Erin McGuire spent years cultivating fruits and vegetables like onions, peppers and tomatoes as a scientist and later director of a lab at the University of California-Davis. She collaborated with hundreds of people to breed drought-resistant varieties, develop new ways to cool fresh produce and find ways to make more money for small farmers at home and overseas.
Then the funding stopped.
Her lab, and by extension many of its overseas partners, were backed financially by the United States Agency for International Development, which Trump's administration . Just before it was time to collect data that was two years in the making, her team received a stop-work order. She had to lay off her whole team. Soon she was laid off, too.

It’s a serious issue for farmers who depend on new innovations to keep their businesses afloat, the next generation of scientists and eventually consumers who buy food.

Trump administration hastens funding cuts
As the Trump administration pauses and shutters research programs funded by the Environmental Protection Agency, USDA and other agencies, Ortiz-Bobea and other experts saw field trials stopped, postdoctoral positions eliminated and a gap forming between the reality of climate change and the tools farmers have to deal with it.
The EPA declined to comment, and the USDA and USAID did not respond to Associated Press queries.
Ortiz-Bobea and his team quantified overall U.S. agricultural productivity, estimated how much it would be slowed by climate change in coming years and calculated how much money would need to be invested in research and development to counteract that slowdown.
Think of it like riding a bike into a headwind, Ortiz-Bobea said. To maintain the same speed, you have to pedal harder; in this case, R&D can be that extra push.

Some countries are heading in that direction. China spends almost twice as much as the U.S. on agricultural research and increased its research investments by five times since 2000, Omanjana Goswami, a scientist with the Food and Environment team at the Union of Concerned Scientists,Ìýwrote in an email.
U.S. spending cutbacks also shuttered agricultural research across almost all of the Feed the Future Innovation Labs, of which McGuire's was one. Those 17 labs across 13 universities focused on food security, technical agriculture research, policy and various aspects of climate change. The stop-work orders at those labs not only disappointed researchers, but made much of their work useless.
“There are many, many millions of dollars of expenditure that will generate nothing now because the work couldn’t be finished,†said David Tschirley, a professor who was directing another one of those programs, the Innovation Lab for Food Security Policy Research, Capacity and Influence at Michigan State University, since 2019.

Finding new funding for agricultural research
Some researchers hope other sources of funding can fill the gaps.
“That’s where private sector could really step up,†said Swati Hegde, a scientist in the Food, Land, and Water Program at the World Resources Institute.
From an agricultural point of view, climate change is “really scary,†with larger and larger regions exposed to temperatures above healthy growing conditions for many crops, said Bill Anderson, CEO of Bayer, a multinational biotechnology and pharmaceutical company that invested nearly $3 billion in agricultural research and development last year.
However, private companies have their own constraints on R&D investment, and he said Bayer can't invest as much as it would like in that area.
“I don’t think that private industry can replicate" how federal funding typically supports early stage, speculative science, he said, “because the economics don't really work.†He added that industry tends to be better suited to back ideas that already were validated.
Jude Addo-Chidie, a Ph.D. student in agronomy at Purdue University, places a probe in soil July 12, 2023, as he takes samples from a corn field at the Southeast-Purdue Agricultural Center in Butlerville, Ind. Public funding for agricultural research in the U.S. has been declining, a process President Donald Trump has rapidly accelerated by freezing or pausing support for a variety of research programs.
Goswami also expressed concerns that private research funding isn't as trackable and transparent as public funding. Others said even sizeable investments from companies don't give anywhere near enough money to match government funding.
The full impact may not be apparent for many years, and the damage won't easily be repaired. Experts think it will be a blow in other countries where climate change is already decimating yields, driving hunger and conflict.
“I really worry that if we don’t really look at the global food situation, we will have a disaster,†said David Zilberman, a professor at UC Berkeley who won a Wolf Prize in 2019 for his work on agriculture.
