Hedging Core and Non-Core Risks: Evidence from Forestry and Paper Industry
A great number of empirical researches show that hedging is associated with higher firm value, particularly hedging interest rate and exchange rate. However, there is no clear support for value-added risk management hypothesis in the case of producers of commodities. Moreover, according to Shrand and Unal (1997), there are two types of risks, core business risks (or core risk) and homogeneous risks (or non core risks), which are based on a firm's comparative advantages with respects to the source of risk. Firm can earn economic profits for bearing core risks in which it has a comparative information advantage. Firm earn a zero economic rents for bearing non-core risks, where it has no advantage information than its competitors.
Utvärdering av effekter hos deltagare i projektet Skogsbruk och vatten inom Landsbygdsprogrammet hos Skogsstyrelsen i Östergötland
Som skoglig sektorsmyndighet är det Skogsstyrelsens uppgift att omsätta regeringens skogspolitiska mål i praktiken. De behöver därför ha kunskap om deras arbete faktiskt ger effekter i skogsbruket. Ett verktyg för att undersöka effekter är utvärderingar. Genom en utvärdering kan Skogsstyrelsen se vilka effekterna är samt få ett underlag till att förändra och utveckla framtida projekt. Denna studie syftade till att utvärdera effekter hos deltagare avseende kunskapsinhämtning och användningsgrad samt deltagarnas upplevelse av vattenkvällarna i projektet Skogsbruk och vatten inom Landsbygdsprogrammet hos Skogsstyrelsen i Östergötland.
Anpassad skötsel - exempel på hyggesfritt skogsbruk i Mellannorrland :
Total protection is often the option chosen when protecting forests with high environmental values. An alternative to total protection is application of management regimes that do not interrupt continuity of tree cover. This study focuses mainly on continuous cover forestry (CCF) in forest stands already protected. All objects are situated in the county of Jämtland in northwest Sweden.
The purpose of the study was to attain a greater knowledge about CCF practices.
Klassning av renbete med hjälp av ståndortsboniteringens vegetationstypsindelning :
During thousands of years, reindeer have adapted to living under harsh conditions with large seasonal variations in climate and forage availability. This adaptation implies that body functions and nourishment needs are strongly bound to the season. In the summer the reindeer has to maximize food intake to build up fat and protein reserves for the winter. More than 200 different plant species are included in the reindeer diet, but since reindeer have an unique ability to use the nourishment in lichen, different lichen species make up a large portion of their winter diet in many areas. Fundamental for reindeer husbandry is access to natural grazing during most of the year.
Ifrågavarande kronopark skall benämnas Skatan : en skogshistorisk analys av Ekoparken Skatan
People have utilised and influenced the boreal forest for many centuries. Prior to the industrial revolution during the 19th century, however, human use primarily only had a low impact on the forest. When the timberfrontier swept over the country, the Swedish forests came to change for ever. The study site for this thesis is situated in the northern part of the county of Västerbotten, Sweden, and has previously been a National forest. Today the area is an ecopark and the land is owned by the forest company Sveaskog.

Skogsbrukets erfarenheter av Poppel Populus sp. i Skåne :
In Europe poplar plantations has been planted for more than one hundred years. In the first plantation was made in 1940. The interest for poplars has since then shifted over the years and has for long periods been very low but is now slowly increasing again. The main reasons why poplars are becoming more interesting are because of their great production potential. Nevertheless, the knowledge of how to mange poplars in Sweden are very low and very little research has been done concerning management of the species.
The objective for this study was to; 1) investigate and document experience and results obtained in practical Swedish forestry, 2) to give a fair picture of the perceived advantages and disadvantages that the poplars has for the forestry, 3) document what the foresters that has experience and those who has no experience of poplar plantations thinks about the potential of poplars.
Vi tar tempen på ert CO2-utsläpp! : en studie av hållbarhetsredovisningars användbarhet
The environment has become an important part in people´s lives, and in today´s society stakeholders demands have increased upon companies when it comes to sustainability reports. How these sustainability reports are designed depends on whom it?s for, laws and regulations, and the companies own norms and values. The purpose of sustainability reports is to measure, monitor and compare a company´s enviromental impact. It?s not only about integrating economics, but also enviromental and social standards together to get both financial and competitive advantages.Sustainable Value method is a new model and is the first real method that can be used to evaluate a company´s resources, both financial, social and enviromental to a sustainable value.This model is used to compare the resource efficiency between companies.In this thesis, a documentary study with an experimental approach has been made.Sustainability reports from six selected companies (in the engineering and forestry sector) have been investigated with respect to their accounting for carbon dioxide, and an experiment using the method ?Sustainable Value Approach? was subsequently performed.
Naturhänsyn vid föryngringsavverkningar : En jämförelse mellan certifierade och o-certifierade hyggen
A growing number of Swedish forest owners are choosing to certify their forestry. However, there appears to be a lack of field surveys which describe differences between certified and non-certified forests concerning the degree of completed environmental considerations. In order to know to what extent certified forests contribute towards improved environmental consideration, we need studies on how large the difference is in relation to non-certified forests.Differences between certified and non-certified forest clearings were quantified through an inventory of the number of retention trees, dead trees and snags. The result showed that the retained number of the investigated parameters varied greatly between individual clearings, regardless of certification status. However, the results suggested that the certified clearings had an average higher incidence ofthe investigated parameters.
Skogen - vårt biologiska kulturarv
This article deals with the woodlands as a biological cultural heritage and how it is taken care of in the protected woodlands in Skåne, in the south of Sweden, especially the deciduous trees which is dominated by beech. High biological values have emerged as a result of grazing and different kinds of forestry. The protected woodlands have been ripped of its cultural influences which changes the biological values on which the original reasons for protection was founded..

Naturhänsynen i FSC-standarden : vetenskap eller gissningar?
The Swedish FSC standard (Forest Stewardship Council) is a level standard used to certify forestry. All the major Swedish forest companies are using the FSC standard, and approximately 50% of the Swedish forests are FSC certified today. In the essay six items within the chapter on environmental issues and biodiversity are examined: the proportion of protected forest, the proportion of annually burnt clear-cut stands, the number of trees with large diameter, the amount of dead wood, the proportion of deciduous trees within a stand and the proportion of deciduous-dominated stands. The FSC standard states a level for all items, and the purpose of the essay is to analyse whether these levels are supported by research within the field of conservation biology. The validity of the levels of the six items is them discussed to evaluate whether changes are required to the next revision of the FSC standard.
