Burke’s Backyard Infested with Native Invasive Scrub: Media Release from Community Group

November 16, 2006 By jennifer

The following media release was distributed by a group called the NSW Regional Community Survival
Group
* after TV personality Don Burke was interviewed by radio personality Alan Jones in Sydney yesterday:

“Australia’s pioneer lifestyle presenter and Chair of the Australian Environment Foundation, Don Burke, has called upon the Iemma Government to make further changes to native vegetation laws so that farmers in western NSW can control infestations of invasive scrub.

“Premier Iemma must act fast to stop the destructive invasion of native scrub before it is too late for the environment
and farmland of western NSW,” said Don.

“Recent changes to native vegetation regulations announced by the NSW Government are a step in the right direction, but they still don’t provide farmers with enough flexibility to rehabilitate land degraded by invasive scrub.
“Hundreds of farming families will be forced off their land if this problem is not fixed: who then will be left to care for the environment of western NSW?” Don said.

Invasive scrub (also called woody weeds) are native shrubs that have increased greatly in density over the last 130 years, invading the formerly open grassy woodlands of western NSW from the Queensland border to the Riverina in southern NSW.

Scrub infestations now cover up to 12 million hectares of western NSW – an area twice the size of Tasmania – with another 6 million hectares vulnerable to invasion when the drought breaks. It is estimated that up to 1,000 farms are fighting the problem.

“I was invited by farmers from Nyngan and Cobar to view first-hand the destructive impacts of invasive scrub on the landscape of western NSW. What I saw was not a natural feature of the environment.

“I was shocked to see how near ‘monocultures’ of scrub had out-competed native grasses for moisture and nutrients, leaving the soil prone to severe wind and water erosion.

“Vast tracts of land are now an ecological desert, exacerbating current drought conditions,” said Don.

Don said that for thousands of years, Aboriginals used fire to suppress outbreaks of scrub.

“Original infestations of scrub can be traced to a lack of bushfires after the land was first settled and coincided with periods of above average rainfall in the 1860s and 1870s. High rainfall seasons in the 1950s, 70s, 80s and 1990s resulted in further outbreaks. Overgrazing in the distant past – including by rabbits – also contributed to the invasion of scrub,” explained Don.

“With the introduction of tighter land clearing laws in 1996, farmers in western NSW have been ‘straight jacketed’ ever since in their efforts to stop the insidious spread of native scrub. With native grasses virtually obliterated in the last ten years, the country will no longer carry a fire, so it can’t naturally thin dense areas of scrub.

“Clearing and short term cropping are now the only effective tools to remove scrub and suppress regrowth, giving
native grasses a chance to rejuvenate,” said Don.

“Farmers want to restore the landscape to its natural state of open woodlands and grasslands, but political pressure from radical greens has put a bureaucratic handbrake on land restoration.

“In return, farmers are prepared to set aside a minimum of 15 per cent of their land for the preservation of native
woodlands. Combined with rehabilitated native grasslands, this will lead to an average cover of 50 to 60 per cent of
native vegetation on farms in western NSW.

“After making statements about the vital role that farmers play in protecting the environment, I’m calling on moderate
green groups such as the Australian Conservation Foundation to support farming families in their efforts to rehabilitate the degraded landscape of western NSW,” ended Don.

* The NSW Regional Community Survival Group was established about a year ago to draw attention to the problem of invasive woody weeds in western NSW. Some of the groups members were interview by the Sunday Program as part of its feature on ‘The Great Land Clearing Myth’.

A Rare Rainforest Rhinoceros

November 14, 2006 By jennifer

Rhinoceros are usually associated with the African savannah, but interestingly there are species which also occur in rainforests in Indonesia. The one-horned Java Rhino and the two-horned Sumatran Rhino are the rarest rhinos on earth.

Here’s a picture of a rainforest rhinoceros from one of the many camera traps Richard Ness has had set:

There are only a few hundred Java and Sumatran rhinos remaining in the wild.

Interestingly in Africa, white rhino numbers increased from about 200 individuals in 1904 to over 11,000 in 2004 thanks to conservation programs. In contrast, black rhino numbers dropped from perhaps 60,000 sometime before 1970 to may be 15,000 in 2004 no thanks to poaching.

Net Increase in Forest Cover Globally

November 14, 2006 By jennifer

For years, environmentalists have been raising the alarm about deforestation. But even as forests continue to shrink in some nations, others grow — and new research suggests the planet may now be nearing the transition to a greater sum of forests.

A new formula to measure forest cover, developed by researchers at The Rockefeller University and the University of Helsinki, in collaboration with scientists in China, Scotland and the U.S., suggests that an increasing number of countries and regions are transitioning from deforestation to afforestation, raising hopes for a turning point for the world as a whole. The novel approach, published this week in the online edition of Proceedings of the National Academy of Sciences, looks beyond simply how much of a nation’s area is covered by trees and considers the volume of timber, biomass and captured carbon within the area. It produces an encouraging picture of Earth’s forest situation and may change the way governments size up their woodland resources in the future.

Australian PM Rolls Over On Carbon Trading

November 14, 2006 By jennifer

Last night Australia’s Prime Minister, John Howard, announced an inquiry into a possible carbon trading scheme for Australia. He was speaking at the Business Council of Australia Annual Dinner in Sydney and the Ambassadors of both the United States and Indonesia were present. Towards the end of his speech, which was very much about Australia’s economic outlook, he said:

“I do want to say something about the related issues of climate change and energy security. And I very deliberately link the two of them because you can’t think of the reaction of relevant countries to climate change without understanding the importance to them of energy security. And some of the heightened concern about climate change issues in recent months – indeed in recent years – are very directly related to energy security. And we need to understand some fundamentals about the two of them, put bluntly, there is no way that a country is going to embrace climate change measures or responses to the growth of greenhouse gas emissions, which in anyway imperial the energy security of that country. And this is particularly so of countries such as China and India, countries which are for the first time in four or five hundred years reclaiming, particularly in the case of china, reclaiming their position in the world economy, enjoying extraordinarily rapid economic growth – economic growth which is very largely fuelled and supported and facilitated by cheap suppliers of energy from countries such as Australia, but also from their own and from other sources – and to expect a country like china to embrace change in relation to the climate, which in some way imperials the energy security, just at a time when it is beginning to enjoy the fruits of economic growth and remarkable rates of economic growth, is to expect the unachievable and the unrealistic.

I think it is important to keep the challenge of climate change in perspective. I share your President’s view that it is happening and although I have been accused and continue to be accused of being somewhat of sceptic on the issue, the truth is I’m not that sceptical, I think the weight of scientific evidence suggests that there are significant and damaging growths in the levels of greenhouse gas emissions and that unless we lay the foundation over the years immediately ahead of us to deal with the problem, future generations will face significant penalties and will have cause to criticise our failure to do something substantial in response.

The debate of course is about the intensity and the pace of the damage being done by climate change and there will continue to be very intense debate about that. We’ve made it very clear that we won’t ratify the Kyoto agreement – we took that decision some years ago because we feared that ratifying that agreement in the form in which it then and still largely exists, could have damaged the comparative advantage this country enjoyed as a result of our abundance of fossil fuels and the importance of that abundance to Australia’s export and general performance – and nothing has happened to alter that fact. In the meantime, however, we have committed ourselves to achieve the target of 108 that was given to us at the Kyoto meeting in 1997 and we are on track to achieve, or as near as dam it, achieve that outcome within the time stipulated.

I think it’s very obvious, both from what Michael Chanay said, and from what others have said in recent weeks, that we do need to find, call it what you may, a new Kyoto. We do need, as a world community, to try and find a new global solution and that global solution must include all of the major emitters. And we have to understand some of the fundamentals that drove the original Kyoto. The original Kyoto was largely fashioned, I don’t say this critically, I hope I say it objectively, it was largely fashioned to accommodate the environmental goals and position of European countries. It was built with not sufficient regard to the position of a country such as Australia, a highly developed country which was a net exporter of energy, and therefore I think the formation of AP6, which includes in aggregate, almost 50 per cent of the world’s emitters, also close to 50 per cent of the world’s population and also close to 50 per cent of the world’s GDP, that particular grouping can provide an extremely sure foundation for the development of a new international covenant or new international understanding on this issue.

It is imperative from our point of view that as we look at such issues as an emissions trading system that we fashion here in Australia, and see fashioned globally, a trading system that protects the natural advantages that this country has. This country does have enormous natural advantages of our resource industries, not only coal and gas, but importantly uranium as well. And let me say that, something I’ve said on a number of occasion in recent weeks, and that is that there is no one single solution to the global challenge. We need to maintain the profitability that our great abundance of fossil fuels has given us, we need to accelerate the development of clean coal technologies, and the like, that were identified two and a half years ago in the Energy White Paper, we need to recognise that at the purifier, but not as a contributor to base power load generation, renewables, such as solar and wind can make a valuable contribution and we also need to recognise the capacity, particularly as we develop clean coal technologies with the inevitable consequences they have for pricing, we need to examine and keep on the table the nuclear option. It is some years off but in a couple of weeks time Dr Ziggy Switkowski ’s committee will report and it, will I hope make available in a very objective fashion, the analysis of nuclear power, both in terms of safety availability, supply and the economic of it in the whole climate change equation.

I’ve indicated in the past that I do not intend to preside over policy changes in this area that are going to rob Australia of her competitive advantage in the industries that are so important to us and I repeat that commitment tonight. I do welcome the contribution that the Business Council has made and many other people in the business community have made to tackling this issue. Many of you will know that over the past few weeks the Government has reiterated its broad approach and later this week I will meet some significant business figures, some of them are in the room tonight, who are involved in the resource sector to discuss aspects of the Government’s response to the climate change challenge.

I want to indicate to you tonight that the Government will establish a joint government business task group to examine in some detail the form that an emissions trading system, both here in Australia and globally, might take in the years ahead. I think it is important to involve the business community in an analysis of this issue because decisions taken by the Government in this area will have lasting ramifications for Australia’s business community. I think we all recognise that we have to examine in the time ahead how we might devise an emissions trading system which properly cares for and accommodates the legitimate interests, and therefore maintains, the competitive advantage that this country enjoys in the industries that are familiar to you.

We do not want a new Kyoto that damages Australia. We need a new Kyoto that includes Australia but includes Australia on a basis which is appropriate to our interests and our needs. So therefore I indicate to you tonight that we will be establishing, in discussion with the Business Council of Australia and other business groups and individual business leaders, a joint government business task group that will examine, against the background of our clearly identified national interests and priorities, what form an emissions trading system, both here in Australia and globally, might take to make a lasting contribution to a response to the greenhouse gas challenge, but in a way that does not do disproportionate or unfair damage to the Australian economy and the industries which have been so enormously important to the generation of our wealth and the development of our living standards over the last 10 or 20 years.”

The annoucement would have caught many commentators by surprise. Indeed just yesterday the Australian media was reporting a possible rift between the PM and his Treasurer, Peter Costello, on climate change because over the weekend the Treasurer had publicly endorsed the idea of a carbon trading scheme for Australia post Kyoto, from 2012. No doubt he knew the PM would announce the same, officially, last night.

Its all good timing with Ian Campbell, Australia’s Environment Minister, over in Nairobi at the United Nation’s Climate Conference. The government appears to be branding its new approach to climate change the ‘new Kyoto’.

According to ABC Online:

“The president of BP Australia and member of the Business Roundtable on Climate Change, Gerry Hueston, has told Radio National Breakfast it is a welcome initiative.

“It’s important now that the big emitters like the US and China and potentially India come on board because their involvement is the thing that’s going to actually make the big difference,” he said.

The executive director of the Australian Conservation Foundation, Don Henry, has also welcomed the announcement.

He says the Government should now set a target for reductions in carbon pollution.

“The crucial thing in any emissions trading scheme is first and foremost what cap, what reductions in greenhouse gas emissions you’re going to require,” he said.”

In a recent column for The Land (26th October) I wrote that there is a place for government policies which promote carbon sequestration with particular reference to logging trees, woodland thickening and also biochar:

“Actively growing trees sequest carbon dioxide and harvesting this timber moves the stored carbon from the forest to the wooden product, be it a railway sleeper or bridge girder.

Rates of carbon sequestration slow as forests age with old growth forests storing but not sequesting carbon.

But environmental activists don’t much like the idea of actively managing forests as this involves cutting down trees.

So we end up using materials like concrete, steel and aluminum whose production involves lots of energy – and lots of carbon dioxide emissions.

Indeed, early this year, the Federal Government supported the Australian Rail Track Corporation’s decision to no-longer use timber railway sleepers.

In the future, the 400,000 railway sleepers it buys each year will be concrete, which according to Mark Poynter from the Institute of Foresters of Australia this will result in an extra 190,000 tonnes of carbon dioxide emissions each year.

At the recent Australian Environment Foundation conference, Mr Poynter put this in perspective by explaining that while the Victorian government has promoted wind farms as part of its renewable energy strategy (estimated to be saving 250,000 tonnes of greenhouse gas emissions per year), about 75 percent of this saving has, in effect, been negated by the decision to use concrete rather than wooden railway sleepers.

While every bit perhaps makes a difference, the really large carbon savings are in our rangelands.

Well known ecologist, Dr Bill Burrows, has calculated that grazed woodlands in Queensland alone sequest about 35 million tonnes of carbon dioxide each year.

Indeed if woodland thickening was including in Australia’s official Greenhouse Inventory we might not need any more wind farms.

Incredibly, because of the way the Kyoto Protocol is framed, Australia’s national carbon accounting system counts savings from the banning of broad-scale tree clearing, but not carbon savings from regrowth or woodland thickening in western NSW and Queensland.

What about counting the carbon in woody weeds converted into biochar – a charcoal with soil ameliorant properties – created through the type of low temperature patchy burns once practiced by Aborigines?

It is perhaps time for environmental activists as well as state and federal governments to open both eyes when it comes to global warming and start accurately considering all the opportunities and costs of carbon sequestration in our forests and rangelands.”

It’s certainly time for the bureaucrats to start consider all the big mechanisms for carbon sequestration, if the PM has really rolled over on the idea of a carbon trading scheme.

Golden Rice is Cost Effective: A Note from David Tribe

November 14, 2006 By jennifer

Hi Jennifer,

Vitamin A deficiency (VAD) afflicts many people around the world, especially in developing countries. Some of the adverse health outcomes of VAD include increased mortality, night blindness, corneal scars, blindness and measles among children, as well as night blindness among pregnant and lactating women. In a bid to reduce VAD-related diseases, rice plants were engineered to produce higher levels of beta-carotene in the endosperms or grains, and the result of this effort is Golden Rice 2. In an article in Nature Biotechnology, Alexander Stein and colleagues from the University of Hohenheim, Germany and Sitaram Bhartia Institute of Science & Research, India, presented a new methodology for assessing the potential impact and cost-effectiveness of Golden Rice 2 in India.

Democrats Set to Change US Climate Change Policy

November 12, 2006 By jennifer

With the Democrats winning control of both the Senate and House of Representatives in the recent US elections, Senator Barbara Boxer will take over as chairman of the US Senate Environmental Public Works Committee and has pledged to introduce legislation to curb greenhouse gases. The legislation is likely to be modeled after a new California law that seeks to cut California’s emissions by 25 percent, dropping them to 1990 levels by 2020. Read the article at MSNBC by clicking here.

So the Democrats aren’t talking about signing Kyoto? Why not?
