In the cost/benefit world i.e. the real world the economics of irrigation largely depend on climate and markets. Long growing season supports irrigation. High value crops also. Short growing season and commodity crops grown far from market not so much. The irrigation districts in Alberta are a huge success story in many ways but so are the subsidies that make them possible. Not sure that the same model works in moister, cooler Saskatchewan.

Very well described.

Irrigation makes California's ag production dwarf all others even with highest cost water.
But if you have crops and climate that in some years it's optional to run the pivots I'm not sure how well that will pay.
