So far all I've seen is market forces switching from renewable food production (soil and in-situ biological generated fertility) to nonrenewable (fossil fertilizers trucked in from "somewhere else"), rampant soil loss, unsustainable acquifer pumping and salination, water eutrophication, wealth consolidation in food production, and soil erosion on a scale never seen before.
Ironic that you should bring up subsidies, because globally industrial agriculture is almost entirely a subsidized (yet economically futile) endeavor.
I know it's heresy to question Borlag et. al and the "green" revolution, but far from "handling i," market forces have merely enlarged and externalized the scale of the destruction.
Saying that they're not market failures says more about the narrow definition of "market" than about the workings and evolution of capitalist systems (including both visible systems like farms and factories and invisible systems like laws and power structures).
