I've heard that permacultural practices can compete in terms of output, it's just harder to industrialize. I wonder if improvements in robotics could make this sort of approach more feasible, or if it really is comparatively productive in any case

> permacultural practices can compete in terms of output, it's just harder to industrialize Then they can't compete – yet .

I think they meant competitive in land yields, not prices.

Maybe we could do three good things at once: - switch to this better method of farming - end the corporate oligarchy controlling food by having smaller farms - shift people out of net negative “services” into farming I don’t see the downfall of industrial farming as a bad thing — they’re a whole problem all on their own (including the recent push to take away family farms from the Dutch).

Because the Great Leap Forward was such a smashing success, we need to do it again?

> There are also quite convincing studies that show even worse declines for insect populations Has the evidence improved recently? About 3 years ago there were a few papers, including a meta analysis (-ish), which were suggestive but also noted the lack of longitudinal studies, and their lack of geographical diversity (Germany and UK as I recall). The consensus was that everyone was certain there was a serious issue,…

While not particularly useful as a scientific method, and obviously not attempting to counter your broader point asking for more detailed analysis, there’s incredibly compelling evidence: Go for a 100 mile drive at night, and count the bugs on your windshield. Ask your parents about it. Ask every 70 year old you know. Bugs are in decline. There’s absolutely no lack of evidence. We know it’s real. We just haven’t cata…

Could this effect be caused, or enhanced, by the aerodynamics of the modern cars?

Whenever possible, buy Demeter products. Their approach to farming improves biodiversity and soil quality.

> 35% more birds and 23% more insects are found in organic farmland thanks to the creation of natural habitats and the absence of chemical and synthetic pesticides.

We, customers, vote with our shopping behavior.

Yes, those products are 100-200% more expensive in terms of money. But don't forget that there is a huge price to pesticide use that is not passed through to the customer.

Slightly off-topic, but because of farming we also started to have problem with mistletoe. Many small bushes of rose-hips, blackthorns and other food that birds usually eat disappeared because of smaller fields being merged to one, flattened. So what birds eat now is mistletoe, spreading it from tree to tree by wiping their beaks onto the bark of the tree, leaving mistletoe seeds there.

To clear mistletoe from that many trees is fairly expensive so owners usually don't do it, and we have alleys and alleys of trees full of mistletoe. Eventually the tree dies because of mistletoe parasitizing it.

And eating less meat, so we can do with less agricultural production.

Pasture farming on marginal land is part of the solution. Industrial meat farming is part of the problem. They're two different things.

They are, but pasture farming implies eating less meat. We are currently near a billion cows worldwide, we don't have marginal land for all of them.

That means meat is going to be expensive and you'd rather eat avocado toast instead. Unless demand suddenly drops or we scale growing meat from a lab.

There are also quite convincing studies that show even worse declines for insect populations, again mostly due to industrialized farming techniques and the widespread use of chemical fertilizers and pesticides. The standard approach in the EU to work against this really worrying trend is to a) bring more and more land under some form of protection and remove it from agricultural production and b) increase the share o…

Joel Salatin and Richard Perkins (among many many others) have done great work by applying permaculture principles to farm scale. The ”movement” is called regenerative agriculture but you can also find lots of bullshit under that term (ie. Monsanto has used that term in their marketing)

I think that's by far the biggest lever given how inefficient meat is at converting land area & water to calories.

Pasture farming on marginal land is part of the solution. Industrial meat farming is part of the problem. They're two different things.

"Pasture farming on marginal land is part of the solution" Can you elaborate? I don't see how this is superior to leaving it fallow? I have a few acres fallow and am right next to a quaint organic farm and I do see quite a few more bees in my tall grass and wildflowers than I do in their grazed land...

Lands are not equal. They all have different conditions. Some land for example can't grow food but is good for grazing.

Grazing, done correctly, is beneficial to the land too. E.g. grazing brings dungs to the land. The dungs give nutrients to both plants and insects. Stamping the land aerate the soil and exposes insect for birds, hence limiting pest. Birds spread seeds. Everything is in balance. Food is ultimately created from sunlight.

Industrial farming, on the other hand, simplifying heavily, is converting fossil fuels into food.

Yes e.g [0]. Neonicitinoids in particular are basically nerve agents for insects that we wantonly spread all over their habitat, and which turn out to not remain localised on crops, but spread through runoff, via pollinators, etc. As you might imagine if someone were to spread sub-LD50 concentrations of novichok all over the human environment, the widespread use of these componds dramatically affects insect behaviour and therefore survival rates.

> holistic grazing

Unfortunately this in particular turns out to be unsupported by various studies that have been done to try to validate the claims (e.g. [1] for a popular article with some useful links).

In general the debate between nature-integrated farming vs maximising yield in smaller areas is complex, and I don't think I know enough to summarise it in a HN comment. For example [2] claims that maximising yield, but in smaller areas, is a better overall strategy. But I suspect the outcomes depend on exactly which factors you include in the model (e.g. if you want high yield farms using artificial fertislisers to maintain that productivity, do you account for runoff into rivers that can then have a non-local environmental effect? Maybe studies do this but, not being an expert, it seems hard to model).

In any case, a great deal of the land used for farming is given over to pasture, or the production of livestock feed. [3] has a map for the UK, showing that about half of the total land area is used for beef and lamb production alone, plus a similar area of land overseas. This compares to about 8% of the UK that forms the urban environment. So clearly there's plenty of scope for improvement here, but it depends on the will to change; an understanding that the world has value even when it's not farmed, and that we should stop subsidising, and therefore encouraging, high land use, high carbon, diets.
