1. A Changing Arctic Climate : Science and Policy in the Arctic Climate Impact Assessment
Sammanfattning : Climate change has often been framed as a global issue but slow progress in the global climate negotiations and an increasing need to plan for local adaptation have made it increasingly salient to also discuss the potential of other arenas for climate policy and knowledge production. This dissertation analyzes the interplay between science and policy at the international regional level based on a study of an assessment of the impacts of climate change in the Arctic. LÄS MER
2. Greenhouse gas emission from tropical reservoirs : Spatial and temporal dynamics
Sammanfattning : The emission of methane (CH4) and carbon dioxide (CO2) from reservoirs has been estimated to make up for about 1.3% of the global anthropogenic greenhouse gas emission. The impoundment of a river leads to the accumulation of sediment that is brought in from inflowing rivers, and the sediment organic matter is degraded to CH4 and CO2. LÄS MER
3. Permafrost Groundwater Dynamics : Modeling of vertical and lateral flows in the active layer across multiple scales
Sammanfattning : Hydrological processes in the Arctic are profoundly influenced by the presence of permanently frozen ground, known as permafrost. Conversely, permafrost is greatly affected by hydrological changes resulting from climate change. LÄS MER
4. Konkurrensklimat och dynamik : en studie av interaktion mellan konkurrenter
Sammanfattning : A partly new train of thought has emerged during the last few years, which claims that national conditions are of importance for company strength in relation to international competitors. National competition has stood out as one of the most important explanatory factors, and is seen as the catalyst or motor in dynamic industrial environments. LÄS MER
5. Rooting for forest resilience : Implications of climate and land-use change on the tropical rainforests
Sammanfattning : Tropical rainforests in the Amazon and Congo River basins and their climate are mutually dependent. Evaporation from these forests help regulate the regional and global water cycle. Furthermore, these rainforests themselves depend on precipitation to sustain their structure and functions. LÄS MER
