    "additionalInfo": "Land use indicates the socioeconomic use of land (for example, agriculture, forestry, recreation or residential use). In particular it defines a number of services such as agriculture, forestry, industry, transport, housing and other services  that use land as a natural and/or an economic resource. Land use has to be distinguished from Land Cover  which refers instead to to the bio-physical coverage of land (for example, crops, grass, broad-leaved forest, or built-up area). The FAOSTAT Land Use domain includes categories of land primarily focusing on their use for agricultural and forestry activities. Definitions of these items (land categories) are available at: http://http://www.fao.org/faostat/en/#data/RL. These definitons are compliant with those included in the SEEA AFF, the SEEA CF and the Framework for the Development of Environmental Statistics (FDES 2013)",

    "dataPublisherSource": "Primary sources of data is the FAO Land Use, Irrigation and Agricultural Practices questionnaires. Official information may be complemented with statistics from national statistical yearbooks and other official publications and information from governmental data portals. Supplemental information may be derived from national and international sectoral studies and reports.  Forest land data The Global Forest Resource Assessment (FRA) is the supplementary source of Forest land data disseminated in FAOSTAT. FRA data cover 1990, 2000, 2005, 2010 and 2015. Gap filling for deriving a complete time series 1990\u20132015 was performed as follows. Intermediate years were estimated using linear interpolation performed by the FAO Statistics Division. Missing data at the beginning or at the end of the time series were imputed by maintaining the value of the nearest FRA data. FRA data on Carbon density and area were first imputed in the same manner described above for deriving a complete time series 1990\u20132015, and then multiplied (stock density times area) to obtain carbon stock. Regional average values of carbon density were used in case of missing national data. Data for the element \u201cCarbon stock in living biomass\u201d are available only for the item \u201cForest land\u201d. Data for the element \u201cArea\u201d are available for the item \u201cForest land\u201d, \u201cForestry\u201d and for the three subcategory items \u201cPlanted forest\u201d, \u201cPrimary forest\u201d and \u201cOther naturally regenerated forest\u201d. 2016 Forest land data (for both elements, \u201cArea\u201d and \u201cCarbon stock in living biomass\u201d) were calculated by linear extrapolation of the data range 2010-2015. Irrigated land Data on \u201cLand area equipped for irrigation\u201d disseminated through FAO's global water information system (AQUASTAT) and FAOSTAT are regularly reconciled for coherency. Organic agriculture Data from the Research Institute of Organic Agriculture (FiBL) are used on a regular basis as secondary sources to complement primary data on \u201cArea certified organic\u201d and \u201cArea in conversion to certified organic\u201d items."
