It must be stated at the outset that I regard permanent agriculture as a valid, safe, and sustainable, complete energy system. Permaculture.^as defined here, claims to be designed agriculture, so that the species, composition, array and organization of plants and animals are the central factor. In that sense this is not a gardening book.
Permaculture One may thus be the first book on plants in which functional design (not cosmetic array) is the central theme; for we have many more energy benefits from design than we have from random placement of species, beyond the intrinsic value of plants or animals.
Perrnaculture Two attempts to make practical suggestions as to how these energy benefits are to be obtained, from domestic to broadacre environments. Plants are not only beneficial of themselves, but also modify local climate and many forms of pollution. Permaculturc is a dispersed system, available to anybody who can garden. Centred on human settlement or community, it holds the welfare of man and the needs of the people it is intended to serve as the paramount concern. The intention of P.I1 then, is not to define a particular solution or to list designs for all climates and occasions, but to instance the ways in which people have evolved new approaches and solutions—most of them needing minimal energy, and all of them producing more calories than they consume.
Permaculture now has had many trials throughout Australia, in many climatic regions. Neither David Holmgren nor myself anticipated the strong response to P.I. and the subsequent demand for detailed planning and lectures, workshops and seminars, consultancy and on-site design.
Many people wrote to say they were practising, or thinking of, similar systems, and that we had expressed their almost-formulated ideas in P.I. which was a hurried re-make of our rather stuffy notes, and it is with more leisure and pleasure that this second book is planned and written. As it cannot cover all cases, or climates, local adaptations will need to be made by readers, but the idea of planning for low-energy systems should be clear.

I hope and believe that the systems presented here will be eclipsed by more carefully designed arrays as we gain experience and information by working with whole systems.
