The sunflower crop, also known as the yam, has been a staple of the American diet for centuries, but the crop is increasingly threatened by drought.
The US Department of Agriculture says that the U.S. has more than 1.3 million acres of yams, a number that is expected to double to more than 2.6 million acres by 2040, with more than half of those acres being in California, according to the department.
The USDA has been working to develop a way to grow and harvest more yams.
In 2016, the agency proposed allowing the planting of up to 500 million yams per year, and that goal was put on hold.
But a report from the USDA last year found that more than 90 percent of the yams planted in the U., California, Arizona, New Mexico, and Texas are not eligible for the program.
The report also found that less than 5 percent of California yams were growing well enough to be harvested, and nearly half of Arizona’s yams didn’t qualify for harvest.
“We’re at a point where the risk of drought is growing at unprecedented rates, which means the yampers are at greater risk of drying out,” said Karen Kappel, a senior research scientist at the USDA’s National Agricultural Statistics Service.
“It’s a bit like the first Gulf War, which I think was the tipping point of the climate crisis.
We’ve got to figure out how to deal with it.”
In addition to California, other areas of the country that have suffered from drought include Arizona, Nevada, Texas, Utah, and California.
The drought in Arizona has been particularly bad.
Between January and June of this year, it received nearly 60 percent of its rainfall, according the Arizona Department of Water Resources.
The state’s agricultural department is currently forecasting that the drought will worsen in the coming months.
In a statement, the Arizona Drought Mitigation Project said that the state has experienced some severe drought conditions since 2016, but that the damage is mostly temporary.
“The worst of the drought is behind us, and our efforts are being focused on restoring some of the land and water that was lost to drought, while continuing to develop and maintain a resilient agriculture system,” the statement read.
“At the same time, we continue to fight for water for farmers and ranchers in Arizona, as well as for other farmers and farmers in the Southwest, to be able to feed themselves and their families and for families in the rural West to be healthy and well-fed.”
In the past year, drought has affected a significant portion of the world’s food supply.
In Europe, the crop has been hit hard by the Mediterranean climate and by severe droughts in the United States.
The drought in California has been especially harsh, particularly in the south, where the crop tends to be planted closer to the equator.
The Trump administration has announced a $4 billion investment in drought relief efforts in California.
But the announcement came after Congress passed a package of measures last year to help farmers.
