This project aims to address the escalating threats to coastal freshwater fish from drought, fire, and other disturbances. The project expects to generate new knowledge on contemporary distributions of NSW coastal freshwater fishes, and will develop models of population dynamics to explore the consequences of alternative water management and disturbance scenarios. The expected outcome of the project is to revolutionise management by replacing the current practice of managing river basins separately, with a framework that accounts for among-basin linkages that are essential for the long-term persistence of fish populations. Significant benefits include more efficient use of water resources and improved conservation outcomes for native fish.Read moreRead less
Multi-Objective Optimal Operation of Urban Water Supply Systems. In recent past, there has been a significant shift away from development of new water resources to optimal operation of existing reservoir systems. This project aims to develop a decision support framework to determine optimum operating rules of existing reservoir systems that consider a range of economic, environmental and social criteria, with a strong focus on decision analysis of alternative operating rules. The results of the ....Multi-Objective Optimal Operation of Urban Water Supply Systems. In recent past, there has been a significant shift away from development of new water resources to optimal operation of existing reservoir systems. This project aims to develop a decision support framework to determine optimum operating rules of existing reservoir systems that consider a range of economic, environmental and social criteria, with a strong focus on decision analysis of alternative operating rules. The results of the project will enable water planners to manage their urban water systems efficiently and effectively under a range of long term and short term planning conditions including droughts, while reducing associated environmental impacts.Read moreRead less
Natural resource management and enterprise development: can they improve Indigenous livelihoods? High on the Australian agenda is the removal of disadvantage faced by Indigenous groups and the sustainable use of biodiversity on Indigenous land. In terms of Eastern Indonesia, the Australian agenda relates to poverty eradication, with fewer threats to Australian borders in terms of illegal fishing and migration. This project provides fundamental knowledge on household resource use patterns, and th ....Natural resource management and enterprise development: can they improve Indigenous livelihoods? High on the Australian agenda is the removal of disadvantage faced by Indigenous groups and the sustainable use of biodiversity on Indigenous land. In terms of Eastern Indonesia, the Australian agenda relates to poverty eradication, with fewer threats to Australian borders in terms of illegal fishing and migration. This project provides fundamental knowledge on household resource use patterns, and the constraints and opportunities for natural resource activities, as a step towards identifying ways in which natural resources can be mobilised to improve livelihoods.

Analysis of Possible Rules for Interstate Water Trading by the Australian Capital Territory. Rules will be studied and modelled for allowing ACT water trading with other states, within an agreed abstraction cap. The aim is to find administrative, constraining and price-setting rules that maximise the economic gain of trading to Australia, bearing in mind environmental constraints, infrastructure costs, transaction costs, and equity. Innovative challenges for the rules will be allowing ACT to se ....Analysis of Possible Rules for Interstate Water Trading by the Australian Capital Territory. Rules will be studied and modelled for allowing ACT water trading with other states, within an agreed abstraction cap. The aim is to find administrative, constraining and price-setting rules that maximise the economic gain of trading to Australia, bearing in mind environmental constraints, infrastructure costs, transaction costs, and equity. Innovative challenges for the rules will be allowing ACT to sell water now but buy it back later, thus providing for long term population growth; and handling the differences between ACT's spare storage capacity and urban uses, and the downstream irrigation uses with which trade is most likely.Read moreRead less

Detecting ecological impacts of water extraction on river ecosystem structure and function: Validating a novel decision-making protocol. Reliable assessment of ecological responses to flow alteration coupled with management triggers to prevent unacceptable impact is essential in rivers where water extraction occurs. Most regulated rivers lack optimal monitoring programs to provide early indications of over-extraction. We aim to apply a novel framework (Downes et al. 2002) to optimize sampling ....Detecting ecological impacts of water extraction on river ecosystem structure and function: Validating a novel decision-making protocol. Reliable assessment of ecological responses to flow alteration coupled with management triggers to prevent unacceptable impact is essential in rivers where water extraction occurs. Most regulated rivers lack optimal monitoring programs to provide early indications of over-extraction. We aim to apply a novel framework (Downes et al. 2002) to optimize sampling efficiency of structural and functional variables to determine whether extractions from the Nymboida River, NSW, are preventing the system from achieving its desired ?target?. If validated, this innovative framework that specifies effect size, statistical power, and management triggers will be invaluable for common situations where pre-impact data are lacking.Read moreRead less
Marine conservation planning for persistent coral reef communities: Incorporating connectivity and resilience. Australia's biological diversity underpins much of our economic wealth - for example the remarkable diversity of coral reefs fuels a multibillion dollar tourism industry. However, despite substantial efforts to conserve marine ecosystems, Australian coral reefs are at increasing risk from climate change related catastrophes. To counteract this trend, we must choose marine reserve networ ....Marine conservation planning for persistent coral reef communities: Incorporating connectivity and resilience. Australia's biological diversity underpins much of our economic wealth - for example the remarkable diversity of coral reefs fuels a multibillion dollar tourism industry. However, despite substantial efforts to conserve marine ecosystems, Australian coral reefs are at increasing risk from climate change related catastrophes. To counteract this trend, we must choose marine reserve networks using methods that account for the dynamic nature of climate change and reef community responses to maximise the persistence of reef biodiversity. The new theory and methods will enable us to create more effective and economically efficient marine reserve systems.Read moreRead less
Improving water market outcomes through a better understanding of market behaviour. The issue of water resources and their sustainable use is probably the most important issue facing the rural sector.

The issue of water resources and their sustainable use is probably the most important issue facing the rural sector. The water reform process and its aim to secure water for the environment will cause economic and social pain and result in structural change within the irrigation sector. Properly functioning water markets will play an instrumental role in facilitating this process by providing water for the environment and allowing water to move between competing resources. This study will enable policy makers and water managers to optimise the positive outcome of water markets and increase the likely success of programs to purchase environmental water.Read moreRead less
