För den goda sakens eller smakens skull?: En studie om vad som driver konsumenter i valet av ekologiskt vin

Concerns for the environment and our impact on it are becoming more prevalant; however, we rarely act accordingly. Consumers mainly choose products based on perceived personal benefits despite the environmental motives that increasingly affect them. The purpose of this thesis is to identify the major drivers behind the purchase of ecological wine. A quantitative study was conducted, using Theory of Planned Behavior (TPB) as an initial starting point. The subsequent model was then completed with three variables: environmental concern, feelings and word-of-mouth.

In-store retail environment ? A study if placement of ecological products has an impact on sales and attitudes towards buying.

The purpose of this thesis is to investigate whether placement, using a special display, of ecological products, will have an effect on consumer buying behaviour and thereby sales of these products. When talking about sales we refer to the amount of ecological products that are being bought, habitual and unplanned, as a response due to the placement of the products in-store. To further elucidate the purpose, the thesis will focus on if the placement of the products itself will have an impact on the customers? attitude towards buying ecological products. A deductive approach was applied where we did a quantitative study using triangulation to receive data to reveal if the placement of ecological products had any effect on the sales of these products.

Evaluation and Comparison of Ecological Models Simulating Nitrogen Processes in Treatment Wetlands,Implemented in Modelica

Two ecological models of nitrogen processes in treatment wetlands have been evaluated and compared. These models have been implemented, simulated, and visualized in the Modelica language. The differences and similarities between the Modelica modeling environment used in this thesis and other environments or tools for ecological modeling have been evaluated. The modeling tools evaluated are PowerSim, Simile, Stella, the MathModelica Model Editor, and WEST. The evaluation and the analysis have been performed using McCall?s factors for software quality (McCall et al, 1977), a correlation analysis and the Constant Comparative Method (Glaser&Strauss, 1999).

Den gröna konsumentmakten - medborgarens ekologiska insats

The aim of this thesis is to form a theory of the green consumer power and to distinguish whether this phenomenon could indicate a movement toward the ecological citizenship. To do so, scientific theories regarding the responsibility of companies have been used, as well as the public choice theory, to link individuals as citizens to individuals as consumers. The motives of corporate environmental responsibility, along with consumers ability to bring pressure in different dimensions, are later drawn on as indicators applied to empirical information. The largest producer of ecological products in Sweden, Arla Foods, is employed as case study to explore if the green consumer power can and does exist. The ecological citizenship uses the ecological footprint, to define in what ways we can minimize our part of environmental degradation.The study seems to strengthen the theory, consumers do have a power to make companies go green and they tend to use it increasingly.

ISO14001:2004 : ett humanekologiskt verktyg?

ISO14001:2004 : A Human Ecological Tool?This is a study by means of litterature analysis and personal experience to find out wheather you could call ISO14001:2004 a Human Ecological tool. The ISO14001 is an environmental management system. I'm approaching the issue from a users' perspective and putting my experience of implementing the ISO 9001 at my work to good use. Though my personal experience is limited to the implementation of the ISO 9001, it is quite relevant to the task since the update of 2004 the ISO14001:2004 is brought closer to the ISO 9001 standard in many ways.

Re-design of Toledo Riverfront : from industrial past to sustainable biodiverse future

Effects of climate change, urbanization and global homogenization are resulted in the degradation of land and losses of natural habitats. Ecological design integrates nature into urban environment by respecting natural ecological principles and processes and creating resilient urban biotopes which also can be used by local urban communities. The aim of the thesis is to answer the research questions: How ecological design principles can be applied for re-design of Toledo Riverfront (with requirements of the design competition)? and What is the ecological design in landscape architecture? I participated in the USA design competition with the aim to create a vision and redesign of Toledo Riverfront in Ohio State, USA. The site is located in the south point of Lake Erie. As a result of a long industrial activity, riverfront of Toledo had been transformed into inaccessible and abandoned brownfields. In my proposal I applied ecological design principles on three scales: the city of Toledo by reinforcing of ecological connection and creating green corridors along the river; the intermediate scale by suggesting public parks along the river front and on the fine level by proposing detailed design including remediation of the site and use of dredged material.

Socialt arbete och hållbar utveckling, hur då? : En kvalitativ studie om socialt arbete och hållbar utveckling i två arbetsintegrerande sociala företag.

The aim of this study was to examine how two integrating social enterprises relate to and combines social, ecological and economic sustainability and how they work with sustainable development in the field of social work. The study has been focusing on three questions: What are the values underpinning ?Macken? and ?Vägen uts? approach to sustainable development? What motivates these companies to work with ecological sustainability in the creation of new jobs? How do these companies combine social, ecological and economic sustainability? To answer our questions we have been interviewing nine employees through semi-structured interviews combined with observations and this study was analysed through a symbolic perspective. The conclusion of this study showed that these companies worked with specific themes to reach social sustainability. Recurring themes in the study was empowerment, recovery and the employee?s own experience of exclusion.

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.

Ekologisk dagvattenhantering på parkeringsytor : Lösningsförslag för Eurostop köpcentrum i Halmstad

Stormwater from trafficked areas often contains high pollution levels. In traditional stormwater management design, stormwater is first transported away through piped networks, and then in most cases passes through oil separators before finally reaching the recipients. While this traditional method removes certain pollutants from the stormwater, it does not reduce the total flow, as in the case of ecological stormwater management. In the ecological method the stormwater is not simply transported away, but is recirculated through infiltration, percolation, and detention. The aim of this study is to investigate possible advantages of ecological management designs, in contrast to traditional management.

Självbild: påverkan och motståndskraft ur ett utvecklingsekologiskt perspektiv

Our paper is a study about youth and their self-images. During our practical training period we found that the problems young people had always were connected with their self-image. We therefore wanted to find out what youth believe influence their self-image. The purpose of our study was to examine young people and their self-images in a perspective of the ecological systems model. Essential issues have been what self-images young people have, what they consider influence their self-image most, how they think they can resist influence from the environment and how they would like to be influenced by the environment if they could decide themselves.

Från miljövård till hållbart samhällsbyggande - Förändringar i den Svenska miljöpolitiska diskursen under perioden 1987 - 2005

The aim of this thesis is to study discursive change in the Swedish environmental political discourse between 1987-2005. The text of three Swedish budget propositions are analysed for this purpose.The results from the analysis are related to a few relevant theoretical perspectives that hold partly different views on what constitutes ?sustainable development? and ?ecological modernization?. Through these theories the thesis continues the discussion around the two central but somewhat blurry terms sustainable development and ecological modernization. The aim of this discussion is to conclude whether the discursive change in Swedish environmental politics can be said to go more in the direction of sustainable development or ecological modernization, or if elements of both perspectives can be found.The analysis shows that the Swedish environmental discourse has come to include more and more political fields such as general welfare politics, during the period.

From industrial past to sustainable future : Arboretum Lövholmen; generating trees for a greener future

Old industrial sites bear witness of the unsustainable industrial developments in the past. Today many of them stand abandoned and empty, old structures lacking function in our present society. We have in this thesis participated in a visionary student competition arranged by IFLA, International Federation of Landscape Architecture by developing a proposal based on a vision of how Stockholm can stimulate a greener development. We have done this by turning an unsustainable industrial site in the city into an ecological node; Arboretum Lövholmen. Our aim is to develop an entry for IFLA?s visionary student competition by creating a new sustainable design for the industrial area of Lövholmen in Stockholm. We have worked with the following research questions: How can we create a visionary design proposal for Lövholmen that promotes sustainable development with the help of ecological design? How can the competition format be a design tool? How can the working process developing a competition entry progress? The competition demands have shaped our working process and functioned as a platform for the structure of this thesis.

Gröna broar : ekologiska, sociala och estetiska tillgångar

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.

Massbalansmodellering av fosfor i ett åländskt kustområde : en utredning om lokaliseringen av Lotsbroverkets utloppsledning

This report is commissioned by the Water and Sewage Agency in The City of Mariehamn, Åland. The basic aim is to investigate positive or negative effects of a relocation of the sewage pipe from a wastewater treatment plant, Lotsbroverket. The environmental licence of Lotsbroverket is to be revised and The Environmental Appeal Board at Åland?s Government and Administrative Board has made demands that several possible locations in an outer water area should be examined. The present location of the sewage pipe is in Svibyviken, which has been classified as an ?inner water area?.The objective of this work is to study to which extent the nutrient loading from Lotsbroverket influence the environmental conditions in Svibyviken, and to investigate the suitability of different locations of the wastewater pipe from Lotsbroverket.The way a coastal area looks, i.e., its morphometry, determines to a large extent its ecological characteristics.

Sol, jord och vatten. : Barns tankar om den ekologiska processen

Studies show that the interest and knowledge about science among teenagers is decreasing. They also reveal the difficulties to explain the ecological processes and that the ideas about the nature are collected from everyday life and early school years.The intention of this investigation was to find out more about children?s ideas and knowledge about the ecological processes and to compare these results with the curriculum.The method was a questionnaire and interviews with children in school year 1 ? 6. The aim of the studies was also to find out if any progress connected to age could be found, concerning understanding of the ecological processes.The results showed difficulties in achieving the predestined goals for biology and chemistry concerning ecology cycles and they differed a lot between the children. Often the learning process showed very little progress.
