At the global level, agriculture is the main consumer of water with more than 70\% of the use, using it with an efficiency of around 40\%.

One way to increase this efficiency is to accurately quantify the water needs of crops for proper irrigation management. Water needs can be estimated from the reference crop evapotranspiration value (ETo).
