California's Drought Isn't Making Food Cost More. Here's Why

Farmworkers pull weeds from a field of lettuce near Gonzales, Calif. Salinas Valley farms like this one rely on wells, which haven't been affected much by the drought.

The entire state of California is in a severe drought. Farmers and farmworkers are hurting.

You might expect this to cause food shortages and higher prices across the country. After all, California grows 95 percent of America's broccoli, 81 percent of its carrots and 99 percent of the country's artichokes, almonds and walnuts, among other foods.

Yet there's been no sign of a big price shock. What gives?

Here are three explanations.

If you're drinking a cup of coffee right now, treasure it. The global supply of coffee beans may soon shrink because of problems in coffee-growing areas of Brazil and Central America.

With supply threatened and demand strong, prices are taking flight. Wholesale coffee prices are up more than 60 percent since January — from $1.25 per pound of bulk Coffea arabica beans to $1.85 this week.

Here in the news biz, we rely on thumbnail descriptions, sparing you the details. We'll tell you, for instance, that organic farmers aren't allowed to use synthetic pesticides and factory-made fertilizer.

In general, that's true. But there's also a long list of pesky exceptions to the rule. And this week, a battle erupted over those exceptions: the synthetic or factory-made substances that organic farmers are still allowed to use because the farmers say they couldn't survive without them.

For the past month, in part of eastern Kansas, the prairie has been burning, as it does almost every spring. On some days, you could look toward the horizon in any direction and see pillars of smoke. The plumes of pollution have traveled so far that they've violated limits for particulates or ozone in cities as far away as Lincoln, Neb.

But here's the twist: Environmentalists have come to celebrate those fires.

It could be another milestone in organic food's evolution from crunchy to commercial: Wal-Mart, the king of mass retailing, is promising to "drive down organic food prices" with a new line of organic food products. The new products will be at least 25 percent cheaper than organic food that's on Wal-Mart's shelves right now.

Plant Breeders Release First 'Open Source Seeds'

Backers of the new Open Source Seed Initiative will pass out 29 new varieties of 14 different crops, including broccoli, carrots and kale, on Thursday.

A group of scientists and food activists is launching a campaign Thursday to change the rules that govern seeds. They're releasing 29 new varieties of crops under a new "open source pledge" that's intended to safeguard the ability of farmers, gardeners and plant breeders to share those seeds freely.

It's inspired by the example of open source software, which is freely available for anyone to use but cannot legally be converted into anyone's proprietary product.

Can Fish Farms Thrive In The USA?

Why hasn't fish farming taken off in the United States?

It's certainly not for lack of demand for the fish. Slowly but surely, seafood that's grown in aquaculture is taking over the seafood section at your supermarket, and the vast majority is imported. The shrimp and tilapia typically come from warm-water ponds in southeast Asia and Latin America. Farmed salmon come from big net pens in the coastal waters of Norway or Chile.
