This is the main thing that has gotten me worried. In 2010 there was a heatwave in Russia that affected the wheat harvest and in 2011 we had the Arab spring. There are an increasingly large number of failed states or states that are on the verge of tipping into that in that region of the world too. Lebanon's grain storage capacity was reduced to a month's supply after the Beirut explosion. Water tables are very stressed in Morocco which supplies the majority of the worlds rock phosphate which is the critical input into phosphate fertilizers which massively boost agricultural productivity beyond normal means. When you dig down into it it's clear the world is in a "food bubble" supported by over-pumping of water from aquifers, hydrocarbons, globalization.
The ripple effect the economics are going to have will be pretty far reaching.
For every one person who participates in a helpful community disaster preparation program, there are 20 who will instead look for ways to profit from a disaster and screw everyone else.
Whereas folks in my neighbourhood all pitched in to do grocery runs for the old and infirm.
> … after every hurricane, you'd see dozens of guys driving around with 4 brand new generators in the back of their pickup trucks, looking to sell them to desperate homeowners for 10X their cost.
Those guys are doing good: they are taking generators to people who need them. You see only the price, not the fact that the person who pays that price thinks he is better off with a generator than with the money. And those higher prices incentivise other folks to bring in more generators, which means … everyone who needs a generator will eventually get one. That is how markets work!
Even here in South Australia where we were had tiny numbers (a few 10s of cases a day), the supermarket shelves were stripped bare of toilet paper, sanitizer, hand towels, food).
People suck
I’ve always felt part of prepping should be to establish documents that details alliances and property rights with your neighbors and other preppers so when the government collapses you have a procedure to bring up a local rule of law and order very quickly.
The main thing currently that no one seems concerned about is the reduction of grain production from Russia and Ukraine because of the war. This is going to have a global impact and will increase food scarcity that a 3 month individual supply can not do anything about.
