Maximising the conservation of biodiversity and the delivery of ecosystem services: What to do, where and when. The economic wealth of Australia is underpinned by its remarkable biological diversity. However, land and water degradation are eroding Australia's natural asset base damaging industries such as tourism, fisheries, and forestry. Given limited funds for biodiversity conservation, we need to minimise the misallocation of resources by making wise investments. This research will result in ....Maximising the conservation of biodiversity and the delivery of ecosystem services: What to do, where and when. The economic wealth of Australia is underpinned by its remarkable biological diversity. However, land and water degradation are eroding Australia's natural asset base damaging industries such as tourism, fisheries, and forestry. Given limited funds for biodiversity conservation, we need to minimise the misallocation of resources by making wise investments. This research will result in frameworks and tools to ensure that we maximise the protection of biological diversity and the delivery of ecosystem services (such as clean water) that are important for human well-being. We will share the results of our research with decision makers, scientists, and the general public.Read moreRead less
Economics of Conserving Australian Tropical Wildlife: An Analysis of the Role of Economic Valuation, Property Rights and Commercialisation. Australian tropical native animals are selected to analyse economic valuation (use and non-use valuation) of wildlife species and to assess systematically the role of property rights and commercialisation in conservation. The project will (1) reduce bias of Australian economic studies in favour of temperate species; (2) answer several unresolved questions ra ....Economics of Conserving Australian Tropical Wildlife: An Analysis of the Role of Economic Valuation, Property Rights and Commercialisation. Australian tropical native animals are selected to analyse economic valuation (use and non-use valuation) of wildlife species and to assess systematically the role of property rights and commercialisation in conservation. The project will (1) reduce bias of Australian economic studies in favour of temperate species; (2) answer several unresolved questions raised in the Parlimentary Report on Commercial Utilisation of Australian Wildlife; (3) advance economic theory (e.g. relating to dynamic influences on economic valuation) and provide new insights into property rights making use of empirical and experimental results, and (4) thereby contribute to public policy decision-making.Read moreRead less
Quantifying the El Niño-Indian Ocean Dipole system using high-resolution coral palaeoclimate archives. The ocean surrounding Indonesia is the warmest on Earth and a major source of energy for global atmospheric circulation. Understanding the role of the Warm Pool in future climate change is of key importance, but highly controversial because the potential extent of its variability is largely unknown. To address this issue, this project will provide the first major geochemical investigation of ....Quantifying the El Niño-Indian Ocean Dipole system using high-resolution coral palaeoclimate archives. The ocean surrounding Indonesia is the warmest on Earth and a major source of energy for global atmospheric circulation. Understanding the role of the Warm Pool in future climate change is of key importance, but highly controversial because the potential extent of its variability is largely unknown. To address this issue, this project will provide the first major geochemical investigation of recently discovered ancient corals in Indonesia using state-of-the-art microanalytical techniques. Outcomes from these palaeoclimate records will advance our understanding of global climate change, rainfall variability related to the El Nino - Indian Ocean Dipole system, and Australian drought.Read moreRead less
Designing for uncertainty in conservation auctions. Economic theory and case study evidence show that tenders or auctions are more efficient than grant mechanisms for encouraging landholders to produce environmental outcomes on private land. These studies have ignored the effects of uncertainty of both bidders and administrators about factors such as landholder participation and the level of environmental benefits that will be delivered. This project will test whether distributing environmental ....Designing for uncertainty in conservation auctions. Economic theory and case study evidence show that tenders or auctions are more efficient than grant mechanisms for encouraging landholders to produce environmental outcomes on private land. These studies have ignored the effects of uncertainty of both bidders and administrators about factors such as landholder participation and the level of environmental benefits that will be delivered. This project will test whether distributing environmental funds via tenders is still efficient when uncertainty about various important factors is considered. Results from this research are expected to inform the cost effective design of systems to pay landholders for the provision of environmental benefits even when there is high uncertainty.Read moreRead less
Benefits and costs of non-market valuation for environmental management. Benefits from environmental policies are often unpriced “non-market values” (NMVs). Environmental agencies struggle to know how best to measure these relatively intangible benefits, but doing so is important to ensure value for money from public investments. Environmental economists have developed and applied a wide range of methods for estimating NMVs. The methods vary in their comprehensiveness, accuracy and cost. Yet no ....Benefits and costs of non-market valuation for environmental management. Benefits from environmental policies are often unpriced “non-market values” (NMVs). Environmental agencies struggle to know how best to measure these relatively intangible benefits, but doing so is important to ensure value for money from public investments. Environmental economists have developed and applied a wide range of methods for estimating NMVs. The methods vary in their comprehensiveness, accuracy and cost. Yet no rigorous tool is available to assess (a) which NMV method is best to implement, accounting for its cost and its potential to improve decisions, or (b) whether any NMV method improves decisions enough to warrant its cost. In creating such a tool, this project will deliver a key breakthrough in environmental economics.Read moreRead less
Nitrogen characteristics of plant communities along the North Australian Tropical Transect (NATT). It has become evident that biosphere processes need to be addressed at a global scale to understand global changes. Continental transects analyse ecosystem processes in a global context. The North Australian Tropical Transect (Darwin to Tennant Creek) represents 25% of Australia's vegetation. Biogeological research is underway on NATT ecosystems.

It has become evident that biosphere processes need to be addressed at a global scale to understand global changes. Continental transects analyse ecosystem processes in a global context. The North Australian Tropical Transect (Darwin to Tennant Creek) represents 25% of Australia's vegetation. Biogeological research is underway on NATT ecosystems. Nitrogen availability strongly affects ecosystem productivity, and is of major interest as nitrogen pollution threatens the biosphere. In Australia, nitrogen levels are generally low, but overall knowledge is limited. An integrated ecophysiological approach will relate soil and plant nitrogen characteristics, and provide an analysis of nitrogen relations along NATT. Results will be linked to existing NATT and international transect research.Read moreRead less
The Indian Ocean Dipole, Australasian drought, and the great-earthquake cycle: Long-term perspectives for improved prediction. The protracted drought across Australia and Boxing Day 2004 earthquake in Sumatra defied prediction, and are causing incalculable environmental, economic, and social harm. Knowledge of past climate extremes will enhance our ability to predict climate change, and alleviate adverse affects for Australasian nations who miss-out in the future redistribution of life-giving mo ....The Indian Ocean Dipole, Australasian drought, and the great-earthquake cycle: Long-term perspectives for improved prediction. The protracted drought across Australia and Boxing Day 2004 earthquake in Sumatra defied prediction, and are causing incalculable environmental, economic, and social harm. Knowledge of past climate extremes will enhance our ability to predict climate change, and alleviate adverse affects for Australasian nations who miss-out in the future redistribution of life-giving moisture. Insights into the great-earthquake cycle will help fulfil Australia's responsibility to predict tsunamis, for the benefit of nations fringing Australasian seismotectonic zones. Development of improved techniques in palaeoclimatology, palaeoclimate modelling, and palaeoseismology will provide new collaborations and opportunities for research, training, and education.Read moreRead less
Formation, degradation and migration of a yet unidentified POP source. Australia has recently ratified the Stockholm Convention, targeting persistent organic pollutants (POPs) for global reduction and elimination. A significant gap exists, however, in understanding sources and pathways of POPs in Australia, and subtropical/tropical environments. Previous research has shown an extensive POP contamination in coastal Australia, and exposure of biota to elevated levels.

Australia has recently ratified the Stockholm Convention, targeting persistent organic pollutants (POPs) for global reduction and elimination. A significant gap exists, however, in understanding sources and pathways of POPs in Australia, and subtropical/tropical environments. Previous research has shown an extensive POP contamination in coastal Australia, and exposure of biota to elevated levels. The present study will evaluate the formation, degradation and migration of POPs, and their significance to Australia's past, present and future emissions. The outcomes will allow identification of sources, their prioritization for elimination and exposure prevention, and ultimately serve to protect the environment and human health in Australia.Read moreRead less
A novel approach to tracking estuarine food chains: combined use of fatty acid and stable isotope biomarkers. Fatty acid biomarkers provide promising novel tracers for studying estuarine food chains. Stable isotopes, commonly employed in food chain studies, lack specificity to allow easy determination of feeding relationships. Different primary producers are characterised by unique fatty acid sequences. This study will thoroughly evaluate the applicability of fatty acid biomarkers in tracking ....A novel approach to tracking estuarine food chains: combined use of fatty acid and stable isotope biomarkers. Fatty acid biomarkers provide promising novel tracers for studying estuarine food chains. Stable isotopes, commonly employed in food chain studies, lack specificity to allow easy determination of feeding relationships. Different primary producers are characterised by unique fatty acid sequences. This study will thoroughly evaluate the applicability of fatty acid biomarkers in tracking both natural and human-impacted estuarine food chains. By developing a new approach of combining the advantages of fatty acid bioamrkers and stable isotopes in studying estuarine trophodynamics, this study will provide essential information for the management of estuarine biotic resources.Read moreRead less
