Nick Ritar’s Milkwood Permaculture is highly recommended if you’re in Sydney, Australia, and want to learn more about these ‘core design principles’ for human settlements and sustainability.
Ritar explains permaculture: “Permaculture is a holistic system of design for human needs. It is most often applied to basic human needs such as water, food and shelter, but it is also used to design more abstract systems such as community and economic structures. Permaculture is sometimes described as the use of ecology as the basis for designing integrated systems of food production, housing, appropriate technology and community development.”
Nick & Kirsten’s Planting Milkwood site is also highly recommended as an indispensable resource on permaculture, sustainability and voluntary simplicity living.
