  1. 1. 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. 2. 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

  4. 3. Evaluation of SLAM based mobile laser scanning and terrestrial laser scanning in the Kiruna mine : A comparison between the Emesent Hovermap HF1 mobile laser scanner and the Faro Laser Scanner Focus3D X 330 terrestrial laser scanner

    University essay from Högskolan i Gävle/Samhällsbyggnad

    Author : Claes Gustafsson; [2023]
    Keywords : Terrestrial laser scanning; mobile laser scanning; simultaneous localization and mapping; underground mapping; Kiruna mine.;

    Abstract : The mining industry has over the last few decades seen a drastic increase in the usage of laser scanning technologies as a way of creating 3D maps of the mines being exploited. Underground mapping in places such as mines has become more prevalent as the technology has progressed and made it easier to generate highly detailed point clouds faster. READ MORE

  5. 4. Pathways towards universal access to electricity in West Africa : Case study of Mali and Senegal

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Vittorio Bozzo; [2023]
    Keywords : Universal electricity access; Senegal; Mali; OnSSET; GIS; PV mini-grid; Universell tillgång till el; Senegal; Mali; OnSSET; GIS; PV mininät;

    Abstract : Despite the vast solar potential in both Mali and Senegal, the electricity access in both countries remains one of the lowest in the world. The main problem is represented by the disparity between rural and urban settlements. In Senegal, the electricity access for rural areas was lower than 50%, while in Mali was around 35%. READ MORE

  6. 5. Potential migration routes for the alien species, pink salmon (Oncorhynchus gorbuscha) : investigating access in west and south coast rivers of Sweden

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Rebecca Martin; [2023]
    Keywords : invasive; alien species; salmonid; anadromous; migration barriers;

    Abstract : Invasive alien species are one of the main drivers of ecosystem change globally, presenting challenges to biodiversity that take many forms Pink salmon, Oncorhynchus gorbuscha, has recently been observed on the Swedish west coast where its presence is the result of secondary spreading from populations introduced to the White and Barents Seas in northwestern Russia. In Sweden, O. READ MORE
