GHG Inventory - 2006 AFOLU : Agriculture, Forests and Other Land Use Lessons from 1996 GL • GHG emissions/removals from all land categories & conversions not addressed, methods not given • All carbon pools not included in default methods • Non-CO2 gas emissions from Savanna burning presented in Chapter 4 (Agriculture), but Savanna considered in Chapter 5 (Forests) • Lack of synergy between N2O loss sections (Agriculture) and CO2 loss sections (LUCF) in soils - N2O from soil; in agriculture - CO2 from soil; in LUCF • Absence of linking biomass and soil carbon Key-problems faced by parties using revised IPCC – 1996 GL • IPCC – GL classification of forests and other land categories not compatible with national system of classification • Lack of clarity on ‘managed forest’, ‘managed natural forest’ and ‘natural forest’ • Limited guidance on uncertainty • Absence of methods for CH4 from agricultural soils, below ground biomass etc. GPG 2000, GPG 2003 addressed some of these issues Limitations of GPG 2003 • Lack of clarity on managed and unmanaged land • Methods/approaches need to be made more userfriendly • Description of methods diffused across different chapters/sectors • Inadequate guidance for Tier-3 methods • Inconsistency in treatment of DOM • Emissions from burning of Savannas; agriculture or forest or grassland • Level of disaggregation for different land categories and livestock categories AFOLU – key features • Merging of Agriculture, Forest &other Land uses and Livestock systems • Adoption of GPG 2003 approach - all land categories in an integrated way - inclusion of livestock and manure arrangement - inclusion of all C-pools and relevant non-CO2 gases in default approach • Incorporation of key source category analysis - land use categories - C-pools and non-CO2 gases AFOLU – key features • Adoption of 3-tier methods - Tier-1; default methods and data - Tier-2; simple equations and country specific data - Tier-3; models and inventory programs • Improved default data and use of EFDB • Improved guidance for T-2 and T-3 • Improved treatment of uncertainties • Common methodology chapter • Volume-1; Cross cutting issues • Reporting Tables & Worksheets (for default methods) Status/progress • Chapter outline approved and being used for different sections • Zero-order draft of different sections nearly ready • ISSUES: 1. uncertainty estimates; limited data 2. treatment of HWP 3. treatment of DOM 4. C-stock transfers; biomass, DOM, SOC 5. limited default data for many EF/RF 6. adoption of land use/management systems compatible to default data and national system of classification 7. Mapping back of GHG estimates between 2006 GL and 1996 GL AFOLU – Approved Table of Contents • Overview and cross-cutting issues • Consistent representation of lands/management systems • Summary of the methodologies (and general equations for pools & gases) • Agriculture - Cropland - Grassland - Livestock • Forest lands - forest land remaining forest land - land converted to forest land • Wetlands - peat lands - flooded lands • Settlements • Other land categories • Other - HWP (taking into consideration any decision of the COP on this matter) Steps adopted for 2006 GL 1.Select all land categories and management systems (livestock & manure) relevant to the country (based on Chapter 4.2) 2.Conduct key source/sink category analysis - land categories, livestock management systems - carbon pools - non-CO2 pools 3. Select appropriate Tier level based on - key-category analysis - resources/national circumstances 4. Select the method of estimation (equations) based on Tier selected Steps adopted for 2006 GL 5. Assemble activity data and emission factors and estimate GHG emissions/removal 6. Estimate uncertainty 7. Adopt QA and QC procedures 8. Report GHG emissions/removal using the reporting tables 9. Document and archive all information
