    Paving our market gardens: choosing suburbs over food

    In 1947 the Sydney Basin produced “three quarters of the State’s lettuces, half of the spinach, a third of the cabbages and a quarter of the beans; seventy percent of the State’s poultry farms were in the [Basin] and more than eighteen percent of Sydney’s milk came from the [Basin]”. Sixty years later…

    In 1947 the Sydney Basin produced “three quarters of the State’s lettuces, half of the spinach, a third of the cabbages and a quarter of the beans; seventy percent of the State’s poultry farms were in the [Basin] and more than eighteen percent of Sydney’s milk came from the [Basin]”.

    Sixty years later, the Metropolitan Plan proposes reducing the area of Basin farms to about 600 hectares, through the residential development of 220,000 homes in the north-west and south-west growth areas. The development will pave over 52% or 603 hectares of Sydney’s remaining fresh produce farms. The area devoted to greenhouse vegetables could decline by as much as 60%.

    In 2006, of the 90% of the vegetable growers who produced 90% of Sydney’s fresh vegetables, 40% had market gardens located in the designated urban growth areas with no apparent strategies for their relocation¹.

    Local farmers have economic and social benefits

    Existing agricultural production within the Sydney Basin contributes about $1 billion at the farm gate and $4.5 billion in multiplier effects to the NSW economy². These farmers are producing 12% of the “farm gate value” of NSW primary production using just 1% of the state’s land area.

    Of the $1 billion farm gate production value, vegetables accounted for $250 million per annum (pa), poultry $278 million pa (both worth 40% of NSW production), and cut flowers $185 million pa.

    Peri-urban gardening is also socially valuable. Market gardens have been vital in establishing the livelihoods of successive waves of immigrants. Each wave began cultivating particular crops of fresh vegetables with which they were familiar (and for which their own communities were a captive market).

    They were able to establish a capital base working in factories, restaurants, driving taxis, working on farms and purchasing their own land. They were motivated to be “their own boss”, avoid situations where language was a problem in earning an income, and to avoid being on social security. About 80% of market gardeners are from non-English-speaking backgrounds.

    Everything is interdependent

    Food security in capital cities relies upon interdependent global systems of financial and food markets, political trade agreements, cheap fuel costs in transportation, and sophisticated logistics. Food security implies a constant availability of food.

    Sydney, like most of south-eastern Australia in 2006 – 2009 became vulnerable to drought. Floods and cyclones in Queensland created shortages of some foods, most notably bananas in 2011. NSW already imports 75% of its seafood.

    Sydney is vulnerable to international volatility in market prices for a range of commodities. And should the price of oil escalate, it will make transportation of fresh foods over long distances problematic. For these reasons, Sydney needs its own supply of food.

    Fresh food means better health

    In October 2009, a Victorian Local Government Association report discussed the issue of food insecurity from the perspective of the steady decline of agricultural production close to Melbourne. The study linked the loss of peri-urban agricultural production with food security, land use planning, health and jobs.

    When food is 40% to 70% of your weekly budget, any price rise can be life threatening. There were food riots in 28 countries in 2008 when world prices doubled and tripled for dietary staples – wheat, rice and corn/maize. We are fortunate that food only comprises around 15% of the weekly budget in Australia. We are fortunate, too, that we can afford to throw out some 30% of the food we purchase.

    What’s more important: development or food?

    Other stakeholders – such as land developers – responded positively to NSW’s release of the planned growth regions. Their not-unexpected perspective was captured by the headline: Grow suburbs, not vegies.

    These proponents of growth and development look to technology to offer “industrial” food production. They want to use techniques such as capital-intensive computer-controlled glasshouses using hydroponics technology, and large transport hubs to organise food distribution by road to Sydney from production beyond the Sydney Basin.

    Real estate developers have a substantial stake in the implementation of the State Metropolitan Plan growth areas. Preserving Sydney’s urban and peri-urban farms will apparently “cripple” the city’s growth, decreasing housing and rental stocks as population growth increases and forcing up prices. Mr Aaron Gadiel, CEO of the Urban Taskforce, asks“ “should we … deprive ourselves of housing and job-creating industries to prop up an industry which is not economically viable?”.

    But I wonder: should local, fresh food production be equated with development in terms of priorities?

        Johnathon, you don’t ask the most relevant question for this, the Free Trade, Ultra Competitive trading world, based on a Globe challenged by over population, diminishing water and food sources, and the proliferation of nuclear weapons.
        You could answer: What percentage of the build of 220,000 homes will be exported? (Expect zero). How much Debt will Australia incur to fund the roads, hospitals, sewerage, schools, police etc? (Expect an increase). What percentage of the punters inhabiting the 220,000 homes will prove to be net Exporters of Goods and Services during the course of their lives? (Expect 1? 2? percent).
        Nothing proves the corruption of Australian politics more than this story. You have export replacement, immigrant based workforce, doing something for our unsustainable cities, being supplanted on the whims of our great import orientated mega businesses…

        Melbourne is much the same – high quality land disappearing under buildings.
        It’s not necessary – we have lots of low quality land that we could happily pave over for houses and businesses. Further, if our cities were surrounded by a mile or 3 of desert, they’d be better protected from bushfires.
        We need to move inland.

  • This is bigger than climate change. It is a battle to redefine humanity

     

    The summit’s premise is that the age of heroism is over. We have entered the age of accommodation. No longer may we live without restraint. No longer may we swing our fists regardless of whose nose might be in the way. In everything we do we must now be mindful of the lives of others, cautious, constrained, meticulous. We may no longer live in the moment, as if there were no tomorrow.

    This is a meeting about chemicals: the greenhouse gases insulating the atmosphere. But it is also a battle between two world views. The angry men who seek to derail this agreement, and all such limits on their self-fulfilment, have understood this better than we have. A new movement, most visible in North America and Australia, but now apparent everywhere, demands to trample on the lives of others as if this were a human right. It will not be constrained by taxes, gun laws, regulations, health and safety, especially by environmental restraints. It knows that fossil fuels have granted the universal ape amplification beyond its Palaeolithic dreams. For a moment, a marvellous, frontier moment, they allowed us to live in blissful mindlessness.

    The angry men know that this golden age has gone; but they cannot find the words for the constraints they hate. Clutching their copies of Atlas Shrugged, they flail around, accusing those who would impede them of communism, fascism, religiosity, misanthropy, but knowing at heart that these restrictions are driven by something far more repulsive to the unrestrained man: the decencies we owe to other human beings.

    I fear this chorus of bullies, but I also sympathise. I lead a mostly peaceful life, but my dreams are haunted by giant aurochs. All those of us whose blood still races are forced to sublimate, to fantasise. In daydreams and video games we find the lives that ecological limits and other people’s interests forbid us to live.

    Humanity is no longer split between conservatives and liberals, reactionaries and progressives, though both sides are informed by the older politics. Today the battle lines are drawn between expanders and restrainers; those who believe that there should be no impediments and those who believe that we must live within limits. The vicious battles we have seen so far between greens and climate change deniers, road safety campaigners and speed freaks, real grassroots groups and corporate-sponsored astroturfers are just the beginning. This war will become much uglier as people kick against the limits that decency demands.

    So here we are, in the land of Beowulf’s heroics, lost in a fog of acronyms and euphemisms, parentheses and exemptions, the deathly diplomacy required to accommodate everyone’s demands. There is no space for heroism here; all passion and power breaks against the needs of others. This is how it should be, though every neurone revolts against it.

    Although the delegates are waking up to the scale of their responsibility, I still believe they will sell us out. Everyone wants his last adventure. Hardly anyone among the official parties can accept the implications of living within our means, of living with tomorrow in mind. There will, they tell themselves, always be another frontier, another means to escape our constraints, to dump our dissatisfactions on other places and other people. Hanging over everything discussed here is the theme that dare not speak its name, always present but never mentioned. Economic growth is the magic formula which allows our conflicts to remain unresolved.

    While economies grow, social justice is unnecessary, as lives can be improved without redistribution. While economies grow, people need not confront their elites. While economies grow, we can keep buying our way out of trouble. But, like the bankers, we stave off trouble today only by multiplying it tomorrow. Through economic growth we are borrowing time at punitive rates of interest. It ensures that any cuts agreed at Copenhagen will eventually be outstripped. Even if we manage to prevent climate breakdown, growth means that it’s only a matter of time before we hit a new constraint, which demands a new global response: oil, water, phosphate, soil. We will lurch from crisis to existential crisis unless we address the underlying cause: perpetual growth cannot be accommodated on a finite planet.

    For all their earnest self-restraint, the negotiators in the plastic city are still not serious, even about climate change. There’s another great unmentionable here: supply. Most of the nation states tussling at Copenhagen have two fossil fuel policies. One is to minimise demand, by encouraging us to reduce our consumption. The other is to maximise supply, by encouraging companies to extract as much from the ground as they can.

     

    We know, from the papers published in Nature in April, that we can use a maximum of 60% of current reserves of coal, oil and gas if the average global temperature is not to rise by more than two degrees. We can burn much less if, as many poorer countries now insist, we seek to prevent the temperature from rising by more than 1.5C. We know that capture and storage will dispose of just a small fraction of the carbon in these fuels. There are two obvious conclusions: governments must decide which existing reserves of fossil fuel are to be left in the ground, and they must introduce a global moratorium on prospecting for new reserves. Neither of these proposals has even been mooted for discussion.

    But somehow this first great global battle between expanders and restrainers must be won and then the battles that lie beyond it – rising consumption, corporate power, economic growth – must begin. If governments don’t show some resolve on climate change, the expanders will seize on the restrainers’ weakness. They will attack – using the same tactics of denial, obfuscation and appeals to self-interest – the other measures that protect people from each other, or which prevent the world’s ecosystems from being destroyed. There is no end to this fight, no line these people will not cross. They too are aware that this a battle to redefine humanity, and they wish to redefine it as a species even more rapacious than it is today.

  • A more considered approach to Biochar

    Geoff Moxham (aka Terrania Geoff) has been working with alternative energy sources and low impact living patterns for many years. His range of pyrolisis equipment is legendary (and visible at Bodgers Hovel)
     
    Geoff joined the Generator to demonstrate the results of his pyrolisis using home made equipment that completely burns all the fuel in biomass without oxygen, leaving the carbon dioxide behind.
     
    This video simply shows the results of pyrolisis with a short discussion about the value of charcoal for the soil.
  • Listener tests new biochar approach

    This week, Dieter has excelled himself. In response to the news story about a NZ venture to microwave biomass and produce charcoal, Dieter took himself outside, grabbed a large handfull of grass clippings and threw them into the microwave.

    He not only sent us a photograph of the results to share with you. He drove into the studio (on his no carbon, electric motor cycle) to show them to us first hand (cracked plate and all). Thanks to Dieter’s pioneering efforts you don’t have to try this at home, kids, we already know the results.

    Of course, we have already raised the issue of dedicating resources to growing forests (or any other biomass) simply to expend more energy microwaving it on the basis that the net result is a reduction in global carbon dioxide. Tim Flannery disagrees with us, so what more can we say?
