Vill du vara med?: En studie av Piteåpanelen och dess inverkan på Piteå kommuns miljöpolitik

The representative democracy has become weakened during the last decades. At the same time the United Nations declared at the Rio de Janeiro meeting in 1992 that environmental problems can best be solved by involvement of all concerned citizens in decision-making. The main purpose of this study has been to examine if citizens panels is a possible way to involve citizens in environmental decision-making and what the outcomes can be. Furthermore the study has investigated what the participation has contributed to environmental politics and how representative the results have been. This has been carried out by investigating the Piteåpanel in the municipality of Piteå by conducting interviews.The result of the study shows that the involvement of the citizens in the decision-making influenced the environmental politics of the municipality.

Vegetationsutveckling och brandhistorik i Tyresta under 9000 år : en pollenanalytisk studie av en skvattramtallmyr i Tyresta nationalpark, Södermanland

Analyses of pollen and charcoal in peat cores, together with age-structure data of Pinus sylvestris from a Ledum-Pinus-mire in the Tyresta National Park (south-east Sweden) show the regional vegetation succession and fire history over the last 9000 years. Five major stages of mire development are identified: 1. Lake (c 7000-6400 cal BC); 2. Wet fen (c 6400-6000 cal BC); 3. Deciduous fen (c 6000 cal BC to c cal AD 700); 4.

Omkonstruktion av kolvlod : På uppdrag av institutionen för geologiska vetenskaper Stockholms universitet

On ocean beds around the world sinking particles of residual biomass from animals and vegetation have, over time, accumulated into thick layers of sediment. For researchers these layers of sediment contain valuable information about the earth?s past climate, information that can be used to predict future climate change and to estimate natural vs. human causes of today?s global warming.The Institute of Geosciences at Stockholm University studies sediment cores that have been acquired with an apparatus called piston corer.

Samband mellan luftföroreningar och klimatfaktorer - en statistisk unersökning

That air pollutants of different kind has impact on our climate can hardly haveavoided anyone during the past years environment explosion in the media. But howis it actually with the reverse, i. e. the climate's impact on air pollutants? The aimwith our degree thesis is to try to find out if different weather factors, statisticallyseen, promotes atmospheric pollutants and particles in the air and vice versa.We got access to data on air pollutants and weather factors that was registeredduring year 2007 at Femmanhusets air pollutant and weather station in Gothenburg.In order to do a statistical investigation of these data, and to be able to analyze if itoccurs relations of various kind, we used the statistics program SPSS.

Den globala uppvärmningen : vad kommer att hända med morgondagens värld?

Mankind faces a serious threat. Its activities, for example the burning of fossil fuels, have led to an enhancement of the greenhouse effect - something that has given rise to a global warming. The climate is becoming warmer, a change that has important effects on the nature as well as for humans and their society. Sea level rising, extreme temperatures are becoming more common, glaciers and other ice caps melt and storms becomes more intense when they appear. The main cause is the emission of greenhouse gases into the atmosphere - carbon dioxide in particular.

Skillnader i kungsörnens (Aquila chrysaetos) flyttningsmönster beroende på ålder och klimatfaktorer : En studie för skyddet av kungsörn

This study examines the factors that influence the seasonal movements of Golden Eagles (Aquila chrysaetos), and can thus provide important information that helps to improve the protection of the species. There were two main purposes of this study. First, I wanted to analyze the difference between preferences of juvenile and adult Golden Eagles in their choice of southern or northern hibernation areas. Do younger eagles prefer moving longer distance to southern areas of Sweden? Second, I wanted to investigate how the climate influenced the choice of date of migration in the fall.

Contortatallens odlingsvärde i Götaland

The third most common conifer in Sweden is Pinus contorta (lodgepole pine). It originates from the western part of North America and was brought here in the end of the 1920s. The lodgepole pine is today allowed for commercial plantations in central and northern Sweden, excluding high altitude locations. Since 1979 only plantations with scientific purpose are allowed in south-central and south Sweden. This document is focused on how lodgepole pine manage perform compared with Pinus sylvestris (Scots pine) in the southernmost part of Sweden, Götaland. The idea came from the fact that the Swedish government is evaluating a notification from the National Forest Agency that suggests lodgepole pine to be allowed for commercial plantation even in southern Sweden.

Thuja plicata - etableringsförsök av jättetuja med fyra olika provenienser

Future climate changes may lead to an interest of alternative and foreign forest tree species in order to spread the risks in forestry. Douglas fir, Sitka spruce, Freemont cottonwood and hybrid aspen are examples of popular foreign tree species that along with western red cedar could have a future in the Swedish forests.Södra Skogsägarna and SLU have collaboration in establishment of foreign species in Swedish forests.The purpose of this study was to analyze and present the establishment of western red cedar, and to survey and illustrate injuries of freeze drying and other damages like deer browsing, vegetation and insect attacks. The study included four different provenances, and spruce as a reference, planted in two locations ? Asa and Släne.Western red cedar is despite its name a conifer of the cupressaceae family with defined secondary characteristic and gets along well with an overstory. Western red cedar grows often in mixed stands with similar conifers and its natural habitat is within and in the area near to British Columbia.The study included two series of field inventories, one made in the summer and one in the autumn 2013, three growing seasons after plantation.

Hur en ökad marktemperatur påverkar fotosyntes och markrespiration i en boreal skog

During the year of 2008, a powerful earthquake hit the southern part of Iceland, which changed the geothermal conditions in the area around the city of Hveragerdi. Elevated soil temperatures in a nearby forest plantation have contributed to a unique opportunity for researchers to study how an increased soil temperature affects the boreal forest ecosystem, something that partly can be connected to the climate changes which are happening today. The boreal forest is representing a carbon sink and a buffert for the emissions that occurs. Changes in this ecosystem will for that reason contribute to major impact for the global carbon cycle. To study the impact of how elevated soil temperatures affects different processes in a plantation of Sitka spruce, studies were made on the photosynthesis of the trees and the respiration from the soil.

Biobränsle från det jämtländska jordbruket : en studie om lantbrukarnas alternativkostnader vid odling av rörflen

The use of fossil fuels such as coal and gas are a contributor to the global warming. The climate change is a worldwide problem with far reaching consequences that is believed to be very expensive. The United Nations has been introducing a framework convention on climate change. One component of the convention is the Kyoto protocol. The protocol is obligating the developed countries to decrease their emissions of greenhouse gases by 5.2 percent during the time period 2008-2012.

Att systematiskt hantera kunskap vid planering av ny infrastruktur : En fallstudie om skyfallsskador på riksväg 90 i Kramfors kommun

Natural disasters are becoming more common due to climate change and it is important to adapt the society and its infrastructure to withstand events such as extreme rainfall. Precipitation is an important climatic factor affecting the transport and annually generates the cost of millions in damages, over the past 40 years heavy rain has increased and will continue to increase in the future. The extreme rainfall that occurred in Kramfors municipality in September 2013 led to flooding and destroyed several roads, including highway 90, which recently both had been rebuilt and given a new stretch of road. Extreme rainfall had also occurred in the municipality earlier.  The aim of the thesis was to examine how the Swedish Transport Administration handles new knowledge gained after natural disasters and how this is used in the planning of new roads.

Beräkning av värmeförluster och energieffektivisering av elbussar

The ?civilized? world is in need of fossil fuel in order to function. Hybricon AB is a company in Umeå that is developing a technology that hopefully can reduce parts of this need. They are currently testing their two electrical busses (with Hybrid backup) in city traffic on the roads of Umeå in cooperation with the county of Umeå.                               The busses are originally diesel-busses, but the diesel motor has been replaced with two electrical hub-motors with a power of 145 kW each that are powered by batteries.The batteries are charged at the end station after each route. In case the batteries should run low on capacity during driving, they can be recharged by the so called genset.

Sensory profiling of Swedish white wines and a contextual analysis of Swedish viticulture

The aim of the study is twofold, to generate a sensory profile of Swedish wine today and to investigate the opinion of both wine producers and wine experts on viticulture in Sweden and wine from grapes grown in Sweden, achieved through a contextual analysis comprising a literature study and interviews with wine producers in Sweden and Denmark and wine experts from Sweden and Germany, and a sensory analysis at the company Ipsos. ?Mixed methods? was the chosen research strategy as the semi-structured interviews gave qualitative results and the sensory analysis would give quantitative results displayed as spider charts. There is a lack of studies investigating how the Swedish wine is perceived by consumers and consumers might be unaware that the Swedish wine, established through ?trial and error?, is increasing in quality every season, creating a need to display the sensory profile of Swedish wine to strengthening the perception of Swedish white wine. This study shows that the Swedish white wine today is a wine with a fresh, citrusy and flowery aroma and a fresh, citrusy and green apple taste, however, a sensory analysis cannot show if the attributes are those that are desired by the customer, a consumer test is necessary to conclude that. Trends point towards locally produced products, one reason why Swedish wine has great potential, yet the future needs to be secured through job opportunities and education. Creating an approval system for Swedish wine is suggested as a future improvement, it is a common procedure in most wine regions.
