Motor vehicles constitute one of the most significant sources of air pollutants but the state of knowledge on the quantity of some of these does not permit for projection of the risk they create. This project aims at quantification of emissions of pollutants contributing to deterioration of health, ozone formation, global warming and acid rain as a function of fuel type, using a novel on-road sampling method. Resultantly, a holistic picture of integrated health and environmental risk will be developed that will build a scientific foundation for future fuel,transport and land use to protect the community and the environment.Read moreRead less
Multi-Country Study on Health Effects of Bushfire Air Pollution. Catastrophic bushfires are a major natural disaster, causing serious air pollution. However, aligning bushfire air pollution and public health policies becomes a significant challenge, because limited studies are available on relationships between bushfire air pollution and human health, particularly for the prolonged exposure. We will characterize the nature of the relationships between bushfire air pollution and mortality/morbidi ....Multi-Country Study on Health Effects of Bushfire Air Pollution. Catastrophic bushfires are a major natural disaster, causing serious air pollution. However, aligning bushfire air pollution and public health policies becomes a significant challenge, because limited studies are available on relationships between bushfire air pollution and human health, particularly for the prolonged exposure. We will characterize the nature of the relationships between bushfire air pollution and mortality/morbidity by developing a multi-country study; and estimate the burden of diseases attributed to bushfire air pollution. This project will provide essential scientific evidence to policy-makers and stakeholders in the development, prioritization and implementation of health protection strategies and policies.

This project will extend the theory and practice of decision science to explore the question of how the apparently divergent objectives of biodiversity conservation and economic development can be balanced. The human modification of natural landscapes is causing species loss to accelerate. Yet land use and infrastructure developments are often necessary to support economic growth. The project plans to develop new methods to map past and project future development scenarios for the lower Mekong region in south-east Asia, a globally significant region undergoing rapid economic development. Novel problem formulations would be used to balance biodiversity conservation with development objectives.Read moreRead less
Impact of increased sediment and nutrient discharges on the long-term sustainability of the Great Barrier Reef. The Great Barrier Reef, one of Australia's greatest natural assets, is under increasing threat from extreme climatic events caused by global warming and from land-based pollution. This research will identify the main sources of sediment and nutrient pollution caused by river runoff and by how much this has increased above 'natural levels'. We will discover how the very sensitive offsho ....Impact of increased sediment and nutrient discharges on the long-term sustainability of the Great Barrier Reef. The Great Barrier Reef, one of Australia's greatest natural assets, is under increasing threat from extreme climatic events caused by global warming and from land-based pollution. This research will identify the main sources of sediment and nutrient pollution caused by river runoff and by how much this has increased above 'natural levels'. We will discover how the very sensitive offshore coral reefs have responded to increased pollution and whether this is the cause of the very devastating crown-of-thorn-starfish infestations. Understanding the long-term effects of land-based pollution on the ecology of coral reefs in the GBR will thus provide a scientific basis to help ensure that it has a sustainable future.Read moreRead less
Environmental fingerprints of biogeochemical cycles embedded in tree rings: Linking global climate change to local long-term forest productivity. Forests cover one-third of the Earth's land surface and account for 80-90% of plant carbon and 30-40% of soil carbon. Forest carbon stocks and dynamics respond to and interact with global climate change (GCC). Recent tree ring research highlights the worsening impact of GCC and acid deposition on long-term forest productivity in central Europe.
