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.

There's new evidence that wild bees, some of nature's most industrious pollinators of wildflowers and crops, are getting squeezed by our planet's changing climate.

What if farmers, instead of picking up some agricultural chemicals at their local dealer, picked up a load of agricultural microbes instead?

It's something to contemplate, because some big names in the pesticide business — like Bayer and Monsanto — are putting money behind attempts to turn soil microbes into tools that farmers can use to give their crops a boost.

It's a symptom of the soaring interest in the ways microbes affect all of life. In our bodies, they help fight off disease. In the soil, they help deliver nutrients to plants, and perhaps much more.

Tyson Foods, the country's biggest poultry producer, is promising to stop feeding its chickens any antibiotics that are used in human medicine.

It's the most dramatic sign so far of a major shift by the poultry industry. The speed with which chicken producers have turned away from antibiotics, in fact, has surprised some of the industry's longtime critics.

For decades, the farmers who raise chickens, pigs and cattle have used antibiotics as part of a formula for growing more animals, and growing them more cheaply.

Bird flu has been striking chicken and turkey farms in parts of the West and Midwest. This past week, it hit a flock of millions egg-laying chickens in northeastern Iowa. Update 4/22/2015: The USDA now says that around 3 million birds were affected in the Iowa facility — down from a previous estimate of 5 million.

On the face of it, the new potato varieties called "Innate" seem attractive. If you peel the brown skin off their white flesh, you won't find many unsightly black spots. And when you fry them, you'll probably get a much smaller dose of a potentially harmful chemical.

But here's the catch: Some of the biggest potato buyers in the country, such as Frito-Lay and McDonald's, seem afraid to touch these potatoes. Others don't even want to talk about them because they are genetically modified organisms, or GMOs.

Within just a few days, on Jan. 1, all eggs sold in California will have to come from chickens that live in more spacious quarters — almost twice as spacious, in fact, as the cages that have been the industry standard.

It's been a shock to the egg industry, and to grocery stores. Eggs are one of those staples that self-respecting grocery retailers absolutely, positively have to keep in stock. "You have to have bread, milk, lettuce. You have to have eggs," says Ronald Fong, the president and CEO of the California Grocers Association.

For practically our whole history of cooking and eating, we've gotten our spices and most flavors (not to mention all of the other basic nutrients that keep us alive) straight from plants.

But researchers and biotech companies are starting to produce some of these nutrients and flavors — especially the high-priced ones — in their laboratories.

A colleague accosted me at the coffee machine the other day with an urgent question. "Why are pine nuts so expensive?"

I promised to find out. And I did. But along the way, I discovered something remarkable about pine nuts.

They connect us to a world of remote villages and vast forests, ancient foraging traditions that are facing modern threats.

Pine nuts don't generally come from orchards, or fields, or plantations. They come from pine forests. (And pine nuts are expensive because most of these areas are so remote.)

Perdue Farms says it has ditched the common practice of injecting antibiotics into eggs that are just about to hatch. And public health advocates are cheering. They've been campaigning against the widespread use of antibiotics in agriculture, arguing that it's adding to the plague of antibiotic-resistant bacteria.

In the shadows of West Africa's Ebola outbreak, food shortages are starting to develop.

This time of year is traditionally the lean season in West Africa, when last year's harvest of rice or groundnuts is mostly exhausted. Until recently, people were quite hopeful about the approaching harvest this year.

"The rainfall situation was very good," says Shukri Ahmed, a senior economist with the U.N.'s Food and Agriculture Organization in Rome. "We were actually developing an optimistic forecast for crop production this year."
