Trädens utveckling efter att de har lämnats som naturhänsyn : tillväxt, mortalitet och strukturell förändring 6-18 år efter avverkning
Today green tree retention, together with leaving dead wood, is a common practice with the aim to reduce negative impacts on biodiversity and environment due to clear-felling. To better understand whether this conservation practice also makes a long-term difference, it is important to know what happens to these trees after harvest. Few studies have made an assessment of what happens to retention trees over a longer time period. In this study I inventoried retention trees that were left at clear-cuts six, twelve and eighteen years ago. I carried out a re-inventory of 57 retention patches (divided into free-standing tree groups, small swamp forests and edge zones) and free standing dead trees, spread over 25 previous clear-cuts in central Sweden.
Hållbar köttproduktion och köttkonsumtion i Dalarna
The release of green house gases and the environmental impacts humans have on the environment are huge and might cause irreversible changes to our earth. Meat is considered to have large impacts on the environment, especially beef meat and therefore there have lately been considerable discussions on the sustainable level of meat consumption and production. The main goal with this thesis is to study sustainable meat production and meat consumption in the county of Dalarna in Sweden. Indicators for sustainable meat production and meat consumption were developed and applied on three cases. Interviews were carried out with a municipality in the region that represents the consumer and three beef farmers that represents the producers.
Hälsokontrollen av den gemensamma jordbrukspolitiken (CAP) : effekter på lantbruket genom gårdsstödet
The Healthcheck is an evaluation of the 2003 years reform of the Common Agricultural Policy (CAP). When the Healthcheck of CAP is decided, most likely in the beginning of 2009, there will be a discussion about how CAP will appear in the next budget period 2013. One main question in the Healthcheck is how the farm support will be designed. A suggestion that has arised is if todays addition amount for dairy- and beef production should be transferred to the fundamental farm support. In this exam theses calculations has been done in created typical farms in every Swedish support region for cereals-, dairy- and beef production.
Translokation av större vattensalamander : -bevarandestrategi eller riskåtgärd?
This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.
Svenska skogsinvesteringar i Baltikum : Omfattning, investeringsmotiv och skogliga skillnader mellanländerna
Uppsatsen beskriver omfattningen av svenska skogsinvesteringar i Estland, Lettlandoch Litauen. Studien kartlägger även de största aktörerna, investeringsmotiv ochsignifikanta skillnader i skogliga förutsättningar i de olika länderna.Eftersom vi inte har funnit tidigare studier av svenska skogsinvesteringar i något avdessa länder, har studien baserats på officiell statistik och faktauppgifter,litteraturstudier, intervjuer, e-postkommunikation, samt information frånwebbplatser. Vi har även genomfört intervjuer i form av en enkät med utvaldaskogsägare.Resultat och analys innehåller en beskrivning av de skogliga parametrarna förrespektive land, en sammanställning av enkätsvar, samt uppgifter omskogsmarkspriser i Baltikum.Baserat på vår uppskattning omfattar de svenska skogsinvesteringarna i Baltikum ca300 000 ha, varav 150 - 200 000 ha i Lettland, ca 100 000 ha i Estland och ca 30 000ha i Litauen. Detta motsvarar ca 4 % av skogsarealen i Baltikum.Bland skogsbolagen är de största aktörerna Bergvik Skog, Södra Skogsägarna,Tornator och Skogssällskapet som totalt äger 115 000 ha. Bland investeringsfondernaär SPP & Storebrand och Europeiska Skogsfonden störst och blandprivatpersoner/företag är t.ex.
Rom II:s inverkan på lagvalet vid fartygskollisioner
I januari 2009 trädde en gemenskapsrättlig förordning i kraft som reglerar tillämplig lag vid utomobligatoriskt skadestånd, den s.k. Rom II-förordningen. Inom ramen för denna uppsats analyseras hur Rom II påverkar lagvalet vid sjörättliga tvister och särskilt vid fartygskollisioner.Enligt huvudregeln i artikel 4 (1) Rom II stadgas att lagen i den stat där den direkta skadan uppkommer skall tillämpas på tvisten. Bestämmelsen innehåller två undantag, dels artikel 4 (2) som stadgar lagen i det land där skadelidande och skadevållare har sin vistelseort, dels artikel 4 (3) med ett allmänt undantag för det fall det finns en uppenbart närmare anknytning till ett annat land.Enligt tidigare sjörättspraxis hade flaggans lag en central betydelse vid lagvalet. I och med att artikel 4 (2) pekar ut lagen i det land där skadelidande och skadevållare har sin vistelseort, vilket rörande juridiska personer förtydligas i artikel 23, blir platsen för den centrala förvaltningen avgörande.
Kulturella skillnader mellan Sverige och Thailand - hur svenska medarbetare i en svensk organisation i Thailand upplever kulturella skillnader
Idag kämpar företag för att överleva på den hårt konkurrerande marknaden och den ökade globaliseringen har gjort att många företag väljer att söka lyckan i ett annat land. Flera företag väljer idag att lägga hela eller delar av sin verksamhet i andra länder. I och med en etablering i ett främmande land kommer företaget att möta en helt ny och främmande kultur och nya affärsbeteenden. Kulturskillnader kan vara ett centralt problem som kan ställa till med svårigheter för företaget och de anställda. Syftet med denna undersökning var att få en ökad förståelse för hur svenska medarbetare i en svensk organisation i Thailand upplever eventuella kulturskillnader mellan Sverige och Thailand.
Neutralitet under kallt krig : En jämförande studie om alliansfriheten, västsamarbete och flygoperativa förberedelser, med tonvikt på åren 1949-1969
Sverige befann sig i en tid där andra världskriget fortfarande var i färskt minne. Geografiskt ligger landet centralt placerad mellan två supermakter, och det råder en spänd stämning i det internationella säkerhetspolitiska läget. Det svenska luftrummet har en stor strategisk betydelse i en internationell kontext. Med förtroendeskapande löften om alliansfrihet och ett avskräckande initiativ i form en av världens starkaste flygvapen försöker Sverige hålla sig utanför eventuella väpnade konflikter. Alliansfrihet syftande till neutralitet i krig är den officiella säkerhetspolitiska ställning Sverige har haft i nästan 200 år, och inte minst under två världskrig.
Bullertunneln : En utredning kring en ny bullerlösning vid trafikleder
The purpose of this Master Thesis has been to investigate the possibilities for a new type of noise reduction solution that could decrease the negative effects resulting from larger traffic roads. The idea has been to construct a noise barrier with a roof ? like a tunnel placed on a road. The choice of material has been focused on transparent materials in order to lower visual intrusion and barrier effects. This project idea is called the Noise tunnel.After having investigated the current offer of noise solutions, it has been concluded that these solutions rarely provide a sufficient level of noise reduction ? at least not when government regulations of acceptable noise levels are applied.
Att dela perspektiv på marken : om kommunikation mellan naturreservatshandläggare och berörda markägare
How do the administrators of nature reserves experience the communication with the land owners concerned? The article is a qualitative study within the environmental communication subject. The study has been performed through qualitative interviews with administrators of nature reserves. Being in action the administrators must know how to communicate with people. The result of the study shows the administrators lack a language to describe their experience of the communication with the landowners.

Planseparerad spårtrafik i Göteborg
The City of Gothenburg has an urgent need to upgrade its public transport. The capacity of its light rail transit (LRT) has reached maximum capacity within the inner city limits years ago. The construction of an underground metro will be very expensive and time consuming due to the soft clay beneath the city. The apparent need of developing another type of mass rapid transit (MRT) is urgent. An elevated metro have turned out to be a success in Greater Vancouver, but is it possible for the system to operate well in Gothenburg with its narrow streets and current land use; will its route coexist with the current LRT or will the noise disturb people too much?.
Environmental impact assessment of energy recovery from food waste in Singapore : comparing biogas production to incineration
As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.
Att uppleva naturen med alla sina sinnen : Hur undersöker och upplever förskolebarnen naturen?
AbstractThis project discusses various aspects of children's way to explore nature with their senses. Therefore I conducted a study in two preschools, one nature-oriented and another preschool. This study was carriedout usien the three metods, interviews, observations and surveys. Interview four children from each preschool, observations of each group outdoors during four different occasions and question forms to teachers. The result of the study showed that both teachers and children have a great interest in being outdoors in nature, but it is not always possible to take out all children's groups. The reason is large groups and inadequate staff.
Identifiering av fosfatfosfors käll- och flödesfördelning i ett litet jordbruksområde
Eutrophication of lakes and streams are nowadays a well known environmental problem and implies an enrichment of the nutrients phosphorus (P) and nitrogen (N). Phosphorus is considered to be the most important component for the growth of aquatic plants and leads in too large quantities to an intensification of growth. Phosphate (PO4) is the fraction of phosphorus that can easiest be taken up by plants and thus have the greatest impact on eutrophication. Increased plant growth in lakes and unfavorable conditions for aquatic animals are two examples of negative consequences. A significant portion of the increased nutrient supply to nearby water can be derived to phosphate leaching from agricultural areas, where private sewers and agriculture is two main sources.
Miljökompensation vid exploatering av Natura 2000 : en jämförande studie av Sverige, Tyskland och Nederländerna
The purpose of the thesis is to describe how environmental compensation is carried through when it comes to exploitation of Natura 2000. The thesis also relates to the three theories of planning synoptic, advocacy and transactive. Three cases of environmental compensation have been studied from three different countries where an exploitation of the Natura 2000 is done. Sweden, Germany and the Netherlands have all been working with environmental impact assessments as a demand to be able to carry through their projects. The projects concern the development of a railway track, an industry and a port which all have been approved by the EU-commission to carry on because of socioeconomic reasons.
