Permaculture diploma tutor, Wilf Richards, explains why we need to evolve the original permaculture principles.

Permaculture was first introduced with Bill Mollison's principles, and then followed by David Holmgren's 12.

But as Wilf explains, permaculture has evolved since the 1970s, and with it the principles have too. Many practitioners have added to the well of permaculture knowledge helping to add and adapt the founding principles.

Wilf shares this evolution and collaborative knowledge in his new book, The Power of Permaculture Principles.
