Water wars: View from the delta

Re: ImJustABill Aug. 6, 2015 @ 9:33 a.m. Don't forget almonds. "About 70% of California's almonds are sold overseas." http://www.latimes.com/business/la-fi-california-… I will need more data to reach a sensible conclusion about collusion, or, for that matter, the technical validity behind the conclusion that almond trees “use” more water than other tree crops. I’d like to see a competent study. I’m also unsure of the “statistic” about the amount of water required to produce a unit of almonds. In most cases, I suspect that the extra water is actually waste, rather than “use.” Depending upon whether or not a field is drained and what happens to the drainage water, some fraction of the “wasted” water just might end up recharging the water table. To what extent, I have no idea, but it is theoretically possible. However, theory should be the driver of research, not a surrogate for it (as is common in agronomic “studies”). If the LA Times piece is the result of disciplined journalism, that fact is well-hidden. No references to sources for the statistics are even mentioned, much less cited or linked. In the Internet age, there’s no excuse for refusing to provide links to sources (we all know that reporters do most, if not all their “research” on the Internet). The article says nothing about the ratio of water “used” to the unit-area, and provides no insight as to how that fact was determined. Almonds are a perennial crop (as are some other crops), so requiring that irrigation actually cease would not pencil out in positive territory, while the same would not be true for, say, alfalfa or rice which fields could be fallowed with minimal damage to the investment; however, if such a policy were put into action, equity should require that the losses should at least partially offset by payments out of almond and other beneficiaries of the policy.
