# IPCC 2006 AFOLU The document **"2006 IPCC Guidelines for National Greenhouse Gas Inventories"**, in particular **Volume 4: Agriculture, Forestry and Other Land Use (AFOLU)**, has the primary purpose of **providing guidelines for the preparation of annual greenhouse gas (GHG) inventories in the AFOLU sector**. This document integrates and updates the previous 1996 IPCC guidelines, which separately addressed agriculture and land use change and forestry. The integration was made recognising that the processes underlying GHG emissions and removals, as well as the various forms of terrestrial carbon stock, can occur in all types of land and that land use changes can involve all types of land. The key objectives and features of the 2006 IPCC Guidelines include: * **Improving consistency and completeness**: The integrated approach aims to improve consistency and completeness in the estimation and reporting of GHG emissions and removals. * **Supporting national reporting**: Designed to assist countries in estimating and reporting national inventories of anthropogenic GHG emissions and removals. For the AFOLU sector, these are defined as all those occurring on "managed land", i.e. land on which human interventions and practices have been applied to fulfil productive, ecological or social functions. * **Adoption of land use categories**: Adopts the six land use categories used in the Good Practice Guidance for Land Use, Land-Use Change and Forestry (GPG-LULUCF): Forest Land, Cropland, Grassland, Wetlands, Settlements and Other Land. These categories are further subdivided into land remaining in the same category and land converted from one category to another, and are designed to include all managed land area within a country. * **Inclusion of non-CO2 emissions**: Incorporates methods for non-CO2 emissions from managed soils and biomass burning, as well as characterisation of livestock populations and manure management systems. * **Tiered hierarchical structure**: Adopts three hierarchical levels of methods (Tier 1, 2, 3) ranging from default emission factors and simple equations to the use of country-specific data and models, to adapt to national circumstances. * **Key category analysis**: Incorporates key category analysis to identify the sources/sinks of greatest influence on a country's total inventory, helping to prioritise resource use for a more reliable inventory. * **Mass balance principles**: Adopts mass balance principles in the calculation of carbon stock changes. * **Improvements in emission factors**: Offers improvements to default emission and stock change factors, as well as the development of an Emission Factor Database (EFDB) as a supplementary tool. {% embed url="" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
