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.
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.
Analys av vattenkvalitet i ett kommunalt badhus
Bath has been a part of human history for a long time. Today bathing/swimming inmunicipal pools is for people of all ages and it is possible to take swimming courses,exercise or enjoy recreation. The municipal indoor pool of Hogdalen in Sweden wasbuild in the sixties and has had problems with high levels of heterotrophic bacteria. Thefacility has two larger pools, one adventure park for young kids, two smaller bath tubsand a jacuzzi. To improve water quality UV light and coal filter were installed inOctober 2009 to the already existing purification system.
Serveringskärl för restaurang
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..
ENERGIÅTERVINNING I GRANSHOT® - PROCESSEN
Uvån Hagfors Teknologi AB (UHT) has developed a process ? GRANSHOT® ? for quicksolidification of metals in water baths. In the process liquid metal is splintered ? granulated ?into small drops. The drops are rapidly cooled in a water bath where all the heat energy from theliquid metal is transferred into the water.
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.
Mälarens vattennivå i ett framtida klimat
The discharge from Lake Mälaren is regulated to keep the lake water level within limits set by a water decree. Despite this, in the year 2000 the lake water level rose above the upper limit. Studies conducted at the climate modeling unit Rossby Centre at the Swedish Meteorological and Hydrological Institute (SMHI) indicate that the inflow to the lake may increase in the future. A flood in the area will, among other things, strike infrastructure and residential districts.The aim of this study was to investigate the water levels of Lake Mälaren in future climates. In addition to this possible future expansion of the lake discharge though the sluice gates in order to keep water levels below limits set by the water decree and to prevent flooding of the shoreline were discussed.
Utveckling av omrörningsenhet
The use of technology in today's society is frequent and often necessary, but how, when and where are we supposed to learn how to use it? And if it is such a big and important part of our society, then why don?t teachers get more training in how to use the technology? The purpose of this paper is to examine whether teachers attitudes to technology affects their use of technology in their teaching. In school technology can be a complementary to other material, if teachers have the necessary skills to use technology in a pedagogical way. I have chosen to do a qualitative study in form of interviews and observations at a school outside of Stockholm. The results show that both school and teachers must want to work with technology if anyone will be getting something out of it.
Anva?ndning av markfuktighetskartor fo?r sta?ndortsanpassad plantering
Digital depth-to-water maps can be produced from a digital elevation model (DEM). Then GIS- based algorithms are used to calculate water flows and the depth-to-water index classes dry, fresh, moist and wet. The purpose of this study was to investigate the possibility to use depth- to-water maps for site adapted planting.The results showed that use of depth-to-water maps for site adapted planting, roughly halved the proportion of improperly planted surfaces from an average of 9 % to 4 %. The variation in the values of proper surface decreased and the result became more even.. In addition, more pine than spruce was incorrectly planted.

With a few liters of clean drinking water : a Cost Benefit Analysis of the socio-economic effects from implementing new clean drinking water technologies in rural India
In 2010, Airwatergreen AB started testing their new technology, the Airwaterwell, an atmospherical water generator of their own design that is running on solar heat, with a production capacity of three litres of water per day and m2. The purpose was to focus on foreign aid organizations as main purchasers for project investments towards rural communities in developing countries that suffer from lack of, or compromised quality of drinking water. In order to further understand if this technology would bring a positive impact in the developing countries, the company contacted the Swedish University of Agriculture for a socio-economic study of the Airwaterwells? potential.
The authors elected Cost benefit analysis as the appropriate method for conducting the study and India became the study region because of its many problems with water related issues such as diseases as well as insufficient water supply for households. The regions that this study is based on are Gujarat, Haryana and Uttar Pradesh given their differences in income, health situation and poverty rate.
Energieffektivisering av färskvattensystemet på Skärblacka pappersbruk
The purpose of this master thesis was to study the water system for mechanically cleaned water at Skärblacka mill, in order to find and evaluate possibilities of using energy more efficiently. The thesis also includes an evaluation of the software tool ?Pumpanalys?Skärblacka mill produces pulp and paper. The large amount of water required is cleaned mechanically through filters and called mechanically cleaned water (MR0). The MR0 water is pumped out to the factory by four crude water pumps.
