Most of the world’s 58,700 biggest dams have reached end of their life posing a major threat to the whole world !

Dams would not exist in the Hindu nation, lakes and reservoirs would be created instead!

New York (North America) – Most of the 58,700 large dams worldwide were constructed between 1930 and 1970 with a design life of 50 to 100 years, and at 50 years a large concrete dam “would most probably begin to express signs of aging.” Ageing signs include increasing cases of dam failures, progressively increasing costs of dam repair and maintenance, increasing reservoir sedimentation, and loss of a dam’s functionality and effectiveness. As per the report published by the United Nations, by the year 2050 majority of the world’s population will be living in the area of influence of such old dams. This report surveyed dams in the United States, France, Canada, India, Japan, Zambia and Zimbabwe.

The UNU Institute for Water, Environment and Health has published a report titled ‘Ageing Water Infrastructure: An Emerging Global Risk’. As per this report, the lifespan of many dams has already ended or will end soon.

This report further mentions

1. In India, around 1,115 large dams are set to reach the 50 years mark by 2025. These and many such old dams across the world pose a huge threat.

2. Worldwide, the huge volume of water stored behind large dams is estimated at 7,000 to 8,300 cubic kilometres enough to cover about 80% of Canada’s landmass under a meter of water. 93% of all the world’s large dams are located in just 25 nations.

3. 32,716 large dams (55% of the world’s total) are found in just four Asian countries: China, India, Japan, and the Republic of Korea.
