Dickson Despommier's 'The Vertical Farm' Touts Visionary Urban Agriculture Methods

DETROIT — A new book by an urban agriculture visionary aims to change the way people think about farming, offering a look into a future where city skyscrapers – not rural fields – produce the world's food.

In "The Vertical Farm," Dickson Despommier challenges the notion that plants should be grown in soil, advocating for developing and investing in big projects using hydroponic greenhouses and other indoor growing technology in cities.

The goal is to provide safe, fresh food around the globe in a way Despommier says is impossible with modern farming. He acknowledges that getting to that future might be expensive, but he considers it a challenge akin to the space race.

"There is nothing stopping us from doing that any more than there was nothing stopping us from going to the moon," the 70-year-old Despommier said in a recent interview about the book, his third, released this month by Thomas Dunne Books/St. Martin's Press.

Despommier (pronounced 'DAY-palm-YAY) developed his ideas as a professor of public health in environmental health sciences at Columbia University. He and his students spent the past decade studying ways to incorporate agriculture into urban areas and developing plans for high-rise farms.

Despommier, who retired in January, has been a leading voice promoting the possibility that urban agriculture could be more than community plots on vacant lots in cities like New York and Detroit. His ideas tend to be grander in scale – and more enmeshed in new technology – than those of others in the field.

He envisions growing crops in indoor areas more concentrated than farm fields, and herbicides, pesticides and fertilizers wouldn't be used. Towers could be built just for growing, or empty buildings could be converted.

In its ultimate form, Despommier envisions a system for farming that would use energy from burning human waste, for example, and biofuels from the vertical farm itself to help power extremely energy efficient grow lights. Fish and poultry could be raised in the buildings, along with fruits and vegetables.

Some of those steps are taking place already on a smaller, lower-tech scale. In Milwaukee, for example, former pro basketball player and urban farmer Will Allen has created a self-sustaining system of fish and vegetable farming.

And companies such as Cornwall, England-based Valcent Products Ltd. make systems to grow indoors in warehouses or other buildings. Valcent's CEO Chris Bradford credits Despommier for pushing the boundaries of what might be possible.

"The concept grasps people's imagination and they start thinking about whether urban farming is a practical solution," said Bradford, who expects his company's VertiCrop system to begin being used in the U.S. in early 2011.

Despommier acknowledges that the vision presented in the book is far off. Or as environmental justice activist Majora Carter writes in the book's foreword: "If the skyscraper farm is like a 747 jetliner, we are now at the stage of the Wright Brothers."

But, Despommier notes, that's still a point from which to start.

The book includes an overview of how the farming developed, as well as laying out ideas for what vertical farms could become. Despommier advocates investing hundreds of millions of dollars in federal money in research at urban agricultural centers around the country where prototypes could be built and ideas hashed out.

"What could be more worth spending money on, in my view, than to try to get everybody safe food and water?" Despommier asked.

Well, it makes for good eye candy, but as far as growing wholesome food I'd rather put more faith on a flat piece of land 10 miles outside of town. Land may be a finite resource, so are rare earth metals, which do you think is more of a limiting factor in Texas?

The last thing we need to do to generate more food in a sustainable fashion is "go up". We have plenty of land, we're just not using it effectively. We're paying farmers not to farm land for the sake of creating wildlife habitat while ranchers in New Mexico are raising rotationally grazed cattle on land that has more biodiversity than the neighboring public reserves. Architects aren't going to solve the world's food and farm problems, it's going to take an army of farmer ecologists.

So it'll require more people to live out in the countryside, that's fine, not everyone living in the city wants to be there anyway.

**He envisions growing crops in indoor areas... and fertilizers wouldn't be used**

Uh huh. Magic. I envision magic beans. Lets just forget the fungicides that would be needed also.

In general I think this is a wonderful idea. But I have to wonder what makes someone think that people will be willing to work for 10 to 12 bucks per hour at one of these vertical grows, when they are unwilling to work for 10 to 12 bucks at our current horizontal farms?

Congratulations, you're a naysayer on inevitable technology. We've always had them and always will despite our ongoing technological advancements.

They like to pop up on every article about electric cars too and offer up reasons while it will never work...

Should I use the full quote from this article? I can see herbicides being eliminated with this method, but not pesticides, ferts, or fungicides. Anyone who grows would know this.

Did you miss the part where I say 'In general I think it's a wonderful idea?' I'm not questioning the ability of vertical grows to produce a whole lot of vegis. I am doubting their economic viability.

Verticle farms are a fantastic idea. Building up instead of eating up land moving OUT is a much more logical idea.

great article and it has several advantages over the common and wasteful system employed in the u.s. (((advantages))): closed loops mean greater efficiency. potentially cheaper due to the elimination of pesticides - healthier (obviously.) immediacy of location cuts transportation costs, but that doesn't have to be limited, as it could be used to ship produce elsewhere (even though this would be self-defeating - much better to have similar facilities in other cities.) due to it's efficiency and local availability it's better for the environment. advantages for local job market, immediately and secondarily. increased tax base for local governments. no doubt i've overlooked some other advantages. possibly could be on-site, in-building supermarkets which could cut back on packaging, thus another benefit to people and our only available planet.

This idea has been around for about a decade, but it's only just starting to enter into the mainstream conscious. The other positive thing about vertical gardening is it helps to cut down on surface water run off, and provides a cooling effect in urban heat sinks, as well as providing insulation for the buildings themselves. Of course it won't be applicable everywhere, but it might start getting people back in touch with the earth and growing their own food. Something that needs to happen fast so people will learn to respect how food is produced once more. We've become far too disconnected from growing.

faved. but see this intended as a commercial application. still, there's nothing wrong with a pick-your-own concept as well. wouldn't that be marvelous? instead of a few of us going to pick apples in limited times of the year, we could go pick everything anytime of the year. that's about as fresh as one can get.

here's a link to the system that does work and has been working: http://www.growingpower.org/ - as vaguely referenced in the article. it creates usable fertilizer and markets delicious food. no, i don't work for them. believe it or not. could easily be adapted to the platform mentioned in the above article.
listen to the deniers and naysayers at your own peril.

I guess this is targeted at me...

I just checked out this site, and I absolutely agree with what they're doing 100%. But note that they're not doing soil-less hydroponics. Most of their growing beds appear to be soil media fertilized with compost and worm castings.

Even their aquaponics setup (very nice!) uses a coir and compost medium, and their website specifically notes that they do this because the fish effluent is deficient in certain nutrients.

All I'm saying is that organic hydroponics is a challenge at best. Most vertical farm proposals specify pure hydroponic systems such as aeroponics so that the growth rate is limited by LED lighting rather than nutrient uptake.

Maybe the best compromise is to produce a base nutrient of worm tea and/or fish effluent with a fairly consistent lab-analyzed nutrient ratio and doctor it up with whatever it's missing (boric acid, chelated iron, etc.) from inorganic sources.

NASA has developed a really nifty closed-loop aquaponics system. In the earth-gravity version, tilapia are raised in an illuminated tank inoculated with ammonia-oxidizing bacteria and shaded by a layer of duckweed (tiny rootless aquatic plants) floating on the surface under the lights. The duckweed is photosynthetic. The fish eat the duckweed. The bacteria oxidize the ammonia in the fish effluent to nitrates, which fertilize the duckweed. One vessel. Just add light and fish fry, harvest mature fish.

here's a link for you. http://www.verticalfarm.com/ hopefully , if you can only think of exceptions to be used to disprove ideas, you may actually find reasons to agree with this new(er) but not entirely unheard of farming (or produce production) platform.
maybe you see only what you want to see - paying attention to that which you think you can refute or distract with. growing power raises fish and produce. the fish create fertiliser and the worm castings used in an area on their property also create fertilizer. maybe you think you've got someone here who is easily misled, but i've actually been there and buy their fish and produce. it's great. don't continue to tell me about growing power. there's no sale of your exceptions to it to be made to me.
fish and worm castings are combined. so, begone and think up more exceptions, if you like.
also, the above article is not about hydroponics in the least little bit. that's why i provided the link - that also came with the article. try it with an open mind - if possible.
that's nice if you work for nasa or you work for some private hydroponics company, or you just think it's neato, but it's off-topic,and perhaps that's why you bring it up - to distract.
i say again; http://www­.growingpo­wer.org/ is a great site, and a great effort. very progressive. also, the ideas being implimented by them are not isolated, but spreading!!! ooooooo! boo!!!

seems to be advantages to using this method. transportation costs can be cut for example. could also foster more farmer's markets, but not necesarilly. if these are built near natural water supplies rather than on semi-arid land (most of california) that would greatly benefit the natural environment. could easily be plugged into existing city water mains. certainly can manufacture the fertilizer for it on-site, as growing power in milwaukee has shown.(it's one of milwaukee's best kept secrets) eliminating pesticides is always a plus.

Water shouldn't be much of a problem. Indoor hydroponic systems, especially advanced systems of the type that would be install in a capital-intensive vertical farm, are extremely water efficient and suitable for water recycling.

Even in my own system (which I no longer operate) I ran a top-off strategy without draining solution during the crop cycle and stopped adding nutrients one week before harvest to promote final ripening and minimize leftover nutrients.

I recycled the condensate from the dehumidifier to mix top-off solution, and at the end of the crop cycle I pumped the reservoir through the reverse-osmosis system to recycle most of the water for the next crop cycle. VERY little waste.

A well-designed and operated hydroponic system uses water and nutrients 20-50 times more efficiently than conventional outdoor field farming and produces no runoff. Hydroponics is certainly the best way to produce food in arid climates, although obviously proximity to population centers is the most important consideration.

growing power uses water that the fish swim in to irrigate crops -indoors. also, i see no mention of runoff in the above article. in fact the featured person (prof. despommier, his degree is unrelated.) refers to a closed loop system time and again. still, in cities with drainage and water systems maintained by public works departments, water isn't as big a problem as in semi-arid climes like california, which to me makes no sense whatsover - very wasteful. indoors, there's the prospect of much less water loss.so, this is one reason the professor cites it's adaptability to water starved areas. it's more cost-effective to contain farming indoors, than to allow (for example) the water to evaporate.
at the site, linked to the featured person, he illustrates many forms of farming. in fact, hydroponics is mentioned in passing, but definitely not the main thrust of his proposal. and, again, this man is pushing it, with this article and his site, but he's by no means, the only one doing this.
advantages: closed loops mean greater efficiency. potentially cheaper due to the elimination of pesticides - healthier (obviously.) less dependant on transportation costs. better for the environment, therefor. advantages for local job market, immediately and secondarily. increased tax base for local governments. no doubt i've overlooked some other advantages. possibly could be on-site, in-building supermarkets which could cut back on packaging, thus another benefit to people and our only available planet.

Precisely....let's start converting the factories from our outsourced manufacturing jobs into urban farms! Sounds like a way out of the Depression we're in to me. And, the best part is everybody could eat organic!

great idea but good luck getting urbanites to put in enough work to grow a garden... investing in earth fare stock is a better plan

This a great idea. In fact, there are many pop bottle vertical farming that can be done at home right now. Just google search it to see what you can grow at home (thus saving $$ on food costs).

He's right. And if it's Organic, I'm all for it. Less Industrialized/Factory food; more family, individual farms--even on rooftops...

Organic hydroponics is possible, but it's usually less sustainable than synthetic hydroponics.

The best organic hydroponic nutrients are made from fish or shrimp meal. This depletes wild fish stocks much like salmon farming. Others use bat guano, which is mined from prehistoric deposits on Pacific islands using methods that disrupt the bat colonies.

Worm castings are very sustainable and very high in nitrogen, but generally low in phosphorous and sometime potassium. The composition can vary substantially depending on the contents of the worm bin, and hydroponics demands a fairly consistent nutrient balance.

Synthetic hydroponic nutrients are produced using the Haber-Bosch process to react hydrogen (usually from natural gas) with the nitrogen in air to yield ammonia, followed by the Oswalt process to yield nitric acid.

Nitric acid is reacted with phosphate rock or animal bones (calcium phosphate), potassium chloride, and magnesium chloride from saltwater to produce the majority of the nutrient salts.

Since the hydrogen for ammonia production can come from solar water electrolysis or biomass gasification, the process is very sustainable.

Also, hydroponic farming uses 20 times less fertilizer than soil farming because the nutrients are recycled in the water loop rather than leaching out of the soil as runoff. I don't drain the nutrient solution at all during the crop cycle, just top off with water and add nutrients to maintain the right concentration. One week before harvest, I stop adding nutrients and the plants suck up the remaining nutrients with extremely little waste.

What about composted kitchen waste? Could that be used for nutrients if it were boiled to prevent mould or fungus?
