I agree, zero substance in this text, as expected from a newspaper article. The problem of newspapers is that they have to churn out articles regardless of what's happening or if anything is happening, which is in stark contrast to post-mortems and compilations of knowledge that were produced based on information being there that is then followed by a need to be expressed, rather than the other way around.

Except that the article places the blame on America's policy of denying the science behind man-made climate change. It might be scaremongering but the article presents uncomfortable observations:

1) China is buying land and food from abroad 2) Some conflicts in the middle east are tied to food shortages 3) Climate change is a threat to food security

So yes, the circumstances are brewing the perfect wet dream for the military-industrial-complex

Yeah, us, and everyone else besides some of the Europeans. China, for instance, is still shovelin' on the coal. Neither coastal property-owners nor any other decision-makers actually believe the disaster scenarios. Even if they did, TFA invoking global warming is more of a button-push than an argument. Few details are specified in the chain of logic from "China imports food" to "world war", but credulous readers will conclude that global warming will make it all worse.

China importing food is neither surprising nor destabilizing. Only in the Washington echo chamber could investment and trade with developing nations be portrayed as some sort of "threat" without derisive laughter ensuing.
