The global shortage of diesel fuel effects everything but it especially hits farmers hard as all farm equipment as well as every truck used to transport farm equipment is fueled by diesel. We all need food so policies which drive up the cost of food are inherently bad especially when they are being done deliberately in a time of global shortage.
When faced with starvation we will see massive refugee flows but that, again, is probably what Klaus Schwaub wants. He seems to want to destabilize old nation states so they can be replaced by a new elite run global techno state (run by people like him and his friends, of course). I just don't see that as a good thing.
