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 WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
