Greenhouse gases from forest soils
Date:4/12/2011

ide emissions due to the combustion of fossil fuels or biomass burning.

Increased deposition of reactive nitrogen on forests does not only cause climate-damaging nitrous oxide emissions from forest soils, but also a loss of diversity of plant and animal species and enhanced nitrate emissions into water.

When presenting the ENA study in Edinburgh, Professor Klaus Butterbach-Bahl emphasised: "The present atmospheric reactive nitrogen deposition is much too high. Our analysis shows that significant reductions in particular of ammonia emissions from agricultural activities are needed to reduce nitrous gas emissions from forest soils."

Klaus Butterbach-Bahl is professor at Karlsruhe Institute of Technol-ogy (KIT). He is heading the Atmospheric Environmental Research Division of the Institute of Meteorology and Climate Research (IMK-IFU) and lead author of the ENA chapter on reactive nitrogen as a threat to the European greenhouse balance.

The ENA study is the first study describing the multiple threats of nitrogen pollution, including its ecological and economic impacts, i.e. its contribution to climate change and biodiversity loss on the European scale. The ENA study also identifies the regions at greatest risk in Europe and outlines actions to be taken to reduce the risks to protect the environment and public health.
