Dan Charles

Dan Charles is NPR's food and agriculture correspondent.

Primarily responsible for covering farming and the food industry, Charles focuses on the stories of culture, business, and the science behind what arrives on your dinner plate.

This is his second time working for NPR; from 1993 to 1999, Charles was a technology correspondent at NPR. He returned in 2011.

During his time away from NPR, Charles was an independent writer and radio producer and occasionally filled in at NPR on the Science and National desks, and at Weekend Edition. Over the course of his career Charles has reported on software engineers in India, fertilizer use in China, dengue fever in Peru, alternative medicine in Germany, and efforts to turn around a troubled school in Washington, DC.

In 2009-2010, he taught journalism in Ukraine through the Fulbright program. He has been guest researcher at the Institute for Peace Research and Security Policy at the University of Hamburg, Germany, and a Knight Science Journalism fellow at the Massachusetts Institute of Technology.

From 1990 to 1993, Charles was a U.S. correspondent for New Scientist, a major British science magazine.

The author of two books, Charles wrote Master Mind: The Rise and Fall of Fritz Haber, The Nobel Laureate Who Launched the Age of Chemical Warfare (Ecco, 2005) and Lords of the Harvest: Biotech, Big Money, and the Future of Food (Perseus, 2001) about the making of genetically engineered crops.

Charles graduated magna cum laude from American University with a degree in economics and international affairs. After graduation Charles spent a year studying in Bonn, which was then part of West Germany, through the German Academic Exchange Service.

Maybe you've wondered, while looking at the price tag on some organic produce, whether that label is telling the truth.

Peter Laufer, a writer and professor of journalism at the University of Oregon, doesn't just wonder. He's an outright skeptic, especially because the organic label seems to him like a license to raise prices. And also because those products are arriving through supply chains that stretch to far corners of the world.

There may never be an end to arguments over whether organic food is more nutritious. But a new study is the most ambitious attempt so far to resolve the issue — and it concludes that organic fruit and vegetables offer a key benefit.

In California, a legal skirmish has erupted over strawberries — or rather, over strawberry breeding.

To be absolutely precise, the battle is about strawberry breeding at the University of California, Davis. This is more important than it might sound. More than half of all strawberries in the supermarket trace their ancestry to breeding plots at UC Davis.

The strawberry breeders at UC Davis, who've led that program for decades, are leaving the university to carry on their work at a new private company.

It seems that everybody, going back at least to Thomas Jefferson, loves small family farms.

Yet those beloved small farms are becoming increasingly irrelevant. Big farms are taking over.

According to the latest census of American agriculture, released this year, there are two million farms in America. But just four percent of those farms account for two-thirds of all agricultural production.

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.

Every five years, the U.S. Department of Agriculture carries out a census of farmers: who they are, and what they are doing on their farms.

The agency just released the latest one, and it's a feast for all ag geeks. And here's the very first, most basic piece of new information: There are 2,109,303 farmers in this country.

But look a little closer at that number, and you can see that it's not quite what it seems. Most of those farmers are not actually making a living by farming.

Chalk up another win for citizen activists. Coke and Pepsi announced this week that they will no longer use brominated vegetable oil, or BVO, in their soft drinks.

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.

The other morning, I found myself staring at something strange and unfamiliar: empty grocery shelves with the word "eggs" above them. The store, a Whole Foods Market in Washington, D.C., blamed, in another sign, the dearth on "increased demand for organic eggs."

This scene is unfolding in grocery stores across the country. But Whole Foods' sign wasn't telling the whole truth. Demand for organic eggs is indeed increasing, but production is also down.

The reason behind that shortfall highlights an increasingly acute problem in the organic industry.

Christopher Leonard's new exposé on the chicken industry, The Meat Racket, doesn't devote much ink to the physical object on our plate, the chicken meat itself.
