this was done with irrigation canals and ditches.
vegetable gardens, people often carried their water by hand from a
stream or a well.
Often people farm in a place where
enough rain falls during the year (and at the right times) to water
the plants just with rainfall.
Farmers don't have to worry about the
plants getting enough rain. That's called "dry farming" because the
farmers don't have to carry water to the plants.
There is no doubt that irrigation makes a major contribution to
agricultural production, making a whole range of crops viable in an
otherwise unreliable climate and helping insure against drought.
