1. Resource and Environmental Impacts of Resource-Efficiency Measures Applied to Electronic Products
Sammanfattning : Natural resources such as ecosystems, land, water and metals underpin the functioning of economies and human well-being, and are becoming increasingly scarce due to growth in population and affluence. Metals are increasingly demanded for their specific properties as modern technology develops. LÄS MER
2. On Sustainability of Biomass for Energy and the Governance Thereof
Sammanfattning : Due to concerns about climate change, energy security, and resource scarcity, non- renewable resources are increasingly being displaced by biomass. As with most human activities, the production of biobased products can be associated with negative impacts. Primarily, this relates to the biomass supply systems, i.e. LÄS MER
3. Felling Forests from Afar: Quantifying Deforestation Driven by Agricultural Expansion and International Trade
Sammanfattning : Deforestation is a major source of human-caused greenhouse gas emissions and the largest threat to terrestrial biodiversity. Most forest loss is due to the expansion of agricultural land use increasingly driven by international demand for food, fuel and fibre. LÄS MER
4. Where have all the forests gone? Quantifying pantropical deforestation drivers
Sammanfattning : Deforestation across the tropics continues to be a major source of greenhouse gas emissions and the largest threat to biodiversity on land. With strengthened commitments to reduce deforestation from countries and companies alike, it is crucial that renewed investments for reducing deforestation be guided by a sound understanding of what drives deforestation.

5. Studies of Volcanic Plumes with Remote Spectroscopic Sensing Techniques -DOAS and FTIR measurements on volcanoes of the Network for Observation of Volcanic and Atmospheric Change-
Sammanfattning : Volcanism is a rich geodynamical process, closely linked to the origin and ongoing evolution of the lithosphere, atmosphere, hydrosphere and biosphere. Humans have benefited from the resources provided by volcanoes but also been threatened by the dangers of volcanic eruptions, which accurate prediction remains elusive. LÄS MER
