I've been looking around for ideas to keep cool when you could fry
eggs on the footpath outside. Heres some of the ideas we tried:

1. Pin up a bed sheet or blankets outside your windows. The key is to
do it outside rather than inside - you want to stop the heat before it
enters the your house - not afterwards. Also try to leave a gap
between the barrier (sheet, blanket etc) and the wall or glass of your
home - that way you'll get less heat transfer. Here's a guy who used
$5 reflective blankets to keep his home cool (just make sure you don't
position the blanket so that it bounces the heat somewhere you don't
want it - you might end up frying your garden).

2. Put a wet blanket over the top of the car and cover all the windows
(this didn't harm my duco at all - but try it at your own risk).

3. Cut the bottoms off water bottles, dig them neck down in the soil
beside sensitive plants and fill with water - this should drain into
the soil gradually throughout the day. You can cover plants likely to
burn with bed sheets too - pick a light colour to reflect heat. Of
course you can always take the attitude of my friend Tim, and see days
like Friday as a form of natural selection - let the heat kill of the
tender ones, and replace them with some tougher plants.

and the best one of all...

4. Run away. Go stay in a 5 star hotel with a pool and air con. We did
this on Friday night, and it was fantastic. I figure that the hotel is
cooling the whole building anyway - and for the 5-6 nights of the year
that are so ridiculously hot that good passive design and fans can't
cope - it's a better option than shelling out for an air conditioning
system which is just going to contribute to pushing up peak demand and
blackouts.

Economic growth may one day turn out to be a curse rather than a good.

Hannah Arendt

A very Faustian choice is upon us: whether to accept our corrosive and risky behavior as the unavoidable price of population and economic growth, or to take stock of ourselves and search for a new environmental ethic.

Edward O. Wilson

• thinking about the problem and admitting that things are not working...that they're really really not working.
• not letting the urgent always take precedent over the important (I think Leo said something like this in the West Wing episode '365 days').
• growing to understand ourselves; paying attention to our behavior, and recognising the cultural forces which drive us to behave in certain ways. We need to learn to see the paradigms we operate within which function to make some aspects of our lives visible (this deodorant looks cool, I'll buy it), and render other aspects invisible (the product will last a month but it's packaging will last an aeon in landfill).
• recognising that if we continue to trust in a kind of laissez-faire-capitalism style of philosophy that suggests that if we leave things to their own devices everything will work itself out, we just might end up with a world we don't want to live in...or worse.
• seeing that the economic system as we know it (with the underlying requirement of constant growth) isn't inevitable. It is a relatively new idea historically (200 years or so) and that there are lots of other existing models for barter and exchange of goods which might be more sustainable.

We came all this way to explore the moon, and the most important thing is that we discovered the earth.

— William Anders

William Anders left Texas faster than any human had ever traveled before - rockets launched him into space and he and the other crew of the Apollo 8 traveled for three days before reaching the moon and becoming the first people ever to see its hidden side.

On Christmas Eve 1968, while on the dark side of the moon William Anders took this photograph of the distant earth rising over the horizon. Originally labeled image AS8-14-2383, as it captured the public imagination it became known simply as 'Earthrise'.

This photograph triggered a fundamental paradigm shift; it changed the way we thought about ourselves and our relationships to each other and the environment. This image allowed us to conceive of 'the planet' as opposed to 'the world', and seeing the earth floating; beautiful, tiny and fragile in the void of space inspired a movement of environmental consciousness which is still active today. This Christmas Eve will be the fortieth anniversary of breaking of that old gestalt - which is worth a little reflection perhaps.

No one, it has been said, will ever look at the Moon in the same way again. More significantly can one say that no one will ever look at the earth in the same way. Man had to free himself from earth to perceive both its diminutive place in a solar system and its inestimable value as a life -fostering planet. As earthmen, we may have taken another step into adulthood. We can see our planet earth with detachment, with tenderness, with some shame and pity, but at last also with love.

— Anne Morrow Lindbergh, 'Earth Shine,' 1969.

I was sitting at home working a moment ago when I heard the sound of what I thought was a tennis ball hitting the window high up on the side of our house.

I looked up as a bird fell into the court yard, and I watched it as it lay on the ground where it landed and twitched a little before lying still. A indigenous Little Wattlebird, dead.

And I feel faintly ridiculous about this, but the bird dying has upset me a little. I'm not used to watching a creature die. And I'm not used to being confronted by my impact on the natural world as directly as this.

This whole blog is supposed to be about how to make my neighbourhood more ecologically sustainable, but for this bird the fact my house existed at all, with it's unnatural glass surfaces, was enough. And right now, faced with the reality of this little prone body, the life of even one wild bird seems like a high price to pay.

I'm feeling a little guilty.

I stumbled across this car parking stand-off in Calton. The cars are parked behind an apartment block. The laminated note attached to the toy car reads:

"DO NOT REMOVE. This is the property of unit one. We pay rent for this carpark and thus shall utilize it for whatever vehicle we see fit".

At the moment all the fresh drinking water we use to shower in and to do our laundry is going straight down the drain after a single use. On top of that, most of us are using more fresh drinking water to water our gardens.

This is a shame - because treating greywater on a neighbourhood scale is pretty straightforward - in principle at least.

Do you ever wonder if it might be easier to generate the sort of massive changes we need to make to our lifestyles if we were engaged in some kind of war or a pitched battle?

The problem is that when it comes to environmental issues there really is no enemy. We can direct our aggression to a few amorphous corporate entities, and maybe people who drive massive 4x4 SUV’s if you're so inclined. But really, the actual enemy is ourselves.

This poses a dilemma because we’re really not good at coping with the ‘enemy within’. The enemy which is us.

Improving our sustainability is more like going on a diet than it is like going to war, and we all know how successful the average diet is.

We’re simply better at initiating changes to our attitudes and lifestyles when we’re at war – which is probably why we try to cast problems into that mould even when it’s completely counter productive to do so, perhaps we create the war against drugs, or attack Iran and Afghanistan as part of a war against ‘terrorism’ because that's the only way we know how to respond.

So anyway. Good news. I think I found someone who can be our scapegoat...our environmental bogey-man.

I’ve been reading Bill Bryson’s “A Short History of Nearly Everything” – fascinating and entertaining in equal measures – and he recounts the story of an engineer come chemist called Thomas Midgley Jr.

Thomas Midgley Jr. is the devil. Except he's not really. He's just a scientist with few scruples who was well respected by many in his day, and that is what makes this sorry tale so scary.

If you ever get a chance to borrow a time-machine to travel backwards in history in order to ensure someone is never born, consider visiting Mr and Mrs Thomas Midgley Sr.

Thomas Midgley Sr. was an inventor, and his son Thomas Midgley Jr. initially trained as an engineer, but eventually took after his father to become an inventor as well.

The first problem Midgley turned his attention to was engine knock and associated fuel efficiency. His unfortunate solution was to add a lead solution to the fuel (tetra-ethyl lead or TEL). There were less toxic solutions available which he discovered at the same time, but lead was the cheapest, had the least offensive odour and was the most efficient, so Midgley ran with it. And the evidence indicates that he ran with it while being fully aware of the toxic affects of lead in the atmosphere and in the human body.

People started dying almost immediately from the affects of his innovation. By the mid 1920’s more than 40 factory workers who produced the lead fortified fuel for Ethyl (the corporation who produced the product) were dead or deranged. The Ethyl factory in Deepwater was nicknamed the 'House of Butterflies’ by the workers because of the hallucinations they experienced while working there.

Midgley’s crime is that he knowingly introduced a "creeping and malicious poison" into the environment, and also that he then deliberately assisted in the large scale corporate cover up which followed for the next 50-60 years.

TEL is still being produced, although we stopped adding it to fuel in the 1980’s. Of course we’re stuck with the lead; which is now in the atmosphere forever.

So just in case you think that’s not enough to earn Midgley some kind of serious enemy-of-the-planet status – just wait, there’s more...

The second problem Midgley addressed was the serious one of poisonous gases leaking from early refrigerators.

“Midgley set out to create a gas that was stable, nonflammable, noncorrosive, and safe to breathe. With an instinct for the regrettable that was almost uncanny, he invented chlorofluorocarbons, or CFCs.”

Bill Bryson, A Short History of Nearly Everything

For the first time in my life I saw the horizon as a curved line. It was accentuated by a thin seam of dark blue light—our atmosphere. Obviously this was not the ocean of air I had been told it was so many times in my life. I was terrified by its fragile appearance.

Monday was the first day of spring here.

I celebrated by biking around in the sunshine with my daughter, doing an informal playground tour, and chatting happily to people we met about the weather.

And today is another beautiful spring day. Walking around in a t-shirt (maybe being a little over confident of the sun) I found myself thinking about how today was the perfect day to go hunting for Easter eggs. But of course we don't do Easter in spring here - we do it in Autumn just as the weather is getting grimmer and the winter winds are starting.

It's crazy stuff, after all Eostre was the goddess of spring, and the Christian celebration is supposed to be about rebirth. On the first warm spring days like today I feel like celebrating all those things - but in March/April - it's all academic.

And our Christmas is even more ridiculous. Christmas is a profoundly wintery event: It’s holly, puddings, candles, yule logs and all those reworkings of pre-Christian Winter solstice celebrations (Yule, Natalis Solis Invicti, Saturnalia).

And all these things are beautiful on the coldest, shortest, darkest day of the year…Christmas is supposed to be a little twinkling light in a dark cold place.

But we celebrate it right in the middle of summer. Hot turkey dinners, sweaty tinsel and fake snow in the heat and dust. It’s a little sad...we should be dancing around maypoles instead.

I'm not saying we should do the whole Christmas in July thing- but I think it's a shame. It's a shame because when we have a beautiful spring day like today - we have no way of celebrating it.

And I also wonder whether this serves to increase our sense of disconnection from the landscape and the ecological systems that we exist within.

When the people who established the city of Melbourne arrived, they bought with them the Roman calendar, their northern celebrations, and a year which is divided into four seasons - along with their ideas about the landscape and how it works. Those of us who still live here have inherited all of these things.

How many of us still think of winter as a time of dormancy, and summer as a time of growth and life, rather than something closer to the opposite? Or else think of wild fire as a purely destructive force, rather than a process which brings life and regeneration, without which many fragile ecosystems would die?

The Wurundjeri people certainly didn't have a 4 season calendar; they based their seasons on the local weather conditions, and the behaviour of plants and animals. I've drawn up a (possible/approximate) Wurundjeri calendar above, alongside the traditional Roman seasons, and a seasonal calendar created by researches looking at the climate and ecosystem of the Upper Yarra. Makes for interesting comparison.

Would we be less disconnected from our environment if we had seasons that were more responsive to the local ecosystem? What would happen if we didn't think about the seasons as Spring, Summer, Autumn and Winter - but as something like Pre-spring, True Spring, High Summer, Dry Summer (Old man summer), Autumn and Winter?

And if, instead of being fixed to the climatic conditions of far off European landscapes, those six seasons were linked to the markers of actual seasonal changes as they happen here - like summer grasses flowering, the appearance of kangaroo apples or of tadpoles spawning in the Yarra?

I've been reading about these bioregional thinking questions – adapted by Bill Devall and George Sessions in their book Deep Ecology. It's an interesting test to do on yourself - I can't answer more than half - which is a bit depressing. I tested Adrian (my partner), and he did quite well actually. Anyway, good luck, let me know how you go...

1. Trace the water you drink from precipitation to tap.

2. How many days till the moon is full? (Plus or minus a couple of days.)

3. Describe the soil around your home

4. From what direction do winter storms generally come in your region?

5. Where does your garbage go?

6. How long is the growing season where you live?

7. Name five resident birds and any migratory birds in your area.

8. What primary geological event process influenced the land form where you live?

9. From where you are reading this, point north.

10. Were the stars out last night?

When I started writing this blog I was planning to focus on small interventions on a scale just slightly larger than a single household. I wanted to look at the possibility of getting together with the people next door and sharing resources; like for example having a solar hot water system which is shared between five houses, or organising an organic food buying co-op, or maybe a car club.

What I've discovered is that a lot of the sustainability improvements which would be most effective as a way of reducing our carbon emissions or water usage either work on the scale of the individual house - or else on the scale of a neighbourhood (150-250 houses).


Because small decentralised systems tend to have a smaller ecological 'footprint', are more efficient and just generally more sustainable than large scale centrally organised systems, it makes sense to start thinking about providing as much of our energy, food, water and social/cultural resources locally.

But how do we make that work? How can we organise ourselves on a neighborhood scale to enable the implementation of local sustainable systems?

I'm trying to think of some useful models. Here in Melbourne I can't think of many organisations which work on that scale: Our local government functions on a much larger scale - the City of Yarra, our local council, manages something like the equivalent of more than 100 neighbourhoods. Too big.

Maybe a local school is a useful model? A lot of schools would have 200 or more families enrolled, and they would be managed locally by a school board with some key decisions or design processes being carried out on a regional or state level.

Come to think of it - the toy library we go to in Clifton Hill would have 200 or so families involved. They have one or two full time paid staff hired by the council and these staff manage the library, gather fees and organise the families to volunteer their time two to three times a year.

Perhaps it could work similarly here, council could hire a someone to manage or facilitate local neighbourhood-scale groups. This person could provide advice and some financial support while allowing the impetus, and most of the key decisions to come from the residents. Large scale, expensive or potentially hazardous interventions - like black water treatment, could be handled by council in the same way they would deal with proposals from any developer.

In 1994 our then premier Jeff Kennett merged three local councils (Richmond, Collingwood and Fitzroy) and parts of the City of Melbourne and City of Northcote into the City of Yarra, forming one big mega-council. I believe the idea was to improve efficiency and reduce costs, and maybe increase quality of decision making & outcomes - and I imagine that in some areas it was probably effective in doing so. The downside is that government on this scale makes it difficult for the individual voice to be heard. It becomes difficult for small scale neighborhood lead interventions to be handled effectively. And the anonymity and professionalising of local government on a larger scale tends to discourage citizen participation.

I don't know how many people lived in the old City of Collingwood, but there are almost 70 000 people living in the City of Yarra now. Thats almost ten times larger than Christopher Alexander's ideal of the 'Community of 7000'. And ten times larger than Jefferson's 'ward republics'.

What we need is new models to enable us to control our energy, our water, our waste and other resources on a neighbourhood scale. But what are they? Anyone have any ideas?

I've been looking at an interesting blog called GreenRenters...

They say they're trying to fill a gap in the 'conversation' about sustainable living - because most information and marketing is addressed at homeowners, who are able to make structural changes to their property, and are less transient in their address.

As renters ourselves I can certainly relate. As energy prices rise it will be interesting to see if government start to mandate the provision of things like insulation and draft proofing in rental houses. Because there's no doubt that living in a badly designed/fitted home can cost you a packet in energy each quarter.

GreenRenters has got some nice vegetable recipes too, they even look delicious enough to maybe convert a meat lover like me...

I've been writing a post on possible strategies for dealing with stormwater in our neighbourhood (inspired by the wet wet day we've had today). But I thought I might post a quick roundup on the weeks water news...

Water costs tipped to more than double
Because of the cost of new infrastructure, and the fact that the water supplies are at 30.6%, down about 5% from this time last year. So maybe, contrary to my earlier suggestion, an investment in water infrastructure could end up paying for itself afterall...

and...

Bizarre solutions to water crisis
Apparently someone in the Queenland government said something about shipping water from Japan.

and...

Rainwater tanks could save public $600m
Taxpayers could save big money if all new houses installed tanks and raingardens - apparently a lot of that saving is from reducing the amount of water which enters the stormwater system.

Thanks to snap for putting me onto 'quietrevolution' in the uk. These guys are making a commercial turbine designed for urban areas, where wind speeds are lower and tend to change direction more frequently. Apparently the helix design significantly reduces vibration and noise, which would certainly make them easier to live next to.

There's no doubt this one is elegant as well. And as you can see in the image below - has significantly less visual impact than a traditional wind turbine, and less problems with shadows too I'd imagine.

Still it's 5m tall plus mast, and not cheap - you wont get much change from $90 000, and that doesn't include footings (foundations), although I imagine it does take into account all the sparky work.

Not sure what the payoff period would be for one - of course that would depend on the amount of energy it could generate, which in turn would depend on the specific wind conditions of your site.

I'm not sure how windy our neighbourhood is. Alexander Parade would probably be our best bet for picking up a few gusts, but I imagine we would have to measure the specific location we wanted to use for a period of time before we'd have useful figures on productivity.

The quietrevolution mob are working on smaller and cheaper turbine for residential use - but it's not due to be released until 2009.
