english: Irrigation starts to make you be allowed to plant stuff where you want it, as opposed to where the rivers flood. You start getting this organic agriculture; you start putting machinery onto this stuff. Machinery, with a whole bunch of water, leads to very large-scale agriculture.
non_english: Irrigatie laat je toe om dingen te planten waar je maar wil, in tegenstelling tot waar de rivieren overstromen. Je begint dan met organische landbouw, je zet machines in. Machines en veel water leiden tot zeer grootschalige landbouw.
