Resources, industry and rural communities, the backbone of Australian economy, are confronted by unprecedented challenges of carbon pollution reduction, land conservation and eco-sustainability to combat global climate change. This exciting, highly integrated and multidisciplinary project will develop a scientific basis and technological options for the resources industry and remote communities to respond to these challenges. The outcomes of this research will enable the deployment of renewable biomass energy technology, bio-char for carbon storage, and affect the restoration of marginal lands and salinity levels in an environmentally and economically sustainable way, thus contributing to the development of an environmentally sustainable Australia.Read moreRead less
Anticipating closure of bauxite refineries in Western Australia: the water quality implications of a proposed new design in residue storage areas. Refining bauxite is a major industrial activity in Australia, with economic benefits and a high potential for environmental impact. Many bauxite refineries are sited in rural areas. Community interests are given high priority in developing strategies for long-term storage of residue. These community interests include minimal impact on farmland, water, ....Anticipating closure of bauxite refineries in Western Australia: the water quality implications of a proposed new design in residue storage areas. Refining bauxite is a major industrial activity in Australia, with economic benefits and a high potential for environmental impact. Many bauxite refineries are sited in rural areas. Community interests are given high priority in developing strategies for long-term storage of residue. These community interests include minimal impact on farmland, water, health and natural ecosystems. Some of the refinery residue can be re-used in applications such as road construction, thus reducing the need to find other materials for this purpose. This project will investigate new residue management practices which could lead to better ways of establishing a sustainable vegetation cover and avoiding the impact of drainage water on the environment.Read moreRead less
Utilising novel Pongamia trees to decarbonise Australia’s beef value-chain. Progress towards a carbon neutral beef industry typically focusses on nutritional strategies, overlooking potential innovations in farming system configuration. This project aims to develop a framework for the integration of Pongamia into beef production systems, so that not only emissions reductions are maximised, but also to support carbon capture and farm system resilience. This project seeks to determine the impact o ....Utilising novel Pongamia trees to decarbonise Australia’s beef value-chain. Progress towards a carbon neutral beef industry typically focusses on nutritional strategies, overlooking potential innovations in farming system configuration. This project aims to develop a framework for the integration of Pongamia into beef production systems, so that not only emissions reductions are maximised, but also to support carbon capture and farm system resilience. This project seeks to determine the impact of Pongamia meal on cattle production efficiency, meat quality and methane emissions. Through quantification of carbon sequestration potential in tree plantations, whole-farm modelling will elucidate production scenarios capable of achieving the reductions needed for a carbon neutral Australian beef industry.Read moreRead less
Deciphering interactions of conducting polymers in agricultural soils. The project aims to improve agricultural efficiency, productivity and yield by advancing the understanding of polymer materials interacting with fertiliser. This project will test the key assumptions behind a new sensor for real-time in-ground monitoring of fertiliser. The expected outcome from this is the rapid synthesis of conducting polymers for stable sensing of fertiliser in a range of soil types and conditions. This sho ....Deciphering interactions of conducting polymers in agricultural soils. The project aims to improve agricultural efficiency, productivity and yield by advancing the understanding of polymer materials interacting with fertiliser. This project will test the key assumptions behind a new sensor for real-time in-ground monitoring of fertiliser. The expected outcome from this is the rapid synthesis of conducting polymers for stable sensing of fertiliser in a range of soil types and conditions. This should provide the pathway to a world first real-time in-ground fertiliser sensor, providing benefit for the sensor manufacturers, farmers, consumers and the environment.Read moreRead less
Resolving the role of kelp in blue carbon cycles to enable management. We aim to uncover how kelp forests contribute to carbon storage, biodiversity enhancement and nutrient mitigation in Australia. We will combine mapping and modelling to identify local variation in kelp carbon stocks and sequestration potential and verify kelp carbon export to deep ocean sinks through genetic tracing in seawater and sediments. Co-benefits will be identified through nutrient experiments and reef surveys. We wil ....Resolving the role of kelp in blue carbon cycles to enable management. We aim to uncover how kelp forests contribute to carbon storage, biodiversity enhancement and nutrient mitigation in Australia. We will combine mapping and modelling to identify local variation in kelp carbon stocks and sequestration potential and verify kelp carbon export to deep ocean sinks through genetic tracing in seawater and sediments. Co-benefits will be identified through nutrient experiments and reef surveys. We will also assess the risk that calcification and production of halogenic gas within the kelp forest could offset its climate mitigation potential. Project outcomes will enable management to consider kelp ecosystem services broadly and optimize our capacity to meet current emission reduction and biodiversity commitments.Read moreRead less
Farming in a biodiversity hotspot - harnessing native plants to reduce deleterious off-site phosphorus flows. Biodiversity hotspots that coexist with farmland are often threatened by movement of phosphorus off farmland into waterways and into vegetation adapted to low phosphorus soils. Strategic use of phosphorus-resistant native perennial plants may aid biodiversity preservation by retaining phosphorus in farmland soils.
Unlocking mine waste potential: carbon sequestration and metals extraction. This project aims to systematically investigate a proof-of-concept engineering process for transforming mine waste into value. The research will develop and employ state-of-the-art tools to advance our knowledge of efficiently sequestering carbon dioxide using ultramafic nickel mine tailings, while also enabling the extraction of critical metals—particularly nickel—and the production of value-added products, such as high ....Unlocking mine waste potential: carbon sequestration and metals extraction. This project aims to systematically investigate a proof-of-concept engineering process for transforming mine waste into value. The research will develop and employ state-of-the-art tools to advance our knowledge of efficiently sequestering carbon dioxide using ultramafic nickel mine tailings, while also enabling the extraction of critical metals—particularly nickel—and the production of value-added products, such as high-purity magnesium carbonate hydrate and silica. Successful outcomes from this research will provide benefits for mitigating global warming, supplying critical metals for renewable energy technologies, and facilitating the transition of Australia's mining industry towards sustainability.Read moreRead less
Assessing and addressing tax system complexity in Australia. Tax reform and simplification are highly topical in government, business and the wider community, with many initiatives proposed or under way. This project will identify the key factors in tax system complexity, measure the costs it imposes upon taxpayers and develop complexity indices that can test new policy measures and monitor improvements.
Cooperation, competition or control? Public policy and the use of tied grants in Australian federalism. Tied grants account for $26 billion worth of Commonwealth expenditure and cover everything from child care to aged care, environmental programs to road building. They crucially affect the capacity of Australian governments to make policy and deliver services. A better understanding of how they work in practice will be a great benefit in improving our capability to meet pressing social, econo ....Cooperation, competition or control?
