Climate change may lead to extremes of heavy rainfall, drought.
Warming is expected to lead to wetter conditions on average — with floods putting food production at risk — but agriculture could also be harmed by more frequent and prolonged droughts in some areas, researchers said.

London: India is among the countries which are at the greatest risk of food insecurity due to weather extremes caused by climate change, a global study suggests.

Researchers led by the University of Exeter in the UK examined how climate change could affect the vulnerability of different countries to food insecurity — when people lack access to a sufficient quantity of affordable, nutritious food.

 

The study, published in the journal Philosophical Transactions of the Royal Society A, looked at 122 developing and least-developed countries, mostly in Asia, Africa and South America.

The countries at the greatest vulnerability to food insecurity when moving from the present-day climate to 20C global warming are Oman, India, Bangladesh, Saudi Arabia and Brazil, researchers said.

“Climate change is expected to lead to more extremes of both heavy rainfall and drought, with different effects in different parts of the world,” said Richard Betts, a professor at the University of Exeter. “Such weather extremes can increase vulnerability to food insecurity,” said Betts.

 

“Some change is already unavoidable, but if global warming is limited to 1.50C, this vulnerability is projected to remain smaller than at 20C in approximately 76 per cent of developing countries,” he said.

Warming is expected to lead to wetter conditions on average — with floods putting food production at risk — but agriculture could also be harmed by more frequent and prolonged droughts in some areas, researchers said.

Wetter conditions are expected to have the biggest impact in South and East Asia, with the most extreme projections suggesting the flow of the River Ganges could more than double at 20C global warming, they said.

 

The areas worst affected by droughts are expected to be southern Africa and South America — where flows in the Amazon are projected to decline by up to 25 per cent.
