1. 1. Where have all the forests gone? Quantifying pantropical deforestation drivers

   Författare :Florence Pendrill; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Carbon footprints; International trade; Deforestation; Consumption-based accounting; Forest transitions; Telecoupling; Agriculture; Land use change; Carbon emissions; Land system science;

   Sammanfattning : Deforestation across the tropics continues to be a major source of greenhouse gas emissions and the largest threat to biodiversity on land. With strengthened commitments to reduce deforestation from countries and companies alike, it is crucial that renewed investments for reducing deforestation be guided by a sound understanding of what drives deforestation.

3. 2. Words Matter in the Woods : Discourses on Deforestation in Global Climate Politics

   Författare :Tobias Nielsen; Statsvetenskapliga institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Global climate politics; deforestation; REDD ; UNFCCC; argumentative discourse analysis;

   Sammanfattning : Over the past decade, avoiding deforestation has become a central element of the UN Framework Convention on Climate Change (UNFCCC). The focal point of this has been the incentive-based mechanism of REDD+, which stands for Reducing Emissions from Deforestation and forest Degradation. LÄS MER

4. 3. 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

5. 4. Remote Sensing of Forest Decline in the Czech Republic

   Författare :Jonas Ardö; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Czech Republic; neural networks; sulphur dioxide; air pollution; Norway spruce; deforestation; forest decline; GIS; spectral characteristics; Remote sensing; Landsat; Ore Mountains; Geology; physical geography; Geologi; fysisk geografi;

   Sammanfattning : This thesis describes the localisation and quantification of deforestation and forest damage in Norway spruce forests in northern Czech Republic using Landsat data. Severe defoliation increases the spectral reflectance in all wavelength bands, especially in the mid infrared region. LÄS MER

7. 5. 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
