Is warming behind India's depleting groundwater?


Changing rainfall patterns may be depleting India’s groundwater storage more than withdrawals for agricultural irrigation, says a new study published in January by Nature Geoscience.  While India’s diminishing groundwater is widely attributed to over extraction, especially in the northern agricultural belts of Punjab and Haryana, the study holds decline in rainfall caused by the rise in the temperatures in the Indian Ocean — a major factor in monsoonal rainfall patterns over the Indo-Gangetic Plain —  to be a more important cause.
