One of the most signicant challenges in the global arena is to lower
the pressure on natural water resources, among other resources, due
to the rapid growth of population. It is clear today that technologies
can serve as a key to a much more ecient exploitation of natural
resources (Water, Soil, Energy & Materials). New technologies and
smart solutions are estimated to contribute almost two-thirds of the
additional quantities of water needed in the next 30 years.
