الملخص
With the increasing pressure of agriculture on water and land, achieving high waterproductivity is essential. Models such as FAO’s Water Productivity Portal (WaPOR)aim to estimate water productivity by providing yield and evapotranspiration. In thisstudy, the aim was to validate the yield product of WaPOR in the Beqaa Valley,Lebanon. The study was focused in two main fields. Yield of Potato and wheat, plantedduring 2017-2018, was validated in one field. In addition, the yields of barley, vetch,barley/vetch mixed fields and vetch/oat mixed fields, planted during 2012-2019,werevalidated in the other field by comparison against farmer reported yields. StatisticalIndicators such as percentage relative error (RE), Root Mean Square Error (RMSE),R2,correlation (r), and bias were used for this validation.Wheat yield showed better results at a resolution of 30 m than that at a 100 m whererecorded RE% of 1.14% 20% for all crops at both levels 2 and 3. Thisinaccuracy in crop yield estimations was attributed to inaccuracy in farmer reportedyields which was detected in both fields, the standardized LUE max, harvest Index andmoisture content.
