  1. 1. Carbon Balance Implications of Forest Biomass Production Potential

    Författare :Bishnu Chandra Poudel; Inga Carlman; Johan Bergh; Thomas Lundmark; Roger Sathre; Mittuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; forest management; silviculture; clear-cut forestry; continuous-cover forestry; substitution; total carbon; climate benefit; climate change; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Forests in boreal and temperate forest-ecosystems have importance for carbonbalance since they sequester large amount of atmospheric carbon by uptake ofcarbon-dioxide during photosynthesis, and transfer and store carbon in the forestecosystem. Forest material can be used for bio-fuel purposes and substitute fossilfuels, and supply wood products, which can replace carbon-and-energy-intensivematerials. LÄS MER

  2. 2. Direct and indirect pressures of climate change on nutrient and carbon cycling in northern forest ecosystems : Dynamic modelling for policy support

    Författare :Klas Lucander; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Forest; boreal ecosystems; Forest biogeochemistry; Forest bioenergy; Boreal coniferous forest; base cations; Biogeochemical cycles; Dynamic Modelling; Carbon cycle; nitrogen cycle; decision support; policy-making; Weathering; Forestry; Land use change;

    Sammanfattning : Northern forest ecosystems play an important role in mitigating climate change by sequestrating carbon (C), while additionally providing and regulating other ecosystem services. A majority of the Swedish environmental quality objects (EQOs) that guide Swedish environmental policy and management are associated with the forest, and they have proven difficult to achieve.

  3. 3. Greenhouse Gas Fluxes and Carbon Sequestration in Young Norway Spruce Stands : The Effects of Fertilization

    Författare :Charlotta Håkansson; Johan Bergh; Per-Ola Hedwall; Monika Strömgren; Anna M. Jensen; Tomas Lundmark; Tobias Rütting; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; carbon balance; young mixed forests; Picea abies L. Karst. ; Betula spp; chamber measurements; forest floor greenhouse gas fluxes; eddy-flux technology; above ground biomass; carbon dioxide; methane; nitrous oxide; kolbalans; ung blandskog; Picea abies L. Karst. ; Betula spp; kammarmätningar; markflöden av växthusgaser; eddy-fluxteknik; biomassa ovan jord; koldioxid; metan; lustgas; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : The enormous challenge of climate change is discussed and debated today because of its major impact on life on Earth. The forests have an important role to play as the plants absorb carbon dioxide (CO2) from the atmosphere through their photosynthesis and the growing tree retain carbon (C). LÄS MER

  4. 4. Timber as a forest-risk commodity: embodied socio-ecological impacts in the Brazilian supply chain

    Författare :Caroline Sartorato Silva Franca; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Environmentally-extended input-output model; Land use; Supply chain traceability; Forest frontiers; Sustainable Forest Management SFM ; Forest degradation; Illegal logging;

    Sammanfattning : The continued loss and degradation of forest resources is one of the largest sustainability challenges of our time. The past decades rise in global demand for agricultural and forest commodities have created unparalleled pressure on the natural resources, leading to forest destruction and associated loss in carbon stocks, invaluable biodiversity, ecosystems services, livelihoods.

  5. 5. Felling Forests from Afar: Quantifying Deforestation Driven by Agricultural Expansion and International Trade

    Författare :Florence Pendrill; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Forest transitions; Land cover; Carbon footprints; Agriculture; Forestry; Carbon emissions; Land use; International trade; Deforestation;

    Sammanfattning : Deforestation is a major source of human-caused greenhouse gas emissions and the largest threat to terrestrial biodiversity. Most forest loss is due to the expansion of agricultural land use increasingly driven by international demand for food, fuel and fibre. LÄS MER
