  2. Improving efficiency Off-farm

  3. Threats to water security

  4. Current Integrated Water Supply Scheme

  5. Early application of our water systems economics Cost-benefit of options commissioned on behalf of the Kimberley Expert Panel: Establishing the baseline price of water under future supply and demand scenarios

  6. Evaluating progress toward the Goal TERM Water in the Australian Economy By 2032: 5 Million more people 34% increase in irrigation efficiency 22% increase in household efficiency 15% decrease in rainfall ± water recycling ± seawater desalination ± rural water trading Perth $10.50 $5.80 Shadow price $kL $4.20 $3.80 2032 2001

  7. Impacts valued to date • Some of the research impacts that the Flagship has valued: • Identified an additional 20 Gigalitres per annum of recoverable water from Perth primary groundwater supply (saving about $200m in capital works); • Climate analyses underpinning accelerated investments in new water infrastructure in WA and Vic of $500M and $50M. • Identified irrigation water savings of about 295 GL in the Murrumbidgee catchment (worth about $200m on the permanent trade market).

  8. What we will look like in 2007-2008 • $80M annual R$D budget ($30M external) • Four Themes • Water Resource Observation Network • Better Basin Futures • Urban Water • Healthy Water Ecosystems • Regional portfolios: • SEQ • WA • MDB • Northern Australia • Research and adoption - in excess of 50 partners across Australia.
