CSIRO PROJECT TO ASSESS CLIMATE CHANGE IMPACT ON SOUTH-WEST WATER SUPPLY

Minister for Climate Change and Water, Senator Penny Wong, today launched the South West Sustainable Yields project - a comprehensive assessment of water yield out to 2030 in the south-west of Western Australia.

The Rudd Government committed $5.19 million in funding for the CSIRO-led project to assess the future impacts of climate change and other factors on water supply at the March 2008 Council of Australian Government’s meeting.

“Stream flow in the south-west has declined by over 50 per cent since 1976, so it is clear that we are already seeing changes in the climate in this part of Australia,” Senator Wong said.

“This project will provide crucial information on current and future water yield, taking into account climate change and other factors, such as changes in agricultural production.”

The study is one of three new sustainable yields projects being undertaken by CSIRO to build on the Murray-Darling Basin Sustainable Yields project, which is due for completion shortly.

The South West Sustainable Yields (SWSY) project will cover 39,043 square kilometres of surface water catchment and 37,186 square kilometres of groundwater management areas from Geraldton to Albany.

The study is set for completion in December 2009.

Earlier this year, the Rudd Government delivered $35 million for the Harvey Water Piping Project to deliver multiple benefits including more efficient irrigation, enhanced environmental benefits and improved water security for Perth.

“The Australian Government is working with the states and territories to prepare for the impacts of climate change, including reduced water availability,” Senator Wong said.

Along with the south-west study, work has commenced on the Tasmanian Sustainable Yields project and the Northern Australia Sustainable Yields project.

Once completed, these comprehensive scientific assessments of water yield in Australia’s major water systems will allow future decisions about water use, planning and management to be based on the best available scientific data.
