Policy brief launched

Policy Brief on mitigation options for reactive N losses launched: Addressing nitrous oxide: An often ignored climate and ozone threat

Lead scientists from around the globe recently came together for a meeting in Garmisch-Partenkirchen, Germany supported by the OECD Co-operative Research Programme: Biological Resource Management for Sustainable Agricultural Systems. They exchanged and assessed the latest knowledge and agreed that, despite uncertainties and the need for additional research on processes driving N2O emissions, there is sufficient knowledge available to implement immediate action towards reducing N pollution, specifically N2O emissions. The actions listed below demand a more efficient use of fixed and reactive nitrogen in order to reduce greenhouse gas emissions and other forms of N pollution from agricultural systems.

Database - Steering commitee meeting

17. April 2019

To discuss the next steps for establishing a global nitrous oxide database, project partners came together at IMK-IFU in Garmisch-Parthenkirchen. The goal of the database is to gather nitrous oxide flux data from agricultural sites across the globe in a standardized format in order to facilitate model validation and development. A synthesis effort for nitrous oxide fluxes will enable to better estimate and quantify global nitrous oxide fluxes from agricultiral soils.

 

 

International workshop on climate change, reactive nitrogen, food security and sustainable agriculture

15-16.April 2019

Our international workshop on climate change, reactive nitrogen, food security and sustainable agriculture brought together leading experts in the field of food security, soil science and agricultural greenhouse gas emissions. The workshop enabled to discuss the current knowledge on and establish a global research network for N2O mitigation and denitrification in fertilised cropping systems. The participants presented latest research findings and policy developments on the trade-offs between crop productivity, N fertilizer use, and GHG emissions of agricultural ecosystems around the globe, with the aim of identifying hotspots and knowledge gaps of denitrification and N2O emissions, reducing uncertainty of flux estimates, and establishing consistent standards for methodologies. This workshop provided a framework for international cooperation in key research and policy areas of food, soil, water and climate change.
