While many Sydneysiders escaped the big city over Easter, a national permaculture conference was held with people lining up to learn about innovative ways of farming and backyard gardening.

A key speaker at the Australian Permaculture Convergence was the co-founder of permaculture, David Holmgren.

David originally developed the concept during the oil crisis of the 1970’s.

Now with peak oil, he says permaculture is more relevant than ever.

Environment reporter Phil Stubbs caught up with him at the conference.
