To get the overview of what a permaculture farm is and how it is developed we recommend, Restoration Agriculture by Mark Shepard. He is the founder and manager of New Forest Farm in southwest Wisconson, USA.
Every farm is going to be different based on the climate, soils, water issues, and the owner’s goals and purpose for creating a permaculture farm. The single most important issue in establishing a sustainable permaculture farm is water management. All food producing plants require water. The ability to provide a stable and sustainable supply of water to your plants is of critical importance. To achieve this requires foresight and planning and may involve engineering in challenging sites. As a guide and resource for understanding how to develop a sustainable water supply we recommend, Water for Any Farm by Mark Shepard. This book is technical and covers the details of how to plan and implement a sustainable water system on the site.
Both books are available in audio format and hard copy.
