GHG Inventory - 2006
AFOLU
Agriculture, Forests
and Other Land Use
Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC
AFOLU – Key Features
1. New approach to inventory from land use and livestock system
2. Merging of Agriculture, Forest & Other Land uses
Lack of clarity on agro-forestry and urban forestry in 1996 GL
Linking of Biomass and SOC for different land use categories in 2006 GL
Confusion in estimation/reporting of CO2 and N2O – between Agri. & LUCF
in 1996 GL
Addressing emissions from fire from different land categories in 2006 GL
3. Wetland incorporated into the volume as a land use category
4. Settlements and other land categories included in estimation and
reporting structure
5. HWP incorporated in to volume & in Reporting Tables :
6. Adoption of GPG 2003 approach for IPCC 2006
- all land categories in a consistent way;
- inclusion of five C-pools and relevant non-CO2 gases in default approach
- Incorporation of key source category analysis
- land use categories & sub-categories
- C-pools and non-CO2 gases
Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC
Key Features…
Estimating GHG inventory for all managed land categories
To account for emissions and removal for all land categories
To achieve consistency over the years; Area and GHG estimates
To avoid exclusion or double counting
Livestock and Manure management integrated in to Agric.
chapter
Improved default data and use of EFDB
Improved guidance for T-2 and T-3
Improved treatment of uncertainties
Common generic Methodology Chapter
Volume-1; Cross cutting issues
Reporting Tables & Worksheets (for default methods)

Consistent Representation of Lands/Management
Systems
6 land categories: forest land, cropland, grassland,
wetlands, settlements and other land
Land (FL) remaining in same category (FL) – default 20 yrs
Land (Other) converted to that category (FL)
Origin of land converted – sub-divide
Cropland (CL) to forest (FL); grassland (GL) to forest (FL)
Further categorization of each land category
desirable
Climate (boreal, temperate, tropical forests)
Soil type (clay, sandy etc.)
Ecological (Evergreen, deciduous, desert etc.)
Management (Managed forest / plantations, Improved
grassland, unimproved grassland, tillage intensity, irrigation,
manuring)
Land use categories: Types 1, 2 & 3
Matching land areas with EF availability

Attempt to link inventory process with
EFDB
Attempt to provide and improve the
uncertainty estimates for the EF and
AD
Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC
Limitations or outstanding issues?
User-friendliness?? How to improve?
Implications for data-poor and resourcepoor countries ?
Emissions / Sequestration factors needed
for a large number of Activity Data
Improving the EFDB
Treatment of HWP?
Transfer of Carbon among pools; AGB,
Dead wood, litter, SOC
Matching land categories and EF/RF
Limited information on uncertainties; EF, AD
