WHITE HOUSE/GREEN HOUSE - En processpårande undersökning av klimatfrågan i USA
This thesis examines the process of securitization of the environmental issue in the United States. By using the theories of sectoral security and securitization by Barry Buzan and Ole Waever, commonly known as the Copenhagen school we go beyond the traditional security frames and examine where the environmental issue in the United States stand today within the securitization spectrum. The securitizing spectrum includes three levels in which an issue can be place: non-politicised, politicised and securitized.The problem, which we wish to address, is if there is a movement of the environmental issue in the United States towards becoming a securitized issue. In the light of these circumstances we also wish to explore who is behind the movement and also find out where the issue stand today. We do believe that Al Gore is a securitizing actor and examine his role in the movement of the environmental issueWe have come to the conclusion that there is an ongoing process of securitization in which the environmental issue have moved from being politicised to becoming securitized..
A Green Belt of synergies : a study on the implementation of a contemporary Green Belt
The prevailing urban migration is a worldwide process. This results in growing cities and a diminishing proportion of people living in the countryside. As the urbanization continues a large amount of the world?s population is expected to live in urban settlements of informal character by 2050. Green Belt has for many years been used to control urban growth and to secure the sustention of larger green areas around towns and cities.

Grönstrukturens dilemman i fysisk planering : Hur fungerar målstyrningen av grönstrukturen i praktiken?
To reach an Ecological Sustainable Development, Sweden has established environmental quality objectives. Green spaces are attractive for exploitation and in Sweden the access to large jointly green spaces has decreased, which has impact on humans recreation and the biodiversity. The economic aspect has great impact on the planning process which gives indications that the environmental objective may collide with other sector goals within the municipality. The thesis overall aim is to see how the management by objectives for the green spaces implements and how the green spaces is handled in the planning process in a specific case. The thesis builds on a content analysis, strategic interviews and a case study.
Regional utvecklingsplanering och grönstruktur : en studie av de gröna kilarna i Stockholms län
The aim of the thesis is to analyze the role of regional development planning concerning a regional perspective of green structure and to reflect on its future role. The target group of the study is foremost practitioners but also students of regional planning and development.
Three questions are examined. 1) What view concerning green structure has the regional planning body of Stockholm County Council (RTK) communicated through the years? 2) Has this view contributed to generating a common understanding concerning green structure among the actors in the county? 3) Has this common understanding been referred to by actors in discussions concerning how this green structure should develop?
The empirical material consists of documents from rtk, the County Administrative Board, the municipalities of the county, a network of ngo:s, as well as interviews with representatives from the above mentioned organizations.
Vindkraftetablering och uranborrning i Dalfors-Dalarna; Acceptans bland närboende
The dependency of fossil fuels has to decrease in order to reduce emissions of green house gases. Wind turbines generate electricity with low environmental impact, but the local opinion in Sweden is sometimes an obstacle to new developments. The acceptance of nuclear power increases at the same time. Mining uranium is once again on the agenda and prospectors are currently drilling for uranium. This cross-sectional study deals with acceptance of wind farms and uranium drilling.
Fordonsgas ur gödsel och vall
AbstractThe dependency of fossil fuels in the transport sector causes large emissions of carbondioxide. This problem can we reduce by using vehicle gas from digested solid manure and leftover of pasture. I have studied the potential for this in the county of Västernorrland. Thepurpose is to investigate how much vehicle gas that can be extracted.One central, large scale digestion and upgrade plant should be placed in Härnösand. Theamount of pasture and manure that is economical and practical available is enough to produce2,7-3,5 millions Nm3 vehicle gas.
Green Building : Ett företags energieffektiviseringsarbete i ett byggprojekt samt de krav som ställs för att få byggnaden Green Building klassad.
The examination has been performed at Bjerking AB, which is an architectural and engineering company. Bjerking AB has the ambition to be a member of Green Building.The Green Building program developed in year 2005 by The European Commission, the program is an environmental system with the aim to improving energy efficiency within the sectors of non-residential buildings. The minimum requirements to participate the program are following: in new-built buildings the calculated energy consumption must be 25 % lower than the requirements in the BBR (Building regulations) and in refurbishment the reduction must be 25 % lower than before the optimization.The aim of this study has been to examine and review the company Bjerking AB's energy efficiency work in the project of building the school/kindergarten S:ta Maria Alsike, where the goal is to get this building Green Building classed. A description of requirements to become a member of the Green Building has also accomplished in the thesis.The methods performed in this study are literature review, searches on the Internet, studies on the project database for facts/values, calculation of energy consumption and interviews of members of the Green Building. The following issues have been dealt with in the report;- Did the building in the project manage the requirement to achieve an energy consumption that is 25% lower than the requirements in BBR?- What technical measures/system was selected in the building?- What kind of cooperation was the project based on?- What is required for consultancy companies and real estate owners to become members of the Green Building?The study of the project and calculation of estimated energy consumption in the building, give the result 47 kWh/m2, year.
Radon i betongkonstruktioner : - Kan det undvikas?
The following article consists of two parts; one part is about house construction and the other is a specialization about radon. The house construction part describes how to project a house from start. It contains the conformation of the house, the installations needed, calculations considering the strength of the construction, energy calculation and what materials were chosen. Calculations considering the costs of building and operate the house has been carried out. The result showed that the house would cost approximately two million Swedish kroner to build and thirteen thousand kronor a year to operate.
Det Intelligenta Huset : - En studie i hemautomation
Today all buildings contain some form of home automation. It might be heating controlled by athermostat or motion detectors controlling outdoor lighting.This paper,The Intelligent House, deals with the planning of a house in Kiruna, in the north ofSweden and further immerses itself in home automation or intelligent control in single-familyhomes. The house has been entirely planned, from layout to structural design and plumbing.The purpose of the paper has been to investigate the possibilities in home automation in singlefamilyhomes and to choose a suitable home automation system for the house being planned.The system has been designed and the costs and energy savings have been calculated.The system chosen for the house is called KNX and is the largest system for home automation inSweden. It is used to control heating, ventilation, lighting and alarm systems in the house. Is hasbeen found that KNX is very expensive and that the amount of energy, possible to save in thehouse, using the system, is relatively small.
VVA-strategier för avgastemperaturhöjning på en HD-Dieselmotor
Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.
Female empowerment genom trädplantering: Hur Green Belt Movement har skapat förutsättningar för demokratisering i Kenya
Den här uppsatsen behandlar kopplingen mellan female empowerment och demokratisering. Med utgångspunkt i en maximalistisk definition av demokrati, hävdas att female empowerment är en nödvändig förutsättning för att en demokratiseringsprocess ska kunna lyckas.I uppsatsen analyseras den kenyanska miljöorganisationen Green Belt Movement:s arbete utifrån teorier om female empowerment. Kvinnor i Kenya är traditionellt underordnade männen och saknar inflytande och möjligheter att styra över sina egna liv. Inom Green Belt Movement har kvinnor fått en ledande roll och givits möjligheten att påverka sin situation. Analysen slår fast att organisationen har lyckats skapa female empowerment i flera aspekter bland de kvinnor som är aktiva i dess verksamhet.
