"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.
Rodale concludes that farming must move away from using unsustainable, increasingly unaffordable, petroleum-based fertilizers and pesticides and turn to "organic, regenerative farming systems that sustain and improve the health of the world population, our soil, and our environment." The science the report so amply cites shows that such a system would
- give competitive yields to "conventional" methods
- improve soil and boost its capacity to hold water, particularly important during droughts
- save farmers money on pesticides and fertilizers
- save energy because organic production requires 20 to 50 percent less input
- mitigate global warming because cover crops and compost can sequester close to 40 percent of global CO2 emissions
- increase food nutrient density
The most troubling part of Kopperud's post is where he says that he finds the food movement of which Pollan and Nestle are respected leaders "almost dangerous." He's wrong. The real danger is when an untruth is repeated so often that people accept it as fact.
Given that the current food production system, which is really a 75-year-old experiment, leaves nearly one billion of the world's seven billion humans seriously undernourished today, the onus should be on the advocates of agribusiness to prove their model can feed a future population of nine billion -- not the other way around.
