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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Abstract : 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. READ MORE

  6. 5. Evaluation of the LPJ-GUESS crop model under ambient and elevated CO2 concentrations.

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Annika Nitschke; [2022]
    Keywords : LPJ-GUESS; free-air carbon dioxide enrichment experiments; elevated CO2; climate change; wheat yield; Earth and Environmental Sciences;

    Abstract : In the future atmospheric CO2 concentrations might exceed 550 ppm according to the RCP8.5 scenario by mid-century from our current 410 ppm, while our world population is projected to surpass the 9.7 billion threshold within the same time span. This challenge leads to the raising of questions addressing future food security. READ MORE
