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.
Innovative approaches to managing and understanding taste and odour in drinking water systems. Taste and odour (T/O) problems resulting from Cyanobacteria can change consumers' perception of product safety, resulting in many complaints, soaring management and treatment costs, and large financial losses, yet little is known about how they arise.
This project will provide the Australian Water Industry with cost-effective, sensitive, specific, rapid and practical tools for managing and understandi ....Innovative approaches to managing and understanding taste and odour in drinking water systems. Taste and odour (T/O) problems resulting from Cyanobacteria can change consumers' perception of product safety, resulting in many complaints, soaring management and treatment costs, and large financial losses, yet little is known about how they arise.
This project will provide the Australian Water Industry with cost-effective, sensitive, specific, rapid and practical tools for managing and understanding T/O episodes, and will also benefit the aquaculture and food sectors, and the research community. An improved ability to manage geosmin in drinking water, will also have positive repercussions on the Australian environment, by eliminating the need to use environmentally controversial control methods such as copper sulphate dosing.

Nitrous oxide and methane emissions from South East Queensland waterways and influence of wastewater discharges. Climate change caused by greenhouse gas emissions is one of the most serious challenges facing mankind. Substantial emission reduction must be achieved, with responsibilities to be shared by all sectors. Rivers, estuaries and water storages contribute considerably to global nitrous oxide and methane emissions, much of which is anthropogenic contributed by urban and agricultural run-of ....Nitrous oxide and methane emissions from South East Queensland waterways and influence of wastewater discharges. Climate change caused by greenhouse gas emissions is one of the most serious challenges facing mankind. Substantial emission reduction must be achieved, with responsibilities to be shared by all sectors. Rivers, estuaries and water storages contribute considerably to global nitrous oxide and methane emissions, much of which is anthropogenic contributed by urban and agricultural run-off and wastewater discharges. Through an in-depth study on several rivers, estuaries and reservoirs in South East Queensland, this project will provide data to enable reliable estimation of such emissions in Australia, and deliver knowledge and tool support for the development of strategic catchment management strategies.Read moreRead less
Diffusion of manufactured high performance green houses: a mixed-methods management study of innovation obstacles. This project will improve the affordability and environmental impact of Australian housing, by increasing the rate of innovation activity within the industry. The project addresses this challenge by investigating the beliefs of builders that underpin their reticence to change. The findings are used to design educational responses to improve innovation rates.
Conservation of tropical forests for their carbon and biodiversity values. International efforts to save tropical forests for the carbon they store could help mitigate climate change and biodiversity loss. This project will aid these efforts by developing methods to model future deforestation and extending decision theory for the new challenges presented by international carbon-payment schemes.

Predicting fisheries change from cumulative impacts to aquatic habitats. This project intends to quantify the role that aquatic habitats play in fisheries, and to help identify where to restore degraded aquatic habitats. Fisheries are a globally important resource but their status is declining in many regions, often because of the loss of aquatic habitats. However, the role of habitat in fishery declines is poorly quantified, and new models are needed that integrate existing datasets to attribut ....Predicting fisheries change from cumulative impacts to aquatic habitats. This project intends to quantify the role that aquatic habitats play in fisheries, and to help identify where to restore degraded aquatic habitats. Fisheries are a globally important resource but their status is declining in many regions, often because of the loss of aquatic habitats. However, the role of habitat in fishery declines is poorly quantified, and new models are needed that integrate existing datasets to attribute change in a fishery to change in its habitats. The project aims to develop a new statistical analysis to examine the role of habitat loss in the global status of fisheries and how multiple human impacts to habitats affect fisheries, to decide how we can best protect aquatic habitats.Read moreRead less

Summary
Purification of contaminated wastewaters by modified Bayer layered double hydroxides. This project intends to develop enhanced adsorbent materials, prepared from industrial wastewater and seawater, for the decontamination of environments affected by Australian industries. This inexpensive novel material will be applicable to a wide range of purification applications and will reduce the environmental impact of Australian industries.
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.
Mapping Australia to identify local, regional, and national values. This project aims to map landscape values and preferences to describe Australia’s human landscape. Landscape values measure place importance; preferences measure social acceptability of development options. When both are mapped for representative populations, they identify potential land conflict, assess the compatibility of zoning and development plans, and prioritise areas for future conservation and development. This project ....Mapping Australia to identify local, regional, and national values. This project aims to map landscape values and preferences to describe Australia’s human landscape. Landscape values measure place importance; preferences measure social acceptability of development options. When both are mapped for representative populations, they identify potential land conflict, assess the compatibility of zoning and development plans, and prioritise areas for future conservation and development. This project will develop a national geospatial database of landscape values using internet-based public participation geographic information systems (PPGIS) and volunteered geographic information (VGI) systems. This can inform future land use planning and development at local, regional, and national levels.Read moreRead less
