Naturhänsyn på slutavverkade hyggen i Östergötlands län.
95% of the productive forest land in Sweden are now being exploited for forestry. The new Forestry Act of 1993 equate the goal of production and the environmental goal which means that the objective for forestry is a sustainable yield, while the biological diversity must be preserved. Recent years results from the inventories of the Board of Forestry show declining trends in how nature conservation aspects taken into consideration at the felling sites.The aim of this study is to investigate what happends with the nature consideration taken at felling sites in the long run. 20 final fellings in the county of Östergötland were re-inventoried 7-9 years after final felling. These felling sites had previously been inventoried before final felling (P0) and one year after final felling (P1) in the inventory Polytax by the Board of Forestry.
Kombinerad bekämpning i strid i bebyggelse
Even though battles have been fought in built-up areas for a long time, there have not been any specific theories connected to it. As the world becomes increasingly urbanized, the problem of not having any complete theories with which to analyze military operations in urban terrain becomes bigger. This essay aims to contribute to the field of military theory by investigating if Robert Leonhard?s theory of combined arms can be used in analyzing such operations and to be able to explaining the outcome of them. The main question posed in this essay is; to what extent can Leonhard?s theory explain the outcome of military operations in urban terrain? The method used to answer this question is a comparative method formed as a case study of two military operations in urban terrain, Operation Vigilant Resolve and Operation Phantom Fury, which both took place in Fallujah during the Iraq war 2004. The intention is to test Leonhard?s theory in both cases by assigning the theory several indicators, which are tested in each case. The result shows that the indicators appeared almost equally in both cases, even though one of the operations was said to be a success and the other a failure.
Anva?ndarbehov i samha?llsplanering : en fallstudie av anva?ndarcentrerade metoder
Public participation in urban planning is meant to increase democracy in the planning process. Even though all citizens have the option to participate in urban planning debates, few seize their chance to partake. This thesis describes a study on how user needs are met and prioritized in design processes concerning urban planning. The aim was to determine whether user-centered design (UCD) methods could be used as an avenue for public participation in urban planning and ultimately invite more citizens into the planning process.The thesis details a design process where a team worked to develop Farsta, a suburb of Stockholm. The design problem was the question of how Farsta could become an attractive business location.
Identitet, skog, fjäll och ren i Härjedalen : ur ett samiskt perspektiv
This paper examines how nature is understood in the province of Ha?rjedalen by the sami population of the area, through interviews with three informers and photographs taken by the author. Pictures and answers point in the direction that much of nature is understood through the reindeer, the most important key symbol of the reindeer herding part of the sami people and their kin..
Metoder för kulturmiljöanalys
Questions concerning the Cultural Heritage must be integrated in social planning.Therefore there is a need for adequate methods for cultural environmental analysis, toreceive knowledge that is relevant in an integrated conservation. The thesis is a review ofmethods for cultural environmental analysis and discusses the qualifications necessary fora method in order to receive adequate information as well as it discusses what kind ofinformation to be considered relevant. The thesis also analyzes a specific method forcultural environmental analysis in order to exam if it has got the qualifications concludedas necessary if it is to be used in an integrated conservation. The conclusion is that amethod for cultural environmental analysis should collect information about the entireenvironment (integrated information about nature and culture, in a historical perspectiveand how it is today), about social structures, physical remains (buildings etc) and what thecollected information tell about the history of the studied area, as well as what is importantin the landscape of today. Information about how the environment should be treated in thefuture is also of importance.
Ekosystemstödjande och multifunktionella växtval i urban miljö : En fallstudie med utgångspunkt i Nacka stadsbildning
This study has investigated how urban vegetation can be used in a multifunctional way to support ecosystem services in urban environments. Nacka municipality is in the start-up phase of building what is to become Nacka city. This provides a unique possibility to study and analyse what role the vegetation play in making the city a healthy living environment and how it needs to be adapted in order to be resilient against changing climate conditions and how the effects of those changes can be regulated. The study further investigates how airborne pollution, caused by urbanization processes, can be regulated or reduced by vegetation or species selection. Methods used in this study were a combination of qualitative interviews and literature studies, seeking to answer the questions: Which specific ecosystem functions are needed in the urban environment and which aspects will influence the ecosystems ability to deliver the functions in demand? And which plant species have the right mechanisms needed to deliver those functions? These questions have been studied and analysed in a local based context where the local conditions ands site specific needs of Nacka define criteria for plant selection.
The artistic planner and the planning artist in participatory practices in urban development
A brush of paint on a grey compound wall can mean so much more than simply an addition of colour. It can meanan appropriation of public space, a shared public space enclosed by a wall now ?owned? by someone. It can meanan arisen conflict leading to debate about the right to use public space.The Wall Project is a Mumbai based beautification project that uses paint and outdoor walls to brighten uptheir city. The Urban Typhoon workshop is an activity set up in self-evolving neighbourhoods where municipalinterference is scarce.
Strategier mot urban sprawl i svenska städer : En fallstudie av åtta svenska kommuners arbete
Urban sprawl är ett problem i hela världen. Ekonomi, hälsa, miljö och jordbruksmark är några saker som stadsutbredningen har effekter på (Habibi, 2011). I USA började problemen med urban sprawl efter andra världskriget när möjligheter till billiga bolån skapades. Detta gjorde att fler människor hade möjlighet att flytta till enfamiljshus i förorterna och användandet av bil som transportmedel ökade (Duany, 2010). Stadsutbredningen i Sverige startade efter andra världskriget då bilismen ökade även här.

Stora Södergatan : communicating a street´s potential through site reading
In urban planning and design today interventions tend to take place in already existing areas and inevitably effect also surrounding areas. The many parties involved in any change leads to a demand for a shared language around these areas. This thesis aim to, through understanding and communicating a site, Stora Södergatan in Lund Sweden, inspire to a novel way of looking at an urban site preceding design- or planning interventions. Based on a theoretical framework where site is considered as a relational construct, material as well as immaterial, a framework for site thinking is constructed. Further, with theory of representation, the communication of the site is emphasized and accounted for as part of the framework.
Från ett nödvändigt ont, till en naturtyp värd att bevara - en studie av ljungheden i Sandsjöbacka och Grönabur/From a necessary evil to a nature type worth protect - a studie of the Calluna heath of Sandsjöbacka & Grönabur
In the middle of the 19th century was Calluna heath the major nature type in Halland, but the remaining parts today is only 1 500 hectares which is a 99 % decrease of the Calluna heath mainly due to an increase in forest plantations and arable fields. I have made a quantitative study how the Calluna heath of Grönabur & Sandsjöbacka has changed between 1841 and 2005 and why it didn?t disappear in the same manner, as it did in other parts of Halland. The studying of original sources as historical maps, literature and by doing field visits has been significant for the final result. The main reason for the different development of the Calluna heath in the investigation area (69 % decrease), compare to elsewhere in Halland, is the establishment and management of a nature reserve..
Prevalence of antibodies for Peste des petits des ruminants virus and Brucella and related risk factors in goat herds in urban and peri-urban agriculture in Kampala, Uganda
The world?s population reached more than 6.9 billion people in July 2011. It is expected that the population growth during the next 40 years will take place mostly in low-income countries and the population increase will be 2.3 billion people during 2011-2050. A rapid urbanization is also expected to result in 57.7 per cent of Africa?s population living in urban areas in 2050.
Urban green in Vientiane, Lao PDR : a minor field study
This is a Minor field study addressing the current situation
in Vientiane, Laos where focus lies on the green structures
past, present and future.
The city of Vientiane is growing rapidly and as a result of
this there is a increasing development. The once peaceful
capital known for it?s lush and green environment is
standing in a crossroad where important decision must
be made to preserve valuable areas. During 8 weeks inventories and observations where made resulting into a
proposal for future development. The proposal is divided
into three parts.
The urban fringe and surrounding landscape are still
quite undeveloped and have a great potential of green
wedges etc.

parks and squares..
Bildandet av naturreservat : uppföljning och klimatanpassning
AbstractWe are facing a century of rapid change in climate, with significant challenges in managing the impact of changes in living conditions for plants and animals. We can already see the responses of species through changes in phenology and spatial distribution, which may change ecosystem structure and function, with subsequent effect on ecosystem services and biological diversity. In Sweden, between 2005 and 2010, the red-listed species has increased by 13 % and similar trends can be seen across the world, making it difficult to attain national and international environmental objectives of preserving biodiversity. One way to reduce the loss of biodiversity is to protect nature from exploitation by allocating valuable areas as nature reserves, but climate change affects protected areas just as much as other landscapes and therefore requires elaborate systems of protection to facilitate species' survival. The paper has examined how the decisions and management plans for nature reserves in Sweden have been followed-up and whether they are climate adapted or not by examining 30 nature reserves, classified as newly formed (2012), recently revised (2009-2011) and older (1977-2007) reserves, and assessed what is in the decisions and management plans for follow-up, revision, long-term goals and documentation.
Framtidens stadsträd för en fungerande grönstruktur
The effect of climate change places demands on how we build cities. Cities have to be built denser to meet the objectives of sustainability but as a result of this densification city green areas are at risk of exploitationand disappearing. The question this raises is whether there has to be an opposition between a dense and a green city?Urban trees are playing a very important role in cities. They stand as the major part of the vegetation in citieswhich are otherwise dominated with concrete and stone.
