title: How water scarcity will shape the new century.
abstract: Water resources are increasingly being overexploited, such that current food production, which relies heavily on irrigation schemes, is unsustainable. Many steps, including improved irrigation techniques, more water-efficient crops and animal protein production, etc., will be needed to raise water productivity across the board. Water must in future be recognised as a scarce resource and not taken for granted.
