Hi, I'm Sangita Vyas.

The Indian Government created the National Clean Air Programme (NCAP) with an ambitious aim to reduce air pollution in 131 cities by 40% by 2026. If successful, NCAP would be one of the most important environmental policies in history. We evaluate the effect of NCAP, and find a precisely estimated zero effect.

This paper studies the consequences of policy change for social desirability bias in survey responses in the context of a large-scale and highly-salient sanitation program in India.

This paper studies the extent to which the dramatic reduction in open defecation exposure in India between 2015 and 2019 can statistically account for the increase in child height over this period of time.

A smaller human population would produce less carbon emissions, other things equal. This fact has led to the view that an important benefit of the ongoing, global decline in fertility will be reductions in long-run temperatures. Here we assess the magnitude and economic significance of this relationship.

Why do so many rural north Indians defecate in the open?

Using cleaner fuels such as LPG is essential to reduce rural air pollution and improve health. What can policymakers do to achieve exclusive use of clean fuels in rural India?

The Swachh Bharat Mission has turned out to be a top-down programme in which villagers are often coerced into building latrines, with relatively little focus on latrine use.

Coercive and threatening tactics were used in all of the states to compel people to build and use latrines.
