Egypt is the cradle of civilization. The Nile hasn't gone anywhere. As soon as they get their heads out their asses and let farmers own farms rather than military cronies, they'll be able to feed themselves again.
No, see, "cradle of civilization" is exactly about resource constraints. They have water and sunlight and good soil, and those are the resources needed for agriculture. People living in Egypt and running short on grain is a temporary condition that condemns their government not a permanent one that condemns their land.
