Ask HN: Practical ways to make local communities resilient?

While I find our progress as a species very exciting, I can’t help but think to the possible ways it could halt or slow.

While globalism is great, I (rightly or wrongly) think that individuals and communities should be self-sufficient where possible.

Observing how effective has been at disrupting societies, I fear the outcome of something less forgiving.

I write the under the shadow of impeding climate change, as groups of imperfect humans hold the keys to nuclear warfare. It’s not to speak of threats we are yet to identify, or are too complex to go into here.

Are local communities key to resilience against the potential downfall of civilisation? I understand this may be quite dramatic, but it seems that striving for local self sufficiency also positively impacts the climate.

It’s not clear to me how I can make my small town more self sufficient and independent for the future. Does anyone here have any tips? What should be prioritised (there’s plenty of water)? What’s the 80/20 of self sufficient communities?
