The way we manage catchments under climate change is one of Australia’s major public policy challenges. This project will give new direction to catchment management by developing a science-policy linked, systemic and adaptive water governance mechanism. By recommending policy options for more sustainable water use and creating favourable social-institutional factors for the implementation of these policy options in two Australian catchment authorities through comparative and parallel research in China and South Africa. This project directly addresses the national priority goals of “Water - a critical resource” and “Responding to climate change”. This project will also stress Australia's important role in this globally significant issue. Read moreRead less

This project aims to understand the co-evolution of science, culture and management policy in water catchment for improving the predictability and preciseness of the water management policy.
Active-passive microwave soil moisture remote sensing: Towards sustainable land and water management from space. Soil moisture is a highly critical resource for the Australian agricultural economy which is stressed by climate change. Daily monitoring of paddock scale soil moisture from space represents a powerful tool to inform land management, allowing accurate crop yield and pasture growth predictions. At the continental scale, soil moisture information will result in better weather, climate a ....Active-passive microwave soil moisture remote sensing: Towards sustainable land and water management from space. Soil moisture is a highly critical resource for the Australian agricultural economy which is stressed by climate change. Daily monitoring of paddock scale soil moisture from space represents a powerful tool to inform land management, allowing accurate crop yield and pasture growth predictions. At the continental scale, soil moisture information will result in better weather, climate and extreme flood prediction skill and the ability to assess the effects of future climate change on Australia. It is therefore imperative that active-passive soil moisture retrieval algorithms be developed specifically for the Australian environment in order to take full advantage of the SMAP remote sensing mission when it is launched in 2012.Read moreRead less
High resolution mapping of surface and root zone soil moisture. Knowledge of the spatial and temporal variation of surface and root zone soil moisture content at high spatial resolution is critical to achieving more efficient water utilisation practices in agriculture. Australia's main river basins are under mounting pressure to satisfy a wide range of competing economic, social and environmental needs for water, particularly in terms of environmental flows and efficient irrigation. A better u ....High resolution mapping of surface and root zone soil moisture. Knowledge of the spatial and temporal variation of surface and root zone soil moisture content at high spatial resolution is critical to achieving more efficient water utilisation practices in agriculture. Australia's main river basins are under mounting pressure to satisfy a wide range of competing economic, social and environmental needs for water, particularly in terms of environmental flows and efficient irrigation. A better understanding of the soil moisture distribution at sub-farm scales will allow farmers to better utilise both the moisture in their soil and their limited allocation for irrigation. This will help alleviate soil moisture related problems in some of the nation's key catchments, such as the Murray Darling Basin.Read moreRead less

Remotely sensed forest water use in space and time. This project aims to develop and apply new methods to scale forest water use from plot to catchment-level, using relationships between plot-level annual evapotranspiration and biophysical and biochemical properties of stands detectable by unmanned aircraft systems and other remote sensing platforms. Australia's water security depends on understanding how changes in forests from disturbance and climate change influence catchment water yields. This project will estimate water yields over time and space in ungauged catchments with disturbed eucalypt forests. This research is expected to enable more effective risk mitigation and planning for augmentations; improved fire management strategies; and better water management of the Murray Darling Basin.Read moreRead less
New methods for mapping variation in forest water use in time and space. Disturbance of eucalypt forests can have dramatic impacts on catchment water yields.

Mitigating extreme water supply contamination in bushfire burned catchments. This project involves Melbourne Water, the Department of Environment and Primary Industries, and East Gippsland Water in developing tools to evaluate mitigation options that will protect our water supplies and increase the resilience of Australian communities to bushfire. Major bushfires in south-east Australia in 2003, 2007, 2009 and 2013 were followed by storms that triggered extreme soil erosion events in catchments, ....Mitigating extreme water supply contamination in bushfire burned catchments. This project involves Melbourne Water, the Department of Environment and Primary Industries, and East Gippsland Water in developing tools to evaluate mitigation options that will protect our water supplies and increase the resilience of Australian communities to bushfire. Major bushfires in south-east Australia in 2003, 2007, 2009 and 2013 were followed by storms that triggered extreme soil erosion events in catchments, contaminating water supplies and damaging critical infrastructure. The capacity to mitigate the risk of interruption to the water supplies of our cities and towns in a more fire-prone future is currently limited by our knowledge of where, why, and how often these post-fire contamination events will occur. This project aims to address these knowledge gaps.Read moreRead less
