And this is a familiar story in the south of Jiangsu province, a manfucaturing hub along the Yangtze River that produces just about everything, from textiles to electric vehicles.

When the government constructed the world's biggest dam in the 90s - the Three Gorges on the Yangtze River - it saw protests and criticism over its handling of relocation and compensation for thousands of villagers.

The campaigns led to the discovery, for example, of uranium reserves in the lower Yangtze River Basin and a major molybdenum-tungsten deposit in the Nanling Mountains in southern China.

A further 9,000 people were evacuated from the Chongming District, an island at the mouth of the Yangtze River, city authorities said.

For instance, the construction of large dams, such as the Three Gorges Dam on the Yangtze River, has significantly reduced the sediment supply downstream.
