Ample Rare Elements: A Geochemical Anomaly in the Earth's Crust at Norra Kärr
(2021-11-18)The Norra Kärr alkaline complex in southern Sweden (58°06’N, 14°34’E) is a classic occurrence of agpaitic rocks, which contains a large mineral deposit of rare-earth elements (REE), Zr, and Nb. The complex consists of ... -
Changes in near-surface winds across Sweden over the past decades - Observations and simulations
(2020-11-19)Driven by a combination of anthropogenic activities and climate changes, near- surface terrestrial winds displayed a large decrease in their magnitude in the past decades, named “stilling”, and a recent recovery in their ... -
Changes of evapotranspiration and water cycle in China during the past decades
(2010-02-09)Evapotranspiration is the second largest quantity in the water cycle and an important indicator for climate changes. Accurate estimations and better understanding of evapotranspiration are required in hydrologic studies ... -
Characterizing and reconstructing 500 years of climate in the Baltic sea Basin
(2009-05-13)Climate has always attracted considerable interest, and climate observations have been made in various ways for most of human history. Regional climate and how it varies is of particular interest, as it sets the scene for ... -
Climate regulation provided by urban greening - examples from a high latitude city
(2015-11-06)Cities exert a strong influence on urban climate, and consequently on human health and wellbeing. This increases the importance of considering climate issues in urban planning, particularly in the context of global climate ... -
Cold-climate landforms on Mars and Earth-analogues in Svalbard
(2012-09-14)Periglacial landforms on Earth reflect cold-climate conditions and are intimately related to processes due to the presence of ground ice and perennially frozen ground, permafrost. The overall objective of this thesis is ... -
Crystallization and Differentiation Processes in the Thin Layered Alkali Gabbroic Intrusions of the Ulvö Gabbro Complex, Central Sweden
(2009-10-22)Fractional crystallization of magma is a commonly invoked mechanism for chemical differentiation in systems that range from volcanoes to entire planets. However, the processes that control separation of crystals and liquids ... -
Energy Efficiency in Winter Road Maintenance - A Road Climatological Perspective
(2015-05-07)Practices in winter road maintenance are dependent on the climate and weather impacting roads and the road users’ requirements. As in many other fields of transportation, it is of interest to investigate fuel efficiency ... -
Fluid Migration and Brittle Tectonothermal Evolution in the Central Fennoscandian Shield - Recorded by Fracture Minerals and Wall Rock Alteration
(2009-04-16)The Forsmark area in central Sweden has been investigated as a potential geological host for a final repository of spent nuclear fuel by the Swedish Nuclear Fuel and Waste Management Company (SKB). High quality drill core ... -
Forest and land use mitigation and adaptation in Sri Lanka – Aspects in the light of international climate change policies
(2012-03-05)As a developing island nation, Sri Lanka is vulnerable to the possible impacts of climate change. The land use and forestry sector accounts for a large part of Sri Lanka’s greenhouse gas emissions and can play a major ... -
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, ... -
Lustgasavgång från jordbruksmark
(Jordbruksverket, 2009)Regeringen fattade den 26 juni 2008 beslut om ändring av Jordbruksverkets regleringsbrev rörande uppdraget ”Åtgärdsprogram för minskade växtnäringsförluster” vilket ersätts av uppdraget; ”Jordbruksverket ska efter samråd ...
