Aerosolers dygnsvariationer och långväga transporter

This work aims to obtain information on diurnal variations of aerosol concentrations in thecity of Lund (Sweden) and trying to locate the origin of the aerosols long distance transports.The study shows that the aerosol concentrations varied quit strongly over the entiremeasurement period, reflecting air masses of different degrees of pollution, mainly as a resultof the diurnal rhythm of the traffics. Trajectories reveals that air masses originated inSoutheastern and Eastern Europe contains higher aerosol concentrations compared to other airmasses..

En studie av landskapsindex för kvantifiering av rumsliga landskapsmönster

Syftet med uppsatsen är att utvärdera två landskapsindex: ett formindex som beräknar formen för varje markanvändningsyta ( eng. "patch"); ett diversitetsindex, som beskriver de olika markanvändningarnas relativa utbredning. Formindexet beräknas på två olika sätt, beroende på om dess storleksberoende inkluderas eller ej. Utvärderingen körs för ett landskap på cirka 50 km2, men även för tre mindre områden i landskapet: åkerbygd, mellanbygd samt skogs-bygd. Samtliga områden jämförs sedan i två olika skalor, flygbild respektive satellitbild..

Sårbarhetskartering av bekämpningsmedelsläckage till grundvattnet : tillämpat på vattenskyddsområdet Ignaberga-Hässleholm

Målsättningen med detta arbete är att ta fram en metod för att kartera och analysera den rumsliga variationen av landskapets sårbarhet för miljögifter, samt att visa hur geografiska informationssystem (GIS) kan underlätta denna rumsliga kartering och analys. Analysen utfördes inom vattenskyddsområdet Ignaberga-Hässleholm i Hässleholms kommun. Först studerades sårbarheten utifrån markens förutsättningar med hjälp av modellen DRASTIC och sedan studerades var de mest mobila bekämpningsmedlen har använts i förhållande till resultaten från DRASTIC..

WHITE HOUSE/GREEN HOUSE - En processpårande undersökning av klimatfrågan i USA

This thesis examines the process of securitization of the environmental issue in the United States. By using the theories of sectoral security and securitization by Barry Buzan and Ole Waever, commonly known as the Copenhagen school we go beyond the traditional security frames and examine where the environmental issue in the United States stand today within the securitization spectrum. The securitizing spectrum includes three levels in which an issue can be place: non-politicised, politicised and securitized.The problem, which we wish to address, is if there is a movement of the environmental issue in the United States towards becoming a securitized issue. In the light of these circumstances we also wish to explore who is behind the movement and also find out where the issue stand today. We do believe that Al Gore is a securitizing actor and examine his role in the movement of the environmental issueWe have come to the conclusion that there is an ongoing process of securitization in which the environmental issue have moved from being politicised to becoming securitized..

Markvattenhalt och temperatur i sandig jordbruksmark vid Ilstorp, centrala Skåne : en mätnings- och modelleringsstudie

Vinderosion på jordbruksmark har länge varit ett välkänt faktum trots att någon utförligare undersökning om dess omfattning och skadeverkan inte tidigare genomförts. Mot bakgrund av detta har därför ett nordeuropeiskt projekt, WEELS (Wind Erosion on European Light Soils), dragits i gång som syftar till kartlägga vinderosionen på sandig jordbruksmark i norra Europa och som man i slutändan hoppas ska kunna resultera i en vinderosionsmodell. Detta har genomförts med SOIL modellen, en matematiskt fysikaliskt baserad modell för simulering av vatten och värmeflöde i en skiktad jordmånsprofil..

Naturen som TV-underhållning: En ideologikritisk studie av BBC:s "Planet Earth"

Den här uppsatsen behandlar TV-serien Planet Earth ur ett ideologikritiskt perspektiv. I uppsatsen utgår jag från att även en naturdokumentär som Planet Earth är en subjektiv text vilken präglas av kulturella värderingar och ideologiska intressen. Jag granskar hur man valt att presentera naturen och djurlivet, i syfte att klarlägga de värderingar som serien speglar. Planet Earth följer vissa konventioner som finns för denna typ av produktion. Man använder sig av en berättande struktur som innebär fokus på individuella karaktärer, tydliga händelseförlopp och en applicering av gott och ont på djuren.

Miljöhänsyn inom EU:s sektorspolitik - integrering genom "nya" policyinstrument?

To integrate environmental concerns into non-environmental policy making has become an important policy objective within the European Union. This essay investigates policy instruments in use to achieve environmental policy integration in the EU's transport sector respectively fisheries sector. The point of departure is a theoretical discussion about governance and the use of different policy instruments for environmental management at the EU-level. The focal point is the argumentation that regulatory policy instruments alone cannot achieve environmental policy integration satisfactory. By using Jordan et al's classification of so called "new" environmental policy instruments (market-based instruments, voluntary agreements and ecolabels) as complements to regulatory measures, the essay investigates whether the first-mentioned are used within the two sectors.

Webbsida med WEB 2.0

The consumer society exploits the earth?s resources more than the earth itself has capability to produce. This over-consumption causes a mass production of products, which mean that more greenhouse gases are being emitted to the atmosphere. This is one of the reasons why the earth?s temperature is rising, where the result of it is worldwide disasters.

Ny konsumtion av gamla kläder : ? En studie om konsumenters miljömedvetenhet och motiv till att köpa second hand kläder på Myrorna

The world?s consumption is increasing at an accelerating rate and it´s produced and consumed more goods and services than ever before. A large part of people's consumption consists of clothing that is bought and discarded increasingly leading to a number of environmental problems such as global warming, pollution, loss of biodiversity and the depletion of natural assets. One way to save the earth's resources is to buy used clothing, so called second hand, instead of new ones. The store chain ?The Ants? (in Swedish ?Myrorna?) has specializing in second-hand goods and sells, among other things, clothes.

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.

Miljöpolicyintegration hos Sida? - nedslag i ett policyurval för att identifiera EPI

The development aid from Sweden to developing countries is a activity thatinvolves a great deal of monetary founds as well as an opportunity to influence the environmental situation in a partner country. It´s also an opportunity to promote Sweden's values in a field like the environment, setting a good example is important. This thesis aims to evaluate Sida´s environmental policy and find out if there in fact is a Environmental Policy Integration Policy (EPI) taking place. EPI is a policyimplementation theory that emphasise the importance of the total integration of the environmental in the organisation as a whole. To identify this I will use a theoretical framework of indicators invented by William M.

Revision av miljöledningssystemen i statliga myndigheter : Utvärdering av ett verktyg i det systematiska miljöarbetet

The Swedish government decided in 1996 that the governmental authorities are to implemementenvironmental management systems. Each year, the Swedish Environmental ProtectionAgency compiles the authorities? reports on their environmental management systems. Thecompilation shows that not more than 20 % of the authorities perform environmental audits.This study aims to investigate the authorities? view of internal environmental audits, the incentivesof performing them.

Från Rio via Kyoto, till Marrakech. Hur har rättviseproblematiken tolkats i anpassningsdiskussionerna?

Global climate change is one of the greatest challenges in our history. As the average temperature is rising due to anthropogenic emissions, impacts such as floods, droughts and hurricanes, affect the lives of millions of people. Though the least developed countries are least responsible for emissions, they are the worst affected. This thesis focuses on environmental justice in the adaptation discourse. By outlining the adaptation discourse from the United Framework Convention on Climate Change principles, to the Marrakesh Accords, via the Kyotoprotocol my ambition is to analyse how environmental justice has been interpreted in relation to the adaptation discourse.

Grön olja? - En fallstudie av ett oljebolags miljöprofilering

While the call for regulations against greenhouse gas emissions are louder then ever before, demand for oil is also at an all time high. Oil companies face the dilemma of making sound business without being perceived as environmental villains. In this essay I will examine how BP, one of the largest companies in the world, broke rank with the industry and devoted itself to being an environmental friendly oil company. The actions and motives of this change will be evaluated through up-to-date theories about company motivation to environmental adaptation. We see that BP:s transformation can be well explained through Simone Pulvers theory about the socially embedded company.

Development and evaluation of environmental enrichment for captive Humboldt penguins

Environmental enrichment is of high importance for zoos. Borås zoo asked SLU (Swedish University of Agricultural Sciences) for a student to perform a bachelor thesis for them. The task was to develop and evaluate environmental enrichment for their Humboldt penguins. A structure was made, consisting of a sinking skeleton with a floating bridge attached to it. It was presented in an area of the pool that the keepers had experienced that the penguins did not use to any extent.
