Although treating wastewater generally ranks alongside police and fire safety, schools, and transit as the top priorities of any sensible city hall, new ideas about cleaning up sewage almost never attract headlines or TV airtime. In its 90-year history, for instance, The New Yorker, the most urbane and expansive magazine in the country, has never published a feature article on sewage treatment.

In March 1999, not long after he was sworn in as the 47^th mayor of Oakland, Jerry Brown called Lesley Estes, the supervisor of the city’s watershed protection program. Brown, who is now California’s governor, wanted the city staffer he called “Creek Lady” to describe the most formidable ideas she had to conserve natural areas, make parks more beautiful, and clean up the city’s waters.

Karachi, the world’s second largest city by population, is emerging from the grips of a deadly heatwave. A persistent low pressure system camped over the Arabian Sea stifled ocean breezes and brought temperatures in excess of 113°F (45°C) to the city of 23 million people in June. The searing heat disrupted electricity and water service, making life nearly unbearable. All told, officials estimate the heatwave killed at least 1,200 Pakistanis, more than twice as many as have died in terrorist attacks this year.

As the U.S. has undergone a rapid and massive shift to natural gas from coal, one benefit has gone almost entirely overlooked: the amount of water needed to cool the nation’s power plants has dropped substantially.

Before world oil prices collapsed late last year, shop owners closest to the banks of the Rio Grande River in Piedras Negras joked that they could hear the groans of Texas drilling rigs advancing toward their fast-growing northern Mexico city.

“Tackling climate change could be the greatest global health opportunity of the 21^st century,” asserts the newest report by the Lancet Commission on Health and Climate Change.

The landscape of the northeastern Indian state of Meghalaya is rapidly changing. What was once a predominately agricultural economy has shifted to coal mining with significant consequences for people and the environment. “Once you extract coal from the land, it’s really hard to go back to an agricultural economy,” says ECSP’s Sean Peoples in an interview with Wilson Center NOW, about the Global Choke Point film, Broken Landscape.

Researchers have been warning about future water scarcity for decades, but new data reveals a majority of the world’s largest aquifers are already running out of water.
