Below-ground processes: filling the missing gap in predicting the response of grain production to elevated carbon dioxide (CO2) in southern Australia. Climate change is expected to have major impacts on the Australian grains industry, which is worth $7 billion annually. Although increases in atmospheric carbon dioxide (CO2) are expected to initially increase plant productivity, the realisation of these productivity benefits is expected to be limited by water and/or nutrient deficiencies. Given o ....Below-ground processes: filling the missing gap in predicting the response of grain production to elevated carbon dioxide (CO2) in southern Australia. Climate change is expected to have major impacts on the Australian grains industry, which is worth $7 billion annually. Although increases in atmospheric carbon dioxide (CO2) are expected to initially increase plant productivity, the realisation of these productivity benefits is expected to be limited by water and/or nutrient deficiencies. Given our low rainfall and infertile soils, there is considerable uncertainty about the applicability of overseas data used to model how Australian grain systems will respond to climate change (especially elevated CO2). This project will lead to better predictions of the impact of climate change on Australian grain systems so that appropriate adaptation responses can be developed by government and industry.Read moreRead less
Phytoextraction approaches for mitigating heavy metal release from unlined and loosely capped rural landfills. Australian rural landfills are used for storing hazardous wastes which contain toxic metals. Impermeable clay caps are often utilized to encapsulate these wastes and prevent release of pollutants into the environment. The integrity of these caps is crucial and requires constant care.

Australian rural landfills are used for storing hazardous wastes which contain toxic metals. Impermeable clay caps are often utilized to encapsulate these wastes and prevent release of pollutants into the environment. The integrity of these caps is crucial and requires constant care. The project aims to develop novel approaches which will improve substantially the long-term environmental safety of rural landfills and deliver additional economic benefits. These approaches involve the use of high-value tree crops and plants capable of extracting toxic metals. Utilization of these plants will create a valuable resource on an otherwise derelict area and this will be of considerable local/regional benefit and national significance.Read moreRead less

Refining bauxite is a major industrial activity in Australia, with economic benefits and a high potential for environmental impact. Many bauxite refineries are sited in rural areas. Community interests are given high priority in developing strategies for long-term storage of residue. These community interests include minimal impact on farmland, water, health and natural ecosystems. Some of the refinery residue can be re-used in applications such as road construction, thus reducing the need to find other materials for this purpose. This project will investigate new residue management practices which could lead to better ways of establishing a sustainable vegetation cover and avoiding the impact of drainage water on the environment.Read moreRead less

This project will examine the forms, transformations and fate of dissolved organic matter (DOM) in aquatic ecosystems and the link to human health with water treatment. Catchment revegetation is a management tool used to reduce excessive nutrient loads to waterways, which in turn causes poor water quality. However, catchment revegetation also produces DOM. DOM is typically poorly characterised and its effect on ecosystem health unclear. DOM also reacts with chlorine in water treatment plants to form disinfection by-products that affect human health. This research is expected to provide important new information to guide future catchment restoration efforts.Read moreRead less
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.

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
