A for Athirapally, B for Bodhghat, C for Cauvery, D for Dibang, E for Etalin, seems to be the new growth alphabets from the Prime Minister’s Office. With the economic growth in negative territory, depression in the corner, the old and trusted Big Dams as major infrastructure to push up expenditure and hope for the growth was a formula used even in 1930s by US president Franklin D Roosevelt to bring the US economy out of the Great depression of 1929. It started with the Tennessee Valley Authority Act of May 1933, which then was pushed as growth model to other countries. In India it came in the form of Damodar Valley Corporation (DVC) Act of 1948.
However that 20th century model was a failure even then, as the first CEO of the DVC, Sudhir Sen wrote. That model is no longer relevant in 21st century except possibly as an easy route to corruption and kickbacks. These dams and hydropower projects are no longer even economically viable and better options are now available for irrigation and power. In the changing climate scene they are even less relevant places of worship (temples). Dams and hydropower projects are seeing slow down across the globe, not just in India.
