Donno about perma-guys acknowledging indigenous culture... that's the least they should do.
In Brazil permaculture is losing heat to the #agroforestry movement. But it also suffers from similar problems. The movement's god-figure is Ernst Gotsch, a Swiss farmer living here in Brazilian territory who "originated" these techniques... even though there are many proofs that pre-colombian peoples were responsible for converting savannas into what is today the amazon forest. Also never heard of this movement acknowledging indigenous peoples, instead indigenous peoples have been acknowledging the usefulness of agroflorestry techniques.
It's good that indigenous ways of planting are being revived... but the fact that it's being credited to western people, and turned into western movements makes me believe they'll be too shallow, not encompassing the necessary systematic changes that are necessary for real shift to non-destructive ways of life.
