Carbon dioxide in the atmosphere contributes to the greenhouse effect, which is essential tolife on our planet. Furthermore, it plays an important part of the photosynthesis andrespiration of the world?s organisms. Since the start of the industrial revolution the amount ofcarbon dioxide in the atmosphere has increased exponentially. The main source is theextensive burning of fossil fuels.

The purpose of this essay is to compare two investigationprojects /evaluationproject (BBICOHPeL) regarding theoretical anchoring and operationmethods. Important questions in our research has been: What from BBIC can be found in the OHPeL-project, what has become of the fundamentals in BBIC when they have been introduced into this new context, has the ecological development theory remained in the OHPeL-project, is it possible to say that the OHPeL-project is a further development, distortion or something completely different from BBIC. To find answers to our questions we have studied 17 protocols from evaluationmeetings in the OHPeL project. This led us to the results that BBIC in many ways are present in the project. There are also differences between the projects.

Biodiversity can be described as the total variation of life forms, where diversity ranges from gene level up to the ecosystem level. The diversity can be calculated in a number of ways, and this study use one of these methods. In this study empirical food webs have been used and analyzed, where eleven characters are defined and used as parameters to calculate the Euclidean distances between food webs that describe the variation that may exist within classes of terrestrial, marine and freshwater habitats. The class who stood out and showed the greatest diversity at the ecosystem level was the marine food webs, which showed a high value of the average euclidean distance. The other networks were not as distinctive and the average of the euclidean distance in these classes was comparatively low..

Through this thesis, we want to discuss how the marginalization of people, several precedent political, city planning- and engineering decisions resulted in a catastrophic outcome after hurricane Katrina in New Orleans 2005. We also put forward a case study of the Make It Right Foundation, to demonstrate how the residents of the Lower Ninth Ward are involved in the urban development of their community. We would like to draw attention to the power of citizens and how they can influence the urban development of a community after a trauma. This study also focuses on the mission of The Make It Right Foundation: which is to rebuild the Lower Ninth Ward with firm concepts on sustainable development where all dimensions are accounted: ecological, social, cultural and economic. The empirical data was collected by a field study in New Orleans 2010-03-22 and semistructured interviews were made during the same days..

Syftet med denna undesökning var att ur ett ekologiskt perspektiv undersöka betydelsen av interna och externa resurser för integrationen för nyanlända flyktingar i Fagersta kommun, och om något upplevts särskilt viktigt för integrationen som bidragit till känsla av hopp och framtidstro. Två delstudier genomfördes. En kartläggning gjordes av lagar och regleringar som påverkar flyktingpolitiken samt en dokumentanalys av lokala policy- och styrdokument i Fagersta kommun. Åtta semistrukturerade ntervjuer genomfördes med fyra kvinnliga och fyra manliga flyktingar bosatta i Fagersta. Resultatet, som överensstämmer med tidigare forskning, visade att flyktingar behöver ges möjlighet att vara aktiva i sin egen anpassningsprocess.

The background to the work bases on the consumers view around Swedish and foreign meat products, and how the attitude around the meat products is pursued in the shops. The consumers request high meat quality and security . Many consumers value local produced and ecological meat products but the price is too high. We have done verbal interviews with consumers on three different shops, where we asked questions and had dialogues around Swedish meat products where the consumers have told us their arguments and opinions about Swedish and foreign meat. The result shows that the majority of consumers consider that it is important to know that meat is produce in Sweden.

The purpose of this study is to look at the line extensions of the Swedish dairy company Skånemejerier. We have chosen to focus on how trends in ecological products and Functional Food influence the line extensions. The competition in the food sector have made it harder for companies to be seen in the market area and the companies have to make their brands more visible. That is one of the reasons why companies work with line extensions. The study is based on a qualitative approach because we wanted to come closer to our subject in order to establish a greater understanding for the case itself.

Knowledge of ecological processes are a basis for the understanding of important environmental issues. Through qualitative interviews, 8 preschool class pupils have replied to questions concerning the concept nature, disintegration and environment. The aim of this survey was to examine what attitudes and knowledge children with different pedagogical background have about the nature and the environment.The result of this survey in whole demonstrates that all pupils have good and equivalent knowledge of the nature and the environment, independently of their different pedagogical backgrounds. A difference was however that children that have background from ?I Ur och Skur? (a Swedish outdoors preschool program) know the names of all small bugs that were in the survey.

This paper aims to examine how children who have experienced violence against their mother experience their school and if the school somehow can compensate for the vulnerable situation of the children?s home situation. The data is an already collected material there interviews with abused children are done. The results presented consist of the previous research in the area where the empirical material analyzed from the developing ecological theory and based on children's different abilities to master life and then give an voice to the collected research. The results showed that if the violence in the family does not affect the child's sleep or the parents do not prioritize enough for the child to get the sleep he/she needs and that the child is not serious difficulty concentrating, it seems that children can use school to learn and enjoy this learning.

The importance of daylight for humans has been known for a rather long time. Applying this knowledge in the science of urban planning is not very common, at least not in Stockholm, Sweden. Living in a country far from the equator with great differences between daylight and darkness during the year, daylight gets even more important for our wellbeing. This study aims to highlight the subject of daylight planning and contribute to the discussion about how to include daylight in the process of urban planning. By critically observing a new built district in Stockholm and applying guidelines of how to use daylight planning, this paper shows how important it is to include daylight planning early in the process.

The agriculture in Sweden today uses chemical substances to control vermin, weed and diseases. This usage shows through polluted subsoil water and trace elements in the food we eat. There?s a risk that additional symptoms will arise in the future. Our product Sha Jun, developed in 2006-2007, is an attempt to try and minimize the need of chemicals in the agriculture. The idea started with the attempt to minimize the usage of pesticides on the cropland.

The purpose of the thesis is to describe how environmental compensation is carried through when it comes to exploitation of Natura 2000. The thesis also relates to the three theories of planning synoptic, advocacy and transactive. Three cases of environmental compensation have been studied from three different countries where an exploitation of the Natura 2000 is done. Sweden, Germany and the Netherlands have all been working with environmental impact assessments as a demand to be able to carry through their projects. The projects concern the development of a railway track, an industry and a port which all have been approved by the EU-commission to carry on because of socioeconomic reasons.

Biological diversity is one out of four dimensions, characterizing the subject of Biology ac-cording to the school curriculum. As a concept, biological diversity had its break through at the UN environmental conference in Rio de Janeiro in 1992, where the convention about bio-logical diversity, named CBD, was signed. According to the convention, almost all the na-tions of the world have engaged themselves to preserve the national diversity of species, in-cluding the diversity of genetics and ecological systems.This thesis focuses the biological diversity from the perspective of school books. The aim is to find out how the biological diversity is presented in biology books for students aged 12-15 years.In 1994, the current Swedish secondary and high school curriculum called LPO-94 was pre-sented. The biology books used in this study were published between 1994 and 2007, all of them exist in many editions and are published by three different publishers.The conclusion of the study is that all the biology books that were examined have reached different levels of the development in the field of biological diversity..

The intention with the study is to describe the home and life conditions for boys at the age range between 13 to 18 year, who has been under custody according to the § 2 LVU.The empiric is 21 real court cases, judged in Stockholm and to Stockholm counted surround-ings 2006, in which the range of the boys were representative.A text analyze method is used to execute the study. The study penetrates the life situation of the caregiver and how their situation affects the boy and the boys actions.The total conclusion of the study, based on an ecological evolution perspective, is that life-situation of the caregiver affects the boys and the boys actions.The boys are affected negatively by the situation of their caregivers, and according to the study, the boys have established own problems, like difficulties in school, criminality, or other psychological diagnoses. They are also often exposed to physical or psychological violence by the caregiver. Additionally the conclusion is that the caregiver neglect the boys in many other ways, prior themselves and their needs before the boys..
