Taka Hiraishi, IPCC Task Force on National Greenhouse Gas Inventories, introduced the IPCC Good Practice Guidance (GPG) for Land Use, Land-Use Change and Forestry (LULUCF), and Definitions and Methodological Options to Inventory Emissions from Direct Human-Induced Degradation of Forests and Devegetation of Other Vegetation Types. Several authors of the GPG for LULUCF then presented the report's various chapters.
Jim Penman, UK Department for the Environment, Food and Rural Affairs, presented a general overview of the IPCC GPG for LULUCF report. He explained that the GPG contains advice on implementing the Revised 1996 IPCC Guidelines on National Greenhouse Gas Inventories, including advice on estimation methods, quality assurance and control in the application of methods, documentation, archiving, and estimating uncertainties.
Presenting the chapter that addresses the basis for consistent representation of land areas, Ronnie Milne, Natural Environment Research Council, stressed the need for methods that are adequate, consistent, complete and transparent. Noting the need for “land categories” that are mappable by remote sensing and provide a robust basis for carbon estimation, he identified six categories: forest lands; croplands; grasslands; wetlands; settlements; and other.
Milne outlined three approaches for categorizing land: basic land-use data; survey of land use and land-use change; and geographically explicit land use.
N.H. Ravindranath, Indian Institute of Science, presented the report's chapter that covers the Land-Use Change and Forestry (LUCF) Sector GPG. He drew attention to significant advances over the 1996 IPCC Guidelines, including adoption of the land use category approach to organize methodologies and GPG, and the introduction of three hierarchical tiers of methods for land use categories, gases and carbon pools.
Bernhard Schlamadinger, Joanneum Research, discussed the report's section on supplementary methods and GPG arising from the Kyoto Protocol. He outlined steps for estimating and reporting supplementary information, and presented decision trees for classifying lands and for determining whether a unit of land is subject to direct human-induced deforestation.
Sandra Brown, Winrock International, described the section concerning LULUCF projects, noting that it provides, inter alia: guidance on measuring, monitoring and estimating anthropogenic changes in carbon stocks and greenhouse gas emissions and removals resulting from LULUCF activities at the project level; guidance for multi-tier, practical steps for designing and implementing measures and monitoring plans and for estimating changes in carbon stocks and non-CO2 greenhouse gases; and “stand alone” guidance with cross linkages to other sections of the report.
Newton Paciornik, Ministry of Science and Technology of Brazil, outlined the chapter that addresses cross-cutting issues such as identifying and quantifying uncertainties, sampling, identifying key categories, and ensuring quality assurance and control, time series consistency and recalculations, and verification.
Samuel Kainja, Forestry Department of Malawi, presented the report on Definitions and Methodological Options to Inventory Emissions from Direct Human-Induced Degradation of Forests and Devegetation of Other Vegetation Types. He said the report addresses definitions, methods for inventory, scale and effect, and unbalanced accounting.
