Operation Flood
Operation Flood in India, a project of the National Dairy Development Board (NDDB) was the world's biggest dairy development programme which made India, a milk-deficient nation, the largest milk producer in the world, surpassing the USA in 1998, with about 17 percent of global output in 2010–11, which in 30 years doubled the milk available per person, and which made dairy farming India’s largest self-sustainable rural employment generator. All this was achieved not merely by mass production, but by production by the masses.
