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
Enhancing nutrient retention in soils through management of microbial biomass. Soil microbial-processes are generally studied in relation to mineralisation of nutrients but rarely for their potential to retain nutrients and reduce nutrient leaching. We hypothesise that management of microbial immobilisation will enhance nutrient retention in nutrient enriched soils during seasonal rains. This hypothesis will be tested under strongly seasonal environments of southwest Australia where nutrient lea ....Enhancing nutrient retention in soils through management of microbial biomass. Soil microbial-processes are generally studied in relation to mineralisation of nutrients but rarely for their potential to retain nutrients and reduce nutrient leaching. We hypothesise that management of microbial immobilisation will enhance nutrient retention in nutrient enriched soils during seasonal rains. This hypothesis will be tested under strongly seasonal environments of southwest Australia where nutrient leaching from soils degrades quality of surface and groundwater. We will first investigate pathways and conditions leading to microbial immobilisation. We will then explore the regulation of substrate and nutrient conditions to promote such retention, and subsequently develop management interventions based on microbially-mediated nutrient retention.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

The project will demonstrate the integration of water quality and economic modelling and how it can influence policy and investment in conservation and remediation.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
Institutional transitions to sustainable agriculture: An inter-disciplinary analysis of a novel common-property resource governance system. Efforts to overcome the severe degradation of land resources supporting agriculture and human communities continue to be constrained by institutions and social norms. The knowledge needed for a transition to sustainable agricultural landscapes through institutional change is inadequate.

Efforts to overcome the severe degradation of land resources supporting agriculture and human communities continue to be constrained by institutions and social norms. The knowledge needed for a transition to sustainable agricultural landscapes through institutional change is inadequate. A collaboration between specialists in economics, politics, sociology, ecology and soil science at the University of New England and graziers in an upper Murray-Darling subcatchment will analyse the transition to a common-property institution on this subcatchment. It will make a distinctively Australian contribution to international efforts to understand such transitions, and serve as a model for progress towards sustainability elsewhere in Australia.

The economic wealth of Australia is underpinned by its remarkable biological diversity. However, land and water degradation are eroding Australia's natural asset base damaging industries such as tourism, fisheries, and forestry. Given limited funds for biodiversity conservation, we need to minimise the misallocation of resources by making wise investments. This research will result in frameworks and tools to ensure that we maximise the protection of biological diversity and the delivery of ecosystem services (such as clean water) that are important for human well-being. We will share the results of our research with decision makers, scientists, and the general public.Read moreRead less
