Very interesting but the article - for me - was too scarce on details of this farming system so I took to google. For anyone who wants a TLDR: This is basically a combination of "forest farming" and "terraforming/re-wilding"
- forest farming uses a mix of different plants with different grow heights so the available are isn't just fully utilized in 2 dimensions but the third as well. This mixing avoids many issues with monocultures, and better protects the ground against the sun.
- the second aspect is using different stages of plants, first to reclaim dead land with primitive but hardy "pioneer" plants, follow them up with "bioaccumulator" plants that have higher needs but are excellent at enriching the land with biomass before culminating in plants that have the highest needs but also support the most diversity and are most productive.
