India's mass sterilisation drive
India is expected to overtake China to become the most populous country in the world in the next five years.
Even with a fast growing economy, the challenge of providing education and employment to a growing population of more than one billion remains steep.
For decades, one solution has been a massive sterilisation programme run from makeshift medical camps across the country.
Operating conditions are often very poor but demand is rising, driven by cash incentives from the state.
