Australia’s wheat yields more than trebled during the first
90 years of the 20th century but have stalled since 1990. In research published
today in Global Change Biology, we show that rising temperatures and reduced
rainfall, in line with global climate change, are responsible for the
shortfall.
This is a major concern for wheat farmers, the Australian
economy and global food security as the climate continues to change. The wheat
industry is typically worth more than A$5 billion per year – Australia’s most
valuable crop. Globally, food production needs to increase by at least 60% by
2050, and Australia is one of the world’s biggest wheat exporters.T
here is some good news, though. So far, despite poorer
conditions for growing wheat, farmers have managed to improve farming practices
and at least stabilise yields. The question is how long they can continue to do
so.
