Happy Water Day, World!

A huge amount of water goes into the food we eat, much more than most people think. Indeed, it takes a thousand times more water to feed the human population than it does to satisfy its thirst.

This remarkable relationship between water and food security is exactly what the United Nations Food and Agriculture Organization wants us all to contemplate today, World Water Day 2012.

Since the first of these annual campaigns, in 1993, World Water Day has been organized around a theme. The focus last year was “Water for Cities.” In 1995, it was “Women and Water.” This year, organizers are reminding us all that water conservation is one good reason to eat lower on the food chain:

It takes about 1,500 liters of water to produce 1 kilogram of wheat; producing the same amount of beef takes 15,000 liters.

The FAO warns that feeding the 9 billion people expected to populate the planet by 2050 simply won’t be possible unless we figure out how to grow more food with less water. Already 70 percent of fresh water collected for human consumption is put toward irrigation. If more of those irrigated crops fed people rather than cattle, we would be headed in a step in the right direction. But it’s going to take smarter application of water as well.
