1. 1. Forest growth under future climate change in the context of bioenergy – case studies of combined heat and power plants in Sweden

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Chi Yuen Hui; [2023]
   Nyckelord :Physical Geography; Climate Change; Ecosystem Modelling; LPJ-GUESS; BECCS; Geomatics; Earth and Environmental Sciences;

   Sammanfattning : The pressure to achieve net-zero emissions has pushed for new technologies including carbon capture and storage (CCS) based on the combustion of biomass (BECCS). While bioenergy is a relatively mature industry in Sweden, the addition of CCS may increase the demand for local biomass. LÄS MER

3. 2. Applying LPJ-GUESS on the Arctic: A model evaluation and benchmarking study

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Margot Jeanne Knapen; [2023]
   Nyckelord :Physical Geography and Ecosystem Analysis; LPJ-GUESS; Arctic; FLUXNET; Gross Primary Productivity; Ecosystem Respiration; Permafrost; Active Layer Thickness; Snow Depth; Earth and Environmental Sciences;

   Sammanfattning : Warming in the Arctic occurs at a much higher rate than the global average, which has a considerable impact on the Arctic terrestrial carbon cycle. Permafrost thawing can release substantial amounts of carbon, whilst tundra shrubification and tree-line advance, on the other hand, may compensate for this. LÄS MER

4. 3. Evaluating a new hydraulic implementation in LPJ-GUESS for three sites in north Europe

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Carl Holmquist; [2023]
   Nyckelord :Physical Geography and Ecosystem analysis; LPJ-GUESS; drought; sensitivity analysis; evapotranspiration; gross primary production; hydraulic parameters; boreal forest.; Earth and Environmental Sciences;

   Sammanfattning : Drought is projected to increase in frequency and intensity and impacts trees with increased water stress and increased mortality rate. Water stresses can cause hydraulic failure-related mortality or carbon starvation due to tree species having different strategies to deal with water stresses. LÄS MER

5. 4. Analysis of simulated functional diversity in tropical forests: Differences between cultivated and naturally grown secondary forests in Cambodia

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Clarissa Graf; [2023]
   Nyckelord :physical geography; ecosystem analysis; functional diversity; plant functional traits; ecosystem modelling; secondary forest ecosystems; sustainable forest management; LPJ-GUESS; Earth and Environmental Sciences;

   Sammanfattning : Accelerated deforestation represents a major global environmental concern. Over the last decades Cambodia has experienced a drastic decrease in forest cover and measures to halt deforestation have not been as effective as planned. LÄS MER

7. 5. Evaluating vegetation carbon storage by primary forests in Sweden using LPJ-GUESS

   Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Sacha van der Vleuten; [2022]
   Nyckelord :Carbon storage; LPJ-GUESS; Primary forests; Sweden; Natural forests; Potential natural vegetation; Dynamic vegetation model; Model optimization; LPJ-GUESS evaluation; Earth and Environmental Sciences;

   Sammanfattning : Over the past 200 years, the structure of forests in Sweden has changed drastically, with forestry becoming the dominant land use. This has led to the loss of primary forests, which has major impacts on different ecosystem services, including carbon storage. LÄS MER
