What's Permaculture All About?

What It Covers

Permaculture, coined in 1978 by Australians Bill Mollison and David Holmgren from "permanent agriculture," offers a design framework for growing food sustainably by mimicking natural ecosystems. The episode covers its three core ethics, ten design principles, scientific comparisons to conventional gardening, and practical urban backyard applications.

Key Questions Answered

• •Zone Planning: Divide land into concentric zones based on required human attention, placing high-maintenance crops closest to the home and allowing progressively wilder growth outward. Before planting anything, spend a full year observing sun patterns, wind direction, water flow, and animal movement to build an accurate zone and sector map.
• •Multi-Function Design: Every element should serve at least three purposes simultaneously. A pond irrigates crops downhill via gravity, waters livestock, and acts as a natural fence barrier. A hedge blocks wind, produces seeds for chickens, and provides shade. Designing for multiple functions eliminates the need for external inputs like pumps, fencing, and feed.
• •Biological Pest Control: Rather than purchasing lab-raised ladybugs online — which frequently carry parasites that devastate native populations — plant high-pollinating species like sunflowers to attract native, parasite-free ladybugs that naturally control aphid infestations. Similarly, rotating pigs through future cropland tills and fertilizes soil without mechanical equipment.
• •Yield vs. Resilience Tradeoff: A UK study at Schumacher College found conventional gardening yields 13 kilograms of edible food per 100 square meters versus 2.3 kilograms for permaculture plots. However, permaculture required significantly less labor and maintained consistent yields during a bad-weather year when conventional plots suffered measurable losses.
• •Swale Water Management: Installing a level ditch or small pond with a surrounding berm stops rainwater runoff and forces slow ground absorption, recharging soil moisture rather than losing water to drainage. Connecting roof gutters to an underground cistern and routing overflow into a swale creates a gravity-assisted irrigation system requiring minimal electricity input.
