How can we assess water use for crops' development?

It takes water to grow crops and produce energy and it takes a lot of energy to treat and move water.

Food and energy are equally dependent upon each other.

The connection between the systems is known as the Water-Energy-Food Nexus.

Biodiversity is a Solution, with many Neglected and Underutilized Species or NUS, that can better use water for food production whith less energy.
