  2. 16. Estimation of Forest Biomass and Faraday Rotation using Ultra High Frequency Synthetic Aperture Radar

    Author : Gustaf Sandberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forest Biomass; Ultra High Frequency; Faraday Rotation; Synthetic Aperture Radar;

    Abstract : Synthetic Aperture Radar (SAR) data in the Ultra High Frequency (UHF; 300 MHz – 3 GHz)) band have been shown to be strongly dependent of forest biomass, which is a poorly estimated variable in the global carbon cycle. In this thesis UHF-band SAR data from the fairly flat hemiboreal test site Remningstorp in southern Sweden were analysed. READ MORE

  4. 17. The forgotten forest : on thinning, retention, and biodiversity in the boreal forest

    Author : Julian Klein; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Fennoscandia has had a long history of intensive forest management. It can therefore be regarded a trial zone for other boreal regions which are still largely unaffected by forestry. In Fennoscandia, forestry has resulted in many threatened species and methods that maintain biodiversity have therefore been called for. READ MORE

  5. 18. Forest biomass terminal properties and activities

    Author : Kalvis Kons; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Primary residual forest biomass is an important source of energy in Sweden. The fuel quality of this biomass depends on several factors including its moisture content, ash content, and particle size distribution. READ MORE

  6. 19. Characteristics of Vertical Forest Backscatter Profiles Measured using Radar Tomography

    Author : Patrik Bennet; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forest remote sensing; L-band; above-ground biomass; P-band; vertical reflectivity profiles; radar tomography; temporal backscatter variations;

    Abstract : Forests are an integral part of the Earth’s climate system, having shaped the conditions of life throughout millions of years, but the coverage and conditions of forests are under rapid change. To monitor this change and predict the impact on climate, yearly global mapping of forest Above-Ground Biomass (AGB) is needed. READ MORE

  7. 20. Supporting Management of the Risk of Wind Damage in South Swedish Forestry

    Author : Erika Olofsson; Southern Swedish Forest Research Centre; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; decision support; uncertainty; probability; wind climate; tree growth; forest management; spatial planning; topography; climate change; adaptation; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Private forest owners in southern Sweden consider wind damage to be one of the most problematic risks from an economic perspective. A potential climate change also raises the question of the possible impact of such a climate change on the risk of wind damage. READ MORE
