The extreme temporal and spatial variability of Australia's rainfall affects the quantity and quality of water resources, the productivity of agricultural systems, and aquatic and terrestrial ecosystems. Given the impact of extreme events such as floods and the massive investment in water-related infrastructure, evaluation of these risks is an issue of national economic and environmental significance. Monte Carlo simulation techniques will quantify the risks associated with current and future climate change, and the combined risks that come from multiple sources, such as from coastal tides and storm runoff. This research will provide a new spatial framework for calculating risk as well as tools to evaluate flood risk.Read moreRead less
Using ancient DNA to understand Australia's past and manage its future. The aim of this program is to establish an ancient DNA research centre for Australia, and use long-term natural records to investigate the genetic responses of animals, plants, and micro-organisms to environmental change. By examining biological processes before, during, and after major changes (eg coral bleaching, salination) the evolution and selective pressures at important genetic loci will be identified, and related to ....Using ancient DNA to understand Australia's past and manage its future. The aim of this program is to establish an ancient DNA research centre for Australia, and use long-term natural records to investigate the genetic responses of animals, plants, and micro-organisms to environmental change. By examining biological processes before, during, and after major changes (eg coral bleaching, salination) the evolution and selective pressures at important genetic loci will be identified, and related to environmental change to enhance effected planning and future management of Australia's ecosystems, biodiversity and tourism. Key records will come from lake-beds, billabongs, coral reefs, rodent nests, megafaunal bones, and ancient human material.Read moreRead less

Summary
High resolution airborne radar for environmental research: soil moisture, vegetation, salinity and terrain mapping. There is a rapidly increasing demand for a range of environmental data. For example, information on soil moisture status is required for efficient and sustainable water use. Moreover, irrigation practices and large scale clearing have led to serious land degradation through increased salinity from rising water tables. Combined soil moisture and salinity measurement will provide im ....High resolution airborne radar for environmental research: soil moisture, vegetation, salinity and terrain mapping. There is a rapidly increasing demand for a range of environmental data. For example, information on soil moisture status is required for efficient and sustainable water use. Moreover, irrigation practices and large scale clearing have led to serious land degradation through increased salinity from rising water tables. Combined soil moisture and salinity measurement will provide important insight to this complex issue. Further, understanding the complex and rich biodiversity of Australian flora and its adaptation to droughts and fire is essential to ensuring Australian ecosystem longevity. Knowledge of flora changes through time as a function of soil moisture content and salinity is key to gaining this understanding.Read moreRead less

There is growing international and national concern over the possible environmental, economic and social impacts of global and regional climate change. This project brings together a multi-disciplinary team of internationally recognised research leaders and the resources they command to investigate the environmental impacts of climatic changes in the Nile basin over geologically recent times. The outcome will be a more comprehensive understanding of how a major river system responds to global and regional climate change, and will provide an enhanced conceptual basis for anticipating how drainage systems such as the Murray-Darling could respond to future change.Read moreRead less
Environmental change in northern Cenozoic Australia: a multidisciplinary approach. The Intergovernmental Panel on Climate Change (IPCC) warned that by 2020 to 2050, Australia will suffer significant biodiversity loss and water shortages. Our research will document and date the evolution of Australia's biota through three cycles of climate change over the last 25 million years to quantify and thereby better anticipate the nature and dimension of threats facing our natural and cultural communities ....Environmental change in northern Cenozoic Australia: a multidisciplinary approach. The Intergovernmental Panel on Climate Change (IPCC) warned that by 2020 to 2050, Australia will suffer significant biodiversity loss and water shortages. Our research will document and date the evolution of Australia's biota through three cycles of climate change over the last 25 million years to quantify and thereby better anticipate the nature and dimension of threats facing our natural and cultural communities. We will develop innovative techniques to date prehistoric biotic and climatic events and, using a range of tracers, characterize ancient environments and groundwater. This project will assist rural and regional Australia through education and job creation in geotourism and natural resource interpretation and provide a mechanism to combat generational skill shortage.Read moreRead less

There is widespread concern among scientists, farmers and policy makers over the possible environmental, economic and social impacts of global warming. Certain greenhouse gases such as carbon dioxide contribute to such warming, but other gases and dust particles, especially those from volcanic eruptions, may trigger global cooling. This project will evaluate the impact of a major prehistoric eruption on global climate and regional plant, animal and human communities. We know that future eruptions will occur, so it is important to clarify the climatic and other effects of past eruptions. The project will also enhance our understanding of prehistoric cultural changes and extinctions.Read moreRead less
