Lucknow, India — I’m on my annual win-a-trip journey, in which I take a university student with me on a reporting trip. I’m traipsing through Indian villages with the winner, Austin Meyer of Stanford University, to tackle one of the world’s great whodunits: Why are hundreds of millions of children here stunted physically and mentally?

India is a vigorous democracy that has sent an orbiter to Mars. Yet its children are more likely to starve than children in far poorer nations in Africa.

In a remarkable failure of democracy, India is the epicenter of global malnutrition: 39 percent of Indian children are stunted from poor nutrition, according to government figures (other estimates are higher). Stunting is worse in India than in Burkina Faso or Haiti, worse than in Bangladesh or North Korea.

Here in Uttar Pradesh, a vast state of 200 million people in India’s north, the malnutrition is even more horrifying. By the government’s own reckoning, a slight majority of children under age 5 in this state are stunted — worse than in any country in Africa save Burundi, according to figures in the 2015 Global Nutrition Report.
