I've been following Andrew Millison's work for a while, he's got a lot of really wonderful introductory lessons on permaculture. He's got an online course at the University of Oregon, I'm planning on taking it sometime soon

Fascinating video, but still it worries me how sustainable this is. This isn&#x27;t a &quot;rewilding&quot; process - there is a LOT of manual human labor going into supporting very low yield agriculture.<p>It seems like this idea relies on a long term low wage workforce willing to live on subsistence agriculture.

Very amazing work. Syntropic farming, hadn&#x27;t heard the term before but glad to do more research into it. Also the half-moons is very smart, very interesting. Interesting they went for half-moons instead of swales like in permaculture design, both aimed to increase water-retention. I guess in such very arid conditions half-moons may work better for water retention

Thanks for sharing. Super interesting video. Never spent a lot of time with it, but I&#x27;ve always been curious how people could rebuild an ecosystem.<p>I think it was the dune series, that I read a number of years back that touched on this idea a bit in the second or third book? It was not something I ever really thought about before that. It&#x27;s cool to see a real life example of it.

If you&#x27;re interested in the trials and tribulations of regreening a desert landscape, I recommend this YouTuber with an ambitious dream:<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;@dustupstexas" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;@dustupstexas</a>

Side effect of this in the long term if it is successful is that there should be fewer hurricanes on the Atlantic.<p>(Hurricanes are believed to caused by dust blowing off the west coast of the Sahara)

who is africa<p>also, this is geoengineering. the same kind the soviets used to do and the chinese do now. it would never be allowed to happen in a western country because someone with deep pockets for a lawsuit would find an endangered species of worm living in a dune or two

3 words.<p>&quot;Geoff Lawton videos.&quot;<p>You know, that Strine permaculture guy.<p>Watch at least 15 to 20 of them. Many are short.<p>Only then talk, people.<p><a href="https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Geoff_Lawton" rel="nofollow">https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Geoff_Lawton</a><p><a href="https:&#x2F;&#x2F;youtube.com&#x2F;@DiscoverPermaculture?si=XVjdWpJk5ZIVTnLP" rel="nofollow">https:&#x2F;&#x2F;youtube.com&#x2F;@DiscoverPermaculture?si=XVjdWpJk5ZIVTnL...</a><p><a href="https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Strine" rel="nofollow">https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Strine</a>

I abhor these projects, because they are seasonal- as in dependent on outside funds and thus hyper-fragile. Also usually propped up by colonizers, to detract from some ressource extraction destruction.<p>Same with wildlife preserves. One bad coup with corrupt politicians, one recession in the west - and its all gone, poached and ruins. Its worthless feel good photo OP, monetary potemkin zoos and forrests, providing the worst kind of hope, the one that has no chance to last in a storm.<p>What is their solution against nomads and there goat herds which are still a status symbol and in conflict with the farmers of the region? Poisonous plants? Guards? Landmines? How does it prevent building up resentment, when obviously a green landscape is more important to the foreigners, then the starving locals?<p>How does it solve the hard problem of exponential mankind vs civilizational allmende protection?<p>How do the plants survive in the climate change storms yet to come?
