  abstract = {{I}n the {M}editerranean region, considered as the prominent hotspot in future climate change projections, water scarcity becomes the main challenge for the agricultural sector. {T}his is mainly the case of the {T}unisian agriculture that is substantially based on rainfed crops to ensure food security. {T}hus, monitoring and assessing the vegetation conditions may provide accurate information, which allows improving water productivity and helps decision-making including water management. {C}urrently, satellite-derived vegetation data has been widely used to assess the crop production and the effect of water shortage and extreme climatic events. {I}n this context, the {FAO} portal to monitor water productivity through open-access of remotely sensed derived data ({W}a{POR}) {WAPOR} database was developed to monitor the water productivity through remotely sensed derived data. {T}he aim of this work is to evaluate {WAPOR} ability to estimate the biomass of rainfed annual crops in the {C}ap {B}on region in the {N}orth-{E}ast of {T}unisia. {T}he {WAPOR} products covering the study area are available at the national level ({L}evel 2) with a spatial resolution of 100 m. {M}easured aboveground of local cereals varieties of wheat, barley and oat and mixed fodder crops (faba-bean, triticale and vetch) was compared to the estimated actual evapotranspiration and interception ({ET}a_{WAPOR}), during four years with different climatic conditions. {T}he area of the considered agricultural fields varies from less than one hectare to around 10 ha. {T}he estimated cumulative actual evapotranspiration ({ET}a_{WAPOR}) calculated from the predicted decadal {ET}a shows an acceptable correlation with the monitored dry biomass ({R}-2 = 0.78) but with high {RMSE} value of around 2.7 ton/ha. {T}he performance of {WAPOR} estimation doesn't seem to vary with seasonal climatic conditions.},
