Undersökning av sambandet mellan strålningstemperatur och NDVI i Sahel
Several studies have analysed the relationship between Normalised DifferenceVegetation Index (NDVI) and radiative surface temperature. A main goal for moststudies have been to find the best method for carrying out land cover classificationsand to study land cover changes, based on a combination between the twoparameters. Since atmospheric components have a significant influence on bothparameters, most applications were based on multi-temporal data. The quality of theindividual values in such a combination is improved, but the biophysical justificationis uncertain. This study presents a different method, based on only the combination ofvalues that have been registered the same day and about the same time of the day.125 daily images of NDVI and 250 images of radiometric temperature were used inorder to analyse the relationship between (1) NDVI and radiative temperature and (2)NDVI and relative temperature difference between early morning and mid-day.Results between NDVI and radiative temperature show a significant negativecorrelation on areas where a distinct growing season develops, and a strong positivcorrelation where vegetation is abscent throghout the season.
Service-Dominant logic i B2B kontext : Hur skapa mervärde på en eftermarknad
För att på ett effektivt sätt uppnå konkurrensfördelar på dagens marknad krävs det att företag finner nya strategier för att bli konkurrenskraftiga, en strategi är att verka på en eftermarknad. Företagskunder utgör en mindre marknad och beroendet mellan parterna är större (jämfört med privatkunder) påvisar detta att relationen är en viktig del i en B2B-miljö. Service-Dominant logic (S-D logic) beskriver hur ett paradigmskifte sker där kunden betraktas som värdefullt humankapital och företag vinner konkurrensfördelar genom långsiktiga relationer, värdeskapande tillsammans med kund och utbyte av kunskap genom interaktivt processarbete. Syftet med denna studie är att undersöka på vilka sätt företaget Komatsu Forest kan vinna konkurrensfördelar genom att implementera S-D logic. De strategier vi testar är front-line employee (FLE) ? personal med kundkontakt, butikslandskapet, varumärket och den interna kommunikationen.Studien baseras på kvantitativa studier med en kompletterande kvalitativ studie.
Tjäderns (Tetrao urogallus L.) vinterdiet i norra Sverige : är gran (Picea abies) viktig i vissa habitat?
In Scandinavia, capercaillie are often associated with pine trees (Pinus sylvestris) in winter, with pine needles as the main diet. Few dietary studies have been conducted in Sweden and winter diet is subject to little debate. The interesting thing is that this "pine specialist? is also found in spruce (Picea abies) forest habitats where pine is scarce or unavailable. In many studies outside Sweden (primarily Central Europe) spruce is regularly observed in the winter diet, but I have found no reports on the selection of the diet in spruce forest areas in Sweden.
Clover (Trifolium spp) gamefields : forage production, utilization by ungulates and browsing on adjacent forest
Wildlife is a valuable and renewable resource that promotes economical, ecological and social values. These values are important for developing and maintaining many rural societies. However, growing ungulate populations have led to increased browsing pressure on valuable forest trees and crops. Previous studies have proposed supplementary feeding and gamefields as potential methods for controlling the ungulate foraging and reducing browsing damage by providing other attractive food resources. However, quantitative estimates of potential biomass production of various gamefield crops and browsing pressure on the surrounding forest have been lacking.
Chachaklum, a viable initiative? : a stakeholder management approach towards a community enterprise
Due to poorly functioning local and regional markets, the smallholders in San Francisco, Petén, were dependent on intermediaries that took advantage of the smallholder?s distance to markets. In an attempt to secure income and strengthen their bargaining position, 189 smallholders joined forces through the creation of a social smallholder network, held together by a community based enterprise. This enterprise was initiated in 2011 with the help of government incentive programmes and NGOs that within a few years will leave the enterprise to auto regime.
This study treats the sustainability of a community forest based enterprise, Chachaklum, in northern Guatemala. The study identifies factors that enable smallholders to organize themselves in order to obtain business practices that support an improved standard of living.
Skiktning och strukturell utveckling i unga naturlika skogsplanteringar: :
Multilayered woodland types are an important part of the urban forest. The knowledge how to establish and maintain such plantations are not as deep as other knowledge fields concerning forestry. Therefore this study has looked upon how to achieve multilayered structures in young nature-like woodland plantations. As a theoretical base for the study three different major knowledge culture have been studied that concerns the subject, ecology, forestry and landscape management/design. This three theoretical framework concludes that many natural processes strive in the opposite direction of multilayered structures in their youth.
Skogsvårdsentreprenörers uppfattning om SÖDRA som uppdragsgivare
Södra in Oskarström has the ambition to become the best client for silviculture contractors and another aim is that the contractors should feel a strong sense of community with Södra. Several factors play an important role in order for these ambitions to be realized. The purpose of this study was to investigate how the contractors feel about their business relationship with Södra. The study was conducted during the spring of 2015 through a questionnaire which was sent to all ten silviculture contractors working with Södra in Oskarström. Overall, it seemed like the contractors were satisfied with the collaboration.
Jordlöparfaunan i bestånd av contortatall (Pinus contorta) och svensk tall (P. sylvestris) 1987 och 2010
In the 1970´s the North American lodgepole pine (Pinus contorta) was introduced to Sweden in large scale. The lodgepole pine affects its new environment different from Scots pine (P. sylvestris), leading to a change in biological diversity.
Forestry today affects the ground beetle fauna (Carabidae). Habitat specialists associated with older forests are first affected. When the canopy closes again after a clear-cutting species that prefer open habitats reduces and those who prefer mature/closed forests increase.
In this study we compare differences in diversity and community structure of ground beetles in stands of lodgepole pine and Scots pine.
Krishantering i förskolan
Detta examensarbete visar att upplösande av samägande av fast egendom är viktigt då ägandet av fast egendom är kopplat till rättigheter såväl som skyldigheter. Det är av mycket stor vikt att ägande och brukande av skogsfastigheter fungerar och att det finns förutsättningar för att lyckas med det. Dock kan samägandet i vissa situationer hindra utvecklingen av fastigheten. Skogsbruket är en viktig inkomstkälla för den private skogsägaren såväl som för Sverige, skogsbruket i vårt land stod 2010 för 7 % av världens totala export. Även om Sverige är ett litet land i världen, är det inte obetydligt inom skogsbranschen.
Biotopskydd av stenmurar : Skäl för dispens
Stone walls in agricultural land are incorporated in the general protection of biotopes. They are protected because they provide a habitat for endangered species. Therefore it is illegal to carry out proceedings in an area that is included in the protection of biotopes. In order to do that, exemption is needed which can only be granted if there are special reasons. The essay stipulates what these special reasons are.In an exemption errand the interest for nature conservation must be weighed against a public or a private interest.
Från det livskraftiga lantbruket till det olönsamma : en studie av skäl till minskad verksamhetsomfattning och varför man bor kvar
This essay is a study that contributes to the larger research question ?Why do farms shut down?? The subject was chosen because it is a relevant problem that needs to be studied more. This study's boundary is to investigate the reasons for decisions leading to the farms at the Torstuna community, Fjärdhundra, changes in any activity scale or the outlook of the entire farm. When a decision is made, there are usually several reasons behind it and it is these reasons which this essay is aiming to study. The question "What are the reasons for the elderly to live on the farm even though the farm is not cultivated by them?" is also covered in the study.
Fiskarebönder och landskapet i Karlshamns skärgård förr och nu
Hällaryd archipelago, consisiting of approx. 50 islands, islets and skerries, is situated east of Karlshamn city in Blekinge province. The archipelago has been shaped into a rift valley by volcanic activity, the inland ice and maritime climate.The archipelago is divided into seven main islands: Bockö, Västra Bokö, Ekö, Hallö, Joggesö, Mjöö and Tärnö. This essay will connect population changes with land use.
Linderödsgrisen : en inventering av populationsstruktur och produktionsnivå
In 1993, Sweden signed the Convention on Biological Diversity and thus agreed to conserve our indigenous biological diversity. As a part of the convention, Sweden is obliged to conserve a number of domestic animal breeds and among them the Linderöd pig. In 1952, the zoo, Skånes Djurpark, took care of a pregnant sow that was regarded to be related to the old "forest pig". The old forest pig was thought to have been extinguished by the early 20th century as a result of the ban on boars not approved by state inspectors. However, according to later accounts, several farmers still kept some of these non-approved pigs.

Äldre kvinnor från forna Jugoslavien och deras aktiviteter i dagligt liv
Att vara en äldre invandrare i ett nytt land kan påverka erfarenheten och åtagandet i människors vardagliga aktiviteter. Det är ett flertal olika faktorer som påverkar delaktigheten av aktiviteter i det dagliga livet. Förändringar i det vardagliga livet kan leda till att aktiviteter, struktur, syfte och motivation förändras eller till och med försvinner. Studiens syfte var att beskriva aktiviteter i dagligt liv hos äldre invandrarkvinnor från forna Jugoslavien men även att beskriva vad som motiverar dem att utföra de aktiviteter som de gör.Till studien valdes en kvantitativ design med kvalitativa inslag eftersom den baserades på ett strukturerat intervjuformulär med två tilläggsfrågor. Studiens resultat visade att ett flertal deltagare har förändrat sina dagliga aktiviteter och att saknad efter den sociala gemenskapen har medfört ett mer inaktivt liv.
