A one degree celsius rise in temperature associated with increase in carbondioxide in atmosphere could hit wheat production in India unless “adaptation” strategies are adopted, according to a government report on climate change.
In the absence of adaptation and CO2 fertilisation benefits, a one degree Celsius rise in temperature alone could lead to a decrease of six million tonnes of wheat production, the report submitted to the UN said. India had a record wheat production at 85.93 million tonnes in 2010-11 crop year.
“Magnitude of the impact of climate change on wheat production in India assessed through simulation studies indicated that an increase in 1 degree Celsius mean temperature, associated with CO2 increase, would not cause any significant loss to wheat production in India, if simple adaptation strategies such as change in planting date and varieties are used,” said India’s second National Communication to the United Nations Framework Convention on Climate Change, released by environment minister Jayanthi Natarajan today.
Such strategies can reduce the extent of loss caused by high temperature, it said.
