Climate change could shift rainfall line

Scientists say Goyder's Line in South Australia could be shifted south on maps because of climate change.

The line was originally drawn on maps after the 1860s drought as a boundary to indicate where graziers to the north required government help.

It is now thought of as a rainfall line indicating the areas suitable for cropping.

Research by the South Australian Research and Development Institute (SARDI) and the CSIRO suggests higher temperatures and less rain will change the agricultural landscape, moving the line further south.
