Economic growth and individual wealth are shifting diets from predominantly starch-based to meat and dairy, which require more water.

Sep 24, 2015

Producing 1 kg of rice, for example, requires ~3,500 L of water, 1 kg of beef ~15,000 L, and a cup of coffee ~140 L (Hoekstra and Chapagain, 2008). This dietary shift is the greatest to impact on water consumption over the past 30 years, and is likely to continue well into the middle of the twenty-first century (UN Food and Agriculture Organization, 2006).
