New and unique data on how much water crops use

Dec 12 2021

ICARDA and the United Nations Food and Agriculture Organization (FAO) recently organized a two-day workshop to document and share the outcomes of a project that uniquely establishes the amount of water used by key crops in regional settings, providing vital data for farming approaches and government policies.

Evapotranspiration (ET) is how soil and plant surfaces lose water to the atmosphere (evaporation) combined with how water leaves small openings of the plants’ leaves (transpiration). The process of evapotranspiration means the water is no longer stored in the soil or the plant. To manage water resources effectively and determine water requirements for fundamental crops, scientists and farmers seek to measure ET accurately.

Currently, many remote sensing (RS) evapotranspiration estimates are available for use in regional planning and policy development. Still, they suffer from uncertainties as they are not rigorously validated, especially in the Near East and North Africa (NENA) Region.
