Mindfulness can be the answer to many of the problems each one of us faces every day.
So what is mindfulness? Mindfulness is the practice of living in the here and now.
Simple. For example, how often when you are washing your dishes are you thinking about something else? When you are washing dishes, you should be thinking just about washing dishes. When you are shopping for food, are you hungry and thinking about what you want to eat? Supermarkets like this, because you end up buying a lot of things you really don’t need.
By living in the present moment, and paying attention to the thoughts that float through our brain, you become more in control of your life. You can think about whether your actions and proposed purchases are sustainable, and do not use planetary scarce resources.
It takes practice to do this and a couple of daily meditation sessions are extremely beneficial to our health and controlling our feelings and desires. It is very important to be mindful because to think about sustainability takes a lot of effort to overcome old, ingrained habits. It is important to constantly ask yourself if this decision is going to have the least impact on the planet.
As you practice, and constantly remind yourself to be in the moment, you will gradually increase your freedom and your life will become more sustainable.
The dictionary provides lots of different definitions of this term. The meaning I am going to adopt is ” to supply with food and drink, or the necessities of life, as persons”. While this doesn’t match the meaning adopted by other authorities such as the United Nations, I think it defines my approach to sustainable living better.
While many businesses and organisations debate sustainability and how to define it, and the definition of “triple bottom line”, I am getting on with my approach to being sustainable living in providing food, shelter and energy to meet my life’s requirements.
Beyond the basic necessities (food, clothing and shelter) for sustaining our physical life, how much money and other possessions do we really need? These questions are often not investigated and pondered upon, but we spend our lives trading our time and skills for money. A life that is free and meaningful does not need the latest fashion or gadgets or expensive overseas holidays or the latest model car. Working long hours really doesn’t allow the time we need to look after our spiritual needs and for time to spend with family and friends – the things that make for an enjoyable life. Being rich is a state of mind, not a bank balance figure.
I’m not saying that money is not important – it is, up to a certain level. Once our basic needs are met, pursuing more money distracts us from the important things in life. It’s easy to become entangled in a consumerist society, and to think that consumerism provides freedom. Consumerism is destroying the very planet that we live on. Everything we consume is provided by our planet, and ultimately is returned back to it. Climate change and disappearing ecosystems are the indicators of our over consumption. How much longer can we persist with our consuming patterns before we go beyond the point of no return? Some scientists already think that we have gone beyond the tipping point with our production of carbon dioxide induced climate change. We need to remember past climatic climaxes that mean that all humans have come from an estimated 600 breeding pairs of homo sapiens. Is this going to happen again?
So what can we do? Are there alternatives? Much research is occurring in this area. Already research has shown that we are past peak oil production, but we are still not embracing renewable energy sources at the rate we should be. We are also at or past peak water consumption, with many countries populations experiencing water stress i.e. less water than they require each day to maintain a healthy life.
I think that we all have a responsibility to minimise our use of resources. Sure, I still have a phone, TV and many other ‘things’, but I am constantly reducing the ‘stuff’ that I have. I am building my own home from timber sourced from local native forests in a sustainable way, I have solar power with a backup diesel generator, a solar hot water system, chooks, and will soon add some cattle, as well as aquaponics providing fish and vegetables and an orchard (replanted this year, as most of our trees died off during the drought).
I am not self-sufficient by any means, but I am slowly requiring less resource inputs from
outside of my property. We use about 20l of diesel per month to cover our power requirements from the backup generator each month. When it is overcast, solar cells do not work very well, and I only have enough battery capacity for about 3 days. I will be making some vertical wind turbines to reduce our diesel requirements.
We harvest all of our water from rain – some stored in dams for the gardens, orchard and aquaponics (doesn’t use very much), with household water for drinking, washing, cooking and showering coming from a 27,500 litre tank. Once I have the verandahs on the house completed, I intend to install a 250,000 litre tank to store the water from a combined catchment of 350 square metres. Each millimetre of rain provides 1 litre of water per square metre of roof area (350 square metres by 660 mm = 231,000).
Future posts are going to expand on what we can do and what I am doing in particular to reduce my impact on the planet’s resources.
It has been said that energy is the lifeblood of our civilisation. The rise of energy production has propelled our civilisation forward. As stated in another post, our civilisation is already past peak oil and probably even past peak water. We must urgently reduce our energy consumption as it produces huge amounts of carbon dioxide which is a large component of climate change and the destruction of ecosystems. Energy costs are rising steadily, and will increase much more over the coming years due to scarcity.
So what can you do?
You can encourage the production of “green energy” by buying it on your electricity. I live off-grid by choice. It was going to cost over $100,000 ten years ago to be connected to mains power. We decided to install a solar energy system, that provides enough for our simple lifestyle, even with 3 to 4 days of heavily overcast weather. Yes, we do have a backup diesel generator for those periods with not enough sunshine, and to run the welder and other high energy consuming appliances. I generally use less that $20 per month on diesel. In the near future, I will be constructing some vertical wind turbines to provide power during windy and normally overcast weather to supplement the solar panels (8 off 125 watts at 24 volts).
You can also install your own solar panels and sell the power generated back into the grid. Many thousands of people do this, and many even receive a cheque at the end of each billing period. You can reduce your energy consumption in your house be turning off appliances at the power point, not just by putting onto standby with the remote control. Sure, they take a little longer to start up, and you need to actually go the power point to switch them (more exercise). You can choose to set your thermostat to 23 or 24C which will generally lower your energy consumption by at least 10%.
Installation of a solar hot water heater with either gas or wood fire backup is also a great money saver. Before installing our current hot water system, we were using a 9kg gas bottle every three weeks for cooking and water heating. Now the same gas bottle is lasting over 2 months. The solar hot water system installed will tolerate down to -15C, and here has to be covered up over summer with shade cloth to prevent the water boiling!
It has been suggested that using electric vehicles is a good idea, and many manufacturers are now providing them. Research has shown, that in many instances, they actually make more pollution and use more energy than traditionally powered vehicles.
The article at http://newmatilda.com/2012/10/04/renewables-will-win-ballot-box demonstrates how important alternative energy sources are now and will be into the future. For me it is disappointing that so many of our great ideas about alternative energy have been swallowed up by oil companies and bureaucracy. White Cliffs in western NSW had one of the first solar powered generating plants in Australia (http://en.wikipedia.org/wiki/White_Cliffs_Solar_Power_Station), but is now grid connected. Australia should be a world leader in alternative energy, but California is, with is super saline systems and salt energy storage systems.
The sun is a great nuclear power station, that in turn creates light and weather systems here on our planet. All alternative energy systems make use of the energy that originates from the sun. I believe that we do not need more nuclear or coal or gas powered generator systems. We have enough sources already, and all that is required is people power and government direction.
Growing up on a dairy farm meant that we always had fresh milk, and Grandma used to have a wonderful vegetable garden using aged cow manure as a fertilizer and soil conditioner.
Fast forward nearly 50 years, and I now live a long way from the dairy farm, in a fairly arid area. When we moved onto the bush block, I tried gardening using traditional methods. Sure, I managed to grow some herbs, and salads, but that was all. The tree roots would rob the plants of moisture, and so after a couple of years changed. I made a tunnel using reinforcing mesh and 50% shade cloth. The garden beds were lined with builders plastic and filled with aged cow manure and soil. It worked very well, producing good quantities of vegetables and herbs year round. I even managed to have tomatoes and bell peppers survive over winter with our heavy frosts.
It took about 3 years and the tree roots penetrated the plastic garden bed liners, and production dropped dramatically as the trees stole the moisture. While living and working in Alice Springs, we stayed with friends who had created an aquaponics system using recycled bath tubs and spas, with 200 silver perch. It worked very well, and provided a lot of herbs and vegetables for everyone staying there.
I have tried hydroponics before. It worked well, but I had to keep buying the minerals and fertilizer mix, as well as dumping the water every so often. I considered the dumping of the water a huge waste, especially here, were we get 600mm annual rainfall and 2.5m of evaporation.
I’ve tried aquaculture, but because I never had a large, continually flowing source of water, could never stock the fish densely enough to make it worthwhile. Also, the water had to be dumped occasionally.
With aquaponics – a combination of aquaculture and hydroponics, the media in the growing beds act as a biological filter for the fish. To me, it is the best of both worlds, and I get fresh fish as well as vegetables.. According to research, it takes only 10% of the water to grow the same amount of vegetables as would grow in soil.
There are many different ways to set up an aquaponics system, ranging from small fish tank size with one or two small growbeds suitable for the balcony or the edge of the patio, to full grown commercial systems producing tonnes of fish and vegetables. A cheap way of getting started, that works well is to use IBCs – International Bulk Containers – of 1000l capacity. As long as the ones used have not contained chemicals, they can be cleaned and used. For more information about many different ways of using these containers, visit and download the free IBC of Aquaponics publication from http://www.backyardaquaponics.com/Travis/IBCofAquaponics1.pdf. There are also many YouTube videos available to view to see how the systems work.
After about 6 months of research and design, I started getting mine established. I was given 6 IBCs, and I had a couple that I used to use for water carting. My system is referred to as a CHOP2 system – that is the sump tank pump is below the growbeds, and pumps about 80% of the water through the grow beds, and about 20% through the fish tank. The fish produce ammonia, which the bacteria in the grow bed media convert to nitrites and eventually to nitrates which the plants can use.
Oxfam has stated that for the sixth time in the last 11 years, the world is going to consume more food than it produces. This is caused by unusual weather conditions in the USA, Russia, and other major food exporting countries. It is estimated that staple food prices will double in the next 20 years, which will be disasterous for poor people around the world.
So, you wonder, what does this have to do with you? For starters, more of your income is going to go to paying for the food you and your family need to survive. More people are going to be hungry, and get more diseases, and more people will die because of malnutrition (especially children, who are most susceptible).
What can you do? Well, you can do a number of things.
You could start a small garden at your home on your balconey or in your yard or on the road verge.
You could join or start a community garden program.
You could shop at your local farmers market, which in turn encourages them to grow more food and sell locally.
You could contact a local farmer and buy direct from them or even form a cooperative with others to do the same.
If you have the room, you could start your own aquaponics project. From the space of a single car carport, you should be able to produce enough food to feed 4 people.
Why has earth-wall construction been so little used in past years? The answer is that as there is nothing to sell there are few to extol its merits. G.F. Middleton, Earth Wall Construction 1952.
For centuries, earth and water have been used for construction in Africa, Asia and the Americas. It is estimated that around 20% of all the buildings on the planet are build from earth. Earth is very little used in Australia. It is strong, durable and well suited to the Australian climate. It does have problems meeting the energy ratings as required for new buildings, but after having lived in mud brick homes and 5-star energy rated homes in cold climates, I know which one I prefer, as do many other people.
Earth walls are fireproof, cheap (requiring labour and minimal mechanical inputs), dry and hygienic. It exists at every building site, and many times is carted away. The walls are cool in summer and warm in winter, and white ants and insects (other than mud wasps, which collect pest insects anyway) don’t tunnel in the walls.
Muscle power and water are essential ingredients, along with the sun to dry them. The first buildings in Australia in Sydney were wattle (thin sticks) and daub (mud) mixed with straw. Many of the villages in Africa and South America are still built using this ancient method.
Today, most earth walls are built from rammed earth (pise) or unfired mudbricks (which I have used). Pise is made by putting damp soil into a movable framework and ramming it. It was introduced into Normandy by the Romans, and spread from there. It is still widely used in China and other Asian countries.
Mudbricks have been used for well over 8000 years to build shelters in hot, dry, arid
countries in the Middle East, Africa, China, Mexico and South America. Mud is placed into a bottomless mould to make blocks, which are then allowed to dry, and then stacked near where they are to be used.
When I started building, I had lots of time, not much muscle power, no mechanical power, some water and lots of dirt. I had helped my daughter made some mudbricks as well as putting them into walls. It is a bit hard on the back, and hands. We used an old bathtub for mixing. We would make a batch in the morning, mix and let soak all day, then make the bricks in the afternoon, and then make another mix, so that it would ready for putting out the following morning. This method gave
us 60 bricks or so per day. Doesn’t seem like many, but after 10 days, we had over 600, which was enough for the small cottage. I have used the same method here, sometimes doing 3 mixes in a day giving close to 100 bricks per day without much effort.
Slowly but surely the house walls are coming along. I put up 4 courses, then some building strapping for ensuring the wall is solid and fastened to the log poles holding the roof down, then another 4 courses. This is enough for the day, otherwise the mud mortar gets squeezed out by the weight of the bricks. I get to work in the shade most of the time, which suits my skin.
The house is not yet finished – a work in progress, but at current rate, will be airtight and warm for next winter, with about 1000 bricks still to make. Once the house is finished, we are planning on making a couple of 2 bedroom units and another 4 bedroom cottage for people to stay in. The idea is that they work 4-6 hours per day in order to pay for accommodation and their food from the aquaponics system.
There are many people who for circumstances beyond their control, are unable to find somewhere to live that is affordable. Towns and cities are not good places for lots of people, and this is provide some alternative for a few people while they get their lives back together with the assistance of counselling, art therapy, and meditation.
Geraldton Wax is a flowering shrub with white or pink flowers that comes from Western Australia. It is very similar to Tea Tree and the flowers last a long time, making it very popular in the cut flower trade.
This plant is supposed to be frost tender – the temperatures go down to -6C here. Without any care over the last 3 years, it has survived and this is the 2012 flowering – absolutely magnificent (well, in my opinion). There aren’t many local shrubs that can match it. It loves sandy soil in moderate to full sun, and will withstand dry periods, making it perfect for growing in my local climate. It is short-lived in high humidity areas, like along the east coast of Australia.

Native bee coming in for nectar
Many of my neighbours have tried growing these without success. Their properties are lower down, and receive heavier, longer frosts that I do.
Next year, I intend to plant many more these to provide extra food for the insects and birds. Since moving to this place, our plantings of calistemons and grevilleas has increased the bird population as well as our local native stingless bees, as they now have food when the local natives are not flowering. We are surrounded by native forest, so all we are doing is supplementing their diets.
I started off my aquaponics with Seasol fertilizer. I currently don’t have any fish in the system, as I have not been able to source any (the hatcheries are all sold out). I’ve been running on a pure source of ammonia, checking levels daily.
Some of the newly emerging leaves have yellow edges. Normally the waste from the fish provides the ammonia and other nutrients required. Sometimes potassium and iron can be lacking, which can result in leaf yellowing.
Some web sites suggest adding a few rusty nails along with seaweed extract. I have added the seaweed extract, as well as some iron chelate mixture. This has solved the problem.
When we first moved to this property, I tried to garden using traditional methods i.e. growing plants in soil. Not very successful. I could not keep water up to the plants. The annual rainfall here is 600mm, but we have 2.5m annual evaporation, so their is a large water deficiency.
I then tried raised garden beds with building plastic underneath to try and stop the tree roots stealing the water. Much better production, but after a couple of years, the roots worked their way into the beds.
I tried growing in containers, but that meant watering at least once per day. I tried hydroponics, but was not happy dumping the water every so often due to the build up of salts and minerals. Aquaculture did not produce the food we needed, and obtaining a licence is an expensive exercise.
While working in Alice Springs, we stayed on a property where the owner had made use of old bath tubs and a lined garden pond to create an aquaponics system. He had about 200 silver perch fingerlings in the pond and an old spa bath, with about 20 old bath tubs. The production of vegetables was amazing.
I started reading and learning all I could about this system of plant production, as I thought that it might solve many of the issues that I have here. We are on a similar latitude to Alice Springs, and have a similar climate, with frosts over winter and hot days during summer, and raining whenever it happens (no real set pattern).
