The role of epigenetic modifications in bovid adaptation to environmental change. This project will explore the role of epigenetic change, where gene expression is regulated without changing the deoxyribonucleic acid (DNA) sequence, in how animals adapt to rapid climate change. This project will trace epigenetic markers in ancient bison and cows through 30,000 years of climate change, and identify key adaptive genes for the cattle industry.
Fires, black carbon, greenhouse gas emissions and the carbon balance of southern sclerophyll forests. Ecologically sustainable forest management requires an understanding of the role of fire in the carbon balance of native forests, and in Australia's overall carbon balance. Fires are crucial to both this carbon balance and to the ecology of the forests. This project will help forest managers make decisions about using prescribed fire to manage fuels while at the same time managing carbon. An ....Fires, black carbon, greenhouse gas emissions and the carbon balance of southern sclerophyll forests. Ecologically sustainable forest management requires an understanding of the role of fire in the carbon balance of native forests, and in Australia's overall carbon balance. Fires are crucial to both this carbon balance and to the ecology of the forests. This project will help forest managers make decisions about using prescribed fire to manage fuels while at the same time managing carbon. An aim of management is to identify fire regimes that will optimise the carbon outcome as well as provide protection to life and property. This project will help managers meet that aim by developing a quantitative understanding of how much stable, black carbon (charcoal) is produced and how it affects other soil processes.Read moreRead less
Improving long term forecasts of tree growth in carbon farming projects. Australia is taking action to limit global warming, including use of "carbon farming" to capture CO2 using trees as natural carbon sinks. Limited knowledge on the growth rate of Mulga trees, a primary carbon sink, hampers our partner organisation’s ability to maximise carbon stores. The aim of this proposal is to use dendrochronology to inform novel predictive models for growth of mulga trees that will reduce uncertainty in ....Improving long term forecasts of tree growth in carbon farming projects. Australia is taking action to limit global warming, including use of "carbon farming" to capture CO2 using trees as natural carbon sinks. Limited knowledge on the growth rate of Mulga trees, a primary carbon sink, hampers our partner organisation’s ability to maximise carbon stores. The aim of this proposal is to use dendrochronology to inform novel predictive models for growth of mulga trees that will reduce uncertainty in carbon removal forecasts. The expected outcome will be significant and benefit our partner organisation and other agencies by providing improved forecasting of tree growth that will inform their decisions for investment in carbon farming and nature repair markets.Read moreRead less
Optimising community-based climate change adaptation in the Pacific Islands. Optimising community-based climate change adaptation in the Pacific Islands. This project aims to evaluate community level climate change interventions in the Pacific to provide guidelines for better practice. The effects of climate change—rising sea levels, more droughts, and more frequent and intense storm activity—have been particularly concentrated in tropical areas such as the Pacific Islands. In response, interven ....Optimising community-based climate change adaptation in the Pacific Islands. Optimising community-based climate change adaptation in the Pacific Islands. This project aims to evaluate community level climate change interventions in the Pacific to provide guidelines for better practice. The effects of climate change—rising sea levels, more droughts, and more frequent and intense storm activity—have been particularly concentrated in tropical areas such as the Pacific Islands. In response, interventions to adapt to a diversity of impacts have accelerated at the community level across the region, but there has been no analysis of their long-term effectiveness in reducing livelihood and resource vulnerability to climate change.Read moreRead less
Reengineering a dynamic vegetation model to explore the stability of Australian terrestrial carbon. Overseas models do not represent Australian biophysical processes well: our flora and fauna are unique and our soils are old and nutrient poor. In contrast, the National Carbon Accounting System (NCAS) is a world-class framework for estimating current carbon processes. By building NCAS expertise into an overseas model of soil and vegetation processes we can develop the capacity to increase our con ....Reengineering a dynamic vegetation model to explore the stability of Australian terrestrial carbon. Overseas models do not represent Australian biophysical processes well: our flora and fauna are unique and our soils are old and nutrient poor. In contrast, the National Carbon Accounting System (NCAS) is a world-class framework for estimating current carbon processes. By building NCAS expertise into an overseas model of soil and vegetation processes we can develop the capacity to increase our confidence in future projections of carbon and vegetation change. Our proposal, linking Universities, CSIRO and the Australian Greenhouse Office establishes a team that is internationally competitive. It will enhance local expertise and local model development to ensure national policy development is underpinned by world-class science.Read moreRead less
Silicon: a novel solution to reduce water use and pest damage in wheat. The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si a ....Silicon: a novel solution to reduce water use and pest damage in wheat. The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si alleviates stress in wheat, from gene to farm scale, providing cost-benefit analysis and a best–practice toolbox for implementation by farmers. Outcomes are anticipated to provide a cheaper and more environmentally sustainable solution to issues of water scarcity and yield losses to pests in Australia’s leading crop.Read moreRead less

Assessing the adaptive capacity of hospital facilities to cope with climate-related extreme weather events: A risk management approach. Given Australia's and New Zealand's relatively high exposure to climate extremes, the social, economic and health benefits of better managed hospital facilities are significant. Floods, bushfires, heatwaves and cyclones cost Australia over $1.4bn/year and New Zealand over NZ$43m/yr in disruption to communities, business productivity and damage to infrastructure. ....Assessing the adaptive capacity of hospital facilities to cope with climate-related extreme weather events: A risk management approach. Given Australia's and New Zealand's relatively high exposure to climate extremes, the social, economic and health benefits of better managed hospital facilities are significant. Floods, bushfires, heatwaves and cyclones cost Australia over $1.4bn/year and New Zealand over NZ$43m/yr in disruption to communities, business productivity and damage to infrastructure. This research will help to mitigate these costs by protecting populations from the health risks associated with such events. The potential benefits will be most significant for those vulnerable communities at high risk such as the aged, the obese, the ill and those geographically exposed to more extreme weather events.Read moreRead less

This project aims to improve our understanding of the capacity of trees to respond to climate change. This is essential for the maintenance of biodiversity, forest health and productivity. In south-west Australia, climate variation has increased the frequency and intensity of droughts, which has resulted in tree death and negatively affected essential ecosystem services. Adaptive land management is urgently needed to mitigate the risk of large-scale drought mortality in a rapidly changing climate. This project seeks to deliver a scientific basis for the adoption of assisted gene migration in south-west forests, through a detailed understanding of genetic adaptation and physiological tolerance, to improve drought-resilience under future hotter and drier climates.Read moreRead less
