6 th FRAMEWORK PROGRAMME PRIORITY 6. 3 - GLOBAL CHANGE AND ECOSYSTEMS Nitro. Europe IP The nitrogen cycle and its influence on the European greenhouse gas balance
Context: Resource and delivery The Resources NEU, COST 729, ESF Nin. E, … ¨ Cluster: European Transboundary Nitrogen Activity (ETNA) ¨ Delivery target audiences European Commission ¨ International Conventions: WGs and negotiations ¨ International Nitrogen Initiative (INI): European Nitrogen Centre (ENC) ¨ Education and local stakeholders ¨
Multi-pollutant interactions for nitrogen Nitrous oxide (N 2 O) Further NO & N 2 O Nitric oxide (NO) NH 4 NO 3 in precipitation Ammonia (NH 3) Nitrate leaching NO 3 - Nitrate in streamwaters Abatement may swap one pollutant for another in the nitrogen cascade

Nitro. Europe IP n What is the effect of reactive nitrogen supply on the direction and magnitude of net greenhouse gas budgets for Europe? n Effect of N on GHG balance: Positive effect Unclear N 2 O (inc. 2’ sources) uptake in plants Cattle CH 4 wetlands n Negative effect C SOM decomposition To what extent would a more-integrated management of the N-cycle and its interactions with the C-cycle have potential to reduce greenhouse gas and Nr emissions simultaneously?

Component 1: NEU Flux Network Tiered structure: n Level 3 (“Super Sites”): N and GHG fluxes: Core Measurements + Special Topics. Includes high cost micromet methods and process analysis. n Level 2 (“Regional Sites”): Basic N and GHG flux monitoring, e. g. COTAG, simple cuvettes n Level 1 (“Inferential Sites”): Basic N air concentration measurements at 50 CO 2 flux sites. e. g. DELTA low cost denuders.

ESF – Research Network Programme Nitrogen in Europe (Nin. E) n n n Running for 5 years, started March 2006 Aims to integrate European research and researchers Delivering an assessment report of the state of European nitrogen, sources, transformations and impacts, as well as establishing a basis to recommend future solutions
COST Action 729 Assessing and managing nitrogen fluxes in the atmospherebiosphere system in Europe ¨ ¨ ¨ Combining knowledge of various research areas to provide a scientific basis for an integrated approach to nitrogen management; requiring knowledge on: The formation of reactive nitrogen and the resulting emissions to the atmosphere Transport, transformation and deposition Integrated assessment modelling Policy analysis and support www. cost 729. org
