London: A group of researchers led by UK's University of Exeter concluded during their study that India is one of the countries facing the greatest risk of food insecurity due to climate change.
Published in the journal Philosophical Transactions of the Royal Society A, the global study was conducted taking into account 122 developing and least-developed countries. The purpose of the study was to ascertain the dangers posed by climate change to food insecurity.
Oman, Bangladesh, Saudi Arabia and India have been identified as the countries which are most vulnerable to food insecurity while moving from contemporary climate conditions to 2 degree Celsius global warming.
In broader terms, food insecurity can be described as a condition when people in the country lack access to a sufficient quality of affordable and nutritious food.
Richard Betts, a professor at the University of Exeter shed light on the change in global climate and its impacts. Climate change is expected to lead to more extremes of both heavy rainfall and drought, with different effects in different parts of the world, he said, adding that such extreme weather conditions can heighten vulnerability to food insecurity.
The larger problem at hand is food production which will be at risk of floods as a result of wetter weather conditions expected to come out of global warming. However, floods are not the only problem since the study concluded that frequent droughts can result in equal harm for agriculture.
"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 2 degrees Celsius global warming,” the report said.
Professor Richard Betts also issued a word of caution when he said, “Some change is already unavoidable, but if global warming is limited to 1.5 degrees Celsius, this vulnerability is projected to remain smaller than at 2 degrees Celsius in approximately 76% of developing countries.”
