In early 2008, Saudi Arabia announced that, after being self-sufficient in wheat for over 20 years, the non-replenishable aquifer it had been pumping for irrigation was largely depleted.

In response, officials said they would reduce their wheat harvest by one eighth each year until production would cease entirely in 2016. The Saudis then plan to use their oil wealth to import virtually all the grain consumed by their Canada-sized population of nearly 30 million people.

The Saudis are unique in being so wholly dependent on irrigation. But other, far larger, grain producers such as India and China are facing irrigation water losses and could face grain production declines……

India’s water balance notes that 15 percent of its grain harvest is produced by overpumping. In human terms, 175 million Indians are being fed with grain produced from wells that will be going dry.

The comparable number for China is 130 million. Among the many other countries facing harvest reductions from groundwater depletion are Pakistan, Iran, and Yemen.

Australia’s Murray Darling river system is – for all intents and purposes – dead and what was once the fruit and vegetable basket of Australia is now a net importer of foods including fruit and vegggies.
