Airdropping "tons of food" wouldn't move the needle. Airdropping thousands of tons of food per day, every day, for years on end would temporarily reduce famine. It wouldn't prevent famine (armed groupings who would gain control over of the airdrops wouldn't necessarily share), and would destroy local farming, and would be horrendously expensive but it's possible (see e.g. Berlin airlift) if someone major really wanted to dedicate all their airforce (again, see e.g. Berlin airlift for what it takes) to that.
