1 Practical application: Guadiana river basin water footprint (Spain) M. Ramón Llamas Complutense University of Madrid Water Footprint and Virtual Water Trade Side event Water Observatory - M. Botin Foundation 5th World Water Forum, Istanbul, 18 March 2009 Side publication of the WWDR-3 Joint venture of M. Botin Foundation and NeWater Maite M. Aldaya University of Twente

2 Water footprint with distinction of green and blue water (surface and groundwater) and related economic analysis for the Guadiana basin Guadiana WF Source: CHG (2008) First time applied in a river basin in this way A recent Spanish regulation requires the WF analysis for the preparation of the EU river basin management plans that MS have to send to the EU in 2009, and then every 6 years.

7 Guadiana WF: Conclusions CONCLUSIONS Agriculture main water consuming sector (95%), low €/m 3 Most of the water is used for low economic value crops. This is typical for continental agriculture in Spain. Economic water productivity (€/m 3 ): vegetables vineyards olive trees cereals Surface and groundwater distinction. Outcomes not very different due to several factors: legal restrictions in GW use, one of the most regulated river basins in Spain. From “more crops and jobs per drop” towards “more cash and nature per drop”
