This dataset is developed in the framework of the AQUASTAT - programme of the Land and Water Development Division of the Food and Agriculture Organization of the United Nations and the Johann Wolfgang Goethe Universität, Frankfurt am Main, Germany. The map shows the amount of area equiped for irrigation at the end of the 20th century as a percentage of the total area on a raster with a resolution of 5 minutes. The area actually irrigated was smaller, but is unknown for most countries. A special note has to be made for Australia where the map shows the total area actually irrigated. This is due to the fact that statistics collected in Australia refer to actually irrigated area as opposed to statistics with area equiped for irrigation which are collected in most other countries. Due to the map generation method, the quality of the map can never be uniform. The overall quality of the map depends heavily on the individual quality of the data for the different countries. This dataset is generally used in GIS-based water balance model calculations to assess water use by irrigated agriculture. 5020.png large_thumbnail 5020_s.gif thumbnail gif irrigation irrigated areas irrigated agriculture hydrology AQUASTAT AQUAMAPS_infrastructure World eng farming 1990 2000 -180 180 -90 90 The map is generated as a grid with a cellsize of 5 arc minutes. For the GIS-users the map is distributed in two different formats: as a zipped ASCII-grid that can be easily imported in most GIS-software that support rasters or grids; and, to accomodate people who use GIS-software that doesn't support rasters or grids, as a zipped ESRI shape file. The non-GIS-users can download the map as PDF-file in two different resolutions. Users are requested to refer to the map as follows: "Stefan Siebert, Petra Döll, Sebastian Feick, Jippe Hoogeveen and Karen Frenken (2007) Global Map of Irrigation Areas version 4.0.1.
