'''Drought in India''' has resulted in tens of millions of deaths over the 18th, 19th, and 20th centuries. [[India]]n [[agriculture in India|agriculture]] is heavily dependent on the [[climate of India|country's climate]]: a favorable southwest summer [[monsoon]] is critical to securing water for irrigating India's crops. In parts of India, failure of the monsoons causes water shortages, resulting in below-average crop yields.<ref name="IGARSS2017">{{cite journal |last1=Swain|display-authors=etal|first1=S |title=Application of SPI, EDI and PNPI using MSWEP precipitation data over Marathwada, India |journal=IEEE International Geoscience and Remote Sensing Symposium (IGARSS) |volume=2017 |pages=5505–5507 |doi=10.1109/IGARSS.2017.8128250 |year=2017|isbn=978-1-5090-4951-6}}</ref> This is particularly true of major drought-prone regions such as southern and eastern [[Maharashtra]], northern [[Karnataka]], [[Andhra Pradesh]], [[Odisha]], [[Gujarat]], [[Telangana]], and [[Rajasthan]].

== History ==
{{expand section|date=November 2015}}
In the past, droughts have periodically led to [[famine in India|major Indian famine]]s, including the [[Bengal famine of 1770]], in which up to one third of the population in affected areas died; the 1876–1877 famine, in which over five million people died; and the 1899 famine, in which over 4.5 million died.<ref name="Nash_2002_22-23">{{harvnb|Nash|2002|pp=22–23}}.</ref><ref name="Collier_2002_67">{{harvnb|Collier|Webb|2002|p=67}}.</ref> 1972 Maharashtra drought affected 2.5 crore people. In simple words, drought has destroyed India on a large scale.18 meteorological and 16 hydrological droughts occurred in India in the time span of 1870 to 2018. The most severe meteorological droughts were in the years 1876, 1899, 1918, 1965, and 2000, while the five worst hydrological droughts occurred in the years 1876, 1899, 1918, 1965, and 2000. The drought of 1899 can be classified as meteorological as well as hydrological and was the most severe documented drought India has ever experienced to date.

== Impact of El Niño ==

All such episodes of severe drought correlate with [[El Niño-Southern Oscillation]] (ENSO) events.<ref name="Kumar_2006">{{Citation |author1=Kumar KK |author2=Rajagopalan B |author3=Hoerling M |author4=Bates G |author5=Cane M |title=Unraveling the Mystery of Indian Monsoon Failure During El Niño |journal=Science |volume=314 |issue=5796 |pages=115–119 |year=2006 |doi=10.1126/science.1131152 |pmid=16959975 |postscript=.|bibcode = 2006Sci...314..115K }}</ref><ref name="Caviedes_2001_121">{{harvnb|Caviedes|2001|p=121}}</ref> El Niño-related droughts have also been implicated in periodic declines in Indian agricultural output.<ref name="Caviedes_2001_259">{{harvnb|Caviedes|2001|p=259}}.</ref> Nevertheless, ENSO events that have coincided with abnormally high sea surfaces temperatures in the Indian Ocean—in one instance during 1997 and 1998 by up to 3 °C (5 °F)—have resulted in increased oceanic evaporation, resulting in unusually wet weather across India. Such anomalies have occurred during a sustained warm spell that began in the 1990s.<ref name="Nash_2002_258-259">{{harvnb|Nash|2002|pp=258–259}}.</ref> A contrasting phenomenon is that, instead of the usual high pressure air mass over the southern Indian Ocean, an ENSO-related oceanic low pressure convergence center forms; it then continually pulls dry air from Central Asia, desiccating India during what should have been the humid summer monsoon season. This reversed air flow causes India's droughts.<ref name="Caviedes_2001_117">{{harvnb|Caviedes|2001|p=117}}.</ref> The extent that an ENSO event raises [[sea surface temperature]]s in the central [[Pacific Ocean]] influences the degree of drought.<ref name="Kumar_2006"/> Around 43 per cent of El Niño events are followed by drought in India.<ref>{{cite web | url=http://www.thehindu.com/opinion/editorial/preparing-for-a-poor-monsoon/article5948470.ece | title=Preparing for a poor monsoon | publisher=[[The Hindu]] | date=26 April 2014 | accessdate=27 April 2014}}</ref>
