1. 1. Att skapa resiliens med hjälp av kolinlagring och biodiversitet : en fallstudie med beräkning av kolförråd och kolbalans i Tierps kommun

   Kandidat-uppsats, Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

   Författare :Elisabeth Bäckman; Ronja Sundström; [2023]
   Nyckelord :carbon sink; carbon source; biodiversity; climate change; kolsänka; kolkälla; biologisk mångfald; klimatförändringar;

   Sammanfattning : Markanvändningssektorn (LULUCF) står för 7–11 % av de globala utsläppen av växthusgaser, däribland koldioxid (CO2), metan (CH4) och dikväveoxid (N2O). Genom förändringar av markanvändningen kan kolinlagringen i mark och vegetation ökas och sektorn kan istället vara med och bromsa klimatförändringarna. LÄS MER

3. 2. Reindeer decrease soil carbon stocks and deplete labile soil carbon

   Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Josua Seitz; [2022]
   Nyckelord :Reindeer; SOC; soils; Finnland; 13C NMR;

   Sammanfattning : Reindeer have been shown to alter boreal ecosystems by changing the vegetation cover and influencing belowground processes. By providing nutrients for plants and by exerting trampling stress on the field layer vegetation, reindeer induce shifts in the vegetation where ground-lichen are being replaced by evergreen shrubs.

4. 3. Forest structure of Dalby Söderskog National Park : patterns of carbon storage in living and dead trees

   Master-uppsats, SLU/Southern Swedish Forest Research Centre

   Författare :Kumetra Achuthan; [2021]
   Nyckelord :ash dieback disease; deadwood; Dutch elm disease; living tree volume; coarse woody debris; carbon stock and storage; pest invasions; temperate mixed broadleaved forest;

   Sammanfattning : Carbon sequestration and storage is an ecosystem service supplied by forests, and is of increasing importance in the context of mitigation of global climate change. Forest pest invasions, driven primarily by globalizations, represent a risk to the efficiency of carbon sequestration as they may greatly reduce the amount of the living biomass in forests. LÄS MER

5. 4. Carbon budgets in northern Swedish Forests, 1800-2013

   Master-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :Gustav Stål; [2018]
   Nyckelord :climate change mitigation; northern Swedish forests; carbon dept; substitution; harvested wood products; klimatförändringar; norra Sveriges skogar; kolskuld; substitution; träprodukter;

   Sammanfattning : Forests and forest management can mitigate increased carbon dioxide (CO2) concentrations in the atmosphere through sequestration of carbon and/or substitution. A major question has been whether it is better to use or conserve forests, with some claiming that European forests carry a huge carbon debt as a result of forestry. LÄS MER

7. 5. Biophysical changes following landscape restoration : in Changting model restoration site in Fujian province, southern China

   Master-uppsats, SLU/Southern Swedish Forest Research Centre

   Författare :Martin Ewertson; [2016]
   Nyckelord :afforestation; biomass carbon pools; carbon and nitrogen in soil; broadleaves enrichment; eroded red soil;

   Sammanfattning : China has promised to tackle climate change by decreasing its emission and promote carbon sinks primarily by forest plantations and restorations. There is a growing debate about the impacts of large-scale restorations using few fast-growing species on the kind of ecosystem we are creating and its adaptation to the future environmental conditions.
