4 Posible evolución costes componentes Agriculture uses 75% of water

5 Posible evolución costes componentes Irrigation on vineyards was prohibited in Spain

6 Posible evolución costes componentes Vineyards are mainly irrigated using drip irrigation and it is a low consuming crop

7 Winegrapes are probably the single crop that maximum income it does not come from maximum yield A Grapes 1 Eur/kg B Grapes 0,5 eur/kg 20 Eur 9 Eur

8 Irrigation management makes the difference A Grapes: 1 Eur/kg D grapes: 0,2 Eur/kg

10 Irrigation Posible strategies: evolución IS costes componentes -Grapes for premium red wines -Grapes for young red wines -Grapes for white wines -Grapes for sparkling wines
