Since the year 2000, thousands of dams have been constructed worldwide, with estimates suggesting that over 3,700 large dams have been built by 2020. The exact number varies by region and type of dam, as many smaller and medium-sized dams are also being constructed. The trend reflects ongoing efforts to meet water supply, irrigation, and hydropower demands in various countries. However, the environmental and social impacts of these projects have sparked significant debate.
