       | These articles always seem strange to me. There was another story
       | a few years ago, also from Jordan if I recall correctly, where
       | some member of the royal family did some permaculture thing with
       | some Western group. Great success, look at all the plants,
       | amazing, greening the desert and all that, fancy YT videos, and
       | they were celebrating some anniversary.
       | 
       | Now here's another one, and they're creating a forest on 250sqm.
       | 
       | It feels like they're starting over and over, but either there's
       | other successful projects "next door" which the articles never
       | really mention, or the other projects were shut down or failed
       | some time before. Did they? If so, why?
       | 
       | The same thing happens in Saudi Arabia where they had some
       | amazing results by (oversimplified, yes), digging some swales and
       | putting some rocks on steep hills. The grass was coming back,
       | trees were growing. And that's it, cut, no more info. You'd think
       | that this would be naturally adopted by each neighboring
       | community immediately, and the whole desert would be greened in
       | no time. But somehow it isn't. Why?
       | 
       | These countries are fairly autocratic, and obviously these
       | projects have the blessing of the rulers, or they wouldn't
       | happen, and surely the rulers would love to have the forests
       | restored and the desertification stopped and all that, and it
       | makes for great photo ops, too. Why then, don't they decree these
       | projects to happen at scale?
       | 
       | I'm not saying it's all bullshit, maybe it's just journalists who
       | need a new story every other years, but these are, to me, obvious
       | questions, that I'd answer if I was writing an article about
       | these things, and it's suspicious that they aren't being
       | answered, ever.

         | You are probably talking about Al Baydha. As far as I
         | understand, the project ran 2009-2016, and last information in

             | These systems work. They scale (which is not surprising
             | when you think about it, they are made of four-billion-
             | year-old self-improving nano-technology that optimizes for
             | exponential reproduction at all levels simultaneously, aka
             | "life".)
             | 
             | If there's one systemic problem it's that Permaculture is
             | diametrically opposed to _extractive_ economic systems.
             | (E.g. modern agriculture is /was more akin to mining than
             | ecosystem design.) Monsanto (just to pick on them) has no
             | place in a tessellation of ecological small-holdings.
             | 
             | Another factor is that many Permies elect to charge money
             | to teach Permaculture, and even the main textbook
             | "Permaculture: A Designer's Manual" has been scarce on the
             | ground and hard to get for years. I think it's a little
             | better now? You can order it online and get it delivered. I
             | think Permaculture et. al. would have spread faster if
             | people taught it for free (and made money from selling the
             | surplus they developed on their Permaculture farm, eh?)
             | 
             | These days it has reached "critical mass" and the concepts
             | of applied ecology are rolling out all over. You can search

             | example.

           | I spent quite a bit of time embedded in the Permaculture

           | read all the key Permaculture texts (both volumes of Edible
           | Forest Gardens, Mollison's original Permaculture: A
           | Designer's Manual, and many more).
           | 
           | They do not mesh with ecological science.
           | 
           | The problem with Permacultrure is that if you pay attention
           | to the design system, it's effectively a return to pre-
           | science individualistic naturalism. It's entirely based on
           | individual personal observation, and removes a lot of the
           | checks against personal bias that science introduced to
           | improve upon individual naturalism.
           | 
           | Thus it's entirely possible for a Permaculturist to observe
           | invasive species doing useful things for their ecosystem and
           | completely miss all the damage they're doing. It's easy to
           | see the the squirrels who use the Honeysuckle for cover and
           | the birds eating its berries and completely miss all the
           | Lepidoptera species that would be eating the plants the
           | Honeysuckle displaces, and all the birds that depends on
           | those species for protein. This is what Permaculturists
           | _consistently_ miss, but the ecological science is very clear
           | about. Invasive species do far more harm to their biospheres
           | than good.
           | 
           | So when Permaculturists discount controlling those species
           | they are failing to do the very thing they claim to be
           | attempting to do: build healthy ecosystems.
           | 
           | All too often with Permaculture it's much worse than just
           | writing off the need to control invasives. I have seen
           | Permaculturists become so obsessed with designing novel
           | ecosystems that they even introduce invasive species.
           | 
           | The goals of the Permaculture movement - building a society
           | that exists in harmony with the natural world and is thus not
           | only sustainable, but regenerative - are sound. Many of the
           | ideas - building agricultural systems that act like
           | ecosystems - are good and worth exploring. But the methods
           | and approaches taught by Permaculturists in PDC courses are

           | 
           | The mainstream view can probably be described with some
           | quotes from the review process of one their early (submitted
           | 2010, published 2013) papers:
           | 
           | NOAA's Isaac Held:
           | 
           | "The authors make an extraordinary claim that a term that is
           | traditionally considered to be small, to the point that it is
           | sometimes neglected in atmospheric models and, even when not
           | neglected, rarely commented on, is in fact dominant in
           | driving atmospheric circulations. The effect concerned is
           | that of the mass sink associated with condensation. This term
           | is of first-order importance in some planetary atmospheres,
           | such as Mars, where the total mass of the atmosphere has a
           | substantial seasonal cycle, but for Earth the standard
           | perspective is that the heat release associated with
           | condensation dominates over the effect of the mass loss."
           | 
           | Editor's decision:
           | 
           | "The authors have presented an entirely new view of what may
           | be driving dynamics in the atmosphere. This new theory has
           | been subject to considerable criticism which any reader can
           | see in the public review and interactive discussion of the
           | manuscript in ACPD. Normally, the negative reviewer comments
           | would not lead to final acceptance and publication of a
           | manuscript in ACP. After extensive deliberation however, the
           | editor concluded that the revised manuscript still should be
           | published - despite the strong criticism from the esteemed
           | reviewers - to promote continuation of the scientific
           | dialogue on the controversial theory."
