The melioidosis agent Burkholderia pseudomallei in the anthropogenic environment of northern Australia. This project will analyse environmental factors contributing to the persistence of the soil bacterium and melioidosis agent, Burkholderia pseudomallei in the anthropogenic environment. This will increase understanding of the consequences of land use manipulations upon these bacteria and will suggest remediation measures to reduce the risk of exposure.
Understanding cultural and ecological triggers for policies against water catchment degradation. You cannot step into the same river twice. This project aims to understand the co-evolution of science, culture and management policy in water catchment for improving the predictability and preciseness of the water management policy.
Better water management through more focus on ecological and social sciences. Current water resources management, focusing on gains of economic efficiency in the short term under the assumption of steady-state conditions, has generally failed to respond to both catchment environmental degradation and to the increasing complexity of human–environment interactions. This project will develop a new approach to water resources management by relating management practices based on ecological understand ....Better water management through more focus on ecological and social sciences. Current water resources management, focusing on gains of economic efficiency in the short term under the assumption of steady-state conditions, has generally failed to respond to both catchment environmental degradation and to the increasing complexity of human–environment interactions. This project will develop a new approach to water resources management by relating management practices based on ecological understanding to the social mechanisms behind these practices at water catchments. It will improve the predictability and precision of water resources management and increase our ability to maintain our options for a sustainable future. This will have a profound effect on catchment sustainability, a globally significant problem.Read moreRead less
Tracing Past and Present Pollution Sources in the River Torrens, South Australia. The Torrens River is the principal water supply to 500,000 South Australians. Since early in European settlement it has suffered the impacts of eutrophication and high rates of sedimentation. The Catchment Management Board is seeking to prioritise rehabilitation resources to maximise water quality improvements. This will be informed by the revelation of the principal sources of sediment and nutrients over time.
Indicators of ecosystem health in Western Australian recovery catchments. Dryland salinity and rural community decline in Australia are important and inter-related issues. Any ecosystem recovery actions proposed to address salinity should be examined for their potential to assist rural communities, rather than exacerbate their problems. The framework theories of ecosystem health and participatory research embrace these issues. A PhD student placed in each of two recovery catchments will use meth ....Indicators of ecosystem health in Western Australian recovery catchments. Dryland salinity and rural community decline in Australia are important and inter-related issues. Any ecosystem recovery actions proposed to address salinity should be examined for their potential to assist rural communities, rather than exacerbate their problems. The framework theories of ecosystem health and participatory research embrace these issues. A PhD student placed in each of two recovery catchments will use methodologies adapted for these approaches to develop indicators for the detection of trends in recovery or deterioration of ecosystem and community well-being. This will allow for adaptive changes to recovery actions, and for an analysis of causal relationships.Read moreRead less
Bushfires, smoke, and people: assessing the risks and benefits from planned burning on the urban-rural interface. A key strategy to protect people from wildfire is the use of planned burns to reduce fire hazards. The exposure of communities to smoke pollution is a serious side-effect of this intervention. This project will be critical in enabling authorities to protect public health by determining acceptable levels of smoke originating from planned burns.
Bad tastes, odours and toxins in our drinking water reservoirs: are benthic cyanobacteria the culprits? Cyanobacteria (blue-green algae) produce toxins and bad tastes that contaminate drinking water sources, cause public concern about water quality. This project will address a critical knowledge gap by investigating species that grow on the sediments of reservoirs, thus providing more comprehensive management solutions to the water industry.
Predicting water quality at the catchment scale: learning from two decades of monitoring. Poor water quality affects many rivers and receiving waters such as the Great Barrier Reef and Gippsland Lakes. This project aims to use Bayesian hierarchical models of statewide water quality data to quantify the effects of a range of factors on stream water quality including climate, land use, river flow, vegetation cover, etcetera. The analysis intends to extract information from the entire data set rath ....Predicting water quality at the catchment scale: learning from two decades of monitoring. Poor water quality affects many rivers and receiving waters such as the Great Barrier Reef and Gippsland Lakes. This project aims to use Bayesian hierarchical models of statewide water quality data to quantify the effects of a range of factors on stream water quality including climate, land use, river flow, vegetation cover, etcetera. The analysis intends to extract information from the entire data set rather than concentrating on individual sites. It intends to underpin a new predictive capacity including response to land use and management changes and climatic variations based on long-term data sets, as well as a water quality prediction capability. It is intended that the models developed will jointly model a range of inter-related water quality parameters.Read moreRead less
