India has a large and growing population, increasing the demand for food. To improve food production and quality, the government implemented several initiatives in the 1960s and 1970s, including using fertilizers, better irrigation, and high-yielding seed varieties. This led to the "Green Revolution" which substantially increased cereal crop yields. In the 1970s, Operation Flood was launched to increase milk production through the National Dairy Development Board, making India the largest milk producer - the "White Revolution". These efforts helped India improve its food security through higher-yielding hybrid crops and seeds.
