The researchers studied ways to save water in the irrigation district of Shandong Province. They found that most water from the Yellow River in Shandong is used for farming but not very efficiently. There is a big potential to save water by using better irrigation methods. To save water, they suggest measures like lining canals to prevent water loss, managing water use more accurately, adjusting crop types, and improving irrigation techniques on farms. The next steps include projects to improve water management, creating ways to compensate for using less water on farms, and spreading awareness about water-saving methods in the area.
