The countries lacking
water (politically
weak and lacking in

Asia, the Middle East
and Northern Africa.
The daily water
consumption in these
countries is only 20
liters a day for one

165 liters a day for an
European family.

In Italy water isn't lacking but because of:
-the increase of 1.5 degrees in temperature;
-the decrease of the annual precipitation
by 20%;
- the stratum pollution;
-the dispersion of 40% of water along the
water pipes;
15% of the population for 4 months a year
are under the threshold of the 50 liters
of day need
