Advocates of regenerative agriculture claim that it could absorb all
of humanity's CO2 emissions.
I don't have the basis to judge claims about regenerative agriculture.
I can't tell whether they are valid, because I don't know any ground
truth from which I can deduce anything in that area. And I don't know
of any unbiased entities I could have confidence in. Are any farms
succeeding in business using these techniques?
Is it possible to set up a regenerative agriculture emissions
compensation scheme? How would it measure up, in terms of costs per
ton of CO2 absorbed, against investments in increased energy
efficiency? Can the benefit of improved or protected topsoil be
quantified?
It would be good to spell out the claim that is being made. What are
the claimed benefits, and what are the costs? For instance, the claim
could be, "This is a better method of agriculture and farms should
make the investment to switch now." Or it could be, "This system or
agriculture can't compete today because it would require more farm
labor, but we must adopt it for civilization to survive." The difference
is fundamental.
