Historical and projected
groundwater withdrawals
in cubic miles per year*

Changing zones
Tropical zones are expanding
20 miles a decade, pushing
other climates poleward; the
populous Mediterranean region
could get much drier.

Both drier and wetter
For every 1°C rise in tempera-
ture, the air holds 7 percent
more water. This dries Earth’s
surface and makes rainfall,
including storms and cyclones,
less frequent but more intense,
escalating the risk of flooding.

These seven countries
account for 74% of global
groundwater withdrawals. *Projections using RCP 6.0

Food shortages
In India the aquifers feeding
the Ganges River are being
depleted faster than anywhere
else in the world. Farmers
depend on this water source.

BUT LESS WATER
Agriculture accounts for more
than two-thirds of ground water
extraction worldwide. Entire
ecosystems become jeopardized
as water is increasingly pumped
from aquifers that can’t be
recharged fast enough.
