According to the latest reports, China’s irrigation and drainage engineering system has been continuously improved during the “14th Five-Year Plan” period. As of now, the national irrigated farmland area has exceeded 1.09 billion mu (approximately 72.7 million hectares), an increase of over 53 million mu compared to the end of 2020. The grain output from this irrigated area accounts for more than 80% of the nation’s total grain production in 2025.
Agricultural water use efficiency and benefits have continued to rise. The national effective utilization coefficient of irrigation water for farmland has increased to 0.583, up by 3.2% from the end of the “13th Five-Year Plan” period. The area covered by water-saving irrigation projects has reached 638 million mu, while the average water consumption per mu of irrigated farmland has decreased to 342 cubic meters. This has enabled a steady increase in both irrigated area and grain output while maintaining stable agricultural water use.
Simultaneously, significant efforts have been made to promote integrated management of rivers, lakes, ditches, and farmland. Support has been provided for the implementation of 70 key regional waterlogging drainage capacity construction projects, which have substantially enhanced agricultural disaster prevention and mitigation capabilities.
