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
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.
Water, carbon, and economics: resolving complex linkages for river health. By linking landscapes into our emerging low-carbon economy, this project will investigate how land management practices can be improved through payments for ecosystem services. With a focus on water and carbon, the main goal is to develop mechanisms to support integrated land and water management at the catchment scale.
