United Nations Report on Dams: In a report of the United Nations, thousands of dams around the world have been declared a major threat. Among them are those dams, which are five decades old or even older. The report states that in 2025, more than one thousand large dams in India will become almost 50 years old and such old structures all over the world can become a threat in future.

According to the report, by 2050, most of the world’s population will be settled under these thousands of dams built in the 20th century and due to this they will be under serious threat from old dams. The report titled ‘Aging Water Infrastructure: An Emerging Global Risk’ has been prepared by the United Nations University’s Canada-based Institute of Water, Environment and Health.

Thousands of dams in dangerous condition

The report said that most of the world’s total 58,700 large dams were constructed between the years 1930 to 1970. These are the dams which were built for 50 to 100 years. The report says that the dam made of concrete probably gets old after 50 years. That’s why thousands of dams of the world have reached a dangerous position at this time, there is a danger of their wall breaking. The report says that the maintenance cost of most old dams increases and their water storage capacity also decreases.

55 percent dam in four Asian countries

According to the analysis of the United Nations University, by 2050, most of the world’s population will be settled downstream of these thousands of dams. This has been said in the report after studying the dams built in India, America, France, Canada, Japan, Zambia and Zimbabwe. According to this, 55 percent of the total dams i.e. 32,716 big dams are in four Asian countries – China, India, Japan and South Korea. Most of them will soon be more than 50 years old.

3.5 million people in danger here

According to the report, in India alone, 1,115 big dams will become 50 years or more in 2025. More than 4,250 big dams in the country will become 50 years old in 2050 and 64 big dams will become more than 150 years old in 2050. The report said that if the Mullaperiyar Dam in Kerala was built 100 years ago in India, and if there is something wrong with it, then about 3.5 million people are in danger.
