The most straightforward — and likely the least controversial — method for improving water productivity that Grant and his co-authors suggest is expanding efforts at reducing freshwater consumption, such as replacing single - flush toilets with dual - flush toilets or installing high - efficiency shower heads and washing machines.
Eliminating water shortages depends on a global attempt to raise water productivity similar to the effort launched a half - century ago to raise land productivity, an initiative that has nearly tripled the world grain yield per hectare.
Shifting to more water - efficient crops and switching from flood irrigation to drip irrigation are two ways farmers can boost water productivity.
