Presentation Transcript

  1. Agriculture, Forestry and Other Land-Use: Combining two sectors of the IPCC 1996 Guidelines Leandro Buendia Technical Support Unit – IPCC NGGIP

  2. Outline • Introduction of the 2 Sectors • Challenges to Integration • Approach to Integration • Progress so far…

  3. Bases for 2006 Guidelines • Revised 1996 IPCC Guidelines (1996GL) • GPG2000 • GPG for LULUCF • Plus: • Experience in the use of GLs and GPGs • New scientific and technological development

  4. Agriculture Sector in 1996GL and GPG2000 • CH4 Emissions from Enteric Fermentation • CH4 and N2O Emissions from Manure Management • CH4 Emissions from Rice Cultivation • GHG Emissions from Savanna and Agricultural Burning • N2O Emissions from Agricultural Soils

  5. LUCF Sector in 1996GL • Changes in Forest and Other Woody Biomass Stocks • Forest and Grassland Conversion • Abandonment of Managed Lands • CO2 Emissions and Removals from Soils • Other

  6. LULUCF-GPG • Forest Land • Cropland • Grassland • Wetlands • Settlements • Other Land

  7. Challenge to Integration… 1996GL (3 Vols.) GPG2000 2006GL LULUCF- GPG • new development • experience

  8. Challenges to Integration • Present the methodological guidance in a more step-by-step “cookbook” structure; • Avoid repetition of information among the 1996GL, GPG2000, and LULUCF-GPG; • Avoid double counting or omissions and to be consistent with the treatment of categories (e.g. N2O from soils, GHG from biomass burning, etc.) • Provide default values for all Tier 1 variables wherever possible; • Re-evaluate and improve the current default emission factors.

  9. Approach to Integration • to be based on the IPCC approved TOC • to merge the materials from the 1996Guidelines, GPG2000 and GPG-LULUCF; • to use the structure consistent with the GPG-LULUCF (i.e. by land-use category); • to integrate Agriculture into this new framework to resolve inconsistencies and avoid double counting; • to be consistent with existing inventory data; • to update data, methods and emission factors where feasible.

  10. Progress so far…

  11. Volume 4: Agriculture, Forestry and Other Land Use (AFOLU) 4.1 Overview and cross-cutting issues 4.2 Consistent Representation of Lands 4.3 Agriculture - Cropland and Grassland Remaining Cropland and Grassland - Land Converted to Cropland - Land Converted to Grassland - Livestock 4.4 Forest lands - Forest land remaining forest land - Land converted to forest land 4.5 Wetlands - Peatlands - Flooded lands 4.6 Settlements - Settlements remaining settlements - Land converted to settlements 4.7 Other land 4.8 Other - HWP (taking into consideration any decision of the COP on this matter)

  12. 69 Experts/Authors for AFOLU(3 CLAs; 66 LAs) Biomass (23) Livestock (9) Representation (4) Soils (17) Wetlands (11) HWP(5)

  13. CLAs Meeting b/b with Cross-Cutting Issue Meeting, Oslo (May 2004) Elaborated the TOC … 4.1 Overview and cross-cutting issues 4.2 Consistent Representation of Lands/ManagementSystems 4.3 Summary of the Methodologies (equations for pools and gases) 4.4 Agriculture 4.5 Forest lands 4.6 Wetlands 4.7 Settlements 4.8 Other land 4.9 Other

  14. 4.4 Agriculture 4.4.1 Cropland and Grassland Remaining Cropland and Grassland 4.4.2 Land Converted to Cropland 4.4.3 Land Converted to Grassland 4.4.4 Livestock

  15. 4.4.1 Cropland Remaining Cropland • Choice of Method • Choice of E/R Factor • Choice of Activity Data 4.4.1.1 Biomass (above- and belowground biomass) - Change in carbon stocks in - Methodological Issues - Uncertainty Assessment 4.4.1.2 Dead organic Matter (litter and deadwood) - Change in carbon stocks 4.4.1.3 Soils - Change in carbon stocks (mineral, organic, liming) - CH4 from rice cultivation - Direct N2O from soils - Indirect N2O from soils 4.4.1.4 Non-CO2 GHG emissions (CO, CH4, N2O, NOx) - burning of biomass/residues

  16. …and similar elaboration was applied to other sections 4.4 Agriculture - Cropland and Grassland Remaining Cropland and Grassland - Land Converted to Cropland - Land Converted to Grassland - Livestock 4.5 Forest lands - Forest land remaining forest land - Land converted to forest land 4.6 Wetlands - Peatlands - Flooded lands 4.7 Settlements - Settlements remaining settlements - Land converted to settlements 4.8 Other land 4.9 Other

  17. AFOLU Authors/Expert Meeting, Mauritius (June 2004) • General Guidance to Authors of the 2006GL (Oslo output) • to guide authors in writing contributions to the 2006GL • to ensure a consistent and coherent approach across all the volumes and to promote common terms used

  18. Some major decisions in Mauritius • to have a generalized framework to describe C stock changes, disturbance impact and non-CO2 emissions for consistent treatment of C stock and transfers among biomass, DOM and soil • to develop consistent terminology and symbols for pools and transfers • to check GPG equations for consistent use of terminology and completeness • to review additional literatures on EF readjust some default EFs, scaling factors • to provide guidelines on using additional activity data (water management, organic amendments, climate zone, soil type)

  19. Some major decisions in Mauritius • to provide uncertainty levels for default EFs and other default parameters • to provide QA/QC methodology to ensure completeness of reported emission related to N sources • to review and revise decision trees to reflect all available options • to do proper accounting for applied nitrogen to soils from manure management systems

  20. Some major decisions in Mauritius • to enhance consistency in representation of land areas using a common set of classifications of land into areas that match default factors and where possible available global data • to provide guidance on matching area estimates to default factors in the methodological guidance • to encourage transparent reporting through (or to) classification systems, relevant at Tiers 2 and 3 HWP group did not meet (to take into consideration any decision of the COP on this matter); to meet in November 2004

  21. Workplan for First-order Draft Mauritius – identified tasks and assignments June-Oct 15 – Work by LAs & CLAs to draft report Oct 15-Nov 15 – Consolidation/exchange of draft Nov 15-Dec 1 – Drafts finalized by CLAs November –incorporation of HWP section Dec 1 – 0+ draft to TSU - tech. editing/formatting Jan 05 – Consolidation meeting for 1o draft Mar 05 – Final 1o draft for expert review
