TS4.6 - Water Productivity Improvement in Practice from remote sensing data at multiple geographical scales (FAO ,HE Delft, IWMI, eLeaf, Metameta, Wageningen University & Research)
Convener (s): FAO
Co-convener (s): IHE Delft, IWMI, eLeaf, Metameta, Wageningen University & Research
The session will explore a range of water productivity indicators based on remote sensing data for possible improvement at various geographical scales. At country level, gross biomass water productivity indicators were compared to actual and reference evapotranspiration, sourced from remote sensing water data for a 10 years period (2009-2019) for 20 countries of the League of Arab States from the FAO WaPOR portal. This analysis highlights that half of the countries have increased their water productivity and biomass production in particular in irrigated areas, although this is mostly done at the expense of an increase in water use. At irrigation scheme level, water productivity monitoring through the real time water data (temporal resolution of 10 days) enables a practical increase in agricultural production and reduced water consumption. Specific smartphone applications can be built to propose advice directly to farmers, not only for irrigated agriculture, but a wider range of farming systems. Priorities of the phase 2 of the WaPOR project, started in January 2021, will report the identified applicable solutions, which have been prioritized for Egypt, one of the 10 countries of the project.
