On commence par deux paysages au passage de la frontière entre Arnéguy et Orreaga-Roncesvalles (oui : Ronceveaux et son col sont en Espagne), n'en déplaise aux nostalgiques de l'expression anachronique "de France et de Navarre" (un check géographique et historique s'impose).

On finira cette montée dans la hêtraie et son brouillard.

Southern Alberta has the largest irrigated area in Canada.

A billion-dollar irrigation expansion is planned.

But it's been dry lately. Water allocations have been cut.

Facing a drier and hotter future, a big question looms: 'Where's the water going to come from?'

"A paper published in 2017 estimated that to match crop production to expected demand, water use for irrigation would have to increase by 146% by the middle of this century. One minor problem. Water is already maxed out."

George Monbiot today on the water crisis, the irrigation efficiency paradox and the water demands of a meat diet.

What Is The Ogallala Aquifer And Why Is It Running Out Of Water?

https://www.kansascity.com/news/politics-government/article281504238.html <-- shared media article

"Millions of years ago, sediment from the Rocky Mountains was deposited in the High Plains. Over thousands of years, water dripped below the surface creating an underground water deposit called the Ogallala Aquifer. The water — which spans from South Dakota to Texas and was once the size of Lake Huron — at one point accounted for 30% of the crop and animal production in the U.S…
Although the water source stretches across several states it moves very very slowly. As a result, no interstate compact exists to manage the water in the Ogallala. Instead, neighbors have to band together if they want to restrict pumping…”

Built a water level sensor for my irrigation systems water container. Shows current level in mm via the OLED and via WiFi for low level and leakage alerts.

Uses a pressure based industrial liquid level sensor which is really accurate and stable, fantastic sensor!

based firmware on a dev board. for UI.
MCP3421 for sensor readout/4-20mA conversion.

Building a remote water level readout for my irrigation tank using one of those chonky sewage/~industrial tank sensors and the accuracy is impressive. Paired with a good ADC I get rock solid mm level accuracy. That would give me about 150ml volume resolution.

Negligible Impact On Precipitation From A Permanent Inland Lake In Central Australia

https://doi.org/10.1029/2023GL103913 <-- shared paper

“KEY POINTS:
• A climate model is used to test the hypothesis that creating a large lake in central Australia would increase rainfall
• Locally, surface cooling effects of the lake suppress the formation of precipitation
• Regionally, moisture from the lake is exported to other areas but the amount is small compared to natural variability in Australian rainfall..."”

How humanity might have escaped the

IMO,
humanity should have been implementing and raised-field agriculture, style, including huge and systems in all regions bound to have or experiencing "monsoon type" rainfall for decades.
The necessary construction would dwarf anything in human history.
We are about 3-4 decades late.
