Weekend reading: the food system and water use

I am happy to see that USDA’s Economic Research Service is back on the job and recovering somewhat from its forced move to Kansas City.  I was especially interested to see this report: U.S. Food-Related Water Use Varies by Food Category, Supply Chain Stage, and Dietary Pattern.

It has three main conclusions:

  • The U.S. food system, which provides the majority of domestically purchased foods and beverages, requires about one-third of the Nation’s total freshwater use.

  • Crop production uses over half of the water for food, while later supply chain stages also require a substantial amount of water.

  • Freshwater usage varies by the food categories that make up U.S. diets. If the U.S. population were to adopt healthier dietary patterns, food-system water use could substantially increase or decrease, depending on the dietary patterns realized.

Something to consider.  But all this is why PepsiCo is making such a big point about trying to reduce its water use (it takes many gallons of water to make one gallon of a bottled drink).
