A new study states that the world’s supply of vegetables could plummet to more than a third by 2050 unless urgent action is taken to tackle the source of the problem: climate change.

The said study claims that global average yields of common crops such as soybeans and lentils are set to decrease by 35% and 9%, respectively, due to rising temperatures and water shortages.

Researchers from the London School of Hygiene and Tropical Medicine warn that the depletion of the world’s vegetable supplies could then affect public health as key ingredients of a healthy diet could become harder to come by.

They also estimated the future impact of key factors that influence crop production which include levels of greenhouse gases, reduced availability of water for irrigation, and rising temperatures.

The team writing in the journal called Proceedings of the National Academy of Sciences suggests that new crop varieties and developments in agriculture and mechanization are necessary steps to protect vegetable supplies.
