(Dan here…I lifted reader Michael Smith piece on water use in open thread Dec. 22. The topic is well worth writing about…AB used to discuss this issue regularly starting in 2008 during the severe drought in the US when the southeast was contemplating court action amongst themselves to ensure their own supplies.. Search “water” in AB for a sample)

I should probably write a longer piece on this but I’ll try to summarize the best I can.
Had lunch with a prominent client scientist in my region that frankly scared the crap out of me. The hydrologic cycle is being seriously disrupted.
Here is what we know:
The Powell 100th meridian has moved east, by a lot.
Approximately 85% of our produce comes from drought areas (Mexico, California, etc)
Approx. 50% of water usage is due to agriculture and most of that happens in western states. My farm is in cow town, Texas and we have very poor surface water and rain patterns, so we pump from the aquifer.
Major municipalities are being forced to stop pumping from aquifers. City of Houston vs. Dow Chemical Co. is and interesting case where the fight over land to impound water is being fought over.
