1. 11. Can ancient pathogens emerging from glaciers and permafrost reach Europe by aerosolization?

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

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

   Sammanfattning : 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. LÄS MER

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

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

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

   Sammanfattning : 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. LÄS MER

4. 13. Evaluation of the ERA5-Land dataset for estimation of soil moisture in the permafrost region

   Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

   Författare :Alberta van Gent; [2023]
   Nyckelord :Soil moisture; ERA5-Land; International Soil Moisture Network ISMN ; permafrost region;

   Sammanfattning : The permafrost region covers a vast area of land surface on the northern hemisphere,storing large amounts of carbon. Unfortunately, climate warming leads to permafrostthaw altering the hydrothermal state of permafrost soils. Due to the remoteness of thepermafrost region, access to field measurements is restricted.

5. 14. Towards a Geographic Information Systems and Data-Driven Integration Management.

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

   Författare :Takura Matswetu; [2023]
   Nyckelord :Migrant Integration; Geography; Physical Geography; GIS; Network Analysis; Tampere; Accessibility; Data-driven decision making; Holistic Integration Index; Mathematics and Statistics; Social Sciences; Earth and Environmental Sciences;

   Sammanfattning : Integration management in Finland and Tampere is broad task including multiple actors and departments. To manage integration, is to coordinate the cross organizational cooperation of multiple service structures that support migrants with different kinds of services. LÄS MER

7. 15. Ecological risk assessment of pesticide use in rice farming in the Mekong Delta , Vietnam

   Magister-uppsats, Stockholms universitet/Institutionen för naturgeografi

   Författare :Bubaraye Ohiosimuan Dirikumo; [2023]
   Nyckelord :Pesticides; Ecological Risk Assessment ERA ; rice farming; Mekong Delta; PRIMET Model; Exposure Toxicity Ratio ETR ; species sensitivity distribution SSD ; predicted environmental concentrations PECs ;

   Sammanfattning : Pesticide use in rice farming is a common practice in the Mekong Delta and poses ecological risks to aquatic organisms, the environment, and human health. This study focused on the ecological risk assessment of pesticide use in rice farming using the PRIMET model as a decision support tool to evaluate the risks of pesticide exposure, ecotoxicity, and risk characterization, as well as employing the species sensitivity distribution (SSD) assessment model to calculate the potentially affected fraction (PAF) of species based on the computed predicted environmental concentrations (PECs) from PRIMET.
