While some of the water used by irrigated agriculture is reused by other downstream users or diverted to meet environmental needs, a large share is consumed in evapotranspiration (the share being close to the total with modern irrigation techniques). Losses also result in groundwater sources which are no longer economic to pump (OECD, 2010a). For the country as a whole, irrigation accounts for 58% of total water abstractions and for about 72% of water abstractions for consumptive water use in 2005 and 2006 (non-consumptive use includes water use for electricity generation or for cooling purposes) according to the most recent published data (see Figure 4.2). This is a bigger share than in most OECD countries behind only Greece, Turkey and Australia.
