Permaculture Principles, Ethics and Zones Explained
Permaculture principles are a set of ideas for designing land, gardens and farms that produce food while looking after soil, water and wildlife. Permaculture is a design framework, not a single planting method. It rests on three ethics, twelve design principles and a way of placing things on a property called zones. This post explains each part in plain terms, shows how the ideas apply to Australian land, and ends with a starting guide for permaculture for beginners.
What Is Permaculture?
Permaculture was developed in Australia in the 1970s by Bill Mollison and David Holmgren, and their 1978 book Permaculture One set out the idea. The word began as a short form of "permanent agriculture". It later came to mean "permanent culture", because the ideas cover how people live as well as how food is grown.
In practice, permaculture is a way of making design decisions. A designer studies a site, works out what the people using it need, and arranges plants, water, buildings and animals so that they support each other. It does not prescribe one layout, one crop or one technique.
That is why permaculture sits above more specific methods. Syntropic agriculture, food forests and edible landscapes can all be carried out inside a permaculture design. A property can also use permaculture without using any of them. Regenerative agriculture is broader again. It describes outcomes such as healthier soil, better water cycles and more biodiversity, and permaculture is one of several ways to reach them.
Permaculture Ethics: The Three Values Behind Every Decision
Permaculture ethics are the values that guide every design decision. There are three.
Earth care. Look after the soil, water, plants and animals that the property depends on.
People care. Meet the needs of the people who use the land, including food, shelter, health and community.
Fair share. Take only a fair portion of what the land provides, and share any surplus.
The ethics work as a check on a design. A design that gives a large harvest but damages a local creek fails the first ethic. A design that protects the land but adds too much work for the people living there fails the second.
The Twelve Permaculture Principles
The twelve principles most often taught were set out by David Holmgren in his 2002 book Permaculture: Principles and Pathways Beyond Sustainability. Bill Mollison used a different set of principles in his earlier Permaculture: A Designer's Manual. The principles are thinking tools, not rules. Each one suggests a question to ask before making a decision. A summary of the principles is on the permaculture principles website.
Observe and interact. Watch how the site behaves before changing it, and adjust the design as more is learned. Sun, water flow and frost pockets are the first things to look at.
Catch and store energy. Collect resources when they are plentiful. Examples are rainwater in tanks and dams, sunlight in plant growth, and cuttings kept as mulch.
Obtain a yield. Each part of the design should produce something useful, so the effort put in is rewarded.
Apply self-regulation and accept feedback. Notice what is failing and change course, rather than repeating what does not work.
Use and value renewable resources and services. Let natural processes, such as nitrogen-fixing plants and pollinating insects, do work that would otherwise need bought inputs.
Produce no waste. Treat the output of one part of the system as the input of another, such as pruning becoming mulch.
Design from patterns to details. Start with the large patterns of a site, such as slope, water flow and climate, then fill in the details.
Integrate rather than segregate. Place elements so that they support each other, such as a water tank that serves several gardens.
Use Small and Slow Solutions. Start small and build in stages. Small systems are easier to maintain and to correct.
Use and value diversity. A mix of species and functions spreads risk, so one pest, frost or dry spell does not damage everything.
Use edges and value the marginal. The boundary between two areas, such as forest and paddock, often holds more variety and can be productive.
Creatively use and respond to change. Plan for changes in climate, plants and the people using the land, and work with natural succession instead of against it.
Several of these show up clearly in syntropic agriculture. Succession is a way of using change, and chop and drop returns cuttings to the soil as mulch instead of treating them as waste.
Permaculture Zones: Placing Things by How Often They Are Used
Permaculture zones organise a property by how often people visit each part. Things that need frequent attention go close to the house. Things that need little attention go further out. The aim is to save time and effort, because a kitchen garden that is a long walk away tends to be neglected.
Zones are usually numbered 0 to 5.
Zone | Typical contents | Attention needed |
0 | The house | Daily use |
1 | Kitchen garden, herbs, salad greens and compost | Visited daily |
2 | Fruit trees, berries, larger beds and small livestock | Visited regularly |
3 | Main crops and larger plantings, for household use or sale | Seasonal work |
4 | Managed semi-wild areas for firewood, foraging and timber | Occasional visits |
5 | Wilderness, left largely unmanaged | Visits to observe only |
Few properties match the neat circles of the textbook diagram. Slope, water, existing trees and access shape the real layout, and a small suburban block may only have the first two or three zones.
Sectors: Forces From Outside the Property
Zones describe what people do on a property. Sectors describe forces that arrive from outside it: sun, wind, water flow, frost, bushfire and wildlife movement. In the southern hemisphere, a north-facing slope receives the most winter sun. Cold air also drains downhill and settles in low areas, so frost-tender plants usually suit slopes or sheltered spots better than hollows.
Bushfire is a sector on many Victorian properties. In Australia, Country Fire Authority (CFA) guidance and local council rules drive design here.
Zones and sectors are laid over each other on a site map to decide where things go.
An Example: Project Genesis
Project Genesis is a half-acre regenerative design pilot on a four-acre block in the Macedon Ranges, begun in June 2023. The land was heavily compacted clay. The design combines contour rows spaced six metres apart with one-metre swales and berms, which catch and slow rainwater, and it uses syntropic succession principles for the planting. Of 210 indigenous plants installed, 197 were alive after the first year, and more than 150 are thriving in 2026. The project is an example of Zone 3, as a system like this have potential for producing excess for sale.
The project shows how several principles turn into physical features: swales catch and store water, the planting mix uses diversity, and survival counts give feedback on what is working. The Project Genesis page has more detail.
Permaculture for Beginners: Where to Start
A beginner does not need a large property or a full design. These steps suit most sites.
Observe first. Many permaculture teachers suggest watching a site through a full cycle of seasons before making large changes. Notes on where water runs, where frost settles and where the sun falls prevent costly mistakes.
Start close to the house. A small zone 1 garden that is used every day teaches more than a large planting that is rarely visited.
Catch water. Tanks, mulch and shaping land to slow runoff make later plantings easier. Dams and earthworks can need council or water authority approval and qualified contractors.
Build soil with cover and mulch. Keep the ground covered and return organic matter to it. The post on soil regeneration explains how this works.
Choose plants that suit the local climate, and check weed lists. Some useful plants are environmental weeds in parts of Australia, so each species should be checked against state weed lists.
Add perennial plants in stages. Trees, shrubs and other long-lived plants can be added as the first plantings establish.
Learn locally. Local permaculture and Landcare groups share knowledge of what grows well nearby. The usual formal training is a Permaculture Design Certificate (PDC) course.
Ecologic Solutions provides permaculture design for rural and peri-urban properties, on site in Australia and remotely worldwide. Each project starts with an assessment of the site's climate, soil, water and goals.
Frequently Asked Questions
What are the three permaculture ethics?
Earth care, people care and fair share. They are the values that guide every design decision.
How many permaculture principles are there?
Twelve in the list most often taught, written by David Holmgren in 2002. Bill Mollison's earlier list differs slightly.
What are permaculture zones?
A way of placing things on a property by how often they are visited. Zone 0 is the house and zone 5 is unmanaged wilderness, with zones 1 to 4 in between.
Is permaculture the same as organic farming?
No. Organic certification sets rules about which inputs may be used. Permaculture is a design approach with no product certification of its own, although many permaculture designs avoid synthetic chemicals.
Is permaculture the same as syntropic agriculture?
No. Permaculture is the wider design framework. Syntropic agriculture is a specific planting and management method that can be used within it.
