Obtain a Yield
Design for useful returns that sustain people and the work while examining whose needs are met and what costs make the yield possible.
Definition and orientation
Obtain a Yield keeps design connected to present needs and useful returns. A yield may be food, water, shelter, learning, health, habitat, income or another benefit, but naming it is only the beginning. Designers should establish who values it, when it is needed, whether it is sufficient, and which inputs, risks and opportunity costs accompany it.
What it guides: the principle helps frame design judgement through questions such as:
- Which immediate and longer-term returns are genuinely useful?
- How will quantity, quality, timing and distribution be recognised?
- What inputs, displaced uses or harms could make the apparent yield misleading?

Obtain a Yield: a contextual design lens
- NeedName the recipient, purpose, timing and threshold.
- YieldIdentify tangible and intangible useful returns.
- CostAccount for labour, materials, risk and ecological effects.
- LearnCompare the return with the need and adapt the system.
Origins, lineage and attribution
This wording belongs to David Holmgren’s twelve-principle formulation. Holmgren published the set in 2002 and describes the principles as memorable thinking tools that open different perspectives into whole-systems design. He also states that methods vary with place and situation and that principles do not substitute for practical experience or technical knowledge.
The Academy’s explanation is an attributed teaching interpretation, not a reproduction of Holmgren’s icon or a claim that Mark originated the principle. Other permaculture lineages may organise similar ideas differently.
Ethical and principle context
Caught and stored energy can support yields; Needs and Yields Analysis makes inputs and outputs visible; No Waste may turn one output into another element’s input. Ethics and Self-Regulation constrain pursuit of a yield when benefits are unfairly distributed or gained through depletion.
Use Earth Care, People Care and Fair Share to test purpose, consequences and distribution. Apply this principle with at least one counter-question, relevant evidence and a named review point. It should influence judgement without becoming a slogan that certifies a preferred decision.
When and how to use it
- Name the decision, scale, affected people and living systems.
- Turn the principle into one or more open questions suited to the context.
- Add a counter-question that could expose harm, urgency, maintenance or a conflicting principle.
- Use a relevant framework or tool to gather evidence; do not mistake the method for the answer.
- Choose a proportionate action and state what remains uncertain.
- Record what evidence or feedback would trigger review, adaptation or stopping.
Application in Mark’s Diploma and at Vila Pinheiro
Design 05’s maintenance stage proposes checking water quality and developing a natural pond intended to support fish, ducks, irrigation and fertility. The same page proposes diverse, drought-resistant planting for food, fuel and fibre. These are intended multiple yields in a design document, not verified production totals or proof that aquaculture was established.
Evidence boundary: this representative connection was checked in Mark D’Cruz, Design 05: Water Self-sufficiency with Attachments, controlled Diploma PDF, PDF page 28. The master register also records broader use across Designs 1–10; those additional declarations are not converted here into unverified public case claims.
Limits, critiques and common misuse
- Equating yield only with saleable output or maximum short-term production.
- Counting a planned benefit as though it had already occurred.
- Ignoring unpaid care, imported fertility, pollution or risk behind a reported return.
- Using the principle to justify extraction without Earth Care, People Care and Fair Share.
A principle cannot replace consent, law, site-specific evidence, competent technical advice or accountable maintenance. When principles pull in different directions, make the tension visible rather than selecting only the phrase that supports an existing preference.
Where this material comes from
This page follows Principle 3 in David Holmgren’s twelve-principle formulation, published in Permaculture: Principles and Pathways Beyond Sustainability (2002). Its principal sources are Holmgren’s Essence of Permaculture and the author-led Permaculture Principles publication. Holmgren presents the twelve as connected systems-thinking and design-thinking tools whose expression varies with place and situation. Related phrases and overlapping ideas appear in other permaculture traditions, but this page neither transfers their authorship to Holmgren nor flattens their differences. Mark D’Cruz used and interpreted this principle in his Diploma work; he is not its originator, and the master register records it as LIB-030. The authoritative formulation has been checked against Holmgren’s published explanation. The representative Diploma connection is verified at PDF page 28, with proposed actions and outcomes kept explicitly distinct.
