Recent rain is not enough to revive drought-hit cereal crops, landowners have warned.
The Country Land and Business Association said sustained rainfall was needed to ensure cereal crops survive.
It would take more than a few showers to ensure grain crops are brought to healthy levels, said CLA East Midlands director Andrew Shirley.
A drought could mean failed crops and higher food prices, he said.
“We have been experiencing the second driest spring since records began.
“A drought status will mean a crackdown on farmers taking water from rivers to irrigate fields, increasing the risk of failed crops and causing the cost of food to rocket.”
Mr Shirley voiced his fears to farm minister Jim Paice during talks at Cereals 2011 in Lincolnshire.
Reform of the water abstraction licensing system should not prevent land managers from receiving a fair allocation of water, said Mr Shirley.
“Taking water from rivers and reservoirs is vital to ensure good harvests so that we can meet the demands of a growing global population.”
The government is looking to find ways of encouraging and enabling farmers to develop more sophisticated ways uses of water.
Mr Paice said the government was looking at extending grant support to farmers who want to build reservoirs to store water.
It was also looking at making abstraction licences tradable so farmers could sell abstraction rights to other growers.
