Designing the conditions for health to regenerate.
I'm Cas Tognarini, The Permaculture Nurse. A mental health nurse, permaculture designer and PhD researcher applying permaculture's design logic to how we understand, deliver and experience care.
Why Permaculture?
Health is not a destination, a supplement stack, or a morning routine. It's a living, dynamic, sometimes messy ecosystem that needs good design, honest observation, and the right conditions to regenerate over time.
A decade of mental health nursing showed me where care systems fail people. Permaculture gave me the design language and tools to ask a different question: not how do we treat the person in front of us, but how do we design the conditions they're standing in.
Health is an ecosystem. Tend to it with attention, design it with care, and let it be wild.
The Permaculture Nurse Framework is a living systems model for health, built on permaculture's own zone logic. Traditional permaculture design maps a landscape from Zone 1, closest to home and most tended, out to Zone 5, the wild edge. I extend that frame in both directions.
Zone 00 is the innermost zone: the individual, their nervous system, identity, meaning, and capacity to cope. Zone 6 is the outermost: the village, the community and systems of care that either sustain a person or deplete them. Between them sit the zones permaculture already maps well: home, daily practice, relationship to the living world.
Three mechanisms move through every zone of the framework:
Reconnection.
To self, to nature, to others, to meaning.
Regeneration.
Building capacity over time, not just managing symptoms.
Reciprocity.
The shift from surviving to contributing. From depleted to held.
Where is this going?
Permaculture already has a track record inside health systems internationally. In Malawi, a permaculture garden integrated into a maternity waiting home at Area 25 Hospital has been part of maintaining a maternal mortality rate a fraction of the national average, evidence that designing the conditions around a person changes outcomes, not just treating the person does.
My work is asking the same question inside Australian mental health services. What would it mean to design the conditions for care, not just deliver it. This is what my research and design practice are building toward.

Permaculture for Health Workshop (Coming Soon)
A free introduction to the Permaculture Nurse Framework, where ecological design meets health and wellbeing research.
The nurse. The designer. The researcher. The woman living inside the proof of concept.
About Cas
I'm a mental health nurse with over a decade of clinical experience. A permaculture designer who lives and works on Little Tern Farm, a permaculture property I designed on Yaegl Country in the Clarence Valley, NSW. A PhD candidate researching the intersection of ecological design and mental health. A homeschooling mother of two. A person living with a chronic health condition inside a life I designed to hold it.
I am not sharing you a version of health I read about. I built it. I tend it. I live inside it every day, including the hard days.
