Here's how Hridayesh Gupta's incentive scheme works:
Women between the ages of 18 and 28 are eligible.
For every three months that they do not get pregnant, they receive Rs 250 per month.
If they don't get pregnant for over a year, it gets them an increment. If they do, the payment is scrapped.
Traditional midwives, or dais, establish whether the women are pregnant or not at camps held in the project zone.
In the next phase of his project, Gupta wants to cover five areas and about 40,000 women in all. This works out to an outlay of Rs 12 crore, or $2.6 million, a year.
He has so far spent $25,000 (Rs 11.47 lakh) of his own money, and hopes to keep the project going till the youngest woman in his group turns 33, which is another 15 years.
