The Huanghe River basin's irrigation districts are divided into five regions based on factors like climate and water resources. Each region has unique water-saving needs. For example, regions with little rainfall need efficient irrigation techniques, while areas with high silt content require soil conservation. The study suggests using different strategies for each region, such as improving irrigation systems and reducing silt to save water. By tailoring water-saving measures to the specific characteristics of each region, the Huanghe River basin's irrigation districts can use water more efficiently and sustainably.
