This project aims to understand how different animals encounter pesticide in the landscape through quantifying residue deposition in arid grasslands and investigating how pesticides used to control locust plagues affect fauna. This project will investigate fenitrothion and fipronil, the main pesticides used in Australia for locust control. It will develop a deposition model for aerial pesticide spraying, determine the short-term effect of sprayed pesticides on the behaviour and condition of free-ranging target fauna that use the environment differently, and quantify the relative importance of dietary and non-dietary exposure routes to gauge the importance of animal behaviour on pesticide exposure. Anticipated outcomes are improved baseline assessments for locusticides.Read moreRead less
The effect of aerial spraying of two pesticides on semi-arid grasslands. The project will investigate how two pesticides, fipronil and metarrhizium, used to control locusts, affect semi-arid ecosystems by examining impacts on invertebrates, their predators, lizards and soil processes. The effects will be followed through time in a large scale experiment to determine recovery and compare each pesticide.
Adapting for an uncertain future: farmer behaviour in water-stressed basins. Given the future risk of water scarcity, farmers will need to plan for greater farm-level adaptation. Drought and policy reform have inflicted significant economic, social and personal stress upon Murray-Darling Basin rural communities. This project aims to aid water managers and policy makers with a greater understanding of transformational farmer adaptation in order to plan for the economic, social and health impacts ....Adapting for an uncertain future: farmer behaviour in water-stressed basins. Given the future risk of water scarcity, farmers will need to plan for greater farm-level adaptation. Drought and policy reform have inflicted significant economic, social and personal stress upon Murray-Darling Basin rural communities. This project aims to aid water managers and policy makers with a greater understanding of transformational farmer adaptation in order to plan for the economic, social and health impacts of future water scarcity from climate change and water reform-related policies. The focus will be on the Murray-Darling Basin, as well as undertaking a comparative analysis with water stressed basins in the United States.Read moreRead less
Short- and long-term mitigation strategies for acid and metalliferous drainage control from iron ore mine wastes. Acid and metalliferous drainage from mine wastes, caused by oxidation of sulfide minerals, particularly pyrite, are a critical environmental issue worldwide. Although options to retard sulfide oxidation exist, including encapsulation methods, chemical additives and inhibition of iron-oxidising bacteria, these suffer from long-term instability. The project aims to investigate mechanis ....Short- and long-term mitigation strategies for acid and metalliferous drainage control from iron ore mine wastes. Acid and metalliferous drainage from mine wastes, caused by oxidation of sulfide minerals, particularly pyrite, are a critical environmental issue worldwide. Although options to retard sulfide oxidation exist, including encapsulation methods, chemical additives and inhibition of iron-oxidising bacteria, these suffer from long-term instability. The project aims to investigate mechanistic approaches, using readily available mineralogical materials, to provide passivating conditions resulting in slowed oxidation rates. The project’s focus is on treatments for wastes from iron ore deposits which are of high economic significance to Australia. The outcome aims to be a treatment ‘pathway’ enabling practical waste rock treatment over the acid forming time-profile.Read moreRead less
The role of engineered nanoparticles in the transport of environmental contaminants and the implications for remediation. Engineered nanoparticles are common in the environment due to their widespread industrial use. However, their influence on contaminant mobility is not known. This project will advance our understanding of the interactions of nanoparticles with environmental contaminants and thereby deliver safer and more sustainable remediation technologies.
Cross-cultural management of freshwater on resource-constrained islands. This project aims to develop a methodology for community-led adaptive water management on resource-constrained islands and will involve Indigenous communities in the development of predictive groundwater models. The project plans to apply three-dimensional participatory mapping, a stakeholder engagement process led and owned by the local communities, on Milingimbi Island in the Northern Territory. The extension of the parti ....Cross-cultural management of freshwater on resource-constrained islands. This project aims to develop a methodology for community-led adaptive water management on resource-constrained islands and will involve Indigenous communities in the development of predictive groundwater models. The project plans to apply three-dimensional participatory mapping, a stakeholder engagement process led and owned by the local communities, on Milingimbi Island in the Northern Territory. The extension of the participatory mapping with a subsurface component will then support the conceptualisation and development of a numerical model of the island's groundwater system. The predictive model and community engagement processes are expected to provide a more robust methodology for evaluating future water management plans. The project outcomes will contribute to solving water supply problems in remote communities in Australia, and overseas.Read moreRead less
