摘要

The aim of the paper is to present the methodology, main results, problems and difficulties in the national greenhouse gas inventory process for the LULUCF sector in Bulgaria. This sector includes emissions and greenhouse gas removals from different land-use categories, changes in the land-use and forestry. The inventory in this sector was based on representative top level land-use categories under IPCC GPG (2003) - Forest land, Cropland, Grassland, Wetland, Settlements, Other land, as well as land-use changes. The inventory methodology for the greenhouse gases followed the principles envisaged in the IPCC GPG for LULUCF (2003). All the land-use changes were traced down and reported for a transition period of 20 years after which they were reported in the respective categories. To achieve the full time series of 1988-2008 period for the areas staying in a certain land-use category and the land-use changes, data from different statistical sources were used (National Statistical Year Book, Forestry Fund Reports, Agrostatistics, Cadastral maps, etc.). Major problem was the limited information on the changes and the conversion between the separate categories. When data for completing the information were missing, information from available statistics were used as well as probability assumptions on land-use changes and estimates to level off the occurring land area changes were carried out. The uncertainty assessment was another complicated issue that has to be solved in the near future. The results from the inventory of the greenhouse gas emissions/ removals showed that the LULUCF sector was serving as a sink of greenhouse gases for Bulgaria. An important category was 'Forest Land' and especially 'Forest Land Remaining Forest Land'. The two categories 'Forest Land' and 'Grassland' were removals of CO_2 .All other categories were sources of emissions of CO_2 and the total amount of emissions from these categories was between 7.7-17.7% from the removals of CO_2 from Forest Land and Grassland.
