An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Carbon Farming
-
Management: Standard
Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.
-
Staple Crop: Oil
(0-15 percent protein, 16+ percent oil). Some of these are consumed whole while others are exclusively pressed for oil. Annuals include canola, poppyseed, maize, cottonseed, sunflower, peanut. Perennials include high-oil fruits, seeds, and nuts, such as olive, coconut, avocado, oil palm, shea, pecan, and macadamia. Some perennial oil crops are consumed whole as fruits and nuts, while others are exclusively pressed for oil (and some are used fresh and for oil).
-
Under Development
Plant breeders are actively working to domesticate these plants for cultivation, but they are not yet commercially available as crops. Examples include most of the perennial cereal grains.
