Australia has a complex relationship with the dingo Angus Emmott, Author provided

Vast, ancient, nutrient-poor, with wild swings between droughts, floods and fires: this describes much of the Australian continent. Livestock grazing and farming in such a land is certainly not without its challenges.

Where we’ve failed to work with the local conditions, we see barren plains, dust storms, the extinction of native species, and the repossession of properties by banks, among many ills.

But such a dire picture is far from universal, and belies the fact that many who live on the land are also among our most innovative land managers. Many projects offer potential benefits for livestock production and the environment alike, but without support progress may be hindered.

Putting dingoes to work

One of the most contentious examples involves encouraging dingoes. Many pastoral areas require land managers to take “all reasonable and practical steps” to manage the risk of dingoes, which are classed as pest animals.

But a growing body of research argues that dingoes can be effective at controlling kangaroo and feral goat populations, especially on cattle stations.

A Western Australian couple, David Pollock and Frances Jones, were recently featured on Australian Story for their decision to regenerate their property, Wooleen, by de-stocking, encouraging local flora and fauna, and investing in ecotourism.

Their neighbours, including sheep graziers whose stock are vulnerable to dingoes, feel this is an irresponsible decision. Graziers have a mandate to control dingoes (“wild dogs”, to many) and dingo-domestic dog hybrids — which can’t be easily and reliably distinguished in the wild.

Dingoes are known to be very effective at controlling kangaroo populations. Angus Emmott

While the impacts and merits of encouraging dingoes in sheep country are hotly debated, their role in the management of cattle stations is much better understood. But restrictive legislation and the stigma attached to dingoes are frustrating for those who see them as having a vital ecological and economic role for their properties.

Queensland grazier Angus Emmott writes that his beef cattle enterprise, Noonbah station, has benefited from leaving dingoes and kangaroos alone:

We run a beef cattle enterprise in the top end of the Queensland channel country, southwest of Longreach. As a part of our management plan, we leave the dingoes and the ’roos alone. We see a range of benefits to our operation.

When the dingoes don’t have their social structure disrupted by poison baiting, trapping and shooting, only the apex bitch breeds, once a year at most. These family groups have strictly defined ranges, and they kill or chase off other wild dogs or dingoes that intrude. They also keep kangaroos down to very low numbers, which is a huge benefit in regards to pasture growth and being able to rest our paddocks. The dingoes also keep down feral pig, cat and fox numbers.

Yes, dingoes do take some of our calves, but the benefits of pasture growth and feral animal control result in a net benefit of better land condition and a greater dollar return. Dingoes also benefit biodiversity conservation and soil condition. We acknowledge this management model does not work in sheep country, including for some of our nearby neighbours, and in these cases we need to look at different forms of management, such as fencing and/or companion and guardian animals.

Research supports the financial benefits of this approach in certain circumstances. Some studies have found that, perversely, taking lethal action against dingoes can increase the incidence of attacks on stock and boost the population of herbivores that compete with cattle for pasture.

Solutions for protecting livestock against attack, such as guardian dogs, are also at hand and may be considerably cheaper than constructing and maintaining extensive predator-proof fences. Livestock guardian dogs have been shown to be effective in numerous locations across Australia, on large and small grazing properties. But investment from state and federal government (and related agencies) aimed at encouraging such innovation has been lacking.

Kangaroos can become very abundant following rain and without control by dingoes. Angus Emmott Working with the land

Regardless of whether graziers take the drastic steps seen at Wooleen, now is the time to reflect on the direction of Australia’s land management.

If we’re to overcome the many challenges we face, including the impacts of climate change on food production, then we need to support the bold new thinking emerging from rural and regional Australia, and our scientific institutions.

Such ideas could include making better use of native animals – better suited to Australian conditions – as sources of meat, and reforming land use legislation to allow new industries.

Seeing some of the worst land degradation first hand it’s easy to think that it’s all too hard and that environmental repair will take decades, if not centuries. This can invite inertia and apathy, the enemies of positive change.

But the stories of Wooleen, Noonbah and other innovators show us what is possible. Science has helped demonstrate ecological repair can happen faster and to a greater extent than many might appreciate.

Big changes certainly carry risks, and these must be managed carefully, but new and sometimes brave ideas will always improve our understanding of the land. Whatever the outcome, such knowledge helps guide better decisions for more sustainable grazing, farming and bio-diverse conservation.

My right hand, flushed with warmth after a day’s walking, is refreshed at the touch of the stone gate post. Standing at the entrance of an abandoned church, I can see it has been worn marble-smooth by the hands of the long-vanished faithful. Centuries of their feet, too, have passed this way and carved a dip into the threshold of one of its ancient doorways.

Although they are faint and rubbed, I’m nonetheless able to trace the radiating spokes of the witches’ marks that decorate the stone lintel. And above the squat and timbered tower a weathercock, long since rusted in place, cannot turn to greet me but instead shudders in the spring breeze.

Originally published in the Manchester Guardian on 17 May 1917

Our Cornish driver said today that here they had had “two winters in one, and that a bad one.” Certainly one does not remember ever to have seen gorse so badly damaged. One thinks of gorse and ling as the hardiest of hardy shrubs, yet here there are great tracts of whin quite sandbrown, and the green, young shoots of the ling are only beginning to prevail over the dead surface. If you beat a bush of ling you have the queer experience of seeing it turn green under the taps of your stick. Another odd thing is that the succulent shoots of the Mesembryanthemum have in many places survived without harm. Of course many square feet of this rampant exotic have been destroyed, but on one sunny slope to the sea we saw a continuous sheet over a well ten feat high and about thirty foot long; it came rambling over the top of this wall, cascading down and then running along the gravel path at the foot, and out over the border and through the fence and on to the cliff beyond, like the ripples of the waves below, after they have broken, invading every crevice with silent haste. This huge tract was deeply green and full of promising buds, yet the gorse bushes with which the fleshy leaves came in contact had been killed by the winter.

Another odd effect of the very late spring is that the blackthorn was overtaken by the gorse, and we have had the very uncommon sight of gorse bushes in full glory of gold and odour, with the frothing among them of blackthorn blossoms, peculiarly thick and snowy this season. In the coves running down to the sea here the blackthorn grows very dwarf and hugs the stones, looking almost like a distinct variety.

Many of Australia’s most carbon-intensive companies are either not participating in the federal government’s flagship Emissions Reduction Fund (ERF), or are adopting a wait-and-see approach, according to our survey of senior executives.

The ERF, introduced in 2014 after the repeal of the carbon tax, is the central component in the government’s policy to reduce greenhouse emissions. Companies can bid for money from an overall fund of A$2.55 billion, to invest in low-carbon technologies and initiatives. Participation is voluntary.

Five ERF auctions have been held, awarding A$2.23 billion so far. However, participation by high-emitting companies has been persistently low.

Some of the funded projects are likely to deliver useful emissions cuts in areas such as forestry, landfill and waste management. But the scheme is yet to reduce emissions reductions in key sectors of the economy such as industry and electricity generation. Our survey underlines concerns that the scheme is not attracting the biggest emitters.

Asking the questions

Our research, titled the Australian Emission Reduction Fund Survey and produced in collaboration with the Carbon Market Institute, was conducted in two rounds.

First, in 2015, we surveyed executives from high-emitting companies in sectors including mining, manufacturing, energy and transport. Then, in 2016, we surveyed executives from firms that had successfully registered carbon-reduction projects under the ERF. Survey respondents represented a broad range of positions, including managing directors, general managers, senior carbon advisers, heads of environmental markets and strategy, and chief executives.

The first-round survey, which was conducted before the first ERF auction and featured 68 participants, showed that 58% of companies planned to “wait and see” before engaging with the ERF. Another 34% said they did not intend to participate in the scheme at all.

One of the main reasons given for non-participation was the fact that the scheme is run as a reverse auction with no guarantee that bids will be successful. This makes it difficult to invest with certainty in the staffing and administration costs of running carbon-reduction projects. One participant told us:

…administrative costs do not make the ERF cost-effective for the scale of abatement opportunities available.

Respondents also told us that there was a lack of guidance on how to understand and participate in the ERF, and uncertainty over the rules of the safeguard mechanism that is meant to help drive demand for carbon credits.

Another issue that most participants highlighted is the inability to make a business case internally and to secure a relatively high price for emissions reductions. One manager emphasised:

Clearly a high price would assist in driving participation, but at the moment the package is not commercially attractive.

Furthermore, some respondents expressed concern over the perceived lack of a wide range of approved methods for cutting carbon. And almost all participants were concerned by policy uncertainty, with one saying:

…there is currently a lack of business certainty regarding carbon policy in the mid to long term.

ERF participants

The results of our second-round survey in 2016, featuring 33 participants from companies that have registered ERF projects, suggested that the financial risk for investors in ERF projects has reduced, having been awarded secure government contracts for delivering carbon reductions. Nevertheless, respondents highlighted a range of concerns about the scheme’s effectiveness.

All respondents highlighted the uncertainty of further funding after the initial A$2.55 billion allocation is exhausted. One participant suggested that the government’s forthcoming climate policy review, to be released this year, should specify exactly how much money the ERF will make available in the future.

Moreover, many respondents expressed doubts that contracts awarded in the ERF’s first four auctions will be completed. This has arisen partly because of a perceived lack of adequate measures to resolve potential disputes between project proponents and land holders. As one respondent told us:

The extent to which landholders understand the legal risks associated with projects is unclear.

Participants also presume that the policy’s safeguard mechanism lacks tight enough “baselines” – the emissions limits beyond which high emitters are required to buy carbon credits. Tough baselines would generate the necessary certainty of a future market, as one respondent explained:

The extent of uncertainty will also be affected by whether the safeguard mechanism is strengthened by reducing baselines, and therefore increasing the need to purchase offsets.

At the Paris climate summit in 2015, Australia pledged to cut carbon emissions by 26-28% below 2005 levels by 2030. But if the government’s flagship emissions-reductions policy is failing to involve the highest-emitting companies, that target begins to look very onerous indeed.

With the government’s major climate change policy review now underway, it is time for the government, other political parties and high-emitting companies to work together to design a climate policy that is economically efficient and environmentally effective. There is no time to “wait and see” when it comes to combating carbon emissions.

The discovery of alarming levels of PCBs, a type of chemical banned 40 years ago, has led scientists to call for an urgent clean-up

The body of Lulu the killer whale was found on jagged rocks on the Isle of Tiree in the Inner Hebrides last year. A member of the only pod found in British waters, she died after getting entangled in fishing lines.

It was a sad discovery, especially as a postmortem revealed Lulu had never had a calf. But a recent autopsy also revealed something else that is alarming marine experts and offers a bleak, damning judgment on the state of Britain’s coastal waters. Lulu’s body had some of the highest levels of a particular type of manmade chemical ever recorded – more than 100 times above the level that scientists say will have biological consequences for a species.
