> owning land you can live off of is a protection against all form of “dooms-day” scenarios

I imagine that global warming, if it hits some threshold/tipping point that changes the climate enough to wreck the land, might be the one counter-example here. Though I don't know enough about farming to know if it could sustain through a wide range of climates and potential consequences of severe temperature/climate change.

Rough rule of thumb: if you're in a temperate climate now, you're probably ok. Crops that will grow well will change, but as long as the water doesn't dry up, you'll be able to grow something.

If you're in a hot climate now, move.
