GHG Inventory - 2006

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) Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC 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  Land use categories: Types 1, 2 & 3  Matching land areas with EF availability Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC 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) AFOLU Volume Outline (IPCC Approved)  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 Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC Summary Table – AFOLU GHGs Sources and Sinks 3.

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 Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC
