THIS IS NOT A BOOK solely about techniques to enable people to become better gardeners, nor is it a textbook for a Permaculture Design Course. There are already many books that fill those roles. This is a book about strategies, some techniques and useful information about plants, technology and materials. As a scientist, I am interested in facts, numbers and statistics, so you may be surprised to read about only particular plants, and I have endeavored not to make too many unsubstantiated claims. I have tried to present factual information rather than fable, provided some elaboration on how things work in the world, and attempted to make a complicated and complex world a little easier to understand.
