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.”

Owners of mobile home park destroyed in the Palisades fire say they’re finally clearing the debris
Former residents of the Palisades Bowl Mobile Home Estates, a roughly 170-unit mobile home park completely destroyed in the Palisades fire, received a notice Dec. 23 from park owners saying debris removal would start as early as Jan. 2.
The Bowl is the largest of only a handful of properties in the Palisades still littered with debris nearly a year after the fire. It’s left the Bowl’s former residents, who described the park as a “slice of paradise,” stuck in limbo.
The email notice, which was reviewed by The Times, instructed residents to remove any burnt cars from their lots as quickly as possible, since contractors cannot dispose of vehicles without possessing the title. It followed months of near silence from the owners.
“The day before Christmas Eve … it triggers everybody and throws everybody upside down,” said Jon Brown, who lived in the Bowl for 10 years and now helps lead the fight for the residents’ right to return home. “Am I liable if I can’t get this done right now? Between Christmas and New Year’s? It’s just the most obnoxious, disgusting behavior.”
Brown is not optimistic the owners will follow through. “They’ve said things like this before over the years with a bunch of different things,” he said, “and then they find some reason not to do it.”
Earlier this year, the Federal Emergency Management Agency denied requests from the city and the Bowl’s owners to include the park in the U.S. Army Corps of Engineers cleanup program, which FEMA said was focused on residential lots, not commercial properties. In a letter, FEMA argued it could not trust the owners of the Bowl to preserve the beachfront property as affordable housing.

The Bowl, which began as a Methodist camp in the 1890s, was purchased by Edward Biggs, a Northern California real estate mogul, in 2005 and split between his first and second wives after his death in 2021. The family has a history of failing to perform routine maintenance and seeking to redevelop the park into a more lucrative resort community.
After FEMA’s rejection, the owners failed to meet the City of L.A.’s debris removal deadlines. In October, the city’s Board of Building and Safety Commissioners declared the park a public nuisance alongside seven other properties, giving the city the authority to complete the debris removal itself and charge the owners the bill.
But the city has yet to find funds to front the work, which is expected to cost millions.
On Dec. 10, City Councilmember Traci Park filed a motion that would order the city to come up with a cost estimate for debris removal and identify funding sources within the city. It would also instruct the city attorney’s office to explore using criminal prosecution to address the uncleared properties.
The Department of Building and Safety did not immediately respond to requests for comment.
Despite the recent movement on debris removal, residents of the Palisades Bowl still have a long road ahead.
On Wednesday, numerous burnt out vehicles still remained at the Pacific Palisades Bowl Mobile Estates. The owners instructed residents they must get them removed as quickly as possible.

In mobile home parks, tenants lease their spaces from the landowners but own the homes placed on the land. Before residents can start rebuilding, the Bowl’s owners need to replace or repair the foundations for the homes; fix any damage to the roads, utilities and retaining walls; and rebuild facilities like the community center and pool.
The owners have not responded to multiple requests for comment, but in February, Colby Biggs, Edward Biggs’ grandson, told CalMatters that “If we have to go invest $100 million to rebuild the park and we’re not able to recoup that in some fashion, then it’s not likely we will rebuild the park.”
Mobile home law experts and many residents doubt that the Biggs family would be able to convert the rent-controlled mobile home park into something else under existing law. The most realistic option, should the Biggs decide against rebuilding, would be to sell the park to another owner — or directly to the residents, a course of action the residents have been actively pursuing.
The lack of communication and action from the owners has nonetheless left the Bowl’s eclectic former community of artists, teachers, surfers, first responders and retirees in limbo.
Many are running out of insurance money for temporary housing and remain unsure whether they’ll ever be able to move back.

Commentary: ‘Stop exercising, you’re killing yourself.’ Not really, but try more nurture, less torture in 2026
One day my left foot hurt for no good reason. I stood up to shake off the pain and tweaked my right Achilles tendon, so I headed for the medicine cabinet, bent over like an ape because of a stiff back.
Actually, I lied.
It wasn’t one day. It’s pretty much every day.
None of this is severe or serious, and I’m not complaining at the age of 72. I’m just wondering.
Are my exercise routines, which were meant to keep me from falling apart, slowing my demise, or accelerating it?
What better time than the start of a new year to get an answer? In one poll, the top New Year’s resolution for 2026 is exercising more. Also among the top six resolutions are eating healthier, improving physical health and losing weight, so good luck to all you dreamers, and I hope you last longer than I have with similar resolutions.
Instead of a resolution, I have a goal, which is to find a sweet spot — if there is one — between exercise and pain.
Maybe I’m asking too much. I’ve had two partial knee replacements, I’ve got a torn posterior cruciate ligament, a scar tissue knob on a frayed Achilles tendon, a hideously pronated left foot, a right shoulder that feels like it needs an oil change, and a pacemaker that keeps on ticking.
But I decided to get some expert advice that might be useful for anyone who has entered this glorious phase of life in which it’s possible to pull a muscle while taking a nap, or pinch a nerve in your neck while brushing your teeth.
And I knew just whom to call.
Cedars-Sinai orthopedic surgeon Robert Klapper hosts an ESPN radio show called “Weekend Warrior.” This lab-coated Renaissance man, a surfer and sculptor in his spare time, also weighs in regularly on the radio with “Klapper Vision” — clear-eyed takes on all manner of twisted, pulled and broken body parts suffered by elite athletes and banged-up buzzards like me.
On “Weekend Warrior,” Klapper might be talking about knee replacement surgery one minute, segue to Michelangelo’s rendering of the human form, and then insist that a sandwich is not a sandwich without peperoncini. It isn’t necessarily all connected, but it doesn’t matter.
When I emailed Klapper about my aches and pains, he responded immediately to say he’s written one book on hips, another on knees and a third one is in the works with the following title:
“Stop Exercising, You’re Killing Yourself.”
No, he’s not saying you should never get off the sofa. In a phone conversation and later at his office, Klapper said the subtitle is going to be, “Let Me Explain.” He’s making a point about what kind of exercise is harmful and what kind is helpful, particularly for people in my age group.

My daily routine, I told him, involves a two-mile morning walk with my dog followed by 30 minutes of swimming laps or riding a stationary bike.
So far, so good.
But I also play pickleball twice a week.
“Listen, I make a living from pickleball now,” Klapper said. “Exercise is wonderful, but it comes in two flavors.”
One is nurturing, which he calls “agercise” for my demographic.
The other is abusive, and one of Klapper’s examples is pickleball. With all its starts and stops, twists and turns, reaches and lunges, pickleball is busting the Medicare bank, with a few hundred million dollars’ worth of injuries each year.
I know. The game looks pretty low key, although it was recently banned in Carmel-by-the-Sea because of all the racket. I had no idea, when I first picked up a paddle, that there’d be so much ice and ibuprofen involved, not to mention the killer stares from retirees itching for a chance to drill you in the sternum with a hot laser.
“This is a sport which has the adrenaline rushing in every 50-year-old, 60-year-old, 80-year-old,” Klapper told me in his office, which is the starting point in his joint replacement factory. The walls are covered with photos of star athletes and A-list Hollywood celebrities he’s operated on.
“I see these patients, but they’re not coming to me with acute injuries. They didn’t snap their Achilles tendon … like they do in tennis. They’re not snapping their ACL like they are in pickup basketball,” Klapper said. “They’re coming to me saying, ‘My shoulder is killing me, my knee is killing me.’ ”
Pickleball has obvious conditioning benefits for every age group. But it can also worsen arthritis and accelerate joint degeneration, Klapper said, particularly for addicts who play several times a week.
Not that he’s the first MD to suggest that as you age, walking, cycling and swimming are easier on your body than higher-impact activities. As one doctor said in an AARP article on joint care and the benefits of healthy eating, watching your weight and staying active, “the worst thing you can do with osteoarthritis after 50 is be sedentary.”
Still, I thought Klapper might tell me to stop pickling, but he didn’t.
“Pickleball is more than a sport to you … and all of your compadres,” he said. “It’s mental. You need it because of the stress. The world’s falling apart.… I want you to play it, but I want you to do the nurturing exercises so you can do the abuse.”
There’s no fountain of youth, Klapper said, but the closest thing is a swimming pool.
OK, but I already swim three times a week.

Klapper had different ideas.
“You need to be walking forward and backwards for half an hour,” he said. Do that three times a week, he told me, and ride a stationary bike three times.
Why the water walking?
“We as humans take over a million steps a year. Forget pickleball, just in … daily living,” Klapper said, so I’m well beyond 72 million steps.
“Think about that,” he said.
Do I have to?
Water walking will develop muscles and joints without the stress of my full weight, and that could “optimize” my pickleball durability and general fitness, Klapper said. Buoyancy and the touch of water on skin are magic, he said, but there’s science involved too.
“It’s hard to move your arms and legs and your body through water, and yet it’s unloading the joint,” Klapper said. “And finally — and this is the real X factor — when you close your eyes and straighten your elbow and bend your elbow, straighten your knee and bend your knee … your brain knows where your limbs are in space.”
This is called proprioception, Klapper said. Receptors in your skin, muscles, ligaments and tendons send messages to your brain, leading to better balance, coordination and agility and potentially reducing risk of injury.
There are lots of exercises for sharpening proprioception, but the surfing doctor is partial to bodies of water. At my age, he said, my proprioception “batteries are running low,” but I can recharge them with a short break from pickleball and a focus on the pool.
“You can’t guarantee anything in life and medicine,” Klapper said. “But I guarantee you, a month into it, you’re going to feel so much better than you do at this moment.”
It’s worth a try, and I’ll let you know how it goes.
In the pool and on the court.
