Historic Mexico drought causing food crisis

Crops are wilting in the countryside, and the capital’s water shortage has turned dire as Mexico grapples with its worst drought in more than half a century.

By Ken Ellingwood, Reporting from Mexico City – In the parched Mexican countryside, the corn is wilting, the wheat stunted. And here in this vast and thirsty capital, officials are rationing water and threatening worse cuts as Mexico endures one of the driest spells in more than half a century. A months-long drought has affected broad swaths of the country, from the U.S. border to the Yucatan Peninsula, leaving crop fields parched and many reservoirs low. The need for rain is so dire that water officials have been rooting openly for a hurricane or two to provide a good drenching. “We really are in a difficult situation,” said Felipe Arreguin Cortes, deputy technical director for Mexico’s National Water Commission. This is supposed to be Mexico’s wet season, when daily rains bathe farmland and top off rivers and reservoirs. But rainfall has been sporadic and unusually light — the result, officials say, of an El Niño effect this summer that has warmed Pacific Ocean waters and influenced distant weather patterns. Mexico’s hurricane season has been mild, with no major hits so far this summer, though a weak Hurricane Jimena dropped plenty of rain on parts of Baja California and the northwestern state of Sonora last week. The sparse rainfall nationwide has made 2009 the driest in 69 years of government record-keeping, Arreguin said. … “Although no one wants to recognize it, there is a food crisis,” said Cruz Lopez Aguilar, president of a national federation representing rural dwellers. He and others say increasing imports to make up for lost crops could raise food costs. … Even before the drought, managing water was one of the most vexing issues for Mexico City, which 500 years ago was a big lake. Now paved in asphalt and concrete, the city pipes in much of its water (then, through separate plumbing, expels wastewater to prevent flooding during rainy times). Since most rainwater pours down storm drains into the sewer network, it is not absorbed into the underground aquifers that are the city’s main source of water. Decades of over-pumping is emptying those deposits and causing Mexico City to sink, in some places by more than a foot a year.
