Problem
Long-term shortage of wheat
Nature:
Because wheat is a basic food for many parts of the world, wheat shortages and the high prices resulting from a shortage, can seriously affect the economies of importing countries. In a developing country whose local crops have failed, such a shortage may lead to famine.
Incidence:
Australia’s wheat yields more than trebled during the first 90 years of the 20th century but have stalled since 1990. Research published in Global Change Biology in 2018 (https://theconversation.com/changing-climate-has-stalled-australian-wheat-yields-study-71411) shows that rising temperatures and reduced rainfall, in line with global climate change, are responsible for the shortfall.
