What's the big deal? Basically, there are three sectors of people in India: the farmers, who are largely self-sufficient in food; the urban people, who don't cultivate, but can buy food; and the poor—rural and urban. According to Shariff, while almost 40 per cent of India sleeps hungry, there has been no attempt by the government to even define the poor. Says he: "They don't even know how to identify. They don't know how to think." In a recent paper, he has shown that 80 per cent of Indians do not use 2,400 kilocalories of food—the internationally accepted norm for survival. That they are alive is a miracle. In fact, the lowest 5 per cent of the economic strata, who eke out a life on less than Rs 4 a day, get a little more than half their true energy requirements. The next 5 per cent, spending between Rs 4 and Rs 4.66 daily, are undernourished by 33 per cent. Those who spend between Rs 4.66 and Rs 5.50 a day, manage to eat only three-fourths of their requirements.
