Book excerpt: Decision-Making in Water Resource Policy and Management: An Australian Perspective presents the latest information in developing new decision-making processes. Topics covered include key aspects of water resources planning, recent water resource policy changes in irrigation, urban, and environmental considerations, the evolution of a water market, a number of case studies that provide real examples of improved decision-making, transfer of the Australian experience overseas, and challenges for the future. Many countries are experiencing major water scarcity problems which will likely intensify with the continued impacts of climate change. In response to this challenge, there is increased worldwide focus on the development of more sustainable and integrated water resource policies. The Australian experience over the past three decades has led to major improvements in the decision-making processes in water resources policy and management, particularly in response to drought and climate change, providing a great model on which other nations can use and adapt. This information is essential to early to mid-career practitioners engaged in policy, planning and operational roles in all fields of water resource policy and management, and catchment management. - Summarizes key results from three decades of changes in Australian water resource policy - Illustrates how Australian knowledge is being used in other countries and how this might be expanded - Provides international practitioners with real examples of where and how the Australian knowledge is assisting in other situations
