Sammanfattning : Lake ecosystems receive, transmit and process terrestrial carbon and thereby link terrestrial, aquatic and global carbon cycles. Most lakes evade CO2 to the atmosphere, but the annual magnitude of CO2 evasion, as well as sources and mechanisms underpinning CO2 evasion from lakes are still largely unresolved. LÄS MER

18. Assessing the sustainability of bioethanol production in different development contexts: A systems approach
Sammanfattning : The continuous depletion of fossil fuel reserves, the global agenda on climate change and threats to energy security have led to increased global interest in the exploration, production and utilisation of bioenergy and biofuels. Access to modern bioenergy carriers derived from the efficient conversion of locally available biomass resources is indispensable for economic growth, rural development and sustainable development in developing countries.

19. Reconstructing Noah’s ark : Integration of climate change adaptation into Swedish public policy
Sammanfattning : Due to expected impacts such as flooding, landslides, and biodiversity loss, climate change adaptation has become recognized as an inevitable part of climate change policy and practice. However, our understanding of how to organize the management of adaptation is lacking, and few concrete measures have yet been implemented. LÄS MER
20. Influential factors in simulations of future urban stormwater quality : Climate change, progressing urbanization and environmental policies
Sammanfattning : Climate change is regarded as one of the main future challenges implyingchanging hydrological conditions in urban areas. At the same time many urbanareas are expected to grow due to increasing population, which will most likelycause a higher level of urbanization. LÄS MER
