Every 5 years, the United States has the process of renewing its omnibus farm invoice. The present laws, the Agricultural Act of 2014, expires in September 2018, and new drafts are already being debated. The invoice is designed to assist farmers and the meals neighborhood, primarily based on the U.S. wants for vitamin, crop insurance coverage, conservation and different commodity packages.
So what affect does a significant crop like corn — the United States’ most dominant by way of acreage — and its farmers play in shaping the subsequent farm invoice? Rather a lot.
In 2016, for example, U.S. corn farmers yielded a complete of 86.7 million acres (35.1 million hectares) of corn. This crop was valued at $51.5 billion, far exceeding the $40 billion worth of America’s 2nd largest meals crop: soybeans.
Where does this corn go? The reply would possibly shock you. Just 205 million bushels (or 1.4 %) of the 15.1 billion bushels produced in 2016 went to cereal and different meals. (An common bushel of corn weighs about 56 kilos.) Another 480 million bushels (three.three %) went to make excessive-fructose corn syrup, a sweetener utilized by the meals trade. And a big share — 15 % — or 2.2 billion bushels was exported.
Much of the relaxation goes to feed livestock (5.6 billion bushels, 46 %) or to provide ethanol (4.2 billion bushels, 28.9 %). In reality, corn is the most generally produced feed grain in the United States.
What these statistics imply is the U.S. devotes greater than 90 million acres (36.4 million hectares) of farmland to corn, however little or no of that’s grown for human consumption. “People need to stop thinking about corn as food,” says Mark Lambert, senior communication director at the National Corn Growers Association. “It’s very versatile. It’s not just food. We’re growing way, way more than what we need for food purposes because we can.”
But does “as a result of we can” imply we ought to? The reply is advanced and multifaceted. First, the Agricultural Act of 2014 contains a number of completely different farm subsidies and sorts of crop insurance coverage, which may have influenced why the U.S. grows a lot corn. Before the late 1990s, crop insurance coverage was designed to help farmers when crop yields fell quick from disasters like climate.
However, in keeping with Colin O’Neil, agriculture coverage director at Environmental Working Group, these subsidy packages now pay out no matter crop yields. They’re subsidizing income as an alternative. Take 2016, for instance. Corn growers had a report 12 months; keep in mind, 86 million acres (35.1 million hectares) of corn was harvested value $51.5 billion. But many farmers have been nonetheless in a position to acquire subsidy funds as a result of the 2016 harvest worth for corn was set at $three.49 per bushel, 10 % decrease than the $three.86 projected worth.
So why the shortfall in corn costs in 2016? Perhaps it was as a result of easy provide and demand. Take 2016 once more: It was the 3rd-largest corn crop haul planted in the U.S. since 1944. So with such a powerful demand and huge provide, the worth per bushel went down, leaving taxpayers to choose up the distinction through subsidy funds.
And whether or not the U.S. ought to develop a lot corn is not only a query of economics; it is also a query of excellent environmental coverage. In 2014, for instance, the U.S. authorities’s National Climate Assessment analysis program reported that local weather change may considerably influence the Midwest and the Great Plains in the coming years, lowering yields and driving costs greater. The purpose is straightforward: Corn is a thirsty crop that may be simply impacted by excessive drought, devastating warmth waves and the lack of precipitation. Crop yields decline when temperatures get hotter and rainfall is proscribed.
Corn additionally consumes a considerable amount of freshwater, roughly 5.6 cubic miles per 12 months — that is about 6.1 trillion gallons (about 23 trillion liters). That water comes from lakes, rivers, streams and underground aquifers. Heavy rain can delay planting and reduce manufacturing.
Runoff from these farmlands can be one other environmental concern. Corn makes use of extra fertilizer than different crops, about 5.6 million tons (5 metric tons) of nitrogen fertilizer annually. As a end result, the chemical substances and soil wash into waterways when it rains, polluting rivers, streams and oceans. The outcomes might be seen in the Gulf of Mexico the place scientists say extreme nutrient air pollution has created a hypoxic, or low-oxygen, useless zone for aquatic life at the mouth of the Mississippi River.
And all that corn that the U.S. turns into clear-burning ethanol? Environmentalists say ethanol manufacturing is not environment friendly. Growing and processing corn into biofuel makes use of an enormous quantity of land and fossil gas, which in the end negates any environmental advantages.
Some suppose the method to repair the downside is to craft a farm invoice that may prioritize farming of more healthy meals which can be grown in additional environmentally pleasant methods. Jonathan Foley, govt director of the California Academy of Sciences, wrote: “This reimagined agricultural system would be a more diverse landscape, weaving corn together with many kinds of grains, oil crops, fruits, vegetables, grazing lands and prairies. Production practices would blend the best of conventional, conservation, biotech and organic farming. Subsidies would be aimed at rewarding farmers for producing more healthy, nutritious food while preserving rich soil, clean water and thriving landscapes for future generations. This system would feed more people, employ more farmers, and be more sustainable and more resilient than anything we have today.”
