This project will develop a quality scientific and technological program in national priority areas, leading to a strong basic research, new concepts and the enhanced international collaborative links; strengthen links between basic and applied research, and academia and industry; develop excellence via pan-Australian collaborations, resulting in a more efficient use of resources in a national and international context; enhance the skills-base in biology, biotechnology and chemistry; increase global visibility with increased investment in Australian science; improve animal welfare and production via improved control of infectious diseases; producing commercial products with benefits to agricultural producers in regional & rural communities.Read moreRead less
Novel, Cost-Effective Methods for Measuring Methane Emissions from Grazing Livestock. Agriculture is second only to energy generation as a source of greenhouse gas emissions in Australia. Methane from cattle and sheep constitute 60% of these agricultural emissions. Their abatement is a win-win goal for the agricultural industry, reducing greenhouse emissions while increasing food efficiency. This project will develop a novel, cost- and-labour efficient method for on-farm measurements of the emis ....Novel, Cost-Effective Methods for Measuring Methane Emissions from Grazing Livestock. Agriculture is second only to energy generation as a source of greenhouse gas emissions in Australia. Methane from cattle and sheep constitute 60% of these agricultural emissions. Their abatement is a win-win goal for the agricultural industry, reducing greenhouse emissions while increasing food efficiency. This project will develop a novel, cost- and-labour efficient method for on-farm measurements of the emissions of methane from free-grazing cattle and sheep in their undisturbed environment. The method will be used to assess the dependence of methane emissions on factors such as diet and the efficacy of proposed methods for abatement of methane emissions, as well as providing improved data to the National Greenhouse Gas Inventory.Read moreRead less
Molecular approaches to solving current and emerging problems in the epidemiology and diagnosis of Marek's disease in Australia. Marek's disease (MD) is a ubiquitous viral disease of chickens that is currently controlled in meat chickens by blanket vaccination of all chickens. However, as has happened overseas, the efficacy of the HVT vaccine being used in Australia is breaking down resulting in subclinical and clinical losses due to MD. To assist industry deal with this situation we propose to ....Molecular approaches to solving current and emerging problems in the epidemiology and diagnosis of Marek's disease in Australia. Marek's disease (MD) is a ubiquitous viral disease of chickens that is currently controlled in meat chickens by blanket vaccination of all chickens. However, as has happened overseas, the efficacy of the HVT vaccine being used in Australia is breaking down resulting in subclinical and clinical losses due to MD. To assist industry deal with this situation we propose to develop novel molecular methods for the quantification of Marek's disease viruses (MDV) in the host and the environment, to use these methods to design effective early monitoring systems for MD in broilers that predict disease and performance outcomes, and to develop an epidemiological model that will predict the spread and severity of MD as failure of vaccinal protection progresses.Read moreRead less
Nutrient generation from rural land and delivery to streams in the Sydney Drinking Water Catchments. The Sydney Catchment Authority must manage pollution arising from land within its catchments. There have been few local studies of nutrient losses from rural land, the major land use, and the understanding of some important processes involved in nutrient generation and delivery is weak. Therefore model predictions are uncertain. This project will quantify nutrient losses from key land uses, ev ....Nutrient generation from rural land and delivery to streams in the Sydney Drinking Water Catchments. The Sydney Catchment Authority must manage pollution arising from land within its catchments. There have been few local studies of nutrient losses from rural land, the major land use, and the understanding of some important processes involved in nutrient generation and delivery is weak. Therefore model predictions are uncertain. This project will quantify nutrient losses from key land uses, evaluate alternative loss pathways, and provide insight into the effects of scale, providing a foundation for improved modelling of nutrient sources and transport. The outcome will be the capacity to prioritise land uses and parts catchments for remedial action, whilst providing a modelling approach relevant to the SCA and other catchment managers.Read moreRead less
Measurement of paddock scale pasture biomass using synthetic aperture radar remote sensing. To maintain the long-term viability of livestock production, producers and land managers need access to regular, timely and accurate estimates of pasture biomass. Radar remote sensing has the capacity to consistently provide this information at the paddock, farm and catchment scale in a timely manner to assist in tactical and strategic decision making for sustainable pasture and livestock management. Econ ....Measurement of paddock scale pasture biomass using synthetic aperture radar remote sensing. To maintain the long-term viability of livestock production, producers and land managers need access to regular, timely and accurate estimates of pasture biomass. Radar remote sensing has the capacity to consistently provide this information at the paddock, farm and catchment scale in a timely manner to assist in tactical and strategic decision making for sustainable pasture and livestock management. Economic analyses undertaken at the farm level have revealed the potential to double farm profit by increasing the utilization of pasture grown. In addition to the socio-economic benefits, the environmental benefits of sustainable land management are paramount in light of the current drought in Australia and the global climate change.Read moreRead less
Avoiding Environmental Bankruptcy: the grazing impacts of red kangaroos and sheep. Overgrazing is one of the most serious environmental and economic problems in Australia. By mitigating overgrazing, our project has three major benefits. Firstly, quantification of the foraging requirements for free-ranging sheep and kangaroos will, for the first time, allow us to identify sustainable practices that prevent overgrazing and contribute to significant land recovery. Secondly, a new mechanistic model ....Avoiding Environmental Bankruptcy: the grazing impacts of red kangaroos and sheep. Overgrazing is one of the most serious environmental and economic problems in Australia. By mitigating overgrazing, our project has three major benefits. Firstly, quantification of the foraging requirements for free-ranging sheep and kangaroos will, for the first time, allow us to identify sustainable practices that prevent overgrazing and contribute to significant land recovery. Secondly, a new mechanistic model for predicting herbivore dynamics will allow us to evaluate potential impacts of climate change on future grazing pressures. Thirdly, our results will inform management plans to sustain Australia's arid rangelands as productive, bio-diverse environments, which currently provide economic returns in excess of $20 billion p.a.Read moreRead less
