The dramatic increases in per acre yields over the past fifty years are closely tied to equally dramatic increases in per acre energy inputs over the same period. The Green Revolution amounts to the replacement of sunlight with hydrocarbons as the main fuel of food production.
Global oil production has now peaked and will slide, sooner or later, into permanent and progressive decline year-over-year. When that happens, all the blue-sky technology in the world won't keep food production rates increasing.

When that happens, all the blue-sky technology in the world won't keep food production rates increasing. Hydrocarbons aren't the only source of energy into the future. Your complaint is like noting that a shortage of horses in the 1880s would lead to a lack of future mobility. When resources fail, you change the rules of the game beyond what can be imagined at the time. Technology has always and will always tackle our scaling problems. At least, if a few thousand years of such is good precedent.
- RyanMcGreal 17y ago> Hydrocarbons aren't the only source of energy into the future. Okay, so name a production-ready source of energy or combination of sources that broadly matches oil's density, portability, fungibility and diversity of uses. We don't have decades to come up with something else: oil is already at its maximum production rate. As soon as this recession ends and demand for oil starts growing, we'll see triple-digit price spikes again and more economic volatility. Your blithe mantra about "technology" ignores the crucial fact that the technology that powers our society runs on massive and ever-growing inputs of energy. Our one-time allotment of cheap, abundant energy is already more than half-consumed, and the awkward fact is that we're absolutely not ready to transition our economy over to something else.

I bet people were as cagey as this back when coal ruled supreme and oil was barely used. Solar, nuclear, geo-thermal, tidal, wind - sure, they all have cons compared to oil but they have pros too and technology will advance to a point where these cons are heavily reduced. We don't have decades to come up with something else: oil is already at its maximum production rate. That's not true. Just considering OPEC, they keep oil production below maximum to control prices. Further, this past year has been a bumper year for the oil industry with significant new field findings. Our one-time allotment of cheap, abundant energy is already more than half-consumed Oil's not a "one time" deal, so I assume you're talking about the Sun. The Sun is half way through its life cycle, granted, but that's a far bigger issue that we can deal with thousands of years down the line.
