This paper reviews water policy responses to drought in Australia, focusing on the Murray-Darling Basin (MDB) during the two decades from 1997. This period, which includes the decade long Millennium drought, brought a much sharper focus to discussions of scarcity and value of water. The drought initially focused attention on rising salinity and environmental water availability, as action on both was supported by strong science, and resonated politically. The drought became a crisis in 2006. Short-term planning focused on ensuring communities did not run out of water. For the longer term, the national government responded by announcing a major package of reform measures addressing sustainability and underlying scarcity, and recognising climate change. The package strengthened MDB water market infrastructure, upgraded water resource planning and the ability of irrigators to manage their water assets more flexibly, established new sustainable diversion limits and provided funding to ensure the environment received a larger share of basin water resources. But its completeness as a package can be attributed not only to the severity of drought, but also to political leadership, a disrupting strategy in the form of national legislation and a strong national budget that provided financial resources. The drought provided a crisis, but other ingredients were necessary to ensure effective action.

Ecological Science

The concept of environmental water requirements (EWRs) is central to Australia’s present approach to water reform. Current decision-making regarding environmental water relies strongly on the notion that EWRs necessary to meet targets associated with ecological objectives for asset sites can be scientifically defined, thus enabling the ecological outcomes of alternative water management scenarios to be evaluated in a relatively straightforward fashion in relation to these flow thresholds or targets. We argue, however, that the ecological objectives and targets currently underpinning the development of EWRs in the Murray-Darling Basin are insufficient to permit the identification of exact water requirements or flow thresholds. Because of the dynamic and heterogeneous nature of the Murray-Darling Basin and the myriad ways in which it is valued by people, we also assert that it is unlikely that adequate ecological objectives and targets from which to determine EWRs could ever be formulated. We suggest that the current emphasis on the concept of EWRs in environmental water planning conflates science and values, perpetuating a “how much is enough?” myth whereby the significance of the social, cultural and political dimension in environmental decision-making is diminished. We support an alternative paradigm in which the contribution of ecological science to water policy and management decisions focuses on understanding ecological responses of water-dependent ecosystems and their biota to alternative management scenarios and linking these responses to the ecosystem services and human values which they support.

Short Term Effects

Blackwater contains high levels of dissolved organic carbon that can be rapidly consumed by microbes, sometimes leading to extremely low levels of dissolved oxygen (hypoxia) and drastic consequences for aquatic life, including fish kills. Drought-breaking rains in late 2010 inundated large areas of the Barmah–Millewa Forest, southern Murray–Darling Basin, Australia, and resulted in a prolonged hypoxic blackwater event within the forest and the Murray River downstream. This study investigated the short-term effects of the blackwater event on fish and crayfish. Compared with non-affected sites, blackwater affected sites had: significantly higher abundances of emerged Murray crayfish (Euastacus armatus) that were vulnerable to desiccation, predation and exploitation; large numbers of dead or dying shrimp and yabbies; significantly reduced abundances of native fish; but contained similar abundances of alien fish species (particularly common carp, Cyprinus carpio). The nature of the mechanisms that caused these changes and the longer term significance of the event on the river system remains an important area for future research. We also propose a range of management considerations for reducing the blackwater impacts, such as the timing of environmental water delivery after prolonged drought and the importance of maintaining river–floodplain connectivity during flood periods.

The increasing pressure on water resources in Europe’s broader area led member states to take measures and adopt a common legislative “umbrella” of directives to protect them. The aim of this research is to investigate practicing deficiencies, information lacks and distances from optimal status as set by the Water Framework Directive and supporting water uses. This contributes to the improvement of the efficiency and harmonization of all environmental goals especially when management of Protected Areas is addressed. Gap analysis, an approach that reveals the distance between current and desired level, was carried out, targeting five Mediterranean hydro-ecosystems, covering three major water policy pillars “Monitoring Practices”, “Management Practices” and “Water Quality and Pressures”. Data for such analyses was collected by literature research supported by a query matrix. The findings revealed a lack in compliance with the Water Framework Directive regarding the “Monitoring Practices” and several deficiencies in sites burdened by eutrophication and human pressures on “Water Quality and Pressures” field. As for “Management Practices”, extra effort should be applied in all hydro-ecosystems to reach the desirable state. We suggest that gap analysis, as a harmonization tool, can unify apparently different areas under the same goals to reveal the extra necessary “investment”.

Key Dimensions

Risks and uncertainties arising from climate change are increasingly recognized as significant challenges for water governance. To support adaptive approaches, critical examinations of water policy practices and rationalities are needed. This paper focuses on the treatment of climate change in Australia’s Murray–Darling Basin (MDB) reforms over the past decade. While the MDB faces potentially significant drying trends due to climate change no reductions in future water availability due to climate change were formalized in the 2012 Basin Plan — a regulatory instrument agreed to by Australia’s National Parliament. The background, key dimensions and possible reasons for this decision are examined. Possible reasons for not formally reducing water deemed available in the future include the complexity and uncertainty of climate science, the cultural construction of “climate normal” based on long-term averages, and institutional settings that reinforce dominant “hydro-logical” approaches and rationalities. Minimizing the political, legal and financial consequences of attributing reductions in water allocations to climate change are also potential reasons. The case of the MDB, as outlined in this paper, demonstrates some of the ways climate change is causing systemic challenges for adaptive water governance, and that innovative approaches need to be embraced, including better processes for institutionalizing science/policy integration.

Subsidiarity Principle

A reform process is underway in the Murray–Darling Basin (Australia) to reallocate water from irrigated agriculture to the environment. The scale, complexity and politics of the recovery process have prompted interest in the role of local environmental water managers within state and federal governance arrangements. This paper examines prospects for a local role in environmental water management through the lens of the subsidiarity principle: the notion that effective governance devolves tasks to the lowest level with the political authority and capacity to perform them. The article defines and applies the subsidiarity principle to assess evolving federal–state–local interactions in environmental water policy, planning and practice in Australia's Murray–Darling River. In this context, subsidiarity is useful to clarify institutional roles and their coordination at a whole-of-river level. This analysis demonstrates opportunities for a local role in information gathering, innovation and operational flexibility to respond to opportunities in real time. It identifies significant limits to local action in upstream–downstream tradeoffs, economies of scale, capacity building and cost sharing for basin-wide or national interests, and accountability mechanisms to balance local, state and national rights and responsibilities. Lessons are relevant internationally for regions confronting complex allocation tradeoffs between human and environmental needs within multi-jurisdictional federal systems.

Australian Freshwater

Approximately 40% of Australian freshwater fish species are of conservation concern, largely because of the impacts of river regulation, habitat fragmentation and alien fishes. Murray hardyhead is a threatened fish endemic to the southern Murray–Darling Basin in Australia, which has declined significantly in range and abundance since European settlement. Conservation of the species has relied largely on environmental watering of off-channel wetlands where isolated populations persist. This became problematic during recent drought (1997–2010) because of competing demands for limited water, and resentment towards environmental watering programs from communities that themselves were subject to reduced water entitlements. In response, emergency conservation measures prioritised the delivery of environmental water to minimise applied volumes. Captive maintenance programs were established for fish rescued from four genetically distinct conservation units, with varying levels of breeding success. Several translocations of wild and captive-bred fish to surrogate refuge sites were also conducted. Future recovery of the species should secure existing natural and stocked populations and translocate fish to additional appropriate sites to spread risk and reinstate natural pathways for dispersal. The approach to the conservation of Murray hardyhead during extreme environmental conditions provides insights to inform the management of fishes in other drought-prone regions of the world.
