  1. 1. The Effects of Clear-Cutting a Hemiboreal Forest on Local CO2 Fluxes in Norunda, Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Mads Carlsen; [2023]
    Keywords : CO2 flux; Clear-cutting; Coniferous forest; Flux footprint; Sustainable forestry; Earth and Environmental Sciences;

    Abstract : As CO2 builds up in the atmosphere causing global climate change (IPCC, 2022) trees have become an international symbol of combatting this, and for good reason. Trees take up CO2 which as a result combats these changes, and when these trees are cut down fewer individuals remain to take up the CO2 that we humans emit (Chapin et al., 2011). READ MORE

  3. 2. Towards climate optimised riparian buffer zones in boreal forests

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Alice Falk; [2022]
    Keywords : Forestry; Biogeochemical hotspots; Carbon dioxide; Methane;

    Abstract : Boreal forests have the potential to mitigate the increased concentrations of greenhouse gases (GHGs) in the atmosphere. However, forestry alters the soil biogeochemical processes which can cause an increase in GHG emissions from nearby water bodies, soil and vegetation. READ MORE

  4. 3. Influence of permafrost disintegration on wetland carbon fluxes in Abisko, Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Aida Esmailzadeh Davani; [2021]
    Keywords : Physical Geography; Ecosystem Analysis; Permafrost; CH4 flux; CO2 flux; Abisko; Wetlands; Earth and Environmental Sciences;

    Abstract : The northern permafrost regions are experiencing a rapid warming as surface temperatures are rising, causing a disintegration of permafrost and a deepening of the active layer (AL). This releases previously frozen carbon, making it available for decomposition by microbes. READ MORE

  5. 4. Assessment of how environmental variables and vegetation structure influence peatland carbon fluxes

    University essay from Uppsala universitet/Växtekologi och evolution; Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Bernabé Ramírez; [2021]
    Keywords : ;

    Abstract : Boreal peatlands are important ecosystems from a carbon balance perspective because they are natural carbon sinks as a result of millennia of peat formation. However, due to climate change, these ecosystems are susceptible to changes in hydrology and temperature. READ MORE

  6. 5. Spatial variation in GHG emissions from drained organic forest soils : implications for Swedish UNFCCC reporting

    University essay from SLU/Dept. of Soil and Environment

    Author : Anna Oskar; [2021]
    Keywords : greenhouse gas; carbon dioxide; methane; nitrous oxide; peat; drainage; ditch; GHG inventory;

    Abstract : Drainage of organic soils for forestry generally increases soil CO2 and N2O emissions but decreases CH4 emissions. Under the United Nations Framework Convention on Climate Change (UNFCCC) countries provide annual national inventories of anthropogenic greenhouse gas (GHG) emissions and removals, which includes emissions of GHGs from drained organic forest soil.
