Healthy Food Association: Registry of Coaches

Healthy Food Association: Registry of Coaches

This registry is a simple public list of coaches connected to the Healthy Food Association. Coaches provide their own details by email, and the registry helps connect members with people who can offer practical guidance. Coaches are responsible for the accuracy of their information, and any paid work is arranged directly between the coach and the member. The registry is provisional and will be updated as more coaches provide information over time.


Introduction

The Registry of Coaches exists to make it easier for people interested in healthy food and practical growing systems to find support. It is published by the Healthy Food Association as a straightforward list of registered coaches. Coaches are not approved through a complex process. Instead, they submit their own details in a consistent format, and those details are placed on the registry.

The aim is simple: to bring coaches and users together in one place without making the registry owner responsible for verifying each listing. This keeps the system easy to manage and allows it to grow steadily over time.

What This Registry Is

This document is a list of registered coaches for the Healthy Food Association. It acts as a shared reference point so members can locate coaches by state and read the information each coach has supplied.

The registry is described as a provisional publication. This means it is an early release that demonstrates the format coaches are advised to use. As more coaches submit details, the registry can be expanded and updated.

How Coaches Get Listed

Coaches are listed by emailing their details to the registry contact. Once received, those details are published using the advised format. This approach avoids complex forms or platforms and keeps participation simple and accessible.

Coaches submit their information by emailing colinaustin@bigpond.com.

Responsibility and Boundaries

The registry makes two responsibilities very clear. First, the coach is entirely responsible for the accuracy of the information they provide. The registry publishes information but does not act as a verification authority.

Second, any commercial arrangement is strictly between the coach and the member. This includes pricing, scope of work, payment terms, and outcomes. The registry does not act as a broker or intermediary. Members are encouraged to ask questions, confirm expectations, and agree on terms directly with the coach before beginning any paid work.

States and Regions

The registry groups coaches by state and territory to help members find local or regional support. The structure includes New South Wales, Queensland, South Australia, Victoria, Western Australia, and the Northern Territory.

This regional structure is especially useful where coaching involves site-specific advice, construction guidance, or local growing conditions.

Recommended Coach Entry Format

The registry includes a sample coach entry to demonstrate the recommended structure. This helps maintain consistency and makes entries easier to read and compare.

The sample entry is listed under Queensland and provides a practical example of how coaches should present their information.

Sample Coach Entry — Queensland

Name

Colin Austin.

Address

55 Kookaburra Park, Gin Gin, Queensland 4671.

Telephone

07 4157 2278.

Experience and Background

The sample entry outlines a background combining engineering, technology development, and long-term research into soil regeneration and food systems.

Colin Austin is an engineer who developed Moldflow technology and built one of Australia’s leading exporters of technical software. He was internationally recognised as a leader in computational fluid flow.

His research into soil regeneration began in the 1970s, leading to the development of wicking bed technology in 1995. Personal health experiences, including recovery from a triple bypass and supporting a partner living with diabetes, reinforced a long-term commitment to healthy food systems.

Wicking Beds Constructed

The sample entry explains experience across a wide range of wicking bed designs, including small boxes, open and closed beds, and wicking furrows.

Ongoing experimentation includes sponge bed systems intended for larger-scale use. This practical experience is important because successful wicking beds depend on correct construction, soil structure, and long-term water management.

Services Offered

General advice on wicking bed construction and use is provided online and is offered free of charge.

This clear service description helps members understand what support is available and how it is delivered.

Products Offered

The sample entry lists two products designed to support soil regeneration and small-scale food production.

Bio-packs include host plants for mycorrhizal fungi, selected worm eggs for soil regeneration, and micro-nutrients, priced at $25.

Small wicking bed boxes incorporating bio-packs and selected plants are listed at $40.

Websites

The sample entry includes multiple websites that provide background information, technical explanations, and related resources.

Email Contacts

Two email addresses are provided to allow direct contact and discussion of specific needs or questions.

Using the Registry Effectively

Members are encouraged to approach the registry with clear goals. Before contacting a coach, it helps to understand what type of system is being built, local climate conditions, available space and materials, and desired outcomes.

Clear starting information allows coaches to give more precise advice and reduces misunderstandings.

Keeping the Registry Current

The registry is designed as a living document. As more coaches submit information, entries can be added or updated using the same format.

This simple structure makes the registry easy to maintain while supporting steady growth.

Conclusion

The Registry of Coaches is a practical tool for connecting people with knowledge and experience in healthy food and growing systems. Coaches provide their own information, and members engage directly with them. The registry does not verify listings or manage commercial relationships.

By keeping the system simple, clear, and open, the registry supports learning, reduces barriers to action, and helps people build better systems with confidence.

De-Boggling China: Food, Farming, and Health in a Rapidly Changing World

Halfway through a trip to China, Colin Austin is “de-boggling” — trying to separate real insights from quackery while looking for Chinese herbs, medicinal plants, and vegetables that people could grow in wicking beds to improve health. China is changing at a mind-boggling pace: soaring wealth, massive manufacturing regions, huge migration, and growing diabetes exist side by side. Along the way, odd clues—like bulk toilet paper purchases and frequent toilet trips—raise deeper questions about diet, soil, and what makes people healthy.


Introduction — De-Boggling

Well I am half way through my China trip — busy de-boggling. One aim of the trip was to look for Chinese herbs, medicinal plants and vegetables which people could grow in their wicking beds to improve their health.

I thought it may be difficult to find these plants but the opposite is happening. The problem is not to find the plants but rather to work out what is quackery and what is real — after all this is the country that believes eating rhino horn increases male potency, a fantasy of wishful thinking and envy. But more of that later — let’s get boggling.

I only know two things for sure about China: if you think you know what is going on you are probably wrong and suffering from a delusion, and in the remote possibility that you may just be right it makes no difference anyway as they will change everything in six months.

In my last newsletter I talked about the explosion in obesity and diabetes in China — how it has changed from a country in which obesity and diabetes were rare to one with reportedly the world’s largest problem with diabetes (just having pushed past India, which still pips the USA and Australia).

As I investigate I realised I needed to take a much broader view of what is happening in China. This can only be described as mind boggling and will have dramatic impact on the rest of the world.

That’s a Bit Weird — Pre-Science

Many of the great discoveries have come from someone noticing something out of the ordinary — just a bit weird — without any real science. Then later science cuts in with its classic processes: double blind experiments with statistical analysis to support or refute the observation.

Penicillin, stainless steel and high pressure steam engines are examples. I call this pre-science and was the process I am using. In reality it simply means looking around for anything unusual.

For example, I watched people come out of the supermarket and was struck by the huge amount of toilet paper they were buying. Was this significant? They may have been stocking up, but Chinese people tend to shop more frequently than in the West, so maybe something else was going on.

Then I noticed I was going to the toilet much more frequently than back home. I was living in a normal Chinese family home eating a pretty normal Chinese diet. Yes — Chinese food is a natural laxative so residence time is cut down. I could not help contrasting this with the US where every other advert seemed to be for a laxative.

Was this significant or not? In that classic phrase at the end of nearly every research paper — this needs further investigation.

Shenzhen — Not What You Expect

I am living in Shenzhen (just over the border from Hong Kong). I first visited Shenzhen some thirty years ago as Deng Xiaoping was opening up China. At that time it was little more than a rural village and pretty primitive.

It is now transformed into a mind boggling mega city. I walk out into the street and it is full of upmarket German prestige cars: BMWs, Audis, Porsches and Mercedes. There is the odd Bentley and yesterday there was an Aston Martin in our parking lot — maybe the real James Bond.

Not what you expect in a developing country.

China — The Upside: Stability, Education, and Scale

But China is not a developing country. It is a single country politically, but a sociologist would say it is an aggregate of multiple states, with each state bigger than most countries.

The history of China is one of conflict and corruption. Among the great achievements of the current Government is achieving peace and stability. I hear very little discussion about politics — people look to the Government to provide ongoing increases in prosperity. It will be interesting to see what happens as environmental issues like ubiquitous air pollution become better recognised.

In the early ‘opening up’ phase, technology was imported via overseas companies and joint ventures. But the era of relying on overseas technology is over. The Government has built an advanced education system pumping out qualified people, particularly engineers, on a vast scale. The pressure on my Chinese granddaughters (acquired when I married Xiulan) to perform in this environment is intense: work work work for the poor kids.

President Obama once discussed manufacturing Apple products in America with Steve Jobs. Steve commented he needed some 3,000 qualified production engineers for the iPhone — in China those positions were filled within a month, but he could never do that in the US.

Many Chinese gained experience in overseas firms and became entrepreneurs, designing and manufacturing innovative products in China. My acquired son and friends have set up a business making smart phones — I have one and prefer it to my Samsung S4.

The 150 km corridor along the Pearl River from Shenzhen to Guangzhou houses a population some four times that of Australia and contains much of the world’s electronic manufacturing industry, plus automotive and consumer goods. It brings in huge wealth, though not evenly distributed.

And it is only one region among many: Fujian, Shanghai, Beijing, Manchuria, Chongqing, each the size of a significant country. The manufacturing capacity is mind boggling and can supply the world with manufactured goods.

Roses and Honey — The Human Cost

But it is not all roses and honey. Many people have moved from rural areas to these regions but are legally classified as from another state, so they miss out on services and civil rights provided to locals (they even talk about having a passport). They often live in factory dormitories, work long hours for basic pay, and people begging or sleeping under bridges are common.

Local people call them migrants even though they are ethnic Han Chinese. This mass movement is the largest migration in human history — hundreds of millions of people. Throughout history, from the Romans to the British then the US and now China, wealthy countries have benefited from a pseudo slave population.

How China Builds Industries

The Government has tried to reduce the flow into mega-cities by establishing major industries in rural areas. The pharmaceutical industry is one example. This is not a simple incentive scheme: first build research and educational centres, then provide modern factories at nominal rents, remove legal and financial obstacles, and gear the financial system to assist companies aligned with Government plans.

This is more than the interventionism criticised by right wing politicians; it is cooperative pro-actionist on a grand scale. The banking system is owned or controlled by the Government, which gives it enormous leverage.

Personal Reflection — Risk in the West

This hits home hard. I built Australia’s leading exporter of technical software — profitable and successful — but I had to give $4 million of personal guarantees. When the first Iraq war started, our sales stopped and we could easily have been wiped out, leaving me personally bankrupt. It is difficult to repay $4 million by putting your cap out on the pavement and playing a violin outside a railway station.

My company was later absorbed into a giant American conglomerate with little benefit to Australia. It is easier for entrepreneurs in China; I meet overseas Chinese returning home because business is simpler. Companies fail in China too, but the penalties are less severe and entrepreneurs can start again.

Basket Case to World Leader — and What It Means

In thirty years China has gone from an economic basket case, recovering from one of the worst famines, to the second largest economy. Many in the West have little imagination about the next thirty years. Western political systems do not match China’s effective long-term planning.

Australia, with short electoral cycles and belief in market economics, shows little sign of long-term strategy. We will prosper by selling minerals and agricultural produce to China — but that is because it suits China. The Chinese Government is astute: it survives by satisfying Chinese needs, not Australian needs. That is our job.

The American system seems hostage to conglomeration and globalization. Massive global conglomerates can operate beyond law or use clout to shape laws. Europe has bogged itself down in ineffective bureaucracy. This leaves the door open for China to become the dominating economic power.

China — The Downside: Environment and Food

The negative side is environmental impact. Beijing’s air pollution is notorious, but the whole country is under threat from industrialization. China’s mountain ranges make it naturally beautiful, and it seems to be holding the battle in key regions, but there is a more immediate battle: food production.

When I sold my company I decided to spend my remaining time and energies on soil and water and the outcome — food production. In China we have far from a pretty sight.

Chinese Farming — Tradition Under Pressure

China has an agricultural system thousands of years old that would make many a permaculturist green with envy. But mass migration of the young and fit to cities creates a gaping hole, and China appears to be adopting some of the worst practices of Western agriculture, with damaging results.

This is not the full truth. There are areas like the Loess Plateau where traditional peasant farming caused major damage that has been reversed by enlightened soil conservation. Traditional farming is not automatically sustainable — I learned this in Ethiopia where poverty forced people to destroy trees and burn manure just to survive.

Markets, Chemicals, and “Does My Organic Come Second?”

Walk through Chinese markets and you might think talk of destructive farming is nonsense: vegetables are abundant and very fresh, often picked near mega-cities and delivered the same morning. This seems superior to Australia where food is picked early, shipped long distances, stored, then stored again in fridges.

Comparing Chinese produce to my home grown vegetables can make Chinese farming look better. I fight pests without toxic chemicals to protect soil biology, but cane toads, beneficial insects and companion planting are no match for toxic chemicals — at least in the short term based on initial appearance.

Even greater concern is what seems like excessive use of acidic nitrogen fertilisers creating hard crusty soils (even if you can call them soils). The Chinese might politely say this is none of my business — except for one reason: world food production.

World Food Production — Why China Matters Globally

My work on wicking beds began in Africa, trying to provide sustenance food in drought. I read we currently produce enough calories to feed double the world population, though this ignores micronutrients like vitamins, minerals and phytochemicals. The dominant cause of malnutrition is political instability and war. Number two is acquisition of prime land in developing countries for export crops like coffee and cocoa, often by multinationals.

China’s impact on manufacturing is obvious; its impact on food security may be equally significant. With 1.4 billion people, China will look to other countries to secure food supply. Its activities in Africa, South America and Australia should be no surprise, and its efforts to protect its own food supply will affect the global food supply.

It’s Not How Much Food — It’s What Is in It

China now has the largest population of diabetic sufferers. Obesity and diabetes are not just Western problems — they are global and linked to the food system. We have a surplus of energy components (fats, sugars, carbohydrates), and enough energy food to feed the world twice over. The “Armageddon press” warnings about shortages are often simplistic.

The real fear may be the lack of balance between energy and micronutrients — vitamins, minerals and phytochemicals. The challenge for future food is not quantity but producing food with the right nutrient balance in a sustainable way.

Humans Can Compensate — So What Are the Chinese Doing Right?

The debate often misses the body’s capacity to correct for a poor diet. There are tribes living on almost exclusively meat or fish who, in theory, should be unhealthy — yet appear fit. Many trace elements and phytochemicals are harmful in bulk, so why aren’t people dropping dead everywhere? Perhaps the body has elaborate systems to compensate — if it is allowed to.

Look at diabetes in China: a decade ago it was rare; now one in ten are suffering — a major disaster. But look differently: nine out of ten Chinese are fit and healthy with beautiful bodies (I have studied — in the name of science of course). So what are they doing right?

Could it relate to the bulk toilet paper purchases? I am stunned by how much food Chinese people can eat. At restaurants, course after course arrives: fish, beef, chicken, pork, multiple vegetable dishes, and unknown things I eat without looking. This huge pile of food — including the so called bad fats and carbohydrates — just disappears, yet the people around the table are typically not obese. So why?

Conclusion — Questions for the Next Newsletter

China is mind boggling: if you think you understand it you are probably wrong, and it will change in six months anyway. Food is equally mind boggling. At a personal level we face conflicting expert opinions that often miss the importance of soil. At a global level we have a food industry controlled by large corporations, overproducing food widely condemned as unhealthy while slowly destroying soil nutrient value.

Will I gain more insights during my next month in China? Will I find, despite my skepticism, a super-plant that lets people eat as much as they like of whatever they like? Will I find out how the majority remain fit, slim and healthy despite diets experts would condemn? Will I find clues to an agricultural system that feeds the world with healthy food without destroying soils?

Will I be able to de-boggle my mind to present effective answers in my next newsletter?

All I know for sure is that life is never dull in China.

Gin Gin State School Wicking Bed Project: Educational Gardening for Schools

This community project at Gin Gin State School in Queensland brought teachers, students, parents and local volunteers together to build outdoor wicking beds. Supported by Waterright wicking bed technologies, the project created productive garden beds that conserve water and improve soil fertility. It served as a pilot for schools and community groups interested in sustainable gardening, hands‑on learning and growing food more efficiently using wicking bed methods and local collaboration.


Introduction

On Sunday, 11 February 2007, the Gin Gin State School community in Queensland gathered for a working bee to create a wicking bed garden at the school. Teachers, parents, students and people from the wider Gin Gin community volunteered their time to build beds that would serve as a practical example of water‑efficient gardening and sustainable food production. The project aimed to demonstrate how wicking bed technology could be implemented in community and educational settings.

The Wicking Bed Project

The Gin Gin State School Wicking Bed Project was set up using Greg Colin Austin’s wicking bed technology — a method that combines water storage, soil biology and efficient irrigation. These beds were intended as a working pilot that could be replicated by other schools or community groups. Wicking beds have also been used in other Waterright initiatives and incorporated into systems like the EasyGrow system, which provides additional planning resources for efficient garden design.

Community Collaboration and Participation

The success of the project lay in the community’s enthusiastic participation. Volunteers worked together throughout the day, undertaking tasks such as preparing materials, building the bed frames, installing linings, preparing soil mixes and applying mulch. The communal nature of the project highlighted how shared efforts can empower schools and neighbourhoods to develop sustainable infrastructure that doubles as an outdoor classroom.

Local involvement also offered students a chance to learn about gardening, water conservation, soil health, and teamwork. Engaging parents, teachers and community members reinforced the idea that sustainability and practical skills can be learned and taught through active participation rather than theory alone.

Construction of the Beds

Building the wicking beds involved several key steps. Volunteers began by measuring and cutting sleepers for the bed frames. Steel bolts were prepared and drilled to secure the frames. Once the basic structure was assembled, waterproof poly sheets were laid inside the beds to create an underground reservoir that would hold water and encourage upward movement to plant roots — the essence of the wicking system.

Soil preparation was an important stage. A mix of soil components was used — including worm castings supplied by Kookaburra Worm Farms, garden soil and sugar mill mud. These organic materials helped create a fertile medium that supports strong plant growth and soil biology working in harmony with the wicking action. Wheelbarrows were queued up to move soil from mixing areas into the prepared beds, demonstrating the communal effort involved.

Mulching and Final Preparation

After the soil was in place, volunteers spread straw mulch across the surface of the beds. Mulch serves several valuable functions: it helps retain soil moisture, suppresses weeds, and gradually breaks down to enrich the soil further. Mulching also gives the wicking beds a finished, tidy appearance suitable for an active school environment.

With the beds completed, members of the community helped tidy up the area and celebrate the achievement. The project not only provided functional garden beds but also offered students and parents a chance to reflect on the importance of water‑wise gardening and how hands‑on initiatives can bring an entire community together for a shared purpose.

Educational and Community Impact

Beyond the practical benefits of efficient vegetable production and soil conservation, the wicking bed project had a broader educational purpose. School gardens are powerful tools for experiential learning — helping children connect concepts like water cycles, plant biology, food production and environmental stewardship with real‑world applications. In a wicking bed, students can observe how water moves through soil, how roots grow toward moisture, and how organic matter and soil biology enrich plant growth.

Projects like this also strengthen community ties. By involving parents and local volunteers, schools become hubs of collaboration where learning extends beyond the classroom into shared outdoor spaces. Community members bring a range of skills and perspectives, contributing to a richer learning environment.

Why Wicking Beds Matter

Wicking beds are particularly suitable for schools and community gardens for several reasons. They use water more efficiently than traditional surface irrigation, reducing waste through evaporation or runoff. Water stored in an underground reservoir moves upward by capillary action directly into the root zone, providing plants with consistent moisture that encourages healthy growth with less frequent watering — an ideal feature in areas prone to dry conditions or water restrictions.

The technology also demonstrates principles that students can apply at home or in community spaces, including composting, soil improvement, water harvesting and sustainable food production. These lessons align with broader environmental education goals by showing how simple technologies can make a lasting impact on resource conservation and food security.

Lessons Learned and Ongoing Use

Since its completion, the Gin Gin State School wicking beds have continued to serve as a demonstration of sustainable gardening. Even years later, the beds remain functioning and contributing to school gardening activities. Their continued use reinforces the value of practical, hands‑on projects in education and community engagement. By maintaining the beds, students learn about responsibility, seasonal cycles, and the long‑term care of living systems.

Interest in this project has inspired similar initiatives elsewhere, proving that simple, locally built sustainable systems can be effective and replicable when communities invest time and effort. Schools, community groups and gardening clubs can use projects like this to promote water‑wise gardening practices and foster environmental stewardship across generations.

Conclusion

The Gin Gin State School Wicking Bed Project stands as a testament to what a committed community can achieve. By embracing simple, effective wicking bed technology, the school created a sustainable garden that conserves water, enriches soil, and supports student learning. The project demonstrates how hands‑on involvement in sustainable technologies can unite communities and empower learners of all ages to engage with environmental challenges and solutions.

The Future of Agriculture: Adapting Farming to Climate Change

This article is based on a talk Colin Austin — inventor of the wicking bed — gave during a China tour in September 2009. Climate change, shifting rainfall, and rising evaporation are reshaping how we grow food. It highlights practical, low-tech, and biological solutions: wicking beds, soil regeneration, micro-hydrology, and local water harvesting. Combining resilient soil biology with targeted water capture and efficient irrigation helps communities protect food production, restore land, and make agriculture more reliable in a hotter, drier climate.


Introduction

My aim is to share practical approaches that respond to the twin pressures of climate change and water shortages. China and Australia share many challenges: large land areas, regions of low rainfall and dependence on river systems that originate in distant mountains. Recent droughts in both countries show how fragile food systems can be when water becomes scarce.

I will describe a horticultural system that has performed well in dry, variable climates: the wicking bed. I will also examine the broader issues that threaten future food production — climate shift, competition for water, degraded soils and pathogens — and show how micro-biology and micro-hydrology can form the core of a resilient response. Finally, I’ll outline practical steps we can take at farm and community scales to safeguard food supply.


Part 1 — Overview of Wicking Beds

Wicking beds are a horticultural system that combines micro-hydrology and micro-biology to produce exceptional plant growth while using minimal water, nutrients and labour. The basic design includes an underground reservoir that holds water and acts as a decomposition zone. Capillary action wicks moisture up into the root zone where soil stays moist without becoming saturated. There is no loss of water beyond the root zone and very little evaporation from the surface.

For maximum benefit the root zone soil must be nutrient rich and well structured. Special worm breeds and active microbial communities convert organic residues into readily available nutrients and, at the same time, create a porous, aggregated soil structure. The result: a layer in the soil with the ideal balance of air and water for continuous plant growth.

Wicking beds can be small boxes for research and household gardening, semi-raised beds for heavier soils, or larger in-ground installations for production. They can be fed by existing irrigation or by local water harvesting systems. The system concentrates scarce water into small, highly productive areas — a key strategy when water is limited.


Part 2 — Fears about Future Food Production

Climate shift

Climate change shifts traditional climate zones. Areas that once received reliable winter rain may find the rainfall pattern has moved. In southern Australia, for example, winter rains that once fell inland are now more likely to fall further south, often over the ocean. Rivers that depend on mountain snowmelt are threatened by reduced snowfall and earlier melt, removing a natural seasonal water store that farmers have relied on.

Competition for water

Population growth and urban expansion increase demand for high quality water, often redirecting supplies away from irrigation. Agriculture competes with cities and industry for the same limited resource. At the same time, runoff of agricultural chemicals creates conflicts between urban and rural water uses. These pressures make efficient on-farm water use more urgent.

How real is the threat of food shortages?

Global food production has increased in many regions, thanks to better genetics and farming methods. But these gains often depend on higher inputs of water and fertiliser. Where water supply limits these inputs, productivity cannot expand. In many places the problem is not absolute crop production but distribution and access: poverty, politics and infrastructure failures often cause hunger even when global supplies are adequate. Still, climate change threatens to limit the effectiveness of current high-input systems unless we build resilience.

The role of soil

Modern intensive farming often treats soil as merely a physical support for crops, with nutrients supplied externally. While this can be productive short term, it externalises ecological functions and weakens soil microbial life. Long-term resilience requires soils that host active microbial and fungal communities capable of cycling nutrients and supporting plant health.

Pathogens and disease

Highly sanitized, input-heavy systems can invite new disease problems. Removing biological complexity often allows opportunistic pathogens to dominate; many microorganisms rapidly evolve resistance to chemical controls. Restoring soil biology helps keep pathogens in balance and reduces reliance on chemical inputs.

Pioneering species and competition

Microbial communities behave much like plant communities: pioneer organisms colonise disturbed environments rapidly and are later outcompeted by slower-growing, beneficial microbes. Managing soil to favour beneficial communities is therefore essential for long-term health.

Living soil

Increasing soil carbon and fostering a living microbiome can dramatically improve soil function. While short-term gains from chemical fertilisers can seem economically attractive, the sustainable path is to rebuild biological fertility so soils retain water, resist erosion and support nutrient-dense crops.

Climate change in Australia

Australia’s southern agricultural belt has seen shifting rainfall and reduced snowmelt in upstream catchments. This forces a rethink of where and how we grow crops. Some areas may need to be retired from intensive agriculture, while others could be developed with appropriate, climate-adapted methods.

Local water harvesting schemes

Because large river systems are fully allocated, local water harvesting becomes important. Small dams, recharge pits and ephemeral creek capture can soak water into the ground to recharge local water tables. These stored subsurface waters can be pumped later, often yielding more usable water than would appear from surface capacity alone.

Targets for Australia

Key priorities are protecting traditional production areas, opening new regions as climate belts shift, and accepting that some marginal lands must be retired. Combining local harvesting, efficient irrigation and soil regeneration can protect food supplies even as climates change.


Part 3 — The Importance of Microbiology

Land degradation

Past decades of erosion and intensive tillage have shown how easily topsoil can be lost. Rehabilitation requires restoring soil structure, organic matter and microbial life. Early experiments showed that simple, single-variable fixes rarely work; regeneration depends on combinations of practices tailored to local conditions.

Soil regeneration

My experiments showed that areas with moderate, uniform moisture and active microbiology regenerated fastest. Moisture is necessary but not sufficient — microbes and worms must be supported with food (organic matter) and appropriate moisture regimes so decomposition and nutrient cycling proceed efficiently.

No single solution — use a combination of methods

Soil regeneration is complex. Successful restoration typically combines compost, green manures, crop rotation, reduced tillage and targeted water management. Mathematical optimisation rarely replaces hands-on adaptation to local variabilities.

Water plays a crucial role

Even apparently uniform paddocks have complex underground flow paths. Where moisture is moderately and consistently maintained, microbial activity and plant growth recover. Where soils dry excessively or remain waterlogged, regeneration lags. Managing subsoil moisture is therefore central.

Microbiology regenerates soil

Worms and microbes are the primary agents of regeneration. Worms cannot process raw plant matter without microbial pre-processing; microbes must be supplied with energy (organic matter) and maintained at suitable moisture and temperature ranges. Creating those conditions accelerates soil formation and carbon sequestration.


Part 4 — Micro Hydrology

Sturt and Simpson deserts

Deserts show how local hydrology can determine vegetation. The Sturt Desert has hard flat soils that shed rain and favour evaporation; it supports little vegetation. The Simpson Desert, with dunes and clay pans, can capture and route water into underground sinks, producing brief but intense greening after storms and supporting deeper-rooted plants.

Importance of micro hydrology

The lesson is that local landform and subsurface structure amplify water into concentrated zones where plants can access and store it. For agriculture we can imitate these processes: create percolation holes, capture water in underground stores and amplify scarce rainfall into productive beds.

Percolation holes

When deep roots die, they leave channels that allow deeper infiltration — natural percolation holes. In managed systems we can create or preserve such channels and design landscapes to move water underground where it is less prone to evaporation.

Water amplification

Concentrating water into smaller, well-managed areas produces far greater growth than attempting to wet large areas poorly. Desert plants and human systems alike benefit when water is amplified into productive zones.


Part 5 — Sources of Water

Where large rivers are exhausted, rain harvesting and groundwater recharge become critical. In landscapes with high evaporation, shallow dams that allow percolation into the soil — rather than sealed reservoirs — can replenish local water tables and store water in subsurface reservoirs. Planting trees and maintaining vegetative cover recycles moisture locally, increasing humidity and the probability of rain. Sewage and organic waste can also be treated and used as a nutrient-rich water source if managed safely.


Part 6 — The Wicking Bed Technology

Background to the wicking bed system

The wicking bed concept began as a cheap, easy way to store water for critical crop stages in erratic rainfall zones. A subsurface reservoir supplies nutrient-rich water to the root zone via capillary action. The topsoil remains dry at the surface, reducing evaporation, while a moist layer at rooting depth supplies conditions ideal for microbes and roots.

A new horticultural system

Wicking beds are not simply an irrigation trick: they form the basis of a horticultural system where some land is devoted to highly productive wicking beds while other land is used to harvest water and deeper nutrients. Deep-rooting plants grown on non-irrigated land extract nutrients and return them via biomass into the wicking system, creating a cyclical nutrient flow.

Applications

Wicking beds are flexible. Small boxes are useful for research and household food production. Semi-raised beds work well in heavy clays and high summer rainfall zones. Above-ground beds suit community groups without earth-moving equipment. Wicking beds can be adapted for trees using raised or ringed reservoirs and for row crops using narrow subsurface reservoirs that move laterally to serve multiple plants.


Part 7 — Carbon Capture

Plants extract carbon from the atmosphere but return much of it quickly through decay. If organic material decomposes in dark, humid, subsurface conditions it is processed by fungi and worms into forms that remain in the soil for many years. Wicking beds can accelerate this process: biodegradable material is incorporated and decomposed underwater in a controlled manner, then wicks up as nutrient-rich solution to feed plants while locking carbon in soil aggregates.

Sustainable soils with high organic matter also store significant carbon. Paying farmers for verified soil carbon sequestration — ideally through practical, process-based monitoring — would create economic incentives to adopt regenerative practices. This would support farmers financially, improve soil fertility and help offset greenhouse gas emissions.


Practical Steps and Final Thoughts

Practical actions include: protect and restore soil organic matter; adopt subsurface and water-efficient irrigation such as wicking beds; create local water harvesting infrastructure that recharges groundwater; plant deep-rooted trees on non-irrigated land to mine and recycle nutrients; encourage community composting and safe reuse of organic wastes; and explore carbon incentive schemes tied to regenerative practices.

No single technology is a silver bullet. The future of agriculture will be found by combining genetic advances with careful water management, living soils and community cooperation. If we focus on the fundamentals — water and biology — we can adapt food systems to a hotter, drier world and support resilient, nutrient-rich production for generations to come.

This article introduces the Healthy Food Association, a non-profit community focused on improving health through nutrient-rich, biologically active soil and home-grown food. It explains how members can share experiences, gain support, and learn about sustainable growing techniques like wicking beds. The Association emphasizes education, collaboration, and voluntary participation, providing guidance on food production without commercial influence, while encouraging healthy, informed choices in gardening and nutrition.


Introduction

The Healthy Food Association is a community of people who share the belief that growing and eating food from nutrient-rich, biologically active soil can improve health. The association provides information and education on producing healthy food, with particular emphasis on methods such as wicking beds, which allow plants to access water efficiently and support soil biology.

Purpose and Structure

The Association is non-commercial and non-profit. Its main goal is to facilitate knowledge exchange among people interested in healthy food production. Members can share experiences, submit articles, and ask questions, which are then published online or in newsletters. Participation is voluntary, and all contributions are intended to support learning and collaboration rather than profit.

Communication and Resources

A dedicated website, currently under development, will act as a central hub for articles, discussion, and information exchange. Members can submit content via email to be reviewed and potentially shared with the wider community. There is no fixed publication schedule, allowing flexibility in sharing timely advice and practical insights.

Coordination and Volunteers

Colin Austin currently coordinates the Association on a voluntary basis, maintaining operations and website management. Additional principals assist in running activities, responding to questions, and providing guidance to members. All efforts are unpaid, emphasizing the community-driven nature of the Association.

Membership and Participation

Anyone interested can join the mailing list by contacting the Association via email. Members can receive newsletters, submit questions, and contribute articles. There is also a separate mailing list of volunteer coaches who help members set up and maintain wicking beds, providing practical, hands-on guidance.

Role of Coaches

Coaches operate independently of the Association and may charge for services or products, but any financial arrangement is between the coach and the client, not the Association. The Association simply facilitates communication and information sharing, ensuring members can access guidance without any commercial obligation.

Principals and Contact

The Association currently has four principals who provide expertise and oversight. They are contactable through the main email address, and questions from members may be circulated to appropriate coaches for responses. All advice is offered in good faith based on current knowledge but without legal or financial responsibility.

Guiding Principles

The Healthy Food Association is not a legal or trading entity. It has no bank account or financial status. It functions purely as a community of like-minded individuals aiming to improve health through better food growing practices. Members are encouraged to participate voluntarily, share knowledge openly, and support each other in creating nutrient-rich food systems.

Conclusion

The Healthy Food Association exemplifies a collaborative, non-commercial approach to improving health through sustainable food practices. By sharing experiences, supporting soil biology, and promoting home-grown produce, the Association helps members make informed, practical choices. This focus on education, cooperation, and voluntary engagement fosters a community where healthy food production and learning go hand-in-hand.

Intelligent Control

Intelligent Control

Why is it that we are in the midst of a health crisis? What I call the fat in the wrong places epidemic of diabetes, dementia, obesity with their associated side effects yet there seems so little public reaction.


These are man made diseases caused by corruption of our intelligent control system which has evolved over millions of years into a highly sophisticated system which manages how much and where we store our fats.

But we are now starving and poisoning our gut brain, which forms an essential part of this intelligent control system. The facts are clear – but where is the social action as we have with climate change, plastic litter, animal rights etc which whatever your views have certainly created social action.

Surely, as a compassionate and cooperative species, we should ensure everyone has access to a diet that makes them healthy.

The health of the people should take priority over corporate profits.

Yet diabetics, on the road to becoming a blind cripple, obese people heading for an early death from heart attack – compliantly take their pills as though there were no alternative when there clearly is – in the food we eat. Why?

One explanation is that we are all so different, some people are totally immune to these disease and will never get fat or diabetic whatever they eat or do. Others will become diabetic even with the best possible diet.

But what we have done, with our food and toxins, is to shift the distribution so whereas fifty years ago there was just a very small minority of people suffering – now the bulk of the population has been pushed into the at risk zone.

Being at risk of becoming a blind cripple and dying young from heart disease does not seem to be adequate motivation for people to want action, and by the time people are in the waiting room to have their legs chopped off it is too late.

The pills and potions used to treat these diseases only treat the symptoms, we need to treat the root cause – corruption of our intelligent control system.

Medical Advances

Medical science has made great strides in identifying the key hormones, like ghrelin and leptin, which our bodies use as part of our intelligent control system, but these are just the messengers. We still has to unravel the complex logic which actually takes the decisions.

We can study evolution to get some indication of this decision making process. We can see that for millions of years our predecessors ate wild plants to feed our gut biology, and we can study the computer science of artificial intelligence to gain an impression of how it may work.

But we can be sure from the millions of years of our evolution, until the last few decades, that our intelligent control system was highly effective in managing our bodies.

We can be equally sure that a diet which included wild plants played a key role. The change in the our diets over the last few decades is a key factor in the failure of our intelligent control system and the consequent health epidemic.

But we cannot feed a population of 7.8 billion people on wild plants. But we can study ecology to understand how the balance of plants (and animals) worked together as an effective and sustainable system.

This has led to the development of the Gbiota™ bed which aims to restore our gut biology.

So Where Does That Leave Us?

Home gardeners, by themselves, are not going to create a healthy society. We need to establish an alternative food system to supply Gbiota produce to the wider society.

This will probably start with tree changers who see an opportunity to help improve the society in which we live, and earn honest money, by providing Gbiota produce to those who cannot be self sufficient.

Hopefully this will then spread to the enlightened regenerative farmers who see the damage being done to our soils by industrial chemical farming.

This website make no effort to be populist and is targeted to the people who are prepared to put the effort into understanding how they can protect their intelligent control system and are prepared to take the action needed to protect their food supply.

How Life Works

How Life Works

The Two Great Synergies

Life is powered by the sun. Plants use sunlight to combine carbon from the air and hydrogen from water to create carbohydrates — stored energy. This is the foundation of the food chain.

Plants also release sugars from their roots to attract soil microbiology. This microbiology gathers water, minerals and complex compounds from the soil and delivers them back to the plant. This is the first great synergy: plants and soil biology work together.

When we eat plants — or animals that eat plants — we absorb this energy, these minerals, and some of the associated microbiology. Inside us, the gut microbiome helps us digest food and replace body cells. This is the second great synergy: creatures depend on internal microbiology to stay alive.

We do not live alone — we live in partnership with soil biology and gut biology. Without them, we cannot digest food, regulate sugar, or repair our bodies.

We need sugars for energy, but only in balanced amounts. Too little and we tire. Too much and tissues begin to fail. This imbalance is central to diabetes — rare historically, common today — because many people no longer feed the gut microbiome that regulates sugar metabolism.

How We Drifted From Our Evolutionary Base

The trillions of gut microbes that help regulate appetite, repair tissues and support immunity have short lifespans. They must be continuously replenished by eating biologically active food. We need only a small amount — but it is essential.

In the past, nutrient-rich, biologically active soil provided this naturally. Meanwhile, energy-rich foods (fats and sugars) were rare, so we evolved to crave them. Today, the situation is reversed: energy foods are cheap, abundant and heavily marketed, while gut-supporting foods are scarce and undervalued.

Our bodies are not craving “more food” — they are craving missing minerals and gut biology. But we respond by overeating the wrong food.

Profit vs Responsibility in the Modern Food System

The modern food industry has done what it was designed to do: increase production and profit by supplying the foods people crave. In the last eighty years, energy food production has risen by 4.5× while population has risen only 3×. This is a technical success.

However, this food is incomplete. It provides fuel but not the biology and trace minerals required for real health. Marketing has convinced consumers that this is “complete food,” which has contributed to chronic disease, obesity and metabolic dysfunction.

When the product is life-critical, “just following profit incentives” is not enough. Food shapes the health of a civilisation.

The Earth will continue circling the sun for billions of years. The question is whether humans will remain healthy enough to thrive here.

Human health depends on gut biology, which depends on soil biology. Industrial farming has damaged soil microbiology at a global scale. The consequences are already visible in chronic disease and increased vulnerability to infectious illness.

This is not a story of doom. It is a call to act intelligently, guided by empathy and responsibility toward future generations.

The Science Underlying Gbiota Beds

  • Our gut microbiome regulates appetite, tissue repair and immunity.
  • Gut biology originates from soil biology and continues to adapt based on what we eat.
  • Different plants cultivate different soil microbes; a varied diet builds a diverse gut microbiome.
  • Traditional soils contained abundant biology and trace minerals; modern industrial soils do not.
  • Increasing energy food while decreasing biological food has led to widespread metabolic disease.

The Purpose of Gbiota

Gbiota beds regenerate soil biology rapidly enough to support the current human population. The aim is not simply growing vegetables, but restoring the biological foundation that allows humans to remain healthy.

The practical model is a network of local micro-farms supplying communities directly — balanced, decentralised, resilient.

Three Functions of Food

Three Functions of Food

We often classify food by nutrients — carbohydrates, fats, proteins — but it is more useful to understand what food actually does in the body. Food has three core functions:

1. Energy Food

Energy food includes carbohydrates, fats and proteins. If it contains carbon and hydrogen, the body can burn it for fuel, releasing carbon dioxide and water. This is the basic energy supply that keeps us moving, thinking and alive.

2. Food to Rebuild the Body

Our cells are constantly wearing out and being replaced. To rebuild our tissues we need access to a wide range of minerals and complex biological compounds. Some of these can be manufactured by the gut microbiome if the right minerals are present. Others, such as Vitamin B12, must come from diet.

3. Food for the Intelligent Control System (Gut Brain)

The body is not a collection of organs acting independently. It is regulated by an intelligent control system — homeostasis — that constantly senses, interprets and adjusts how the body functions. A large part of this control system is made from the trillions of microbes in the gut.

We don’t get fat simply because we eat too much — our gut-based control system tells us to store fat, and then drives appetite to make that happen.

These gut microbes are short-lived and constantly renewing. They require small but steady amounts of food that feeds them — fibre, trace minerals and plant compounds. This is what we refer to as gut brain food.


Why We Need to Feed the Gut Brain

The gut microbiome contains trillions of cells from thousands of species, communicating both amongst themselves and with the brain. This combined system regulates appetite, energy levels, tissue repair and immune function.

The Gbiota project focuses on growing food in biologically active soil, supplying natural prebiotics and probiotics. People can either grow their own in Gbiota beds or join local groups to buy from regenerative growers.

Gut Health Concept Plant Based Foods

What the Gut Brain Regulates

  • Appetite and energy balance
  • The chemical building blocks needed to replace aging tissues
  • A large part of the immune system

Our gut biology evolved in the soil. Healthy soil leads to healthy gut biology. Healthy gut biology leads to healthy bodies.


Soil Biology

Soil is created by microbes breaking down rock and organic matter. This is a living process involving bacteria, fungi, and worms. Modern chemical agriculture has replaced this process with fertilisers and simplified soils, producing high yields but stripping away beneficial biology.

Many agricultural chemicals may not harm us directly, but they do harm the soil biology we depend on.

Trace Minerals

Early soils contained a broad range of minerals. Plants only require some of these, but humans require many more. Industrial agriculture replaces only nitrogen, phosphorus and potassium, not the trace minerals essential for our hormonal balance, cell function and metabolism.

Modern Industrial Farming

Industrial farming has created a food system that supplies energy food cheaply and reliably, but not gut-supportive nutrients. The gut senses this deficiency and triggers hunger, causing people to overeat in an attempt to obtain missing minerals and biology. This has contributed to global epidemics of obesity, diabetes and related chronic diseases.


How We Evolved to Seek Food

For most of human history, energy-rich foods were scarce, while mineral-rich, biologically active plants were abundant. Our biology therefore evolved to crave energy food. The modern food industry takes advantage of this — supplying energy food cheaply and profitably — while the foods that feed the gut brain are harder to find.

The result is a mismatch between what we crave and what we actually need.

Changing the Food System

To restore balance, we must increase access to food that feeds the gut microbiome. This requires soil with active biology and a full spectrum of trace minerals, which can be achieved by recycling organic waste and rebuilding soil health.

Food and Innovation: How Modern Agriculture Changed Our Health

Food and Innovation: How Modern Agriculture Changed Our Health

 


Innovation is often associated with digital technology — phones, electric cars, and automation. But one of the largest shifts has been in how we grow food. Over the past eighty years, industrial agriculture has introduced fertilizers, large-scale irrigation, pesticides, hybrid seeds and mechanization. This has increased food production more than fourfold.

We now produce more than enough calories to feed the global population. Yet, at the same time, rates of diabetes, obesity and chronic inflammation have accelerated. The reason is simple: the food system now produces energy food, but not food that nourishes the gut microbiome, the biological system that regulates appetite, immunity, metabolism and mood.

The Real Cost of Industrial Agriculture

Industrial farming excels at producing carbohydrates but does not support the microbes that live in the gut. These microbes form a genuine regulatory network — often called the gut brain — which influences hunger signals, energy use and immune function.

We are producing more calories than ever, but fewer of the nutrients that maintain gut health and internal regulation.

This lack of microbial support is a major factor in the rise of metabolic disorders. The issue is not simply what we eat, but the biological state of the soil that food is grown in.

Why Innovation Must Change Direction

The traditional approach to innovation is to patent an idea, secure monopoly rights, and use marketing to shape consumer behaviour. This may be profitable, but it does not always serve public wellbeing. When food systems do not support gut health, society pays the cost through disease, lost vitality and increased medical dependence.

Not all innovations should be commercialised purely for profit. Some determine the conditions for long-term health and survival.

The Gbiota approach focuses on restoring biologically active soil so plants naturally develop the fibres, minerals and beneficial microbes that act as prebiotics and probiotics. This is not a supplement, a diet trend, or a health fad — it is a return to how food supported human biology for most of our evolution.

The Anthropocene and the Food System

Human impact has now reached the point where we can change the stability of the planet itself. Soil degradation, aquifer depletion, loss of biodiversity and climate instability are all linked to how we grow food.

We are no longer passive inhabitants of nature. We are shaping the system we depend on.

We are the first species with the power to destroy the systems we rely on — and the last with the power to restore them.

Technology, Convenience and Control

Modern convenience allows food delivery at the tap of a screen — but disconnects us from the source of our nourishment. When we no longer know who grows our food, how it is grown, or what is in the soil that feeds it, we lose agency over our health.

The solution is not to reject innovation, but to use it responsibly — to rebuild living soil, restore gut biology, and support community-based food production systems.

The Principle of Gbiota Beds

The Principle of Gbiota Beds

The aim of the Gbiota system is to restore and maintain a healthy gut by growing plants that act as natural pre- and probiotics. If we eat mainly modern processed foods, our gut becomes populated by sugar-loving microbes that drive cravings for more sugary food. The good news is that gut biology can be changed simply by changing what we eat.

In a Gbiota bed, beneficial biology is bred in organic waste under carefully controlled moisture conditions.

How a Gbiota Bed Works

The lower half of the bed is filled with organic waste. The upper layer, where plant roots grow, contains living soil. Water is pumped through a filter mixture of compost, manure, and minerals, forming a nutrient-rich “compost tea.”

A temporary soil dam allows this tea to pool through the bed, feeding the root zone. When the pump switches off, water drains back out of the bed, pulling fresh air into the soil. This cycle accelerates the natural formation of biologically active, nutrient-rich soil.

Healthy soil is not just dirt — it is a living system that feeds the gut biology that in turn regulates our bodies.

Aims of the Gbiota Project

Everyone in an affluent society should have access to affordable, gut-supportive food. The trillions of microbes in our intestines do far more than digest food — they act as an intelligent regulating system for appetite, energy, immune function, and emotional balance.

This “gut brain” helps us eat enough — but not too much. When it is functioning well, it supports stable energy and healthy weight. When it is disrupted, we see the familiar modern pattern of sugar cravings, obesity, diabetes, and inflammation.

We did not create the modern epidemics by accident — we changed how we grow and eat food.

The Shift to Industrial Agriculture

For most of human history, soil naturally contained the microbes and minerals needed to nourish our gut biology. Around eighty years ago, large-scale chemical agriculture began to replace traditional soil-building processes.

Industrial agriculture has been effective at producing “energy food” — the carbohydrates that keep us alive — and global food production now exceeds the needs of the population. But this has come at a cost: the depletion of soil biology and minerals essential to feeding our gut microbiome.

Without living soil, we cannot maintain a healthy gut. Without a healthy gut, our biological regulation breaks down. Without that regulation, we see the diseases of modern abundance.

We may still manage to produce energy food, but as soil degrades, we lose the food that feeds our gut intelligence — and we cannot survive without it.

Restoring Healthy Soil, Quickly

The Gbiota system is a practical way to recycle food and organic waste, add manures and essential minerals, introduce beneficial microbes and worms, and maintain the moisture levels needed for microbial activity.

Instead of waiting decades for healthy soil to form naturally, it can be created in months. Any competent grower — home or commercial — can build and manage a Gbiota bed.

Restoring gut health is not about exotic supplements or miracle diets. It is about restoring the living relationship between soil, plant, and gut.

Gbiota Beds in Practice

Gbiota beds are already in use by home gardeners. The method is documented and continually improving. They offer a reliable way to grow food that directly supports gut biology — real pre- and probiotics grown in living soil.

This is not just gardening. It is rebuilding the foundation of health.
