1. Greenhouse Gas Fluxes and Carbon Sequestration in Young Norway Spruce Stands : The Effects of Fertilization
Sammanfattning : The enormous challenge of climate change is discussed and debated today because of its major impact on life on Earth. The forests have an important role to play as the plants absorb carbon dioxide (CO2) from the atmosphere through their photosynthesis and the growing tree retain carbon (C). LÄS MER
2. Natural and social dimensions of forest carbon accounting
Sammanfattning : Global forests store large amounts of carbon both in living biomass and in the soil. The ability of forests to counteract climate change by acting as carbon sinks have been recognized in global climate politics, such as the 2015 Paris agreement which calls for national commitments to reduce greenhouse gas emissions.

3. Modelling carbon uptake in Nordic forest landscapes using remote sensing
Sammanfattning : Boreal forests and peatlands store over 30% of the global terrestrial carbon in their vegetation and soil. but changing climate can compromise the current carbon stock. LÄS MER
4. Carbon exchange in boreal ecosystems: upscaling and the impacts of natural disturbances
Sammanfattning : Boreal forests and peatlands are globally significant carbon stores but they are threatened by rising air temperatures and changes in precipitation regimes and the frequency of natural disturbances. Predicting how the boreal biome will respond to climate change depends on being able to accurately model and upscale the greenhouse gas fluxes between these ecosystems and the atmosphere. LÄS MER
5. Impact of tree species on carbon in forest soils
Sammanfattning : Different tree species differ in productivity, litter quality and quantity, canopy structure and nitrogen deposition. Norway spruce (Picea abies), Scots pine (Pinus sylvestris) and birch (Betula pendula and B. pubescens) are the three dominant tree species in Sweden. LÄS MER
