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.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
