Global threat to food supply as water wells dry up, warns top environment expert

Lester Brown says grain harvests are already shrinking as US, India and China come close to 'peak water'

Wells are drying up and underwater tables falling so fast in the Middle East and parts of India, China and the US that food supplies are seriously threatened, one of the world's leading resource analysts has warned.
In a major new essay Lester Brown, head of the Earth Policy Institute in Washington, claims that 18 countries, together containing half the world's people, are now overpumping their underground water tables to the point – known as "peak water" – where they are not replenishing and where harvests are getting smaller each year.
The situation is most serious in the Middle East. According to Brown: "Among the countries whose water supply has peaked and begun to decline are Saudi Arabia, Syria, Iraq and Yemen.

It is the first country to publicly project how aquifer depletion will shrink its grain harvest.
