21. The Impacts of Mining on Arctic Environment and Society from Corporate Social Responsibility and Sustainable Development Perspectives : The Case of Jokkmokk (Kallak) Iron Mines in Northern Sweden
University essay from Stockholms universitet/Institutionen för naturgeografiAbstract : Extractive industry in Arctic is controversial due to the ecosystems and communities in the region are highly sensitive to natural and anthropogenic disturbances as it is one of the world’s global change hot-spots, as well as its uniqueness and distinctive social and ecological significance. As mining industry has developed into sophisticated operations, yet the basic causes of environmental pollution and degradation and impacts on the natural environment of the Arctic region remain unchanged.

22. Climate change effects on freezing damage in three subarctic bryophytes : A snow manipulation field experiment in a tundra ecosystem in Abisko, Sweden
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Climate change is expected to have a large impact on northern ecosystems. Increased temperatures and altered precipitation and snow cover patterns will have a great impact on subarctic tundra. Bryophytes form an important component of tundra ecosystems because of their high abundance and their importance in many ecological processes. READ MORE

23. Trends in high peak flow generation across the Swedish Subarctic
University essay from Stockholms universitet/Institutionen för naturgeografiAbstract : There is growing concern for increased frequency of extreme events due to several severe floods and droughts occurring globally in recent years. Improving knowledge on the complexity of hydrological systems and interactions with climate is essential to be able to determine drivers and predict changes in the future. READ MORE

24. Object-Based Classification of Vegetation at Stordalen Mire near Abisko by using High-Resolution Aerial Imagery
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The focus of this work is to investigate and apply the remote sensing method of object-based image analysis (OBIA) for vegetation classification of a permafrost underlain peatland in sub-arctic Sweden, by using aerial imagery of high resolution. Since the northern landscapes are an important source of naturally stored CH4 and CO2, their contribution to the global carbon cycle is a focus in research about climate change and the global methane exchange.

25. The suitability of using Landsat TM-5 Images for estimating chromophoric dissolved organic matter in subarctic Lakes
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Recent trends of permafrost thawing in the subarctic are expected to cause increased release of dissolved organic carbon (DOC) to inland waters, which might have cascading effects on downstream aquatic ecosystems and release of CO2 to the atmosphere. This study therefore aimed at evaluating the applicability of an empirical band ratio algorithm for estimating chromophoric dissolved organic matter (CDOM; a proxy for DOC) from the easily accessible satellite images Landsat TM-5, to counter the inaccessibility of the region in general.
