Agriculture and Nature Panel Istanbul 2013

1. Agriculture and Nature PanelIstanbul 2013 Nick Hutchings, Barbara Amon and Rainer Steinbrecher

2. Agenda • Report on selective Guidebook updating • Suggested changes to reporting codes • N sources and emissions in Turkey • Agriculture and Nature/EPMAN/EPNB meeting • Work programme for next year

3. Revised chapters • 4B Manure Management • New NMVOC emission factors – Tier 1 and Tier 2 • Update PM emission factors – Tier 1 and Tier 2 • 4D Crop production and agricultural soils • Updated the NMVOC emission factor – Tier 1 • Consistency of PM emission factor • Updated NH3 emission factors from mineral fertiliser – Tier 1 and Tier 2 • 4F Field burning of agricultural wastes • New/updated NMVOC emission factors - Tier 1 and 2

4. 4B Animal husbandary/manure management • NMVOC- No existing default emission factors • Few European data • Large studyundertaken in USA • mainlycattle, poultry and pigs • housing not manurestorage or fieldapplication • Extrapolate to European conditions • Likely to be a significant source • Acceptance of emission factors but need for clearer presentation in Guidebook

5. 4B Animal husbandary/manure management • PM emissions • Incorrect references • Incorrect emission factors • Some missing emission factors • Correctederrors • Providedadditional emission factors • Accepted

6. 4F Field burning of agricultural wastes • PM emissions • Error in emission factors • Correctederrors • Black carbon and copper – new Tier 1 and 2 emission factors • Accepted

7. 4D Crop production and agricultural soils • NMVOC emissions • Incorrect reference and units (Tier 1) • Corrected error – new Tier 1 emission factor • Accepted

8. 4D Crop production and agricultural soils • Ammonia emissions from fertilisers • Undocumented emission factors • Literaturereview of ammonia emissions in the field • No effect of temperature • Effect of soil pH on ammonium sulphate and ammonium phosphateonly • Calculated new emission factors from data collated • Significantdecreases and increases in emission factors • Large impact

9. Revised chapters • Accepted but need for • Some clarification concerning calculation of emission factors – email • Some improvements in description of methodologies • Follow-up concerning ‘out-of-scope’ issues • Incorporate in revised text or added to workplan

10. Suggested changes to reporting codes • Proposedchangeswouldresult in aggregation/lack of detail • Strategy: • Use the new CRF codes but adddetail • Retain the currentstructure as far as possible • Requiresomeclarificationconcerningdetails of CRF codes

11. Proposed Current

12. N source and emissions in Turkey • See presentation on TFEIP website (Agriculture and Nature Expert Panel) • Good activity data for agriculture

13. Agriculture and Nature/EPMAN/EPNB meeting • Task Force on Reactive Nitrogen (TFRN) • Expert Panel on Mitigation of Agricultural Nitrogen (EPMAN) • Expert Panel on Nitrogen Budgets (EPNB) • TFRN expert panels containexperts in nitrogen emissions - source of expertise for TFEIP • Maintaincollaboration • Barbara Amon co-chair of Expert Panel on Mitigation of Agricultural Nitrogen

14. Workplan 2013-2014 • Follow-up on discussions at Emission Inventory Compilers and Users Workshop • Ammonia emissions from crops • Continue discussion on harmonisation with revised reporting codes • Ensure that out-of-scope comments from selective GB revision are included in revised GB or added to workplan 14

15. Workplan 2013-2014 (cont) • Continue and intensify the collaboration with TFRN/EPMAN • Provide guidance on reporting emissions from anaerobically digested manure • Intensify the communication with EECCA countries on inventory preparation and mitigation options • Investigate better use of Emission Factor Database 15
