Global Food Insecurity Can Be Fueled
According to research published in the journal Nature Human Behaviour, an additional eight million people in India, for instance, will probably experience severe food insecurity during a week of extreme heat.

France’s Paris A study released on Monday shows that a few days of intense heat can be enough to prevent billions of people who are already struggling to put food on the table from being able to do so, even in the midst of record-high temperatures throughout the world.
According to research published in the journal Nature Human Behaviour, an additional eight million people in India, for instance, will probably experience severe food insecurity during a week of extreme heat.
They discovered that even if total food precarity increases by less than one percent, the same heatwave results in millions of men, women, and children at danger of starvation throughout the 150 countries they studied, especially in tropical and subtropical zones.
According to World Bank predictions, in 2022, moderate to severe food insecurity would affect up to 30% of the world’s population.
The analysis of how heat affects food availability is typically restricted to crop output declines, with effects noticed across months or years.
However, the latest study shows that when it is linked to income, the impact can be felt right away.
According to lead author Carolin Kroeger of Oxford University, “if it gets hot today, there might be food insecurity within just a few days because people can’t work, which means they can’t earn income and afford to buy food.”
In jobs where remuneration is directly correlated with productivity, whether in agricultural harvests or piece-rate labour, such effects are often greatest.
In West Bengal, for instance, women who carry bricks are paid according to how many bricks they move each day. They suffer income losses of up to 50% when the hot weather makes carrying fewer bricks necessary.
The conclusions presented here are highlighted by recent reporting from AFP.
To avoid the sweltering heat, Syrian blacksmith Murad Haddad gets up early and works at the anvil with his five brothers in shifts.
“We are dying in this heat. I barely have time to care for my six children, he remarked. But if I don’t work, I won’t be able to support myself.
Records were broken.
“You see stronger effects in countries with lower incomes, more agricultural employment, and more vulnerable employment,” Kroeger added.
According to Kroeger, those who had just gone through a particularly hot week were more likely to develop health issues and “difficulties living on their present income,” which would result in a much reduced income.
These impacts built up over time; the greater the number of hot days in a week, the greater the effect.
In 2021, excessive heat prevented people from working 470 billion hours, or approximately 1.5 weeks of work per person worldwide.
The findings come at a time when food prices are still high due to ongoing inflation and a month after India, the world’s largest exporter of rice, limited exports because of harmed harvests.
But there are other issues than supply and price.
Researchers have discovered that many of the staple crops and legumes that are consumed throughout much of the world experience a considerable loss in vital nutrients as a result of rising temperatures.
“A lot of heat records were broken in the last year or two, so I definitely think some of the things we saw might get worse,” Kroeger said.
The balance could still tip, she continued, “but there are also a few things that could help, like microinsurances and reforms to labor laws.
Even if the world achieves the Paris Climate Agreement objective of limiting warming well below two likely experience at least 30 so-called “deadly heat days” annually by 2080, predicts the UN’s IPCC climate scientific advisory group.
