Att styra bilanvändning mot en hållbar utveckling. Om geografiska livsvillkor kontra offentliga ingrepps betydelse för bilanvändning.

Car usage is determined by several facts, e.g. living conditions determined by geographical matters. There is a political will to control car usage with different kinds of incentives since car usage generates environmental problems. This essay analyses the differences between car usage in urban areas as opposed to thinly populated areas in Sweden and their significance on governmental incentives. By using statistics differences in car ownership during ten years between thinly populated areas, areas in the countryside and urban areas is studied.

Potentiellt förorenade områden i Ljungans avrinningsområde i Västernorrlands län : Finns det anledning att prioritera om arbetet med avseende på riskläget för översvämning, ras och skred?

Due to the climate change natural disasters expects to increase and in some areas the conditions for dissemination of hazardous pollutants from contaminated areas could be affected. Different inventories and mapping has been made to identify areas of risk for flood or avalanche around the country. At the same time inventory and treatment of potential polluted areas (MIFO objects) is progressing. In Ljungans run of area in Västernorrlands county is a exposed area due to the amount of clay and silt in the ground that are sensitive in the context avalanche. The area has also a lot of MIFO objects and risks of flood.This essay aims to investigate what data material that is available regarding MIFO objects, flood- and avalanche risks in Ljungans run of area in Västernorrlands county.

Avgränsning av tillrinningsområden till grundvattenmagasin : vilken information ger berggrundens överyta?

Delineation of recharge areas for aquifers is performed in the groundwater mapping process at the Swedish geological survey, SGU. This work is time consuming and performed manually. It is therefore desirable to develop a more general and repeatable method for defining recharge areas for aquifers.The purpose of this study was to investigate two other possible methods to delineate recharge areas for aquifers. The first method was to examine the possibility of using the topography of the bedrock to define the recharge areas for aquifers. To enable this, a method for generating the topography of the bedrock was developed.

Svartgran ? ett alternativ när allt ser mörkt ut? : en kartmodell för att visa lämpliga ståndorter för odling av svartgran

A common problem in forestry is plant death caused by frost. The risk of frost is highest on wind protected, flat or low-lying areas in the terrain. Here you often have regeneration problems with Norwegian spruce which is especially sensitive to spring frost. Swedish tree experiments have shown that the black spruce can be a suitable alternative on these areas, for example on moisture frost prone areas. The species originates from North America and its pioneer tree characteristics make it more frost hardy than Norwegian spruce.

Marina visioner : nya idéer för småbåtshamnen i ljuset av utveckling, urbanisering och klimatförändring; tillämpat i Rydebäck.

New dwellings and commercial buildings in coastal regions has for some time now been a focal point. Old industrial harbours are regenerated into modern living areas with a recreational purpose. In Sweden the marina has not taken part in this development, thus remained in the monotony and large-scale structures of modernism. This graduation thesis looks upon the marina from a landscape architects point of view, where the marina foremost is a social venue. By revealing and discussing the development of the marina, its design and environmental consequence theories of the marinas future is presented. These theories are later tested upon the costal village of Rydebäck, south of Helsingborg. The thesis is structured in three parts: marina knowledge, proposal and resources. In the first part the historical development of the marina from prehistory time to now is discussed.

Kartläggning av markberedning i svår terräng på SCA Skog

Due to the requirement for reduced use of insecticides and the lack of competitive mechanical plant protection, you need a scarification with good result. This is often no problem to perform in normal terrain without technical barriers. However, in difficult terrain with large number of rocks and steep slopes, the result would be worse. The purpose of the study is, that in these areas with difficult terrain, to find out the scarified areas quality, describe the non-scarified areas conditions and find out where the limit is for the use of a traditional disc trencher. Findings indicate that there are usually not the machine that is the limit, but the driver of this.

A survey of cassava plants in the coastal region of Tanzania showing severe symptoms of cassava mosaic disease

Cassava (Manihot esculenta Crantz) is a root crop that plays an important role in many households in Africa. It is sometimes called ?Africa´s food insurance?.

Grundvattenskydd och markanvändning i tre olika länder- effekter för miljö och samhälle

AbstractDrinking water is an important resource on Earth both for humans and animals. Although most of the surface is covered by water only a small quantity is available as drinking water. Our manner of living creates a lot of pollution which has an environmental impact. Groundwater has a protracted turnover time in the soil and it can take many years before the effects of human impact are detected. The Swedish environmental object is ?Good groundwater quality? which aims to provide a safe and sustainable supply of drinking water today and in the future.

Riksdagsvalet 2010 : En GIS-analys

Our social lives and where we live shape our choices in life. One of those choices is which party we vote for in the general election. The aim of this thesis is to see if there are any connections between the Swedish general election of 2010, demography, socioeconomic factors and geography. This is done with regression analysis and chosen variables. Another aim is to see where in Sweden the chosen variables aren?t enough to explain the results of the election.

Havsnivåhöjningens påverkan på Gotlands kust och strandängar år 2100

Den globala havsnivåhöjningen är en direkt följd av den globala uppvärmningen ochkommer i framtiden påverka stora områden i kustregionen. Syftet med detta arbete äratt öka förståelsen samt se hur Gotlands strandängar samt kustområden kan påverkas avhavsnivåhöjningen år 2100 och se vilka eventuella följder detta kan leda till. Metodernasom har använts är GIS-analys och litteraturstudier. Höjdmodeller med olika upplösningjämfördes även för att undersöka vilka som lämpar sig till en liknande analys införframtida studier. Resultatet visar att vid en havsnivåhöjning på 1 m kommer 97 % avstrandängarna försvinna och vid en havsnivåhöjning på 2 m försvinner 99 % av degotländska strandängarna.

BIODIVERSITETS P?VERKAN P? M?NGDEN ORGANISKT MATERIAL I ALSUMPSKOG: En fallstudie i fyra alsumpskogar p? svenska v?stkusten

Globally, coastal ecosystems like mangrove forests, sea grass meadows and salt marshes are well known for their ability to capture and store atmospheric carbon effectively. In Sweden, there is still limited knowledge about local coastal ecosystems with similar functions, with alder swamp forests being an interesting example. Therefore, this study aimed to increase knowledge of the factors that can contribute to the potential carbon sequestering ability of alder swamps. Vegetation data and sediment samples were collected from a total of 37 sampling plots across four alder swamps in Bohusl?n on the Swedish west coast.

Grus i maskineriet : en fallstudie om förbättringspotential

Grus i maskineriet ? en fallstudie om förbättringspotentialVäxeln AB, a company that provide sales, service and repair of industry gears, has contacted the authors of the essay and asked us to investigate in which areas of the company that has improvement potential. Persistent improvement is a recurring and up-to-date issue that many business leaders not put enough resources on. A big problem in many companies is the issue that there is no comprehensive view and therefore some of the workers tend to not follow the routines that are required for the whole system to work.The goal with the essay is to give Växeln AB advice on to which areas in the company that have improvement potential.We have used a qualitative method with mainly semi-structured interviews which has led to an inductive approach. 13 co-workers that work in different areas of Växeln AB have taken part in the interviews.

Den svarta jordens mysterier : en jämförande studie av två aktivitetsytor på stenåldersboplatsen Ajvide

The Pitted ware dwelling site Ajvide on the west coast of Gotland in the Baltic Sea is, because of its long continuity from the late Mesolithic to the middle of the Scandinavian Bronze Age, an interesting research object concerning Stone Age in the Baltic area. In this essay, a comparison between two activity areas on Ajvide have been carried out in the purpose of finding out what these areas may have been used for during the middle Neolithic.  It has been showed, through zooarchaeological analyses of animal bones, that the areas most likely are depositing sites for slaughters refuse and food debris. If it is a result of everyday or more ceremonial activities is left undetermined..

En intervju och enkätstudie av besökare i tre tätortsnära skogsområden i Stockholmstrakten :

This Masters thesis is made as the first of two visitor surveys of three urban forest areas. These areas are; Skutan recreational area in Haninge, Ugglevikskällan on Norra Djurgården in Stockholm and the Paradiset Reserve in Huddinge. The study is made in cooperation with the managers of the three areas operating within the European Union Life Project regarding Urban Woods for People. The goal has been to collect data through studies of visitors and close by residents in the three areas. The results are to be used as primary values for the follow-up as well as a basis for managerial decisions. The interviews and surveys are also constructed in a fashion so that they can be used for the follow-up study. For the Skutan recreational area the mode of contact was by sending forms to the nearby residential areas.
