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.

Effekter av urbanisering på grönalgen trädgröna i Linköpings stad med omnejd. : Biologiundervisning i närmiljön

Urbanization has for a long time been a threat to our biodiversity. Epiphytic organisms such as lichens have been negative affected by traffic pollution and the new urban environment surrounding their old habitat (van Her 2001). Another epiphytic organism is the green algae Desmococcus olivaceus. Unlike lichens the green algae is favoured by polluted areas. The aim of this study was to investigate if time in urban environments affected the cover of the green algae on old oaks.

Att utkräva ansvar - en analys av Vattenfalls verksamhet i Tyskland

With the expansion onto the international market almost a decade ago, Swedish energy corporation Vattenfall began it's breaking and burning of coal on German soil. Criticism aimed at Vattenfall peaked in the mid 2000s with the revelation of large quantities of carbon dioxide emissions and the re-location of villages and graveyards in German states Brandenburg and Saxony. The purpose of this thesis is to show where the responsibility for these activities lie. By analyzing the history of, and the political debate surrounding, Vattenfall, I will show that the prevailing policies of right- as well as left-wing parties in the 20th century were all, regarding this matter, market oriented. I will also show that these market promoting policies made possible a situation where the transparancy of, and state control over, Vattenfall were close to eliminated.

Miljöekonomiska analyser av smog och luftföroreningsproblemen i Kina

Rapid economic development and urbanization has led to an improved standard of living for the Chinese people. Meanwhile, a series of environmental problems have also appeared and smog, in particular, has caused the Chinese people to realize how serious the situation is. Smog has seriously affected normal economic activities and people's everyday lives, resulting in financial losses, increased mortality and disease. How to handle the smog becomes particularly important. The purpose of this study is to describe and discuss the underlying causes of two sources of pollution, particulate matter and sulfur dioxide, as well as what drives individuals' and firms' environmentally destructive behavior.

This study describes what impact activity within Wifstas, Matfors,Grönstas and Nolbys water protection areas have on the quality of the drinkingwater. It considers the use of the area, environmentally dangerous activitiesin the past and present, the geology?s part, what harm hydroelectric power damsmay cause if they break and how climate change might affect the area in thefuture. It also takes into consideration activities outside the waterprotection areas which might have a suspected impact on the water quality. Theresults of the study are that pollution from infrastructure such as roads, orwastewater from treatment plants may cause occasional contamination of thedrinking water, foremost due to flooding.

Översyn av vattenskyddsföreskrifter med tillhörande vattenskyddsområde i Hallstahammars kommun. : Vilka revideringsbehov finns?

Water is an important food and an important natural resource. In order to protect these are the Environmental Code and the EU directive given to water protection and related water protection regulations will be established for all water sources until 2010. Those who will prepare a water protection and related water protection regulations is the municipality or person responsible for water supply. The person then decides and declares the area as water protection and related water protection regulations are municipal or provincial government. The idea of creating a water protection is to protect the water supply and the body of water against pollution caused by point sources, diffuse sources and accidents combined.

Miljökonsekvensbeskrivning för en utökning av befintlig djurhållning :

In the last few years the environment becomes more watchful, even for us farmers. All agricultural enterprises that exceed 200 animal units must be tested according to regulation of environment. A farm business with 200 animal units and more is classed ?environmentally hazardous activities? and has to make an environmental impact assessment for the business you have today, and the activity after expansion. Before you can construct a building and expand the numbers of animals is a lot of applications to make. I have in this project restricted me to establish a environmental impact assessment and a consultation foundation. To make a environmental impact assessment is the big part of the application. The environmental impact assessment take a lot of time and you need skills for all the rules in the environmental code to be abele to make an environmental impact assessment approved. The environment codes purposes (1 kap 1 § Miljöbalken) is to rule the laws. The purpose of the environment code is to promote sustainable development which will assure a healthy and sound environment for present and future generations. Definitions of a ?environmentally hazardous activities? 9 kap 1§ Miljöbalken) shall mean the discharges of wastewater, solid matter or gas from land, buildings or structures onto land or into water areas or ground water.

Bedömningsgrunder och reningskrav för avloppsreningsverk, 25-2000 pe, i Laholms kommun

The aim of this project was to look into ten small sewer systems in the municipality of Laholm, in Sweden, in order to work out common assessment grounds for them. The sizes of the systems for purification of wastewater were within the range of 25 to 2000 population equivalents. Our method was to study literature, the laws and regulations applicable and the files at the municipality. The conclusion is that every sewer system is different and every situation is unique. We concluded that based on laws and assessment grounds sewer systems equal in size and pollution load ought to have similar demands attached to them.

Brunnsviken : Utvärdering av åtgärder för förbättrad vattenkvalitet

Periods of hypoxia are a recurring issue in Brunnsviken. Main factors that trigger hypoxia in Brunnsviken are eutrophication  due to anthropogenic emission of nutrients, stratification in the water column due to salinity and temperature differences  that prevents mixing and a sill inlet that prevents water exchange. As an attempt to improve the oxygen levels, bottom water is pumped from Brunnsviken causing aerated surface water to flow back into the basin.  The objective of this Master?s thesis was to study the change in dissolved oxygen levels due to pumping.

Städer och planetära gränser : En utvärdering av Stockholms ochNorra Djurgårdsstadens påverkan påde planetära processerna

The concept of planetary boundaries was introduced in the year 2009 by a group ofresearchers led by Johan Rockström and Will Steffen. The group presented a draft of thelimits of the planet regarding nine Earth System processes concerning climate change, oceanacidification, stratospheric ozone depletion, atmospheric aerosol loading, interference with Pand N cycles, global freshwater use, land-system change, rate of biodiversity loss andchemical pollution. The starting point for the study presented in this report was that asustainable development only can be achieved if humankind stays within the boundaries. It istherefore, based on the ongoing urbanization, relevant to evaluate how cities affect the EarthSystem processes. The aim of the study was to investigate if Stockholm Royal Seaport (NorraDjurgårdsstaden), a district in the northeast of Stockholm with a clear environmental profile,affects the Earth System processes less than Stockholm in general does.

Elanslutning av fartyg i hamn : en studie om förutsättningar och konsekvenser för Köpings och Västerås hamn

The purpose of this thesis is to investigate the possibilities for shore side electricity in the ports of Västerås and Köping. A technical solution to connect the vessels to the local grid is suggested and the investigation is also aiming at an understanding of how the environment is affected by the use of shore side electricity. Furthermore, the costs of shore side electricity are considered.The maximum power demand of a vessel visiting the ports today is relatively small, but the ships visiting the ports in the future might have a larger power demand. The suggested dimension for the system is 5 MW and the result shows that the shore side electricity requires the power distribution to the ports to be expanded. The most useful solution in the ports is to connect the ships with 12 kV from a connection box in a pit at the quay.The investigation of the costs shows that it is cheaper for the ships to use electricity compared to the marine fuel.

Dagvatten i Märsta : förslag till anläggning för ekologisk hantering samt metodöversikt

Stormwater in urban areas has been treated as a problem for a long time. The large proportion of impermeable surfaces inhibits the water from infiltrating in the ground to the same extent that it does in nature. This causes intensive surface flow during rain, which in turn causes inconveniences such as decreased accessability, floods and increased risk of desease spreading. Drainage through pipes is the traditional and usually functional metod for storm water disposal. That is as long as water flows are moderate. But precipitation varies naturally in amount and intensity and additional impermeable surfaces make some pipes insufficient for heavy or lasting precipitation.

Krav på exportlicens vid gränsöverskridande transporter av farligt avfall inom EU

The purpose of this essay is to draw attention to the obstacles that affects the internal trade of waste within the EU. The essay doesn?t in any way encourage pollution or illegal handling of waste but unfortunately there are large profits to be made from illegal destruction and recycling of waste and especially hazardous wastes. Therefore the dependable companies handling waste must access a market with fast and flexible (but predictable) regulations as well as lower transaction costs to help make the environment better and encourage a strive for increased recycling. There are examples where some waste only can be sent to a land-fill within the country but could be recycled in other EU-countries.
