Skiljer sig riskuppfattning och riskhantering mellan kvinnliga och manliga privata skogsägare? : en enkätundersökning bland privata skogsägare i Sverige
As a forest owner you always have to consider hazards and uncertainty when planning your forestry actions. The aim with this report is to test my hypothesis that there is an overall difference between men and women when it comes to perception, estimation and management of hazards/risks in forestry. I will look into if there are differences in how men and women estimate risks in production forestry from an economical point of view. The aim is also to look into if there are differences between male and female private forest owners, in how they perceive and manage hazards in connection with a possible climate change.
To fulfil this aim, an inquiry survey was undertaken in three different areas of Sweden, two areas in the south and one in the north. But in this report I have evaluated the three areas as a whole.
Skogstillståndet och dess förändring i naturreservatet Lindbergska ytan i Mariestads kommun :
The aim of the study is to describe the state of the forest and changes in the Lindberg nature reserve. The study area is a nature reserve with an old coniferous forest, which has not been touched since 1950. The pines in the area have a very big diameter and are 150 ? 200 years old. The spruces are up to 150 years old.
Trakthyggesfria skogsbrukssätt : kunskap, förutsättningar och attityder
Forestry has three main aspects to take into consideration today; economical, ecological and socio-cultural. In order to reach the broad policy goals for sustainable forest management, an increased variety of management approaches are requested. Today clear-cutting is the only method used in 96 % of the managed forests in Sweden. The Swedish National Board of Forestry has therefore initiated a project in order to investigate and develop Continuous Cover Forestry (CFF). This study is a part of this project.
Zenbuddhistiska meditationsträdgårdar - för ökat välbefinnande i Sverige
This paper is intended to provide a picture of which associations water can wake in the human
mind from the perspectives of garden history as well as from that of environmental
psychology. I hope to paint a fairly broad picture of our perception of water that can serve as a
basis for discussion and as a starting point for different forms of design work in landscape
architecture. The historical perspective emphasizes the importance of water as a condition for
the emergence of gardens and in a wider perspective the importance of water in early cultures.
Also, I describe a picture of how water has been used throughout the history of gardens from
early Egypt to the baroque era. The garden history analyzed from an art historical perspective
gives a picture of human associations to water, and the history behind these associations is
presented. As a compliment to the art history approach, I have chosen to highlight our
associations with water from the perspectives of environmental psychology and evolutionary
science.
Viktiga egenskaper hos framgångsrika svenska skolskogar :
A substantial part of the Swedish outdoor education is being practiced in so called ?school forests?. The concept school forest was first introduced in the 1980?s by the organization Skogen i Skolan. The definition of a school forest is an area that is being used for educational purposes, over which the school and the land owner has reached an agreement of how the school may utilize it.
Felbegreppets tillämpning på skogsplantor
Uppsatsen behandlar felbegreppets tillämpning på skogsplantor. Lagstiftningen inom området skog och skogsplantor är relativt omfattande men skogsplantor är biologiska produkter varför lagstiftning inte helt kan förhindra att skador eller sjukdomar ändå uppstår. Det är helt enkelt inte möjligt att framställa skogplantor utan att en viss andel av dem är behäftade med fel. Då det är en mängd sammanverkande faktorer som kan bidra till skador eller plantors död kan det vara svårt att fastställa om orsaken till skadan/plantdöden var att hänföra till plantorna eller faktorer i uppväxtmiljön. Svårigheter att fastställa orsaken kommer därför bidra till svårigheter för skogsägarna i samband med reklamation.
Data och metodik för utbytesberäkning - en studie på Medelpads Skogsförvaltning
To manage the industry?s need of wood assortments in a optimal and cost effective way the forest companies need to have knowledge of the actual standing volume and the yield of the planned clear cuts. The mean volume of the trunk is also important since it is important for the contractors prices. Today the total volume are estimated either with Näslund (1940) or Brandels (1990) functions of volumes, and the yield is estimated with Rune Ollas (1980) function for trunks and stands. The purpose of this study has been to answer the following questions: How good is the yield forecast with data collected with currently used methods? How well can the yield forecasts became with data collected according to the instructions? How well can the yield forecast be with data collected according to the instruction and calculated with the program Aptan for theoretical bucking? The study has been initiated and financed by SCA Skog AB.The material consisted of a number of randomly selected objects ready for clear cut.
Gödslingsstrategins inverkan på Holmen Skog, Umeå distrikt
This thesis analyzes the effects of different fertilization strategies on forest management at Holmen Skog in Umeå district. Harvesting volumes, net present values and fertilization intensity are presented for each fertilization scenario. The planning reserve (percentage area older than minimum final felling age) was also analyzed in this study.The thesis covers the analysis of five different fertilization scenarios, varying in fertilization intensity, from no fertilization at all, to fertilization at every harvesting operation (thinning or final felling). A sub-study was also carried out so the reader in detail can see how the different fertilization scenarios affect individual forest stands of different nature. The analysis has been done with the planning tool PlanWise, which is an application of the Heureka analysis and planning system.
Vet skolelever mer om Stalins skräckvälde idag än tidigare? : En kvalitativ läromedelsanalys om hur beskrivningar av Stalins terror förändrats i svenska läroböcker i historia från 1950-talet till idag
The purpose of this essay is to examine whether the descriptions of Stalin's terror in history textbooks for high school changed from the 1950s until the 2010s. Since previous research shows that textbook content is influenced from different directions and that it dominates in teaching, therefore I want to find out what similarities and differences that exist in the textbooks. The survey is based on a qualitative approach because I want to have a profound picture of the descriptions of Stalin's terror. The results of the survey show that the number of casualties and the descriptions on the famine has changed over time. Furthermore, textbooks also found it difficult to distinguish between terror, politics and ideology.

Beslutsunderlag för energianpassade gallringar i Västerbotten
The demand for renewable energy is increasing in Sweden. This consequently increases the pressure for and willingness to pay for forest fuels. One method to extract forest fuel from suitable commercial thinnings is the "long top method? (LT-method). With this method saw logs and non-delimbed tops are recovered, i.e.
Köp av skogsfastighet : en fallstudie
The price of Swedish forest properties has gone up by 77 percent during the past five years. Amongst private forest managers the high price level signals optimism and confidence for the future.
Many forest owners manage large capital in the forest and a planned economy is to a larger extent demanded to achieve a positive economic result. Forest is long-term and to maximize a single year without planning for the years to come results in less optimization of the parameters available to achieve a favourable economic result.
This case study investigates the investment of two forest properties situated in Götaland.
The management of the forest has been planned for both properties during a period of ten years.
Local forest governance and benefit sharing from reduced emissions from deforestation and forest degradation (REDD) : case study from Burkina Faso
Africa is one of the regions most affected by climate change. However its forests are important carbon sinks for the whole world, and if recognised as a global public good, could be conserved and contribute to green house gas emission reductions. A global mechanism, Reduced Emissions from Deforestation and forest Degradation(REDD+) aims to help developing countries in reducing emissions from deforestation and forest degradation, and enhancement of carbon stocks. REDD+ strategies may, however exclude local forest dependent communities from forests in order to conserve and maximise carbon stocks, thus having a severe impact on local livelihoods. Therefore, how local communities can participate and share benefits from REDD+ is a key concern.This study investigates how three forest dependent communities in the Nazinon forest, in Southwest Burkina Faso could financially benefit from a REDD+ project.
Facklitteratur för barn ? ett försök till analysmodell
This thesis is about how to criticize the large number of non-fiction for children which is published nowadays. I have noticed that both librarians and teachers do not know what perspective to apply with regard to this category of books. There are some good ones, but also a lot of bad ones and some really bad ones. The purpose of this essay is to search by means of criteria from history of art, history of literature ? principally history of children's literature ? and pedagogy, for prevalent attitudes towards non-fiction for children.
Historiebruk : exemplet Judisk Krönika
The purpose of this examination is to investigate how Judisk Krönika, a periodical which was introduced in 1932 with the aim of disseminating Jewish culture and tradition in Sweden, uses history to make comments about its role in contemporary history, specifically during the first two years of the First Intifada. A second purpose was to examine how this use of history differed from results shown in earlier studies comprising the 1960s and the 2000s. The method in use is qualitative; the source material has been read thoroughly and scrutinized in search of the authors open and hidden messages and intentions. The main finding shows that four major themes could be identified: anti-Semitism(anti-Zionism); memory; ethnonational and media. The most dominant theme during the 1980s, as opposed to the 1960s and the 2000s focus on Zionism and Jewish culture respectively, is memory, that could be described as hegemonic and as a part of a existential use of history, which aims for survival and preservation of the Jewish culture in times of conflict..
