I think that it's more of a supply-chain thing than modern farming being inherently more resilient. We can irrigate when it's dry (as long as there's a pipe from water _somewhere_, which isn't always a given). But can't do much about floods. Certain pests can be controlled, but monocultures make for very brittle systems when a pest evolves past the known defenses (see: bananas).

Ultimately, we have transport and distribution across the entire globe, so a crop failure in one place doesn't mean a famine there as we can ship food there (unless you're a poor country, in which case the rest of the world doesn't care much).
