Genesis 41:53-55

Verse 54

The seven years of dearth began to come - Owing in Egypt to the Nile not rising more than twelve or thirteen cubits; (See Clarke on Gen 41:31 (note)); but there must have been other causes which affected other countries, not immediately dependent on the Nile, though remotely connected with Egypt and Canaan.

The dearth was in all lands - All the countries dependent on the Nile. And it appears that a general drought had taken place, at least through all Egypt and Canaan; for it is said, Gen 41:57, that the famine was sore in all lands - Egypt and Canaan, and their respective dependencies.
Verse 55

When all the land of Egypt was famished - As Pharaoh, by the advice of Joseph, had exacted a fifth part of all the grain during the seven years of plenty, it is very likely that no more was left than what was merely necessary to supply the ordinary demand both in the way of home consumption, and for the purpose of barter or sale to neighboring countries.
