It’s Long Past Time to Police Big Agriculture’s Water Waste

When you observe water-stressed and drought-stricken areas around the world, you hear the same question being asked again and again: Who uses the most water? A common assumption leads people to blame the general population for its wasteful ways, heedlessly watering their lawns and washing their cars despite a water shortage. But the real answer, in most cases, is agriculture — and not by a small measure. It often accounts for 70% to 80% of total water use, and sometimes more.

Irrigation and other water uses in agriculture, especially where it is a major industry for domestic and export food production, such as California’s Central Valley, make other water uses look like drops in a bucket. According to a 2012 study by the Pacific Institute, the Golden State’s 38 million people use just 4% of its water, while agriculture, including the raising of both crops and livestock, uses 93%.

The reason this matters so much is that Big Agriculture wastes epic amounts of water and often fights efficiency measures on the basis of cost. California, to stick with that example, uses much less drip irrigation than other arid farming regions of the world. Generally, efficiency standards and enforcement are not in place, which allows massive amounts of water to leak out of systems. And much of the water used simply evaporates because it is not recaptured. This goes on while agricultural users pump out deep aquifers’ groundwater far faster than it can be restored naturally, especially in times of drought.

The types of agriculture matter for the scale of water usage, as well. California rice growers flood the fields, whereas another crop might need only sips of water, relatively speaking. Beef producers use about 2,500 gallons of water per pound (as opposed to 100 gallons of water per pound of grain).  Although costly, relocating water-intensive agriculture from water-stressed regions to places where water is most abundant would make sense. In the U.S., that might mean moving some practices from the Southwest to the Southeast. In China, it would mean moving farms  from the arid north to the wet south. But in many countries, business and political interests would keep it from happening as long as possible, and in the end, severe water shortage and escalating costs would force the issue.

Where you have a massive industry, you have a wealthy lobby with a lot of political power to influence government spending. Critics of California’s $7.5 billion drought bond known as Proposition 1, to be voted on in statewide elections on Tuesday (4 November; update — it passed by a two-to-one margin), note that it provides for new dams and water-storage measures that will benefit agriculture. But it’s not yet clear what might be asked in return. About $50 million of the $7.5 billion appears to be earmarked for agricultural efficiency. Will future measures mandate adequate technology and standards of efficiency? Ultimately, the nine-member California Water Commission will decide how funds from the Prop. 1  bond measure, if passed, will be spent.  They should know that the industries using nine-tenths of the state’s water should be doing a lot more to help ease the region’s water crisis.
