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.

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.

Why Are Pig Farmers Still Using Growth-Promoting Drugs?

In recent years, pork producers have found ways to keep the animals healthy through improved hygiene.

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.

Heat, Drought Draw Farmers Back To Sorghum, The 'Camel Of Crops'

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.

Kansas Farmers Commit To Taking Less Water From The Ground

The long arms of pivot irrigation rigs deliver water from the Ogallala Aquifer to circular fields of corn in northwestern Kansas.

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.

Why Lots Of Grass-Fed Beef Sold In U.S. Comes From Down Under

Patricia Whisnant, who runs Rain Crow Ranch in Doniphan, Mo., says her grass-fed beef can compete with the Australian product because it has a better story American consumers can connect with.

Beef from cattle that have grazed only on pasture is in high demand — much to the surprise of many meat retailers, who didn't traditionally think of grass-fed beef as top-quality.

George Siemon, a founder of Organic Valley, the big organic food supplier, says the push for grass-fed beef started with activists who wanted to challenge a beef industry dominated by factory-scale feedlots. In those feedlots, cattle are fed a corn-heavy diet designed to make the animals gain weight as quickly as possible.
