Drought in India

Drought has resulted in millions of deaths in India over the years. Indian agriculture is heavily dependent on the country's climate: a favorable monsoon is critical to securing water for irrigating India's crops. In parts of India, failure of the monsoons causes water shortages, resulting in poor yields. This is particularly true of major drought-prone regions southeastern Maharashtra, northern Karnataka, Andhra Pradesh, Odisha, Gujarat, Telangana, and Rajasthan.

History

Only about 35% of total agricultural land in India is irrigated and two-thirds of cultivated land is entirely dependent on rainfall. As such, the agricultural production system in the country is more vulnerable to damage from extreme climatic events, which causes increased water stress leading to inadequate water supplies for irrigation. Already, rises in average temperatures, changes in rainfall patterns, increasing frequency of extreme weather events, such as severe droughts and floods, and the shifting of agricultural seasons have been observed in different agro-ecological zones of India. Long drought spells during Kharif and increased temperatures and unseasonal heavy rains during the rabi season have caused serious distress to the farming communities in different states in recent years. Four major farming systems are prevailing in India: the irrigated system, rainfed system, silvo-pastoral system, and desert farming.

In the past, droughts have periodically led to major Indian famines, 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.
