Drained wetlands give off same amount of greenhouse gases as industry

23.11.2012
Drained wetlands in Sweden account for the same amount of greenhouse gas emissions as Swedish industry. This is shown by a summary of research from the University of Gothenburg, Sweden and the Swedish University of Agricultural Sciences.
Forests and agricultural fields on drained previous wetlands make up between five and ten percent of Sweden’s surface area. When these wetlands are drained, they become a significant source of greenhouse gas emissions.

“We note that drained wetlands which have been forested or used for agricultural purposes are a significant potential source of greenhouse gases of a magnitude that is at least comparable with the industrial sector’s greenhouse gas emissions in Sweden.”

Emissions from these drained wetlands can be reduced, but that involves rewetting the land – resulting in a negative impact on forestry production. According to the researchers, compromises may be necessary.

“As long as wetlands remain wet, only methane is given off,” says Åsa Kasimir Klemedtsson from the Department of Earth Sciences at the University of Gothenburg. “However, for more than a hundred years land has been drained for agriculture and forestry, producing large quantities both carbon dioxide and nitrous oxide.”

Together with researcher Örjan Berglund from the Swedish University of Agricultural Sciences, Dr Kasimir Klemedtsson was commissioned by the Swedish Environmental Protection Agency during the summer and autumn of 2012 to compile information about greenhouse gases from drained wetlands.

New rules were introduced at last year’s Durban Climate Change Conference with the second Kyoto Protocol phase. These rules include the possibility of reporting wetland drainage or rewetting of drained wetlands. Sweden now faces the choice of whether to include these ahead of the second Kyoto Protocol phase.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
