(PhD Thesis;2010:33, Doctoral thesis, 2010)Pastoralists have been using arid and semi-arid rangelands to produce their livelihood outputs through livestock production for centuries. However, recent changes in land use and associated impacts on biodiversity and ... -
The agronomic and environmental effects of biochar under field conditions in Norway
(PhD Thesis;2021:84, Doctoral thesis, 2021)Biochar is emerging as a promising solution for increasing carbon in soil, improving the fertility of selected soils, and mitigating N2O emissions from agricultural soils. In Norway, biochar is high on the agenda of potential ... -
An experimental study on rotor-wake interactions of wind turbines
(PhD Thesis;2018:55, Doctoral thesis, 2018)Interactions of wind turbine wakes with downstream turbines can reduce a wind farm’s power production and increase loads on the individual turbines. For the purpose of wind farm optimization, different aerodynamic ... -
Analyses of the use of the Norwegian forest sector in climate change mitigation
(PhD Thesis;2011:28, Doctoral thesis, 2011)The forest sector plays important roles in the global carbon cycle. Firstly, the global carbon cycle. Firstly, the global carbon storage in forest biomass and soil is of a considerable size, and the total carbon sequestration ... -
Analyzing aspects of land-use sustainability in Tanzania : current forest degradation, urban charcoal demand, and impacts of future firewood and charcoal consumption
(PhD Thesis;2019:51, Doctoral thesis, 2019)The forest sector plays a significant roles both directly and indirectly in Tanzania. In total 54% of the land area of mainland Tanzania is covered by different types of forests, the main ones being the miombo woodlands, ... -
Angling tourism and landowner based management of Atlantic salmon stocks in the Trondheim fjord region of Norway
(PhD Thesis;2011:26, Doctoral thesis, 2011)Angling for Atlantic salmon (Salmo salar L.) is a popular recreational activity and provides income for Norwegian landowners holding fishing rights. Abundance and distribution of salmon have however declined markedly during ... -
Applicability of natural porous materials and lime with conditioning and sorption properties for wastewater treatment
(PhD Thesis;2016:77, Doctoral thesis, 2016)Urban wastewater streams are produced in large quantities and removal of contaminants is required for compliance with environmental regulations. The water separation, concentration of particles as solid phases (e.g., ... -
Assessments of the future role of bioenergy in the Nordic energy and forest sectors
(PhD Thesis;2020:64, Doctoral thesis, 2020)This thesis presents studies that describe different consequences of increased use of forest resources for energy purposes. Forest biomass is widely used in many different applications; in recent years, biofuel has been ... -
Bio-economic aspects of moose : forage interactions - gains and compromises of interdisciplinary research
(PhD Thesis;2010:27, Doctoral thesis, 2010)Interdisciplinary research is a prerequisite for applied progress in natural resource management. Still, most relevant studies are done by economists alone, and not in collaboration with ecologists. I discuss the ideological ... -
Biochar for N2O mitigation and improved delivery and retention of mineral nitrogen in compost and soil
(PhD Thesis;2022:15, Doctoral thesis, 2022)Biochar is a promising technology for simultaneously storing carbon in soils, improving crop yields and reducing greenhouse gases. In the last 20 years, research efforts into biochar and its application to soils have been ... -
Biomass estimation models and methods for miombo woodlands of Malawi using field and remotely sensed data
(PhD Thesis;2016:92, Doctoral thesis, 2016)Dry tropical forests, such as the miombo woodlands, play an important role in the global carbon budget as well as in contributing towards the sustainable development of countries such as Malawi. To ensure sustainability ... -
Characterization of radioactive particle exposure using micro and nano-focused X-ray techniques
(PhD Thesis;2021:95, Doctoral thesis, 2021)Radionuclides may be introduced into the environment from a variety of sources both naturally occurring, such as weathering from ore deposits, and anthropogenic, such as releases associated with the nuclear weapons and ... -
