It is essential to reuse- and recycles residues to decrease the amount of deposit materials and reach sustainable energy use. Two ways to work towards this is to recycle wood ashes to the forest as nutrient compensation and extract biogas from combustion of biomass.The aim with this study was to decide whether wood ashes that been used for biogas upgrading with accelerated carbonation also can be used as a nutrient compensation in the woods according to recommendations from the Swedish Forest Agency (Skogsstyrelsen).The ashes that were used in this study came from Johan Andersson who works at JTI in Uppsala, who also treated the ashes with biogas. The ashes have, in both untreated and treated condition, been analyzed in this study according to contents of elements, leaching properties, hardening properties and contents of crystalline phases, to evaluate what impact carbonation with biogas has on the ashes.The accelerated carbonation led to hardening of the ash, and decreased amount of CaO- and increased amount of CaCO3. The CO2-uptake also entails a dilution of the elements, and the content of nutrients and trace elements decreases. However the results show an indication of an uptake of S from the biogas to the ash, since the dilution had a smaller impact on S than the rest of the elements.

The Angola black-and-white colobus (Colobus angolensis palliatus) is a subspecies of Colobus angolensis inhabiting fragmented forests in coastal Kenya and Tanzania. C. angolensis is regarded as Least Concern in the red list of IUCN because its populations are abundant. However, the populations of C. a.

User participation in the planning process of renewing the yards of existing residential areas was introduced in Sweden in the 1970s. It arose as a solution to many of the problems which became common in the residential areas built within the Swedish million program. The aim with the million program was to build one million homes within ten years. The same year as the million program was completed, in 1975, government subsidies to improve the residential yards were introduced. One of the conditions to get the subsidies was that the residents had to be involved in the planning process.

Is there such a thing as unadulterated nature? All that surrounds us is culturally modified by man somewhere along our past. But culture is only a fictitious conception itself, created in an attempt to break the world into controllable objects.So in what do we find culture? In everything? In the objects or the stories they embrace? Who chooses what?s worth saving and how to save? Choosing what is culture is made from personal, ingrained dichotomies of what?s important and what is not. A selective eye creates a distorted truth, which could have unintentional long-term effects.This thesis will give a historical account of the archaeological discipline?s development in tending to our cultural heritage.

This paper aims to explore the phenomenon urban wind energy, its visual effect on built environment and the factors that affect the opinion towards new elements in the city. A place study of the city Gävle serves as a complement to the theoretical part of the paper. The theoretical discussion opens with an account for the technical and economical conditions of urban wind energy. It presents the technical basics, different types of turbines and a discussion occurring wind related techniques in built environment. Today, the knowledge of how the wind moves and acts in the rural landscape is quite good.

Improved wireless datacommunication with the forest machines might be the next big step in the logging process. The use for wireless communicationsystems within the forestry is among other things to report the production from the forest machines, to supply the machine opera-tors with the right information and for safety. CDMA2000/ 450 is a third generation mobilecommunicationsystem which could replace the old NMT- 450 and for comparatively low costs. The reason for the low costs is that you only have to use the old NMT- 450 masts and supply them with new equipment. In the test of CDMA2000/450, that has taken place in northern Uppland, two kind of files have been sent.

When visiting Scaniaparken in Malmö you have the possibility of listening to music streaming out of grass-covered hills. In Helsingborg children can compose their own music and play for their friends on the playground. On a square in Nacka Strand you can hear birds singing in the quiet intervals of traf?c. What the places have in common are that they all contain sound installations.

In Northen Bungoma, Western province ? Kenya, the Vi-Agroforestry Project (VI-AFP) has introduced a new project that covers 7000 households. To succeed with the project, a water resources protection project, agroforestry methods will be implemented to secure the water quality of the area. In this thesis a foundation is laid for future follow-up studies of land cover and land use of this area. To carry out this study an existing method from a cooperation between VIAFP and Dalarnas University (HDa) has been implemented.

This report is a B.Sc. Forestry thesis work at the school for Forest Management, SLU. The work was an assignment from the forest owners? association Mellanskog. The aim of the work where to investigate the economical result of removing undergrowth trees before first thinning, and a follow-up of the contractors and their compliance with Mellanskog standards. This thesis work was divided in three parts: The first was to find a relation between the net volume from the first thinning and the cost of cleaning undergrowth trees. Secondly there was a follow-up in the field, to investigate whether the contractors have done the undergrowth cleaning according to Mellanskog?s directives.

The research of today shows that natural environments are importantfor children's physical and mental development. It alsoshows that children often opt out of the traditional equipmentplaygrounds have to offer. By breaking the boundary betweenthe playground and park, is it possible to create a new spacethat will encourage rather than demand play? Through gatheringinformation and talking to landscape architects, designers,and children, I realized that today's parks already have environmentsand objects that could be used for playing. But whatthey need is something that makes the environment even moreinviting for children to play.

Title: Experiences of physical activity in a flat country Regular physical activity provides many chronic diseases and is an important contributor to health promotion. According to Swedish goals for public health, community planning ought to provide opportunities for exercise in all groups of the population and exercise in daily life should be uncomplicated, even in rural areas. The purpose of this study was to explore how individuals living in a flat country experienced their opportunities for exercise on a regular basis. Four semi-structured interviews were carried out with a phenomenological approach and for the analysis a phenomenological-hermeneutic method was used, resulting in two main themes and nine sub themes. The first main theme ?The reciprocal relation between physical activity and the landscape? showed that the informants experienced that they had good opportunities in the landscape for physical activity, it was easy to exercise on a regular basis, provided there was motivation.

Many wood living insects are considered threatened by modern forestry due to the reduction in amount of dead wood. During the last decade various methods have been used to enhance the quantity of dead wood in managed forests. However little is known how and if these methods are aiding saproxylic insects. The threatened tenebrionid beetle, Upis ceramboides, is already extinct in southern Sweden. It develops in white rotted dead birch (Betula spp) and requires sun-exposed sites.

Outdoor education is a teaching method which has several advantages to traditional classroom tuition. Its ideas have a long tradition and find support in the current Swedish curriculum. The place for the tuition is a central aspect within outdoor education. This essay aims to investigate what good places for outdoor education look like as well as discussing how the characteristics of such places can be used when designing schoolyards. Previous research shows that nature has characteristics that suit outdoor education well.

During the spring semester of 2009 I have participated in what was to become the project The Allotment Plot; a collaboration between the Swedish University of Agriculture and the Wanås Foundation. As one of six students in landscape architecture I have experienced a group based learning process with the point of departure in the designing of an organic and experimental kitchen garden at Wanås, a sculpture park for contemporary art. The project came out as neither us nor any other of the people engaged could have guessed. What was meant to be a garden turned out to become an entire cultivation movement. As students, we have gained a lot of experience through praxis; experience that will be valuable for our future profession. The project has also opened up the possibility to question and reflect upon what our profession and education could or should be about. This thesis focuses on the role of communication and the production of communicative tools in design processes and landscape architectural practice. It discusses how communication may be used in an exploratory and ?un-securing? way, and how this may dislocate the professional role, especially in situations where the design action, as in the case of this study, demands a high degree of transdisciplinarity and collaboration. .

The use of chainsaws in both private forestry and commercial companies is highly associated with personal injuries and accidents with deadly outcome. As a result to this, a driver?s license for chainsaws was presented in the year 2005. To get the license you have to attend a course given by the Swedish Forest Agency or one of several private educators. This study is an evaluation of one course given by the Swedish Forest Agency in Uppsala.
