  1. 1. Characteristics of Vertical Forest Backscatter Profiles Measured using Radar Tomography

    Författare :Patrik Bennet; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  2. 2. Forest and land use mitigation and adaptation in Sri Lanka – Aspects in the light of international climate change policies

    Författare :Eskil Mattsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; land use; Sri Lanka; REDD ; CDM; deforestation; biomass; carbon stock; forest; carbon stock; biomass; forest; land use; deforestation; Sri Lanka; REDD ; CDM;

    Sammanfattning : As a developing island nation, Sri Lanka is vulnerable to the possible impacts of climate change. The land use and forestry sector accounts for a large part of Sri Lanka’s greenhouse gas emissions and can play a major part of Sri Lanka’s strategy to mitigate and adapt to climate change. LÄS MER

  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; []

    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. Mechanisms of below-ground carbon cycling in subarctic ecosystems

    Författare :Maria Olsrud; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; pedology; geomorphology; Physical geography; subarctic tundra; phosphorous mobilization; organic acids; open top chamber experiment; 15N natural abundance; Ericoid mycorrhizas; global change; 14C pulse-labelling; Carbon allocation;

    Sammanfattning : Some components of the below-ground carbon (C) cycle in terrestrial ecosystems are still poorly understood. A better understanding will be necessary to predict adequately the impacts of global change factors on C cycling and storage, especially in high-latitude ecosystems, where much of the C is stored below-ground.

  5. 5. Potentials and wood fuel quality of logging residues from indigenous and planted forests in Mozambique

    Författare :Rosta Mate; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Search for complementary and alternative renewable energy sources is imperative to meet the current growing demand for wood fuel and for diversification of electricity supply sources in Mozambique. Logging residues from timber harvesting operations and whole tree biomass from short rotation coppice (SRC) are available options. LÄS MER
