Chris Corbin argues that flood irrigation isn’t the bogeyman it’s frequently made out to be.
Some footnotes Chris and I came up in a twitter conversation:
- Ward and Pulido-Velazquez, PNAS, Water conservation in irrigation can increase water use
- Huffaker, WRR, Conservation potential of agricultural water conservation subsidies
- Pfeiffer and Lin, The Effect of Irrigation Technology on Groundwater Use
This is all related to a post I’ve been cooking up, not yet completed, on the water policy version of the Jevons paradox. Its common formulation involves energy, and the assertion that efficiency measures don’t save as much energy as you think. Given groundwater recharge and return flows, the principle also applies to water.
