Hello
Not sure where you're based but you might be interested in some of the stuff the Permaculture Association are doing in the UK -
https://www.permaculture.org.uk/our-work/research
It's not on the website (should probably fix that!) but I run their 'Permaculture International Research Network', PIRN for short. If anyone is interested in getting involved we're on facebook (
https://www.facebook.com/InternationalPermacultureResearch) or drop an email to:
