Daniel 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.

For a while there, China was the American farmer's best friend. The world's most populous nation had so many pigs and chickens to feed, it became one of the top importers of U.S. corn and soybeans almost overnight.

Consider, for a moment, the misfortunes of winemakers in Moldova, a former Soviet republic in southeastern Europe, tucked in between Ukraine and Romania.

Their country is the poorest in Europe, with a per capita GDP about the same as Honduras. They'd love to sell their product — which has gotten approving nods from foreign critics -- in wealthier countries. But most of those customers don't even know that Moldova exists, let alone that its winemaking tradition goes back thousands of years.

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.

Foster Farms, a chicken producer in California, just can't seem to stop bleeding bad news.

Somewhere in Iowa, volunteers are earning $900 apiece by providing blood samples after eating bits of a banana kissed with a curious tinge of orange.

It's the first human trial of a banana that's been genetically engineered to contain higher levels of beta carotene, the nutrient that our body converts into vitamin A. Researchers want to confirm that eating the fruit does, in fact, lead to higher vitamin A levels in the volunteers' blood.

The volunteers in Iowa may not realize it, but they're playing a small part in a story that spans the globe.

Yesterday, we reported on a legal tussle over control of the country's top center of strawberry breeding, at the University of California, Davis. But there's a backstory to that battle. It involves the peculiar nature of the UC Davis strawberry program.

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.

Some people have had it with "natural" food.

For fifteen years, Urvashi Rangan, director of consumer safety and sustainability for Consumer Reports, has been pointing out that "natural" is just about the most misleading label that you'll ever see on a food package. Yet consumers still look for that word, food companies still love to use it and the Food and Drug Administration can't or won't define it.

If you're a listener, you may recognize the name New Morning Farm.

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.

Baltimore's seaport is a world of big, noisy steel machines: giant cargo ships, cranes and roaring trucks.

In the middle of this hubbub, David Ng, an agricultural specialist with U.S. Customs and Border Protection, tries to find things that are small and alive: snails, moths and weed seeds of all sorts.

Imagine if a gallon of milk cost $3 in your town, but 100 miles away it cost $100, or even $200.

Something similar is happening right now in California with water that farmers use to irrigate their crops. Some farmers are paying 50 or even 100 times more for that water than others who live just an hour's drive away.

The situation is provoking debate about whether water in California should move more freely, so that it can be sold to the highest bidder.

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.

In the future, Earth's atmosphere is likely to include a whole lot more carbon dioxide. And many have been puzzling over what that may mean for the future of food crops. Now, scientists are reporting that some of the world's most important crops contain fewer crucial nutrients when they grow in such an environment.

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.

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.

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.

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 planet's top experts on global warming released their latest predictions this week for how rising temperatures will change our lives, and in particular, what they mean for the production of food.

McDonald's made a big green splash a few months ago by announcing that it will start buying "verified sustainable" beef in 2016.

A chorus of voices responded, "What's 'verified sustainable' beef?"
