(Press-News.org) ITHACA, N.Y. – Climate change and flagging investment in research and development has U.S. agriculture facing its first productivity slowdown in decades. A new study estimates the public sector investment needed to reverse course.
In the paper, published in the Proceedings of the National Academy of Sciences, researchers model both the dampening effects of climate change on U.S. agriculture and the accelerating effects of publicly funded research and development (R&D) – and use the estimates to quantify the investment in research required to maintain agricultural productivity through 2050.
They find that a 5% to 8% per year growth in research investment is needed – an investment comparable to those made following the two world wars. Alternatively, they find that a fixed $2.2 billion to $3.8 billion per year in additional investment would also offset the climate-induced slowdown.
“What we find is that we need a very steep growth rate – but it’s not unprecedented. We’ve seen the U.S. step up in the past. We can do this, but the time is now,” said senior author Ariel Ortiz-Bobea, associate professor at Cornell and an applied economist with expertise in agricultural, environmental and energy policy.
The urgency stems from the imminent effects of climate change and because publicly funded R&D in agriculture – which is carried out at universities and research centers – takes time to impact productivity.
“It’s not like an iPhone that can be designed in California, manufactured in China and used in Ithaca,” Ortiz-Bobea said. “The research has to be done in close proximity to the people using it, and then it needs to be adopted by farmers. So, it takes time, and the longer we wait, the longer we stay on a path where we’re less productive, while other nations like China and Brazil are investing heavily in R&D.”
The current public sector investment in R&D is approximately $5 billion, with spending growing only .5% per year from 1970 to 2000 before stagnating. Ortiz-Bobea favors the more incremental investment scenario that adds 5% to 8% funding every year, for a total investment of $208 billion to $434 billion by 2050.
“The current environment is one where any public spending is seen as a waste, and obviously any use of taxpayer dollars should be assessed in a systematic way,” Ortiz-Bobea said. “But decades of research shows that agricultural research has a very high return on investment for the country.”
The alternative, Ortiz-Bobea said, is declining productivity, more government bailouts and increased reliance on other countries, as well as more environmental degradation: as farmers would need to use more land and more chemicals to increase production.

How chemistry and force etch mysterious spiral patterns on solid surfaces
2025-03-13
Key takeaways
Curiosity about a mistake that left tiny dots on a germanium wafer with evaporated metal films led to the discovery of beautiful spiral patterns etched on the surface of the semiconductor by a chemical reaction.
Further experiments showed that the patterns arise from chemical reactions that are coupled to mechanical forces through the deformation of a catalyzing agent.
The new system is the first major advance in experimental methods to study chemical pattern formation since the 1950s. Studying these complex systems will help scientists understand other natural processes, from crack formation in materials to how stress ...
Unraveling the mysteries of polycystic kidney disease
2025-03-13
OKLAHOMA CITY – Polycystic kidney disease (PKD), a family of genetic disorders that causes clusters of cysts to form on the kidney, is among the most common genetic disorders, affecting some 500,000 people in the United States. Roughly one in every 1,000 people will develop some form of cystic kidney disease during their lifetime, and nearly 40,000 Oklahomans have a chronic kidney disease, according to the Oklahoma Health Care Authority.
For many patients, dialysis – a time-consuming and costly procedure – is one of few treatment options. A 2021 study ...
Mother’s high-fat diet can cause liver stress in fetus, study shows
2025-03-13
OKLAHOMA CITY – When mothers eat a diet high in fat and sugars, their unborn babies can develop liver stress that continues into early life. A new study published in the journal Liver International sheds light on changes to the fetus’s bile acid, which affects how liver disease develops and progresses.
Bile acids typically help with digestion and absorb dietary fats in the small intestine, but when they reach excessive levels, they become toxic and can damage the liver. While the mother can detoxify the acids, the fetus lacks that ability. Bile acids may re-circulate to the mother for detoxification, but if they don’t, they build ...
Weighing in on a Mars water debate
2025-03-13
More than 3 billion years ago, Mars intermittently had liquid water on its surface. After the planet lost much of its atmosphere, however, surface water could no longer persist. The fate of Mars’ water—whether it was buried as ice, confined in deep aquifers, incorporated into minerals or dissipated into space—remains an area of ongoing research, one of particular interest to LASP Senior Research Scientist Bruce Jakosky, former principal investigator of the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission.
Last week, in a letter to the editor ...
Researchers ‘seq’ and find a way to make pig retinal cells to advance eye treatments
2025-03-13
MADISON — Inside the human eye, the retina is made up of several types of cells, including the light-sensing photoreceptors that initiate the cascade of events that lead to vision. Damage to the photoreceptors, either through degenerative disease or injury, leads to permanent vision impairment or blindness.
David Gamm, director of UW–Madison’s McPherson Eye Research Institute and professor of ophthalmology and visual sciences, says that stem cell replacement therapy using lab-grown photoreceptors ...
Re-purposed FDA-approved drug could help treat high-grade glioma
2025-03-13
High-grade glioma, an aggressive form of pediatric and adult brain cancer, is challenging to treat given the tumor location, incidence of recurrence and difficulty for drugs to cross the blood-brain barrier.
Researchers from the University of Michigan, Dana Farber Cancer Institute and the Medical University of Vienna established a collaborative team to uncover a potential new avenue to address this disease.
A study, published in Cancer Cell, shows that high-grade glioma tumor cells harboring DNA alterations in the gene PDGFRA responded to the drug avapritinib, which is already approved by the United States Food and Drug Administration to treat gastrointestinal ...

Envision a world where unmanned aircraft deliver goods to your front door and transport passengers in flying taxis, cargo planes cross continents carrying vital trade goods, and fighter jets patrol battle zones—all without a human pilot at the controls.
Those scenarios might seem a bit far-fetched now, but researchers are working diligently to develop these aircraft and ensure they operate safely. That’s why NASA has awarded a $1 million grant through its University Leadership Initiative (ULI) to a team from The University of Texas at Arlington Research ...
Mutations disrupt touch-based learning, study finds
2025-03-13
You may scarcely notice it, but much of what you do every day requires your brain to engage in perceptual learning. To safely cross an intersection or quickly retrieve something from your bag, you depend upon your brain to first assign meaning to sensory input from your eyes or fingertips.
Usually, it’s effortless.
Research from The Herbert Wertheim UF Scripps Institute for Biomedical Innovation & Technology shows a gene called Syngap1 enables touch-based perception, while certain mutations can lead to mixed signals. The research was made possible through grants from the National Institute of Mental Health and the National Institute ...
