesis is to understand the impact of livestock grazing on a northern forest ecosystem over a long time period.

This thesis focuses on the construction of drystone walls in the county of Sm?land, as well as their historical value and significance to the county. In Riksantikvarie?mbetets Plattform Kulturhistorisk v?rdering och urval, a directory for historical evaluations of buildings and objects, the first clause is to describe the object and its history. When trying to do this, the lack of literature focusing on the constructional elements of drystone walls and their history became an issue and is what prompted the writing of this thesis. With a study of different handbooks, a compilation of the constructional elements of the walls were put together.

Avsikten med uppsatsen är att undersöka vilka handelseffekter Sveriges inträde i EU 1994 har medfört på handeln av frukt och grönsaker. Vi har även undersökt hur inträdet har påverkat handeln med tredje land. Med hjälp av Trumans metod har vi analyserat frukt och grönsaker på aggregerad samt disaggregerad nivå. Analyserna samt diskussionerna som förs i uppsatsen utgår ifrån handelsomfördelning och handelsalstring, vilka är de två handelseffekter metodens sex olika utfall påvisar. Då vi studerade en tullunions uppkomst och dess konsekvenser på handeln förväntade vi oss en handelsalstring inom unionen samt en handelsomfördelning gentemot tredje land.

Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between regions. In this study, I investigated if landscape structure (e.g. agricultural dominated landscape opposed to forest dominated landscape), forage availability, population density and disturbance (e.g. roads and settlements) affect bark-stripping frequency.

Finland präglades under efterkrigsdecennierna av både ekonomiska och politiska problem. Finland hade ekonomiska problem efter att de varit med i Andra Världskriget, de skulle betala ett stort krigsskadestånd till Sovjetunionen och det krävdes stora summor för att återuppbygga landet. Det var på grund av de ekonomiska problemen stor politisk instabilitet i landet, Finland hade mellan 1950 och 1959 tretton olika regeringar. Push and Pull teorin användes till denna uppsats, Finland var ett typiskt push-land, det vill säga ett land med negativa förhållanden med hög arbetslöshet och stor bostadsbrist. Medan Sverige var ett pull- land alltså ett land som har ekonomiska framgångar och hög arbetslöshet och var därmed ett land som människorna från ett push-land flyttar till. Syftet med uppsatsen är att undersöka bakomliggande faktorer till varför människorna ville flytta från Finland och varför de flyttade just till Sverige.

Hybrid aspen is a crossbreed between European and North American aspen. It is a fast growing tree species that has shown strong growth in the South of Sweden. The follow-ups that have been made on hybrid aspen stands, have mainly been done on plant material in the South of Sweden. In the North of Sweden, only occasional studies have been made, and the knowledge of Northern hybrid aspen stands is, thus, unsatisfactory.In the South of Norrland, land owners have planted hybrid aspen, but what kind of plants it is, and how well these stands have established, is not ascertained, since data has not been compiled on the subject.The objective of this study is to evaluate practical plantations of hybrid aspen in the South of Norrland regarding height growth, survival and damages. The ambition is to increase the knowledge about practical plantations regarding height growth, survival and damages, and from the conclusions thereof, give recommendations for future establishments of hybrid aspen in the area.For the study, eight hybrid aspen stands in the South of Norrland were localised.

70 % of the lakes and waters in the water district of northern Baltic Sea do not reach the requirements for good ecological status. This is mostly due to eutrophication caused by a too high deliverance of nutrients from agricultural land or effluents. Losses of particulate phosphorus through water erosion contribute to a great extent to this eutrophication. In the action plan for the water district cover crops are mentioned as a measure for reducing losses of phosphorus from arable land. This paper reviews the possible effect of cover crops in the water district and discusses what crop that would be most suitable.

The scope of this project is to make a comparison of costs associated with wind and nuclear power in order to decide which one of these is the most suitable in the case of an increased demand for electricity. It is also investigated if there are other factors that can influence the choice of energy source.An average cost is calculated in terms of kronor per kilowatt-hour (SEK/kWh) using cost of investment, operation & maintenance and taxes & subsidies. Total investment cost is recalculated to production cost using the annuity method at three different interest rates (6%, 9% and 12%).The comparison is made between three cases of wind power and two cases of nuclear power. For wind power there are two ocean-based (300MW and 100MW installed capacity, respectively) and one land-based (60MW) wind farm. For nuclear power there is one EPR-reactor (1600MW) and one AP1000-reactor (1100MW).

Hur kan samspelet mellan objekt och plats se ut och vad kan det kallas? Genom litteraturstudier och observationer undersöks samspelet mellan konstverk och allmänt tillgänglig plats. De objekt som undersöks är konstverk i tre olika miljöer; en stadsmiljö, en naturmiljö och en park, vilken kan ses som en blandning av de två förstnämnda. Syftet med är att genom litteraturstudier och observationer undersöka samspelet mellan dessa tre konstobjekt och platser och på så sätt försöka utröna om ett konstnärligt förhållningsätt kan appliceras i platsskapandet även inom landskapsarkitekturen. Dessutom diskuteras om enskilda objekt kan väcka medvetenhet om en plats och stärka platsens identitet.

Markus och Kitayama definierar oberoende jag som ett jag som är självständig och separat från andra individer. Kollektivt jag definieras som ett sammankopplat till andra individer. Syftet med studien var att undersöka vilka upplevelser kring identitet som en person med invandrarbakgrund har. Målet var även att undersöka vad som påverkade individens upplevelser kring identiteten. Åtta intervjuer genomfördes genom chat, där deltagarnas ålder varierade mellan 20-46 år.

Swedish beef production has during the past year decreased while the consumption has increased. It´s imported beef that takes market shares. The purpose with this degreeproject is to investigate if the restaurants in Sweden are using imported or Swedish beef and the reason for their choice. The purpose is to find out if there is something the Swedish beef producers can change to increase Swedish beef in restaurants. My expectation is that the demand for Swedish beef will increase in restaurant and later even among consumers. I have interviewed ten chiefs in different restaurants and asked them the following questions: Is it the price, quality or something else that influences your choise? Does it matter to their customers if they serve Swedish or imported beef? How is the marketing of Swedish beef? It appeared both Swedish and imported beef on the restaurants.

This study examines how farmers certified by KRAV face proposed regulations on organic soils put forward by KRAV economic association among others, and how they are affected economically. These soils are, from an environmental perspective, interesting as a target for production regulations as they cause greenhouse gas emissions through decomposition of organic material when cultivated. The regulations advocate that organic soils should be grown with pasture where soil cultivation is only allowed every fith year which implies that possible adjustments of cultivation have to be made in order to fulfill the regualtions. Collection of data have been made through a questionnaire sent out to 574 farmers certified by KRAV. The answers have been analysed using a decision making model and statistical findings suggest that proportion of organic soils, type of production, economic conditions and farmers? goals and values have an influence on whether the regulations and potential cultivation adjustments have been considered or not.

Problem: Leveranser av IT tjänster från lågkostnadsländer till Sverige.Syfte: Att ta reda på hur svenska företag ser på leveranser av IT tjänster från lågkostnadsländer och ta reda på vilka drivkrafter och hinder som existerar. Eftersom Indien är det land som står för de största volymerna vad gäller produktion av IT tjänster så blir det naturligt att fokusera mest på det landet.Teori och modell: Idag produceras hälften av världens IT tjänster i Indien. Svenska företag ligger ungefär tre år efter sina brittiska och amerikanska kollegor vad gäller att köpa IT tjänster från Indien.Metod: Vi valde en kvalitativ metod för att få fördjupad information kring ämnet och genomförde nio intervjuer med olika svenska företag. Förutom dessa intervjuer hämtade vi data från publicerade artiklar.Resultat: Vår undersökning visar på att Indien är ett land att satsa på vad det gäller leveranser av IT tjänster. Att hitta tillräckligt stora IT projekt för att Indien ska ses som lönsamt, verkar vara det främsta hindret.

In the near future we need to reduce the greenhouse gas emissions significantly for the benefit of the environment around us. The European Union has de-manded a variety of climate and energy goals to be achieved by year 2020, the ?20-20-20? targets. With these aims, The European Union means that we must reduce our emissions from fossil fuels and instead increase our renewable fuels. With stump harvest in the forest it?s possible to increase the use of renewable fuels and reduce our emissions from fossil fuels.

In connection with the admittance of the EC-directive (99/31/EC) in Swedish politic, through the constitution of waste depositing (2001:512) at year 2001, the rules about management the landfills and leachates tightened. At the landfill Vissberga in the municipality of Hallsberg, a leachate treatment plant was constructed just a year thereafter. This treatment plant consisted of an aerated pond with a following land treatment and a willow cultivation to replace the land treatment during the summer. In this case the parameters, which were estimated as the most important to reduce, were iron and nitrogen. The iron would react with the oxygen-rich water in the aerated pond and precipitate to ferric-hydroxide and than settle in a calm zone of the pond.
