#42Sounds like they need a little Permaculture… https://www.permaculturenews.org/2009/12/11/greening-the-des... The video above is a followup (6 years later) to greening a section of the desert in 2003.
Permaculture don't work with modern tools, it works well in your garden, but require so much labor that you are economically doomed at scale.

That true for now, but building better tools solves a great many problems.
Yeah, we need sort of drones smart enough so they can pick up the food themself.
With this technology most of the permaculture ideas (protecting plants with other plants) can be replaced with drones.

#44Does anyone know the specific tree species planted? I'm working on a project with boswellia species so this is where my curiosity is coming from.

#45checkout the actual forest in Google Maps[1]. If you check the historical imagery in Google Earth Pro, you'll see that sometimes between the end of 2017 and the start of 2018 most of the trees kinda disappeared. I dunno if the forest was cut down or if they just stopped watering it, but its pretty much gone now [1] https://goo.gl/maps/7mtZYS1v5588fdeYA
If anyone else wonders what those green circles are (when you zoom out just a bit more: https://www.reddit.com/r/whatisthisthing/comments/453pj2/wha... (https://en.wikipedia.org/wiki/Center_pivot_irrigation)
Re: Egypt has managed to plant trees in the desert using wastewater
#46It's not clear to me what the source of water is relative to the size of the forest, because IIUC, in dry regions like Egypt (and California, Israel, etc), unless you use drip-irrigation with targeted crops (which won't grow a forest), agriculture requires a huge amount of water compared to domestic water consumption, so the wastewater stream from the latter intuitively can't be nearly enough to support a forest. Per…
> Perhaps they are drip irrigating the entire floor of the artificial forest to minimize evaporative losses?
More or less (saw it on german TV a few weeks ago) - here ( https://www.planet-wissen.de/video-aegypten--ein-wald-mitten... ), if you jump to 01:55 you'll see the small pipes that distribute the water, but it's a bit more than just "drip irrigation" (at 02:34 it's visible that it's more than just a few drops).

Your water needs might drop significantly once the forest is established. Depending on the trees, the established canopy might drop the evaporative losses dramatically.
True, but I think the GP's danans overall point still stands. Household water consumption (and waste) just isn't that much. It takes a lot of households to support a pretty little forest. Maybe a mature canopy increases your efficiency by 50% or more, but you're still working with a pretty small volume of water.

I have heard a lot of things on this subject.
But I never seen a good article saying it's good. Every article I seen saying it's good only use buzzwords, few numbers, but never tell real life numbers, like how many people worked there, how many they produced, how much they sold it, etc...

So have you heard of Sepp Holzer then? He has a number of documentary films
