Notes:
1) Up 2005 (included): 
  
 - In each Autonomous Community, the water consumption per hectare estimated  in the sample was raised to the total irrigation area of the  Survey on Crop Areas and Yields in Spain  (ESYRCE).In successive years, irrigation areas by the three irrigation  techniques have been used as complementary  variables of the raise. 
   
 - In the proccess of estimation of water volume by origin  (surface water/groundwater) it has been introduced a modification in  order to take into account the water that agrarian operations   affiliated to irrigation communities capture by their own means  (self-supply) to complement the water supplied by  said communities. This fact must be taken into account in the  calculation of the variations between the years 2004 and 2005.
