Overpumping agriculture will lead to a food collapse

Lester R. Brown : Author
A potential food collapse may result from aquifer overpumping. Water tables are now falling in countries that together contain half the world’s people. An estimated 400 million people (including 175 million in India and 130 million in China) are currently being fed by farms and processes that rely on overpumping. Saudi Arabia has announced that, because its major aquifer is largely depleted, it will be phasing out wheat production entirely by 2016.
