Bihar drought of 1966–1967 was a minor drought with relatively very few deaths from starvation as compared to earlier famines. The drought demonstrated the ability of the Indian government to deal with the worst of drought-related circumstances. The official death toll from starvation in the Bihar drought was 2353, roughly half of which occurred in the state of Bihar. No significant increase in the number of infant deaths from famine was found in the Bihar drought. The annual production of food grains had dropped in Bihar from 7.5 million tonnes in 1965–1966 to 7.2 million tonnes in 1966–1967 during the Bihar drought. There was an even sharper drop in 1966–67 to 4.3 million tonnes. The national grain production dropped from 89.4 million tonnes in 1964–1965 to 72.3 in 1965–1966 — a 19% drop. The rise in prices of food grains caused migration and starvation, but the public distribution system, relief measures by the government, and voluntary organizations limited the impact. On a number of occasions, the Indian-government sought food and grain from the United States to provide replacement for damaged crops, however US food aid was limited by Lyndon B. Johnson in retaliation for Indian criticism on the US's role in the Vietnam War. The government set up more than 20,000 fair-price stores to provide food at regulated prices for the poor or those with limited incomes. A large-scale drought in Bihar was adverted due to this import, although livestock and crops were destroyed. Other reasons for successfully averting a large-scale drought were employing various drought prevention measures such as improving communication abilities, issuing drought bulletins over the radio, and offering employment to those affected by drought in government public works projects. The Bihar drought of 1966–1967 gave impetus to further changes in agricultural policy and this resulted in the Green Revolution. 1972 Maharashtra drought After several years of good monsoons and a good crop in the early 1970s, India considered exporting food and being self-sufficient. Earlier in 1963, the government of the state of Maharashtra asserted that the agricultural situation in the state was constantly being watched and relief measures were taken as soon as any scarcity was detected. On the basis of this, and asserting that the word famine had now become obsolete in this context, the government passed "The Maharashtra Deletion of the Term 'Famine' Act, 1963". They were unable to foresee the drought in 1972 when
