Iowa Crops Look Like Food — But No One’s Eating
Inside a system that traps farmers and screws up the planet
--
I was in Iowa last week shooting for the PBS NewsHour Weekend “Future of Food” series. There are some good things going on — and you’ll see them in the segment, which will run later this summer or fall — but I left feeling depressed as hell. It’s bad enough that Iowa plays an outsized role in determining presidential candidates; its population, after all, is less than 1 percent of the country’s. But its impact on the food system is even greater, and may be even more difficult to change.
Iowa has its beauty: It’s not flat, as many seem to believe, and although the scenery is not especially dramatic, this time of year it’s lush, with free-flowing waterways everywhere. Iowa farmers generally do not irrigate, which distinguishes the state from California, of course, as does the astonishing dominance of the almost exclusively two-crop economy based on corn and soybeans.
Yet Iowa is unrecognizable from centuries ago, when Europeans took the land for themselves. What were prairie and wetlands are now neatly partitioned grids of intensely cultivated land: the model for the farm as factory. Through a system of underground “tiles” (pipes, really) in the northern half of the state, most of the water has been drained from swamps, prairie potholes, and lakes into creeks and rivers, which in turn have been engineered to maximize flow.
Thus, much of the landscape has been reshaped to make large-scale mechanical farming as productive as possible. Twenty-three million acres are planted in corn and/or soybeans; that’s 63 percent of all the land in the state, and more than the land area of each of 20 states. Nor is Iowa alone. An area the size of Montana is planted in corn every year in the United States; less than 1 percent of that is sweet corn eaten by humans.
Farmers talk of crops and equipment and prices, but not of food.
(Well, except for when they claim to be “feeding the world,” which simply isn’t true.) The ground is barely used for growing food: The grain elevator — the point of contact between the farmer and the industrial commodity system — buys only corn and soybeans. It’s near…
