Water scarcity started 15 years ago

28.08.2009
New analysis shows that the water scarcity being experienced in southeast Australia started up to 15 years ago.

While the results from the work by senior CSIRO researcher, Dr Albert van Dijk, may not surprise many people, it provides scientific evidence of the shift.

The finding follows the first ever national and comprehensive analysis of 30 years of on-ground and satellite observations of Australia’s water resources.

Dr Albert van Dijk told the the Sixth International Scientific Conference on the Global Energy and Water Cycle in Melbourne today that the analysis provides a valuable, new insight into the country’s water balance.

”The data shows the first signs of diminishing water availability in Australia appeared somewhere between 1993 and 1996 when the rate of water resource capture and use started to exceed the rate of streamflow supply,” Dr van Dijk said.

Dr van Dijk’s work is part of the water information research and development alliance between the CSIRO’s Water for a Healthy Country Flagship and Bureau of Meteorology in which scientists are building an observation and modelling system that will provide water balance estimates across Australia.

“If this technology had been available to us in the mid-1990s, the onset of dry conditions could have been detected earlier,”

says Dr van Dijk.Long-term on-ground records and 30 years of satellite observations are combined with models that integrate and analyse the data within a powerful computer system that provides comprehensive, detailed and reliable information about the nation’s water resources.

”If this technology had been available to us in the mid-1990s, the onset of dry conditions could have been detected earlier,” Dr van Dijk said.

“The results of the study underscore the importance of good water information for water resource planning.”

The data also reveals that the impact of the drought on Australia’s current water resources is broadly consistent with both the historical trend and climate change predictions.

“Parts of Australia have had record low rainfall the last several years, but our records aren’t very long and the drought may still be within natural limits.”

“What makes the situation appear so much worse is that the sixties and seventies were quite wet. That’s also when we started capturing river flows in large reservoirs for our growing cities and irrigated agriculture. In retrospect it appears we have become over-reliant on what is now looking like ‘bonus’ rainfall during that time.”

The observation system that is developed will assist the Bureau in conducting regular water resource assessments and produce national water accounts.

National Research Flagships

CSIRO initiated the National Research Flagships to provide science-based solutions in response to Australia’s major research challenges and opportunities. The 10 Flagships form multidisciplinary teams with industry and the research community to deliver impact and benefits for Australia.

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

Im Focus: Entangled atoms shine in unison

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
