What is sustainability when on the climate roller coaster?

This paper is about the identification of the changing world climate drivers and speculation concerning the future impact such drivers will have on countries in the southern hemisphere, especially Australia and New Zealand. A focus for the above is a case study of climate change which has induced severe hardships in the Bendigo region of Victoria, Australia. The authors are of the opinion this experience, in this extremely climate sensitive agricultural area, is a forerunner to what could occur to many regions in the southern hemisphere. The case study shows the vulnerability of communities to instruments of governance established during periods of stability and urges the urgent need for modified governance instruments during periods of rapid climatic change. The paper commences the discussion about the meaning, relevance and reality of sustainability for communities during times of climatic uncertainty. [ABSTRACT FROM AUTHOR]
