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.

Other Uses
Adhesive Cosmetic Gum
Other Uses: A glue-like substance is obtained from the tuberous roots[46 ]. A very strong glue with great tenacity[46 ]. It is used for cementing parts of musical instruments such as guitars and mandolins[46 , 345 ]. The glue is prepared in different ways. The simplest method is to simply split the rhizomes and then rub the pulp on the surfaces to be glued[579 ]. Alternatively, when the rhizomes are first cooked and then finely grated, they are said to have great tenacity[345 , 579 ]. The water extraction of the plant gives a gum which is separated by precipitation with alcohol. This gum has exceptional strength and lasting power[579 ].
