The question asks about the initiative that was started to increase agricultural production and achieve self-sufficiency in food grains. Let's analyze the options given:
- Water Revolution: This is not a recognized revolution associated with agriculture or food grain production. It may relate to irrigation projects, but it is not a specific movement aimed at becoming self-sufficient in food grains.
- Green Revolution: The Green Revolution was a series of research, development, and technology transfer initiatives, occurring between the 1940s and the late 1960s, that increased agricultural production worldwide. In India, it began in the 1960s and involved the use of high-yield variety seeds, increased use of fertilizers, and improved irrigation practices. This led to a significant increase in food grain production, making India self-sufficient in this area. Therefore, this is the correct answer.
- Industrial Revolution: The Industrial Revolution was a period of major industrialization that took place during the late 1700s and early 1800s. It was not related to agriculture but rather to manufacturing processes.
- White Revolution: Also known as Operation Flood, this was a movement to increase milk production in India and is not related to the production of food grains.
Based on the explanation of each option, the Green Revolution is the initiative that was specifically aimed at increasing agricultural production and achieving self-sufficiency in food grains.
Therefore, the correct answer is Green Revolution.
