I'm gonna be honest I do not understand the economics and logic of vertical farming. You're basically putting plants in expensive, complicated buildings operated by extremely expensive and complicated robots, then you turn energy from the sun into electricity and back into light so you can grow the plants when you can just... farm in sunny places instead? Plants have the ability to turn sunlight into tasty nutrients…

Salads are economic to produce because they have no calories. Calories = Light (energy) + Fertiliser. Efficiency of an LED is like 40%, and Photosynthesis efficiency is like 2%. In other words calories are expensive and ineffieicent to produce through artificial lighting, no amount of 'startuping' will change that. Also nothing here is new, we've had greenhouses, artificial lighting, hydroponics, aquaponics, aeroponi…
There are some things that were not available 50 years ago. Better robots, better accumulators, flying drones, image recognition, AI able to make complex decisions. Those things might reduce need in humans and humans are not cheap.

This is a big one, and we should aim for rewilding in the reclaimed space. Agriculture is one of the biggest drivers of habitat loss and thus biodiversity loss.
I wish we could properly account for this negative externality. To me the ideal state for every inch of land is it being a wildlife refuge. To that end I'd love to see a tax that gets charged for using land for anything else. I think it would drive a lot of improvements like vertical farming

- 250x less water - Sun/heat/light maybe needs to be converted but it's always used in the right amount for each crop - Controlled environments protected from plagues, floods, fires... Crops are not lost due to uncontrollable events and a lot of savings in chemicals to protect them from bugs - Saving the cost of SCM (transport and intermediaries) which is sometimes much bigger than producing. In farming is actually a…
I too think that a vegetable and fruit need sun, win and soil to taste the best. Cannot prove it though.
It's also possible that the type of tomato they choose to plant will taste like cardboard even if grown in a regular farm.

Most crops are grown with this thing called "rain" and without any supplemental water. Using just rain means they are part of the natural transpiration and precipitation cycle, so their unnatural water usage is 0. A few days ago there was a post here about water now being traded as a commodity. In many parts of the world, the water supply is far from guaranteed and must be shared with the local environment, populatio…
Plants don't destroy water, they store, move and clean it.
Rain is great, and Earth's water cycle is closed, but plants evaporate water but you won't get it back as rain immediately.
Plus if you install irrigation you are taking water away from somewhere that would likely not evaporate that fast. (Eg from a river.) And if you also happen to have drainage, (eg if you converted a wetland area), then you suddenly discharge too much water from that region, and you won't get it back as rain.

> It's first in relatively recent time (last 30 years or so) that this has receded in importance. That's what I mean by decades :-) I'm 40 now, so this means at least since I was 10.
Yeah, I didn't mean to sound like I was contradicting you. Just more background. This used to be a big deal, until people started forgetting about it, and now people are suddenly remembering it again.
As much as I tend to prefer text I'll still admit there are times when it is harder to understand the intent.

Somehow the water used by [almond and whatnot] farmers is a problem in CA. Rain is great, and Earth's water cycle is closed, but plants evaporate water but you won't get it back as rain immediately.

They are problems though, we haven't used all of the globes arable land but that doesn't mean we are able to or even should. Consider that much of the remaining arable land is forests we really need to keep. Not all of that is suitable to the types of crops we want to grow, and not all of it is available to the countries currently requiring more food. Arable land is a resource not available to everyone as well, and w…
> Absolutely there is room for development of more traditional farming I'm not talking about traditional farming. I'm talking about using "low tech" solutions but monitoring them scientifically. For example, flooding in the UK is becoming a bigger problem, partly because of more rain, partly because people are allowed to live on flood plains. However a significant change is the way farming has modified land drainage.…
> There are no real incentives to change this.
Well, yeah, it's not surprising. UK is not really looking far ahead nowadays.

KaiserPro had good rebuttals to some of your points[1] so I won't repeat those, but here are some more: > - 250x less water Most crops are grown with this thing called "rain" and without any supplemental water. Using just rain means they are part of the natural transpiration and precipitation cycle, so their unnatural water usage is 0. > transport Bulk transport is incredibly efficient. IIRC, many food products spend…

This opens the possibility of "farm" to plate under a few hours for what is out of season.
