Complexity in climate impact assessment: a methodology to address extremes. It is something of a truism that the events and states of the changing environment that affect society tend to fall in the extremes. My goal is to develop a model-based methodology to characterize the extremes that are not usually predicted by climate models. Key extremes of importance to stakeholders in Australia and around the world include coastal flooding and fire. These events, in the context of regional climate var ....Complexity in climate impact assessment: a methodology to address extremes. It is something of a truism that the events and states of the changing environment that affect society tend to fall in the extremes. My goal is to develop a model-based methodology to characterize the extremes that are not usually predicted by climate models. Key extremes of importance to stakeholders in Australia and around the world include coastal flooding and fire. These events, in the context of regional climate variation, will act as test cases for the methodology. From this work, the likelihood of policy-relevant events in the future can be evaluated, with a robust assessment of the uncertainty.Read moreRead less
New methods assisting the detection and attribution of changes in atmospheric carbon dioxide (CO2) levels. New scientific tools to manage the global environment are an international priority. An Australian breakthrough in technology has the potential to revolutionise the measurement and management of atmospheric carbon dioxide, the single largest anthropogenic contributor to greenhouse warming. The fellowship levers sufficient resources to assess this potential in a number of critical applicatio ....New methods assisting the detection and attribution of changes in atmospheric carbon dioxide (CO2) levels. New scientific tools to manage the global environment are an international priority. An Australian breakthrough in technology has the potential to revolutionise the measurement and management of atmospheric carbon dioxide, the single largest anthropogenic contributor to greenhouse warming. The fellowship levers sufficient resources to assess this potential in a number of critical applications, including: early detection of predicted increases in Southern Ocean carbon dioxide emission; indefinite low cost monitoring of regional carbon flux changes over continental Australia; improved international standards for CO2 measurement; and improved manufacturing components for use world-wide in trace-gas measurement.Read moreRead less
Integrating economics and science for land, water and biodiversity policy. Australian government programs for land and water conservation involve expenditure of billions of dollars, combined with much larger contributions from program participants. However, various problems with these programs have been identified. This research will assist program investors to better target funding, to employ more appropriate policy mechanisms, and to operate in a cost-effective way, achieving the most highly v ....Integrating economics and science for land, water and biodiversity policy. Australian government programs for land and water conservation involve expenditure of billions of dollars, combined with much larger contributions from program participants. However, various problems with these programs have been identified. This research will assist program investors to better target funding, to employ more appropriate policy mechanisms, and to operate in a cost-effective way, achieving the most highly valued environmental outcomes that can be achieved with the available budget. The project will develop improved theories, frameworks and economic models, integrating information from physical, biological and social sciences, and decision tools for use by environmental decision makers.Read moreRead less
Evaluating the adaptive potential of organisms to respond to environmental change. The program utilizes technological advances to develop a gene inventory for climatic change adaptation, using, as model system, the vinegar fly from divergent climates along eastern Australia. The inventory will result in new methods for monitoring climatic change impact on populations, and for testing adaptive potential of organisms from threatened habitats. A key hypothesis is that these organisms have restricte ....Evaluating the adaptive potential of organisms to respond to environmental change. The program utilizes technological advances to develop a gene inventory for climatic change adaptation, using, as model system, the vinegar fly from divergent climates along eastern Australia. The inventory will result in new methods for monitoring climatic change impact on populations, and for testing adaptive potential of organisms from threatened habitats. A key hypothesis is that these organisms have restricted genetic options to counter environmental change, increasing extinction risk. The program investigates genetic adaptation to pollutants in midges, a key group for monitoring water health. By assessing evolutionary potential and DNA species markers, biological signatures of aquatic pollutants should result.Read moreRead less
Science for resilience of coral reef systems. Hughes's Fellowship has enormous capacity to provide economic, cultural, environmental and social benefits for Australia. The coral reefs of Australia, particularly the Great Barrier Reef, Ningaloo Reef, and Lord Howe Island World Heritage Area are Australian national icons, of great economic, social, and aesthetic value to this country. Hughes and his collaborators in a newly-created ARC Centre of Excellence will be the premier providers of the scie ....Science for resilience of coral reef systems. Hughes's Fellowship has enormous capacity to provide economic, cultural, environmental and social benefits for Australia. The coral reefs of Australia, particularly the Great Barrier Reef, Ningaloo Reef, and Lord Howe Island World Heritage Area are Australian national icons, of great economic, social, and aesthetic value to this country. Hughes and his collaborators in a newly-created ARC Centre of Excellence will be the premier providers of the scientific expertise that underpins the management of Australian reefs, which is vital for the sustainable use of biodiversity goods and services (e.g. by the tourist industry, fisheries, and recreational users).Read moreRead less
