NÀsbyholm - parken och de nÀrmaste omgivningarna ur ett historiskt och nutida perspektiv

The goal of this work has been to search historical materials, to identify the park's historical development, to prepare proposals on measures and that work should be the basis for further research. The aim has been to train us in searching for and use of materials and to gain an understanding of the process of work with older plants. In the process we have sought and found materials in archives, through literary and oral sources, and email contacts. Because of its excellent location perched on an islet in the low landscape NĂ€sbyholm was long a fortress. The old castle on NĂ€sbyholm was from the late 1400s but the site was fortified much earlier. The islet was at this time completely surrounded by water and there was a drawbridge over the narrow waterline. The owners are liable since the late 1200s.

?Paid pollination? ? en tjÀnst för odlade grödor och biodiversitet : Analys av den kommersiella pollineringens utbredning och utveckling i Taranaki-regionen, Nya Zeeland

Pollinering Àr avgörande för ett antal kommersiella grödor samt för olika vÀxtarter i inhemsk vegetation. Honungsbi (Apis mellifera) Àr en av de viktigaste pollinerarna. I regionen Taranaki i Nya Zeeland finns tvÄ aspekter av kommersiell pollinering, dels betalar mÄnga biodlare för tillgÄng till manuka för de antibakteriella egenskaperna honungen fÄr av den, dels betalar frukt- och grönsaksodlare för pollinering av sina grödor. MarkÀgare kan ha ett intresse av att spara manuka pÄ sina marker och fÄ en utkomst frÄn biodlarna genom att dessa betalar för Ätkomsten. Studien syftar till att klarlÀgga de effekter som kommersiell pollinering har i Taranaki-regionen idag och för framtida anvÀndning och har utgÄtt frÄn intervjuer med biodlare, frukt- och grönsaksodlare och personer som representerar myndigheterna.

Barnens trÀdgÄrd : Barnsjukhusets utemiljö - Uppsala

The outdoor environment at Children's hospital, the University Hospital, Uppsala, is used by sick children at the Children's hospital, their families and the hospital staff. The staff at the Children's hospital wanted to render the site more attractive and available. This graduation thesis is a proposal about how the outdoor environment at the Children's hospital can be improved. The aim is to design an environment for the sick children, their families and the hospital staff that will serve as a place for relaxation and privacy, as well as for play and movement. In order to find support for the redesign of this site I read literature about theories concerning healing environments, healing gardens, children's play and designs for children.

Att förnimma det vilda

Att förnimma det vilda utforskar det vilda som fenomen, hur det konstitueras, upplevs och uttrycks i ett urbant sammanhang. Syftet med uppsatsen Àr att undersöka landskapsarkitekturens möjligheter att skapa goda - vilda - livsrum dÀr det vilda lÄter sig förnimmas. Arbetet belyser Àmnet utifrÄn ett vÀsterlÀndskt perspektiv och befinner sig i grÀnslandet mellan landskapsarkitektur, historia och miljöpsykologi. Arbetet gör ett besök i historiska skildringar av det vilda, i miljöpsykologins preferensstudier pÄ vilda miljöer och tar slutligen en titt pÄ hur det vilda i ett nutidsperspektiv tar sig uttryck i kulturellt formsprÄk. Arbetet tar avstamp i historien och skildrar hur mÀnniskor betraktat vildmarken frÄn 1300-talet fram till slutet av 1900- talet. Det framkommer att det vilda har starka religiösa kopplingar och att det betraktats som en motpol till civilisationen.

NaturhÀnsynen 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.

Hantering och mellanlagring av jordmassor

This report deals with handling and interim storage of soils which are planned tobe reused in construction works. The types of soils that are dealt with are gravel, topsoil and sand. The thesis work has been carried out in collaboration with Skanska Sverige VÀg och AnlÀggning Sydost. The main goal is to find an area for using to store soil in between projects.Studies of laws and regulations regarding exploitation and storage of soil has led to a theoretical background upon which the report is based. Background informationhas also been gathered in meetings with the employees at Tekniska Kontoret and LÀnsstyrelsen in Jönköping.On the basis of literature studies results, a general template has been developed for which desirable properties a possible location should meet.The model was applied to find a number of possible options in the vicinity of Jönköping.

Rehabilitering i staden : att planera för dem som inte tar nÄgon plats

Dagens stÀder blir allt tÀtare i takt med att befolkningen ökar. Samtidigt avbefolkas vÄr landsbygd. Samtidigt avlÀgsnar sig staden mer och mer frÄn omgivande natur och lantbruk. Samtidigt mÄr vÄr befolkning sÀmre och sÀmre. Sjukdomar som utmattning, stress och depression ökar.

TrÀd som temperaturreglerare i stadsmiljö : en litteraturstudie gÀllande trÀdval för urbana miljöer

VÀrmeböljorna blir allt vanligare i Sverige vilket kommer kosta sjukvÄrden miljardbelopp. Hur kan denna trend motverkas? TrÀd kanske inte Àr hela lösningen pÄ problemet, men Àr en hjÀlp pÄ vÀgen. Det urbana landskapet har idag högre temperatur Àn omgivande landsbygd. Detta fenomen, den sÄ kallade urbana vÀrmeö-effekten, beror bland annat pÄ att hÄrdgjorda ytor absorberar solenergi, antropogena kÀllor utsöndrar vÀrme, luftföroreningar fungerar som vÀxthusgaser och bristen av nerkylande vegetation. Dessa faktorer bidrar till en ohÄllbar temperaturstigning. Kandidatarbetets mÄl har varit att ta reda pÄ hur trÀd bidrar till en temperatursÀnkning inne i stÀderna och att identifiera urvalskriterier för att vÀlja trÀd ur temperatursynpunkt som samtidigt fungerar i urbana miljöer.

Klassning av fjÀllbjörkskog enligt FAO:s definition av skogsmark med hjÀlp av flygburen laserskanning

Sweden?s forestry legislation was updated in 2010 and a new definition of forest land was introduced. This definition was adapted to the one used by the Food and Agriculture Organization of the United Nations (FAO) for international statistics on the state of the world's forests. It is in short based on the lands ability to grow forest that reaches 5 meters, 10 % canopy closure and has a continuous distribution, according to FAO at least 0.5 hectares. A country-wide laser scanning is now carried out for the production of a new national elevation model; the laser data also provides information on forest height and density.

Framtidens kongresshus : Stadsbyggnadsvisionen i Jönköping

Since a couple of decades the community of Jönköping has worked out an urban vision of how the city should be appropriated expanded. The prospect extends to around year 2040 and deals with the area south of lake Munksjön in Jönköping, Sweden. Today there is a proposal of how this would look like and what main public functions that should be located there. One issue in the so-called urban vision 2.0 indicates a congressional building. This report describes how such an object can be designed according to the urban vision conditions.The work is focused on three main themes;* Architectural concept and a modern form of expression.* A functional attractive congress building in a new planned town centre.* General concept of a realistic structure system that meet the spatial and architectural possibilities.Various concepts in the meeting industry and in the architecture field are identified in order to understand the concepts and ideas with todayŽs congress buildings.

Undersökning av sjÀlvspridning av contortatallen i norra Sverige

Over the past 40 years 600 000 ha of lodgepole pine (Pinus contorta ssp. latifolia (Engelm.) Critchf.) has been planted in Sweden (280 000 ha on SCA's forest land alone which represents about 15% of the company's total forest land area). In the early 70's SCA situated a number of experimental stands in order to investigate different aspects of the exotic tree, primarily growth rate. To be able to compare the two species plots with scots pine (Pinus sylvestris L.), this species was also planted at the same time and under the same conditions. A number of questions should always be raised when exotic species are introduced in an ecosystem. Invasiveness, the pathogen situation and purely ethical issues should be discussed.

Biochar as soil amendment in flow-through planters - for increased treatment of zinc roof runoff

In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.

VILKEN STRANDVEGETATION BIDRAR TILL DET ORGANISKA MATERIALET I KUSTN?RA SEDIMENT? Kols?nkor/k?llor, nedbrytbarhet och eDNA sp?rning

Coastal sediments are important carbon sinks, storing organic matter and thereby helping to reduce the amount of greenhouse gases in the atmosphere. However, they can also act as carbon sources if the deposited organic matter decomposes rapidly, contributing to increased greenhouse gas emissions and global warming. Rapid decomposition partly depends on the degradability of the material itself. In this literature review, I examine which coastal plant species dominate different locations along the Swedish coast, based on coverage data from the ClimScape project (www.climscape.se). For the most dominant species, I investigated the type of organic matter they may contribute to the sediments and based on those results I qualitatively assessed which sites that may function as carbon sinks or sources.

Stadsdelsförnyelse i Norra BjörksÀtra, Sandviken

The housing estates in the outskirts of Sandviken, consist of relatively large scale apartment buildings. This report, that is a B.A. thesis at 10 Swedish university points, aims to investigate and describe the opportunities to improve safety and security for inhabitants in Norra BjörksÀtra. The purpose with this report is to make Norra BjörksÀtra to a more attractive place to live in, by changing the negative trends in the area. Since demolition of at least some of the houses could be of current interest in some years; the purpose is also to investigate whether demolition or renewal of the area is the best solution.

Gaturum för möten - hur gaturummets skala och gestaltning pÄverkar stadens sociala hÄllbarhet

MÄlet med denna uppsats har varit att undersöka och diskutera hur gaturummets skala och gestaltning relaterar till möjligheten för möten mellan mÀnniskor. Uppsatsen har ocksÄ undersökt huruvida Àven vidstrÀckta gaturum kan fungera för mÀnniskor att vistas i, samt om det finns insatser som kan förbÀttra dessa gaturum. Uppsatsen syftar till att förstÄ hur Jan Gehl och Jane Jacobs erfarenheter kan tillÀmpas pÄ konkreta platser i urban miljö, för att skapa ett analysverktyg att förstÄ stadslandskapet med. Begreppet ?mÀnsklig skala? anvÀnds i hög utstrÀckning bland landskapsarkitekter, men det Àr osÀkert om dÀr finns en konsensus kring begreppets innebörd? Uppsatsens första del bestÄr dÀrför av en utredande text kring vad detta begrepp kan innebÀra. Med hjÀlp av en litteraturstudie samt dÀrpÄ följande observationer av tvÄ gaturum undersöktes huruvida det gÄr att se kopplingar mellan teori och verkliga fall. Gaturummen observerades med avsikt att studera om, hur, och i sÄ fall var sociala interaktioner förekom mellan mÀnniskor.
