The Genil-Cabra Irrigation Project (PIGC), Coletividade Santaella, is located in Andalusia, southern Spain. It was evaluated the irrigation in 2004/2005 and 2005/2006 seasons. After collecting all data it was made a study to determine indicators to irrigation efficiency for methodology used by Mateos (2007) complemented with the Digital Terrain Model - DEM, Geographic Information System - SIG and farmer interviews. After the farmer interviews and compared the information with the orthophotos obtained from the web's records it was possible determine the water productivity (WP). It was observed that the biggest values were detected by "recinto" analyze, both in 2005 and 2006 season, due to low water volume demanded, observed in the sensors. In the parcel WP calculation, it was used the crop evapotranspiration as denominator; however in the "recinto" WP calculation it was used the applied water. Since the irrigation was deficiency, then likely will have a bigger WP in the "recinto" level. The values obtained were 4.06;0.37(€ m-3) to "recintos" and parcels (2005) and 6.60;0.27(€ m-3) to "recintos" and parcels (2006). These results are similar to encountered by Garcia-Vila et al. (2008) and Lorite et al. (2004b).
