Blistering crop-withering temperatures that also risk the health of agricultural workers could threaten swathes of global food production by 2045 as the world warms, an industry analysis has warned.
The latest assessment by risk company Verisk Maplecroft released on Thursday calculates that heat stress already poses an “extreme risk” to agriculture in 20 countries, including agricultural giant India.
The climate crisis is already stoking heatwaves and other extreme weather events across the world, with hot spells from India to Europe this year expected to hit crop yields.
Temperature spikes are causing mounting concern for health, particularly for those working outside in sweltering conditions, which is especially dangerous when humidity levels are high.
But the coming decades are expected to expand the threat to 64 nations by 2045 – representing 71 percent of current global food production – including major economies China, India, Brazil and the United States.
