Dickson Despommier, Who Championed Farming in Skyscrapers, Dies at 84
Dickson Despommier, a microbiologist who proposed that cities should grow food in high-rises, popularizing the term “vertical farming” — an idea that crossed over from the realm of the purely fanciful to become a reality around the globe — died on Feb. 7 in Manhattan. He was 84.
His wife, Marlene Bloom, confirmed the death, in a hospital. He lived in Fort Lee, N.J.
Dr. Despommier (pronounced de-POM-ee-yay), who was a professor for 38 years at Columbia’s School of Public Health, specialized in parasitic diseases, but he gained far wider influence as a guru of vertical farming.
In 2001, he and students in a medical ecology class designed a 30-story building that theoretically could grow food for 50,000 people. Some 100 varieties of fruits and vegetables would be grown on upper floors, with chickens housed lower down. Fish would feed on plant waste.
Dr. Despommier argued that vertical farms would use 70 to 90 percent less water than traditional farms, allowing agricultural land to return to a natural state and helping to remediate climate change. He evangelized at TEDx talks and in a book, “The Vertical Farm: Feeding the World in the 21st Century.”
“When my book came out, in 2010, there were no functioning vertical farms that I was aware of,” he told The New Yorker several years later. “By the time I published a revised edition in 2011, vertical farms had been built in England, Holland, Japan and Korea.”
Tech investors poured money into vertical farming. The operations generally substituted indoor LED lights for sunlight and used watering systems that spritzed plant roots — no soil needed. The farms sprouted in places as varied as downtown Newark and Dubai, on the Persian Gulf.
The Guardian estimated that there were more than 2,000 vertical farms in the U.S. in 2022, raising vegetables and fruits in stacked trays or long columns, some several stories high, some tended by robots. That year, Walmart announced that it would harvest salad greens from a vertical farm in Compton, Calif., to be run by a company named Plenty.
More recently, the industry has stumbled. High interest rates and energy costs have caused many operations to close or declare bankruptcy. They include the one in Compton and the one in Newark, AeroFarms, which The New Yorker featured prominently in its article about Dr. Despommier in 2017. A company with farms in three Eastern states, Bowery Farming, whose investors included Justin Timberlake and Natalie Portman and which was once valued at $2.3 billion, shut down last year.
Critics questioned if vertical farming really lowers carbon emissions and called it a fad. Others said the industry is merely going through a shakeout and will endure.
Dickson Donald Despommier was born on June 5, 1940, in New Orleans to Roland and Beverly (Wood) Despommier. His father was an accountant for a shipping line. His parents divorced when Dickson was young.
He received a B.S. in biology from Fairleigh Dickinson University in 1962, an M.S. in medical parasitology from Columbia in 1964 and a Ph.D. in microbiology from the University of Notre Dame in 1967.
Dr. Despommier joined Columbia’s faculty in 1971 as an assistant professor of microbiology. He taught a required course in parasitic diseases to second-year medical students for three decades. His research focused on tropical diseases; he was co-author of a textbook, “Parasitic Diseases,” and a director of the website “Parasites Without Borders.”
Besides his wife, he is survived by his sister, Duane Despommier Kuykendall; his sons, Bruce and Bradley; a stepdaughter, Molly Bloom; a stepson, Michael Goodwin; four grandchildren; and three great-grandchildren. An earlier marriage, to Judith Forman, ended in divorce.
The idea of vertical farming emerged when students told Dr. Despommier in 2000 that they were bored with his course on medical ecology. He redirected the semester by posing a question, “What will the world be like in 2050?” and a follow-up question, “What would you like the world to be like in 2050?”
The discussion focused on how densely crowded the planet would be in 50 years and how food would have to be grown then with less water and less pollution from chemical fertilizers. Students said New York City should source all its food from close by. They suggested using the city’s rooftops for agriculture. But then they calculated that if every rooftop in all five boroughs were turned into a garden, the growing acreage would feed only about 2 percent of the population.
Dr. Despommier then thought of raising crops in glass and steel skyscrapers, with plants stacked on multiple levels, just like their human inhabitants. He continued to refine designs with each year’s class of ecology students. In 2001, he adopted the term vertical farming.
After he appeared on the Comedy Central late-night show “The Colbert Report” in 2008 to discuss his eggplants-in-the-sky idea, traffic to his website shot up to 400,000 visitors overnight.
Many of the start-ups that turned Dr. Despommier’s vision into a reality built vertical farms that were only two or three stories high, compared with the 30-story behemoths he had proposed. One was attached to a parking garage in Jackson, Wyo. Others were housed in shipping crates.
But the idea traversed the globe, with a nonprofit, the Association for Vertical Farming, starting up in Germany in 2013.
All along, skeptics questioned whether the cost and the carbon footprint of indoor farming was an improvement over the traditional kind practiced by humanity for some 12,000 years.
“It’s such an appealing idea — ‘Press floor 10 for lettuce’ — that people picked up on it right away,” Bruce Bugbee, a professor of crop physiology at Utah State University, told The New York Times in 2016. “The fundamental problem is that plants need a lot of light. It’s free outside. If we’re going to do it inside, it will require the burning of a lot of fossil fuels.”
The industry shakeout has been brutal, with the editor of the news site Vertical Farming Today declaring in 2023 that venture capital investments in vertical farming had fallen by about 90 percent.
Unfazed, Dr. Despommier kept brainstorming about how modern life could thrive in the face of a dangerously changing climate. In his last book, “The New City: How to Build Our Sustainable Urban Future” (2023), he proposed that cities henceforth be built of wood.
The carbon footprint of making concrete and steel, he explained, is enormous, whereas wood is a carbon sink — trees absorb carbon from the air as they grow — and new technologies for engineering timbers allowed very tall buildings to be built.
“It sounds like we’ll be using up all the wood,” he said last year, “but the fact is that, if vertical farming succeeds, there’ll be a lot more land to grow trees.”

Trump administration declares ‘war on sugar’ in overhaul of food guidelines
The Trump administration announced a major overhaul of American nutrition guidelines Wednesday, replacing the old, carbohydrate-heavy food pyramid with one that prioritizes protein, healthy fats and whole grains.
“Our government declares war on added sugar,” Health and Human Services Secretary Robert F. Kennedy Jr. said in a White House press conference announcing the changes. “We are ending the war on saturated fats.”
“If a foreign adversary sought to destroy the health of our children, to cripple our economy, to weaken our national security, there would be no better strategy than to addict us to ultra-processed foods,” Kennedy said.
Improving U.S. eating habits and the availability of nutritious foods is an issue with broad bipartisan support, and has been a long-standing goal of Kennedy’s Make America Healthy Again movement.
During the press conference, he acknowledged both the American Medical Association and the American Assn. of Pediatrics for partnering on the new guidelines — two organizations that earlier this week condemned the administration’s decision to slash the number of diseases that U.S. children are vaccinated against.
“The American Medical Association applauds the administration’s new Dietary Guidelines for spotlighting the highly processed foods, sugar-sweetened beverages, and excess sodium that fuel heart disease, diabetes, obesity, and other chronic illnesses,” AMA president Bobby Mukkamala said in a statement.

Contributor: With high deductibles, even the insured are functionally uninsured
I recently saw a patient complaining of shortness of breath and a persistent cough. Worried he was developing pneumonia, I ordered a chest X-ray — a standard diagnostic tool. He refused. He hadn’t met his $3,000 deductible yet, and so his insurance would have required him to pay much or all of the cost for that scan. He assured me he would call if he got worse.
For him, the X-ray wasn’t a medical necessity, but it would have been a financial shock he couldn’t absorb. He chose to gamble on a cough, and five days later, he lost — ending up in the ICU with bilateral pneumonia. He survived, but the cost of his “savings” was a nearly fatal hospital stay and a bill that will quite likely bankrupt him. He is lucky he won’t be one of the 55,000 Americans to die from pneumonia each year.
As a physician associate in primary care, I serve as a frontline witness to this failure of the American approach to insurance. Medical professionals are taught that the barrier to health is biology: bacteria, viruses, genetics. But increasingly, the barrier is a policy framework that pressures insured Americans to gamble with their lives. High-deductible health plans seem affordable because their monthly premiums are lower than other plans’, but they create perverse incentives by discouraging patients from seeking and accepting diagnostics and treatments — sometimes turning minor, treatable issues into expensive, life-threatening emergencies. My patient’s gamble with his lungs is a microcosm of the much larger gamble we are taking with the American public.
The economic theory underpinning these high deductibles is known as “skin in the game.” The idea is that if patients are responsible for the first few thousand dollars of their care, they will become savvy consumers, shopping around for the best value and driving down healthcare costs.
But this logic collapses in the exam room. Healthcare is not a consumer good like a television or a used car. My patient was not in a position to “shop around” for a cheaper X-ray, nor was he qualified to determine if his cough was benign or deadly. The “skin in the game” theory assumes a level of medical literacy and market transparency that simply doesn’t exist in a moment of crisis. You can compare the specs of two SUVs; you cannot “shop around” for a life-saving diagnostic while gasping for air.
A 2025 poll from the Kaiser Family Foundation points to this reality, finding that up to 38% of insured American adults say they skipped or postponed necessary healthcare or medications in the past 12 months because of cost. In the same poll, 42% of those who skipped care admitted their health problem worsened as a result.
This self-inflicted public health crisis is set to deteriorate further. The Congressional Budget Office estimates roughly 15 million people will lose health coverage and become uninsured by 2034 because of Medicaid and Affordable Care Act marketplace cuts. That is without mentioning the millions more who will see their monthly premiums more than double if premium tax credits are allowed to expire. If that happens, not only will millions become uninsured but also millions more will downgrade to “bronze” plans with huge deductibles just to keep their premiums affordable. We are about to flood the system with “insured but functionally uninsured” patients.
I see the human cost of this “functional uninsurance” every week. These are patients who technically have coverage but are terrified to use it because their deductibles are so large they may exceed the individuals’ available cash or credit — or even their net worth. This creates a dangerous paradox: Americans are paying hundreds of dollars a month for a card in their wallet they cannot afford to use. They skip the annual physical, ignore the suspicious mole and ration their insulin — all while technically insured. By the time they arrive at my clinic, their disease has often progressed to a catastrophic event, from what could have been a cheap fix.
Federal spending on healthcare should not be considered charity; it is an investment in our collective future. We cannot expect our children to reach their full potential or our workforce to remain productive if basic healthcare needs are treated as a luxury. Inaction by Congress and the current administration to solve this crisis is legislative malpractice.
In medicine, we are trained to treat the underlying disease, not just the symptoms. The skipped visits and ignored prescriptions are merely symptoms; the disease is a policy framework that views healthcare as a commodity rather than a fundamental necessity. If we allow these cuts to proceed, we are ensuring that the American workforce becomes sicker, our hospitals more overwhelmed and our economy less resilient. We are walking willingly into a public health crisis that is entirely preventable.

Ideas expressed in the piece
-
High-deductible health plans create a barrier to necessary medical care, with patients avoiding diagnostics and treatments due to out-of-pocket cost concerns[1]. Research shows that 38% of insured American adults skipped or postponed necessary healthcare or medications in the past 12 months because of cost, with 42% reporting their health worsened as a result[1].
-
The economic theory of “skin in the game”—which assumes patients will shop around for better healthcare values if they have financial responsibility—fails in medical practice because patients lack the medical literacy to make informed decisions in moments of crisis and cannot realistically compare pricing for emergency or diagnostic services[1].
-
Rising deductibles are pushing enrollees toward bronze plans with deductibles averaging $7,476 in 2026, up from the average silver plan deductible of $5,304[1][4]. In California’s Covered California program, bronze plan enrollment has surged to more than one-third of new enrollees in 2026, compared to typically one in five[1].
-
Expiring federal premium tax credits will more than double out-of-pocket premiums for ACA marketplace enrollees in 2026, creating an expected 75% increase in average out-of-pocket premium payments[5]. This will force millions to either drop coverage or downgrade to bronze plans with massive deductibles, creating a population of “insured but functionally uninsured” people[1].
-
High-deductible plans pose particular dangers for patients with chronic conditions, with studies showing adults with diabetes involuntarily switched to high-deductible plans face 11% higher risk of hospitalization for heart attacks, 15% higher risk for strokes, and more than double the likelihood of blindness or end-stage kidney disease[4].
Different views on the topic
-
Expanding access to health savings accounts paired with bronze and catastrophic plans offers tax advantages that allow higher-income individuals to set aside tax-deductible contributions for qualified medical expenses, potentially offsetting higher out-of-pocket costs through strategic planning[3].
-
Employers and insurers emphasize that offering multiple plan options with varying deductibles and premiums enables employees to select plans matching their individual needs and healthcare usage patterns, allowing those who rarely use healthcare to save money through lower premiums[2]. Large employers increasingly offer three or more medical plan choices, with the expectation that employees choosing the right plan can unlock savings[2].
-
The expansion of catastrophic plans with streamlined enrollment processes and automatic display on HealthCare.gov is intended to make affordable coverage more accessible for certain income groups, particularly those above 400% of federal poverty level who lose subsidies[3].
-
Rising healthcare costs, including specialty drugs and new high-cost cell and gene therapies, are significant drivers requiring premium increases regardless of plan design[5]. Some insurers are managing affordability by discontinuing costly coverage—such as GLP-1 weight-loss medications—to reduce premium rate increases for broader plan members[5].

Trump administration slashes number of diseases U.S. children will be regularly vaccinated against
The U.S. Department of Health and Human Services announced sweeping changes to the pediatric vaccine schedule on Monday, sharply cutting the number of diseases U.S. children will be regularly immunized against.
Under the new guidelines, the U.S. still recommends that all children be vaccinated against measles, mumps, rubella, polio, pertussis, tetanus, diphtheria, Haemophilus influenzae type B (Hib), pneumococcal disease, human papillomavirus (HPV) and varicella, better known as chickenpox.
Vaccines for all other diseases will now fall into one of two categories: recommended only for specific high-risk groups, or available through “shared clinical decision-making” — the administration’s preferred term for “optional.”
These include immunizations for hepatitis A and B, rotavirus, respiratory syncytial virus (RSV), bacterial meningitis, influenza and COVID-19. All these shots were previously recommended for all children.
Insurance companies will still be required to fully cover all childhood vaccines on the CDC schedule, including those now designated as optional, according to the Department of Health and Human Services.
Health Secretary Robert F. Kennedy Jr., a longtime vaccine critic, said in a statement that the new schedule “protects children, respects families, and rebuilds trust in public health.”
But pediatricians and public health officials widely condemned the shift, saying that it would lead to more uncertainty for patients and a resurgence of diseases that had been under control.
“The decision to weaken the childhood immunization schedule is misguided and dangerous,” said Dr. René Bravo, a pediatrician and president of the California Medical Assn. “Today’s decision undermines decades of evidence-based public health policy and sends a deeply confusing message to families at a time when vaccine confidence is already under strain.”
The American Academy of Pediatrics condemned the changes as “dangerous and unnecessary,” and said that it will continue to publish its own schedule of recommended immunizations. In September, California, Oregon, Washington and Hawaii announced that those four states would follow an independent immunization schedule based on recommendations from the AAP and other medical groups.
The federal changes have been anticipated since December, when President Trump signed a presidential memorandum directing the health department to update the pediatric vaccine schedule “to align with such scientific evidence and best practices from peer, developed countries.”
The new U.S. vaccination guidelines are much closer to those of Denmark, which routinely vaccinates its children against only 10 diseases.
As doctors and public health experts have pointed out, Denmark also has a robust system of government-funded universal healthcare, a smaller and more homogenous population, and a different disease burden.
“The vaccines that are recommended in any particular country reflect the diseases that are prevalent in that country,” said Dr. Kelly Gebo, dean of the Milken Institute School of Public Health at George Washington University. “Just because one country has a vaccine schedule that is perfectly reasonable for that country, it may not be at all reasonable” elsewhere.
Almost every pregnant woman in Denmark is screened for hepatitis B, for example. In the U.S., less than 85% of pregnant women are screened for the disease.
Instead, the U.S. has relied on universal vaccination to protect children whose mothers don’t receive adequate care during pregnancy. Hepatitis B has been nearly eliminated in the U.S. since the vaccine was introduced in 1991. Last month, a panel of Kennedy appointees voted to drop the CDC’s decades-old recommendation that all newborns be vaccinated against the disease at birth.
“Viruses and bacteria that were under control are being set free on our most vulnerable,” said Dr. James Alwine, a virologist and member of the nonprofit advocacy group Defend Public Health. “It may take one or two years for the tragic consequences to become clear, but this is like asking farmers in North Dakota to grow pineapples. It won’t work and can’t end well.”
