White Revolution or Operation Flood, launched on 13 January 1970, was the world's largest dairy development program and a landmark project of India's National Dairy Development Board (NDDB). It transformed India from a milk-deficient nation into the world's largest milk producer, surpassing the United States in 1998 with about 22.29 percent of global output in 2018. Within 30 years, it doubled the milk available per person in India and made dairy farming India's largest self-sustainable rural employment generator. The program was launched to help farmers direct their own development, and to give them control of the resources they create.

The National Dairy Development Board (NDDB) is a statutory body set up by an Act of the Parliament of India and an Institution of National Importance. It is under the ownership of the Ministry of Fisheries, Animal Husbandry and Dairying of the Government of India. The main office is in Anand, Gujarat with regional offices throughout the country. NDDB's subsidiaries include Indian Dairy Machinery Company Ltd (IDMC), Mother Dairy and Indian Immunologicals Limited, Hyderabad, NDDB Dairy Services, NDDB Mrida Ltd., NDDB CALF Ltd. The Board was created to finance and support producer-owned and controlled organisations. Its programmes and activities seek to strengthen farmer cooperatives and support national policies that are favourable to the growth of such institutions. Cooperative principles and cooperative strategies are fundamental to the board's efforts.
