Re,

everyone can be wrong, it seems from sources arguably arguable (Europe - ecology greens) that about 60% of the water goes back into the atmosphere (and not 70 as I said).

On other sites (2006 Irrigation Symposium), the water gun is considered a very low efficiency device compared to other boom systems.

But I know the agricultural world well and its enormous difficulties, it is not them that I target but a European agricultural policy that I do not understand.

In the end, 100% of the water is found in the atmosphere, if in passing it allows to produce food, it is better.
It is sure to water in full sun, it's not great, but if the irrigators only watered at night, they should double their equipment, which also serves only 3 months per year.
Sorry to have been a little aggressive, but I do not understand too much this demonization of irrigation while on the other hand the FAO is worried about the low use of this technique in the world.
I am rather agroforestry, with blind ditches along the rows of trees to recover the runoff and infiltrate them to the water table.

Hello,

no problem when you are passionate the lyrics are often a bit virile! That said, I agree, we must not demonize irrigation, it is as I mentioned that has made the Arab world one of the rich areas in agriculture until the end of middle ages. What I regret is the depletion of resources to make food for cattle in large part. Are there no other plants that consume less water? Do we need so much meat when we know that it is unhealthy in high doses? (I am not a vegetarian so I do not preach for my chapel). This morning I learned that I do not know which organization advocates the return to animal fauna for pigs and cattle to overcome the price of soy (I think) Brazilian). Lessons do not serve? Can not alfalfa used for centuries take precedence over these fertilizer and water-consuming fodders?

but we move away from the subject.

cordially
