Bushfire smoke and the relationship between human and landscape health. A team of landscape ecologists, environmental chemists and public health specialists will determine the ecological causes and adverse health effects of different levels of bushfire smoke in Darwin. Darwin is an ideal setting for this research because the only source of air pollution is the high incidence of controlled and uncontrolled bushfires during the dry season causing variable air quality: a preliminary study found a ....Bushfire smoke and the relationship between human and landscape health. A team of landscape ecologists, environmental chemists and public health specialists will determine the ecological causes and adverse health effects of different levels of bushfire smoke in Darwin. Darwin is an ideal setting for this research because the only source of air pollution is the high incidence of controlled and uncontrolled bushfires during the dry season causing variable air quality: a preliminary study found a link between smoke pollution levels and asthma. The findings of the proposed research will contribute to improved fire management practices to reduce injurious smoke pollution events and contribute to setting appropriate national air quality standards.Read moreRead less
Landscape-scale population dynamics of open forests in the Australian monsoon tropics. Over the last century there has been a trend of increasing tree cover in many landscapes. Yet the causes of this globally important ecological phenomenon are poorly understood, but may include the effects of climate, fire, grazing and CO2. We will determine how an area of forest has changed over 50 years in Kakadu National Park, linking forest demography with remote sensing techniques, re-measurement and analy ....Landscape-scale population dynamics of open forests in the Australian monsoon tropics. Over the last century there has been a trend of increasing tree cover in many landscapes. Yet the causes of this globally important ecological phenomenon are poorly understood, but may include the effects of climate, fire, grazing and CO2. We will determine how an area of forest has changed over 50 years in Kakadu National Park, linking forest demography with remote sensing techniques, re-measurement and analysis of long-term tree demography datasets, and simulation models of tree population dynamics on a landscape scale. This will provide a scientific framework to develop sustainable land management and the conservation of Australia's forest biodiversity.Read moreRead less
Impacts of deforestation and afforestation on greenhouse gas emissions, and carbon and water resources in the Daly River catchment, north Australia. Over the last decade, north Australia have been viewed as a potentially exploitable resource, given issues of salinisation, soil acidification, over-allocation of water resources and rainfall declines in south Australian agricultural regions. Improved pastures and plantation forestry are two land uses that may expand in the NT. Clearing of savanna v ....Impacts of deforestation and afforestation on greenhouse gas emissions, and carbon and water resources in the Daly River catchment, north Australia. Over the last decade, north Australia have been viewed as a potentially exploitable resource, given issues of salinisation, soil acidification, over-allocation of water resources and rainfall declines in south Australian agricultural regions. Improved pastures and plantation forestry are two land uses that may expand in the NT. Clearing of savanna vegetation would be required, with implications for greenhouse gas emissions, soil health, water resources and dry season environmental flows. This project will track greenhouse emissions and water use from uncleared and cleared savanna that has been converted to pasture and timber plantations, providing critical understanding of the environmental implication of such land use change in savanna.Read moreRead less
Managing acid mine drainage in northern Australia using microbial mats. One of the most difficult environmental issues for the mining industry is acid mine drainage (AMD) that can lead to significant environmental damage. This project aims to identify microbes and characterise their roles in AMD formation in north Australia. We will use our new knowledge to design and trial microbial mats for the treatment of AMD. A successful AMD microbial treatment technology will minimise the risk of acid run ....Managing acid mine drainage in northern Australia using microbial mats. One of the most difficult environmental issues for the mining industry is acid mine drainage (AMD) that can lead to significant environmental damage. This project aims to identify microbes and characterise their roles in AMD formation in north Australia. We will use our new knowledge to design and trial microbial mats for the treatment of AMD. A successful AMD microbial treatment technology will minimise the risk of acid runoff and metal seepage into rivers and through groundwater. AMD treatment technology we develop in the tropics where we experience the extremes of dry and wet seasons will require only minor modification to operate in temperate climates however the reverse is not true.

Stable lead isotopes, trace metals and radionuclides in sediments of the Alligator Rivers Region to assess impacts of uranium mining. A PhD student under the supervision of a multidisciplinary team of environmental analytical chemists, geochemists and environmental physicists will develop a new sensitive methodology to monitor impacts of past, present and future uranium mining activities in and near Kakadu National Park, although it may be applied to other mining activities as well. The method w ....Stable lead isotopes, trace metals and radionuclides in sediments of the Alligator Rivers Region to assess impacts of uranium mining. A PhD student under the supervision of a multidisciplinary team of environmental analytical chemists, geochemists and environmental physicists will develop a new sensitive methodology to monitor impacts of past, present and future uranium mining activities in and near Kakadu National Park, although it may be applied to other mining activities as well. The method will use a combination of stable lead isotopes, trace metals and radionuclide techniques. The outcomes of the research will increase the capacity of the Office of the Supervising Scientist to carry out its core function of assessing and supervising mines in the Alligator Rivers Region.Read moreRead less

Advanced Geochemical Facility for Climate and Environmental Change Research: a Western Australian/Indian Ocean focus. Research outcomes from this new facility will empower government bodies, resource industries, and indigenous stakeholders with key baseline information to ensure the sustainable and sensitive development of west Australia's unique coastal and offshore regions, across heavily populated and pristine environments. This includes projecting future impacts on local industries (eg. ener ....Advanced Geochemical Facility for Climate and Environmental Change Research: a Western Australian/Indian Ocean focus. Research outcomes from this new facility will empower government bodies, resource industries, and indigenous stakeholders with key baseline information to ensure the sustainable and sensitive development of west Australia's unique coastal and offshore regions, across heavily populated and pristine environments. This includes projecting future impacts on local industries (eg. energy, fisheries, tourism), rising shorelines with critical implications for existing and developing communities, and enhancing the resilience of habitats at risk. These are crucial to mitigate the impacts from environmental change that could severely affect our regional and national economies, as well as the style and quality of life of current and future generations.Read moreRead less
