Not really, all three of them are sociological problems. And, at least for the first and last, we could already have mostly solved them but for the intransigent insanity of various political cults.

It's not technological progress we need; it's cultural progress.

Logistics of food distribution is a technological problem, and nowadays famines tend to happen less due to absolute shortage of food in a wider region, rather than due to insufficiently developed traffic infrastructure.

IIRC no place in the world which has hard-paved highways has ever seen a peacetime famine. That's almost exclusively the domain of mud road territories. Of course, this is partly a correlation (mud road territories have worse governance and more banditry), but there is causality as well.
