英文摘要 | The alarming decline in groundwater (GW) storage threatens the sustainable development of the water‐energy‐food linkages of a country. India has experienced severe dry spells during the years 2002, 2004, 2009, and 2012. However, the relative contribution of factors affecting GW depletion (such as variability in precipitation rate, and groundwater extraction) still remains unknown. Here, we first evaluate the current GW condition by implementing Reliability, Resilience, and Vulnerability (RRV) analysis on the 5988 monitoring well observations spanning over a period of two decades. Our study further improves the existing studies by isolating the quantity of GW depletion due to precipitation and non‐precipitation (GW extraction) factors using a multivariate regression model. Our study indicates that the non‐precipitation factor is most responsible for GW depletion in North‐India at a rate of 3.5 cm per year This article is protected by copyright. All rights reserved. |
