The project aims to create a quantitative modelling framework for assessing the absolute sustainability of cities by combining global multi-region input-output analysis with the 'safe and just space' concept for human development. The model will allow assessment of the full supply chain environmental and social impacts of urban economic activities against biophysical planetary limits as well as social foundation thresholds defined in the literature. The project will advance sustainability science methodology and will greatly benefit worldwide initiatives for urban sustainability. Case studies on Australian cities will assess where interventions can be most practically, realistically and effectively implemented.Read moreRead less

This project aims to develop consumer-centred approaches to reducing the harmful effects of confusion in financial decisions by studying superannuation investment and home loan decisions where confused choices are individually and collectively costly. The project intends to develop comprehensive models to capture the full complexity of financial products and the diverse preferences and capability of consumers, then to use advanced statistical methods to estimate the benefits of clearer decision-making. The outcomes of this project includes new models of complex financial decisions, and a better understanding of where confusion arises and the effects it may have. Decreased confusion will raise financial well-being and help communities become more resilient to financial shocks.Read moreRead less
Modern statistical methods for clustering community ecology data. This project will develop statistical methods and software for clustering community ecology data, and use them to analyse systematic survey and citizen science program data collected along the Great Barrier Reef. By doing so, the project will address the dearth of statistical classification techniques for high-dimensional, multi-response data with complex relationships. When the resultant clustering methods are used to construct b ....Modern statistical methods for clustering community ecology data. This project will develop statistical methods and software for clustering community ecology data, and use them to analyse systematic survey and citizen science program data collected along the Great Barrier Reef. By doing so, the project will address the dearth of statistical classification techniques for high-dimensional, multi-response data with complex relationships. When the resultant clustering methods are used to construct bioregions and characterise species’ environmental responses, they should significantly enhance evaluations of the impact of human activity and environmental change on coral diversity. Ultimately, these evaluations can underpin future decisions in the conservation and management of the Great Barrier Reef.Read moreRead less
Microplastic infiltration of food webs: cells to ecosystem consequences. Using trophic ecological theory as a framework, this project aims to provide the first comprehensive assessment of the fate and effects of microplastics. Plastic pollution is a persistent and increasing problem. Plastics are degraded into small particles, called microplastics, which are ingested by animals. The project aims to develop much-needed techniques to measure microplastics in biological tissue and apply these techn ....Microplastic infiltration of food webs: cells to ecosystem consequences. Using trophic ecological theory as a framework, this project aims to provide the first comprehensive assessment of the fate and effects of microplastics. Plastic pollution is a persistent and increasing problem. Plastics are degraded into small particles, called microplastics, which are ingested by animals. The project aims to develop much-needed techniques to measure microplastics in biological tissue and apply these techniques in food web studies to determine the capacity of microplastics to transfer from the environment into animals, and how microplastics move through a food web to affect biological diversity and animal health. This information will be used to complete the first risk assessment for microplastics in a major coastal habitat.Read moreRead less

Assessment of plant health and productivity is vital to ensure future food security of the global population under a changing climate. Chlorophyll fluorescence (CF), a signal emitted by green plants, can reveal this information. Although CF has revolutionised photosynthetic research, current measurements are limited to individual plants. Remote sensing of canopy CF is required for efficient management of agricultural crops, forests, and natural ecosystems and is crucial for accurate estimation of plant carbon assimilation and production. This project will deliver remote sensing technology to bridge the gap between leaf and canopy productivity and pave the way for understanding both artificial and solar induced canopy CF measured from space.Read moreRead less
Improving water quality modelling by better understanding solute transport. Poor stream water quality is a critical problem in Australia and globally. Stream water quality depends directly on pathways and time taken for water to transport pollutants through catchments. Predicting these pathways is highly challenging and currently requires specialised data.

Poor stream water quality is a critical problem in Australia and globally. Stream water quality depends directly on pathways and time taken for water to transport pollutants through catchments. Predicting these pathways is highly challenging and currently requires specialised data. This project aims to better model the movement of water from rainfall to streams, enable greatly improved use of water quality data routinely collected in Australia's catchments and thereby better predict water quality behaviour. Proposed field studies aim to support this development. The outcomes sought are improved planning and management of water quality in our rivers, lakes and estuaries, improved health of these water bodies and improved water supplies.Read moreRead less
Linking phytoplankton to fisheries using zooplankton size spectra. This project aims to develop innovative numerical methods to understand the dynamics, carbon export, and trophic structure of zooplankton.

This project aims to develop innovative numerical methods to understand the dynamics, carbon export, and trophic structure of zooplankton. The trophic links between phytoplankton, zooplankton and fisheries are unknown. The size- frequency distribution of zooplankton (size spectrum) is an innovative method for estimating their growth, predation and production as food for fish. Analysis of a global synthesis of zooplankton size distributions from tropical to polar environments are expected to reveal these vital rates of pelagic ecosystems. The zooplankton rates will reveal, for the first time, the link between phytoplankton and fisheries, and will significantly improve ecosystem models and global assessments of environmental change.Read moreRead less
