Advancing tree species composition prediction in boreal forests with remote sensing
(PhD Thesis;2025:42, Doctoral thesis, 2025)Accurate tree species composition information is crucial for forest management, influencing harvest scheduling, regeneration choices, and silvicultural treatments. In operational forest management inventories (FMIs), ... -
Volatile organic compound emission from wood building materials : impact on indoor air quality
(PhD Thesis;2025:16, Doctoral thesis, 2025)In the last 30 years, there has been a global trend towards the increased adoption of modern timber building materials such as Cross-Laminated Timber (CLT), glulam, and wood fiber-based insulation in the construction ... -
Environmental effects on the free-living stages of parasitic nematodes : insights from an Arctic ecosystem
(PhD Thesis;2025:11, Doctoral thesis, 2025)Parasites - species that use a host as habitat and nutrient source while having deleterious effects on this host - can play important roles in ecosystems. Parasitic nematodes, a group of parasites referred to as roundworms, ... -
Nature-culture interactions in Norwegian summer farming landscapes : an integrating approach to the past and for the future
(Dr. Philos. Thesis;2025:1, Doctoral thesis, 2025)This thesis aims to document, discuss, and get a deeper understanding of how heritage values and natural resources in the summer farming landscape interact and can be maintained for the future. The integrated relationship ... -
Advancing site index determination using point cloud data
(PhD Thesis;2024:70, Doctoral thesis, 2024)Site index (SI) is the top height at a given reference age and is used to describe the forest site’s potential to produce wood volume. SI determination has evolved from purely field-based assessments based on age and height ... -
Historical and contemporary drivers of organic soil and charcoal carbon stocks in boreal forests
(PhD Thesis;2024:71, Doctoral thesis, 2024)Boreal forests are evergreen landscapes that store vast amounts of carbon belowground in the form of soil organic carbon (SOC). These ecosystems act as carbon (C) sinks in their natural state as long as temperatures ... -
Modelling radionuclide transfer along terrestrial food-chains : conceptual enhancements and region-specific adaptations
(PhD thesis;2024:74, Doctoral thesis, 2024)Models are one of the key tools employed by emergency and response organizations. They play an important role in the assessment of the potential consequences of a nuclear accident and prognosis of its possible progression. ... -
Effect of biochar and crop rotation with pigeon pea on plant available phosphorus under Conservation Agriculture
(PhD thesis;2024:31, Doctoral thesis, 2024)Climate change and variability pose a major threat on household food security in Southern Africa especially on smallholder farms in areas with low, erratic, and highly variable rainfall with frequent droughts. The effects ... -
Brown trout anadromy in the Anthropocene
(PhD Thesis;2024:50, Doctoral thesis, 2024)Recent human-induced changes in both marine and freshwater environments are likely to alter adaptative landscapes in migratory species that utilise both habitats. Anadromous salmonids, like the brown trout (Salmo trutta), ... -
Vulnerability and impacts on peatlands and groundwater by tunnelling in crystalline rocks
(Dr.philos Thesis;2017:01, Doctoral thesis, 2017)The overall aim of the thesis was to contribute to improve the understanding and basis for assessments of environmental consequences and vulnerability of peatlands to morphological effects and hydrological changes caused ... -
Geophysical monitoring of redox influenced degradation near the water table
(PhD Thesis;2018:75, Doctoral thesis, 2018)Soil contamination of organic origin is a major environmental challenge. Redox reactions drive organic matter degradation in the ground. Monitoring these reactions is therefore needed to protect soil and groundwater. This ... -
Water storage dynamics of papyrus wetlands and land use change in the Lake Kyoga basin, Uganda
(PhD thesis;2018:69, Doctoral thesis, 2018)Papyrus wetlands of the upper Nile basin in Eastern Africa provide water and fertile soils that are essential to sustain agricultural production. Due to the need to improve food security, there is increased pressure to ... -
Fusion of airborne laser scanning and hyperspectral data for predicting forest characteristics at different spatial scales

Data, models, and insights for informed decision-making in the management of exclosures in Tigray, northern Ethiopia
(PhD Thesis;2018:89, Doctoral thesis, 2018)In Ethiopia, exclosures are rapidly expanding and performing good to reverse deforestation and land degradation. Local communities, particularly in Tigray show a clear preference for exclosures, which are useful for ecosystem ... -
Isocyanic acid : methodologies for generation, sampling and measurement in workroom air
(PhD Thesis;2018:27, Doctoral thesis, 2018)Isocyanates are mainly used industrially for the production of polyurethane (PUR) products. Thermal decomposition of PUR results in the emission of isocyanates. Workers performing hot-work such as grinding, welding and use ... -
Biomass stock and change estimation in boreal forests using remotely sensed data : results from empirical studies and simulations
(PhD Thesis;2017:69, Doctoral thesis, 2017)Airborne LiDAR (Light Detection and Ranging) has become an important remote sensing tool for forest inventory. In the past two decades, this technology has seen a rapid status transition from experimental to operational, ... -
Detection of root, butt, and stem rot in Picea abies with remotely sensed data
(PhD Thesis;2023:28, Doctoral thesis, 2023)Root, butt, and stem rot fungi (RBSR) are among the most significant forest pathogens in Norway. RBSR leads to decay of the tree stem and disruption of vascular tissue. Impaired vascular function reduces tree growth and ... -
Risk and uncertainties incorporated in the management of root and butt rot infected forest areas
(PhD Thesis;2022:75, Doctoral thesis, 2022)Root and Butt Rot (RBR) caused by the pathogenic fungi Heterobasidion spp. is a significant problem affecting Norway's main coniferous tree species, Norway spruce (Picea abies L. Karst) and Scots pine (Pinus sylvestris ... -
Application of external prediction models in forest management inventories based on airborne laser scanning
(PhD Thesis;2022:28, Doctoral thesis, 2022)The use of airborne laser scanning (ALS) data in forest management inventories (FMI) has become operational during the last decades. Since it was introduced, ALS has improved FMI practices due to their capability to describe ... -
