The goal of the study is to figure out how to divide up the water in the Yangtze River Basin over the next 20 years. The researchers looked at the current water situation in the area and studied how water is used in different places. They found that there are problems with how water is shared and that the demand for water will increase as the economy grows. The researchers came up with a plan to divide the water in the basin in the future. They looked at things like sharing water between different areas, balancing economic needs with environmental concerns, and making sure there's enough water for cities and farms.
