Human activities can affect how much water the soil can hold, which impacts how rivers flow. Researchers studied the upper Yangtze River Basin in China to see how human actions change soil water storage. They used a model to show that soil water storage increased from 1976 to 2000. Factors like farming, population, and building reservoirs had a big influence on this. The number of people working in agriculture had the most significant impact on soil water storage. By understanding these changes, we can plan better for managing water resources in the future.
