Irrigation farming:
Securing food production

T
he global population is expected to
grow from 7.4 billion to 9.1 billion by
2050 (See Figure 1) and as population
increases, the demand for water for
non-agricultural purposes will also grow.
World water demand is projected to increase
by 55% between 2000 and 2050, and most of
this increase will come from manufacturing,
electricity production, and urban and domestic
use. So, in a drier world, getting the amount
of water used by irrigation under control is a
necessity. New technologies might go a long
way toward helping us reach that goal.
