By the end of this brief tour, you will be able to:
- appreciate that iAVs is the integration of horticulture, soil ecology and aquaculture.
- appreciate that iAVs Sandgardening has a proud heritage…one that is based on science.
- meet the people behind iAVs Sandgardening.
- understand what drives us…our vision!
- read journal and magazine articles relating to iAVs.
Welcome to iAVs Sandgardening.
- Is a symbiotic polyculture – it’s the integration of horticulture and aquaculture.
- Produces food using the metabolic wastes of fish.
- Produces more food for less water.
- Produces clean fresh organic food – anywhere.
- Produces a wide variety of food crops – in any season.
- Allows food production without harm to the planet.
- Infinitely scalable from one to a million square metres.
- Is easy to build and simple to operate.
How It All Started
iAVs Sandgardening had its genesis in the mid-1980s when a product design student at North Carolina State University demonstrated the ‘closed loop’ production of fruit and vegetables using nothing more than the metabolic wastes of freshwater fish.
His peer-reviewed research resulted in the Integrated Aqua-Vegeculture System (iAVs) and enabled its inventor Dr Mark R McMurtry to realise a personal goal – to devise a means by which impoverished villagers could derive their nutrition without harming their environment.
We remain committed to the original premise behind iAVs…to provide impoverished people with the means to grow their own nutritious food without damage to the planet.
Climate change, the pandemic and ongoing conflict, however, are creating food quality and security issues for everyone! Everywhere!
With that in mind, we offer the method to anyone who would like to grow their own clean fresh organic fruit and vegetables – regardless of scale.

Mark R McMurtry PhD
A scientist and CEA horticulturist – the inventor of iAVs – arguably the most productive, resilient and sustainable food production method ever devised.
An urban farmer with 40 years of experience. He manages this website, washes the dishes and carries the bags.
We make bold claims, so we expect (indeed encourage) scepticism …and we offer the following just so you understand that we can prove what we say about iAVs…and that we didn’t just make it all up!

No scientific investigation is done in isolation and iAVs was fortunate in that its investigative team and the advisory body consisted of people who were at the top of their professional careers.
