[Compared to Mesopotamia,) Egypt.....created a more sustainable agricultural
system, which lasted for thousands of years...Whereas Sumerian irrigation involved
a complex and artificial network of canals and [channels) that led to the soil
[becoming too salty), its Egyptian counterpart was much less intrusive... [their
irrigation) system avoided the problem of salty soils, allowing Egyptian agriculture
to emphasize wheat production, but it depended on the general regularity and
relative gentleness of....annual flooding.
-Strayer, Robert W., "Ways of the World: A Brief Global History" (2016)
What could be inferred about Egyptian agriculture?



The lack of mountains in Mesopotamia made them susceptible to
invasion.
The Nile's predictable flooding was more predictable than the Tigris
and Euphrates.
The Nile's silt made it a poor location for a permanent settlement.
The Indus River valley's flooding left fertile silt which was helpful
for the Romans.
