This is an excellent idea, much needed and long overdue! If this takes off, then it'll be an important part of a sustainable future (along with the transportation technology to make the swaps possible, of course.)

It's not clear from looking at the site whether this is for exchanging seeds too. Seeds are much easier to transport, so it makes sense to also include listings for seeds. I recommend asking people to indicate what time year their seeds are available, as many seeds have a short viability.

Another important inclusion would be information about transporting seeds and plants long distances. That could include guides on how to prepare and pack them as well as information about seed-/plant-friendly transportation services in various parts of the world. I think that people who offer such a service (and can provide proof of it) should be allowed to make a listing for their service as well.

There's a lot of potential here! If you like these ideas, I'll gladly discuss further over DMs. :)

As others have said, this article is not very accurate. Annual crops produce over a short window, so one would need to have successive crops lined up in order to keep the space productive. Growing something to get only one harvest is a very poor return on investment. If one wants to survive without depending on "the system" at all, then trying to do so outside of the equatorial zone is living life on hard mode.

Near the equator, one could survive on only bananas for a while, and that would take a small fraction of a hectare, probably about as much space as this article talks about, but realistically, eating only banana long-term is not feasible, and growing more variety requires more space. There is also the feast-or-famine issue if the gaps between harvests are too long. Preservation of the harvest is time-consuming and requires infrastructure that not everyone has (e.g. refrigeration). Living in a neighbourhood where everyone is growing food in order to survive would allow for trade, and so each individual/household would not need to diversify their food production as much, and someone's excess that they cannot preserve could fill someone else's harvest gap, reducing the total amount of land that each requires. Ideally, that's the way to do it, and some people are trying. Tree fruits make the most sense as staple foods, since they become self-maintaining after a few years (other than pruning to control size), and in a sufficiently diverse food forest ecosystem, the trees won't deplete the soil or invite plagues, so they don't require externally-produced fertilisers and -icides. With enough different species and a fairly non-seasonal climate, it's possible to grow enough fruit year-round, with some high-calorie staple(s) always in season.

But lettuce and lima beans? Good luck with that.

For transporting grafted plants in luggage (in order to get them through customs), this video explains the process of removing soil, bracing graft union, and so on.

All systems of oppression must be dismantled, no matter how inconvenient or unpleasant that process may be.

This article was (from what I understood) mostly referring to old heirloom crops that are no longer widely grown because they've been superseded by newer commercial cultivars. I remember hearing that in the early 1900s, there were something like 53 potato cultivars available to buy in grocery stores in the USA, but by the end of the century, there were only 4. That probably applies to other crops as well. Another example of capitalism reducing biodiversity, I guess.

I think that the point of the article is that keeping a large seed collection in storage is a risk; if the freezer fails, all of those seeds are lost forever. Even if the seeds are preserved indefinitely, after a few centuries of climate change, they may not be able to survive in the same region where they were collected, whereas by growing them out generation after generation, they are allowed to adapt to changing conditions and maintain a different sort of viability.

It would seem that keeping some seeds preserved in cold storage while also growing some of the same lineage in as many locations as possible would be the most effective means of keeping the genetics alive.

Someone has to be the first.

The article is definitely lacking details about the Moche and Chimu cultures. The coast of Peru has a history of severe droughts and floods and landslides and earthquakes, yet these people had advanced irrigation systems and managed to live in such an environment for centuries. From what I understand, it's the communal management and temporary nature of the irrigation infrastructure that differs from modern methods, but the how of managing it and moving it over time is left out. If anyone knows more, perhaps they can comment here.

Doesn't need to be a desert. Anywhere that has a dry season with lower humidity should work regardless of total annual precipitation.

And borax, to keep the termites from eating it.

One more reason to move to the jungle.

Just be to sure to check for rotten spots in an old wooden barrel before setting it up! Old wood + constant moisture = fungal rot.
