Although drained areas for the purposes of forestry and agriculture cover only a few per cent of Sweden’s total surface area, they release enormous amounts of greenhouse gases such as carbon dioxide and nitrous oxide.
‘Greenhouse gas emissions from former peat lands make up about one-fifth of Sweden’s total reported emissions of greenhouse gases. This is roughly the same amount as the country’s entire industrial sector emits through energy consumption,’ says Åsa Kasimir Klemedtsson, researcher at the Department of Earth Sciences, University of Gothenburg.
Sweden’s reporting of greenhouse gas emissions to the United Nations Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol is seemingly very precise, but by combining the contributions from drained peat lands with the CO2 uptake by forests into a net figure, these emissions are in effect hidden.
‘As the amount of carbon stored in forests is increasing, the emissions from drained peat lands become invisible. And this may explain why measures to reduce these emissions haven’t been discussed to the extent they deserve,’ says Kasimir Klemedtsson.
The second commitment period of the Kyoto Protocol started this year, with new rules for how greenhouse gas emissions from drained peat lands can be reported. This has brought attention to the issue. This autumn, the UN’s climate panel, IPCC, will publish the fifth evaluation report, and also new guidelines for how greenhouse gas emissions due to draining of wetlands should be calculated.
A workshop is currently being planned to shed light on the problem.
‘The purpose of the workshop is to bring attention to and discuss emissions of greenhouse gases from drained wetlands. We want to describe the amounts emitted, how they are reported and which actions could help reduce them. We also want to illuminate what authorities and business actors are doing to limit the emissions, and what else needs to be done,’ says Kasimir Klemedtsson.
The workshop is hosted by the Gothenburg Atmospheric Science Centre (GAC), which is a centre for atmospheric research in the Gothenburg region, and BECC (Biodiversity and Ecosystem Services in a Changing Climate), which is a collaboration between Lund University and the University of Gothenburg.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
