Researchers have quantified just how much water the agriculture industry in the Western U.S. is taking from the Colorado River, one of the most important river systems in the region.

More than half of the Colorado River's total annual water flow is being used to irrigate agricultural land, according to a paper published Thursday in Communications Earth & Environment.

Waters from the Colorado River have not reached its delta in the Gulf of California for more than 50 years because nearly every drop is being consumed as the waters flow south, Brian Richter, president of Sustainable Waters, a global water education service, senior freshwater fellow at the World Wildlife Fund, told ABC News.

In this situation, it's actually growing alfalfa in an arid climate because water access from the river is use-it-or-lose-it based on an imaginary amount of water that don't exist.

If you can provide the water, desert is the most productive and fertile farmland in the world. But if we can't provide the water, we will need more farmland elsewhere to make up the loss.

Alfalfa is a highly water intensive crop. The alfalfa being grown in the southwest is almost entirely exported.
