Water intensity of crop production in Europe, 2007-2016

• Total water input is expressed in m3/ha and gross value added is expressed in purchasing power standard (PPS)/ha, where the area in ha represents the sum of arable land and land with permanent crops. The monetary unit being used (PPS) accounts for purchasing power differences among countries. Theoretically, one PPS can buy the same amount of goods and services in each country.
• Water use intensity of crop production is classified at the regional level according to the quartile (Q) distribution of all time series (2005-2016): below Q1 (light blue) indicates a low water intensity of crop production; above Q3 (dark blue) indicates a high water intensity of crop production; and between Q1 and Q3 (mid-blue) indicates a moderate water intensity of crop production.
• Regional groupings of EU Member States and the UK are based on UN Geoscheme — Standard M49: eastern Europe (Bulgaria, Czechia, Hungary, Poland, Romania and Slovakia), northern Europe (Denmark, Estonia, Finland, Ireland, Lithuania, Latvia, Sweden and the United Kingdom), southern Europe (Cyprus, Greece, Croatia, Italy, Malta, Portugal, Slovenia and Spain) and western Europe (Austria, Belgium, Germany, France, Luxembourg and the Netherlands).
• Gap filling has been performed for certain years and countries: 2010 data have been used for 2011 Greece data; 2006 data have been used for 2007 Hungary data; 2005 data have been used for 2007 Luxembourg data; 2009 data have been used for 2010 Portugal data; 2015 data have been used for 2016 Sweden data.
