MDBA legally obliged to place the health of Murray Darling above all else

When Fair Water Use contacted Mr Mike Taylor, Chairman of the Murray-Darling Basin Authority he confirmed that the MDBA is legally obliged to place the health of the river system ahead of all other considerations. Accordingly, Fair Water Use urged the authority to do all that it could to use the inundations that have blessed much of its northern headwaters to breathe life back into our dying river system and not allow this opportunity be squandered to serve narrow vested commercial interests.

Kalahari Fires: reflections on man's first tool of environmental management

Helga Vierich writes that Fire has long played a part in the ecology of the Kalahari Desert of Southern Africa. Among the Kua of the south-central Kalahari the power of natural and man-made fires is well understood. These hunter-gatherers use fire to control ticks, increase plant fruit yields, alter the species composition of wild plant communities, influence the movement of game, and to attract specific animals into snares and traps.

Deforestation drys continents - new theory explains how

Whilst many people have been aware (but have mostly been ignored) that vegetation, especially forests, creates rain, and whilst desertification has been linked to deforestation historically many times, there is a new and robust theory to explain how this may happen.

Book Review: Peter Andrews - Back from the brink - agriculture for Australians

This book paints a picture of the ecological mechanics of this continent, using clear, concise prose. It is a painlessly educative book. The bold claim of its subtitle, "How Australia's landscape can be saved," stands up to scrutiny.

Take a new look at thistles, dock plants and other hardy weeds. Enjoy trialling the author's theories in your neglected front garden or replot your broadacre farm. Re-examine the cause of total re-nativisation in the light of galloping desertification. Peter maintains that his simple hydrological theory holds true for the entire continent. He re-interprets the history of this land; he may well be right.
