An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.

The purpose of this study is to give an overview about iron fortification from the view of technique and health. Example of a technical aspect is different iron compounds which are used for fortification like ferrous sulfate, ferrous fumarate and elemental iron. In the aspect of health the big question is if iron fortification can improve the health in reducing the prevalence of anemia. The study focuses on flour fortification with iron in Egypt and Iran and involves a literature study with scientific articles. Also information from WHO (World Health Organization), FAO (Food and Agriculture Organization) and FFI (Flour Fortification Initiative) are used.Fortification means an intentionally increasing of the content of micronutrient in foods with the aim to improve the food quality and deliver a nutritional benefit to the consumer.

The purpose of this study was to explore students' and teachers' experiences of the new pedagogical teaching tool, interactive whiteboard, which have gained increased popularity and wide spread usage in the classrooms. An observation during a mathematical lecture was conducted as a pilot study prior to the main research method of phenomenology; based on students? self-descriptions and interviews with two teachers, this methodological approach was used to investigate the subject matter. The interpretation, comparison and analysis of the results surrounding this new teaching method is explained by two theories, constructivism and socio-cultural perspective. The information shared by the students and teachers have been broken down into four categories: enjoyment & interest, practical, insight and no different.

The thesis also contains a valuation of the research and of the application. The valuation of the application was done by a usability test and an analysis of the results of the test.The application of the thesis has an easy navigation system, which is time saving and simple to use. Finding recipes with the associated ingredients is a quick fix. The search function can be used for searching freely after recipes as well as for separate ingredients. That makes it possible for the user to create own recipes from available ingredients.

Land management for food production is a fundamental human activity and one of the greatest challenges of the 21st century will be to increase the global food to accommodate a world growing to 10 billion or more people, while undergoing climate change. The increasing temperature and the current and projected increase in concentrations of CO2 lead to concern over possible impacts on agricultural pests. This assay is summarizing the knowledge of weeds in a changing climate in Sweden. Global warming and other climatic changes will affect the growth, phenology, and geographical distribution of weeds. The climate change will also affect the weed composition indirect by causing changes in the agriculture.

Control and comparison of various cleaning methods on restaurants in Södra RoslagenThe purpose of this report is to find out and analyze the efficiency of cleaning methods in restaurant kitchens. The investigation was carried out through unannounced inspections at 89 restaurants in Södra Roslagen (municipality of Danderyd, Täby and Vaxholm). ATP-measuring was done on a plate, a knife, a bench surface and a cutting board. The ATP-method measured the amount of food residue on equipment and working surfaces after cleaning, with a luminometer and swabs. Restaurant staffs were asked to describe in detail how and when the last cleaning was carried out on the surface.

Som en pilotstudie för Göteborgs miljöförvaltning har vi undersökt ett förenklat sätt att do-kumentera egenkontrollens kritiska styrpunkter enligt HACCP (?Hazard Analysis Critical Control Point?) -principerna för säkrare livsmedelshantering utifrån lagstiftningen som trädde i kraft 2006. Det sätt vi har studerat utgår ifrån Food Standard Agency, Englands motsvarig-het till Livsmedelsverket, sätt att dokumentera i handlingen ?Safe food better business?.I undersökningen lämnades blanketter ut till fyra offentliga måltidsverksamheter i två av Gö-teborgs stadsdelsnämnder. Dessa blanketter har sedan fyllts i av berörd personal under två veckor i samband med att de har använt sitt befintliga egenkontrollprogram för säkrare livs-medelshantering.

Sewage sludge contains plant nutrients and has earlier been utilised as fertilizer to cropland. Unfortunately not only plant nutrients but also heavy metals, pathogens and organic contaminants tend to accumulate in sludge. The suitability to use sewage sludge in agriculture has therefore been subject to several discussions over the years. The Swedish food industry does no longer accept sludge as fertiliser for Swedish producers. In 1999 the Swedish parliament accepted several objectives for environmental protection. In order to prevent environmental pollution and further exploitation of the earth crust, one of these objectives confirm that phosphorous from sewage shall be recirculated to arable land.

Cambodia is located in Southeast Asia with a tropical monsoon climate and distinctive wet and dry seasons. Poverty is a widespread problem in Cambodia and 30 percent of the population were classified as poor in 2009. About 80 percent of the populations live in rural areas where poverty is an even greater problem. In agriculture, rice cultivation is dominating and the crop is cultivated on 85 percent of the arable land. Livestock keeping is also a traditional part of Cambodian agriculture.

Insufficient intake of vegetables is a reason for micronutrient deficiencies and malnutrition in developing countries. With urbanization, globalization and a growing world population it is of major importance to secure sufficient food supply for the world?s population. Part of the solution to increased food security among the world?s poor could be the introduction of vegetable home gardens, plots for small scale vegetable production which can provide households with sufficient vegetables as well as serve as an extra income source. The study Improving peri-urban home gardens aims at examining the existence of vegetable home gardens in the peri-urban areas of Hyderabad, India.

Diet and lifestyle are closely interrelated and believed to have a significant influence on four major public diseases - cardiovascular disease, cancer, hypertension and obesity, but also affects functional deficiencies like gluten- and lactose intolerance. Health added-value foods are thought to reduce health-related risks or delay the onset of these major diseases. Therefore, interest among scientists, researchers and the public in general has been growing remarkably over the last decade regarding these special foods. The Swedish market seems to be a good target for health added-values food. However, as there are many risks and cost factors involved for companies to enter the market or invest in R&D, it is important to take a step back and analyze the current market situation.

The world?s growing need for energy together with a desire to ward off the worst consequences of global climate change has resulted in a never seen desire to invest resources in renewable energy sources. Biogas production through anaerobic digestion is one of those growing energy sources. In Sweden there are over two hundred plants that uses this biological process to break down organic substances while producing carbon dioxide and the energy-rich gas methane.This master?s thesis has focused on development of the mixture of different organic substances that is treated at a specific plant, namely Mosserud biogas plant.

Background: With the increased globalization food prices went down for a while, only to skyrocket to new levels. Prices of organic food, which already were more expensive than conventional, are now even more expensive. The current financial crisis results in reduced consumption which creates a threat to the smaller grocery stores. Globalization and the increased competition have had a negative impact on the environment but at the same time the desire to solve these issues has increased appreciably. The environmental aspect has been given higher priority by the individual, which led to a wider range of organic products and dramatically increased the number of stores selling organic products, leading to a greater competition among the stores selling organic food.  Problem definition: What factors are important for organic retail business long term survival?Purpose: Trough case studies analyze and evaluate the organic niche retail companies? strategies of marketing.Methods: This study is based on both qualitative and quantitative research methods.

Today many children have limited experiences with the outdoors or nature. In most suburbs where people originate from many countries and have various ways of understanding nature is it perhaps in preschool that several children for the first time experience nature.This survey is qualitative and the main research methods are participant observations and interviews. The theories used in this study are mainly based on the thoughts of Dewey and Vygotskij as well as on ideas from outdoor education and different ways or ideas of understanding nature.The purpose with this study is to make clear in what ways nature is used by the teachers in preschool activities and how this work is done in preschools in multicultural suburbs. Questions at issue are: What way of understanding nature are the teachers trying to convey to the children? How is nature used in the ordinary outdoor activities by the preschool teachers? What are the teachers experiences of success and problems in this work?The conclusion is that nature is used in preschool activities in many ways.

The aim of this study is to examine the understanding, preschool teachers, have about their work related to energy conversion in the human body. Through individual interviews, answers have been sought to the following questions: What do the preschool teachers believe they need to know about the link between food and energy? What are the different methods preschool teachers use to workwith the area of energy conversion in the human body?The results show that preschool teachers have knowledge in terms of food and its nutrients as an energy source for the body to cope with. However the more thorough and detailed questions become all the more uncertainty there is about the topic. Preschool teachers on their own initiative do bring up the topic with the children and begin conversations as well as ask questions, perform experiments and demonstrations.
