Available at: http://cait.wri.org." Technical Notes "Adapted from R.A. Houghton's Data Note: Emissions (and Sinks) of Carbon from Land-Use Change" "" "Definition:" "CO2 Emissions by Source: Cumulative emissions from land use change measures the total mass of carbon dioxide (CO2) absorbed or emitted into the atmosphere between 1950 and 2000 as a result of man-made land use changes (e.g., deforestation, shifting cultivation, vegetation re-growth on abandoned croplands and pastures). Positive values indicate a positive net flux (""source"") of CO2; for these countries, carbon dioxide has been released into the atmosphere as a result of land use change. Negative values indicate a negative net flux (""sink"") of CO2; in these countries, carbon has been absorbed as a result of the re-growth of previously removed vegetation." "" "While the majority of global CO2 emissions are from the burning of fossil fuels, roughly a quarter of the carbon entering the atmosphere is from land use change. Together, CO2 from fossil fuels and cement manufacture, CO2 from land-use changes, and the emissions of five non-CO2 gases--methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6)--constitute the main sources contributing to climate change." "" "Data presented here include emissions from living and dead vegetation disturbed at the time of clearing or harvest, emissions from wood products (including fuelwood), and emissions from the oxidation of soil organic matter in the years following initial cultivation. Those ecosystems that are not directly affected by human activities such as agriculture and forestry are not included in these estimated sources and sinks. " "" "Data are presented in thousand metric tons of CO2. Values were converted to CO2 equivalent values from original values showing the mass of elemental carbon; WRI multiplied the original carbon mass by 3.66419 (the ratio of the molecular mass of CO2 to that of carbon)." "" "Years Covered and Frequency of Update:" "Cumulative emissions from 1950 to 2000 were calculated by WRI based on annual data provided by R.A. Houghton at the Woods Hole Research Center in Woods Hole, MA. While a number of regional and global estimates have been calculated of carbon flux from land-use change, this is the first global data set with country-level data." "" "Methodology:" "The net flux of CO2 was calculated on a global and regional level by Houghton et al. Regional fluxes (changes in above- and below-ground carbon) were modeled based on annual rates of wood harvest and changes in agricultural area. " "" "Once regional fluxes were calculated, they were divided among countries. For tropical regions, each flux was distributed among countries in proportion to the product of change in forest area (1990-2000) and average forest biomass as reported by the FAO’s Forest Resources Assessment 2000 (see http://www.fao.org/docrep/004/y1997e/y1997e00.htm). For regions outside the tropics, the flux was divided among countries in proportion to annual rates of wood production (harvest) as reported by FAOSTAT (see http://apps.fao.org). The only exception to this method was for European countries between 1975 and 2000. For this interval, the regional sink was distributed among countries by the 1990-2000 change in forest area (similar to the approach for tropical regions). Three of the “regions” (Canada, the United States, and China) provided national estimates directly. " "" "WRI calculated cumulative carbon emissions from land use change from the annual country-level data. " "" "Data Reliability:" "Please note that values presented here are estimates. For many countries, cumulative sums do not represent all years between 1950 and 2000 (data are not available for all years during this time period). For details about which years are utilized in a particular country's sum, please consult the original dataset of CO2 emissions due to land use change, available on the CAIT website." "" "These data provide a very rough picture of the level of carbon entering the atmosphere from land-use change and should be treated as order-of-magnitude estimates. Houghton states that yearly flux estimates are uncertain on the order of ±150% for large fluxes, and ±50 million tons of carbon per year for estimates near zero. The cumulative emissions presented here, however, are more accurate than the data for each year. " "" "The estimates do not explicitly include changes in carbon stocks that may result from various forms of management such as agricultural intensification, fertilization, no-till agriculture, thinning of forests, changes in species or varieties, and other silvicultural practices. Furthermore, the analysis ignores fluxes of carbon to or from ecosystems not directly affected by land-use change.
