Kläder i hampa - ett miljövänligt alternativ/komplement till bomull?
Hemp has been used for textiles for a long time in history until it became illegal to grow in many countries in the 1930s. It is interesting from an environmental point of view because it doesn?t need any pesticides and in most locations it doesn?t need any irrigation either, compared to cotton, which normally requires big amounts of both pesticides and water for irrigation. Hemp is a bast fiber, which means that the fibers are located on the bast of the stem (on the outer layer of the stem). Therefore they cannot be spun directly, they have to be removed from the stem first.
Aquaculture : animal welfare, the environment, and ethical implications
The aim of this review is to assess the ethical implications of aquaculture, regarding fish welfare and Environmental aspects. The aquaculture industry has grown substantially the last decades, both as a result of the over-fishing of wild fish populations, and because of the increasing consumer demand for fish meat. As the industry is growing, a significant amount of research on the subject is being conducted, monitoring the effects of aquaculture on the environment and on animal welfare. The areas of concern when it comes to animal welfare have here been divided into four different stages: breeding period; growth period; capturing and handling; and slaughter. Besides these stages, this report includes a chapter on the current evidence of fish sentience, since this issue is still being debated among biologists.
oikos ? nomos eller logos? : Hållbar utveckling och ekonomi i gymnasiets samhällsböcker
This paper contains an analysis that sets out to investigate how sustainable development is portrayed in textbooks used in gymnasium level civics education. The study covers three textbooks, all in current use. The paper sets out to explore the relationship between the books chapters on economics and those about environmental issues. The sum of these two parts is in the context supposed to make up the books big picture of green sustainable development, i.e. the ecological aspect of sustainable development. An analytical model will be used to categorise and compare the three textbooks.The method chosen for this is analysis of ideas by use of ideal types.
Skönlitteratur for slukaråldern Ur ett vuxenperspektiv: Några barnbibliotekariers och grundskolelärares syn på barnlitteratur.
The aim of this master's thesis is to investigate how adults and especially children's librarians and intermediate level teachers experience children's literature. The aim is also to examine how children at the age of nine to twelve experience the literature that is written for them, according to a few master's theses written at Bibliotekshögskolan in Boras. Which criteria in children's books do the different groups consider as the most important, that the children can learn something when reading or is it the experience of the literature itself that is the most important? To fulfil the aim of this master's thesis I have interviewed three intermediate level teachers and three children's librarians and the result has been analysed using a model created by Maria Nikolajeva that shows four ways to get close to children's literature. My study is too small to be counted as a general result but it shows that both the children's librarians and the intermediate level teachers mainly ends up in the field that concerns the reading experience one can have when reading fiction.
Eco Screening : Framtagning av ett verktyg för kartläggning och utvärdering av produkters miljöbelastning vid ÅF EcoDesign Center
The report describes an ecodesign thesis performed by the author at the ÅF EcoDesign Center. The basic idea of ecodesign is to develop products with a minimized environmental load, without neglecting other significant product aspects such as function and price. During the last couple of years the public interest in environmental friendly products has increased, which has made it possible for companies to make a profit from their investments in ecodesign. To meet the increasing market for ecodesign services ÅF started the ÅF EcoDesign Center, where the company has gathered all of their competence in ecodesign in order to help companies to become greener. The task was to develop a tool for an Eco Screening.
Produktionsvåtmarker mot övergödning
In ambition to produce more and better harvests, artificial fertilizers are used to produce a better growth of crops in the agriculture landscape. This contributes to leakage of nutrients. Our forests also exhibit a leakage of nutrients. Air pollution contributes to more nutrients. High precipitation with high water flows as a consequence seems currently to occur more frequently in the county of Halland.
Studie av miljökonsekvensbeskrivingar till detaljplan : En jämförande analys av fyra MKB
When the local authorities establish a plan for land use planning, they have to judge if the influence on the environment could be of such a grade that they have to make a special Environmental Impact Assessment (EIA), following national laws and EU-directives. The laws for the process in Sweden is set by the Swedish Parliament, with advisory given by the central government authority, the National Board of Housing, Building and Planning, Boverket. For EU, the laws is set by the European Parliament and the Council. The laws and directions for this process have been changed for Sweden in recent years, and the aim of this study was to compare the contents of three different Environmental Impact Assess¬ments to see if there has been any change in appearances and content in later years, as well as to see if different municipalities and authors have effect on the EIAs. According to different studies some of the EIA done are without insufficient focus on main environmental issues in the EIA, or even that some information is missing.
Färden till hållbarhet : en studie kring påverkan och ansvarstagande för en hållbar turismutveckling i utvecklingsländerna
The purpose of this dissertation is to describe and analyse the effects of tourism in developing countries and the attitudes and working methods of Swedish tour operators towards sustainable tourism. We have chosen to use a qualitative research according to a hermeneutical view. We have carried through in-depth interviews with eight tour operators. The theories have been divided into the effects of tourism and sustainable tourism goals which have social, economic and environmental starting points. The empiricism describes the work and activities of the tour operators and compiles the interview material divided into attitudes on tourism effects and responsibilities.
Mobility Management : vad är det?
Mobility Management is about affecting and changing the demand of mobility. It?s not about what traditional planning?s been focused on; to supply for the demand. The demand of mobility is created by us humans since the traffic exists of us. That means that Mobility Management is about changing our needs.
Sammankoppling av fjärrvärmenäten i Nyköping och Oxelösund : miljö- och systemkonsekvenser
District heating covers most of the residential areas and industries in the twoneighbouring Swedish municipalities Nyköping and Oxelösund. In Nyköping,Vattenfall AB Värme produces heat in a bio-fuelled CHP plant. In Oxelösund,waste heat and use of waste gases from the steel production at SSABOxelösund is the basis in the district heating system.This report examines the environmental consequences of a connection betweenthe two district heating systems. A broad system approach is used and the focusis on environmental effects in the system.A system analysis has been performed on the result of simulations of differentheat and electricity production alternatives. The alternatives simulated wereone where Vattenfall Nyköping covers the base load in the joint district heatingsystem and two where the power plant at SSAB Oxelösund supplies the heatbase load.The conclusion in this report is that the consequences of connecting the twodistrict heating systems can be both positive and negative, depending onsystem boundaries and on the environmental focus.
Factors for success in Swedish biogas : a study based on the Swedish agricultural sector
The energy sector of modern time is currently faced with several challenges. These are both production oriented and environmental oriented in nature. The energy of the future is intended to support an increasing demand while at the same time reduce its environmental affection. This stresses a development towards production methods of renewable energy. Among the existing methods, biogas is presented as an attractive alternative.
Inventering och bedömning av förorenade områden inom division Energi, Tekniska Verken i Linköping
This thesis was commissioned by Tekniska verken, Energy Division with the overall aim to investigate the concept of environmental debt and what it means for a business. Furthermore, a sustainable risk and responsibility investigation shall be carried out on the concerned areas. Finally, the priority areas shall be highlighted and proposed actions presented. The Swedish Environmental debt concept was presented in 1992 by Arne Jarnelöv. Environmental debt is defined as restoration costs for environmental damage. In the early days the concept did not take into account who was responsible, but the environmental debts was regarded as a humanity debt to future generations.
Psykologiska mekanismer och miljöperspektivet - sambandet mellan attityder och beteendeintentioner inför samhällets miljöpåverkan
Syftet med studien var att pröva vilka psykologiska mekanismer som påverkar
sambandet mellan attityder och beteendeintentioner inför miljöpåverkan hos
individer i konsumtionssamhället. Hypotesen var att det finns ett
miljömedvetande hos människan, men att det är en skillnad mellan attityd och
beteendeintention.
Även emotioner inför miljöpåverkan hos deltagarna undersöktes, för att fördjupa
studien. Undersökningen har gjorts kvantitativt via en webbaserad enkät, genom
utskick via Facebook till vuxna individer i Sverige mellan 18-65 år (N=49).
Svarsprocenten var 46 procent. Huvudresultatet visar att det finns en oro hos
individer inför miljön och framtiden och 94 procent av deltagarna anser att
miljöfrågor är viktiga.
Hållbar utveckling i kommunalt beslutsfattande : En studie om integrering och prioritering ur fritidspolitiskt perspektiv
The concept of sustainable development is a challenge that demands cooperation from all levels of society for it to be successful. The focus for this thesis is how politicians within the local councils understand the concept of sustainable development and how they implement it in political decision-making.The basis for the study is a questionnaire that was distributed to 303 local politicians in three municipalities of varying size in Southern Sweden. The study concentrates on departments within the local councils that are directly connected to the Swedish environmental law and the Swedish planning and construction law. One of the primary goals with the aforementioned laws is the achievement of sustainable development within one generation.The outcome of the study was that over half of the local politicians could correctly define sustainable development according to the World Commission on Environment and Development?s (WCED) definition.
