Aided by Harvard experts, officials are tackling housing, pollution, and traffic problems — and solving them. (Harvard University)

Problematic housing, snarled traffic, and stubborn air pollution are three of the most prominent challenges in greater Mexico City. They are the same problems that threaten to overwhelm megacities worldwide. And they are problems that Harvard has a hand in studying and mitigating in Mexico City.

In 1992, the United Nations called Mexico City’s air quality the planet’s worst, so bad that flying birds, overwhelmed, would fall dead from the sky. By 1998, the U.N. called Mexico City the world’s most dangerous city for children’s health.

Thanks to stringent regulatory reform in the last two decades, the situation has dramatically improved. Air quality in Mexico City now resembles that in Los Angeles: not wonderful, but not catastrophic. New laws have reduced the city’s once prodigiously dirty industrial footprint, which had included lead smelters.
