As a journalist who takes issues surrounding food production seriously, I too have things that drive me crazy.

At the top of my list are agribusiness advocates such as Kopperud (and, more recently, Steve Sexton of Freakonomics) who dismiss well-thought-out concerns about today's dysfunctional food production system with the old saw that organic farming can't save the world. They persist in repeating this as an irrefutable fact, even as one scientific study after another concludes the exact opposite: not only that organic can indeed feed nine billion human beings but that it is the only hope we have of doing so.

"There isn't enough land to feed the nine billion people" is one tired argument that gets trotted out by the anti-organic crowd, including Kopperud. That assertion ignores a 2007 study led by Ivette Perfecto, of the University of Michigan, showing that in developing countries, where the chances of famine are greatest, organic methods could double or triple crop yields.

"My hope is that we can finally put a nail in the coffin of the idea that you can't produce enough food through organic agriculture," Perfecto told Science Daily at the time.

Too bad solid, scientific research hasn't been enough to drive that nail home. A 2010 United Nations study (PDF) concluded that organic and other sustainable farming methods that come under the umbrella of what the study's authors called "agroecology" would be necessary to feed the future world. Two years earlier, a U.N. examination (PDF) of farming in 24 African countries found that organic or near-organic farming resulted in yield increases of more than 100 percent. Another U.N.-supported report entitled "Agriculture at a Crossroads" (PDF), compiled by 400 international experts, said that the way the world grows food will have to change radically to meet future demand. It called for governments to pay more attention to small-scale farmers and sustainable practices -- shooting down the bigger-is-inevitably-better notion that huge factory farms and their efficiencies of scale are necessary to feed the world.

Suspicious of the political motives of the U.N.? Well, there's a study that came out in 2010 from the all-American National Research Council. Written by professors from seven universities, including the University of California, Iowa State University, and the University of Maryland, the report finds that organic farming, grass-fed livestock husbandry, and the production of meat and crops on the same farm will be needed to sustain food production in this country.

The Pennsylvania-based Rodale Institute is an unequivocal supporter of all things organic. But that's no reason to dismiss its 2008 report "The Organic Green Revolution" (PDF), which provides a concise argument for why a return to organic principles is necessary to stave off world hunger, and which backs the assertion with citations of more than 50 scientific studies.
