FAOSTAT GHG Emissions from Organic Soils
收藏资源简介：
The FAOSTAT domain “Cultivation of Organic soils” contains estimates of nitrous oxide (N<sub>2</sub>O) emissions associated with the drainage of organic soils <em>–</em> using <em>histosols </em>as proxy <em>–</em> for agriculture. Data are computed geospatially, using the Tier 1 default factors of the Intergovernmental Panel on Climate Change (IPCC, 2006). Estimates are available by country, by FAOSTAT regional aggregation and special group, including the Annex I and Non-Annex I Parties to the United Nations Framework Convention on Climate Change (UNFCCC), and with global coverage for the period 1990–2019, with estimates for 2030 and 2050. The FAOSTAT domain “Cultivation of Organic soils” disseminates N<sub>2</sub>O emissions, implied emission factors and underlying activity data, i.e. area (in ha) of organic soils drained for agriculture. Drainage and associated emissions are assessed separately for IPCC land use categories cropland and grassland, corresponding to FAO land use categories ‘’cropland’’ and ‘’permanent meadows and pastures.’’ GHG estimates are available in N<sub>2</sub>O and in CO<sub>2</sub> equivalent (CO<sub>2</sub>eq). Conversion to CO<sub>2</sub>eq is made via Global Warming Potentials (GWP) coefficients. Results are disseminated separately for three different options currently in use in reporting, namely GWPs from: <em>a)</em> IPCC Second Assessment Report (SAR)(IPCC, 1996); <em>b)</em> IPCC Fourth Assessment Report (AR4) (IPCC, 2007); and <em>c)</em> IPCC Fifth Assessment Report (AR5)(IPCC, 2014). The original FAOSTAT domains can be found here: Cultivation of Organic Soils: http://www.fao.org/faostat/en/#data/GV Drained Organic Soils on cropland: http://www.fao.org/faostat/en/#data/GC and Drained Organic Soils on grassland: http://www.fao.org/faostat/en/#data/GG The FAOSTAT emissions estimates may not coincide with GHG data reported by member countries to relevant international reporting processes. The aim of this domain is to provide a global reference database for assessing regional and global trends and in support of national data quality/data assurance processes.
