Traditional agriculture has "solved all of the scale problems" through the use of pesticides, destructive monocultures, and disruption of the natural water cycle. It's also built on the idea that diesel is cheap both for the tractors to farm in the midwest and the trucks to deliver goods to markets around the country. Should any of those fragile pillars collapse due to regulation (not likely), major environmental catastrophe (pretty likely), or disruptions in the global fossil fuel economy (possible), solutions like vertical farming start making a lot more sense.

Around 6 years ago I quit my job as a developer to dive into agriculture. I learned about syntropic agriculture systems and felt in love with it because:

- You are able to work with space and time in a way to maximize yield (not 1 crop yield, but but multi crop) - It focus on being biodiverse - It builds forests

So in this systems you will see rows of trees intercalated with rows of beans, corn, soy anything "weedy" or grasses... Harvest this small plants for many years, after a few years you harvest fruits, and after 2 decades you harvest the wood and start over. All with extensive pruning.

This way you end up with better soil each time without machines or fertilizers (sure you can speed even more the process with them), its a type of agriculture focused on nature's processes instead of inputs.

There's an interesting video about it showing some big farmers here trying to build machines better adapted to this kind of agriculture, this is the biggest bottleneck to scale because right now most machines are very focused on monocultures: https://www.youtube.com/watch?v=gSPNRu4ZPvE

A really great non-profit focused on more sustainable agriculture is The Land Institute. Generally people also don’t also understand that some advancements in agriculture take decades or even centuries. One example of an advancement from The Land Institute is their focus on domesticating a perennial cousin of Modern wheat. This is no small task given humans have been domesticating modern wheat for thousands or years.…

They actually had a run with the grain in General Mills cereal! The commercial name of the Modern wheat cousin Is “Kernza”

Can you explain this "disastrous logistics chain"? I am a bit confused given all the effort that goes into logistics by farm companies.

It's the logistics chain from the farm to your plate that's the disaster. That's not for lack of trying. But having exposure to farming growing up, there's no good way to get a ripe berry from Washington State to Florida before it spoils without freezing it, genetically engineering it (which is fine, I'm pro GMO, it's just costly) or treating it. Even if you do, handling it will see large losses. So the trick is, how…

Well, you can get it there, but berries aren't worth enough to make that journey by air. That is generally reserved for seafood and there is an equally amazing logistics system to do that. Calling one of the most amazing processes on the planet "disastrous logistics chain" is just disingenuous.

You seem like the right person to ask about this. My sense was that hydroponics were so expensive that they really only made sense for one crop: marijuana. If your plant is selling for $1000, then spending $50 per plant to increase its yield and 'baby' it so that it sells for $1200 makes sense. But for most plants, it doesn't make economic sense. (Tomatoes, maybe. But they're going to have to sell for a higher price…

There are lots of really expensive products that can be cultured indoors, are perfectly legal, and aren't drugs

I'm not being dense here - I really thought there weren't? Like the core problem with ag as a business is that it's very low margin and it's extremely hard to make money.

I can only think of a handful: marijuana, fancy tomatoes at Whole Foods, maybe coffee or vanilla (?) beans... but even there, notice how there's either fierce competitive pressure, or it's possible to easily overwhelm the market (vanilla beans have to compete against synthetics). I mean there are surely some I'm forgetting, but it's a small number, and I thought that deterred VC investment.

For your staples - corn, soy - that's still much cheaper to grow outdoors, so hydroponics can't win that market.

I would like to build on top of your point: - Indoor farming would not have to worry about things like drought. As a water feeding system can be led all the way to the ocean and the salt removed using pure sunlight as power. - Indoor farming has shown to yield crops with 96% less water in many cases, again solving the problem mentioned previously. - Many areas don't have ready access to tons of water so these water c…

>Indoor farming would not have to worry about things like drought. As a water feeding system can be led all the way to the ocean and the salt removed using pure sunlight as power. Are you aware of how much water it takes to produce the output of the Midwest or Central Valley? We'd be talking about the largest desalination project in human history by orders of magnitude. As of 2013, Israel had a desalination capacity…

> As of 2015, the US used ~450 billion cubic meters PER DAY for irrigation

I think you mean to say 450 billion liters, which would be 450 million cubic meters.

Your source says this: "For 2015, total irrigation withdrawals were 118,000 Mgal/d"

So roughly speaking Israel desalinates in a year how much the US uses for irrigation in one day. That doesn't sound so outrageous. Israel is a small country.

I believe I've never actually eaten soy, and I rarely eat corn. I'm also pretty sure the amount of wheat humans eat is less than what we feed to poultry and livestock. The author seems to conflate the purpose of the "modern row-crop farmer" (which is mainly to repay their huge debts and to feed cows and chickens), and the solution touted by vertical-urban-aqua-dome-whatever-ponics: to provide year-round, local, fresh…

It’s very unlikely you’ve never eaten soy, unfortunately. It’s essentially added to every processed meat product, nowadays.

Hello, also a developer who's interested in agroecology. I actually also left development (as a job, not as something I do) in order to pursue a more human-centric approach to agriculture. With automation, it seems obvious we'll be seeing way more unemployment than what's happening right now, which is already alarming; small farms with synergistic crops & forestation seems like a no-brainer to achieve food sustainability. Plus, chemical pesticides are usually not used in syntropic systems, which makes it good for your health too.

I dropped out of Agroecology course in 2018 but I actively work with it or did before the pandemic at least.

Also, indoor and especially vertical farming can save precious land. Maybe the US has enough land for farming, other countries certainly do not. Rain forests burned to make space for soy or palm oil are proof of that.

Rain forests are being burned down because these areas are poor and farming is the simplest way to make money starting from scratch. Multi-million dollar vertical farms don't help.

Agreed. I grew up in rural Australia, when I moved to the city it was funny to see people talk about farmers in a willy nilly fashion. Farms are extremely hard to build, and the knowledge to run them has to be built into tradition. I'd wager if a governments policies bankrupted a large amount of them, you could almost starve the nation with no remedy. It would take lifetimes before anyone learnt how to till the land…

I agree that farmers are misunderstood and under-valued by people who are only able to live in stability because of the ability of farms to deliver food to them, but isn't farm complexity able to be documented and analyzed in a similar fashion as other "very complex" fields like law and finance? It seems like farmers are still beholden to long "if-then" chains and risk analysis (what to plant, where to plant, how to…

I think you're right to believe that because it is true and I skirted over why I believe it takes generations.

It is not impossible but difficult to document how to do effective farming because every farm has its own individual needs. And what may be true for one farm will likely not be true for another. Hence relying on first hand knowledge, albeit extremely fallible, is more reliable than reading a book and then destroying your crop for a year. (Obviously farmers read, study and improve)

The main reason would be location.

- How does water irrigate around your property? Where is the clay? Where does the water lock in when it sinks in different acres? What happens when there is a drought in this area? What happens when it floods? What should you do when there is extreme weather? - What makes the soil in this locale good? What is it naturally good at growing? How should you replenish the soil? What native wildlife contributes to the soil? What insects plague the area and do they have decade long life cycle bursts? What to do when a swarm of locust come? - When does your first frost generally occur? What plants can you grow through a frost? Maybe Kale will survive because although there is frost, you live in a valley where the humidity is higher so the Kale can live. You can't grow X crop because the wind is ever so slightly stronger every 5 years because of atmospheric shifts.

And just to make it more fun, sprinkle on the problem of economics(supply/demand) and logistics.

Also it would be hard not to meet a farmer who calls it a "way of life" because it absolutely is. They live far away from the spoils of civilisation, work incredible hours and live isolated lifestyles. They laugh at city folk because a city man "wouldn't last a week on the farm", which is probably true. Fun fact: Australian farmers have twice the national suicide rate than the average man.
