They didn’t irrigate open fields anymore, because with their aquifer declining that was illegal as well as useless. But they had genetic crops with the chlorophyll hack, and they’d done a great deal with greenhouses. Enormous greenhouses, beautiful ones, huge curved foam-metal spars and vast ribbed expanses of dew-beaded transparent membrane, greenhouses as big as cornfields, greenhouses that were their cornfields, basically. Vast expanses of well-designed, modern, moisture-tight greenhouses, pegged down tight and neat across the landscape just like a big sheet of giant bubblepak.
