New Delhi, July 28 - Agriculture Minister Sharad Pawar Tuesday said global warming would have an adverse impact on India's wheat bowl in four northern states and that the Prime Minister's Office was overseeing attempts to counter it.

'Punjab, Haryana, western Uttar Pradesh and parts of Bihar, which are our wheat bowls, will be adversely affected by global warming,' Pawar said in the Lok Sabha during his reply to a special discussion on the drought situation and floods in several states.

The agriculture minister said the government was serious about countering the phenomenon and a special section had been created for the purpose while a group of experts in the Prime Minister's Office were directly overseeing this work.

He said scientists at the Indian Council of Agricultural Research had changed their approach to developing new better 'weather resistant' varieties of wheat, to be able to reduce the impact of global warming.
