The average water footprint of food consumption (dietary patterns) in the EU is estimated at 5,730 litres/capita/day (Vanham et al., 2013). However, the average water footprint per capita in the Mediterranean (3,280-5,790 litres/capita/day) (Vanham et al., 2016) is much higher than in Scandinavia (2,940-3,550 litres/capita/day) (Vanham et al., 2017), which is partly explained by differences in bio-climatic conditions and composition of food consumption. For example, Mediterranean people have moved away from past dietary patterns, increasing their consumption of meat, dairy and processed food in the past decades. However, these products require proportionately more water than most crops for their production (Mekonnen and Hoekstra, 2012, 2011).
