The Great Barrier Reef (GBR) is the largest contiguous coral reef ecosystem in the world81,49. That it is possibly the largest geomorphological structure ever created by living organisms is less widely appreciated. The GBR extends through approximately 15 degrees of latitude and more than 2100 km along the northeast Queensland coast, covering an area of 344,500 km282. It includes more than 2900 reefs of varying types (eg fringing, patch, cresentic, lagoonal, planar), dimensions and stage of growth, which together occupy greater than 20,000 km2, or about 5.8 percent of the total area of the GBR81,82 …

An agent-based simulation model has been developed with CORMAS combining simplified bio-physical processes of land cover, dry-land salinity changes, rainfall, farm profitability and farmer decisions on land uses in a dry-land agricultural catchment (no irrigation). Simulated farmers formulate individual decisions dealing with land use changes based on the combined performance of their past land cover productivity and market returns. The willingness to adapt to market drivers and the ability to maximize returns varies across farmers. In addition, farmers in the model can demonstrate various attitudes towards salinity mitigation as a consequence of experiencing and perceiving salinity on their farm, in …

It is well-understood that reductions in air quality play a significant role in both environmental and human health. Interactions between ozone depletion and global climate change will significantly alter atmospheric chemistry which, in turn, will cause changes in concentrations of natural and human-made gasses and aerosols. Models predict that tropospheric ozone near the surface will increase globally by up to 10 to 30 ppbv (33 to 100% increase) during the period 2000 to 2100. With the increase in the amount of the stratospheric ozone, increased transport from the stratosphere to the troposphere will result in different responses in polluted and …
