  1. 1. Impact of different atmospheric forcings on surface mass balance estimates in Greenland

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Stina Olandersson; [2018]
    Nyckelord :Physical Geography and Ecosystem analysis; surface mass balance; Greenland; climate models; numerical weather prediction models; surface energy balance; Arctic; climate change; Earth and Environmental Sciences;

    Sammanfattning : The Greenland Ice sheet (GIS) is the second largest ice sheet on Earth and thus stores a large amount of Earths freshwater. Because of climate change and the Arctic amplification, GIS is experiencing changes and increased melt rates. The total mass budget determines the amount of sea level rise caused by input from freshwater from the GIS. LÄS MER

  2. 2. Hur utvärderas faunapassager? - En litteraturstudie om säkra passager för djur över vägar och hur de utvärderas

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Sara Schrödl; [2018]
    Nyckelord :vägar; habitatfragmentering; barriäreffekt; isolering; viltolyckor; djurpassage; faunapassage; wildlife crossing; utvärdera; användning; förflyttning; beteende; genflöde; genvariation; Population Viability analysis; kamera; spåranalys; telemetri; Passive Integrated Transponder; Earth and Environmental Sciences;

    Sammanfattning : Habitat fragmentation is a common problem in relation with road infrastructure which leads to mortality, isolation of animal populations, and has a negative effect on biodiversity. Animal crossings have been implemented in many countries and are a useful tool to mitigate these problems but they are expensive to build. LÄS MER

  3. 3. Risk mapping of phosphorus leakage - improved method using a Digital Elevation Model

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Hanna Ekström; [2018]
    Nyckelord :surface runoff; erosion; phosphorus leakage; agriculture; sinks; Earth and Environmental Sciences;

    Sammanfattning : Eutrophication is an ongoing problem in the Baltic Sea and is therefore found as a topic of the Baltic Sea Action Plan as well as the environmental goals of Sweden. One source to eutrophication is the leakage of phosphorus from agricultural lands. LÄS MER

  4. 4. Klimatpåverkan från privat och offentlig konsumtion i Kungsbacka kommun

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Julia Nordström; [2018]
    Nyckelord :konsumtionsbaserade utsläpp; offentlig konsumtion; privat konsumtion; beräkningsmodeller; input-output analys; klimatstrategi; kommunalt klimatarbete; Earth and Environmental Sciences;

    Sammanfattning : In recent years, it has become increasingly recognized that the traditional production-based methods for calculations of greenhouse gas emissions have shortcomings. This is justified by the fact that such inventories only include emissions that occur within a particular geographical area. LÄS MER

  5. 5. Waste prevention of ICT products towards circular economy

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Hanna Wadsten; [2018]
    Nyckelord :ICT products; waste; waste prevention systems; circular economy; municipalities; Earth and Environmental Sciences;

    Sammanfattning : Information and Communications Technology (ICT) is something that drives our society forward, but how we are consuming these products is rather something that harm our environment rather than pushing our society forward. This thesis investigates our unstainable consumption of ICT products and takes a look at waste prevention solutions in order to reach circular economy with a focus on Swedish municipalities. LÄS MER
