People and Parks: The Real Value of Open Space in Western Sydney. The Western Sydney Parklands (WSP), a corridor of 5500 contiguous hectares, will be the largest urban park in the southern hemisphere - an extraordinary open space resource. This study uses quantitative and qualitative research techniques to gauge 'imageability' and feelings of 'attachment' and 'connectedness' to the Parklands experienced by residents of Western Sydney. We will construct new thematic layers for an existing Geograp ....People and Parks: The Real Value of Open Space in Western Sydney. The Western Sydney Parklands (WSP), a corridor of 5500 contiguous hectares, will be the largest urban park in the southern hemisphere - an extraordinary open space resource. This study uses quantitative and qualitative research techniques to gauge 'imageability' and feelings of 'attachment' and 'connectedness' to the Parklands experienced by residents of Western Sydney. We will construct new thematic layers for an existing Geographic Information Systems database that incorporate subjective values about open space. This expanded understanding of feelings of connectedness will reveal shared community values and enhance future planning and design of urban parklands.Read moreRead less
The impacts of land ownership change on rural social and economic change. This project aims to develop a comprehensive framework for explaining how and why rural land is changing hands, what this means for the ways we understand socio-economic change in rural Australia, and how it can inform best-practice rural and regional decision making by public, private and community sector interests. The project will generate a unique, research-ready database that will detail every land transaction in rura ....The impacts of land ownership change on rural social and economic change. This project aims to develop a comprehensive framework for explaining how and why rural land is changing hands, what this means for the ways we understand socio-economic change in rural Australia, and how it can inform best-practice rural and regional decision making by public, private and community sector interests. The project will generate a unique, research-ready database that will detail every land transaction in rural NSW over a period of ten years, and analyse these data in light of complementary datasets and a series of in-depth interviews with land-owners and key stakeholders. The project expects to transform national understanding of rural land-ownership change, and promote best practice decision making.Read moreRead less
Reducing export of acid sulfate soil products (particularly iron, aluminium, phosphorus, and organic carbon) as contaminants to coastal waters. Current Australian management of acid sulfate soils (ASS) emphasises the reduction of acidity in floodplain drainage. However this acidity is mainly from the dissolved metals, which can be increased by some management techniques. Dissolved metals can be biotoxic or encourage harmful coastal phytoplankton. Organic metal complexes can increase metal tran ....Reducing export of acid sulfate soil products (particularly iron, aluminium, phosphorus, and organic carbon) as contaminants to coastal waters. Current Australian management of acid sulfate soils (ASS) emphasises the reduction of acidity in floodplain drainage. However this acidity is mainly from the dissolved metals, which can be increased by some management techniques. Dissolved metals can be biotoxic or encourage harmful coastal phytoplankton. Organic metal complexes can increase metal transport but shading of soil and drain surfaces, and constructed wetlands offers a new management tool. Our research aims to reduce transport to coastal waters of these ASS products. A sustainable Australian coast requires that improvement of ASS floodplains must not be at the environmental expense of coastal waters. Read moreRead less
Measuring the impact of urban regulation on housing affordability in Australian cities and regions. Urban planning must ensure that development meets new environmental goals, but stringent regulation may reduce housing supply and affordability. This project uses new local planning data and econometric studies to quantify and monitor planning regulation impacts on housing supply and affordability in Australian cities and regions.
Transforming invasive plant management in northern Australia. This project aims to investigate how rapid socio-ecological transformation in northern Australia is reconfiguring invasive plant management, and evaluate the social and cultural factors and development context that contributes to its effectiveness. Through innovative qualitative research, the project will generate new knowledge of plant introductions, the emerging assemblages of people and practices that are facilitating or disrupting ....Transforming invasive plant management in northern Australia. This project aims to investigate how rapid socio-ecological transformation in northern Australia is reconfiguring invasive plant management, and evaluate the social and cultural factors and development context that contributes to its effectiveness. Through innovative qualitative research, the project will generate new knowledge of plant introductions, the emerging assemblages of people and practices that are facilitating or disrupting change, and the consequences for Indigenous people dealing with land-use change. Expected outcomes include enhancing Australia's environmental management capacity by identifying opportunities for more effective invasive plant management, and more equitable and sustainable sharing of the benefits it brings.Read moreRead less
Avoiding Environmental Bankruptcy: the grazing impacts of red kangaroos and sheep. Overgrazing is one of the most serious environmental and economic problems in Australia. By mitigating overgrazing, our project has three major benefits. Firstly, quantification of the foraging requirements for free-ranging sheep and kangaroos will, for the first time, allow us to identify sustainable practices that prevent overgrazing and contribute to significant land recovery. Secondly, a new mechanistic model ....Avoiding Environmental Bankruptcy: the grazing impacts of red kangaroos and sheep. Overgrazing is one of the most serious environmental and economic problems in Australia. By mitigating overgrazing, our project has three major benefits. Firstly, quantification of the foraging requirements for free-ranging sheep and kangaroos will, for the first time, allow us to identify sustainable practices that prevent overgrazing and contribute to significant land recovery. Secondly, a new mechanistic model for predicting herbivore dynamics will allow us to evaluate potential impacts of climate change on future grazing pressures. Thirdly, our results will inform management plans to sustain Australia's arid rangelands as productive, bio-diverse environments, which currently provide economic returns in excess of $20 billion p.a.Read moreRead less

This project aims to develop a policy appraisal tool that shows the consequences of land use decisions. The proposed integrated multi-level modelling framework—linked to models that monitor demographics evolution, travel demand, energy, labour, economy, housing and household dynamics—can assess sustainability, equity and economy. This framework is expected to help people make better decisions about housing, maintain system level properties such as price equilibrium, show the impact of land use in the transport system, and improve policy appraisal for city planning.Read moreRead less
Synthesis of Activated Carbon Supported Zero Valent Iron Nanoparticles and Application to Contaminant Degradation in Benthic Sediments. Sediment contamination is a major problem in harbours and estuaries around Australia. For example, in Sydney Harbour, a total fishing ban has been implemented as a result of excessive levels of dioxins and benzofurans in fish tissues. There is also concern at the possibility of large scale contamination of Botany Bay as a result of historic industrial activity a ....Synthesis of Activated Carbon Supported Zero Valent Iron Nanoparticles and Application to Contaminant Degradation in Benthic Sediments. Sediment contamination is a major problem in harbours and estuaries around Australia. For example, in Sydney Harbour, a total fishing ban has been implemented as a result of excessive levels of dioxins and benzofurans in fish tissues. There is also concern at the possibility of large scale contamination of Botany Bay as a result of historic industrial activity around the Bay. While dredging and on-land treatment of sediments is being adopted at the most severely contaminated sites, the cost of this approach is exorbitant. For sites where removal of contaminated sediments cannot be justified, the approach proposed in this study of a technology that entraps contaminants and enhances their in situ biodegradation is potentially a way forward.Read moreRead less
