How will climate change affect U.S. crop yields?

As the UN climate conference kicks off in Egypt, food and agriculture are central to negotiations for the first time. More severe droughts, warmer temperatures and heavier rainfall fueled by climate change are making it harder than ever for the world’s one billion farmers to grow food and fiber. While some farms and regions are more vulnerable than others, climate change will affect farmers everywhere.

Here in the U.S., where farmers have a long history of steadily increasing yields, climate change will likely cause crop productivity gains to stall — or even reverse — as soon as 2030.

Farmers’ voices are essential to figuring out sustainability. Let’s listen up.

The corn and soybean fields that stretch for miles across the Midwest are quiet this time of year, mostly frozen surfaces waiting for the spring planting season.The corn and soybean fields that stretch for miles across the Midwest are quiet this time of year, mostly frozen surfaces waiting for the spring planting season.

Although many farmers are not in the field dawn to dusk during the winter, they are still plenty busy. Between planning for the next season, taking care of animals and attending countless meetings, farmers are seldom idle even if their crop fields are.

But lucky for us, winter does afford more time to talk.

One friend from Iowa who works hard to use fertilizer efficiently to avoid runoff and optimize plant uptake of nutrients said he worries that food companies don’t always recognize the sustainability efforts of mainstream farmers. Too often, he said, it seems food companies look for simple labels like organic.

A soybean grower I know from Ohio who has invested a lot of time learning farming practices that will help restore nearby Lake Erie told me it is a constant struggle to balance making a living with repairing decades of agricultural nutrient runoff that have imperiled the health of the lake.

How cover crops can help growers beat droughts and floods

Cover crops can include grasses like cereal rye.

Cover crops can include grasses like cereal rye.

Corn is trying to fight this summer’s extreme weather, and unfortunately, the weather is winning.

There are serious floods in the Midwest, devastating droughts in California, and brutal heat waves along the eastern seaboard. Ohio for example had a record June rainfall of 11 inches, which stunted corn roots and prevented many growers from planting any corn crops. In Northwest Ohio alone, 100,000 acres were left unplanted. At the same time, places in my home state of North Carolina experienced a June heat wave during the critical corn pollination period, significantly damaging corn yields.

These extreme weather events leave many farmers searching for ways to make the best of a challenging growing season. Although June’s weather was the opposite in Ohio and North Carolina, cover crops offer a proven solution to deal with both conditions. Read More »
