Ekoturismens natur- och miljöpåverkan i polarområden
Tourism in the Arctic and Antarctic is increasing rapidly. In both Polar Regions, the cruise tourism is predominant. Several of the tour operators arrange trips under the banner of ecotourism, meaning that the trips should be ecologically sustainable. To ensure ecotourism standards there are different types of certifications; for cruise travels in the Arctic there is AECO (the Association of Arctic Expedition Cruise Operators) certification, and for travels to the Antarctic IAATO (the International Association of Antarctic Tour Operators). Promoters of ecotourism argue that these trips are important because they create support for conservation work among tourists making them ?polar ambassadors?.

Överlevnad och tillväxt för nyplantersade barrots- och täckrotsplantor : en studie av 42 bestånd i södra Sverige
The choice between bare-rooted and containerized seedlings in southern Sweden affects
the investment costs as well as growth and survival. It is important to take these differences
into account when choosing seedling type for reforestation. The most important
differences between the two seedling-types is that bare-rooted seedlings has open root
systems whereas the roots of containerized seedlings are grown in a container which may
contain water and nutrients that are available for the seedling during the first period after
planting. Moreover, bare-rooted seedlings are often older which results in thicker stembase
and better resistance to attacks of pine-weevil (Hylobius abietis).
In order to study differences in survival and growth between bare-rooted and containerized
seedlings a survey study of newly planted clearcuts in south-western Sweden was
made. In the study tree seedling types was included, one bare-rooted and two containerized
with different ages.
The population of pine weevils was probably low during the studied period which
resulted in lower pine-weevil damage than normally found in this area.

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.
Detektor på skördare för utsortering av träd med metallskrot
Fortifikationsverket which is the landlord for the Swedish national defence has a great problem in their forestry due to the relatively large amount of metal objects in their timber. These metal objects cause different types of economical losses in the timber refinement chain. To enable out sorting of logs containing metal objects already in the harvesting phase, Fortifikationsverket is interested of the possibility to utilize some type of metal detector in a harvesting head for that purpose.The goal of this study was to, with help of a case study, enlighten the problem that metal objects in timber cause for Fortifikationsverket and their customers of timber and to investigate conditions of to mount and utilize some kind of metal detector in a harvesting head at present.The saw timber deliveries by Fortifikationsverket during the time period 2003-2005 was used as a reference volume for calculations of economical losses. In this case study was included two sawmills where timber from Fortifikationsverket were delivered to for further refinement. Factors investigated were the type of damage metal objects caused in these two sawmills and the economical signification of these damages.
Miljöpåverkan av bomullsväv för flamskyddade arbetsbyxor

Miljöledning i produktutveckling : En studie i ISO 14001-certifierade företags produktutvecklingsprocesser
Bakgrund: För att underlätta organisationers ansvarstagande gällande miljöpåverkan har standarder införts med syfte att ge stöd i utformning av miljöledningssystem. Ett vida använt verktyg är ISO 14001 vilken framhåller ständiga förbättringar i förhållande till den enskilda organisationens satta miljömål. På grund av standardens generella utformning är det upp till den enskilda organisationen att implementera denna på ett sätt som bäst passar verksamheten. Forskning pekar på att ISO 14001 innehar en ledande roll då det kommer till tillverkande företags miljöengagemang. Dock påvisar forskare att standarden inte är tillräcklig när det kommer till kommersiella produkters miljöpåverkan, men att företag som varit ISO 14001-certifierade en längre tid ändå i stor utsträckning arbetar systematiskt med denna aspekt.Syfte: Syftet med denna studie är att undersöka hur miljöhänsyn utformas och implementeras i ISO 14001-certifierade företags produktutveckling då man utifrån tidigare forskning kan anta att detta innebär organisationsspecifika varianter.Metod: För att uppfylla studiens syfte har fallstudier i fyra svenska företag genomförts.
Vattenfall - I nationens Intresse? : En diskursanalys av den riksdagspolitiska kampen om Vattenfall
Till följd av Vattenfalls uppmärksammade investeringar i fossilbränslebaserad energiverksamhet har vi genom att analysera den riksdagspolitiska debatten kring Vattenfall, sökt efter återkommande yttranden, genom vilka vi konstruerat diskurser som står för vad riksdagspolitiska aktörer anser i frågan om det statliga styret av Vattenfall. Vi kommer fram till att det inte helt oväntat går att skapa två övergripande diskurser, där de olika politiska blocken verkar inom varsin diskurs i frågan om hur Vattenfalls miljöintentioner ska uppnås..
Bildandet av naturreservat : uppföljning och klimatanpassning
AbstractWe are facing a century of rapid change in climate, with significant challenges in managing the impact of changes in living conditions for plants and animals. We can already see the responses of species through changes in phenology and spatial distribution, which may change ecosystem structure and function, with subsequent effect on ecosystem services and biological diversity. In Sweden, between 2005 and 2010, the red-listed species has increased by 13 % and similar trends can be seen across the world, making it difficult to attain national and international environmental objectives of preserving biodiversity. One way to reduce the loss of biodiversity is to protect nature from exploitation by allocating valuable areas as nature reserves, but climate change affects protected areas just as much as other landscapes and therefore requires elaborate systems of protection to facilitate species' survival. The paper has examined how the decisions and management plans for nature reserves in Sweden have been followed-up and whether they are climate adapted or not by examining 30 nature reserves, classified as newly formed (2012), recently revised (2009-2011) and older (1977-2007) reserves, and assessed what is in the decisions and management plans for follow-up, revision, long-term goals and documentation.
Recipientundersökning av Ensjön : Bedömning av sulfidmalmgruvan Enåsens eventuella påverkan på sjöns vattenkvalitet
Ensåsengruvan is a mine situated within Ljusdals municipality in central Sweden. Themine was in use from 1984 to 1991 and has since been undergoing a remediation program. Mine tailings from sulfide rich ore is a potential environmental hazard due to its tendency to cause acid waters and heavy metal leakage. Lake Ensjön is situated one kilometer from the mine area. Due to the hydrological conditions it was not expected to receive inflowing water from the mining area.

Svinnoptimering VTIS1
The goals of this Bachelors? Thesis were to establish the production loss through the VTIS1 Pasteur at Arla Foods Linköping dairy and then suggest simple but effective solutions to minimize the losses for each production run. If the timeframe allowed it, some of the solutions would be implemented and tested in full production to determine their impact on economic and environmental savings.The very first step of this project was to establish the statistics over what losses there is in the production pipeline through VTIS1, from milk and powders in mixer tanks to finished and packed products in cold storage. Then, when knowing how much product was actually lost and where, those bottlenecks could be pinpointed and examined more closely. At this stage the focus was switched, from the otherwise complicated and broad manufacturing process, to the VTIS1-aggregate, since early data indicated there were quite substantial losses there.In conjunction with this project Arla Foods purchased an absorption photometer-measuring device (OPTEK AS16) that could be inserted straight into the product stream out of VTIS1, allowing real time measurements of its optical density.
