The correct answer is (b) M. S. Swaminathan.
The term “Evergreen Revolution” was coined by M. S. Swaminathan in 1987 to describe a new approach to agricultural development that would focus on sustainable and environmentally friendly methods. Swaminathan argued that the Green Revolution, which had focused on increasing crop yields through the use of high-yield varieties of crops and chemical fertilizers, had not been sustainable in the long run. He called for a new approach that would focus on increasing productivity while also conserving natural resources and protecting the environment.
The Evergreen Revolution has been implemented in a number of countries, including India, China, and Brazil. It has been successful in increasing crop yields and reducing poverty in some areas. However, it has also faced challenges, such as the need to develop new technologies that are both productive and sustainable.
Norman Borlaug, Raj Krishna, and R. K. V. Rao are all well-known agricultural scientists who have made significant contributions to the field. However, none of them coined the term “Evergreen Revolution.”
