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

   University essay from SLU/Southern Swedish Forest Research Centre

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

   Abstract : 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.

3. 2. Modelling vegetation dynamics and carbon fluxes in a high Arctic mire

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Laura Reinelt; [2015]
   Keywords : methane dynamics; biogeochemical cycling; vegetation dynamics; ecosystem modelling; LPJ-GUESS; geography; physical geography; high Arctic wetland; Zackenberg; Earth and Environmental Sciences;

   Abstract : High Arctic wetlands are an important component of the global climate system. Nevertheless estimations of their expected response to climate change and associated climate-feedbacks have large uncertainties. Improving models for vegetation and carbon dynamics of ecosystems is an important step towards making predictions more accurate. READ MORE

4. 3. Modeling the effect of activelayer deepening on stocks ofsoil organic carbon in thePechora River Basin

   University essay from Institutionen för naturgeografi och kvartärgeologi (INK)

   Author : Pia Eriksson; [2012]
   Keywords : permafrost; global warming; carbon cycling; GIS;

   Abstract : This study investigates how the estimated thickening of the active layer will affectthe soil organic carbon in permafrost soils. The focus lies on estimating how muchof the upper permafrost soil organic carbon will be affected by the active layerdeepening due to global warming, on what timescale the deepening will take placeand if the estimated changes differ depending on the extent of permafrost in theregion.

5. 4. Modelling soil temperature & soil water availability in semi-arid Sudan : validation and testing

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Lina Möllerström; [2004]
   Keywords : geomorfologi; naturgeografi; climatology; carbon sequestration; Sahel; physical geography; water content; geomorphology; cartography; pedology; marklära; kartografi; klimatologi; Earth and Environmental Sciences;

   Abstract : The aim with this thesis was to investigate the land surface model used in DAYCENT. Through comparing the simulated soil moisture and soil temperature results with observed data, at the depth of 30 and 60 cm at the Demokeya site in semiarid Sudan, it was possible to evaluate the model.
