Impact of climate variability on dynamic groundwater storage in mid- to high latitude countries
(2022-04-07)Climate change will alter the hydrological cycle, potentially changing dynamic groundwater storage and increasing groundwater drought risk. Climate influences groundwater storage directly via changes in groundwater ... -
Impact of climate warming on Arctic plant diversity: phylogenetic diversity unravels opposing shrub responses in a warming tundra
(2022-10-13)The Arctic biome is at significant risk, with recent observations suggesting that climate change is warming the Arctic nearly four times faster than the global average. Last decade, evidence from experimental warming ... -
Instruments for reaching climate objectives. Focusing on the time aspects of bioenergy and allocation rules in the European Union's Emission Trading System
(2011-09-29)The Europeans Union’s (EU’s) climate and energy strategy aims at reducing the emissions of greenhouse gases (GHG) by 20 % (compared to 1990) and to increase the share of renewable energy to 20 % by the year 2020. Increased ... -
Land use GHG emissions and mitigation options, simulated by CoupModel
(2015-12-09)Climate change and greenhouse gas (GHG) emissions are one of the major challenges to the humankind of 21st Century. This thesis focuses on understanding, estimating and suggesting mitigation of the GHG emissions (mainly ... -
Land Use in Climate Policy - Forest Based Options at Local Level with Cases from India
(2009-11-06)With India’s large population, an increased pressure on forest and agricultural land indicate a growing demand for environmental services that is sustainable for the future. Fertile agricultural land is limited and with ... -
Late Holocene spatiotemporal hydroclimatic variability over Fennoscandia inferred from tree-rings
(2014-01-27)There is a broad scientific consensus that the global climate is changing, and that human activity is a significant factor contributing to the change. The response of the hydrological cycle to the warming is far reaching, ... -
MODEL STUDIES OF FISH EGG AND LARVAL TRANSPORT IN THE KATTEGAT AND THE NORTH ATLANTIC
(2013-03-06)For the early life stages of fish, the dispersal and retention are important factors regarding present and future survivorship, growth and reproduction. The main objective of this thesis is to analyse fish egg and larval ... -
Modelling of the daytime and night-time urban thermal environment
(2016-03-11)The world’s urban population is expected to increase over the coming decades. To maintain and improve the health and well-being of urban citizens, it is important to increase our knowledge and develop methods for evaluating ... -
Modelling the Dissolved Inorganic Carbon System in the Baltic Sea
(2013-10-04)Oceans are capable of storing part of the emitted anthropogenic carbon dioxide (CO2) due to the formation of carbonic acid and subsequent dissociation. CO2 is also assimilated by biota and the inorganic carbon system is ... -
Nitrogen Losses from a Clay-rich Soil used for Cereal Production in south-western Sweden
(2021-11-24)Addition of fertiliser nitrogen (N) in crop production increases yields and protein contents, but all is not taken up by the crop. Instead, some of the N is lost to air and waters, contributing e.g. to climate change, ... -
Nitrous Oxide Production in Agricultural Soil – Linking Biogeochemical Pathways and Drivers
(2018-05-09)Nitrous oxide (N2O) is a long-lasting and potent greenhouse gas responsible for depletion of stratospheric ozone. As the atmospheric N2O concentration reaches all-time highs, emission variability in space and time still ... -
Observed and simulated changes in extreme precipitation and cold surges in China: 1961–2005
(2013-02-01)In the present work, precipitation and temperature related climate extremes are examined, with a focus on Mainland China. The objectives of this study are a) to identify targeted climate extremes and their changes during ... -
Observing and Modeling Precipitation in the Tibetan Plateau region - from large-scale processes to convective storms
(2023-02-20)Climate change in mountain regions has far-reaching societal impacts such as increased risks for natural hazards and water scarcity that may affect billions of people in the downstream regions. Precipitation changes play ... -
Ocean Climate Variability over Recent Centuries Explored by Modelling the Baltic Sea
(2009-09-03)Natural variability and anthropogenic factors both contribute to changes in the ocean climate of the Baltic Sea. Observations over the past century indicate that changes in environmental settings and ocean climate have ... -
Oceanographic studies of the Baltic Sea with emphasis on sea ice and mixing processes
(2009-05-06)This thesis comprises of model estimates of the water and heat budgets, re-estimating of the budget of deep-water mixing energy, model studies of generation mechanisms for internal waves, sea ice dynamics and finally sea ... -
Outdoor heat in urban areas - Model development and applications
(2022-05-10)Heat waves and high outdoor air temperature can lead to heat stress with negative implications for human health and wellbeing such as heat stroke, heat cramps, dehydration and in extreme cases death. The urban population ... -
Phosphorus recycling in brackish and marine environments - Sediment investigations in situ in the Baltic Sea and the By Fjord
(2012-11-29)The phosphorus load to the oceans from land started to increase since around 1950 when man started to mine phosphorus-mineral from phosphorus-rich soils and bedrock. The increased use of phosphorus fertilizers in agriculture ... -
Precambrian Crustal Evolution of the Rehoboth Province, Southern Africa
(2013-05-08)This thesis uses U-Pb, Sm-Nd Lu-Hf, Ar-Ar and Oxygen isotope data on well-documented rock samples, to investigate crustal evolution of the Precambrian Rehoboth Province of Southern Africa. This province is defined by its ... -
Predicting Spatial and Stratigraphic Quick-clay Distribution in SW Sweden
(2014-05-12)Clay sediments are associated with a wide variety of engineering problems, of which landslides, together with settlement, are the most investigated due to the large associated costs. Quick-clay deposits, which if disturbed ... -
