The Water Footprint of Food Guide helps people understand the large amount of water required to grow and produce food. This methodology provides the data, calculations and sources used to create the values in the Guide.
How The Water Footprint of Food Guide Was Created
The Water Footprint of Food Guide is an interactive web app that gives people an idea of all the water required to produce the food they eat every day. The Guide contains more than 100 common foods and beverages typical of the American diet, and for each item provides a total water footprint, a breakdown of water footprint components, and context about water used in production. This online tool was created for educational purposes and is intended for use by teachers, students, researchers, and the media, among others.
