Dpi urges caution over record cropping predictions

As the world burns, scientists worry that record crop growth may take us into trouble.

But while the world is increasingly consuming more and more food, climate experts are warning that while climate change is altering crops and ecosystems, other forces like increased water shortages, crop pests, and other threats are making it harder for crop yields to meet demand.

“We’re seeing record crop growth,” said Matthew Barringer, an ecologist at Colorado State University in Fort Collins. “Even in the U.S., we’re seeing higher rates of water use.”

By 2015, the United States will burn more water per capita than any other nation. And while global carbon emissions are shrinking, they are still higher than they have been in recent years.

Yet scientists a우리카지노re still divided as to whether current trends, coupled with the challenges facing the U.S. at a time of unprecedented drought, are a recipe for future climate change.

In some areas, such as in parts of California and Colorado, higher irrigation rates could potentially bring a new crop into existence while reducing the use of some other crops. These findings were published Monday in Proceedings of the National Academy of Sciences.

To make the connection, Barringer and his colleagues analyzed more than 30 years of crop field experiments that used more than 12,000 crogospelhitzp types, including barley, corn, and soybean.

They focused on the U.S. Midwest for this project because there’s high global crop yield potential in that area, says Anthony Lofstro바카라사이트m, an Earth Systems researcher at Missouri State University, St. Louis.

“And so, we are a really big region of crops and water that is growing pretty rapidly,” says Lofstrom, who wasn’t involved in Barringer’s research. “So, this research has been particularly interesting because of its global scope — but also its location, which makes it very important to understand the effects of climate change on that area.”

To conduct the study, Lofstrom, Barringer and their colleagues analyzed data from more than 2,300 studies that looked at crop size, yield, nitrogen and phosphorus, and other traits.

By adding global data — including data from the U.S. Environmental Protection Agency’s National Agricultural Data Network — the researchers combined these data with the results of field experiments, which used about 3,000 U.S. farmers in 10 regions over 10 years.

What they found, in a nutshell, is that while the
