GHG Inventory - 2006 AFOLU Agriculture, Forests and Other Land Use
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
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
Chapter 1 Introduction Chapter 2 Consistent Representation of Lands/Management Systems Chapter 3 Overview of Generic Methodologies for Pools and Fluxes Chapter 4;Agriculture Cropland, Grassland Livestock Chapter 5 Forest land Chapter 6 Wetlands Chapter 7 Settlements Chapter 8 Other land Chapter 9 Harvested Wood Products Annex A Worksheets AFOLU Volume Outline(IPCC Approved)
Improvement in Default Emission Factors • Additional emission factors given for different C-pools and non CO2 gases at disaggregated level • Attempt to link inventory process with EFDB • Attempt to provide and improve the uncertainty estimates for the EF and AD
Limitations or outstanding issues? • User-friendliness?? How to improve? • Implications for data-poor and resource-poor 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
