Aims UNECE TFEIP Agriculture and Nature Panel


Expert Panels

• Panels are ad hoc.

• Currently four panels:– Combustion and Industry.– Transport.– Agriculture and Nature.– Review.

• Main job – Emission Inventory Guidebook.


Emission Inventory Guidebook

• Encourage accurate reporting of emissions.– Guidebook not Rulebook.

• General and specific guidance.

• Chapter 10 – Agriculture

• Methodology.– Simple – only for minor sources.– Detailed.


Chapter 10 - AgricultureNot included:• All forest emissions.• Natural grassland and similar ecosystems.• Non- agricultural soils.• Wetlands.• Open waters (lakes, ponds, rivers etc).• Wild animals.• Humans.• Lightning.• Volcanoes.• Gas seeps.


Chapter 10

• 10 01 Cultures with Fertilizers.– NH3, N2O and NO from crops and the

application of mineral fertilizers.

– N2O from histosols.

– Mark Theobald, Centre for Ecology and Hydrology, Edinburgh, UK


Chapter 10 (cont)

• 10 02 Cultures without Fertilizers.– Emissions of NH3 from legumes and grazed

grassland.

– Emissions of N2O from N inputs to soils other than fertilizer (crop residues, grazing, atmospheric deposition, leaching).

– No changes.


Chapter 10 (cont)

• 10 03 Stubble Burning (NH3 and NH4).

– No changes

• 10 04 Enteric Fermentation (CH4).

– No changes


Chapter 10 (cont)

• 10 05 Manure Management (C species).– CH4.

– non-methane volatile organic compounds.– Jim Webb, ADAS, Wolverhampton, UK.

• 10 06 Pesticides and Limestone (CO2).

– No change.


Chapter 10 (cont)

• 10 09 Manure Management (N species).– NH3 from grazing, animal housing, storage and

spreading of slurry and solid manure.

– N2O, NO and N2 from manure management.

– Ulrich Dämmgen, Federal Agricultural Research Centre, Braunschweig, Germany


Chapter 10 (cont)

• 10 XX Particulate matter (PMs).– Arable farming.

• Torsten Hinz, Germany

– livestock farming• No developments.


2005 issues revisited

• Omissions– Particulate matter (PM) emissions.

• Updating– Latest scientific developments.

– S & E Europe.

• Not user-friendly.– Too much detailed science.

– Too little detailed guidance.


New issues

• Co-ordination with IPCC Guidelines– Need for consistency.– Avoidance of duplication.


Strategy

• User friendliness.– Step-by-step methodology.– Put detailed science in Appendices..

• Omissions/updating.– Rectify as and when resources permit.

• Co-ordinate with IPCC Guidelines– use IPCC methods for main greenhouse gasses
