Resolving the problem of environmental degradation on agricultural land, which is 60% of Australia’s land surface, is a major challenge. By engaging with farmers whose innovative practices have generated environmental and productivity benefits, this project aims to investigate the co-constructive relationship between land ownership, land use decision making and geography. The project tackles conventional accounts treating private property rights in agricultural land as unavoidably opposed to environmental goals. A key projected outcome is a set of rich case studies showing how geography shapes land use decision-making. This new approach provides much-needed evidence to inform law reform that transcends the public law/private rights impasse.Read moreRead less

Seeing the good from the trees: remotely sensing the urban forest. Urban forests provide a range of ecosystem services including temperature regulation and rainfall capture, but measuring these benefits is currently prohibitively costly and inaccurate. This project aims to develop a new model of urban forest ecosystem services that uses remotely sensed three dimensional data to map canopy cover. A model using this data, which is being collected by an increasing number of governments, represents ....Seeing the good from the trees: remotely sensing the urban forest. Urban forests provide a range of ecosystem services including temperature regulation and rainfall capture, but measuring these benefits is currently prohibitively costly and inaccurate. This project aims to develop a new model of urban forest ecosystem services that uses remotely sensed three dimensional data to map canopy cover. A model using this data, which is being collected by an increasing number of governments, represents a novel advance on the established methodology that requires expensive and time-consuming fieldwork. The advancements expected to be made in this project will mean that environmental planners will be able to better plan the urban forest so that cities are more liveable and resilient in the face of climate change.Read moreRead less
DESIGNING LAND ADMINISTRATION SYSTEMS TO SUPPORT MODERN LAND MARKETS. Economies require successful land markets to generate wealth. Our land administration systems are expensive but essential infrastructure for land markets. However, since they were designed 150 years ago, the market has invented complex commodities: time shares, unit and property trusts, financial instruments, mortgage backed certificates, insurance products, options, corporate development instruments, vertical villages, and ....DESIGNING LAND ADMINISTRATION SYSTEMS TO SUPPORT MODERN LAND MARKETS. Economies require successful land markets to generate wealth. Our land administration systems are expensive but essential infrastructure for land markets. However, since they were designed 150 years ago, the market has invented complex commodities: time shares, unit and property trusts, financial instruments, mortgage backed certificates, insurance products, options, corporate development instruments, vertical villages, and more. The project will explain how modern land markets evolved and how land administration systems can be adapted to provide more efficient land trading and better support for trading in new complex commodities.

Toxic cyanobacterial blooms in a carbon dioxide (CO2)-rich world: assessing the impacts of global climate change. Cyanobacterial blooms in Australia cost the country over $150 million every year because of their impacts on water quality and animal and human health. The frequency, distribution and intensity of these blooms are all expected to increase worldwide as global climate change impacts increase over the next century. This project will provide much needed information of the severity of imp ....Toxic cyanobacterial blooms in a carbon dioxide (CO2)-rich world: assessing the impacts of global climate change. Cyanobacterial blooms in Australia cost the country over $150 million every year because of their impacts on water quality and animal and human health. The frequency, distribution and intensity of these blooms are all expected to increase worldwide as global climate change impacts increase over the next century. This project will provide much needed information of the severity of impacts on cyanobacteria commonly causing blooms in Australian aquatic ecosystems. This information will be important to authorities responsible for managing our precious water resources.Read moreRead less
Experimental and theoretical analysis of gas leakage rate through composite landfill covers due to geomembrane defects. The Australian Greenhouse Office indicated that waste emissions contributed 3.1% of net national emissions in 2001 with methane emissions from landfills accounting for 92% of total methane emissions from the waste sector, despite an increase in methane recovered from solid waste. It pointed out that the recent changes in waste management practices did not have an impact on repo ....Experimental and theoretical analysis of gas leakage rate through composite landfill covers due to geomembrane defects. The Australian Greenhouse Office indicated that waste emissions contributed 3.1% of net national emissions in 2001 with methane emissions from landfills accounting for 92% of total methane emissions from the waste sector, despite an increase in methane recovered from solid waste. It pointed out that the recent changes in waste management practices did not have an impact on reported methane emission levels and there is need to undertake a range of activities to reduce emissions from waste management activities. This project will address specifically the above issue by providing a new method of analysis to predict gas leakage rate and allow engineers to propose solutions to mitigate gas escapes.

Millions of dollars are being spent on rehabilitating river ecosystems that have often been highly simplified by human activities. It is important that such rehabilitation be well-grounded in sound ecological knowledge. We will test how the availability of essential resources of food and living space affect the identity and density of species present. We expect to provide practical advice allowing managers to enhance biodiversity in streams surrounded by, and serving, agricultural areas. Likewise, we will be able to advise on the consequences of excessive water extraction on the likely success of such rehabilitation in rivers with highly variable flows.Read moreRead less
