Effect of Intensive Forestry on greenhouse emissions from Swedish forests. 2008

Background: Swedish forests act as large carbon sinks. But what will happen in the future if forest managers start applying nitrogen fertilizers to grow biofuel? Nitrous oxide (N2O) is 296 times more potent as a green house gas than carbon dioxide, and it stays in the atmosphere for 120 years. Tellus scientists from the University of Gothenburg are participating in a new research project that aims to find out.
	According to IPCC, anthropogenic N2O emission should be reduced by 50%. But very little is known about NO and N2O emissions from fertilised young forests, so firstly this needs to be studied more thoroughly. The project will then investigate net emissions resulting from different forestry fertilization strategies. This means looking not only at sequestration (in trees, soil, and wood products), but also carbon emissions from forest operations, avoided emissions due to wood product substitution of fossil fuels and non-wood products, and of course the emission of non-carbon GHGs like N2O. The overall aim i a holistic overview of how intensive forestry can contribute to a positive climate effect through decreased net GHG emission in Sweden.
Methods: The project will use the CoupModel to simulate how forests grow - and their greenhouse emissions - depending on the soil, the available nutrients, and the climate. Because the project will take a long-term view, looking at emissions over the next 100 years, this means the simulations must incorporate climate change. The Regional Climate Group at the University of Gothenburg are contributing downscaled climate change scenarios that can be used for the simulations. Participants: The project is a joint collaboration between SLU (Johan Bergh), Mid Sweden University (Leif Gustavsson) and Gothenburg University (Leif Klemedtsson). The climate modelling will be linked to the GU Tellus platform, and is begin conducted by David Rayner under the supervision of Prof. D. Chen, and done in co-operation with the Rossby centre.

IRWIN - Improved local road winter index to assess maintenance needs and adaptation costs in climate change scenarios. 2008

Background: Roads become slippery and dangerous when temperatures are close to zero, and salting is a winter maintenance activity that can help. Should road owners expect to perform more salting under climate change conditions? What about snow ploughing - climate change scenarios show more winter precipitation in Sweden. A new project involving the Regional Climate Group at the University of Gothenburg is investigating.
Improved tools for road owners are urgently needed to help them cope with rapidly progressing climate change. Scenarios with good spatial and temporal resolution that show the climate we might expect in the future, especially regarding severe weather events, are a very important tool for planning activities. Traditionally, downscaled climate change scenarios are calculated using ordinary meteorological data. But meteorological station data is not the most appropriate data for describing road climate conditions.
Methods: The idea of IRWIN is to combine the best climate change scenarios from Global Climate Models (GCMs) with data from field stations from the Road Weather Information systems (RWIS) used by many countries. These stations are located along important road networks, and provide accurate information about road climate. The goal of IRWIN is to use this new dataset to develop an improved winter road index which can be used to assess the costs and benefits of various winter maintenance strategies. Participants: The IRWIN project participants and their representatives are Foreca Consulting Ltd, Finland (Pirkko Saarikivi), Klimator AB, Sweden (Torbjörn Gustavsson) and Department of Earth Sciences, University of Gothenburg, Sweden (Dave Rayner). Funding: IRWIN is funded as a joint research project through "ERA-NET ROAD - Coordination and Implementation of Road Research in Europe", a Coordination Action funded by the 6th Framework Programme of the EC.
