In this case...a global food crisis caused by population growth, rapid urbanization, extreme weather, and political crises...
Population growth should be the easiest to project using birth rates, mortality rates, consumption...it's just mathematics and gaming it here or there isn't going to result in less demand for resources.
Urbanization...so-called "smart-growth" models no matter how much they expand/promote them is going to erode underlying demand for food...I mean is a centrally-planned community going to eat less food? Well, only if the government has anything to say about it, and that applies to all...but sure it will be easier for them in the initial stages to manage distribution.
Political crisis, well we see this one playing out all over and not to the advantage of entrenched establishment elites...all centralized authority can do is make things worse, not better...it is not in their nature to reform themselves and be answerable to the people, so this element seems a wildcard any way you look at it.
Extreme weather, yes, here we go...dig deep enough into this one and the high-priests of the climate change cult we be everywhere...if anything is going to be exploited for the benefit of the establishment elite it is this. Sure, weather patterns from year to year in food producing regions is going to have an impact on yields, prices and inventory...and yes the PTB's can game prices in commodity markets but not at a sustainable level should serious shortages of foodstuffs be widespread and repetetive.
Anyway...kinda feeds into the SNS story...and to the extent that there is accuracy in the projection...the primary takeaway is: don't count on the government (at any level), depend on yourself!
