Learning Dust Lesson to Fight Wildfires

By

untitledIT is generally agreed that the worst dust storms since European settlement were during the 1944-1945 period.  

In his book Out of the West: A Historical Perspective of the Western Division of NSW, former Western Lands Commissioner, Dick Condon, says there were 34 severe dust storms at Wagga Wagga during the period 1944-45, many so bad that it would have been necessary to turn the lights on in order to see inside the average sized house.  

Mr Condon suggests the dust storms during the 1982-83 drought were not as bad as those during the period 1885 to 1945 because of the much improved conditions of the landscape in the semi-arid and arid grazing country in western New South Wales.

In contrast, it is generally agreed that bushfires are getting worse.   [Read more…] about Learning Dust Lesson to Fight Wildfires

More on Californian Bushfires

“I moved from San Francisco to the LA area about a month ago so am experiencing the fires from a little closer vicinity. The local news
told us that the areas on fire last burnt about 1929! The brush is 20ft high in many places! After a week of burning they finally pulled
in the larger drop aircraft including the DC-10.” Vernon.

Los Angeles: The so-called Station Fire more than doubled in size as it burned out of control for a sixth day, charring 105,000 acres (42,500 hectares), up from 42,000 acres (17,000 hectares) late on Sunday, and sending up towering plumes of smoke that fouled the air for miles (km) around.  Read more here.

Warnings about Bushfire Warnings: A Note from Roger Underwood

By

AWSOME_topA PERSISTENT complaint from victims of the Black Saturday bushfires in Victoria was that they had “received no warning”. Over and again we heard statements like this: “There was no fire anywhere, but the next thing, we had fire all around us. There was no word of warning, and we never stood a chance”.

This issue has since been highlighted by the Royal Commission in its Interim Report, and is being taken to heart by fire authorities all over Australia. In Western Australia, for example, the Fire and Emergency Service (FESA) has rolled out a new warning arrangement based on mobile phones, and has carried out a substantial and well-publicised test in a Perth Hills suburb. It was said (by FESA) to have been a great success.

This is a delicate subject, because I don’t want to sound disrespectful to people who lost their lives or suffered in the Victorian fires. I realise that many people are perplexed by the way they were engulfed by fire and caught by surprise. I understand the desire of authorities to get warning systems in place. Officials realise that a failure to deal with this issue in future fires will come back to haunt them if complaints are made to Royal Commissions, Coronial inquiries and the media.

However, the downsides, weaknesses and dangers in bushfire warning systems must be properly understood.  [Read more…] about Warnings about Bushfire Warnings: A Note from Roger Underwood

Carbon Credits for Prescribed Burning: A Note from Green Davey

By

 THE Tiwi Islands (Bathurst and Melville) are off the north coast of Australia. They are mostly covered with grassy savanna, much like that in parts of southern Africa. In Africa, this savanna is the result of thousands of years of burning by humans.

If burning is interrupted, then woody shrubs thrive, and the savanna turns into thickets. Due to lightning, fires will still occur, but they will be at longer intervals, and much fiercer, potentially lethal to both humans and wildlife, as in Kruger National Park (http://ag.arizona.edu/oals/ALN/aln54/govender.html ).

I have never been to the Tiwis, but I suspect that they are very similar in this respect to Africa, or Madagascar, where Dr Kristian Kull (Isle of Fire 2006) has eloquently described the political ecology of regular burning by humans.

My attention was caught recently by a television news item about the ‘Tiwi Carbon Project’, in which CSIRO is working with the Tiwi islanders to reduce the carbon released by their fires, and so win them large amounts of cash as ‘carbon credits’. I pursued this back in time, and found a few events which may relate. In 2006, the ABC’s Catalyst program carried a story about a similar scheme in the Northern Territory. The then Northern Territory Environment Minister, Marion Scrymgour (a Tiwi woman), seemed to be working with several Aboriginal Elders, and Dr Jeremy Russell-Smith, a scientist at the CRC Tropical Savannas Management, to promote mild traditional burning, early in the season, to avoid fierce fires later on – wonderful.  [Read more…] about Carbon Credits for Prescribed Burning: A Note from Green Davey

Defining the Greens (Part 16) and Bushfires

By

canberra 2003 croppedIN 1994, Ray Evans bought a cottage at Marysville (Victoria, Australia) which he and his wife subsequently renovated and extended.   The cottage and its extensive garden were destroyed by fire on the night of Saturday February 7 – now known as Black Saturday.    In the following provocative and political article Mr Evans blames the fire “on green doctrine” and the Victorian government wilfully ignoring the advice of a previous inquiry because it did not want to “offend the sensitivities of the Greens”.
