1. 1. Natural and social dimensions of forest carbon accounting

   Författare :Wilhelm Dubber; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Forest carbon fluxes; REDD ; boreal forest; LPJ-GUESS; BIOME-BGC; remote sensing;

   Sammanfattning : Global forests store large amounts of carbon both in living biomass and in the soil. The ability of forests to counteract climate change by acting as carbon sinks have been recognized in global climate politics, such as the 2015 Paris agreement which calls for national commitments to reduce greenhouse gas emissions.

3. 2. Carbon gas biogeochemistry of a northern peatland - in a dynamic permafrost landscape

   Författare :Kristina Bäckstrand; Patrick M. Crill; Torben R. Christensen; David Bastviken; Kimberly P. Wickland; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbon balance; Carbon exchange; Peatland; Subarctic; Climate change; Earth sciences; Geovetenskap; geokemi; Geochemistry;

   Sammanfattning : This thesis is about biogeochemical processes of a northern peatland and their importance as a link between the climate and the terrestrial system. Increased temperatures on a global level, and particularly in the Arctic, have led to melting permafrost and changes in hydrology. LÄS MER

4. 3. 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.

5. 4. To leak or not to leak? : Land‐Use Displacement and Carbon Leakage from Forest Conservation

   Författare :Sabine Henders; Madelene Ostwald; Martin Persson; Julie Wilk; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; land‐use change and deforestation; accounting methods; consumer and producer responsibility; REDD ; Klimatförändring; markanvändning och avskogning; redovisningsmetoder; konsument‐ och producentansvaret; REDD ;

   Sammanfattning : This thesis investigates the question how emissions from land‐use displacement can be assessed and accounted for, using the example of carbon‐leakage accounting in the planned UNFCCC mechanism on ‘Reducing Emissions from Deforestation and Forest Degradation’ (REDD). REDD serves here as example of an international forest conservation policy that might be effective locally but could lead to displacement of deforestation to other countries. LÄS MER

7. 5. Carbon Nitride and Carbon Fluoride Thin Films Prepared by HiPIMS

   Författare :Susann Schmidt; Lars Hultman; Grzegorz Greczynski; Charanjit Singh Bhatia; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : The present thesis focuses on carbon based thin films prepared by high power impulse magnetron sputtering (HiPIMS) and direct current magnetron sputtering (DCMS). Carbon nitride (CNx: 0 < x < 0.20) as well as carbon fluoride (CFx: 0.16 < x < 0. LÄS MER
