"Drought in India has resulted in tens of millions of deaths over the course of the 18th, 19th, and 20th centuries.
All such episodes of severe drought correlate with El Niņo-Southern Oscillation (ENSO) events. El Niņo-related droughts have also been implicated in periodic declines in Indian agricultural output."
