Permaculture One is probably the book that started the world-changing movement that is permaculture. It was speculative in nature when written but like all permaculture was based on intense observation and the practicalities of land-use. I would thoroughly recommend it for anyone embarking upon a journey of sustainability. It’s hard to believe that Permaculture One was published in 1978 - the ideas are as fresh today as they were then.
