There’s A Lot At Stake In The Weekly U.S. Drought Map — National Public Radio

US Drought Monitor December 25, 2018.

From National Public Radio (Grace Hood):

Crippling drought this year has caused more than $1 billion in damage. As it has played out, anyone affected by the drought or trying to manage it has turned to a once obscure map that has become key to understanding what’s happening: the U.S. Drought Monitor.

That includes water planners who decide resource allotments. Farmers who need water for their livelihood. Federal bureaucrats who use the map to calculate aid for the Livestock Forage Disaster Program.

And then there are citizen scientists like Dave Kitts outside of Sante Fe, N.M.

“I think it’s a little obsessive, but I check it every Thursday,” says Kitts, who has lived on the same 2-acre spread in New Mexico for decades. Dry years like this past one can crust the soil and kill his pinyon trees.

“It’s just upsetting and depressing to me,” he says. “And when it moves the other direction, it definitely lifts my spirits.”

Scientist Mark Svoboda started the drought map 20 years ago, when Congress took an interest after drought struck Washington, D.C. He directs the National Drought Mitigation Center at the University of Nebraska, Lincoln.

“We’re covering everything,” he says, “from groundwater, stream flow, temperature.”

In bad drought years like this one, the map has patches of crayon yellow, orange and red that show the levels of drought. Right now, there’s a deep crimson bull’s-eye in the hardest-hit area of the southwest, where Colorado borders Utah, Arizona and New Mexico…

A mix of art, science and farmer wisdom

The Drought Monitor map is updated weekly, often taking into account input from hundreds of people — in addition to scientists. Ranchers and farmers from across the country also send missives to state and national offices, making the map a mix of art, science and farmer wisdom. But it starts with recommendations from state climatologists on any potential changes.

Assistant Colorado Climatologist Becky Bolinger says she has been “feeling a little bit more hopeful” about recent rain and snow, as it could mean a smaller crimson blotch in the southwest. At least that’s what her data suggested.

But Bolinger wanted more context, so she asked for field reports from Colorado’s farmers and ranchers.
