CAIRO: Global food shortages have placed the Middle East and North Africa in a quandary, as they are forced to choose between growing more crops to feed an expanding population or preserving their already scant supply of water.
For decades nations in this region have drained aquifers, sucked the salt from seawater and diverted the mighty Nile to make the deserts bloom. But those projects were so costly and used so much water that it remained far more practical to import food than to produce it. Today, some countries import 90 percent or more of their staples.
Now, the worldwide food crisis is making many countries in this politically volatile region rethink that math.
The population of the region has more than quadrupled since 1950, to 364 million, and is expected to reach nearly 600 million by 2050. By that time, the amount of fresh water available for each person, already scarce, will be cut in half, and declining resources could inflame political tensions further.
"The countries of the region are caught between the hammer of rising food prices and the anvil of steadily declining water availability per capita," Alan Richards, a professor of economics and environmental studies at the University of California, Santa Cruz, said via e-mail. "There is no simple solution."
