The purpose of this essay is to analyze and show possibilities how a city can grow into the scenery of a oak dominated landscape and how this encounter can add values to the city. The city in focus is Linköping, a city that is approaching one of Sweden?s largest oak dominated cultural landscapes. To this landscape high ecological and cultural values are connected. The recreational values are also of importance especially because of its urban location also because the city is mainly surrounded by flat agricultural land.

The visions of the United Nations concerning sustainable development and conservation of biodiversity can only be realized if the human population succeeds in creating coexistence between human and wildlife. Landscape architects are able to influence on how landscapes are to be maintained and developed. The negative impact of infrastructure on wildlife has become a critical problem in Sweden and other parts of Europe. Wildlife crossings has been developed as a solution for the problems of road barriers in the landscape. The crossings are made to give animals a better opportunity to cross roads.

A diet based on a bigger part of locally produced vegetables can contribute to decreasing environmental impact and improved health. In Gotland horticulture has increased more than in Sweden in total during the last 15 years. To investigate possibilities for development of Gotland´s horticulture, the cultivation of potato, vegetables, fruits and berries was mapped through a questionnaire among growers. Interviews and a workshop with growers and reseller were conducted to investigate the interest and prerequisites for growing new crops. In total approximately 2340 hectares of potato, vegetables, fruits and berries were grown in Gotland in 2012.

De senaste årtiondena har det blivit allt viktigare att korrelera och jämföra resultat från olika klimatarkiv, till exempel iskärnor, sediment, trädringar och speleothem, då det är av stor vikt att kunna sammanställa resultat från olika studier på en gemensam tidsskala med relativt högupplösning. Ett av de viktigaste verktygen för att det ska vara möjligt att göra exakta jämförelser av klimatarkiv från kvartärperioden kan vara tefrokronologi. Idag har fler än 125 tefrahorisonter med isländskt ursprung identifierats i den nordatlantiska regionen, men många av dessa har dock ännu inte identifierats utanför Island. I Sverige har det främst gjorts undersökningar i de västra och mellersta delarna av landet, men det har även gjorts ett par undersökningar i andra delar av landet också, så som norra och södra Sverige. Syftet med studien var att bestämma koncentrationer av tefra i Karinmossen, Gästrikland, som ligger i ett område där det inte har gjorts några tidigare studier av förekomst av tefra.

Today's Swedish large-scale forestry uses almost exclusively computer-aided bucking. It allows the harvester computer, using an optimisation price list (steering price list), to maximize the value of each tree. The optimisation price list can be adjusted so that the industry gets the raw material it demands from the forest. There are various simulation programs that can be used when constructing a optimisation price list. The simulation program merchandise a database of stem shapes using a given price list and mimics a harvester's work. To get the demanded raw material for the industry it is important to use a well-adjusted optimisation price list.

Wind power is an energy source that is becoming increasingly popular in Sweden and around the world. The establishment of large wind farms supply and contributes to energy production within grid in search of a more sustainable energy production. Wind power is becoming more popular and opens up new areas of implementation. More cities are starting to use small-scale urban wind power, everything from full-scale work for a little less work adapted to the villas. Sweden has high goals regarding the production of green electricity and the work which deals with the conditions Sweden plays in achieving those goals.

Ljusförorening är ett relativt modernt fenomen som allt mer påverkar tillgången till en stjärnklar natthimmel. Det finns en mängd olika internationella organisationer som arbetar för att minska ljusföroreningar och för att bevara natthimlens synlighet, bland andra International Dark-Sky Association, Royal Astronomical Society of Canada och Starlight Initiative. I den här uppsatsen undersöker jag ett antal strategiska dokument genom textanalys, för att analysera deras huvudsakliga motiv till förändringar och för att få en överblick över vilka sorters åtgärder som dessa organisationer föreslår. De analyserade dokumenten är Astrolabs Practical Guide for Lighting, Dark Sky Societys Guidelines for Good Exterior Lighting Plans, International Dark-Sky Associations Practical Guide, Royal Astronomical Society of Canadas Dark Sky Guidelines, Patersons Sark ? Dark Sky Island Lighting Management Plan, Flagstaff Dark Skies Coalitions Lighting Tips, Starlight Initiatives Defence of the Night Sky and the Right to Starlight och Narisda och Schreuders Light Pollution Handbook.

Montagu´s harrier (Circus pygargus) is a diurnal, Eurasian raptor, which migrates from its northern breeding grounds to winter in sub-Saharan Africa. In Sweden, its core breeding area is centred on the island of Öland, with a stable breeding population of approximately 40 pairs. The province of Uppland is on the northern end the distribution range, where 4-8 pairs have regularly bred since the 1980s. In Sweden, the Montagu?s harrier is classified as an endangered (EN) species. This classification is partly due to a lack of preferred nesting habitat, such as shrub-lands or dense wetlands with Claudium spp.

Storm water management has become a more important matter as urban areas are expanding and natural areas are being exploited. As nature landscapes are being converted into hard surface areas storm water flow is affected both in terms of velocity and size. A flow increase can easily result in a flooding if the dimensions of the pipeline system are inadequate. Considering predicted upcoming climate changes, flooding?s may become more common in urban areas in the future.

From the pre-Roman and Roman Iron Age, a number of different fossil agrarian landscapes can be found in southern Sweden - clearance cairn areas, celtic fields, stone-wall complexes and geometrically laid-out strip fields. With two different comparative analyses, this paper tries to explain some of the differences between clearance cairn systems and the other fossil field systemsThe shape of the early Iron Age agrarian landscape varies between different provinces of southern Sweden. At Gotland, celtic field systems were laid-out before 500 BC. In Småland at the same time, areas with clearance cairns were created. How can the difference be explained? The different physical appearance of clearance cairn areas and celtic fields can be explained by the different ways to handle the ard in till and in sandy soil.

The Swedish forest have about 100 000 km of watercourses and it?s an important structure in Swedish landscapes and catchments. In some of the watercourses lives spieces like the freshwater pearl mussel (Margaritifera margaritifera) and brown trout (Salmo trutta) which both are sensitive for inteference from the forestry. The new EU water framework directive has a goal that all surface water will have high or good ecological- and good chemical status at latest by the 22nd December of 2015. The study has been made in the catchment of Håltjärnsbäcken and it is from a national perspective one of the most valuable streams in Sweden and which also have been included in a LIFE-project. The catchment is situated within the Eco-park of Malingsbo-Kloten and managed by Sveaskog AB.

Skärgårdsstiftelsen, which is responsible for several of the archipelago islands in Stockholm, has chosen to explore the possibilities for more sustainable heating systems in buildings on the islands in collaboration with KTH. A reduction of energy use and improving the efficiency of existing heating systems are included as part of the environmental work. This report studies the island of Grinda, which is located outside the area of Vaxholm in Stockholm. The study area consists of a guesthouse consisting of a restaurant as well as conference facilities and four neighboring cottages used for overnighting. The cottages now run solely on direct electricity, both for heating and hot water.

Kulturhistoriska platser har allt mer börjat benämnas som kulturmiljöer, vilket är hela områden som har påverkats av människan på ett eller annat sätt. I dessa områden fanns andra värderingar än endast det kulturhistoriska, oftast formulerade som hållbarhet och utveckling. Båda dessa begrepp är grundpelare i uppsatsens teoretiska utgångspunkt, resiliensteorin. Resiliensteorin är en förgrening till systemteori, i vilken samhället ses som en helhet. Enligt resiliensteorin är samhället likt ett socio-ekologiskt system uppbyggt av flera variabler i samhället, dessa variabler är; sociala, politiska, miljömässiga och ekonomiska.

It has been observed by both onion producers and a plant protection advisor on Öland (an island off the east coast of Sweden) that basal rot is the largest contributory factor to reduced onion quality and yield. Basal rot is mainly caused by species of Fusarium fungi. The aim of this study was to: a) investigate which species of Fusarium that can be found in onion produced on Öland, b) describe the symptoms caused by the different Fusarium fungi found and c) explore, through interviews with the onion producers on Öland, the mechanisms that may be involved in the observed increase in basal rot.Onion bulbs (Allium cepa) were sampled on two occasions. In total 181 onions from 11 different fields were analysed. In addition, eight onion producers were interviewed.

Salmonellainfektioner orsakar en betydande sjuklighet och innebär en stor kostnad för länder inom EU. Inom fjäderfäproduktionen har serovaren S. Enteritidis störst betydelse. EU-kommissionens "Zoonosis Directive" från 2003 innehåller regelverk för kontroll av zoonoser inom EU. Arten Salmonella spp.
