The Ministry of Agriculture has warned a lingering drought will damage the year's summer crop output, but analysts say the country's grain crop prices won't be much affected.

Nearly 15 million hectares of arable land have been affected by the drought triggered by high temperatures and strong winds, latest figures from the State Flood Control and Drought Relief Headquarters revealed.

Drought has affected some part of China every day since the beginning of the year. Under the impact of global warming, the situation is likely to further deteriorate in the foreseeable future.

Currently, 25 percent more Chinese land is affected by drought than the average in previous years.

"Summer crops are in a crunch situation. If the drought continues in wheat producing areas, China will be unable to reach its summer crop targets," said a ministry statement.

A preliminary survey by the Wheat Chapter of the China National Association of Grain Crops in worst-stricken Hebei Province projects lower wheat output, the staple of summer crops.

"The decline will not seriously affect the year's grain reserve and supply. But the official forecast has not yet been released," an agency spokeswoman said, adding that similar surveys are under way in other drought-hit regions.

The drought started in northern China in late April and spread to Shanxi, Inner Mongolia, Ningxia, Xinjiang, Gansu, Hubei, Henan, Liaoning, Chongqing, Sichuan and Yunnan.

China's wheat output is expected to go down by 2.53 percent year-on-year to 101.8 million tons even if the weather turns favorable, said the China National Grain and Oils Information Center this month.

There will be no rainfall in the next three days in northern China and the Huanghe and Huaihe River Valleys where drought has wrought havoc, according to a Friday forecast by weathermen.
