20 April 2017, Rome--- Measuring how efficiently water is used in agriculture, particularly in water-scarce countries, is going high-tech with the help of a new tool developed by the UN’s Food and Agriculture Organization. The new WaPOR open-access database has gone live today during an event at the Organization’s headquarters in Rome. According to the food agency, worldwide water utilization – the majority of which is used by agriculture – has outpaced the rate of population growth for most of the last century and an increasing area of water supply is either at or beyond the limit of sustainable use.
