– Two scientific agencies in the Department of Agriculture will move from Washington to the greater Kansas City region, USDA announced Thursday, despite strong resistance to the plan.

The Twin Cities had been considered as a possible home for the agencies.

Nearly 550 positions at the Economic Research Service, a statistical agency, and the National Institute of Food and Agriculture, which funds cutting-edge agricultural science, are expected to be moved before year's end. USDA estimated the savings at $300 million over 15 years from employment and rent.

"The Kansas City Region has proven itself to be hub for all things agriculture and is a booming city in America's heartland," Agriculture Secretary Sonny Perdue said in a statement.

The news release did not identify the location of the offices. But Tim Cowden, president and chief executive of the Kansas City Area Development Council, said the agency is evaluating office property on both sides of the Kansas-Missouri border.

Perdue had unveiled a plan to relocate the two agencies in August, without specifying a site. He called the decision a cost-saving measure and said it would bring them closer to their "stakeholders" in farming regions. Initially, he also proposed placing ERS under the Office of the Chief Economist but that was not part of the final plan, according to a letter the secretary sent employees on Thursday.

Scientists across the country rely on NIFA grants to study topics ranging from climate change and crop genetics to farmland drones. ERS produces statistical reports that influence decisions in corporate boardrooms and in state and federal capitals.

Republican senators representing Missouri and Kansas welcomed Thursday's announcement.

"We're home to some of the hardest working farmers in the country, so this is a fantastic decision by the USDA," Sen. Josh Hawley, R-Mo., said in a statement.

NIFA and ERS workers will join nearly 5,000 other USDA employees in Kansas City, said Cowden, whose group proposed the region to USDA last year.

"We're within 300 miles of 13 land-grant universities," said Kimberly Young, president of the Kansas City Animal Health Corridor, a development council initiative. The area is an "epicenter" of the animal health industry, Young said, with more than 300 such companies nearby.

But current employees of the two agencies, mostly Democratic lawmakers and a bipartisan coalition of former USDA leaders warned that the move, more than 900 miles from Washington, would devastate the two agencies.

"This is not just a change of address," said Jack Payne, University of Florida's senior vice president for agriculture. "It cuts NIFA off from the collaboration with other federal funding agencies in D.C. that are its major partners."

NIFA unionized earlier this week, and ERS unionized in May in the face of the decision. Union officials have promised to fight the move.

"The announcement today should be met with great skepticism that Secretary Perdue has the best interests of either federal employees or American agriculture in mind," said Kevin Hunt, acting vice president of American Federation of Government Employees Local 3403, which represents ERS employees.

Gale Buchanan, USDA chief scientist under President George W. Bush, and Catherine Woteki, chief scientist in the Obama administration, predicted the relocation would set ERS back "five to 10 years" due to a loss of specialized employees, as they wrote in a 2018 letter to Congress signed by dozens of agricultural leaders.

"There isn't a plan in place for how to manage this," Woteki told the Washington Post. The offices, which together employ about 700 people when fully staffed, are roughly two-thirds the size they were during the Obama administration.

Workloads have ballooned as ERS employees have quit at double the normal rate since October, the Post reported. Acting officials have filled several vacant ERS leadership positions.

USDA lacks a chief scientist, who oversees ERS, NIFA and other USDA research offices.

Trump's first nominee, radio host Sam Clovis, withdrew from consideration over his ties to the investigation of Russia's influence on the 2016 election.

Sen. Christopher Van Hollen, D-Md., placed a hold on Trump's second nominee, former Dow pesticide executive Scott Hutchins, because the senator opposes the relocation, said Bridgett Frey, a spokeswoman for Van Hollen.
