1. 16. Exploring patterns in risk factors for bark beetle attack during outbreaks triggered by drought stress with harvester data on attacked trees: A case study in Southeastern Sweden

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Nikolaos Kouskoulis; [2023]
   Keywords : Geography; GIS; Geographic Information Science; Forest ecosystems; Bark beetle outbreak; Southeastern Sweden; Predisposing factors; Triggering factors; Drought stress; Earth and Environmental Sciences;

   Abstract : ABSTRACT Raising temperatures and climate variability have intensified extreme weather events worldwide. These extremes can enhance and trigger possible pest outbreaks. Bark beetle attacks have become a major concern in regions with extensive spruce forest areas. Southeastern Sweden has faced repeated outbreaks resulting in widespread tree loss. READ MORE

3. 17. The impact of CO2 fertilisation on foliage in West and East Africa

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Gaetane Demyttenaere; [2023]
   Keywords : Physical geography and ecosystem analysis; CO2 fertilisation; semi-arid ecosystems; remote sensing; Normalised Difference Vegetation Index; Earth and Environmental Sciences;

   Abstract : Anthropogenic impact on terrestrial ecosystems continues to grow as we further enhance atmospheric Carbon Dioxide (CO₂) concentrations. The changing climatic conditions and direct influence of CO₂ on vegetation has a big impact on ecosystem functions. READ MORE

4. 18. Can ancient pathogens emerging from glaciers and permafrost reach Europe by aerosolization?

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Anna Bruhn; [2023]
   Keywords : Ancient pathogens; Greenland; Aerosolized pathogens; Aerosol transport; Earth and Environmental Sciences;

   Abstract : Glaciers and permafrost capture bacteria and viruses when they form, which can be suspended for millennia. This includes long since extinct pathogens which are functionally novel. As polar regions get warmer these pathogens will emerge and spread through the local ecosystem, potentially altering it. READ MORE

5. 19. Impact of wetland restoration on river discharge - A case study of Bråån, Skåne, Sweden

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Ardis Luda; [2023]
   Keywords : wetlands; wetland restoration; HYPE model; river discharge; Sweden; land use change; flooding; hydrological modeling; Earth and Environmental Sciences;

   Abstract : Land use change is a factor not often considered when modeling river discharge in regard to future flood risk. The restoration of wetlands is an ongoing land use change which affects water storage capacity in the soils of a catchment and could lead to lower flows in rivers. READ MORE

6. 20. Thinking Outside of the Organisational Box; How Private Firms Can Invest in Nature-based Solutions at the Watershed-level to Manage Agricultural Water Risks in California’s San Joaquin Valley

   University essay from Lunds universitet/Internationella miljöinstitutet

   Author : Ethan Dunnenberger; [2023]
   Keywords : water scarcity; agriculture; private sector; risk management; nature-based solutions; watershed restoration; San Joaquin Valley; water security; value; Earth and Environmental Sciences;

   Abstract : Nature-based solutions (NBS) can provide a range of benefits to tackle acute sustainability challenges in an enduring and cost-effective manner. Increasing recognition of the value of these solutions has led to their adoption across the globe. READ MORE
