Vattenkvalité i Märstaån : Igenväxning som indikator på närsaltläckage och vattenstatus
The purpose of this study was to examine whether an inventory of the vegetation overgrowth could be used to indicate a locally nutritional impact. The study was conducted at Märstaån where the water runs through a number of agricultural lands that could lead to an increased amount of diffuse emissions of nutrients. The vegetation overgrowth in the water was also studied in relation to shade, meandering and water flow effects on the vegetation. With this method, no definitive conclusions could be drawn.Where the water was shaded, no vegetation overgrowth could be found. Therefor trees should be planted to prevent any future overgrowths.
Facket och de papperslösa arbetarna
In the beginning of 2002 a new kind of debate started inside the Swedish trade unions that also were published in the newspapers. The debate was about if the Swedish trade unionshould organize the undocumented workforce or not. In this thesis I will deal with this issue and also investigate what kind of solutions the trade unions in Sweden use on this newphenomenon, a phenomenon that recently have become a social and political problem during the last years. This is a new subject within political science and there is limited research made before. Because of that, this thesis will be empirical, inductive and exploring by its nature.
Hållbar vattenplanering : en diskussion med utgångspunkt ur fyra bristområden
Billions of children, women and men lack access to safe water supplies, whichputs the affected in both social as well as economic despair. This paper willpresent some of the conclusions leading Non Governmental Organisations suchas the UN has presented recently concerning the terms of sustainability. Much ofit is true and important, but nothing can be done without extended cooperationbetween nations worldwide to find arguments that prevent short-term thinkingand economic wealth on the behalf of future sustainability.With a growing population and an increased competition for fresh water, theworld will soon face a severe shortage of good quality water for irrigation. This isbecause the distributions rarely match the demand, neither in Australia nor inAfrica. Important to notice is the major factor that the degradation of theenvironment is not one country?s problem to solve.
Irrigation scheduling for efficient water use in dry climates
In this report the importance of irrigation scheduling in dry climate is shown, how it can save water and energy; how this method can improve crop yield by supplying the right amount of water at the right time. It is shown how irrigation scheduling and irri-gation technology together increase the irrigation efficiency..
Vatten som säkerhetsfråga : Med FN:s konstruktion av vattenfrågan som utgångspunkt
ABSTRACTThe aim of this study is to analyse if the UN today constructs the water issue as a security issue and to argue about in which way the organization in that case does so alternatively why it can be said that the UN doesn?t construct the water issue as a security issue.In order to reach this purpose the following questions will be answered:?Does the UN construct the water issue as a security issue today?-If yes, in which way?-If no, why can it be said that the organisation doesn?t?The methods used are qualitative literature studies of policy documents on water from the UN. The focus is to analyze the ideas about water and to apply my theory on the concept of security, which is Barry Buzan?s framework on security, to these ideas.The main results showed that the UN strongly constructs the water issue as an environmental security issue for environments and species and in relatively strong terms also constructs it as an environmental security issue for civilisations. In rare cases the organisation constructs it as a societal security issue, but the UN doesn?t construct the water issue as a military, political or economic security issue..
Hållbart nyttjande av vattenresurser på Gotland : vision och verklighet
Fresh water has become more and more of a scarce commodity. Water scarcity isn't first and foremost a cause of drought and wasting, but a cause of inequality and mismanagement. This is not only a problem for developing countries, and there can also be variations within countries. The municipality of Gotland has a development program called Vision Gotland 2025, with goals for growth and sustainable development. The aim of this study is to examine whether the use and management of water resources on Gotland and Vision Gotland 2025 is conformed to the Water Framework Directive and the Ecosystem Approach in terms of sustainability.
Dubbelkönighet hos mört : normalt eller miljöinducerat?
A number of chemical agents, and their degradation products, have been
recognized as having estrogenic activity on animals. On fish they interfere with
endogenous estrogen and in many cases mimic its activity, thus increase estrogenic
reponse, with elevated levels of vitellogenin. Hence they are called Endocrine
Disrupting Chemicals, EDCs. Vitellogenin levels is often used as a biomarker of
exposure to estrogenic pollutants. Wastewater from sewage treatment works
contains chemicals known as EDCs, and there are evidence of roach (Rutilus
rutilus) living in recipients of such wastewater having traits of both gender, i.e.
oocytes in male gonads (intersex) on histological examination.
This study was done on roach living in Lake Funbosjön Uppland, Sweden.
Sverige och implementering av EU-direktiv : En fallstudie av badvattendirektivet och arbetstidsdirektivet
The aim of this paper is to explain and compare non-compliance of two EU-directives, ?the quality of bathing water? and ?the working time directive?. This study answers the questions: Why didn?t Sweden implement the directive on bathing water quality and the working time directive correctly? Are the reasons for non-compliance the same or different in the two cases? The paper is designed as a case study and with an explanatory attempt we explain why the two directives weren?t implemented correctly in Sweden. The theoretical approach is based on both general- and EU-specific implementation theories.
Vattnet i vår kropp : Förskolebarns tankar om vattnet innom oss
AbstractThis study deals with preschool children's ideas about water in our body. Ten children with the age of four to five were interviewed individually, the interviews were qualitative. The children were also asked to draw their answers and answer questions about a picture that represented the excretory system. The results of my study show that children did not have any knowledge about the water being vital for us. Preschool children had no knowledge of why it is important to drink water.
Om associationer till vatten
This paper is intended to provide a picture of which associations water can wake in the human
mind from the perspectives of garden history as well as from that of environmental
psychology. I hope to paint a fairly broad picture of our perception of water that can serve as a
basis for discussion and as a starting point for different forms of design work in landscape
architecture. The historical perspective emphasizes the importance of water as a condition for
the emergence of gardens and in a wider perspective the importance of water in early cultures.
Also, I describe a picture of how water has been used throughout the history of gardens from
early Egypt to the baroque era. The garden history analyzed from an art historical perspective
gives a picture of human associations to water, and the history behind these associations is
presented. As a compliment to the art history approach, I have chosen to highlight our
associations with water from the perspectives of environmental psychology and evolutionary
science.

The water company MittSverige Vatten (?MidSweden Water?) located in the Medelpad, Sweden was in need of a moreexclusive water carafe for restaurants and conference in the region. Current design solution was not able to cope with thedemand of a more exclusive setting and was not promoting the company in a good way. In the beginning of the projectit became clear thru an intense interview period that there was at least three directions for design solutions the companycould go for.? A carafe (exclusive settings)? A pitcher (conference and lunch servings)? A water dispenser type (serving of larger amounts of water during a certain brief periods of time.)It was decided to go for the exclusive one.Small pieces of rock from the last ice age turned out to be a vital component of the new design concept for the company..
Fair Trade - en litteraturstudie med fokus på premien
Uppsatsen sammanfattar nationalekonomiska teorier kring fair trade och, för teorierna, relevant empiri. Störst vikt läggs vid fair trades prismekanism och vilka effekter samt bieffekter den innebär. Teorikapitlet består i princip av fyra delar; Premiens konsekvenser i effektivitetshänseende. Rational choice, om incitamenten att delta i fair trade. Därefter en handelsteoretisk jämförelse mellan fri handel och fair trade i heckscher-Ohlinmodllen.
Rättvisemärkning av snittblommor på den svenska marknaden :
Trade is the driving force for economic development. A greater equity in international trade can improve the livelihoods and the well being of producers in developing countries. The small-scale farmers have limited resources and have difficulties to get access to the international market. As a result of this, the Fair Trade movement has been developed and has now formed a trading partnership between the producer and the consumer.
This study analyses if the Fair Trade movement can be a way for the workers in developing
countries to achieve more justice in their production manner in the international trade of cut flowers and continue to be an important competitor of these products, but with better livelihood conditions. My method has been to do a comprehensive literature study of the Fair Trade movement, in which I describe the certification process, and the market of Fair Trade in Sweden.
Ansvarsfrågan vid fuktspärrsarbete i våtutrymme
This final project is an investigation about the responsibility in rooms where the walls and floors are exposed or partly exposed to irrigation of water, as a bathroom, laundry room and WC. The cost for all water damage is valued for 5 000 000 000 SEK each year. How is this possible with all information about the problem and good materials? Who is responsible? Incites had been made in the subject throw reading reports and participation in courses about how to make a room mention above. Discussions have been made with workers in the trade of making the walls waterproof.The conclusion in the rapport is about who´s responsible for the damages and will pay the cost of the renovation. The responsibility is discussed between the contractor and the insurance company.
Hållbart jordbruk inom vattenskyddsområde : En studie om Sverige, Danmark, Frankrike och Tyskland
To guarantee protection of our drinking water, water catchment protections are established. These are divided into three different zones and in the first zone it is most likely that an activity, such as agriculture, will contaminate the water resource. Hence the activities are strongly regulated or banned. The EU communion is working towards a sustained water quality through several directives; Nitrate Directive, Waterframwork directives and Sustainable use of pesticide directive. The main purpose is to regulate the diffuse pollution from agriculture.This thesis is about how Denmark, Germany and France are working towards a sustainable agriculture within water protection areas.
