What they cover
Andrew Millison is a permaculture instructor at Oregon State University whose YouTube channel (2M+ subscribers) covers water harvesting, food forests, terracing, and landscape-scale permaculture design. His videos document real projects around the world: ancient water systems in India, reforestation in China's Loess Plateau, and urban food production in Detroit. Production quality is high, with aerial footage and clear diagrams explaining each system.
Why they matter
Millison's channel has done more to mainstream permaculture on YouTube than any other creator. His video on China's Loess Plateau restoration (60M+ views) showed a global audience that desertified landscapes can be restored at continental scale. He bridges academia and practice: his university credentials give the content scientific credibility, while his accessible presentation makes complex ecological design understandable to beginners.
