Even though Sweden is a small country which has a low rate of inhabitants is it one of the worlds leading nations of exporting products from the forest industries. The Importance of a sustainable use of the Swedish forests has been known for many years. In 1903 the first law of forestry were establish. Today the National Board of Forestry carry out inventories of regeneration result. The result of the latest inventory showed that especially the non-industrial private forest owners did not full fill the regeneration work after a clear cut.

In January 2005 large forest areas in south Sweden were severely damaged by storm. This final thesis describes the work with creating an ecological and landscape-adapted regeneration plan for a severely storm damaged property in Kronobergs region in south Sweden. This regeneration plan, in difference to more regular plans, are focusing more on the owner?s use and goal?s for the property and seeing the property from a more comprehensive view in the regeneration process. Beside production and environmental values the plan also take in consideration other values as aesthetic, culture history, landscape picture and recreation values.

As the past century?s technological development has progressed the Swedish boreal forests have transformed into dense, highly productive, homogenous and coniferous forests. The area around Saxdalen in Ludvika municipality has long been dominated forests which have been heavily worked since the 18th century. There are in Ludvika 119 000 hectares of productive forest land. Around 70 percent are owned by forest companies and 20 by private forest owners.

The freshwater pearl mussel (Margaritifera margaritifera) is threatened throughout its range. There has been a substantial decline of the species and one major reason is habitat degradation. We investigated how the substrate composition of the bottom floor affects the regeneration of the mussel by analyzing data from the Västerbotten County Board?s inventory of the freshwater pearl mussel. The results implied that fine material such as fine sediment and sand might be detrimental to regeneration whereas gravel and boulders and in particular stone seem to be beneficial.

In the tropics, logging and wild fire can result in degraded secondary forests with lower biodiversity than in the natural forest. One way to limit forest degradation is to rehabilitate the present large areas of secondary forests. However, there is a lack of knowledge concerning the ecology of tropical tree species and further studies would be advantageous for future rehabilitation efforts of degraded rainforest. The objective of this study was to investigate how mother trees in secondary forest and different site factors affect the abundance and spatial distribution of natural regeneration of non-pioneer tree species in a tropical rainforest in Sabah, Malaysia. The study took place in the INIKEA Forest Rehabilitation Project area, which suffered from wild fire in 1983 and has been selectively logged over both before and after the fire. Natural regeneration and site variables were inventoried in plots, while mother trees were inventoried in the whole survey area.

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

The purpose of this study is to describe the All inclusive concept and to what extent it can be described as sustainable from economic, social and environmental aspects. The empirical study is based mainly on qualitative interviews with four respondents. Two of the informants find the All inclusive concept to be sustainable while the other two are critical to the concept. In the discussion the essay writers argues around the empirical results of the study and how the All inclusive concept possibly could become sustainable. To consider the All Inclusive concept to be sustainable, it is important that the economic, social and environmental aspects are integrated with each other at the destination..

Environmental issues and sustainable development is a high priority in today?s society and has received substantial attention lately. In the inaugural speech it is expressed that the goal for the IT?politics is a sustainable information society for everyone, which can be achieved by using IT to support sustainable growth. The Ministry of Enterprise, Energy and Communications has developed a document which outlines three specific proposals on what the government should focus on during a three?year period (2008?2010) that with the use of IT will contribute to a sustainable society.

The design of buildings is today considered to be crucial for obtaining sustainable development. Research concerning sustainable building is considered to be a Swedish area of strength and development projects as Hammarby Sjöstad and Bo01 are often pointed out as Swedish prime examples of sustainable building. Some still argue though, that that these projects should not be presented as sustainable, due to its incompetence to meet their objectives. This contradiction has attracted my curiosity. By doing this study I hope to gain understanding about the difficulties Bo01 and Hammarby Sjöstad are surrounded with and its significance for sustainable development.

In this study environmental work in the Swedish hotel chain "Scandic" is investigated. Earlier studies point out sustainability and different environmental certificate programs as essential for the housing sector to contribute to sustainable tourism. The purpose and willingness to fulfill such a mission has been investigated by interviewing central actors in the hotel chain. The result shows that there is a desire to be part of environmental certificate programs mainly for the reason to be part of the system and not for the benefit of nature. Sustainable development is understood as being environmentally friendly. Different solutions to adapt and being more environmentally friendly is discussed.

This thesis concerns how local governments use the concept sustainable development, and what the concept means. The concept of Agenda 21 and local Agenda 21 will also be discussed in this essay, because it's an instrument for local governments to specify their work towards sustainable development. I have interviewed civil servants in leading positions in the municipalities? work with environmental questions and sustainable development. In the choice of method for this thesis, I use the qualitative method and for the interviews I chose the ?semi structure way of interviewing?.This thesis shows that local governments? implementation of sustainable development and Agenda 21 differ between the municipalities.

Prescribed burning was commonly used for site preparation in Sweden to establish new forests until the 1960?s, when mechanical scarification was introduced. During recent decades the interest in prescribed burnings has increased again, mainly due to certifications of forestry stating that 5% of the regeneration areas should be burned on dry and mesic soils. The objective of the study was to evaluate actual influence of prescribed burning compared to other site preparation on stand stem density, growth parameters and tree damages for Scots pine (Pinus sylvestris L.) after direct seeding and planting. The study also attempts to simulate growth until first thinning.

AbstractThe rise of globalization has made ??the sustainability aspect emerged as a sign that peoples? actions must change. Tourism is now one of the fastest growing industries in the world that has an impact on people, nature and cultures. The purpose of this study is to gain a better understanding how different tourism actors use and express the concept of sustainable tourism development in the co-operation organization Kiruna Lapland. One of the most visited places in the north of Sweden.
