This is why California’s water shortage is really a lack of accurate pricing

David Henderson explains:

Of the 80 million acre feet a year of water use in California, only 2.8 million acre feet are used for toilets, showers, faucets, etc. That’s only 3.5 percent of all water used.

One crop, alfalfa, by contrast, uses 5.3 million acre feet. Assuming a linear relationship between the amount of water used to grow alfalfa and the amount of alfalfa grown, if we cut the amount of alfalfa by only 10 percent, that would free up 0.53 million acre feet of water, which means we wouldn’t need to cut our use by the approximately 20 percent that Jerry Brown wants us to.

What is the market value of the alfalfa crop? Alexander quotes a study putting it at $860 million per year. So, assuming, for simplicity, a horizontal demand curve for alfalfa, a cut of 10% would reduce alfalfa revenue by $86 million. (With a more-realistic downward-sloping demand for alfalfa, alfalfa farmers would lose less revenue but consumers would pay more.) With a California population of about 38 million, each person could pay $2.26 to alfalfa growers not to grow that 10%. Given that the alfalfa growers use other resources besides water, they would be much better off taking the payment.

Artillery Crisis on the Western Front – The Fall of Windhoek I THE GREAT WAR Week 42

The 2nd Battle of Ypres is still going but no side can gain a decisive advantage. The main reason on the British side is a lack of artillery ammunition. Even the delivered shells are not working correctly. But even the German supply lines are stretched thin. At the same time German South-West Africa falls to South African troops under Louis Botha.

Women in front-line combat trades

At Strategy Page, a look at the political desire to fully integrate women into the combat arms:

In 2014, after years of trying to justify allowing women into the infantry, artillery and armor and special operations forces, the U.S. government decided to just order the military to make it happen and do so without degrading the capabilities of these units. While the army was inclined the just say yes, find out what quotas the politicians wanted and go through the motions, others refused to play along. SOCOM (Special Operations Command) and the marines pointed out that the research does not support the political demands and that actually implementing the quotas could get people killed while degrading the effectiveness of the units involved. This is yet another reason why many politicians do not like the marines and are uneasy about SOCOM.

But action had to be taken and orders were orders. The various services opened up some infantry training programs to women and have discovered two things. First (over 90 percent) of women did not want to serve in any combat unit, especially the infantry. Those women (almost all of them officers) who tried out discovered what female athletes and epidemiologists (doctors who study medical statistics) have long known; women are ten times more likely (than men) to suffer bone injuries and nearly as likely to suffer muscular injuries while engaged in stressful sports (like basketball) or infantry operations. Mental stress is another issue and most women who volunteered to try infantry training dropped out within days because of the combination of mental and physical stress. Proponents of women in combat (none of them combat veterans) dismiss these issues as minor and easily fixed, but offer no tangible or proven solutions.

Back in 2012 the U.S. Army and Marine Corps were ordered to come up with procedures to select women capable of handling infantry and special operations assignments and then recruit some women for these jobs. This had become an obsession with many politicians. None of these proponents of women in the infantry have ever served in the infantry, but they understood that if they proceeded without proof that women could handle the job, that decision could mean getting a lot of American soldiers and marines killed. The politicians also knew that if it came to that, the military could be blamed for not implementing the new policy correctly.

So far the tests, overseen by monitors reporting back to civilian officials in Congress and the White House, have failed to find the needed proof that women can handle infantry combat. The main problem the military has is their inability to make these politicians understand how combat operations actually work and what role sheer muscle plays in success, or simply survival. But many politicians have become obsessed with the idea that women should serve in the infantry and are ignoring the evidence.

Wine may not be acceptable for vegan diets

By way of Real Clear Science, Sara Rennekamp explains how a product made of (mostly) grapes might still not be acceptable for dedicated vegans:

Is your wine vegan? It seems like an odd question: wine is made of grapes, grapes fall solidly under the “not an animal product” label, therefore it would seem that wine is a vegan-friendly beverage.

However, many people who adhere to a vegan diet refrain from consuming any food or drink that is processed using animal products as well as the animal products themselves. Unfortunately for vegans, some wines are processed using animal products.

The culprit: a process called fining.

The fining process, when it is used, allows winemakers to remove unwanted compounds from wine either before or after the juice is fermented. There are several reasons that a winemaker might elect to fine his wine, according to Jim Law, the owner and winemaker of Linden Vineyard in Virginia. One reason is to clarify the wine. Another reason might be to fine-tune the taste or correct an imperfection. There are other reasons, but most fining is done to address these two issues.

But before getting into the whys of fining, it’s helpful to know what the fining process does.

Freshly pressed grape juice contains a lot more than just juice. As the grapes are pressed bits of seeds, stems and skin can all make their way through the press and into the liquid wine-to-be. These add-ons can form unsightly sediment in the wine and produce an unwanted flavor to the wine, oftentimes bitterness or astringency.

Some wine makers fine their wine to get the interloping roughage out of the wine before it ends up in your glass. Wines can also be filtered to remove particles and some unwanted sediment, but only the fining process can remove imperfections like unwanted compounds that are too small to be caught by a filter, such as tannins and other phenols, and proteins.

QotD: Portuguese genetics

On the face of it it sounds like the nice narrative we are fed every time something like this happens. I haven’t been following the international scene, and frankly it wouldn’t even surprise me if Europe headed for nativism and blood-related nationality. It is what is at the basis of their nation states (even if it’s often a lie. For instance I’d hazard that a lot of people in Portugal — yes, d*mn it, I’ll do the DNA testing. Let the house sell and let me have some money first — are as mixed as Americans. My kids call Portugal the reservoir tip at the end of Europe, which is unkind but somewhat accurate since that portion of land was part of the Celtic commonwealth, before being invaded by Carthaginians, Greeks, Romans, Germanic tribes, Moors (though their contribution in the North is minimal as the North was usually administered by overseers with little or no actual colonization) French crusaders, Viking raiders. Then there were British and Irish merchants due to ties going back before the Carthaginians who would set up trading posts, send their younger sons over, sometimes engage in a bit of raiding, etc. There are unkind proverbs about blue eyed Portuguese, but there are also a lot of them. (Two of my grandparents. A third was green eyed.) And in the end sometimes I think all of us are the result of some girl who tripped (on purpose or not) while evading a foreigner. All this to say that when my dad talks of the “The Portuguese Race” (and boy, does he) he’s mostly talking of a mythical entity. But it’s one they all believe in as hard as they can.)
