About 30 % of our Greenhouse gas admission comes from the food we are eating, and food plays a crucial role in the choice of destinations. The tourism industry has a great opportunity to affect our food habits. Used in the right way, the industry can teach us to eat more environmental friendly..

The City of Stockholm has decided to invest in renewable energy and especially in photovoltaics. The objective of this thesis is to investigate the photovoltaic potential on roof areas that the city possesses and to further investigate some buildings of the Property Management Department. The thesis also compares some existing photovoltaic plants with the solar irradiance map which shows available roof area on each building in Stockholm. The report ends with a literature study about the climate impact and Greenhouse gas emissions of photovoltaic.The total available roof area suitable for photovoltaic plants is estimated to 700 000 m2, with a potential electricity production of 110 GWh per year. This corresponds to 17 % of the City of Stockholm?s yearly electricity consumption.

Hylocomium splendens (Glittering wood-moss) is a common species in the Nordic countries and can be found in many different types of boreal forests. It usually forms dense moss carpets on the forest floor. The shoots grow in segments and new segments form annually on the previous years growth. The size of the segments is probably regulated in a high extent by local micro environmental conditions. Previous experiments suggest increased growth of H.

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.

There are two species of potato cyst nematode (PCN), the yellow, Globodera rostochiensis, and the white, Globodera pallida. Each of them can appear in different pathotypes. These are separated by testing the nematode ability to multiply on a number of potato cultivars with different resistance properties. The aim of this project was to examine the virulence of Swedish and foreign PCN populations and to compare two test methods. Biotests are today the only available tests used to study virulence.

Environmental issues and ecology is something that is discussed by the Climate board of the UN and by our Swedish politicians. The first part of the thesis deals with the effects of emissions of Greenhouse gases in our atmosphere. There is a discussion about what counts as Greenhouse gas. Interviews have been made with two growers of annual plants and one interview with a person who has worked hard to increase the use of perennials in his work place, Mjösund?s cemetery.

Gerbera jamesonii is a plant with a large amount of pollen and various flower colours and a favourite host plant for Frankliniella occidentalis. The best growing temperature for gerbera is approximately 20°C. Frankliniella occidentalis or the Western Flower Thrips is a small insect that has become an important pest in greenhouse cultivation all over the world. The high temperatures in the greenhouse are favourable for F. occidentalis.

The aim of this report was to quantify the accumulation of carbon dioxide (CO2) and methane (CH4) in ice-covered lakes in winter (October-March) during three consecutive years, and to assess whether the concentrations of DIC and CH4, as well as the ratio DIC:CH4 differs between years and between lakes affected by clearcutting and untreated reference lakes. Water- and gas samples were collected from four boreal lakes (two affected by clearcutting and two untreated reference lakes) located in Västerbottens inland in spring. The lakes were found to accumulate on average 91, 55, and 84 mgCm-2d-1 during winters 2012-2013, 2013-2014, and 2014-2015, mostly originating from CO2. The concentrations of DIC (autumn and spring) were higher in the affected clear-cut lakes compared to reference lakes for all years, including the reference year (2012-2013) before clear-cutting. No such difference was found for CH4 or the ratio DIC:CH4.

Considering that the price and demand for energy gradually has risen over the past decade and a wider discussion about the human impact on the environment has become increasingly more important and given a clearer role in modern society. This has contributed to increased incentives to reduce the use of fossil fuels and increase the use of renewable energy.The agriculture currently accounts for 20 % of Sweden's total Greenhouse gas emissions. A way for an agricultural company like Wapnö AB to reduce their emissions could be to utilize existing renewable energy sources within their own premises.The report's aim is to create an energy audit of Wapnö?s existing energy system and how it changes with a future biogas plant in operation. The energy audit is used to illustrate how the company?s climate footprint could change.

The purpose of this study was to describe the possibility of implementing a lacto-ovo-vegetarian and organic diet in Eskilstuna municipality?s public preschool. Furthermore the purpose was to identify and describe the most important components involved in the implementation and their influence in the process.  The methods used were a survey based on a literature study. This study includes general information about meat production and consumption and also the use of pesticides in farming. It also brings up the environmental and health effects caused by the previously mentioned areas.

Mankind faces a serious threat. Its activities, for example the burning of fossil fuels, have led to an enhancement of the greenhouse effect - something that has given rise to a global warming. The climate is becoming warmer, a change that has important effects on the nature as well as for humans and their society. Sea level rising, extreme temperatures are becoming more common, glaciers and other ice caps melt and storms becomes more intense when they appear. The main cause is the emission of Greenhouse gases into the atmosphere - carbon dioxide in particular.

The purpose of this study is to create a method that can be used to produce decisionsupport data for the climate goals of a municipality. The method should be able to demonstrate the potential for reducing energy use and Greenhouse gas emissions for measures aimed at the stationary energy system in the municipality. It will be used to make longterm projections of energy use and Greenhouse gas emissions in order to be able to demonstrate the ability to reach climate goals. The aim was also to test the method's applicability by using the municipality of Uppsala and the Uppsala climate protocol project in a case study. Uppsala climate protocol is a project consisting of participants from business, government and organizations that voluntarily want to commit to reducing their carbon footprint by reducing their energy use and thus work to achieve the municipality's overall climate goal. Public reporting of energy use and climate impact has been studied in order to examine the nature of indicators and accounting figures that are commonly used in the field and how long-term forecasts are formulated. In connection to this, the type and sources for the kind of data needed was also examined.

The effect of methyl jasmonate on resistance against the large pine weevil (Hylobius abietis) in Scots pine and Norway spruce seedlings. A field experiment was conducted in order to determine the dose-response effects of methyl jasmonate (MJ) on growth and defence to pine weevils in Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) and to compare the effect of MJ between pine and spruce. In addition a complementary greenhouse experiment was conducted with the same aims as above and to determine the amount of resin ducts and their correlation to the feeding of pine weevils. The field experiment was conducted on a fresh clear cutting in Garpenberg, southern Dalarna in central Sweden. The experiment consisted of 30 blocks with three kinds of containerized seedlings: 2-year old spruce, small pine (before shoot elongation) and 1-year old pine (already shoot elongated). They were all exposed to 4 treatments 14 days prior to the experiment: control, 25 mM/L MJ, 50 mM/L MJ and 100 mM/L MJ. Data on weevil damage and seedling growth were collected after the first and the second growing season. The seedlings in the greenhouse experiment were of the same kind and were exposed to the same treatment as the ones in the field experiment.
