Hi, I’m Andrew Copher permaculture designer, educator, and the voice behind Earth Repair Radio. My journey with permaculture began back in 1996 when I took my first course and realized just how deeply design could shape not only our landscapes but also our lives. Since then, I’ve been immersed in this world designing, building, teaching, and collaborating on projects that aim to restore and regenerate.

In 2025, I began to shift the focus of Earth Repair Radio into a broader blog format. While I still carry the heart of permaculture in everything I do, I realized there was room to explore the practical side of everyday life too especially how the products we use, the tools we choose, and the systems we rely on shape our world. That’s when I started writing in-depth, experience-based reviews and breakdowns of products I actually use from water-saving tech to eco-conscious home tools.
