To “feed the world” by 2050, we’ll need a massive, global ramp-up of industrial-scale, corporate-led agriculture. At least that’s the conventional wisdom.

Even progressive journalists trumpet the idea (see here, here, and here, plus my ripostes here and here). The public-radio show Marketplace reported it as fact last week, earning a knuckle rap from Tom Laskway. At least one major strain of President Obama’s (rather inconsistent) agricultural policy is predicated on it. And surely most agricultural scientists and development specialists toe that line … right?

Well, not really. Back in 2009, Seed Magazine organized a forum predicated on the idea that a “scientific consensus,” analogous to the one on climate change, had formed around the desirability of patent-protected genetically modified seeds. If I must say so, my own contribution to that discussion shredded that notion. If anything, a pro-GMO consensus has formed among a narrow group of microbiologists — the people who conduct gene manipulations to develop novel crops. But no such accord exists among scientists whose work takes them out of the laboratory and into farm fields and ecosystems: soil experts, ecologists, development specialists, etc.
