    The evolution and performance of river basin management in the Murray-Darling Basin

    We explore bioregional management in the Murray-Darling Basin (MDB) in Australia through the institutional design characteristics of the MDB River Basin Organization (RBO), the actors and organizations who supported and resisted the establishment of the RBO, and the effectiveness of the RBO. During the last 25 years, there has been a major structural reform in the MDB RBO, which has changed from an interstate coordinating body to an Australian government agency. Responsibility for basin management has been centralized under the leadership of the Australian government, and a comprehensive integrated Basin plan has been adopted. The driving forces for this centralization include national policy to restore river basins to sustainable levels of extraction, state government difficulties in reversing overallocation of water entitlements, the millennium drought and its effects, political expediency on the part of the Australian government and state governments, and a major injection of Australian government funding. The increasing hierarchy and centralization of the MDB RBO does not follow a general trend toward multilevel participative governance of RBOs, but decentralization should not be overstated because of the special circumstances at the time of the centralization and the continuing existence of some decentralized elements, such as catchment water plans, land use planning, and water quality. Further swings in the centralization–decentralization pendulum could occur. The MDB reform has succeeded in rebalancing Basin water allocations, including an allocation for the environment and reduced diversion limits. There are some longer term risks to the implementation of reform, including lack of cooperation by state governments, vertical coordination difficulties, and perceived reductions in the accountability and legitimacy of reform at the local level. If implementation of the Basin plan is diverted or delayed, a new institution, the Commonwealth Environmental Water Holder, can play a major role in securing and coordinating environmental water supplies

    Effectiveness of Surface Treatment Techniques for Composite Bonding with Different Contamination Levels

    Get PDF
    Various surface treatment techniques have been developed to promote adhesive bond performance for composite structural components in aerospace applications. The condition of the pre-bond surface is critical to achieving desirable bond quality. Contamination on bonding surfaces is well recognized as a major threat to ultimate bond performance. Variation in contamination level has brought additional challenges into manufacturing process control. High fidelity surface treatment techniques are required for effective removal of contaminants over a wide range of contamination levels. In this study, a common contaminant, i.e. silicone mold release, was introduced to pre-bond composite surfaces with different concentrations. Plasma and laser surface treatment techniques were performed and their effectiveness in restoring and enhancing desirable bond quality was investigated. Surface characterization techniques, including water contact angle goniometry, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy, were conducted to assess the condition of contaminated surfaces and the improvement induced by plasma and laser surface treatments. Failure modes from a customized double cantilever beam test were investigated before and after surface treatments. Fundamental mechanisms of plasma and laser surface treatments on the composite bonding surfaces were also investigated

    This unique book brings together 27 chapters from some of the world’s leading practitioners and experts on environmental water, communities, law, economics and governance. Its goal is to understand the many dimensions of water in the Murray- Darling Basin and provide guidance about how to implement a water management plan that addresses the needs of communities, the economy and the environment. The comprehensiveness of topics covered, the expertise of its authors, and the absolute need to take a multidisciplinary approach to resolving the “wicked problem” of governing our scarce water resource makes this volume a must read for all who care about Australian communities and the environment

    Daniel Connell\u27s thesis analysed Martin Heidegger\u27s ontological and epistemological critique of Nietzsche in his later writings. It argued that Heidegger\u27s understanding of Nietzsche is flawed, and presented an alternative account of Nietzsche\u27s ontology and epistemology

    Large dams and the 'risk society'.

    No full text
    The ongoing controversy about the social, economic and environmental costs and benefits of building large dams is a sub-set of the even larger debate about how we should move to a sustainable world. A central part of this debate has been the discourse about the development of ‘the risk society’, one in which policy makers believe they can reliably predict future problems and manage them. The term ‘risk society’ was popularized by Ulrich Beck in the 1980s. He described the ethos of the state – thinking of governments in western Europe and North America – as animated with confidence that humans could conquer nature in all its manifestations and deal with future hazards by continually assessing potential risk and planning to deal with them. He did not suggest that they would be successful but diagnosed this as the underlying ideology of what is sometimes called the ‘modern’ state

    Resistance versus resilience

    No full text
    Since people first began attempting to manipulate rivers to increase the benefits they could gain there have been two distinct management approaches. They can be described broadly as resistance and resilience. One involves working to control rivers and the other as working with rivers. The benefits of the former are usually more immediate and larger than are those of the latter. In the second case benefits are not only longer in coming they are also more diffuse and harder to identify
