The economically backward states, the tribal and remote areas, and areas prone to natural disasters like droughts and floods have a higher percentage of people with food insecurity.
Hunger is both a cause and effect of poverty and indicates food insecurity. Hunger is of two types: Chronic hunger and seasonal hunger. Chronic hunger is a result of consistently low quantity and quality of diet.
Seasonal hunger is a result of low quantity and quality of diet for a short period of time. Both chronic and seasonal hunger has decreased in rural and urban India. Food security requires elimination of present and future hunger.
India has made rapid strides in attaining self-sufficiency in food, and to provide food security to its large population. The introduction of modern farming methods brought about the Green Revolution in India marked by a dramatic increase in the production of food grains.
The success of the Green Revolution was not uniform across India. In the states of Punjab and Haryana, wheat production increased by more than four times from 1965 to 1995. The states of Tamil Nadu and Andhra Pradesh saw a significant rise in rice production. The states of Maharashtra, Madhya Pradesh, Bihar and Orissa, and the north-eastern states did not show any significant rise in food grain production.
