Irrigation is impractical for the vast majority of acres producing wheat, corn, beef, cotton and soybeans. Roughly 11% of cropland- non vegetable- is irrigated. Huge amounts of water is used in agriculture but that is dwarfed by the usage in areas that have sidewalks and pizza delivery.
Climate change means a lot more than a few degrees of air temp change... it means the end of rain cycles we rely on for the 100s of millions of dryland crop acres we rely on. It perversely means millions of other acres are delayed in planting due to late freezes and torrential rains, then yields cut short due to early frosts. Once a killing frost hits it doesn't matter if there is a month more of warm weather.
High tech MAY keep the tap water flowing along the coasts, but it won't stop West Texas and Western Oklahoma turning into Arizona. We need rain, good old fashion 1.0 legacy systems wet...
Well, it was 108 here yesterday, and we are looking at temps over 110 degrees for the next few weeks. Water is pretty important here, of course, all the good water goes to the golf courses..crazy.
I am an avid gardener, but I don't grow a lawn. Plus, we follow the old "if it is yellow, let it mellow, if it's brown, flush it down" rule. Wasting water in a desert is criminal.
