AARHUS UNIVERSITY Agriculture and Nature Expert Panel Report to plenum Nick Hutchings, Barbara Amon 1 Zagreb, 17 May 2016

AARHUS UNIVERSITY Ammonia emissions from fertilisers Need to finalise the methodology Improvements needed in the clarity of the text Written comments will be sent by several Parties Ad hoc group DK, DE, NL, UK Complete revision by end June Ad hoc group makes decision by end July Proposal for new international experiment (but no funding yet) 2

AARHUS UNIVERSITY Methodologies based on few data Ammonia emissions from crops and crop residues NO emissions from soils Keep methodology in the Guidebook Need to make clear in Guidebook that these emission estimates are uncertain 3

AARHUS UNIVERSITY Emissions from biogas Need to maintain the N flow principle for ammonia and NO Link 3B, 5B2 and 3D Ad hoc group AT(?), NL, DE, DK, UK Can use DE methodology as a basis First draft by end of June Ad hoc group makes decision by end July 4

AARHUS UNIVERSITY Task Force on Reactive Nitrogen Paris 9-11April Joint meeting with OECD Focus on role of animal production on N pollution Debate driven by health considerations Role of ammonia in formation of secondary PM emissions Expert Panel on Mitigation of Agricultural Nitrogen Aim ‘living’ document describing N and ammonia abatment measures Expert Panel on Nitrogen Budgets Guidance on constructing national nitrogen budgets Expert Panel on Nitrogen and Food Focus on inefficiencies in food production/consumption (‘farm to fork’) 5

AARHUS UNIVERSITY Workplan  Complete new methodologies for fertiliser NH 3 emission  Complete guidance on reporting emissions from anaerobic digestion  Continue and intensify the collaboration with TFRN  Discuss with modelling community:  Crop NH 3 emissions, NMVOC emissions, soil NOx emissions  Assess need for methodologies for marine NH 3 emissions and indirect NO emissions.  Liaise with IPCC revision of agricultural sector.
