This document discusses the development of the 2006 IPCC Guidelines for National Greenhouse Gas Inventories for the Agriculture, Forestry and Other Land Use (AFOLU) sector. It identifies limitations in previous guidelines, including a lack of comprehensive methods and data. The key features of the 2006 AFOLU guidance are outlined, including a merged approach for agriculture, forests and lands; adoption of a three-tiered method; and improved default data and guidance. Progress on developing the 2006 AFOLU chapters is discussed, along with some remaining issues to address.

1. GHG Inventory - 2006
AFOLU :
Agriculture, Forests and
Other Land Use

2. 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

3. 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

4. Limitations of GPG 2003
• Lack of clarity on managed and unmanaged land
• Methods/approaches need to be made more user-
friendly
• 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

5. 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

6. 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)

7. 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

8. 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)

9. 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

10. 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
