|Abstract:||We present a pan-European irrigation map based on regional European statistics, a European land-use map and a global irrigation map. The map provides spatial information on the distribution of irrigated areas per crop type which allows determining irrigated areas at the level of spatial modelling units. The map is a requirement for a European scale assessment of the impacts of irrigated agriculture on water resources based on spatially distributed modelling of crop growth and water balance. The irrigation map was compiled in a two step procedure. First, irrigated areas were distributed to potentially irrigated crops at a regional level (European statistical regions NUTS 3), combining Farm Structure Survey (FSS) data on irrigated area and crop-specific irrigated area for selected crops and total crop areas. Second, crop specific irrigated area was distributed within each statistical region based on the crop distribution given in our land use map. A global map of irrigated areas with a 5¿ resolution was used to further constrain the distribution within each NUTS3 based on the density of irrigated areas. The constrained distribution of irrigated areas as taken from statistics to a high resolution data set enables us to estimate irrigated areas for various spatial entities, including administrative, natural and artificial units, providing a reasonable input scenario for large scale distributed modelling applications. The data set bridges a gap between global data sets and detailed regional data on the distribution of irrigated areas and provides information for various assessments and modelling applications.|
