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 ... -
Late Weichselian glacial dynamics and retreat patterns of the Fennoscandian Ice Sheet in Gausdal Vestfjell, southcentral Norway, acquired from spatial data
(PhD thesis;2018:68, Doctoral thesis, 2018)Evidence-based geomorphological research (analyses of glacial landform record) is one of the commonly used types of glacial reconstructions applied for studying the past ice sheets. The work covered by this thesis contains ... -
Impediments to forest recovery in bracken-dominated clearings in the African Highlands
(PhD Thesis;2018:70, Doctoral thesis, 2018)Vegetation dynamics in disturbed forested landscapes remain incompletely understood. Considerable areas with stalled forest recovery occur worldwide and may reflect the effects of dense and persistent understorey plants ... -
How termites and large mammalian herbivores influence tree communities, seed removal and wood decomposition in an African savanna
(PhD Thesis;2018:71, Doctoral thesis, 2018)The heterogeneity and extent savannas makes them resilient, diverse and socioeconomically important. Abiotic factors determine large-scale variation on a, but biotic factors matter at small-scales. In the African savannas, ... -
The effect of biochar in combination with mineral or organic fertilizers on crop production in Nepal
(PhD Thesis;2018:23, Doctoral thesis, 2018)The majority of poor people in Nepal relies on agriculture for employment and livelihood sustenance. Declining soil fertility and ongoing climate change are the key challenges faced by farmers, with adverse effects on crop ... -
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 ... -
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 ... -
Ecological impacts of red deer browsing in boreal forest
(PhD Thesis;2018:66, Doctoral thesis, 2018)The populations of wild ungulates are increasing in the northern hemisphere, and in many areas, their populations have developed from critically low to historically high numbers within the last century. There are multiple ... -
