Abstract

Global food demand is increasing and changing rapidly as a result of multiple drivers as population growth or urban dietary shifts. Managing food consumption (people’s eating habits) might deliver important co-benefits from a water perspective. Many recent studies have addressed the relationship between diet habits and associated water impacts. The goal of this study is to assess and compare the water footprint (WF) of two recommended diets (Mediterranean and American) in Spain and US. Moreover also focuses on assessing the WF of the food consumption and its associated food waste in Spanish households during one year. Our results show that the American diet has a 29% higher WF, regardless of products' origin. Food consumption and waste WFs in Spain are 3,302 and 131 litres/person day respectively. A shift back to a Mediterranean diet, in which fruits, fish and vegetables account for a larger share of the food intake, would deliver great water savings.
