Global Warming Impacts Wheat Production

A recent study published in Nature Food has shown that global warming in the Indian Ocean has given rise to a drier climate in Australia. A dry climate is not suitable for wheat production. As a result, wheat production has fallen in Australia. If global warming continues to take place at a similar rate, wheat producers are likely to experience more challenges in wheat cultivation.

The study has found that the change in the climatic pattern due to global warming is known as the Indian Ocean Dipole (IOD). If IOD is in a positive phase, there won’t be enough rainfall to produce wheat. A normal weather condition suitable for wheat cultivation can produce up to 2.5 tonnes of wheat per hectare in a year. However, a dry climate driven by positive IOD events could bring down wheat cultivation to 1.5 tonnes per hectare.
