Imagine there is a small island, like Malta, and the ecosystem has no external inputs (no fertilizer delivery, etc).
What does a sustainable plant based agriculture system look like? Are there already existing examples?
I’m very interested in how top soil is maintained without external fertilizer inputs?
One area of concern, I have, with modern monocrop farming techniques is the depletion of top soil, with something like 60 crop cycles left before we are current system falls over.
I just recently got a book on the topic! (The Veganic Grower’s Handbook, by Jimmy Videle)
It’s a fairly deep topic, and I’ve still got a lot to learn, but veganic farming and permaculture is certainly on the rise. There are quite a few small veganic farms spattered all over the place. Iirc, there are several online directories you can find.
Here’s a good resource to check out on the theory behind it:
