THERE WAS a revealing interview on ABC Radio’s RN Drive recently. On Friday 24, May, presenter Patricia Karvelas spoke to James McTavish, the NSW Government’s Regional Town Water Supply Coordinator, about the deepening crisis facing towns throughout the State. Mr McTavish told those of us who don’t already know it that towns as far apart as Dubbo and Tenterfield, Bourke and Molong, are facing real problems as water supplies rapidly diminish and restrictions bite deeper.
He told listeners what some of the problems are – the drought figuring significantly – but unfortunately was a bit light on any long-term solutions. To be fair, he was fronting for a government and, generally speaking, state and federal governments have never been too keen on long-term planning that might affect their election prospects.
There was the usual mention of new dams and the sinking of bores to augment water supplies. Carting in water to some places was also mentioned, but as James McTavish pointed out, carting water to a place like Tenterfield would be inordinately expensive and at best a stop-gap measure.
Mr McTavish also reminded listeners that not only farmers and rural towns are affected; industries in the regions are also at risk. He cited the case of Cobar, a mining town that relies on water pumped from the Bogan River at Nyngan. The mines are the largest user of water in the town and both the mines and township will face severe downturns if the supply is restricted.
Strawberry growers around Stanthorpe, a town in the “Granite Belt” just north of Tenterfield and over the Queensland border, are facing financial hardship as water becomes scarcer. During a recent interview, one grower said a solution was to grow the berries hydroponically under cover, a method that uses, and wastes, less water. However, he noted that present returns on the crop don’t justify the expense of such infrastructure. “People will pay $6 for a Big Mac,” he said, “but if the price of a punnet of strawberries goes above $3, they won’t buy them.”
However, neither the grower nor the interviewer mentioned that the horticultural industry regularly ploughs-in or dumps hundreds, sometimes thousands of tonnes of crops if market prices are low.
Just days later, Sydney Water announced that the NSW capital’s water supply – or rather lack of it – was cause for concern.
Again, the bulk of the problem was laid at the feet of the drought. Of course, there is no denying that we are in drought, and for farmer and townie alike it is hard to see past the lack of rain when you are being forced to de-stock or your cherished garden is dying. But is it just the drought and are there solutions, long-term ones?
Drought has our attention because it’s an obvious factor, but there are other things driving the water shortages. Sinking bores to augment water supplies may bring immediate, temporary relief, but in the long term will cause more problems. Most groundwater sources require flooding rivers and good rainfall to replenish them, and they have always been scarce and unreliable commodities in Australia, a continent with the world’s most erratic climate. Groundwater used now may take decades – perhaps centuries – to replenish even if used sparingly. Given the now irrefutable effects of the worsening climate crisis, we have no guarantees either way.
River systems everywhere are suffering badly from misuse, over-extraction and downright mismanagement over the decades and the result is now plain for all to see. What floods do occur are mostly sudden and violent, but long, dry spells are becoming more the norm. The “Bradfield Scheme”, a much-discredited plan to dam tropical rivers and divert their waters into the deserts, is again getting air time – as are proposals to tap “fossil aquifers” in the tropical north.
The lush, sub-tropical north of NSW was in drought until recently, and over the Top End, this year’s monsoon was almost a non-event; This at a time when Darwin authorities are expressing concern over the depletion of groundwater supplies in parts of the city. Our “southern” monsoon has never been as reliable as the rains further north, and even those are now becoming more erratic. In fact, there are fears that changes in Himalaya ice cover and other factors will eventually lead to the failure of the northern monsoon, with catastrophic results for a sizeable chunk of the world’s population, not to mention the global economy and migratory pressures on other regions.
The pity is that the writing has been on the wall for decades, but those who tried to draw attention to it were at best ignored and at worst pilloried and ridiculed. If Australia – and the world – had begun action thirty years ago, then the task ahead would have been easier and the costs spread over a longer period, but that window has closed. Action is required now, and nations are going to have to cooperate as never before in human history. What can Australia do?
The irrigation industry obviously needs an overhaul, along with regulation of the crops grown. It his hard to argue a case for growing crops requiring vast amounts of water – crops such as almonds, wine grapes, cotton and rice – in marginal country on a continent that sits mainly in the Tropic Arid Zone. Yet we do, and in huge quantities. Sadly, the huge increases in plantings of almonds, and to a lesser extent, wine grapes, are, like the national obsession with coffee, in response to a created demand.
Irrigation on the scale at which it is now practiced is unsustainable in this country; dryland cropping and grazing are really the only viable alternatives when it comes to broadacre farming. Aided by scientific research and a growing acceptance of Indigenous land-management techniques, Australia’s farmers and graziers have made an enormous contribution to alleviating, and in some cases almost reversing, the damage done in the past.
Governments at all levels also need to step up; farmers cannot be expected to address the problems of over-clearing and land degradation alone. Reforestation is of vital importance to future drought management strategies and to combat the climate crisis. Remediation projects on an imaginative scale should be viewed as infrastructure projects that would employ many thousands of people. Rather than stigmatising such national efforts as “work for the dole” schemes, they should be promoted as works of national importance.
If we rely on our dryland farmers to produce exports and feed the nation, then insurance must be looked at. Insurance providers are already factoring in the climate crisis and governments must enter into dialogue to ensure our farmers are equitably treated. Funding to the CSIRO must be restored as a matter of national urgency, and the BOM must be adequately resourced.
And while we wring our hands over dwindling water resources and the plight of farmers, governments continue to issue exploration permits for coal-seam gas exploration and other extractive industries that disrupt or render unusable the water resources on which our agricultural and pastoral industries rely. Political parties praise our “clean green” agriculturalists, weep crocodile tears over the “bush battlers” and “pray for rain” at every photo opportunity, then chide groups such as the Knitting Nannas and Lock The Gate Alliance for trying to protect the resources on which agriculture depends.
The water from town treatment plants needs to be utilised. Adelaide’s “Green Belt” has long been sustained by recycled water, and this is something that should be repeated all over Australia – and not only in the capitals. Smaller centres could be assisted in establishing combined aquaculture and horticulture enterprises based on waste water and other imaginative projects.
Politicians are now carping over the costs of mitigating the climate crisis: “We must reduce emissions but not at the expense of the economy”, is often repeated. If we don’t act now, all else becomes irrelevant. The crisis we are facing is far-reaching and real. Most politicians were silent about the costs of following the USA into Vietnam and Iraq – futile exercises of absolutely no benefit to anybody except perhaps the warlords who control the military-industrial complex – yet it seems that the climate crisis is of lesser importance than the whims of US Presidents.
