Notas:
1) Hasta el año 2005 inclusive: 
  
 - En cada Comunidad Autónoma el consumo de agua por hectárea estimado  en la muestra, se elevaba a la superficie total de regadío de la  Encuesta sobre Superficies y Rendimientos de Cultivo en España  (ESYRCE). En años sucesivos, se han utilizado como variables  auxiliares de la elevación, las superficies de regadío por las tres  técnicas de riego. 
   
 - En el proceso de estimación de volumen de agua según su origen  (superficial/subterránea) se ha introducido una modificación con  objeto de tener en cuenta el agua que las explotaciones agrarias  adscritas a comunidades de regantes captan con sus propios medios  (auto-abastecimiento) para complementar el agua suministrada por  dichas comunidades. Este hecho debe ser tenido en cuenta en el  cálculo de las variaciones entre los años 2004 y 2005.
