Abstract:
Groundwater within the Indo‐Gangetic Basin (IGB) alluvial aquifer system forms one of the
world’s most important and heavily exploited reservoirs of freshwater. In this study we
have examined the groundwater system through the lens of its resilience to change – both
from the impact of climate change and increases in abstraction. This has led to the
development of a series of new maps for the IGB aquifer, building on existing datasets held
in Pakistan, India, Nepal and Bangladesh, a review of approximately 500 reports and papers,
and three targeted field studies on under‐researched topics within the region. The major
findings of the study are described below.
