Operation Flood, launched in 1970, was India's major dairy development program that made the country the largest milk producer in the world. It was spearheaded by Verghese Kurien and the National Dairy Development Board (NDDB), establishing the Anand pattern of dairy cooperatives. This program transformed India's dairy industry through cooperative milk production, processing, and marketing - it has nothing to do with seafood, oil exploration, or processed food.
