I think about this too. Has anyone reputable actually crunched the numbers on global crop capacity with and without industrial nitrogen fixation processes? Like if everyone had compost piles and permaculture tracts in their various domiciles could this produce enough viable crop yield to reliably feed the world? Organic micro-farms are cool and all but I genuinely don’t know the answer to the question on a global scale.

we produce many times the food needed to feed the world. we just feed it to animals. most commodity grains grown are animal feed. there is more slack there than most people realize.

some small amount of animal agriculture is probably still a net positive with processing stuff like bean pods, etc., but yeah you solve a lot of arable land problems by not eating flavourless garbage meat 2-3 times a day

I wonder how many people we could feed if we brought back the buffalo and selectively bred/genetically altered them for docility, obedience, and meat. Like, full on utopian-scienced them, and how much of that technology exists today or would be achievable shortly if we prioritized it.

This is definitely true, and certainly bad, but it doesn’t change the fact that most industrial agriculture is made possible by (currently) unsustainably energy-intensive nitrogen fixation processes. The question isn’t “can the world produce enough food for everyone (right now if organized properly)” it’s “can the world produce enough food for everyone indefinitely in a way that doesn’t require unsustainable chemical processes”.

its difficult to imagine a sustainable fertilizer for the population we currently have. pre-haber-bosch, we were on a fossilized guano-backed boom, and prior to that I believe was crop rotation? which isn't gonna cut it. ironically I think that continuing current processes just with nuclear energy as the input is probably the most potentially sustainable option. or mass legume cultivation (like on the scale we currently feed to livestock) just as tillage

Alternatively, we start treating civilization like we're a space colony and have cities basically function as a closed system, recycling every turd and body back into the system rather than let it pollute our waters with nutrients that gently caress up the local ecosystem.

There's also lots of work being done on developing perennial staple crops. No idea how viable or worthwhile they are but the neatness levels are off the charts https://en.wikipedia.org/wiki/Perennial_rice I have a teeny plot that I was using for a crop of flax before my foster dog destroyed it, thinking of planting some wacky perennial wheat next year. In true american fashion there's a trademarked version of a perennial wheat called "Kernza", a local brewery makes a beer with it but haven't had it yet

the thing about stuff like livestock such as buffalos and whatever other animals is you can just let em run loose and go eat one when you're hungry. Just because they weren't in pens doesn't mean they weren't cultivated. Similarly the cow is kind of a big deal for a lot of places where you can let them graze on lovely rangeland and then milk them, you can be vegetarian and still have zebu.

I like the idea of eating seasonal fruits and veg, and more local staples. exchanges would be cool, too, to increase diet diversity and as like a food cultural exchange. meal services that focus on this could be good, too

This is probably stupid and might not be the right thread for it, but I had a thought the other day: Most trees planted in public spaces are intentionally male, so that the poors don't have any food to just go grab and eat so now they gotta go buy McDonald's fries instead of picking an apple off a nearby tree, right? Is it possible to graft female fruit-bearing trees to the existing male trees, guerilla-style? Would the grafts produce fruit? Could I just buy a female tree and turn it into X number of grafts to sneak into the trees in the public park? I guess what I'm saying is can we give all the trees sex changes to help feed the world?

I am not a botanist, but I think that it is fairly uncommon for, say, a tree to be male and thus not produce fruit. Your example of apple trees, some might not be self-pollinating but having a few should be enough. There are cherry trees that blossom, but don't produce (palatable and large) fruit. Some trees that make fruit become a nuisance because no one collects the (possibly unpalatable) fruit and it falls all over the sidewalk and road and ferments and has large pits and... There are some park benches by me that have fruiting grape vines shading them. You can reach up and get some grapes.
