Are Water Resources Keeping Up?

As the writer at the Federal Reserve Bank commented in his article Are Water Resources Keeping Up with U.S. Economic Needs? – San Francisco Fed water is not something we can transport from a water rich area to a water poor one.  While the research studies cited in the article advise that the United States is not over-all water short, the arable where the United States depends for its fresh fruits and vegetables, are those areas most water short. 

The unstated suggestion of the author is simply that we could move agricultural production to the water rich areas. But the author does not opine on what crops can be grown in the “water rich” areas.  It may be that if indeed we must move crop production to the Midwest where the growing season does not produce 3-5 crops per year of the vegetables that US citizen have come to love from southern California that American’s diets will be require change or that a larger share of individual gross income will be spent on food.
