The question does not say which transfer so I guess
it is the transfer of crop from South Asia to Middle East. This brought major
changes due to some common factor involved. Different crops need different
climate to grow better and this transfer provided that, especially to rice and
cotton. Irrigation techniques were improved for example a technique used by Persians
in about 1000 BC was called "Qanat", which brought water through
tunnels to surface from the basins which caused a reduced amount of labor and a
better irrigation system.
