Core Viewpoint - The National Bureau of Statistics reported that the total summer grain production in China is expected to reach 299.48 billion jin in 2025, indicating stable production and harvest [1] Irrigation and Water Management - Water is crucial for agriculture, and irrigation support is essential for achieving high yields. In response to drought conditions in regions like Shaanxi and Henan, water departments have implemented measures, providing a total of 57 billion cubic meters of irrigation water across 43 million acres [1] - The Jiaokou Abstract Wei Irrigation District has undergone modernization, featuring 30 pumping stations and 344 kilometers of irrigation channels, significantly improving irrigation efficiency and drought resilience [2] - The average yield in large and medium-sized irrigation districts is 1.5 to 2 times the national average, highlighting their importance in ensuring food security [3] Technological Advancements in Irrigation - The introduction of digital tools in irrigation management, such as real-time monitoring of water conditions, has improved the efficiency of water resource allocation. For instance, the Anhui Province has developed a digital twin irrigation system to optimize water usage across 10.6 million acres [4] - The use of advanced irrigation techniques, such as drip and spray irrigation, has led to significant water savings, with one acre requiring only 90 cubic meters of water compared to 120 cubic meters in traditional methods [6] Water Resource Allocation - In the Huai River Basin, 16 large reservoirs have provided 1.2 billion cubic meters of water for irrigation, while in the Yellow River Basin, key reservoirs have entered drought management modes to ensure water supply during critical periods [5] - The Ministry of Water Resources is focusing on precise irrigation strategies to meet the water needs of crops, ensuring the safety of urban and rural water supply in drought-prone areas [5] Water Conservation Efforts - By the end of 2024, the area of water-saving irrigation projects in China is expected to reach 63.8 million acres, with over 40 million acres utilizing high-efficiency irrigation methods. The effective utilization coefficient of irrigation water has improved from 0.530 in 2014 to 0.580 [7] - The Ministry of Water Resources plans to establish a comprehensive water-saving policy framework to enhance agricultural water efficiency and ensure water security [7]
