Operation Flood was launched on 13 January 1970 and it was the world's largest dairy development program.
It was a project of India's National Dairy Development Board (NDDB).
India was transformed from being a milk-deficient nation to one of the largest milk producing nation in the world.
Within 30 years, it was able to double the milk available per person in India and made dairy farming India's largest self-sustainable rural employment generator.
It was launched to help farmers direct their own development and giving them control of the resources they create.
The process has been called white revolution as it was achieved by production by masses not just by mass production.
