How water scarcity will shape the new century.
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.
