Halophytes for high-saline agriculture: optimising performance and understanding physiology. The recent drought has shaved off up to 1 per cent of Australia's economic growth and resulted in losses of over $6 billion in crop and livestock production. At the same time, very large volumes of water with impaired chemical quality are generated by industry and municipal water treatment processes. In most cases, these cannot be used directly for crop irrigation and have to be disposed of at extreme co ....Halophytes for high-saline agriculture: optimising performance and understanding physiology. The recent drought has shaved off up to 1 per cent of Australia's economic growth and resulted in losses of over $6 billion in crop and livestock production. At the same time, very large volumes of water with impaired chemical quality are generated by industry and municipal water treatment processes. In most cases, these cannot be used directly for crop irrigation and have to be disposed of at extreme cost and waste. This project will utilise halophytes as 'alternative cash crops' to use the saline water produced by the coal seam gas operations in the Surat Basin area in Queensland. This will result in a saving of at least $48 million over the five years of operation.Read moreRead less
Colloid interactions and extraction in sustainable, water efficient paper manufacture. This project will investigate the causes of wood extractive deposits on modern high-speed printing surfaces. The project will also develop alternatives to prevent their deposition in an environmentally sustainable manner, and to remove them from the paper making process allowing their utilisation as valuable natural products.
Finding damage thresholds in pyrethrum to optimise crop profitability. This project aims to use a new vascular approach to develop a quantitative stress tolerance framework for the crop species pyrethrum, defining the risks to plant production of water, heat and frost stress. Using novel optical and x-ray technology, this project seeks to pinpoint damaging stress thresholds and combine this knowledge with crop monitoring technology in a way that will allow crop managers to avoid damaging stress ....Finding damage thresholds in pyrethrum to optimise crop profitability. This project aims to use a new vascular approach to develop a quantitative stress tolerance framework for the crop species pyrethrum, defining the risks to plant production of water, heat and frost stress. Using novel optical and x-ray technology, this project seeks to pinpoint damaging stress thresholds and combine this knowledge with crop monitoring technology in a way that will allow crop managers to avoid damaging stress events. The intended outcome is to enable the pyrethrum industry, and ultimately a diversity of crop managers, to better utilise new advances in monitoring technology to maximise the benefits of irrigation such that yields are high relative to water use and damage by stress is avoided. Immediate beneficiaries will be the pyrethrum industry, but the research will provide a model, applicable to the multitude of irrigated crops in Australia. Read moreRead less
Are coastal wetlands vulnerable to bushfires? The ‘Black Summer’ fires burned extensive areas of coastal wetland not typically associated with fire impact. These wetlands rely upon plant growth and sediment delivery to respond to sea-level rise, processes which may be impacted by fire. This project aims to quantify the distribution and severity of fire impact, and establish post-fire vegetation and surface elevation trajectories. By integrating fire ecology and wetland science approaches, this p ....Are coastal wetlands vulnerable to bushfires? The ‘Black Summer’ fires burned extensive areas of coastal wetland not typically associated with fire impact. These wetlands rely upon plant growth and sediment delivery to respond to sea-level rise, processes which may be impacted by fire. This project aims to quantify the distribution and severity of fire impact, and establish post-fire vegetation and surface elevation trajectories. By integrating fire ecology and wetland science approaches, this project will ascertain the resilience of coastal wetlands to the cumulative impacts of fire and sea-level rise. Expected outcomes of this project include new, spatially-explicit fire management tools which will aid the sustainable, long-term management of coastal wetlands in a changing climate.Read moreRead less
AirLIFT – an airborne active chlorophyll fluorescence sensing system for assessment of photosynthetic activity in plant canopies. 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 ....AirLIFT – an airborne active chlorophyll fluorescence sensing system for assessment of photosynthetic activity in plant canopies. 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
Supporting or sabotaging sustainable development? State policy responses to environmental certification schemes. Almost everywhere, forests and fisheries are experiencing degradation and biodiversity loss. Since 1990, governments, industry and civil society organizations have expressed growing interest in market-based instruments for environmentally sustainable development. However, while states support the use of market-based instruments in general, serious problems arise with specific schemes. ....Supporting or sabotaging sustainable development? State policy responses to environmental certification schemes. Almost everywhere, forests and fisheries are experiencing degradation and biodiversity loss. Since 1990, governments, industry and civil society organizations have expressed growing interest in market-based instruments for environmentally sustainable development. However, while states support the use of market-based instruments in general, serious problems arise with specific schemes. This is particular true of environmental certification schemes, several of which have been opposed. Our study will explore the underlying factors that shape government responses to certification schemes in the forestry and fisheries sectors, thereby providing practical policy advice to ensure state institutions support rather than sabotage environmentally sustainable development.Read moreRead less
