Department of Primary Industries, Parks, Water and Environment, June 2010 3 Strategic Water Information and Monitoring Plan, Tasmania Foreword The issue In recent years water has become a pressing public policy issue for Australian society. As water demand increases and supply dwindles, the strain on existing water supplies has reached new heights. Protracted drought and mounting evidence of climate change have added momentum behind a growing community and political will to see improvements in both our understanding of water resources and the way we manage them. The challenge Better management of water poses a national challenge, requiring a coordinated response. Our ability as a community to reach agreement on the tough issues relies on access to accurate, reliable water information that is freely available and of the highest standards. Key to making these decisions and arriving at sound policy is a definitive water data source that stands above reproach. Australian Aligned with this need, the Australian Government assigned the Bureau of Government Meteorology (the Bureau) responsibilities under the Water Act 2007 to response compile and deliver comprehensive water information for the country. As part of the Australian Government’s long term framework for water security, Water for the Future, $450 million was allocated to the Bureau over 10 years to deliver the Improving Water Information Program. This program includes development and maintenance of an integrated, national water information system which will be freely accessible to the public. Details of the full suite of Bureau objectives and deliverables can be found at www.bom.gov.au/water . A partnership Vital to the success of the Bureau’s mission is the partnership and model… cooperation of all State and Territory Governments and all water data collecting organisations in each jurisdiction. One of the vehicles for effective collaboration is the Jurisdictional Reference Group for Water Information (JRGWI), established to provide regular input to the Bureau’s activities, and bringing to the table the experience and wisdom of respected senior officials from across the water sector. …and putting The Modernisation and Extension of Hydrologic Monitoring Systems it into practice Program (the M&E Program) is an $80 million fund administered by the Bureau and available to organisations named under the Water Regulations 2008. The M&E Program is aimed at improving technologies employed by those who collect water information, and enabling better approaches to data transfer and standardisation. Coordination activities are also supported through the M&E Program via funding for Strategic Water Information Coordinators (SWICs) in each State and Territory. SWICs have been tasked with bringing together key stakeholders in their jurisdiction to distil State/Territory priorities in water data collection, and to set these out in a series of Strategic Water Information and Monitoring Plans (SWIMPs). Strategic The SWIMPs provide a framework for describing where we are going and plans… how we will get there. Each SWIMP has been produced with a whole of jurisdiction focus to encapsulate the current state of play in water information and monitoring, describe the gaps, issues and opportunities that exist, and articulate a series of priorities, strategies and actions that will bring us closer to the end vision of better water information for all. Department of Primary Industries, Parks, Water and Environment, June 2010 4 Strategic Water Information and Monitoring Plan, Tasmania …and how Through the M&E Program the Bureau is able to assist the States and they contribute Territories to get closer to our agreed view of what constitutes a fit-for- to the solution purpose hydrologic observing system in each jurisdiction. The Bureau looks to the SWIMPs to provide guidance on how best to invest M&E Program funds to achieve this goal. In this regard, the SWIMPs are a vital product. The future In closing, the Bureau appreciates the energy and expertise that has been applied in the preparation of this SWIMP, and thanks all of the officers that have participated in its development and review. Our special thanks go to the lead author of the SWIMP, Department of Primary Industries, Parks, Water & Environment.
