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

Wrong Policy on Population: A Note from Peter Ridd

By

LATEST statistics show that Australia’s population is growing at a rate of more than a million every three years. This growth rate is being driven primarily by record rates of immigration and a relative young population, itself a product of rapid past immigration. Doubtless Peter Costello’s baby bonus has also made the situation worse by encouraging the increased fertility rates of Australian women.

At the present rate Australia will have a population of about 50 million by mid century and 100 million by the end of the century. If this sounds implausible, consider that at the end of World War II, just 64 years ago, Australia’s population was only 7.5 million, i.e. it has almost tripled in that time.

This population growth should be considered an economic and environmental problem of huge proportions. From the economic point of view, Australia relies mostly on mining and agriculture for its export earnings. These industries require a very small proportion of the population to operate (although it is true that due to inadequate training in the technical trades and engineering, they have suffered a temporary labour shortages in recent years).

The growing population in Australia will not increase exports of iron ore, coal or gold and will reduce our exports of food as we are forced to consume more of our output internally. The money that comes to Australia from the sales of our resources presently gets divided among 22 million Australians. When the population doubles the amount per capita will halve.
