The aim of this project is to assess the impacts of future disruptive climate events and disasters on Australia's food system. This will be achieved by developing a world-first Integrated Assessment Modelling Lab, a collaborative research platform for comprehensive assessment of the effects of extreme climate events (bushfires/drought/floods/cyclones) on Australia's food supply. The project will use this capability to assess impacts on Australia's national and international supply chains, industry sectors and on socio-economic groups. The outcomes will offer opportunities to improve national responses to the changing climate and build resilience by designing adaptation plans to safeguard national and international food supply chains.Read moreRead less
Shaping a sunburnt country: fire, climate and the Australian landscape. Fire shapes Australia’s landscape, biodiversity and resources. This project aims to quantify the recent history of fire intensity and severity using several novel proxies in the fire-prone landscapes of south-eastern Australia. Calibration of these new proxies to recent wildfires will be used for a better characterisation of fire regimes. This research will be applied to sedimentary archives to investigate how fire regimes h ....Shaping a sunburnt country: fire, climate and the Australian landscape. Fire shapes Australia’s landscape, biodiversity and resources. This project aims to quantify the recent history of fire intensity and severity using several novel proxies in the fire-prone landscapes of south-eastern Australia. Calibration of these new proxies to recent wildfires will be used for a better characterisation of fire regimes. This research will be applied to sedimentary archives to investigate how fire regimes have evolved over the past 100 years. The outcomes will inform debates about the relationship between climatic variability and fire severity, and this will contribute to increase the preparedness of natural resource management to potential future climate and land-use scenarios.Read moreRead less
Past trends and future risk of climate extremes in southern Australia. Prolonged droughts and periods of heightened flood and fire risk present a major challenge for Australia’s society and economy. This proposal aims to better resolve the causes and risks of decadal climate extremes through a suite of high quality records of temperature, rainfall/evaporation and humidity in southern Australia over 2000 years. Novel geochemical analyses will be developed and applied to lake sediments – method de ....Past trends and future risk of climate extremes in southern Australia. Prolonged droughts and periods of heightened flood and fire risk present a major challenge for Australia’s society and economy. This proposal aims to better resolve the causes and risks of decadal climate extremes through a suite of high quality records of temperature, rainfall/evaporation and humidity in southern Australia over 2000 years. Novel geochemical analyses will be developed and applied to lake sediments – method development which is likely to benefit climate, minerals and biosecurity research. New knowledge of mechanisms underlying climate variability is expected to benefit fundamental research, while future-facing models will allow land managers and policy makers to better anticipate extraordinary climate events.Read moreRead less
Back to the Future: Interglacial Warming and the West Antarctic Ice Sheet . The Antarctic is highly-sensitive to abrupt changes caused by the passing of tipping points within the climate system. Crucially, the instrumental record is too short to resolve major uncertainties surrounding future warming. The Last Interglacial (125,000 yrs ago) was 2°C warmer than today and experienced 6-11 m higher global sea levels. The role of Antarctica is vital for constraining sea-level projections. This Austra ....Back to the Future: Interglacial Warming and the West Antarctic Ice Sheet . The Antarctic is highly-sensitive to abrupt changes caused by the passing of tipping points within the climate system. Crucially, the instrumental record is too short to resolve major uncertainties surrounding future warming. The Last Interglacial (125,000 yrs ago) was 2°C warmer than today and experienced 6-11 m higher global sea levels. The role of Antarctica is vital for constraining sea-level projections. This Australian-led international project aims to determine the mechanisms and impacts of past interglacial Antarctic warming up to 2°C (relative to pre-industrial). Innovative techniques integrating horizontal ice cores and high resolution marine records will help identify polar tipping points and better plan for impacts in Australia.Read moreRead less

This project aims to establish the first Australian indoor air monitoring program that identifies hazardous chemicals and their sources and trends under a changing climate. The project expects to provide key evidence to policy-making decisions including prioritising indoor chemical threats for regulation. The expected outcomes include the establishment of criteria for home recruitment for indoor pollution research, identification of new chemical pollutants and their sources, and assessment of their trends. The benefit is to advance the knowledge on indoor exposure research, raise the awareness of the climate change conditions, addressing the government priority research area of Environmental Change.Read moreRead less
Working with recovery: Future proofing our rivers against floods & droughts. It's happening! Rivers in coastal NSW are showing signs of recovery. 25 years of improved management has increased the structural and vegetative roughness of river channels. Getting the ‘fibre’ back into rivers has impacted most positively on flood hydrology, but less so on riparian vegetation quality. This project aims to understand how river recovery occurs, its impact on flood flows and test new techniques to improve ....Working with recovery: Future proofing our rivers against floods & droughts. It's happening! Rivers in coastal NSW are showing signs of recovery. 25 years of improved management has increased the structural and vegetative roughness of river channels. Getting the ‘fibre’ back into rivers has impacted most positively on flood hydrology, but less so on riparian vegetation quality. This project aims to understand how river recovery occurs, its impact on flood flows and test new techniques to improve vegetation quality. It will investigate where corridors of recovery are, where to prioritise rehabilitation and the cost:benefit of working with recovery. This will benefit public policy, improve flood and drought risk analysis, and change decision-making and rehabilitation practice - essentially future proofing our rivers.Read moreRead less
Unravelling how aquatic coastal networks regulate nitrogen removal . The aim of this project is to determine the nitrogen removal pathways of the coastal zone using a number of innovative field and modelling approaches. Little is known about how the complex coastal landscape controls trade-offs that maximise nitrogen removal but minimise nitrous oxide (a potent greenhouse gas) emissions. The outcomes of this study will significantly advance our understanding of the coastal zone in regional and g ....Unravelling how aquatic coastal networks regulate nitrogen removal . The aim of this project is to determine the nitrogen removal pathways of the coastal zone using a number of innovative field and modelling approaches. Little is known about how the complex coastal landscape controls trade-offs that maximise nitrogen removal but minimise nitrous oxide (a potent greenhouse gas) emissions. The outcomes of this study will significantly advance our understanding of the coastal zone in regional and global nitrogen budgets. This will provide significant benefits such as a new science-based quantitative framework to facilitate best practice management to reduce terrestrial nitrogen loads and associated downstream impacts such as eutrophication, and reduce nitrous oxide emissions and associated global warming.

Global climate change and coastal landscape evolution in southern Australia. This project aims to reconstruct environmental changes that occurred in southern Australia during a geologically recent time interval termed the Early-Middle Pleistocene Transition (1.2 million to 700 thousand years ago) and an interglacial period some 400,000 years ago. Using innovative geochronological, geochemical and modelling techniques, the environmental changes that shaped modern Australian coastal landscapes, in ....Global climate change and coastal landscape evolution in southern Australia. This project aims to reconstruct environmental changes that occurred in southern Australia during a geologically recent time interval termed the Early-Middle Pleistocene Transition (1.2 million to 700 thousand years ago) and an interglacial period some 400,000 years ago. Using innovative geochronological, geochemical and modelling techniques, the environmental changes that shaped modern Australian coastal landscapes, including the intensification of aridity and their timing will be examined. The project will yield new knowledge about the sensitivity of landscapes to current and ongoing environmental changes and derive explanatory models of the rates and characteristics of landscape response to assist future coastal environmental management.Read moreRead less

This project aims to give a systematic account of how states facing different dynamics of threats associated with climate change have gone about developing distinct institutional responses, policy settings and practices. Climate change is increasingly recognised as a national security threat. A range of states have developed climate security strategies to address climate change that threaten defence infrastructure and contribute to population movements, regional instability and even conflict. The findings from this project will inform recommendations for Australian policy-makers in addressing the climate change-security relationship that can be communicated to practitioners, and tailored to the needs of Australia’s security and defence establishment. This project will help Australia respond effectively to pressing impacts of environmental change.Read moreRead less
