This project aims to produce the first of its kind online atlas that systematically documents the social, environmental and economic impacts in mining locations around the world. Analysing impacts at the source of metal supply chains is crucial to comprehend the implications of transitioning to metal-intensive low-carbon energy technologies. The project would deliver insights on available pathways to achieve a ‘just’ energy transition, meaning a transition that successfully tackles climate change without placing unacceptable burden on mining communities and environments. The goal of the research is to generate evidence-based recommendations so that future metal supply can be both reliable and responsible.Read moreRead less
Vulnerabilities for environmental water outcomes in a changing climate. This project aims to assess the vulnerability of freshwater ecosystems to extended droughts in a variable and changing climate. Governments around the world are investing in the restoration of regulated river systems with environmental water. However, the risks of climate change for environmental water management are seldom considered. This project will model the change in environmental and consumptive water use during exten ....Vulnerabilities for environmental water outcomes in a changing climate. This project aims to assess the vulnerability of freshwater ecosystems to extended droughts in a variable and changing climate. Governments around the world are investing in the restoration of regulated river systems with environmental water. However, the risks of climate change for environmental water management are seldom considered. This project will model the change in environmental and consumptive water use during extended dry periods, and couple this to models of ecological dynamics and failure thresholds. This will improve the success of Australia’s major environmental water programs in sustaining benefits through future multi-year droughts.Read moreRead less

Long-term planning is vital to secure Australia’s water resources in the face of environmental disruption. This project aims to contribute to sustainable and equitable water management by examining the efficacy of anticipatory decision-making approaches. Qualitative research will be used to examine how scientific knowledge is used or contested in water reform within the Murray-Darling Basin. Intended outcomes include improved capacities to plan for future change and establishing anticipatory decision-making within Australian natural resource management. This should provide significant benefits based on an integrated approach to science and decision-making that addresses trade-offs between stakeholders to identify shared action pathways.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
Long-term acid rock and tailings drainage mitigation through source control. Effective long-term management of acid rock drainage (ARD) from sulfidic mine wastes in current, exhausted and legacy mine sites is of critical importance to communities and for sustainable mining. An optimised geochemical and microbial multi-barrier approach to long-term reduction of ARD to environmentally acceptable rates will be developed by this project.
Working with recovery: Future proofing our rivers against floods & droughts. It's happening! Rivers in coastal NSW are showing signs of recovery. 25 years of improved management has increased the structural and vegetative roughness of river channels. Getting the ‘fibre’ back into rivers has impacted most positively on flood hydrology, but less so on riparian vegetation quality. This project aims to understand how river recovery occurs, its impact on flood flows and test new techniques to improve ....Working with recovery: Future proofing our rivers against floods & droughts. It's happening! Rivers in coastal NSW are showing signs of recovery. 25 years of improved management has increased the structural and vegetative roughness of river channels. Getting the ‘fibre’ back into rivers has impacted most positively on flood hydrology, but less so on riparian vegetation quality. This project aims to understand how river recovery occurs, its impact on flood flows and test new techniques to improve vegetation quality. It will investigate where corridors of recovery are, where to prioritise rehabilitation and the cost:benefit of working with recovery. This will benefit public policy, improve flood and drought risk analysis, and change decision-making and rehabilitation practice - essentially future proofing our rivers.Read moreRead less
The ecological impact of large carnivore restoration. This project aims to assess the ecological changes that have arisen due to the repatriation of estuarine crocodiles to Australian ecosystems. It is significant because the restoration provides a rare opportunity to empirically test changes in ecosystem processes under varying degrees of large carnivore predation pressure. Expected outcomes include improved understanding of the processes that govern the strength of predator-ecosystem interacti ....The ecological impact of large carnivore restoration. This project aims to assess the ecological changes that have arisen due to the repatriation of estuarine crocodiles to Australian ecosystems. It is significant because the restoration provides a rare opportunity to empirically test changes in ecosystem processes under varying degrees of large carnivore predation pressure. Expected outcomes include improved understanding of the processes that govern the strength of predator-ecosystem interactions and an ability to quantify the biomass, social structure, and behaviours of predators required to influence these processes. Benefits should include improvements in how the ecological role of large carnivores is measured, and when and where carnivore populations should be culled or conserved.Read moreRead less
A new end use of recycled water for sustainable Australian water. The economic, environmental and social impacts of this project would have benefits across Australia, and the rest of the world. Recycled water has never been used in clothes washing machines anywhere in the world, by introducing it here in Australia we would save approximately 20% of domestic water used for laundry purposes. This also has significant policy implications as this would be a huge step towards the implementation of a ....A new end use of recycled water for sustainable Australian water.
