1. 16. 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

3. 17. Automatic icon placement approach for improved association & walkability on city wayfinding maps

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Sofia Apostolidou; [2023]
   Keywords : Physical Geography; Ecosystem Analysis; Cartography; Icon placement; High density; City wayfinding maps; Quality metrics; Association; Disturbance; Legibility; Cartographic guidelines; Grid algorithm; Evaluation; Multi-objective optimization; NSGA-II; Pareto front; Walkability; Geomatics; Earth and Environmental Sciences;

   Abstract : With the evolution of cartography from hand-drawn to digital maps, the task of icon placement has become increasingly complex. Nowadays there is a need to automate this process to produce high quality results in less time. READ MORE

4. 18. 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. 19. Testing aerosol vertical profiling methods with portable instruments on unmanned and manned aircraft

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Ellen Grace Soroka; [2023]
   Keywords : Physical Geography; Ecosystem Analysis; Aerosols; Vertical Profile; Black Carbon; PM2.5; Nanoparticles; UAV; Drone; Master degree thesis; 30 credits in Atmospheric Science Biogeochemical Cycles; Earth and Environmental Sciences;

   Abstract : This thesis employed several portable sensors on board an unmanned aerial vehicle (UAV) and manned aircraft in order to test new methods of measuring vertical profiles of aerosol particles and contribute to knowledge of aerosol distributions in the atmosphere. More data in this area is required to improve atmospheric modelling and future climate scenarios. READ MORE

6. 20. Urban tree canopy mapping -an open source deep learning approach

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Tobias Rydlinge; [2023]
   Keywords : Geography; GIS; AI; deep learning; urban trees; remote sensing; Earth and Environmental Sciences;

   Abstract : Urban trees have an important role to provide ecosystem services and to make our cities greener and more sustainable. The changing climate and densification of cities make it even more valuable to preserve and investigate in urban trees. READ MORE
