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.
Locally valued habitats, species and sites and their significance for collaborative land use planning around Manusela National Park, Central Seram Island, Moluccas, Indonesia
When new land use policies are made, opinions of stakeholders need to be taken in account, to avoid future conflicts. The motivations of commercial enterprises are often clear and easily communicated but due to inaccessibility and language barriers the indigenous people?s perspectives and needs are harder to reveal. This study therefore aims to identify species and sites of importance for the local people in Masihulan village on Seram Island, East Indonesia. This is a first step to facilitate better integration of local people´s needs into local government decision-making processes.Researchers at the Center of International Forestry Research (CIFOR), with headquarter in Indonesia, have developed an approached called ?Multidisciplinary Landscape Assessment? that aims to assess important natural resources for local communities in tropical countries.
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.
Analys av linjetaxering i samband med gallringsinventering med avseende på kvalitet, tillförlitlighet och framtida utformning
Modern forest owners are very familiar with forest management and forest economics. Therefore they have high demands for quality in forest operations. Guarantee of quality in the shape of self-checking activities is an important tool to guarantee a well managed forestry operation. To meet the forest owners? demands on guarantee of quality and the entrepreneurs wish of an easy method for self-checking, the forest owners association, Södra skogsägarna, has developed a new method for thinning inventory.
The purpose of this study is to evaluate the method that is used for self-checking and to find ways to develop and improve of the method.
The data has been collected by inventory in a number of stands with circle-area survey and with strip survey, which is method that is used for self-checking.
The results show that the strip survey does not diverge more than ±10 % in measuring values of basal area, number of stems, roads share, thinning quotient, outtake of basal area and total volume compared to circle-area survey.
Skogsvård hos privata skogsägare : vilka åtgärder utförs och av vem?
Many participants in the Swedish timber market procure raw material from private forest owners. They often also offer forest services to ensure reforestation after final felling. Selling silviculture services can be a part of creating a long term relationship with the landowner for future timber purchases. The Swedish Forest Agency monitors forest rejuvenation results in the entire country. In the latest survey (2006 - 2008) the proportion of approved regeneration area was 78%.
Prestation i traktplanering
This study was an assignment for the company Holmen which is located in the region of Örnsköldsvik, Sweden. The study was focusing on the responsibilities of a forestry planner during the planning season.
The study was investigating about how much time the planner spent in the office, in the car and out in the forest. Any other issues that would cause delays were also identified. To be more effective and to increase the number of objects to a district bank, a better preparation in the planning stage (for thinning?s or clear cuts) is needed as well as faster transition on to the next area.
Är objektiva moraliska värden möjliga utan Gud? : en teoriprövning av Moralens Landskap
What drove me to write this paper is the will to examine if there is a philosophically and scientifically viable alternative foundation for an objective morality other than what we like to refer to as "God". The American philosopher and neuroscientist Sam Harris presents in his book The Moral Landscape a thesis for an objective morality based on science in which he states that science can determine human values. The purpose of this paper is to perform a theoretical trial of The Moral Landscape, examining Harris' thesis and it's relations to the philosophical obstacles that stands in its way, these being mainly the famous philosophical principle "Hume's Law" and G.E. Moore's "Naturalistic Fallacy and Open Question Argument" and thus will serve as my main theoretical foundation. The results of my study was not conclusive since Harris in fact doesn't succeed in bridging the gap between facts and values on a scientific ground.
Hybridmodeller för prediktiv modellering skapade med genetisk programmering.
Det finns idag ett stort behov av att kunna klassificera stora mängder data på ett effektivt sätt. Prediktiv modellering är ett område inom data mining där prediktioner kan utföras baserat på tidigare erfarenheter. Dessa prediktioner presenteras sedan i en modell. Avvägningen mellan tolkningsbarhet och träffsäkerhet är ett begrepp som beskriver hur träffsäkra modeller ofta är ogenomskinliga, medan genomskinliga modeller ofta har lägre träffsäkerhet. Detta är ett problem eftersom det finns ett behov av modeller som är både träffsäkra och tolkningsbara.I denna studie visas hur man kan gå till väga för att skapa en modell som har en träffsäkerhet i klass med en ogenomskinlig modell, men samtidigt har en högre tolkningsbarhet.
Skissen och skissandet - landskapsarkitektens arbetsverktyg
What is sketching for a landscape architect? Does it involve anything else than the sketching process, the tool withwhich we work and carry a project through? The answer is yes, it is a process but one that includes many functionslike making notes in drawings or words for remembrance, a way to convey your ideas to others and to clearifyideas for yourself or together in a group. This thesis aim to give a broader picture of what sketches and sketchingis through many voices, and images made by architects, a psychiatrist, a teacher, and landscape architect students.The focus is on the hand made sketch and show many examples of what a sketch can look like.What is a sketch? A sketch can be many things, but the general consensus is that it is made fast and as a draft. Itcan be made in any material, two or three dimensional.
Epixylic, forest-interior bryophytes in young stands : importance of local environmental variables, propagule sources, and distance to bordering woodland key habitats
The reduction of coarse, dead wood is considered to be the biggest threat to flora and faunain boreal forests. Extensive harvest of logging residues would increase this reduction evenmore. However, the role of dead wood created at final felling for boreal, epixylic species isstill largely unclear. It is therefore of interest to examine whether epixylic species inhabit thedead wood in young, boreal stands, especially species considered to be confined to forests inlate successional stages.The aim of this study was to investigate whether forest-interior species in fact can inhabitearly-successional forests arisen after logging. The study was conducted in young standsbordering dead wood rich woodland key habitats.

The story of the forest - A folded textile wall for flexible rooms in public spacesIn the story of the forest the dragonfly is spinning yarn shiny as the sun. In the story of the forest almost everything can happen and almost everything is also happen there.Inspiration from Lennart HellsingThe goal in this exam work was to create a calm, playful space for children in public spaces. A place where children can hide and relax without being disrupted by the surrounding, a place where their imagination can grow and take place. The goal was also to make a flexible space for public spaces that could be used in different ways. Today many libraries want to be more than a library, they will work as a meeting place and you can find several activities to join in.
Strategic forest planning using AHP and TOPSIS in participatory environments : a case study conducted in Vilhelmina, Sweden
When a decision is to be made on what long term strategic forest management plan to use, consideration must often be taken to multiple objectives. Such decisions are very complex and a promising approach to handle them is by Multiple Criteria Decision Analyses (MCDA). The study is based on the problem that the MCDA that have been implemented into forest management planning have only had capacity to compare and evaluate a limited number of management plans; which means that there is a risk the most suitable plan is missed. The aim with this study was to test the applicability of combining the MCDA tools: the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and the Analytic Hierarchy Process (AHP) for including consideration to multi-objectives into strategic forest management planning. The study was based on the process of creating and selecting a management plan, using Heureka PlanWise, suitable for all the major objectives found in the forest holdings of a municipality in northern Sweden.
Våtmarker i urbana miljöer : växtgestaltning och planering
The practice of landscape architectural involves forming the space in our cities and suburbs, as well as the landscape surrounding. The need of exploiting green environment leads up to, among other issues, flood problem during heavy rain and overfed water environments. The problem is partially caused by the shortage of knowledge, how the environment is responding of the innovations made by the city- urban planning and how to get sustainability.
Research and knowledge how to take care of our environment, in a natural way, is increasing. The object of the thesis is to propose control and balance in urban wetlands, and discuss the difference a plant design can do.
The thesis deals with discourses in the field of landscape architecture, biological diversity, dam construction, limnology, planting design and management, pollution of the environment and urban design practice.
Orienterare, framtidens naturvårdare? : Inventering av markstörningar i samband med O-Ringen i Skåne 2014
As an increasingly rationalized forestry and agriculture have human interference in the form of tradition, grazing and use declined. There is a strong link between biodiversity and disturbance of the landscape. In sandy soils many insects and plants require exposed sand to survive while the disorder may contribute to seed dispersal in the woodlands. On behalf of O-Ringen Skåne 2014, a study of the interference from orienteering in sandy soil and the forest during competitions conducted. The aim is to clarify the interference of which orienteering runners contributes, through to inventory presence before and after the competitions in the bottom and field layer in three locations.
