Which is best for you?
Australia’s top freshwater resources are the best for drinking, irrigation and farming, says a study by the Australian Institute of Water and Atmospheric Science.
Key points:The findings show there is a link between water quality and irrigation, and farmingThe study shows farmers can have more water in the ground to irrigate crops, and more water for irrigationWater quality can be affected by the climate, pollution, and other factorsThe study looked at 14 water resources, including rivers, lakes, streams and groundwater.
It found that in terms of irrigation water quality, water quality was associated with temperature, precipitation, and precipitation-to-groundwater ratios.
It said, although water quality varies across the country, water quantity and availability was the main determinants of water quality.
The study found that a high rainfall was associated to a low water quality for irrigation, whereas water quality had no association with rainfall.
“The study demonstrates that water quality impacts on crop yield, irrigation, water management, and production are linked to climate, precipitation and pollution,” said study lead author Andrew White.
Water quality impacts agriculture in different waysThe study compared water quality across Australia’s 12 water resources.
Water Quality impacts cropsA major finding was that a low rainfall was more associated with a low quality of water for crops.
The study said the difference was significant in the agricultural sector.
“This was particularly the case for crops like rice, maize and wheat, which require very high water demands,” the study said.
“Higher water demands in the food sector and associated with increased water availability for irrigation are the drivers for water quality changes.”
These impacts can also be significant for water availability and production in the water-intensive farming sector.
“In terms of agriculture, water scarcity has also been shown to be a significant factor.”
Water scarcity has been shown in some places to be linked to crop yields and irrigation quality, with some research finding that irrigation yields in drought-prone areas were lower than those in other parts of the country,” the research said.
It also found that the amount of rainfall a water resource received varied significantly across the continent.
The researchers said that irrigation quality could have a significant impact on rainfall.
For example, a lower-quality irrigation could affect crop yields in the long term, but could also lead to increased pollution and lead to reduced production in crops.
The research showed that in some parts of Australia, water availability was also affected by rainfall.
There were some regions where water availability varied, but there were regions where it varied by just one tenth of a degree.
For irrigation, the researchers found that drought conditions were associated with lower water availability, but this was only for water resources that had experienced heavy rainfall.
This means water availability may also be influenced by climate and pollution.”
It may be that higher water availability in the short term is linked to a lower water quality in future,” the researchers said.
