SUMMARY:Evaluating the application of FAO-WaPOR data to support Colombia
 ’s National Water Study on water consumption in the agricultural sector

DESCRIPTION:Colombia's official water accounting method (ENA) relies on in
 tensive field data and is only updated every four years\, making it diffic
 ult to capture seasonal variability driven by El Niño and La Niña. This 
 study explores whether freely available satellite data from FAO's WaPOR pl
 atform can support more timely and continuous agricultural water monitorin
 g. By combining WaPOR's evapotranspiration products with ENA's crop mask i
 n an open\, adapted\, and reproducible notebook-Python-based framework\, w
 e compare water consumption estimates at the sub-basin level across Colomb
 ia for 2020. Results show strong spatial agreement (R² = 0.83) between bo
 th methods\, with a systematic offset explained by the difference between 
 potential and actual evapotranspiration.
