In this beautiful article by a Kiwi living with his partner Asako in Japan, Dion suggests that:
As perennial forage systems forest gardens are horticultural, they have already left agriculture behind.
Their sufficiency is due in part to the diversity of species and a mimicry of naturally occurring ecosystems but this can be taken much further by adapting ourselves to our garden homes: if you want to eat an agricultural diet then you will continue to need agriculture!
Eating a diet that resembles that of our pre-agricultural ancestors makes feeding oneself from a forest garden that much easier.
UPADTE: Sept 2nd, 2014 – I have just completed a 30 day experiment of eating no grains or grain products (Wheat, Rice, Corn) and no legumes or legume based products (Beans of all kinds), I would concur that this is a very real alternative to relying on an industrial agriculture system, that I sense has had its day and will experience a significant decline in the coming years.
And to clarify this, I am not suggesting we are going to become wild, but sourcing more and more of our food from diverse, balanced, multi-layered eco-systems which focus on mostly perennial production and mimic the principles inherit in a forest, is worth striving for.
