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.

As the year winds down, we here at NPR are looking at a few key numbers that explain the big trends of 2013.

Today's number: 1.6 million.

That's 1.6 million acres — about the area of the state of Delaware.

That's how much land was removed this year from the federal Conservation Reserve Program, or CRP, which pays farmers to keep land covered with native grasses or sometimes trees. Most of that land now will produce crops like corn or wheat.

If you think grains of rice or kernels of corn are free gifts of nature, think again. Seed companies — and the FBI — take a very different attitude, and walking off with the wrong seeds can land you in very serious trouble indeed.

In two apparently unrelated cases this week, federal prosecutors arrested citizens of China and charged them with stealing seeds that American companies consider valuable intellectual property.

If drug companies follow guidance issued Wednesday by the Food and Drug Administration, within three years it will be illegal to use medically important antibiotics to make farm animals grow faster or use feed more efficiently.

The FDA's announcement wasn't a big surprise; a draft version of the strategy was released more than a year ago.

The anti-poverty group Oxfam is asking Pepsi's shareholders to approve a resolution that, if passed, would force the company to disclose its sugar suppliers and investigate whether those suppliers are implicated in "land grabs" that unfairly take land from the poor.

Many organic farmers are hopping mad at the U.S. Food and Drug Administration, and their reason involves perhaps the most underappreciated part of agriculture: plant food, aka fertilizer. Specifically, the FDA, as part of its overhaul of food safety regulations, wants to limit the use of animal manure.

"We think of it as the best thing in the world," says organic farmer Jim Crawford, "and they think of it as toxic and nasty and disgusting."

Emergency aid, including stocks of food, started arriving this week in cyclone-devastated areas of the Philippines; more is on the way.

The first wave of aid — high-energy biscuits designed to keep people alive when food is scarce — arrived via airlift. Huge shiploads of rice will be needed in the weeks and months to come. And exactly how the U.S. donates of that rice is a flashpoint in a long-running debate in Washington, D.C., about food aid.

Food labels have become battlegrounds. Just last week, voters in Washington state narrowly defeated a measure that would have required food manufacturers to reveal whether their products contain genetically modified ingredients.

Supporters of the initiative — and similar proposals in other states — say that consumers have a right to know what they're eating.

But there are lots of things we might want to know about our food. So what belongs on the label?

If the Food and Drug Administration has its way, an era of food technology will soon end. The agency announced Thursday it is aiming to ban partially hydrogenated vegetable oils from all food products.

Margaret Hamburg, the FDA commissioner, said at a press conference that her agency has come to the preliminary conclusion that the oils "are not generally recognized as safe for use in food."

If the agency makes this decision final, it will mean a complete ban on this ingredient.

It's one of the most controversial practices in agriculture: feeding small amounts of antibiotics to animals in order to make them grow faster.

But what if the drugs don't even work very well?

There's some good evidence that they don't, at least in pigs. They used to deliver a boost in growth, but that effect has disappeared in recent years or declined greatly.

The reason for this is interesting and even paradoxical.

In a barn outside Manhattan, Kan., researchers from Kansas State University are trying to solve the riddle of bovine respiratory disease. They're sticking plastic rods down the noses of 6-month old calves, collecting samples of bacteria.

Much of the world is turning hotter and dryer these days, and it's opening new doors for a water-saving cereal that's been called "the camel of crops": sorghum. In an odd twist, this old-fashioned crop even seems to be catching on among consumers who are looking for "ancient grains" that have been relatively untouched by modern agriculture.

Sorghum isn't nearly as famous as the big three of global agriculture: corn, rice and wheat. But maybe it should be. It's a plant for tough times, and tough places.

If you've flown across Nebraska, Kansas or western Texas on a clear day, you've seen them: geometrically arranged circles of green and brown on the landscape, typically half a mile in diameter. They're the result of pivot irrigation, in which long pipes-on-wheels rotate slowly around a central point, spreading water across cornfields.

Yet most of those fields are doomed. The water that nourishes them eventually will run low.
