In October, Wu was overjoyed to see fields of mature rice swaying in the breeze in his fields, which run along the local Hunsha irrigation canal. "I will have a bumper harvest this year, because of the canal that irrigates my farmland," he said.
Irrigated farmland has provided a solid foundation for China to boost its annual food supply from 320 billion kg in 1980 to 500billion kg in 2007, agricultural officials said.
China expanded irrigated farmland from 730 million mu in 1978 to 867 million mu in 2007, according to the Ministry of Agriculture (MOA). This farmland totals 46 percent of all arable land.
To date, China has created 434 large-scale irrigated areas, averaging more than 300,000 mu each. These irrigated areas account for one-eighth of the country's arable land but can produce one-quarter of its food.
But China has much to do when it comes to water conservation for farm irrigation, where the efficiency of water use is low. China produces less than 1 kg of grain with 1 cubic meter of water, less than half the level in developed countries.
