If we were running low on resources for food production you'd expect to see food prices increasing. But broadly, food is cheaper than ever.

Ecological damage and collapses occur well before we'd run out of resources. Just because we can encroach on more and more land, at the expense of the environment, doesn't mean there isn't a problem.

  Increasing agricultural productivity nowadays doesn't involve encroaching more land. And the developing nations, where the populations are booming, are still on the lower end of agricultural productivity. Combine that with the fact that populations appear to top off at a certain level of prosperity, and you'll realize that we'll be just fine.

    > Increasing agricultural productivity nowadays doesn't involve encroaching more land. What are you talking about? 41% of US land is used for livestock production. It's not that efficient, and the perpetual increase in population will just push that higher. > Combine that with the fact that populations appear to top off at a certain level of prosperity, and you'll realize that we'll be just fine. We don't all share in that prosperity. Population is still set to grow in the (perpetually) developing world plagued by poverty. The population growth rate in the 1st world is a targeted rate, a matter of policy, which is met by increasing immigration. Fertility rates on the global scale won't drop so long as child mortality and quality of life isn't improve across the board, and consequently the growth rate in the 1st world is also here to stay.

Food has two types of cost, market value and ecosystem cost. It always has been this case. It's the very reason that crop rotation was discovered. By improving the ecosystem that you farm in (in this case soil but Tree windbreaks also count etc...) you increase the productivity. The issue is that most ways to improve productivity are terribly short term. Think slash/burn. So yes food is cheaper than ever to buy but we are burning through environmental capital at dangerous and irresponsible rate IMO. The cost of food will stay cheap until it's too late and the land stops producing at the current level.

  What, exactly, will "run out" that affects most food production? The remaining soil lifespan in societies with developed agriculture is hundreds of years, and relatively cheap practices can extend that to thousands of years.

      Managing groundwater is an economic co-ordination problem, not a limit to food production. We currently produce crops that are very, very inefficient in terms of water per calorie, because people like them and some jurisdictions like California don't have effective water markets.

        I predict nothing will change until nature forces it, at which point the damage will be irreversible. A small fraction of people live the high life, but a large fraction has tasted it, and almost everyone has seen it. Effectively no one is going to cut down on their consumption because they’re calculating (correctly, in my opinion) that even if they do, someone else will step in and consume their portion anyway.

The thing everyone always forgets about food production in armchair analysis is that it is not constant. Some years we produce more, some years we produce less. We can smooth across space and time to keep short-term or regional shortfalls from becoming a famine, and we do so most of the time, most places. In any year, in any place where there is not a famine, we are, by definition, producing more food than anyone wants to consume, in aggregate at least if not for individuals. Whenever you are producing an excess of something, the price will fall. Famine, if it happens, won't happen as a slow decline of food production, until at a predictable time we cross from producing 100.0000001% of the food the world needs to producing 99.9999999%. It will happen as a slow decline reducing our safety margin until some sort of three-sigma weather event makes for a really bad year -- flooding in some regions kill production here, drought in other regions kills production there, a blight on crops in otherwise fair weather, and the production for the next N months falls below the level of the stockpiles to last. That is the point at which the market will react and food prices will go crazy. It won't do anything to help production -- some things take time, not money. It will just be the world playing musical chairs to see who gets left without enough food to eat.

  Developed countries produce, not a little bit, but multiples of calories than is consumed because people choose to pay extra for tastier but less efficient calories through livestock, and tolerate food waste for convenient packaging and higher quality selection. I don't see any sign of a downwards trend in this ratio.
  - saalweachter 6y ago
    Oh yes; you can slaughter millions of extra cows and pigs in the US to realize a huge number of available calories, while redirecting the grain back to humans, all with no more ethical worries than you've already accepted in producing & consuming meat. A number of other inefficiencies can also go away under emergency conditions -- people will get less picky about their fruits and vegetables in a hurry, and it won't spend as long on supermarket shelves anyway. From purely a US standpoint, yeah, I suspect our agricultural buffers are good enough for anything but a "volcano blotting out the sun" level deviation from the norm. Call it, four sigmas of food security. You'd need an event that only happens once every ten thousand years or so to really bring the US to its knees, agriculturally. My point is -- I don't think food prices will shift much as long as the buffer is positive. If our margin narrows -- less livestock, more of it grass fed on marginal lands, grain spending less time in silos before being processed into food -- to two or three sigmas of food security, I don't think that you'll see food prices rise significantly, from market pressure. I think if things go badly (and there's no guarantee of it at this point), it happens slowly at first, and then quickly, and you can't just point at food prices being low to say it's not about to turn from slow to quick.
