Murray-Darling Authority Hosts Regional Planning Forum

Poh-Ling Tan and John Mackenzie from the Water Planning Tools project gave a presentation to the planning staff of the Murray Darling Basin Authority on 27th November, 2008. The presentation was the keynote address as part of a forum on regional planning hosted by the Authority to gather insights and learnings for the development of the Basin Plan.

The requirement of the Murray-Darling Basin Authority to orchestrate the development of a basin-wide water resource plan has instigated what can only be described as the most contentious and ambitious planning exercise ever undertaken in Australia. Under the Australian Commonwealth’s Water Act 2007, the Authority is to prepare a strategic plan – to be known as the Basin Plan – for the integrated and sustainable management of water resources in the Murray-Darling Basin. Although the complexity of this exercise will require an unprecedented level of co-ordination and collaboration in resource planning, the ten years of accumulated experience in water planning across the country promise a wealth of learnings that may contribute to its overall success.

The presentation focused on the key lessons for regional planning as revealed from the project’s research into large-scale water planning. These lessons included:

  1. Community expectations will be for an inclusive, transparent and equitable engagement processes, in exchange for their investment of time, energy and expense
  2. Clarity around the process, role and rationale of  community participation and involvement in the development of the Basin Plan will be necessary for effective collaboration.
  3. The scope of community involvement should distinguish between collaboration and seeking feedback on pre-determined outcomes in the preparation phase of the Basin Plan.
  4. Participant commitment to the process and the opportunities for social learning in the basin will depend on the extent of meaningful input into the decision-making process.
  5. There is an identified need for improved methods for making trade-offs in water allocation decisions in a collaborative way.
  6. The absence of adequate Indigenous participation and representation remains a key issue and impediment to effective planning.
  7. Integrating the diverse forms of knowledge required of the planning process, particularly the scientific, local and cultural knowledges, will be a complex and challenging aspect of reaching transparent allocation decisions.
  8. Water planning agencies in general are not convinced of the benefits of a properly conducted collaborative process – but for reasons of fairness, equity and pragmatism, the Basin Plan will require the insights into complex issues brought about through the integration of multiple stakeholders’ perspectives.

Murray-Darling Basin Sustainable Yields Project

The final report from the CSIRO Murray-Darling Basin Sustainable Yields Project has now been released by the Australian Government. The project is the most detailed study of water availability in the Murray Darling Basin, and was the biggest research contract at $11 million ever undertaken by the CSIRO.

The key findings from the report are:

  • Total flow at the Murray mouth has been reduced by 61 per cent and the river now ceases to flow through the mouth 40 per cent of the time, compared with one per cent in the absence of water resource development;
  • The median decline for the entire Basin is projected to be 11 per cent by 2030 – nine per cent in the north and 13 per cent in the south;
  • Under the median 2030 climate, diversions in driest years would fall by more than 10 per cent in most New South Wales regions, 20 per cent in the Murrumbidgee and Murray regions, and from around 35 per cent to 50 per cent in the Victorian regions;
  • Under the dry extreme 2030 climate, diversions in driest years would fall by around 40-50 per cent in New South Wales regions, over 70 per cent in the Murray, and 80-90 per cent in major Victorian regions;
  • By 2070 the median climate under high global warming is expected to be broadly similar to the dry extreme 2030 climate; and
  • Current groundwater use is unsustainable in seven of the 20 high-use groundwater areas in the Basin and will lead to major drawdowns in groundwater levels in the absence of management intervention.

Future Proofing the Murray-Darling Basin

Professor Mike Young, Research Chair Water Economics and Management, School of Earth and Environmental Sciences University of Adelaide, presented a seminar for the Collaborative Water Planning Project entitled Future Proofing the Murray-Darling Basin. The seminar was hosted by the Griffith University Socio-Legal Research Centre, as part of their Lighthouse Series on the 2nd June, 2008.

Prof. Young is a member of the Wentworth Group of Concerned Scientists which has been contributing thought-provoking and innovative ideas and comments on water policy since 2002.

The presentation expanded on the ideas in Prof. Young and Jim McColl’s discussion paper (available for download here).
