We know how to stop that. We don't have to sentence people to subsistence agriculture. When you know better, you do better, and we know better.
We can farm in ways that build high carbon soils. We can do this even in the 3rd world. Teach people the proper techniques.
It's nonsense to claim that we just have to accept this kind of collapse.
I read quite a long article once, it was about efforts to teach Iraqi farmers how to use modern techniques and modern equipment.
The main problem they encountered wasn't conservative mindset. No, the farmers were willing to try something new.
It was missing infrastructure. Once you start using any sophisticated equipment, you need repairs, distribution of spare parts, good documentation in local language etc. Such a system is not easy to set up in a really foreign country, much less so if security is problematic.
