Human activities are causing Earth's sixth major extinction event-an accelerating decline of the world's stocks of biological diversity at rates 100 to 1,000 times pre-human levels. Historically, low-impact intrusion into species habitats arose from local demands for food, fuel and living space. However, in today's increasingly globalized economy,(More)
Australia is faced with large-scale dryland salinization problems, largely as a consequence of the clearing of native vegetation for cropland and grassland. We estimate the change in continental water vapour flow (evapotranspiration) of Australia during the past 200 years. During this period there has been a substantial decrease in woody vegetation and a(More)
Multivariate methods of classification and ordination were used to examine changes in plant composition over a three year period on a calcareous shrubby grassland grazed by rabbits and cattle in central Australia. In a site-time ordination of the data for all years, the season and amount of rainfall was the most important influence, followed by several soil(More)
The Australian Stocks and Flows Framework (ASFF) was developed to assess the biophysical longevity of the Australian economy, with top-down coverage of the whole physical economy based on bottom-up process-based detail. The ASFF employs mass-balance identities associated with stock and flow dynamics throughout the national economy and associated interaction(More)
Triple Bottom Line accounting is widely advanced as a way in which firms can realise broader societal objectives in addition to increasing shareholder value. In our analysis of the Australian economy, we integrate financial input-output tables that describe the inter-dependencies between economic sectors, with national social and environmental accounts to(More)
In an integrated analysis of an Australia with 20, 25 or 32 million people by the year 2050, six dilemmas emerged which link human population, labour, physical trade, material flows, greenhouse emissions and natural resource depletion. Each dilemma and the interactions between dilemmas are guided by many assumptions within the base case scenario, and the(More)
In the last 30 years the tussock grasslands of the eastern South Island, New Zealand, have been extensively invaded by species of Hieracium (hawkweeds), especially H. pilosella, H. praeltum, H. lepidulum and H. caespitosum (Scott, 1985). Hawkweeds were noted in tussock grasslands in the late 1800’s, but they began to increase dramatically in abundance in(More)
