AI in agriculture: hybrid machine learning models for nitrogen simulation. Agricultural simulation models are used to guide nitrogen management to reduce nitrogen loss and its environmental impact, but they were developed using constrained datasets, which restricts them to site- or regional-specific simulations. This project adopts a novel approach to addressing these problems by applying machine learning-based data analytics.

Agricultural simulation models are used to guide nitrogen management to reduce nitrogen loss and its environmental impact, but they were developed using constrained datasets, which restricts them to site- or regional-specific simulations. This project adopts a novel approach to addressing these problems by applying machine learning-based data analytics. The project will refine the linkages between nitrogen losses and their key drivers, and improve the existing agroecosystem models through data imputation, parameter optimisation and module enhancement. The outcomes of this project will lead to an accurate prediction of nitrogen losses from agriculture, advancement in agroecosystem models and their adaptability to a global context.Read moreRead less

Summary
Barking up the right trees – A microbial solution for our methane problem. This project aims to unveil the microbial diversity and metabolic capabilities of bark-dwelling microbial communities in Australian forests. Trees perform an important climatic function in sequestering atmospheric carbon, however the role of tree bark-associated microbiome in regulating other climate-active trace gasses such as methane, hydrogen and carbon monoxide is unknown. Combining cutting-edge molecular and biogeoch ....Barking up the right trees – A microbial solution for our methane problem. This project aims to unveil the microbial diversity and metabolic capabilities of bark-dwelling microbial communities in Australian forests. Trees perform an important climatic function in sequestering atmospheric carbon, however the role of tree bark-associated microbiome in regulating other climate-active trace gasses such as methane, hydrogen and carbon monoxide is unknown. Combining cutting-edge molecular and biogeochemical approaches, this project aims to characterise and quantify trace gas oxidation rates of forest bark microbiome. The anticipated outcomes include fundamental knowledge surrounding bark-associated microbial trace gas oxidation within global biogeochemical cycles, and insights into their response to climatic variables.Read moreRead less

Summary
Cave microbial metabolism as a missing biogeochemical sink. The aim of this project is to unveil the microbial biodiversity, novel metabolic capabilities and chemosynthetic primary production of subsurface ecosystems, such as those found in caves. Leveraging a powerful blend of geospatial, molecular and biogeochemical approaches this project expects to identify the microbial basis of subsurface biogeochemical processes driving the earth’s major elementary cycles. Expected outcomes include a pred ....Cave microbial metabolism as a missing biogeochemical sink. The aim of this project is to unveil the microbial biodiversity, novel metabolic capabilities and chemosynthetic primary production of subsurface ecosystems, such as those found in caves. Leveraging a powerful blend of geospatial, molecular and biogeochemical approaches this project expects to identify the microbial basis of subsurface biogeochemical processes driving the earth’s major elementary cycles. Expected outcomes include a predictive framework to assess and upscale the impact of these microbial communities on the environment. Benefits include predicting and responding to climate risks, such as the desertification of agricultural soils, by uncovering how microorganisms respond to nutrient and carbon depletion.Read moreRead less

Microplastics accumulation in Australian coastal wetlands. This project aims to quantify the intensity, rate and impact of the accumulation of microplastic particles in Australia’s coastal wetlands for the first time. This multidisciplinary project will examine interactions between microplastics, wetland ecology and carbon dynamics using advanced analytical chemistry, biogeochemistry and environmental microbiology. Expected outcomes of this project include the world’s first nationwide analysis o ....Microplastics accumulation in Australian coastal wetlands. This project aims to quantify the intensity, rate and impact of the accumulation of microplastic particles in Australia’s coastal wetlands for the first time. This multidisciplinary project will examine interactions between microplastics, wetland ecology and carbon dynamics using advanced analytical chemistry, biogeochemistry and environmental microbiology. Expected outcomes of this project include the world’s first nationwide analysis of the sequestration of microplastics and their influence on the carbon cycle in coastal ecosystems. This work will provide significant benefits, such as facilitating decision-making about microplastics emissions reduction and coastal wetlands conservation.Read moreRead less
Chemicals in compostable food contact paper packaging materials. The aim of this project is to understand the presence of persistent chemicals in recyclable and compostable food contact materials (FCMs). These types of products are destined for recycling or biowaste streams that bridge the gap from take-make-dispose and into a circular economy. Currently, the knowledge of the chemicals in these products is limited but we need to ensure that they are safe and do not unnecessarily contaminate reso ....Chemicals in compostable food contact paper packaging materials. The aim of this project is to understand the presence of persistent chemicals in recyclable and compostable food contact materials (FCMs). These types of products are destined for recycling or biowaste streams that bridge the gap from take-make-dispose and into a circular economy. Currently, the knowledge of the chemicals in these products is limited but we need to ensure that they are safe and do not unnecessarily contaminate resource recovery streams. It is expected that this project will develop a framework that could be used by industry and government to prevent chemicals of concern persisting in a circular economy, providing environmental and economic benefits through reduced risk of chemical exposure and unnecessary remediation costs.Read moreRead less
