TAILIEUCHUNG - Managing diffuse water pollution in South East Queensland: An analysis of the role of the Healthy Waterways Partnership

Drought attributable in significant part to climate change is already causing acute water shortages in large parts of Australia, Asia, Africa, and the United States. Just last month, California water officials warned that the state – whose enormous agricultural and computer industries are heavily water-dependent – is facing “the worst drought in modern history.”1 Shrinking snowcaps are reducing river flows and water supplies across China, India and Pakistan – countries where more than one billion people already lack access to safe drinking water and adequate sanitation. The impact of water scarcity and declining water quality on business will be far-reaching.

The increasing demand for water has lead to pressure on supply sources impacting both the availability of water and water quality across the region. This has had significant environmental consequences including the decline of several threatened native species and the degradation of natural bushland. This report presents a situational analysis of the region drawing out the key water management issues it faces and the contextual factors that have come together to cause them. Initially the report set out to consider only catchments that directly drained into Moreton Bay. As the work progressed a problemshed approach that recognized the interrelated linkages between urbanised zones throughout the region revealed itself as a more appropriate way to tackle the issues that exist. The problemshed approach asks what are the issues and beyond watersheds what is the geographical scope of the factors contributing to or influencing these issues Mollinga et al 2007 . Throughout South East Queensland water flows where it is needed. It is imported from the Sunshine Coast to Brisbane urban area from North Stradbroke Island to Redlands and -as with other regions around the world with rapidly growing
